Robert Proctor: Nazi Science and Ideology | Lex Fridman Podcast #268

What is the heroic action for scientists in Nazi Germany?

Science in many respects actually is a full collaborator in the most horrific forms of Nazi genocide, Nazi exclusion.

What goes to the mind of a big tobacco executive?

Cigarettes have killed more than any other object than all the world of iron, all the world of gunpowder. Nuclear bombs have only killed a few hundred thousand people. Cigarettes have killed hundreds of millions. There's no contest. Cigarettes have killed far more and are far more preventable.

What is the nature of human ignorance? The following is a conversation with Robert Proctor, historian at Stanford University, specializing in 20th century science, technology and medicine, especially the history of the most controversial aspects of those fields. Please allow me to say a few words about science and the nature of truth. The word science is often used as an ideal for a methodology that can help us escape the limitation of any one human mind in the pursuit of truth. The underlying idea here is that individual humans are too easily corrupted by bias, emotion, personal experience and the usual human craving for meaning, money, power and fame. And the hope is that the tools of science can help us overcome these limitations in striving for deeper and deeper understanding of objective reality. From physics to chemistry, biology, genetics and even psychology, cognitive science and neuroscience. But history shows that these tools of science are not devoid of human flaws, of influence from human institutions, of manipulation from people in power. As we talk about in this conversation with Robert Proctor. In the 1930s and 40s, there was the Nazi science and there was communist science. And each had fundamentally different ideas about, for example, genetics and biology of disease. This history also shows that scientists can be corrupted slowly or quickly by fear, fame, money, or just the ideological narratives of a charismatic leader that convinces each scientist and the scientific community that their work matters for the greater cause of humanity. Even if that cause involves the genetic purification of a people, the extermination of a cancer and the unrestricted experimentation on the bodies of living beings who do not have a voice whose suffering will never be heard. All of this for the greater good. In some periods of human history, science was deeply influenced by the ideology of governments and individuals. In some less so. The hard truth is that we can't know for sure about which of the two periods we're living through today. So let us not too quickly dismiss the voices of experts and non experts alike that ask the simple question, question of wait. Are we doing the right thing here? Are we helping or hurting? Are we adding suffering to the world or are we alleviating it? Most such voices are nothing more than martyrs seeking fame, not truth. And they will be proven wrong but some may help prevent future atrocities and suffering at a global scale. Let us then move forward with humility so that history will remember this period as one of human flourishing and where science lived up to its highest ideal. This is the Lex Friedman podcast. To support it, please check out our sponsors in the description. And now, dear friends, here's Robert Proctor. What is the story of science and scientists during the rise of rule and fall of the Third Reich?

Well, we tend to think of science as always on the side of liberty, as always on the side of enlightenment, as always on the side of enlarging human possibility. And here we have this phenomenon in the 1930s of really the world's leading scientific power, the Third Reich, which collectively had won a big chunk of all the Nobel Prizes, suddenly they go fascist, they go Nazi with Hitler. And instead of being primarily a source of resistance, science in many respects actually is the full collaborator in the most horrific forms of Nazi genocide, Nazi exclusion. And that's kind of a relatively untold story in the sense that when we think of science in the Third Reich, we think of Joseph Mingeli injecting dye into the eyes of twins, or we think of horrific human experiments. And those are real. But it's also the story of a huge scientific apparatus, a bureaucracy, you could almost say, participating in every phase of the campaigns of Nazi destruction. And what I looked at in particular in actually my first book was how physicians in particular, but also biomedical science was collaborating with the regime. And that it's wrong to think of the Nazi regime as anti science. It's anti a particular type of science. In particular, it was radically against what they call Jewish science, Communist science. Certain types of science they did not like. There's a whole nature nurture dispute in that period. And they're firmly on the side of nature, which interestingly gives rise to a very different type of science in the Soviet Union.

By the way, the Soviet Union is more in the nurture side.

The Soviet Union is on the side of the nurture side in the dimension of genetics. And this is sort of an untold story. I was actually going to write a book about it until I was barred from access to the Soviet Union. There have been different times in my life where I was a Russianist.

A Russianist, okay, we're going to have to talk about that.

But I got excluded from fulfilling that dream. But one of the things I was going to look at when I got a fulbright in the 1980s was to go over and look at the anti Nazi genetics and anthropology of the Soviets and how A lot of their Lysenkoist Lamarckism was actually anti Nazi antigenetics on the nurture side of nature. And that's really an untold story. It's an uncomfortable story because it sounds like someone we might want to make heroes out of, the twisting of science in the Soviet Union. But nonetheless, there are these interesting complexities. And what's amazing about Nazi science is how there was this collaboration. And you're talking about a culture where they're inventing things like electron microscopy, they're doing all kinds of studies in anthropology. So a lot of that's an untold story.

So what was the connection between the ideology and the science, if you can just linger on it longer?

Well, we tend to think of science and ideology as completely separate, when I think the reality is they're not. If you look at why the Mayans in the 7th and 8th century AD had the world's most accurate calendar, accurate to within 17 seconds per year, that was all part of a ritual practice to celebrate the rise of Kukulkan, the rise of Venus, with what's called the heliacal rising, namely the rising of Venus before the rising of the sun.

At.

Which moment Venus is destroyed by the light of the sun. Well, they developed this elaborate calendrical astronomy, which required detailed observation, detailed chronicling of movement of the heavens, in particular the planets, for the purpose of celebrating this cycle of renewal that they thought was sacred and holy and magical. So where's the ideology? Where's the science? There's the sort of instrumentation, the calendrics, the measurement, all in the service of this magical moment. And I think that's true of a lot of science. I had a friend years ago who was Mennonite and wanted to study solar cells and to improve silicon chips to make more efficient solar energy. There was no money for that. When Ronald Reagan took office, the budgets for solar and alternative energy were essentially zeroed out. And Reagan takes off the solar panels off of the roof of the White House. So my friend ends up working on hardening silicon chips against nuclear war. So he becomes part of the nuclear war protection defense apparatus, even though he wanted to work on alternative energy, doing very similar work with silicon chips, but in a different framework. And so the practice of science often gets pushed into and is woven into ideological practices, sort of in the same way that you get beautiful medieval cathedrals built in service of Catholicism.

Well, what's in the mind of an individual scientist? So this process of ideology polluting science, or is it science empowering ideology? So almost like if we can zoom in and zoom out effortlessly into the individual mind of a scientist, then back to the whole scientific community. Do scientists think about nuclear war, about the atrocities committed by the Nazis, as they're helping on the minute details of the scientific process?

I think sometimes they do and sometimes they don't. Right. You think of the chemists working to develop the cyanide that will be used to kill Jews in a concentration camp. What are they thinking? You can imagine a whole range of thoughts. Maybe they don't know what they're doing. Maybe they do. Maybe they know a little bit, but not a lot. Maybe they don't want to know. Maybe they have ways of lying to themselves. Maybe they are the one person who agreed to do it and 99 refused. So, you know, it's hard, if not impossible, to know what's in the soul of anyone. But when you have enormous power directing the motion and the currents or the ocean, it's not hard to find people willing to fill that in, especially if they're narrow technocrats, if they're just doing their job, if they're just building the widget. And I think a lot of scientific training is in widget building. And that leads to the possibility that they can become easily instrumentalized in a particular action which is maybe horrific or glorious. The other thing to keep in mind is that science is, as we say, what scientists do. And that can include a lot of things. It can exclude a lot of things. The word science itself is interesting because it's cognate. It actually comes originally from the proto Indo European skein, meaning to cut or divide. And so it's cognate with scissors, schism, skin. Skin is that which divides you from the world. Shit or scat is that which has been divided from you into the world. And so there's this cognate between science and shit, or science and cutting, with the whole idea being that you're dividing into parts, classifying. It's the taxonomic impulse. And to know is to know where something belongs, to divide it into its parts and put it in its proper place. And that taxonomic impulse can be very static. It's actually one of the things that Darwin had to overcome in recognizing evolution, that the taxonomies are in motion. But it also can lead to a kind of myopia, that my job is done when I've classified something. Thing is this bird an X, a Y or a Z. And that, again, can be. It can be ideological or it cannot be. But scientists are humans, and they're fitting in with a World with a world practice. And that's limiting. It's kind of inevitable. It's unavoidable. It's hard to be, if not impossible, out of the world that we're walking in.

Yeah, and it's fascinating because I think ideologies also have an impulse towards forming taxonomies. And there is so, just. So being at mit, I've gotten to learn about this character named Jeffrey Epstein. I didn't know who this was until all the news broke out and so on. And it started to wonder how did all these people at MIT that I admire would hang out with this person just lightly just have conversations. I don't mean any of the bigger things, but even just basic conversations. And I think this has to do. You said scientists are widget builders and taxonomizers. I think there's power in somebody like the Nazi regime or like a Jeffrey Epstein. Just being excited about your widgets and making you feel like the widget serves a greater purpose in the world. And so it's not like you're, you know, some. Sometimes people say scientists want to make money and. Or they have a big kind of ideological drive behind it. I think there's just nice when the widgets you like building anyway, somehow somebody convinces you, some charismatic person that this widget is actually has a grander purpose. And you don't almost feel. Think about the negative or whether it's positive. Just the fact that it's grand is already super exciting.

Yeah, yeah, I think that's right. I think that's the story of Wernher von Braun, you know, and the fascination with rockets. And this will, you know, enlarge something in the world. And here he is, he's an SS officer, he's working around slave labor. But his rocket then gets compressed into the Western world or the American world and basically launches us to the moon and we forget about how the sausage was made originally.

Well, can you talk about him a little bit more because he's such a fascinating character. So he was a Nazi, but it was also an American. And it had such a grand impact on both. And there's this uncomfortable fact that he's one of the central figures that gave birth to the American space exploration efforts.

Yeah, he's an interesting figure, fascinated in a kind of a tunnel vision way with spaceflight. He makes these beautiful rockets already beginning in the 20s, early 30s, ends up for a while at Penamunda using slave labor to build V2 engines and so forth like that. I remember going to Peenemunde where people have actually Tracked the flights of aborted V2 rockets and found some of these beautiful, beautiful old engines, just the most like works of art. These engines used to rain terror on the British. It's interesting because in that same spot I was hunting for amber, Baltic amber, because I'm a stone collector. And among the amber collectors there, there's a famous story of the penimunda burn, it's called, because they find yellow phosphorus, they think it's amber, they put it in their pocket, and then it dries out and then explodes and creates this big burn on their legs. But the whole Nazi regime is full of things like that. It's full of these scholars who get twisted into a mindset. And it's also important to realize that people didn't often see what was coming. And we look back and we say, how could you X, Y or Z? But before the Holocaust, there's not the Holocaust. There are versions of it, but things get on a new meaning, gain a new meaning in light of subsequent events.

And there's an entire propaganda machine that makes it easier for you to hold the narrative in your head. Even if you kind of intuitively know there's something really wrong here because of the propaganda. You can kind of convince yourself to be able to sleep at night.

That's right. And we have to remember that Goebbels office was not the Office of Propaganda, it was the Office of Enlightenment, of popular Enlightenment and Propaganda. So Enlightenment, Enlightenment was part of his.

Just the new era of enlightenment. From his perspective, it was supposed to.

Be the new age, a new era of enlightenment. It's a little bit like the kind of myth of Hitler's failed artist. You know, his art is not that bad. You know, there are a lot of artists who are, who are worse. And I had a very interesting conversation once with my college roommate who became a librarian at Harvard. And at Harvard he met an old, old librarian, a German woman who had met Hitler as a kid when she was like 8 years old. Her dad was like a Gauleiter for the Nuremberg area. And she said that for 15 minutes Hitler goes out onto the balcony with her and has this conversation alone with this eight year old girl. And she said he was charming and funny, and then he said he loved kids. And she said he was the most charming sort of person. And that's part of the history too, that we tend to forget when we make a scarecrow image of this rabid, raging fanatic. You know, there's more to it than that.

That's really, really, really important to think about when we make a scarecrow because that gives you actionable. Like, it forces you to introspect about people in your own life or leaders in your life today, ones you admire. They're charismatic, they're friendly, they love kids, they talk about enlightenment. You have to kind of think, all right, am I being duped on certain things? You have to kind of have a. I mean, that's the problem with Jerry Epstein that people don't seem to talk about. I don't. I. I never met the guy, but just given the people he talked to, whom I know, it feels like he must have been charismatic.

Yeah.

Like, people think about, like, oh, it's because of the women, it's because of the money. I don't. The people I know, I don't think they're going to be influenced. Ultimately, it has to be how you are in the room and make. It's exactly like you said, the enlightenment. I think that excites the scientists. Of course, as a charismatic person, you have to know what to pick in terms of what excites you. But that is also the fascinating thing to me about Hitler is all of these meetings, even with Chamberlain inside rooms, whether he was screaming or whatever he was saying, it seems like he was very convincing. There must have been passion in his eyes, there must have been charisma. That one on one, in a quiet conversation, he was convincing.

Yes. There's a famous story about Goebbels who would do a party trick where for 15 minutes he would rouse the crowd to communism. Workers of the world, unite. Then for 15 minutes, he would rouse the world to capitalism and individualism. And then for 15 minutes, he would rouse the world to Nazism. And apparently he was quite convincing in each of those performances.

Well, all those ideologies are pretty powerful. I mean, they. And I think it's not even the reason that matters as much as the power of the dream of the vision of the enlightenment. I mean, the vision of communism is fascinatingly powerful.

Yeah.

Like, workers unite. The common people stand together. They'll overthrow the powerful, the greedy, and yet share the outcomes of our hard work.

Yeah. Well, it's kind of like the story of two thirds of the things that Marx calls for in the Communist Manifesto are already just part of the liberal state. And so the parts we remember or forget about an ideology are very revealing.

If we can just linger on this a little bit longer. What have you learned from this period of the 1930s about the scientific process? So one of the labels you can put on your work on you as a scholar, as A philosopher of science. And you also talk about Nazi Germany as a singular moment in time or like a rebirth of the integration between ideology and science. So, like, in terms of valueless science, I think is the term value free science, value free science that you use? I mean, it seems like Nazi Germany is a important moment in history. I mean, it probably goes up and down. What, what difficult truths have you learned about the scientific process and what, hopefully things have you learned about the scientific process?

Well, I guess the saddening thing is how easily people can become part of a machine. If there's power, people can be found to follow it. One of the things I work on is Big Tobacco, and we'll probably come to that. But it's amazing to me how easily people are willing to work for big Tobacco. It's amazing to me how many scientists and physicians were willing to work for the Nazi regime for multiple reasons. Partly because a lot of them really thought they were doing the Lord's work. They thought they were cleaning the world of filth. I mean, if you really thought Jews are a parasitic race, why wouldn't you, you know, get rid of them? So there's an ontology, there's. There's a theory of the world that they're building on. And interestingly, one that was also present in the United States. And one of the things I did find out in my earliest research was that the Nazis had looked lovingly and enviously over at the United States in terms of racial segregation, racial separation, and saw themselves in a kind of competition to become the world's racial leader as the most purified racial form. And that this required this kind of cleansing process. And the cleansing meant getting rid of the physically handicapped, getting rid of racial inferiors as they imagine them. It meant getting rid of cancer causing chemicals in the air and in our food and our water. These were all of a piece. There's a famous illustration that Richard Dahl talks about, the great cancer theorist of studying in Nazi Germany in the 1930s. And he's shown a lecture where cancer cells are shown as Jews and X rays are shown as storm troopers, and these stormtroopers are killing the cancer cells who are also Jews. And so there's this metaphorical work of cleaning, extermination, sanitation, purification of a sort, purification. There's definitely a kind of purity quest. And you see that at multiple levels. And so you see how easy it is for people to fall into that given a particular theory. And again, coming back to that earlier sort of point about the scarecrow, which I think is Very important. If we imagine that nothing like this went on here in the United States, that would be a big mistake. The Nazis are looking to the Save the Redwoods League, to their, you know, to the Aryan supremacists, to the Ku Klux Klan, to the. To the separation of blacks and whites. Blacks were not allowed to join the American Medical association until after World War II. So you have racial segregation, you have massive sterilization in the United States way before the Nazis. One of the first things the Nazis do, from a racial hygiene point of view, is start sterilizing what they call the mentally ill and the physically handicapped. Well, that had been going on since around World War I in the United States and even earlier in certain states in the form of castration of prisoners in order to prevent their demon seed from being propagated further into the race. So there's a kind of a racial Internationale that's going on, and that part of the story also needs to be told.

And scientists were able to carry those ideas in their mind from your work.

Of course. Of course. I mean, that's one of the things going on with all the renaming of buildings now is scientists who were eugenicists are now getting their names pulled off of buildings. My personal view is that it has to be done on a case by case basis. But in general, I think it's usually better to add on rather than subtract. In other words, to add history rather than erase history or pretend as if history had never existed. Let me give you a specific example of that. One of the most powerful and diabolical university presidents in the Nazi period was a guy named Carl Astel, A S T E L. And he was a rabid Nazi high up in the leadership. And in his portrait at the University of Vienna, there he is in full SS uniform. That painting was taken down. Now what I would have done is left the painting and put a, you know, add a plaque.

Yeah.

But to pretend as if that never happened or to erase history in that way, I think is. Is a big, big mistake.

Kind of linger on that point. So I haven't gotten through it yet, but I've been trying to get to Minecamp and, you know, throughout its history has been taken down and up. It actually was taken down from Amazon for a while recently. What can you say about keeping that stuff up? So the reason it was taken down from Amazon, I mean, there's. There's a large number of people that will read that and the hate in their heart will grow. So they're not using it for educational Purposes, you can't put a plaque on the Mein Kampf. You're ruining Mein Kampf then. Like you can't. I mean, this is, you know, Amazon can't do a warning saying like you.

Could do expurgated version of Mind Copy, take out the word Jew, you know.

Exactly.

That would.

Exactly. So it still just stands on its own. Yeah, I mean, it's not well written. So you can maybe convince yourself that it's okay because it's not well written. So it's not, it's not like this inspiring book of ideology that could easily convince. But can you steal man the argument that minecom should be banned and can you steel man the argument that it should be not banned?

Well, I wouldn't say it should be banned. I think if anything, that might make it forbidden fruit. Now this might be different. When we come to statues on the public square after World War II, the statues of Hitler, there must have been thousands of them were taken down. Now I think even the most rabid opponents of cancel culture would not say there was something wrong with taking down the statues of Hitler that were in every office building, every post office. So I think a lot depends on the placement and the purpose of icons, of statues, of text. I don't see the harm in being able to buy Mein Kampf. It's so out of this world by now. Just the language. And if anything, there probably is more good done by people being shocked at how dumb it is than the evil that might be done by someone reading it. I can't imagine people being really gripped by that now, partly just because it's kind of outdated and crazy, crazy talk. So in that case, I would not be in favor of that. When it comes to monuments or other types of things, it's a judgment call in each case. I think it has to be probably voted on. But it also, I think in many of these cases there's an add on view would fix a lot of the problems.

We'll jump around a little bit. We'll come back to medicine and war on cancer.

Let me just add one thing on that. Recently the the name of Macmillan who works on the charge of the electron. In early part of the 20th century, his name was taken off of a building at Caltech. Well, to take his name off, what do you really do? It wasn't a central aspect of his actual work. It's not why he was put on the name of that building at Caltech. And also the memory is lost and the lesson is lost when you could have kept the macmillan name on the building and added a plaque. This guy was a racist or this guy was a eugenicist or something to make a teaching moment instead of just a forgetting moment.

Yeah. Well, let me take a small tangent and ask you about censorship and this particular period we're living through. So my friend Joe Rogan has a podcast. He hosts a few folks on there, and they're folks of differing opinions. And as we speak, there's kind of a battle going on over whether Joe Rogan should be on Spotify and allowed to spread scientific misinformation. In particular, there's a guy named Robert Malone that's talking about. That's making a case against, at least against the COVID vaccine and so on. So outside of the specifics of this person, in this battle of scientific ideas that are sometimes tied up with ideology in our modern world, what do you think is the role? Like who gets the censor decide what is misinformation or information? Should we let ideas fly in the scientific realm? So scientific ideas, or should we try to get it under control which way? Obviously, all approaches will go wrong in some ways. Which is more likely to go wrong? One where you try to get a hold of like, all right, this is a viral thing and it doesn't fit with scientific consensus, so we should probably try to quiet it down a little bit. Or do you let it all just fly and let the ideas battle? Do you think about this kind of stuff in the context of history?

Well, that used to be a million dollar question. Of course, now it's a multi billion dollar question, not trillion. Yeah, we're talking about powerful Internet platforms becoming essentially publishers. And publishers can't say whatever they want. There are limits. They can't yell fire in a crowded theater. But there's a kind of social responsibility that is there. And I know some of these. I don't know a lot about this topic, but I know there are large. Some of the large platforms do have dedicated offices to trying to rein in misinformation, as you would expect any publisher to do. You can't just let anything fly in Time magazine or the New York Times either. There are all kinds of codes of ethics and legal obligations. So I'm a fan of the efforts or I think some of the large Internet platforms should be congratulated, at least for trying to. To make an effort to rein in misinformation. It's going to be difficult and mistakes are going to be made, but it can't be a let everything fly kind of situation.

But when I watch, unfortunately, the pressure these platforms feel to identify and to censor misinformation. That pressure is ideological in nature currently. So if you just objectively look, there's a certain political lean to people that are pressing on the censorship, on the misinformation, which makes me very uncomfortable because now there's an ideology to labeling something as misinformation as opposed to kind of having a, you know, value less evaluation of what is true or not. And you also have to acknowledge that it says something, that there's a very large number of people that, for example, follow Robert Malone or follow people. I mean, what does that say about society? And there's a deeper lesson in there that's not just about blocking misinformation. It's distrust in science and institutions, distrust in leadership. Like, it feels like you have to fix that. And then censorship of misinformation is not going to be fixing that. It's only going to, like, throw gasoline on the fire. You got to put out the fire.

Well, that's certainly possible. Yeah. I mean, I think people are distrustful of certain institutions and not others. Right. And I think a lot of distrust is good. I'm not a conspiracy theorist, but I do know there have been a lot of conspiracies and that people work behind scenes to do powerful bad things, and that's what needs to be exposed. The other thing I worry about, which is relevant to your question, again, it's a billion or a trillion dollar question, is I think in a world of kind of flattening, where all news or all information or all data is kind of equal in some way, and so you get the Twitterverse going and doesn't matter if it's peer reviewed or it doesn't matter if it's been supported by evidence. It's just a kind of outburst. It's interesting to contrast it with, say, 100 years ago. I mean, what would a crazy person or a flat Earther or anything, what venue would they have? I mean, maybe they could go to a church or someplace. I mean, so now we have these empowering engines. Then that's what's new historically, is that basically anyone can have a blog or a Twitter feed. And that is new. And so that is, you can think of it also as a kind of clutter. So it's a kind of a radical democracy in a way. Kind of the. One of the weaknesses of democracy is if everyone has an equal voice and if everyone has equal power.

So there's, of course, a flip side to that, where everyone has equal power. It forces the People who are, quote, unquote, experts to be better at communication. I think people like scientists are just like upset that they have to do like better work at communicating. Now they used to be lazy and you can just like say, I have a PhD, therefore everyone listen to me. Now they have to actually convince people, like you have to convince people that the earth is round. You can't just say the earth is round. That's it. You have to like show. You have to make like, I mean, not the earth is round part, but things like that. You have to actually be a great communicator, great. Do great lectures, do documentaries and so on, and to battle those ideas and then also to defend the sort of the people labeled as crazy. You know, in Nazi Germany, if you were protesting against some of the uses of science, of medicine to commit atrocities, you would also be labeled crazy. Yeah, well, those sources are important.

Yeah. There's so many good points there on the scientists becoming good communicators. The history of scientists becoming bad communicators has a history. And the last original contribution to science, written entirely in the form of a poem is Buffon's Loves of the Plants. And following that, in the 18th century, you get the uglification of science, the deliberate uglification of science. With the idea being that if you are clear and if you speak beautifully, if you write beautifully, you're hiding something. You're covering over the truth with flowers and decorations and scents and pleasant odors. And so you get this scientific paper format, introduction, discussion, methods, results, conclusions. And it's kind of policed in this inhumane, non humanistic kind of rhetorical way. And that's a big problem. And so you get that combined with just the rise of the research lab and the ever narrower widget builders, the cogs in the machine, it's not surprising that people might not trust certain aspects of that. That combined with the dirty laundry history of a lot of science, that you did have the requirement at Auschwitz that people be that physicians supervise the killings, you know, the horrors of, you know, Tuskegee and all kinds of other things, or even something like the atom bomb, which is arguably more neutral at least, but nonetheless horrific. And so it's not surprising that a lot of people don't trust science. And a lot of science shouldn't be trusted. Right? There's science and then there's science. So there's a long history of dirty, bad science that you don't solve just by saying we should have trusted it.

Let's just stay on Covid for a brief moment and talk about a particular leader that I think about as Anthony Fauci. I've thought about whether to talk to him or not. I have my own feelings about Anthony Fauci, by the way. I'm, you know, I admire basically everybody and I admire scientists a lot. And there's something about him that bothers me, I think, because I'm always bothered by ego and lack of humility. And I sense that maybe, maybe I'm very wrong on this. But so he said that he represents science. If you've taken him full context, I understand the point he's making, which is, you know, when people attack, Attack him, they think of him as representing science, things like that. But there's ego in that. And what do you think motivates and informs his decisions? Is it politics or science? And the broader question I have, what does it take to be a great scientific leader in difficult times like these? And maybe you could say Nazi Germany was similar. When there's obviously, like you, Anthony Fauci, just like scientific leaders during Nazi Germany could have made a difference, it feels like positive and negative. And so it's like there's a lot of stake. There's a lot of stake in terms of scientific leadership. If I've asked about 17 questions, if there's something worthwhile answering in that, well.

Fauci, I think, is doing as good a job as he can. I mean, you can't turn on the television without seeing him.

Well, no, that's what's the goal of the job. That means he appears a lot, but he does not come off as somebody with authenticity. Like, I admire so many science communicators, about 10x100x more than him, including his boss, Francis Collins, who have I recently lost respect for, given some of the emails that leaked. There's ego in those emails.

Yeah.

And it upsets me because, like, I hope all that stuff comes out and wakes young scientists up to. Don't be a douchebag, don't. Don't be humble, be honest, be authentic, be real. Put yourself out there. Don't play the PR game, don't play politics. Just get excited about the widget building that you love. Communicate that and think about the difficult ethical questions there and communicate them. Be transparent. Don't think like the public. Don't talk down to the public. Don't think the public is too dumb to understand the complexities involved. Because the moment you start to think that when you're like 30, what do you think happens when you're 40 and 50? The slippery slope of that, the ego builds, the. The dis like this, the distaste for the public opinion builds and then you get into the leadership position at the time you're 60 and 70 and then you're just a dick and you're a bad communicator to the very public. So I think this is something that just builds over time is the skill to communicate, to be honest, to be real, to constantly humble yourself, to surround yourself with people that humble you. Anyway, I'm bothered by it because I feel like science is under attack. People distrust science more and more and more.

Yeah.

And it is perhaps unfair to put place like Anthony Fauci to blame for that. But you know what? Leaders take care of the responsibility. So in you saying that he's doing the best job he can, I would say he's doing a reasonable job, but not the best job he can.

Yeah, well, I don't know what his capabilities are on that.

I mean like the other.

Right.

Like what? Like you can imagine how history sees great leaders that unite on which history turns. That's not a great leader because there's a huge division, that there's a lot of people. There's a lot of people in leadership position that can heal the division. You could think of tech leaders. They can heal the division because they have the platform. They can speak out with eloquence. You can think of political leaders, presidents that can speak out and heal the division. You could think of scientific leaders like Anthony Fauci. They could heal division. None of these are doing a good job right now. Leadership is hard, which is why when great leaders come along, history remembers them. So I just want to point out the emperor has no clothes when the leaders are like eh, kind of mediocre because it feels like. I guess I'll take it to a question about Nazi Germany. What is the heroic action for Scientists in Nazi Germany like to stand to see what's right when you're under this cloud of ideology.

Yeah. Well, it's an almost impossible task in Nazi Germany. Maybe the heroic task would have been before Hitler was essentially elected and the Reichstag is burned.

So in the 30s, I guess that's building.

When it's building what the other alternatives are. Maybe it's events in World War I that that could have made Nazism less inevitable. Maybe it's going back to the British Empire which had a giant empire and Germany wanted a big empire too. And that part of the history of World War I is often forgotten. So the heroic act is to stand up and tell the truth and fight against evil.

And of course you get outside to.

Interrupt, but of course you have some courage.

You know, but I also, so I, I personally don't always have complete respect of people who stand up and have courage because it's not often effective. What I, what I have the most respect for is long term courage. Like, that's effective because like, you know, if you're just an activist and you speak out, this is wrong, that's not going to be effective. Because everybody around you is saying, nah, it's like we like our widgets. Yeah. So you have to somehow like steer this Titanic ship.

Yeah.

And I guess you're right. The easiest way to steer is to do it earlier.

Well, everyone has different skills. You know, Musk is building electric cars and other people are trying to, you know, build solar and wind. And there are all kinds of problems that we're going to solve. Right. People are building better vaccines. There's a thousand ways to do good in the world and a thousand ways to do bad in the world. I mean, part of the problem in science is that we don't look enough at what I call the causes of causes. So cigarettes cause cancer, but what causes cigarettes?

Yeah, so the deeper.

Yeah, so obesity causes heart disease, but what causes obesity? And it's not just gluttony and sloth, it's the decision to pump up the sugar industry and to allow soda in school. And I'm a big fan of what I call loop closing. We're all worried about climate change and reducing our carbon footprint, but what about the hidden causes, the unprobed causes? I'm doing a project now with Londa Schiebinger on looking at how voluntary family planning could actually have a big role in reducing carbon footprint throughout the world. And these literatures are never joined or rarely joined, that we have this huge carbon emissions problem, but we also have too many people on the planet and the cause of that is because too few women and men have access to birth control. And if you join those realms open, there's going to be new possibilities. And it's kind of like looking at the flip side of fascism and the kind of things, discoveries they made that have been ignored. That's one of the things I'm interested in, is finding some of the gaping holes, the ideological gaps that have been ignored because of ideology. Left or right, by the way.

Both.

Of which involve blinders. And so there's all kinds of blinders that we live in. That's part of ideology, is what don't.

We even see and that would prevent us from seeing some deep, objective, scientific truth.

Right? Some truth.

And there's actually just to mention there's some people, including Elon, who are saying there's not too many people, there's not enough people. Right. That if you just look at the birth rates. And so it's like some of this is actually very difficult to figure out because there's these narratives. You mentioned tobacco, obesity with sugar. There's been narratives throughout the history, and it's very. There are certain topics on which it's easy to almost become apathetic because, like, you just see in history how narratives take hold and fade away. You know, people were really sure what that tobacco is not at all a problem. And then it fades, and then they figure it out. And then other things come along. What other things came along? Now, you know.

Well, you asked about ideology, and one of the things I always ask students before class, whether I'm teaching agnotology or world history of sciences, what makes fish move? And 90% of Americans will say some version of muscles, fins, know, neurons, when the reality is, at least in salt water, fish don't swim places. They're moved by currents. Fish are moved by currents. That's what makes fish move. This is not even counting the rotation of the Earth on its axis or the rotation of the Earth around the sun or the rotation of the solar system around the galaxy. You know, ignore all that. Even on Earth, fish arrive up in Alaska. They don't swim there. They come by currents. And this is known to people who understand the ecology of fish. But we, as sort of individualistic Americans.

Think that the fish pulled itself up by his bootstraps.

Pulled itself up by its bootstraps, Right? And whatever, you know, gumption and courage, you know, made his own world. Instead of thinking of something like cigarettes, for example, hitting a village like an epidemic, hitting the village like cholera or pneumonia or something like that. So there's a big ideology we have of personal choice. A great example of that is in the tobacco world, where people always. There's a whole field called cessation. That always means cessation of consumption, never cessation of production. All blame is put on the individual smoker instead of looking at how they get smoked. And looking at that bigger picture, I think is part of the story.

So a few years ago, you wrote that the cigarette is the deadliest object in the history of human civilization. Cigarettes kill about 6 million people every year, a number that will grow before it shrinks. Smoking in the 20th century killed 100 million people. And a billion could perish in our century unless we reverse the course. Can you explain this idea that it's the deadliest object in the history of human civilization? Maybe just also talk about big tobacco and your efforts there.

Well, cigarettes have killed more than any other object, than all the world of iron, all the world of gunpowder. Nuclear bombs have only killed a few hundred thousand people. Cigarettes have killed hundreds of millions. And every year kill about as many as Covid. They're sort of neck and neck. But if you took the last five years, there's no contest. Cigarettes have killed far more and are far more preventable. So what, we're in a world, this bizarro world, where every night there's a Covid report and cigarettes would never be mentioned. Cigarettes would know more likely to be mentioned than if we were talking about chewing gum on a sidewalk. They'd be no more likely to be in a presidential debate than, you know, sneezing in the wrong place. So we live in this world where most things are invisible. You know, we are. The eyes are in the front of the head. We don't see what's behind us. We have a fovea, which means not only do we only see what's in front of us, we see in a very narrow tunnel. And that's because we're predators. We don't have the eternal watchfulness of prey. We have a zeroed targeted focus. And that leads to a kind of myopia or a tunnel vision and all kinds of things. Then when you get something like a very powerful tobacco industry, which is a multi, multi billion dollar industry, which still spends many billions of dollars advertising every year, but nonetheless manages to make themselves invisible. You have this powerful agent that is producing, producing this engine of death that is invisible. It's been reduced to the fish that move themselves. In other words, there's not really a tobacco industry. There's just people who smoke. And that's a personal choice, like what food we're going to have for dinner tonight. And so it's erased from the policy world. It's as if it doesn't exist. And creating that sense of invisibility to failure to understand the causes of causes is what allows the epidemic to continue, but also not even to be acknowledged.

How's the invisibility created? Is it natural? Is it just human nature that ideas just fade from our attention? Or is it malevolent still going on kind of action by the tobacco companies to keep this invisible?

It's still going on. Even when you see an ad against cigarettes on television. That's dramatically curtailed because the law that made those even possible required that there be. There's an anti villainy clause. The industry can't be made even visible in those ads. In some they get away with it. But the industry operates through very powerful agents, you know, powerful senators. They used to count three quarters of the members of Congress as grade A contacts. They had most of the senators in their pocket. A lot of the senators. Sometimes they'll play both sides of the aisle. Basically tobacco is Democratic Democratic Party until basically the 70s and Ronald Reagan. Then it shifts over to becoming Republican. They create bodies like the Tea Party. They merge with big oil, the Koch brothers in the 1980s and 90s to form the Tea Party. And a whole series of fronts which fight against all regulation and all taxation in order to prevent gas taxes and cigarette taxes which are bonded in the convenience store and Walmart. Most cigarettes are actually sold in places like Walmart and pharmacies and Seven Elevens, things like that. And through that locus then you have gasoline and tobacco sort of in this microarchitectural collaboration. So there's multiple, multiple means that they use. Plus a lot of their targeting is hyper specific. They use the Internet very effectively. They use email that are customer targeting.

What goes to the mind of a big tobacco executive. This is connecting to our previous conversations of scientists and so on. I always wonder about that. I talked to Pfizer CEO for example and there's a deep question with the Pfizer CEO with I guess any CEO but Big Pharma, would you. It's like if you can come up with a cure that gets rid of the problem that's in the big Pharma, would you want to? Because you're going to lose a lot of money once the cure fixes the problem. It's nice to like there's so many incentives to make money. Can you think clearly and make the right decisions? I'd like to believe most people are good. And it's almost like this Steve Jobs idea. Just like do the right thing and you'll make money in the end. It's like long term you'll make a lot of money if you do the right action. Because there's always going to be problems you can fix. You can always pivot the company to focus on other things. As long as you're doing the best innovation, the best science, the best development and the, the production and deployment and stuff, you're going to win. But there's another view where you might that kind of idea of making money pollutes you. It's the widget building. It's exciting when you can release a product that makes a lot of money and you start enjoying the charts that say the money's going up and you stop thinking about maybe there's the. This. That's the wrong choice for human civilization.

Well, one of the reasons I was made a. A courtesy appointment in pulmonary medicine at Stanford was they recognized I was doing more to save lives by trying to stop Big Tobacco than they were by yanking out this lung, that lung on a daily basis.

Cause of causes.

The cause of causes, which we can keep returning to. Your question about how do people live with themselves is a crucial one, and it's one I've thought about a lot. It's one you think about with in any context of horror. How do people live with themselves? How do they get up in the morning? I think there's a lot of incentives. One thing that you have to keep in mind is that whoever becomes CEO of a big tobacco company, they have already made decisions along the way. And they are the remnant of a whole series of aspiring people who want to climb the ladder of success. Who maybe would refuse something like this.

But those don't survive the journey.

Those survive the journey. Who can make it through. And I think they have a mixture of ideologies. One they'll say, well, if I didn't do it, someone else would. This is kind of the Pour the Cyclone bee down the chimney into Auschwitz. Well, if I didn't do it, someone else would. So what's really the difference between me doing it and someone else? So that's one view. Another one is the tobacco industry, I think, really doesn't like their customers, except for the fact that they like their money. When you look at their documents, they talk about targeting against young adults or against women or against homosexuals. There's a whole project Reynolds has called Project Scum, which is Project Subculture. Urban markets where they're targeting homeless and homosexuals in San Francisco. So what kind of business model regards their customers as scum or talks about them as one famous Reynolds executives. You know, we don't smoke this stuff. We reserve that for the poor, the black and the stupid. That's a direct quote from one of the Winston models.

So it's a company culture that sees the customers almost like as the enemy or worthless losers. Losers.

So you have these executives, if we don't do it, someone else will. If people are dumb enough to buy our product, let them buy it. Maybe it's a personal choice. Maybe they're libertarians, maybe they're just, as you said, seduced by the money. And the money is enormous. The money is enormous and tobacco executives make tens of millions of dollars per year just in their salaries. So I think there's a whole series of logics. At some point, some of the companies have become food producers. In the 1980s and 90s, Philip Morris, which makes Marlboro, was the largest food producer in the United States. And so they could say, well, we're producing many products, many addictive, desirable products. I think one project I'm working on now actually is looking at how the industry maintains morale in their own workforce. And they create a kind of parallel world of prizes and rewards and tobacco queens and tobacco princesses and tobacco sports teams and tobacco. It's this whole separate world, a world within a world, and we all live in bubbles of a sort. And so there is this kind of tobacco world where you're with us or you're against us. And I even found evidence that the tobacco industry lies to its own employees. So they censored their own employee information so that everyone would be on board that, well, maybe it doesn't really cause cancer. The evidence is all statistics. Can't trust mice experiments because mice are not men. They hire the guy, Darrell Huff, who wrote how to Lie with Statistics, the best selling statistics book in the history of the world. They paid him to write a book called how to Lie about Smoking with Statistics that was never published when sort of word of some other dirty tricks got out. So one way they're able to gain legitimacy, gain normalcy, gain. You know, these are supporters of the arts. You know, there are universities named for tobacco executives. You know, we have Duke University, we have the George Weissman School, I think is of arts and sciences at cuny. And there are prizes. You know, Philip Morris essentially created women's tennis as a spectator sport. Billie Jean King joins the board of directors of Philip Morris. She signs coupons, two to one coupons for buying Virginia Slim cigarettes. So the industry is able to acquire this talent and then through a kind of an application of causality purely into the individual smoker. If you smoke, you did it to yourself. And so in a sense we have nothing to do with it. It's sort of the same argument Exxon is making now with carbon. It's like, well, we just make the gas, we don't burn the gas. So really we're not the problem. It's whoever drove here in a car that burned gas. And so there's a very interesting question, who is liable who is responsible for. Is the manufacturer just immune because it's a legal product and people make the foolish decision to smoke? Or does the addiction play a role in the liability? So these are all really interesting legal questions and philosophical questions.

Where do you attribute the success in the fight against big tobacco? So, I mean, there's been a lot of progress made. Maybe two questions. One is that, and two, how much more is to be done?

Well, there's been, in my view, not that much progress. The tobacco industry basically won the war against cigarettes in the 1950s. The broader assumption inside and outside the industry would be was that if tobacco, if cigarettes are ever shown as causing cancer, obviously they'll be banned. The famous slogan in the 50s was, if spinach were ever shown to cause one tenth the harm of cigarettes, it would be banned overnight. Flash forward 50 years. We still have 300. We still have 200 some billion cigarettes smoked in the United States every year. Globally, we still have about 6 trillion cigarettes smoked every year. That's 350 million miles of cigarettes smoked every year. That's enough to make a continuous chain of cigarettes from the earth to the sun and back with enough leftover for several round trips to Mars.

But it's much fewer than before. Okay, so culturally speaking, I grew up in Soviet Union. Everybody smoked. Everybody smoked.

Well, by everybody, you mean about half.

Well, by everybody. I mean culturally. So what does it feel like when everybody smokes? Right. What percentage is that right now in the United States? It feels like nobody smokes. Feel. I'm talking about culturally. Do you see famous actors and actresses? Do you see movies all the time?

You do. You can't watch a Hollywood movie without saying pretty much continuous smoking. I mean, look at Peaky Blinders. Look at any of the modern series now. It's pretty much a nonstop. You're right. There has been a change. I mean, that's true. The purest metric in the United States is number of cigarettes smoked per year, and that peaks in 1981 at 640 billion cigarettes.

Wow.

That's declined now to the level it was in 1940, which is about 240 billion cigarettes. Wow. Now, globally, the number has increased.

But the perception. Sorry to interrupt, but that's interesting. Even in the United States, the numbers. The decrease is not as significant as I thought it is because just in my own experience with people, you know, people speak negatively about smoking.

Yeah. Well, for one thing, smokers do. I mean, smokers hate the fact they smoke.

Right, Right. So this. This is the interesting observation I'm speaking to, is Even the smokers are talking negatively about smoking, but they're still smoking. So even though I'm seeing this shift where smoking is no longer the cool thing, where it's like, when I was growing up and I smoked for a time, it was like a way to bond with strangers, to. To talk, share a moment, share a moment together. I mean, it's a beautiful thing. And it. It's. It's interesting because we need to find other ways to share moments. But, you know, you bummer. You almost smoke from a stranger. I mean, that was seen as a good thing.

Now, did you ever smoke? Oh, you did for how many years?

Two years. I was a music. So what happened is I was a musician. I was in a band.

Well, there you go.

And no, there is a bonding aspect to it. And I think I stopped smoking when they banned smoking inside bars.

Yeah, exactly.

Which was. I mean, that was. I mean, looking back now, it seems it's such a powerful move. I mean, maybe you can speak to that, because that, that was one of the moments that woke me up. Wait a minute. Like, that was a big shift for me. And I'm sure I'm not alone. Where it's not just like it forced me to rethink the. The effect of smoking has on me.

Yes.

And also to think, can I actually live a life without smoking? Can I? You know, some people have that. I haven't. I haven't gone through that process yet, but some people have that with drinking.

Yeah.

Can I have fun without drinking? I think the answer to that is yes, but I'm still drinking. So that's a big shift. For example, if they ban drinking at certain places, and there's a lot of negative things to say about alcohol.

Well, I'm older than you, and I remember when mother and I think you weren't even in this country then, but there was something called Mothers Against Drunk Driving. And if you look at movies from the 50s, 60s, even 70s, being drunk was just kind of a funny thing. And you would drive drunk. What's the big deal, really? And Mothers Against Drunk Driving really denormalized drinking and driving, much like seatbelts. When I was a kid, there were no seatbelts. You just lie in the back of the car and you drove out west with your parents and you'd lie flat, and it was wonderful. Seatbelts come along. And now it's pretty normalized that you buckle up. It's pretty normalized that you don't drink. And so the moment you identify is absolutely, crucially important. A Lot of it started in California, where there were bans on cigarettes. Some of it actually started in the computer industry because some of the early bugs that were found on tapes in the 70s were caused by smoke. And some of the earliest indoor smoking bans were actually in computer rooms which were supposed to be clean enough that the tapes wouldn't spin and get caught by some snag of soot. And the workers started saying, wait a minute, if the smoke can hurt the tapes, can it hurt my lungs as well? And so some of these early laws, already in the late 70s, early 80s, pushing it out, it was a huge struggle. The tobacco industry marshaled an army of experts to say that secondhand smoke is an entirely different kind of smoke. It can't hurt you. They eventually lost that battle. And now we have so called smoke free laws where you can't smoke in most workplaces and most restaurants. And that denormalization has been crucial because remember Aristotle says, tell me who you walk with and I'll tell you who you are. And if your friends are smoking, if your friends are doing whatever, it makes it easier. The tobacco industry has been a genius at manipulating and really creating the material culture of the modern world. If your shirt has a pocket, that's to fit cigarettes, right? If your car has a plug in every car that I used to have had a cigarette lighter, it had an ashtray. Every plane that I flew when I was a kid, when I was younger, anyway, there was smoking on it originally, and then there were ashtrays. And even today, every plane, by law, has to have ashtrays in the bathrooms because people still smoke in the planes. There's a special technique they have where they go in and light up your cigarette and put your mouth right down in the middle of the toilet and then flush it right at that same moment. And that's why they're take a good big puff, take a good big puff and flush it. And to prevent people from bringing down the plane by putting the cigarette out in the trash, every plane must have ashtrays. So that tells you something about the power of addiction, the power of normalcy. And it's related to your question of this crucial moment. If you can no longer smoke in a bar, if you can no longer smoke. And by the way, that's different from drinking. Most people who smoke wish they didn't. Most people who drink, that's not true. Most people who drink, they don't wish. There are some addicts, 5%, we say, but you're talking about 70, 80, 90% of people who smoke cigarettes regularly wish they did not. And that's actually where I learned about the idea that we could get rid of cigarettes entirely was just from talking to ordinary smokers. Those are the people who are willing to say, you know, let's get cigarettes all together and get rid of them all together. Because it's not a recreational drug. It's very different from alcohol. And the genius of the tobacco industry has to turn basic, to trivialize addiction into just something we all like. It's addictive. I like it. And also to say that basically smoking is like drinking, which in fact it's not. Alcohol tends to be a recreational drug and cigarettes are more like heroin.

So how do we get that 200 billion down? Closer to zero.

Well, the good news, and I know you like good news, and I do too, is that every year we have about 8 billion fewer cigarettes smoked in the United States. So we're going in the right direction. We're going to solve this. Not every problem you can solve in the world. This is a very solvable problem. It's an enormous problem, arguably as big as Covid in certain respects, much more invisible than Covid, but very solvable and actually will be solved probably because of climate change, because we're going to need to find ways to reduce carbon footprints across the board. And that's going to be a kind of cultural revolution of sorts once we have a Category 6 hurricane and hundreds of thousands of people start dying from the storms that are coming. But it's like that metaphor of there's a sci fi film from 1950 where they're trying to get back to Earth from the moon and they have to jettison their toolbox and their ladder and this and this and this. That's sort of, I think, what the world we're going to be in. We're going to have to jettison a lot of things and cigarettes will be one of the things we can get rid of.

Let's come back to Nazi Germany for a time. You also wrote the book titled the Nazi War on Cancer, right? What is the main storyline and thesis of this book?

Well, I had been researching Nazi medicine. I went over to Germany. I didn't know what I wanted to do. I got a Fulbright. I originally wanted to go to Russia, went to Germany partly because my girlfriend was going there, Londa Schiebinger, and I was quick with the language. And my old landlady was born in 1900 and I was renting a room, a tiny room in Berlin, and she told me she had been a nurse in World War I and told me how sad it was that all the mentally ill had died in that war and that how the same thing happened in World War II. And she told me about how sad it was that she'd never gotten married because there were no German men around after World War I. But I also started taking classes in Germany. And at that time, there were still a few old Nazi professors just about to retire, you know, very old. And I remember there was one guy who would talk about the impact on ovaries of women exposed to stress and how this would damage their ovaries, and that this was like people who'd been told they were about to be executed and they would do a before and an after on these ovaries. One of these horrific experiments. This was a physician in Berlin. And so I got involved with a group of people and really, as a kind of intellectual garlic for living in Berlin. This is in 1980, 81. I started reading medical journals from the Nazi period. And even the librarians didn't like that. I remember the Preussis Staatsbibliothe in downtown Berlin. They're like, why do you want to. You know, you're not supposed to be reading these old Nazi journals. These are just medical journals, hundreds and hundreds of journals. And I just read them and read them and read them and read them and looking for details. I'd find, like, a veterinary medicine journal that would have a joking section where they'd say, oh, we found a cow with a swastika on its forehead, a natural black swastika. Isn't that funny? Or I'd find stories about tobacco. I find stories about abortion. I'd find stories about excluding Jewish medicine or Jews from medicine, or who's been promoted, who's been demoted, who's been Nazified. I discovered there was an entire Nazi physicians league that was just the top Nazi, the most Nazi of the physicians. I discovered that physicians joined the Nazi Party in a higher proportion than any other profession, that they joined the SS in a higher proportion than any other profession.

Why is that? Do you have a sense?

Because the Nazi regime is a kind of sanitary utopia. It was to create this purified world that would control the mind and fertility. So gynecologists and psychiatrists were the top. They were the most Nazified of the various medical professions. Control the body through sterilization, abortion. Control the mind through psychiatry. They killed a lot of the mentally ill. And you can read their professional journals. And I'm not sure these had ever been read since. I also went to East Germany because, remember, this is way before the wall fell. And they had a very special collection of taboo literature. It's kind of your point about should Mein Kampf be read? Well, of course, in East Germany, nowhere close, right? But not only that, Time magazine couldn't be read and Newsweek couldn't be read. And this file, this chamber that the foreign scholars were allowed to look through had all of the old Nazi literature and Nazi scientific literature and Time magazine and Newsweek and a whole pornography section as well. So all of the taboo topics. So here I'm researching in the West, I'm researching these topics the librarians didn't even want me to look at in the East. I was sort of going over there, I would hitchhike over there and overstay my welcome and, and things like that. But in any event, I noticed that there was this kind of taboo of talking about the big eugenics. I'd already been as a kind of a radical graduate student at Harvard, working with all the Marxist biologists there. We'd already had a critique of eugenics and women being excluded from science and South African apartheid was a big deal. And Arthur Jensen's blacks have lower IQs. So there was a whole nest of controversial hot topics around sociobiology, around race and iq, around women and scholarship and so forth. But we weren't looking at Nazi medicine. So I thought, I'll look at the big eugenics, not just this smaller stuff. Only 50,000 people are sterilized in.

In.

California, but there were huge numbers sterilized in Nazi Germany. So the more I looked into that, I realized there was a book there. But I had also started noticing this other weird stuff. Why were they anti tobacco? Why were the Nazis the first to recognize asbestos as causing mesothelioma? Why did they try to ban food dyes? Why are they the first culture in the world to encourage women to do breast self exams? I told my mom this, and she told me that in the 50s, women weren't even supposed to touch their breasts in Texas. And here in Nazi Germany you've got these mandatory breast self exams. Way before this was done in the United States you had the first laws banning the X raying of pregnant women. Already in the early 1930s, it was standard medical practice. They recognized that this could harm the fetus, harm the race. Way before radiation was recognized as a hazard in England or America, I started noticing these things. And I have an eye for oddities. I like the weird, the contradictory, that which doesn't fit. And I remember finding a German magazine newspaper, actually, from 1919 that talked about a holocaust of 6 million Jews using that language. How could this be? And I researched it. I thought it wasn't even real. And so I went and actually got the original newspaper, and there it was. It's just one of those oddities of life that just happens. Just weird stuff happens. Right.

That's the source of conspiracy theories. Right, Exactly. So weird stuff happens, but, you know, there's a inkling, you know, that that couldn't have been written at another time in history. It was much less likely that little coincidence to have happened in another. So it has some kind of resonance with something.

Yeah.

That captures something deep to the culture.

Yeah. And so I'm interested in probing. I mean, history is about seeing the universal through the particular in a way.

So you look for the weird particular and then pull at that string to see if there's something there.

Is it that weird? You know, I did a project I never published on what I call pseudo swastikas, which is a lot of companies in Nazi Germany made logos that look pretty much like a swastika. If you start looking at them, they're disturbingly like a swastika. And I call those pseudo swastikas. It's one of the many things I've filed away. It'd be a great project. A writer. How did this kind of visual iconography. You weren't supposed to do that. You weren't supposed to sell your bathroom cream with a swastika on it. So they would do these little things that look pretty much like a swastika. Or I would look at humor. What are they laughing at? What are they smiling at?

I didn't even know Germans had humor. Yeah, that's a good discovery.

Oddly enough, even Hitler had a sense of humor. There's one speech he gives which is actually pretty funny, where he's ridiculing all the 29 tiny political parties. Oh, there's a this party and a that party. And it's actually kind of funny. So we do have this, again, this scarecrow image, even, of Hitler and his personality and this and that. But I started noticing that there was this stuff that looks kind of modern. Hitler being a vegetarian and trying to limit alcohol and this and that. And then I got a call, but I'd sort of filed it away. And then I got a call from the Holocaust Museum. Would I like to be the first senior scholar in residence at the Holocaust Museum? I said, well, I wasn't really working on Nazi stuff that much anymore, but I did have this Idea maybe looking at how it could be that the Nazis had the world's most aggressive anti cancer campaign, which is kind of like an amazing fact. And I said it's not exactly about the Holocaust in a way, it's about the opposite. It's about what was Nazism, that it was so seductive that it could become so powerful that something like the Holocaust could be possible. And they said, no, that sounds great, do whatever you want. And so I went down to Washington D.C. and they helped them build a little bit some of the racial hygiene exhibits, some of the push and to show the sort of the medical aspect of the Holocaust. And so I ended up writing this book on the Nazi war on cancer, which talks about how right before Hitler is about to invade Poland, he's talking late into the night about how to cure cancer.

So for Nazis, racial hygiene encompasses way more than we might think. So it's like purifying in all ways and one purifying.

And it's also much more normal and more familiar.

It's like regular, in regular discussion.

It's like the famous line that if Nazism ever comes to Britain, it'll be wearing a bowler hat. And you know, we create an image of Nazism which is this fantasy image.

Yeah.

And you know, they're human beings making.

These decisions and when it's tied to things like removing cancer. So you're saying that kind of the effort of purification walks alongside with this effort of fighting cancer. And then the final, the difficult truth here is that there's a lot of innovation, you know, leading scientific innovation on fighting cancer.

It's not a bunch of blind robots following orders. It's a period of massive innovation. I mean, they declared the soybeans to be the official bean of the Third Reich because they realized how useful soy could be in protein for the people. They built a whole car out of soybeans. They pushed for a whole grain bread, calling white bread a French revolutionary capitalist product. And they're right about whole grain bread. It's better than, you know, so allegedly.

So far, so far, that's what we think we'll discover eventually that bread is the thing that's killing us. Well, by the way, I'm eating mostly meat, so mostly carnivore. And that's been a discovery for me. I don't care what, like, I'm not making a general statement about the population, but me personally, how I feel. I like, I've discovered fasting, so I often, like on days like this when it's pretty stressful, I'll eat Once a day and only meat or mostly meat. And that's amazing to me from a scientific discovery perspective that that makes me feel way better. You know, there's not scientific support why it might make you feel, but I don't care. The point is I've done the experiments on the N of one and it just makes me feel better.

Well, I think fasting is way undervalued. I mean, where do we get the idea you need three meals a day? I have a friend at Harvard and he'll go seven or eight days periodically without food. He drinks water, but he considers it a kind of purification. And we're in a world where it's too easy to get food. We're in a world, I mean, most animals are living in a sense that they on the brink of starvation, but we have technologies and social conditions that allow it's way too easy to find a piece of cake or a donut. And that's not something we evolved with.

We've been talking about purification in negative context, but there's appealing ways of, of minimalism, of removing things from your life of seeking. Especially for me, being like OCD and a scientist, I do like this simplification of things, of this taxonomy of things. I just recently storage got hacked by ransomware for these storage devices called QNAP, NAS and 50 terabytes of data locked up and I can't. So it's lost. But you know, it was at first it was a gut punch and it really hurts and a bunch of stuff is gone. But it's also freeing.

Yeah. Well, there's a. My favorite New Yorker cartoon is where the guy's about to die. Let's say he's 90 years old, he's got tubes in his nose, very last words are I wish I'd bought more crap.

Yep. And that's now in this amazing world. Applies to digital world too. Like you don't need to store everything. You just live in the moment and live for the people that.

Well, that's one of my fears of bitcoin is losing your password. I know a friend, his son mined I don't know how many dozens of bitcoins and lost his password. And so what can he do? There's a whole, I think Silicon Valley episode about something like that where the three comma club asshole billionaire is trying to find his old laptop with the password on it.

Yeah, that's the kind of dread people feel in the modern age, losing your bitcoin password. Or for me it'd be like lastpass password. It's hilarious. We're funny, funny creatures. What else can we say outside of cancer, about medicine, about engineering, lessons about medicine, lessons about engineering and lessons about sort of applied science in Nazi Germany, sort of. Before we leave the subject, is there some truths that resonate with you still that's applicable for today?

Well, you know, historians celebrate contingency or at least recognize contingency. And we always say things didn't have to turn out the way they did. There were, you can't always foresee what's going to happen. And there were definitely missteps.

And.

The potency of that ideology was such that it trapped a lot of people. And I guess by the time it becomes essentially a wartime operation that becomes very, very dangerous when it's blent, whatever the ideology is, once it's blended with warfare that's catastrophic. One of the things that's ignored. I'm very interested in things that are ignored. One of the things that we ignore now on something even like the climate catastrophe is the role of the military. I mean, there's a huge amount of carbon emissions from military operations. Again, just part of the loop. We're not, we're not closing.

Well, military is really interesting because, you know, I'm a AI person, robots, and most of my work when I was a PhD student was DARPA and DOD funded. And I think that's probably true for a lot of science that's funded, especially engineering, is funded by the military. And you know, again, I don't, I really want to be careful drawing parallels between Nazi Germany and any, anything else. But, you know, there, there is a sense in which I remember when I was a. It hit me when one, one of the people close to me when I was a PhD, one of the faculty, she refused to take funding from, from dod, from darpa. That was interesting to me. I thought, but what's the. I mean, it's not like you're not, you're not taking a stand against the war. You just don't want to take money from tangentially associated military kind of efforts. And that little stand, I mean, that had an impact on me. You know, at least it woke me up to them, like, this is something we should be very, very careful with. For me, artificial intelligence is, you know, much of the DARPA research on autonomous vehicles and all kinds of robotics, drones. I mean, that's pure research. Some of the biggest discoveries, like, I didn't think of it as military, I thought of it as engineering and science. But then when the drums of war start beating like, say in Some future time. All of that machine is already there to turn it into. Into Now Lex is walking around and working on autonomous drones that are going to swarm China or swarms, whoever, some terrorist part of the world. And then all of a sudden all my widgets are being used for that. That's why I've been waking up more and more to. There's been something released called like the AI report. Eric Schmidt was one of the co authors of it, which is essentially saying that because China is developing Auton weapon systems, US should not ban autonomous weapon systems and should also be doing it. So basically put AI into our weapons of war. And that the. That escalation, that race is terrifying. Just like all the things you mentioned. But that particular one for me is close because now too closely are the ideas of AI and war are being linked very much.

Yeah. I mean one of the things I think that is rarely taught in universities is what would you not do for money? I mean in a basic class on machine learning or even statistics or history, what would you not do for money? What should you not do for money? I have a lot of my own colleagues who work for big Tobacco, carrying water for them in court. A huge, essentially a mercenary army of historians. A vast undiagnosed, essentially a hidden invisible army. They don't put it on their CVs. And it's going on the same thing with a lot of the technical fields. What wouldn't you do for money? At Stanford there used to be secret PhDs, secret research projects that was kicked off campus in 1971 with the whole 60s radicalism. But nonetheless individual professors still work for all kinds of military operations. We're setting up a new school of sustainability at Stanford. And it's going to be pretty much in bed with Big Oil as well. Big Oil is going to be funding a lot of that. What kind of influence? If they have a seat at the table, if they're giving money, if they're gifts, if their names are on certain projects, what influence is that going to have?

This is what really bothered me. People don't often have. They don't have integrity in the way that I hope they would. This is one of the things I learned in academia. I think a lot of people for money, you know, if I give you a million dollars to murder somebody, I think most people would not.

Right.

A billion dollars, that number starts decreasing. But it's still pretty like I think we would be happy with direct murder not being done for money. But like subtle stuff, just pressures. And it could be with like Let me buy you a drink and just, you know, laugh about stuff, become friends. That's a subtle pressure I'm very upset with. How many people would just unknowingly tell themselves a story, ah, what's the harm? And I see that with, for example, me personally at mit. A lot of people I admire, a lot of people I still admire, I'm friends of mine. I mean, for example, in doing autonomous vehicle research, there's car companies that fund that research. And the car companies say, no, of course we're not going to influence anything. No, that's like you do, it's wide open, do whatever you want. But the fact is, you know, they give millions of dollars. And I'm disappointed that actually a lot of scientists in that context are still afraid. Even though legally it says they cannot, the car company cannot at all influence your research, they still start leaning slowly towards the ideas that that company espouses. And that's a harmless perhaps topic versus big tobacco, but I would argue it has harm on innovation.

Yeah, well, it skews innovation. What happened at Stanford was Philip Morris and the other big tobacco companies, they had a massive denial campaign to deny that exposure to someone else's smoke could kill you, when in fact it can. It kills tens of thousands of Americans every year. Still, they set up an entire conspiracy body called the center for Indoor Air Research and funded hundreds of scientists to basically say, you know, it's all genetic. If you get cancer. Well, you had it coming because of your genes, your ancestry, your hormones, whatever. Well, that was disbar, that was broken apart through what was called the Master Settlement Agreement. But it was rejuvenated and reinvigorated by something called the Philip Morris External Research Program, which continued with the same fax lines and executives funding universities like Stanford. Millions and millions of dollars. And when I came to Stanford, there were millions and millions of dollars being given to medical professors by Philip Morris as part of the Philip Morris External Research Program. Well, what were they researching? They're researching genetics, they're researching diet, anything but cigarettes causing cancer. And giving the friendly research, as Philip Morris often called it, a bigger voice. They got money, they got jobs. It amplified that as a research tradition. Remember, there's nothing natural in a university about how many professors there are of human origins versus AI. This is all a political decision at a very non democratic institution. Universities are less democratic than the Vatican. At least the Pope is elected who elects a president of a university, or a dean for that matter. And so what happened was I helped launch a campaign to get Philip Morris off campus. And people started coming out of the woodwork like, well, does this mean I shouldn't be working for the CIA? Does this mean I shouldn't be working for big oil? It's like what you work for big oil. And our faculty voted against pushing Philip Morris off campus, but Philip Morris got bad press from it, and so they voluntarily withdrew the entire program. So it was kind of a lesson in that you can lose a battle but win a war if you're doing the right thing. And so by standing up, even though our own faculty wouldn't back us in kicking Philip Morris out of the medical school, Philip Morris did a cost benefit analysis, found, well, probably really not worth the kudos we get for embracing Stanford so it can have an influence. And in this case the influence was simply by rewarding, giving voice to the people who were blaming cholesterol rather than cigarettes. And of course we know that historically the tobacco industry created a lot of these theories, these alternative theories of what causes heart disease, that stress causes heart disease, that salt or that anything but cigarettes. They funded that research to basically skew the whole research in their direction.

You are edited a book titled Agnotology. This is an interesting term. So you mentioned it earlier, the Making and Unmaking of Ignorance, where you explore the topic of ignorance or the authors explore the topic of ignorance in different applications in different contexts. Oh, let me ask the ridiculous big philosophical question. What is the nature of human ignorance?

Well, the first thing to say is that it's infinite.

Einstein quote or stupidity or something. I forget what it is. Yeah, well attributed.

Well, the point is that there's probably trillions of planets in the universe and you know, a tiny piece of one. But not only that, who are the we? I mean, we're all born as, you know, we started as single celled organisms, right? Some sperm and some egg get together. That's certainly ignorant. And then we're ignorant. And each one of us, there's an ontogeny of knowledge, you say, but an ontogeny of ignorance as well. We grow up, we have to learn, but almost everything that has been known has been forgotten. If you think about the names of ordinary people and names of the Neanderthal, did they even have names? Most of the history of the world has been forgotten. We have a few shreds, a few traces that we try. History is a kind of resurrection projects, a kind of archaeological project and a genealogical project where we look back and we find traces. And it's very biased. I'm interested in empires that we don't even know anything about. And there are whole empires that are gone if things don't leave a written trace. We know something about Mayan cosmology because we've got some of their stele and a few of their codices. Four codices, but we know that dozens were burned by Diego de Landa, the inquisitorial Spanish friar, who thought these were just heresies and so burned. So that knowledge is all lost.

Do you think there's a lot of deep wisdom about reality that is lost forever?

Of course. Of course.

That's so sad.

Well, it is sad, but the human condition is sad. But then, if we can study ignorance, that's also a positive thing. Agnotology, the study of ignorance, the study of the cultural production of ignorance.

Cultural production. Sorry to interrupt. Cultural production of ignorance.

Yes, yes.

So ignorance is not just manifestation of what it means to be human. It's also forced back onto you through the culture.

That's the missing piece that people don't pay enough attention to. It's not a natural vacuum we explore like some empty cave. It's there are factories of ignorance. The tobacco industry, when they built their propaganda engines to deny that cigarettes cause cancer, they measured exactly how much ignorance could be created by watching one of their videos. They would show that watching one of their propaganda videos in the 1970s produced a 17% increase in the people not willing to say that cigarettes cause cancer. So this is. I call it agnometrics. They actually measured the success of their propaganda. And I'm sure this has been done in marketing and in other fields as well.

That framing of it somehow is terrifying because it seems like a very effective way to be scientific about how to sort of create doubt in the mind.

Exactly. It's diabolical. And luckily, we have some of the tobacco industry's own internal documents. The one that's ones that were not destroyed. We actually know we have some traces as to which ones were destroyed, and we know that the most sensitive were destroyed. And we know that some of the ones that were sequestered by whistleblowers or by disgruntled spouses or whatever, that those contain the real gems and the truth. And one of the ones that was leaked already in 1981 was the doubt is our product memo that we don't just make cigarettes, we make two products. We make doubt and we make cigarettes. We make cigarettes, but we can only keep selling cigarettes so long as we can keep selling ignorance. And that then becomes a template of sorts for climate denial and for all kinds of other denial engines that are Produced by the 1500 Trade Associations in Washington, D.C. so this is something new in the research enterprise of the world. After World War II, you have this enormous trust in science, trust in research. So what could be more effective than Big Tobacco saying, look, we're supporting research. We want to get at the truth. We're funding hundreds of millions of dollars of research, which is exactly what they did. What they didn't say was it was all an effort to distract from the truth that cigarettes cause cancer and a million other diseases, too. Blindness, amputation, all kinds of other diseases. All of that was hidden, covered up through a distraction process. Richard Nixon declares war on cancer in 1971. It's called the war on cancer. Cigarettes were excluded even though cigarettes cause a third of all cancers, all cancer deaths. Cigarettes were excluded because the tobacco industry successfully argued that cigarettes cause cancer is not a scientific fact, but a political opinion. Much like the argument that guns don't cause death. You know, pulling the trigger causes death, or shooters or whatever. In other words, it's all about breaking down the chain of causation into pieces that serve your interests. So it's not that cigarettes cause cancer. It's maybe the smoking them at most, the way they're even denying that. It's the fact you have lungs that cause cancer. It's blaming the victim. And they had a thousand ways to blame the victim.

I mean, there's some legitimacy to this line of argument, which is why it sticks, which is figuring out what is the causation of things is hard to figure out.

A lot of the politics of science have to do with which parts of the causal chain do you view as real or not real when we say that carbon causes climate change? Well, what causes carbon? If it's Exxon causing carbon, is it the person driving the car causing. Or is it the Republican party causing that? Or is it the tea Party causing that? Or is it Big Tobacco and big oil controlling the Republican Party? Or is it what is it the.

Jews controlling the weather, which is where the conspiracy theories come in, or the lizards and whatever sticks you try it out. And if you're a tobacco company, you're going to actually literally be scientific about it and try different options.

The genius of the tobacco conspiracy, the tobacco denial campaign, which is born on December 14, 1953, we know on an hour by hour basis how it worked is to create an alliance between solid research, or as they called it, impassionate, dispassionate research, and to tar all of their opponents as fanatical, emotional, hysterical, political.

You Mentioned Marxism at Harvard a couple decades ago or something like that. So 30 years ago you wrote the value free science book Purity and Power and Modern Knowledge. Which is interesting that you kind of what you were describing then seems to be a concern for people now still. So you're I think referencing more Nazi Germany and how social scientists would attack or defend Marxism, feminism and other social movements using science. There's a big depending on who you talk to. I just spent a day with Jordan Peterson. There's some arguments that science is not being leveraged in some part of the university, which bothers me because most of the university, at least MIT is doing engineering and not ideology doesn't seep in yet. But the concern they have is ideology seeps in eventually if you let it in at all. Anyway, I ask all that. Do you sustain, do you have some modern concerns about the seeping in of ideology into academic research in these social movements for against Marxism? For or against, you know. Well, nobody's for racism but you know, on the topic like anti racism, all those kinds of critical race theory things and then also on the feminism and gender studies and all those kinds of things.

Yeah, I mean these have always been in the university when people have been most adamant in saying that science is a neutral value free enterprise. It's times like the 1950s when there weren't blacks and there weren't even women in universities. So what I discovered was that value neutrality or this ideology of that we are value free, it really arose as a defensive shield to prevent greater inclusion, to prevent questioning of the priorities of science, the practice of science, the nature of science. Now we're in a period now I think of a kind of inclusive revolution where people are realizing, well, we can't have, you know, universities that look too much a certain way. There's probably going to be in that omelet making, you know, there's going to be a few eggs that get broken. And I think people may exaggerate the extent to which that's going at is definitely real.

So like cancel culture, all those kinds of things.

I mean it's definitely real, but it's also, in a way, it's also a distraction from looking at big power in a university. If Big Oil is going to control or at least influence the direction of the sustainability school at Stanford, isn't that a bigger issue than whether we can't say certain words on campus? In other words, there's some very interesting and complex, complex aspects to this and the idea that certain words should not be said or that certain people should not be invited. An invitation to a university is always political. I mean, who do you invite? Who do you not invite? Much as an admissions process is if a student is admitted to Stanford, what that really means is 96% of the applicants did not get in. They were rejected. They were canceled From a Stanford, 4% are admitted. They call it an admissions committee. They should call it a rejection committee.

Yes.

When we hire someone in my department at Stanford, we get 300 applications and maybe we accept one. It's not a hiring committee, it's a non hiring committee.

That sounds like toxic cancel culture. All these rejections.

Everybody should be accepted in that sense. It's the essence of meritocracy, is that selection is involved in any hiring decision. Because in a way, when you were hired into a university, you were hired to control the means of production, at least part of it. And this part of the politics of it is invisible to the undergraduates because they are consumers. And you're free as a consumer to eat whatever you want, but you're not free to own the means of production, to say what's on the menu.

And that's where the power is. You have to ask the question, where's the power in the university? I think that at MIT the entire administration should get fired regularly and more power put in the hands of faculty and students. There is an overgrowth that happens that it feels like administrators are more easily influenced by Big Tobacco than faculty. Maybe it's me being sort of romantic about the idea of faculty, but if you're in the battle doing the research, I feel like, well, I don't know, I don't know, I don't know. But it feels like the administration helps you delude yourself longer so it prevents you from waking up. It's like, no, no, it's okay to take this money. Oh, Jeffrey Epstein, it's okay. And oh, okay, so he went to prison. Let's just keep it a little bit secret. It's fine, just keep taking the money. And I feel like that comes from the administration more than the faculty.

Well, there's certainly a cult of celebrity, a cult of money. Donors have the. Remember in the whole scandal about the side door entrance in universities, there's always been the front door and the back door, but the back door is the rich donors, the kids of the rich donors, the legacy kids that you still get. So there are a lot of ways universities get corrupted. They get corrupted through money, they get corrupted through influence. And that should be recognized.

We're jumping around a little bit, but I read you also do work on human origins. So we mentioned this earlier. Let me ask another big philosophical question. What's human? What makes us human? What is human? And where did that humanness come from?

That's exactly the question we need to problematize because it's what I call the Gandhi question. It's like, you know, Gandhi's asked, what do you think of Western civilization? And he says, it would be a good idea, you know. And so when did humans evolve? You know, well, not yet. So we don't talk about, you know, when did you know. We talk about the rise of modern humanity and what's happened in the last 50 or 60 years or so, which I think is a good thing intellectually, is that we've smeared out humanness to mean many different things. It's not just tool use, it's not just upright posture. Upright posture goes back at least five million years. Tool use goes back at least two and a half million years, stone tool use. But since wasps and chimpanzees use tools, then it's got to be even older. So that's actually one of the things I'm interested is how have different notions of what is human influence our theories of human origins. And in particular, there's sort of the problem of what I call sodomy in the uncanny valley, which is how long ago would you be willing to date someone that existed, say 5 million years ago, 10 million years ago, 3 million years ago? In other words, when is it like.

Date or one night stand? I mean, strong either one.

All right, let's say be the, the mother of your children.

That's a lot of commitment.

But yeah, but it's an interesting question because after World War II, as a result of Nazism, no one wanted to be the one to say that this particular fossil we've just found was anything less than fully human. So there's a projection of humanness arbitrarily back into the past, so that even these little monkey like creatures, ramapithecines, ramapithecus, were being declared to have folkways and mores and language, which is ridiculous. No one wanted to say that Neanderthals were anything less than fully human. So it's a very interesting question, at what point are they us? I mean, human origins is very much an identity quest. It's when did we become us? Which sort of begs the question, what are we? Who are we?

How much is that is the hardware evolution question versus the software? Like what the actual development of society. Like, can't you argue that we became human? With, with agriculture. I mean, can't you argue that we became human with the Industrial revolution?

Well, certainly by then they are us. But agriculture is only 12,000 years ago. That's a blink in the eye, right? That's yesterday. It's interesting. Prior to the 19th century, most scholars thought that the pyramids were at the beginning of time. Essentially they were closer to the beginning of time than they are to us now. It's a blink in the eye. We use the metaphor of a meter. The earth is 5 billion, so that's a meter. The natural history of upright humans is 5 million. So that would be like 1 millimeter. It'd be the thickness of the white of your fingernail. And then the pyramids are 5,000. So that's a thousandth of a millimeter a micron, which is the amount taken off when you brush your fingers on your, your jacket.

So.

There'S a natural history of humanity, and then there's the history of our constituents. We're all stardust because all of our complex atoms began in supernovas many billions of years ago. But upright posture, 5 million, agriculture only a few thousand years ago. We cultivate dogs a couple hundred thousand years ago. So those are Paleolithic instruments. Cats are Neolithic instruments because they're used to kill vermin. Dogs are used to hunt with us. But there is what you say, this co evolution, our social aspect and our physical aspect. Even the fact that we have whites of the eyes. We're the only animal with whites of the eyes. And the whites of the eyes tell intent, they tell direction, they tell interest. They know if you look at something, I can tell what you're looking at because there's a lateral resolution. I can tell what you're looking at. That's recent. And the people who do reconstruction for museums, they want to create what I call an ethnographic identity with the viewer. And so they fantasize about all these other early hominids, non human, pre human hominids, if that's a word, as having eyes like us. But they probably didn't. And they were probably not self. Aware. At least the early ones can't have been self aware the way we are. Insofar as we are, they may not have spoke. So I'm interested in basically when did we become what we think is human? It's clear that when we start burying the dead and making jewelry, and when we in a sense invent fantasy, when we invent deception, that's human, that's fully human. We become human by thinking there's a World that really is not.

I mean that feels like we're start to operate in the space of ideas more and more. So to have deception, to have imagination, you start to be able to have ideas and share them and it feels like the sharing is the thing that really develops the idea. So it's not.

You come up with ideas and you, we become able to sort of understand what each other is thinking. Some animals can do this to a certain extent. Dogs have a certain empathy, but it's limited. It's highly limited.

But you could probably argue that the dogs got that from the humans.

Yeah, I mean humans and dogs have co evolved, have definitely co evolved because it's over a hundred thousand years we've been working together. They are. But all our hands have evolved with tools. And so I'm trying to figure out now the original purposes, purpose of Acheulean hand axes, the old, the first beautiful tool made by humans which were made unchanged.

What kind of axes?

They're called Acheulean hand axes. They're these beautiful teardrop shaped objects that go back 1.5 million years.

And what's your thought about his possible purposes?

Well, the most important thing to murder.

Is that a jealous, jealous husband comes home.

What's astonishing is that no one knows what they were used for. So they may have been maps, they may have been weapons, they may have been chopping devices, they may have been sexual displays.

Oh, like ornaments to, to display something versus actual practice.

Like the peacock's tail, something to attract a mate. No one really knows. But what's interesting is how in becoming ignorant of those, that's a form of knowledge. In other words, a lot of this is one reason I'm interested in ignorance is that really to understand something and especially to teach something, you have to know what people don't know. And that's hard. Often it's very hard to remember what it's like to not know something or once you know it, very hard, very hard to do. But you sort of have to do that to recreate that moment. You can, you can teach.

Well, one nice thing I like about the Internet is you can look at old tweets of yours and to be like, okay. For some reason it brings to mind like okay, that's where my mind was. Another interesting exercise is like Google search history. So I think for everybody you can look up your own history of what you searched for. And it's so cool to go back to like 2008 or something like that. Like, okay, I remember where your mind was and immediately actually it's a nice way to restore at least an inkling of the ignorance you had. Like, have a peek into the ignorance you had about the world. And also to discover the things you've forgotten. The new ignorance you have now. He's like, oh, right, right. I was really concerned about this and that. I do think that, as you're saying, it's both sad and illuminating to think about that most of what we've known, even like the deep wisdom, is forgotten as a human civilization.

But we create it new all the time as well.

Right? Hopefully forgetting is a feature and not just a bug.

It's like those mice that can't forget, they go insane. Right. If you imagine all of your memories is present, that's a recipe for insanity. You have to forget to learn. Learning is unlearning.

Which is exactly why I drink.

No.

And then write some blues songs about forgetting a broken heart. Okay, you mentioned amber and stone collection. I just have to ask, does that connect to human origins or just a personal love? What is it about stone collecting that attracts you?

Well, scholars tend to be text oriented. I tend to think books are overrated. We evolved without books. I walk for a couple of hours in the forest every day. I gather mushrooms and all kinds of things. Just located pieces of the 1953 Resolution airplane crash outside of Half Moon Bay just a couple days ago. I like finding things.

Have you ever found pieces of a crashed ufo? Not yet. Okay. All right. Let me know please if you do.

But of course we have extraterrestrial other stuff. I mean, we have. I have. I collect meteorites, so I'm into that. And so I'm interested in stone. Stone quality. I grew up in southern Texas and grew up surrounded by people who would hunt for stone and gather stone and cut stone. I cut stone as well. I'm a lapidary. And so I have this interest in the physical qualities of objects. Sometimes it's called material culture, but it's just stuff. And I'm interested to know how different cultures have manipulated stuff, worked stuff, stone, wood and things like that. And also the fantasies people project into it. So I'm doing a book on all the different ways different cultures have found different images in stone, like Rorschach tests. And so in India, they love agates with Hindu temples in them and altars. And in America, they like three crosses on the mount. And if you can find a stone with the word Allah in it, that's beloved in Yemen or Saudi Arabia. So there's a long history of people projecting fantasy into stone and I'm using that as a kind of a metaphor. I'm also looking at the rise of hobbies and amateur stonework and how a lot of our gemologic techniques were actually invented by amateurs, which means just lovers as opposed to professionals. The amateur is the lover. And hobbies, I don't know if you know, but the word hobby comes from a hobbled horse. And so you would hobble a horse to keep it from running. That's hobbling it with a, with a stick or a string. And then kids would ride a hobbled horse for play a horse on a stick. And riding a hobbled horse becomes riding a hobby horse. And then that becomes a hobby. And so hobbies become this so called job you can't lose in the Great depression in the 1930s, and then they explode. And so when I was a kid, people would collect coins or stamps or fossils or this or that. So I'm interested in that collecting passion.

So it's interesting, the development of hobbies because it feels like the future of human civilization will be very hobby driven. Like some of the, like I, I often now, because of this particular little thing I'm doing with the podcast, I get to interact with photographers and videographers. And I'm disappointed to find how many professionals are not very good and how many hobbyists are very good.

Yeah, it's.

So it's.

Well, if they're amateurs, they're the lovers. I mean, that's what that means from amour. You're an amateur if you're a lover of the thing. And it. You're not in for the money. Yeah, you're in it because you're obsessed.

But sort of as the gdp, as the, as our freedom grows to sort of financially to be able to have a hobby, it feels like there'll be more lovers, more amateurs in the world. And not just for the artistic pursuits, but like science, technology, development, building, you know, building all kinds of technologies. Almost like as a hobby. Yeah, you have much more freedom to figure out what is the thing you love doing. And actually over time that just you won't even notice, but it'll start making money. And yeah, that's really fascinating. And yeah, it does kind of. I mean, when did that originate? Just the collection.

It goes through different stages. People have always gathered the odd thing to make something else. But you also get this tradition of what's called curiosity cabinets, especially in the Renaissance, which replace the kind of treasure chambers of the ancient sultans or kings or whatever. And you get these curiosity cabinets, they were often linked with Magical practices, alchemical practices, people would gather bezoars or they would gather, they would have an alligator hanging from the ceiling or they would have a rare, you know, shrunken head or whatever. And that's part of the rise of natural history, the idea that you taxonomize the world, you classify the world, you look for the rare object, the rarity. And rarity still is a kind of virtue. Like the recent news about trying to figure out ball lightning. When I was growing up, ball lightning was the big question. Does it exist? Does it not exist? And now there's new evidence of how it actually might.

Wait, what? Really? There's new evidence? Yes. Yeah, I grew up with that. My dad when I was young told me, I asked him like, how do I win a Nobel Prize? He said, invent a time machine or figure out how ball lightning works. And so I got really excited. I was like, damn it, I'm going to figure out how this ball lightning works.

It's very interesting from a history of science point of view because it's so rare that in a way it doesn't exist. You can't replicate it, you can't make it. Does it really exist? It's a little bit like Libyan glass. Another thing I collect is Libyan glass, which is a tektite, which falls as a result of a meteorite. A meteorite hits the earth, blasts earth up into space, it falls back down as a glass that's called a tektite. And there's a rare form of it called Libyan glass, which fell probably around 20 million years ago and now works out of the Sahara every now and then. It was the most valuable stone of antiquity. The centerpiece of Tutankhamun's breastplate is made of this beautiful yellow gemstone, Libyan glass. So rarity is something that, that the hobbyists have always liked to cherish. The rarity, the odd. And science has a kind of often aversion as a kind of a love hate relationship with rarity and novelty. Science is often trying to pursue novelty to make discoveries. But if you can't replicate it, it's kind of like what? Does it really exist?

Yeah, which is why I mean UFOs and aliens and all those kinds, there's a general aversion to that because it's like it's a one time event. Right. It's, it's sad because there's a, just like you said, singular events or rare events are somehow really inspiring to us. And so you kind of have to balance that. Yeah, there's a scientific process, but you Also have to like. Oh, it's the thing you, you find with the weird, the, the peculiar. It's like, huh.

Yeah.

What is it?

Even, even the universe itself. It could be that the universe begins and then will end, say in a cold death and that's it. I mean, it could be a one off thing or it could be one of an infinitely many cycles. And maybe all of the laws of nature are recreated anew with each cycle. Yeah. Or maybe what we're assuming about the Big Bang, there's some element of falsity, maybe the speed of light is not constant, but changes over time. That would throw into question all kinds of theories about dark matter and dark energy.

Yeah.

And even the age of the universe.

And I, to me, there's very likely trillions of conversations going on like this on other planets.

Yeah.

In different.

Yeah. No doubt.

There were different kinds of drugs, different communication styles, different time scales at which life form is, or what life looks like or how life behaves of what life is. And all those things, it kind of.

Yeah.

Every time you think about this, it's more and more humbling. It's just this whole fog of ignorance.

Yeah. I mean, I mean, what drives me crazy is wondering about the beautiful gemstones on other planets. I call them exo agates. You know, they must be unbelievable features and forms which are unimaginable.

Yeah.

To us. Because one thing we do know is that nature is very creative. I mean, we are the product of nature and we seem to be fairly creative. And so imagine what else nature's created. But even that's unknown. You know, is how common is life in the universe? Is it, is it common or is it rare? We only have a sample size of one. You know, it could be quite common or it could be even unique.

Yeah. I tend to believe it's everywhere, except for the fact that we don't even know how to define what life is like what is everywhere exactly. We're talking about. It's, it's very possible that there's not anywhere in the universe an organism with two legs and two arms, with two eyes and mostly hairless walking around at this time scale. But like there could be very different kind of other things. It was interesting. There's some people, this is not a common belief, but a friend now named Lee Cronin, he's a, he's a chemist and biologist and he believes that if we ran evolution over and over and over and over on Earth, you get very different. Not just. You wouldn't just get different organisms, you get Very different biology.

Yeah, it's quite possible, yeah.

And that's a weird thing. I mean, most people kind of assume, well, it kind of, you know, it fits to the environment and you're going to get similar things, maybe not humans and so on, but to get very different biology, like starting from the bacteria to the, you know, just how?

Well, the idea that it would be DNA based, DNA based on some other planet, that seems to me like saying they're speaking Swahili on some other planet. I mean, the odds of that particular architecture, I think, are infinitesimally small.

What's the coolest stone you've ever seen?

Oh, my God, there's so many.

And what defines. Is it rarity? Is it just raw beauty? What captivates you?

I like excitement. A storied stone. I have a very beautiful Fairburn agate, which has multiple layers and there's something I call agate paralysis, because to polish it you have to go through the layers, which means you're destroying the layers. And maybe what should be done is it should be like a movie where you, you film the entire process of cutting and polishing so that it's not dead. In other words, what was the diamond when it started rough? The rough diamond is gone. But if you could sort of do a filmic version of a cutting process so that the stone would exist from a pre polished to a polished state. All as a kind of NFT or something.

That should be an nft. That's right.

So the other thing I fantasize about is how pattern recognition technology will probably in the future allow us to discover all kinds of amazing stones, including, for example, fossil skulls of humans. Now, it's kind of a chance process that you discover a skull in East Africa, but why not have a drone moving, constantly scanning for pattern recognition of human skull, human teeth, very slowly and then on the surface. You mean just above the surface? Just 10ft above the surface? 20ft above the surface?

No, no, no, sorry. You think you'll be able to find skulls on the surface?

Yes, yes. In the middle of a place that no one has looked. And these areas are vast. Right. So it could be found on the surface, then move to the next layer, then find it under the surface as well. There's Lidar, there's all kinds of ways. We're finding jungle cities under the Amazon that people didn't know about.

Do you think there's something out there that would just blow your mind?

Oh, for sure, for sure. Yeah, no doubt.

Oh, man. And how much of it is a little Bit underground.

Right.

Or how much of it is in the ocean.

Yeah, I mean, here, right here we are in the Bay Area. We know that much of the Native American civilization here was under the bay because 6,000 years ago the bay was dry. It was a river, not a bay. And so all of those whatever material culture, archaeological traces existed there are now at least preserved under the water. So I think we're just beginning to touch the, could be treasure too.

I mean like literally, like you said, we lose the wisdom or we lose the knowledge.

But.

I mean, if there's the pyramids, right? It's the great wonders of the world, there might be other wanders that are completely lost.

Yeah, just, I mean, one of the stones you asked about stones. I like, I like stones. For example, every now and then dinosaurs would eat rocks as gizzard stones. And then you find them in their guts, in their bones. Well, every now and then they would eat a piece of petrified wood. So the idea that something was a tree and then stone and then swallowed by a dinosaur and ground up in the gizzard and polished and then left in a. You know, So I like things that have been through dramatic.

There's a story there.

There's a story.

Yeah. I mean, that, that's okay. The really fascinating thing, why seeing Allah or crosses in the stone is it feels like the stone has wisdom because it's been, there's, there's a. It's been through so many generations of humans. It's like bigger, right? It's seen it all.

Also. It's also the intellectual question of intelligent design. In other words, when people say intelligent design, mostly it's bogus. But there are several interesting examples of actual intelligent design. Meaning when is a stone the product of artifice and when is it a geo factor produced by nature? And that was an important discovery in the 19th century. The zone of percussion. It's called the percussion zone. Or how do you know that a signal from out of space is an intelligent signal? And as opposed to hydrogen doing something or some natural thing, that's the genuine problem of intelligent design. How do you know if it's PI, maybe if it's E, if it's some, you know, pattern, how do you know that that's an intelligent signal? How do you know that an artifact in the ground is, you know, we'll see in the clouds of a face. It's called pareidolia. We have a kind of a built in ability to see faces where they really aren't there. Right. That's why kids like clowns, you know, we've evolved that. So babies evolve it to recognize their parents and so forth. But when is it a projection and when is it really in the stone? And that was a big question. With the rise of fossils, you know, if you find a curly thing, is that life or is it non life? Is it. You know, people have made this mistake before. You know, they'll find a rock on the moon or Mars. They say, oh, this is a face or whatever. Well, you know, no, that's just projection. That's pareidolia.

I guess throughout science, you have this problem of signal. It. Just because something is beautiful doesn't mean it was. I mean, that's. That's not a good signal to determine if it's intelligent design or natural evolution or natural design. Just because you're. You see a stone that just. Yeah, the pattern is. Is incredible. How do you.

What do you know? How do you know it's a fossil? Is one question. Namely the remnants of an organism, and how do you know if it was manipulated by a human? This is a big problem in trying to figure out the oldest art. If you find scratchings on a bone, is that a tally? Is it someone marking her menstrual period? Is it phases of the moon, or is it trampling by an antelope? And that's called the science of taphonomy. To discern when a marking on a bone or a stone is in a sense an artifact or a geo fact or an antelope effect. And it's an intellectually challenging question. And people want to fantasize they'll find a stone. It looks like a carving is 300,000 years old. Generally, I think those are just odd stones. You don't find the explosion of carved stone until around 60,000 years ago, 50, 60,000 years ago. There seems to be something that paleoanthropologists call the creative explosion or the big bang of the mind that produces a kind of ability to see in the distance, to identify a shape in an object, to create a shape in an object that you don't get. The Neanderthals don't seem to have ever done what we would call art. That's a very interesting phenomenon, but it requires that you have some understanding. When is something art and when is it just, oh, that's a rock that.

Looks like a face or some not necessarily understanding, but a conception that's mutually agreed upon that we're able to. Because maybe Neanderthals, maybe fish have a conception of art. They just.

And this also gets Back to your question about professional bias and ideology. Because there's a huge reward for finding the oldest art. If everyone says it's 50,000 years ago and you find one that's 300,000 years ago, that's a huge discovery. So there's a bias. And this has been one of the things that's led to the art, probably the over proliferation of different species of hominids because there's no academic reward for finding yet another example of someone else's species. But there's a huge reward if you can find a Lex Friedmanite, you can name it after yourself or whatever new fossil. There's a huge professional reward to be the first at something. And so those types of professional rewards also influence science and what kind of science gets done.

Yeah, so I'm always suspicious of and as we should all be when you can kind of intuit a financial and otherwise motivation. I mean that's actually often in the modern age where I'm suspicious of conspiracy theories. It's not that the logic doesn't make sense or something like that. I personally actually just enjoy conspiracy theories. I've been listening to flat Earthers discuss stuff recently. It's kind of exciting for some reason. It's like, because, because I consider, like what if it's true? It's exciting to discover together. Like think through first principles. Like what does the world look like? It's exciting. I mean that's, it's the childlike discovery of a new idea. But the reason I'm skeptical of a lot of conspiracy theories is when I see how popular you can get propagating those conspiracy theories, how quickly you can form a large movement and it's like.

Like, well, on such thin evidence, it's like if Loch Ness exists, there's just one. I mean, how does the reproduction work on See, but how do you talk about an animal that has only one in a population? It just doesn't. Some of the things don't make sense.

No, but see, this is the logic side. I don't even go that far. I, I, the fact is if you say there's a Loch Ness monster, I just see how quickly the idea spreads in popularity. It's the people are hungry to discover something new, just like you mentioned with the hominids. And I'm very suspicious of where there's like a strange hunger for ideas because then they're less likely to be objective and rigorous in considering the validity of that idea. I'm not going to the logic because actually flat Earth is pretty logical.

Yeah, very logical. Logic is not the problem. Right.

So it's, but it spreads really quickly. And I, and I once again with conspiracy theories. I think it represents, it's. You have to think about the cause of causes or cause of cause of causes like you talked about, which is like it represents some deeper fragmenting of the, the common humanity. We have the, the, the trust in the, in the, in the big community that is science and the big community that is government, all that kind of stuff.

Well, that's why things like ball lightning are cool, because it's like the scientists denied it, but here it is.

Exactly, exactly. And that's ultimately ends up.

Everyone said I was insane, but, and.

But it's still exciting. You said there's some breakthroughs. I need to look it up. Yeah, it's really cool.

It's pretty exciting. Yeah. There's some new theories of how it.

Actually might because I think, I mean there's obviously several ways to prove that. Like one of them is to recreate in the lab, which is standard. That's probably very, very difficult. Just because we're on the topic of rocks. I don't know if you've heard about this interstellar rock that flew through our. Called the Muamua.

Yes, that the cigar shaped one.

The cigar shape was a fan of rocks. What do you think about that one? So.

Well, I think that generally, I mean, when the people were speculating it might be a spaceship, I thought, come on. Rocks do all kinds of crazy things. They do a lot more than you realize. They can do unbelievable, unbelievably cool things. There are parts of the desert there in Utah where rocks move and create these long tracks. And it's. Now we know it's from liquefaction and wind and various other things, but they're still unbelievably cool. Rocks can do almost anything. And so just the fact that one comes from outside the solar system doesn't mean it has to be a spaceship. But nonetheless, I thought it was awesome. I thought it was really, really cool. And I sort of wish it would happen more often.

I kind of hope it's trash from another alien civilization.

That'd be fantastic.

Because if you're, if humans are at all a lesson that we produce more trash than we do intelligent signal. So the first thing to reach other civilizations I feel like would be our trash, our pollution before the intelligence signal reaches them. You mentioned this interesting term Russianist, the things we do for love for some reason. You went to Germany.

Yes.

So you said you're pretty eloquent with German.

I learned German, yeah.

Did you ever learn Russian? A little bit.

I did learn Russian, yeah. I studied actually Russian as an undergraduate at Indiana University for several years. And then I wanted to do a rush. I wanted to do Russian and Chinese as a graduate student because I thought this is kind of the future. And Harvard said, no, it has to be French and German. And so I essentially gave up on my Russian and Chinese. And the other part of that story is nonetheless, I wanted to do something with Russian. I wanted to study how much the Lamarckian ideology and biology in Russia at the time that led to their distrust of genetics under Stalin had to do with the fact that genetics was being pushed by the Nazis. And we tend to see those literatures in isolation. The Nazis were racists, the Russians were environmentalists, biased by Lamarckian theories of heredity and rejected that part of Darwin. When they're right next to each other at the very same time, there must be a connection. And so I started reading into this and I actually got a Fulbright to go write a book on this and canceled all my classes. I was teaching at the New School for Social Research at the time and I couldn't get a visa into the Soviet Union. I was just barred admission for doing this project. Looking at how Stalinist science had this anti Nazi aspect which we've overlooked.

Which year was this? This was. The Soviet Union was still together.

Yes, it was in the late 1980s, but before Gorbachev was in power. But it wasn't before 89.

But still then there was a careful attention to.

Well, you never know how careful it was or pull through the cracks or. You never know when something fails. You don't always know why it failed. But I was very disappointed and it sort of ended that project. I didn't have access to archives on it. I could have obviously done it later, but you know, so like there was.

That curiosity initially, but. And then you focus on Nazi. On the, on the Nazi side of.

Yeah, I mean, the other thing was I was trying to figure out where to go for. For a Fulbright on a different year. And I wanted to go to China and turns out you could only go to Taiwan. I didn't really want to go to Taiwan. And it was 1 in 50 odds of going to Taiwan, but it was 1 in 3 of going to Germany. And so I ended up going to Germany. I didn't have any particular interest in Germany at that time, but that's what I ended up doing is. So I wrote, you know, I wrote one book in German actually, and I Wrote two books on Nazi Germany. And, you know, otherwise I might have been doing the same thing in Russian or Chinese.

Yeah, those are.

In other words, history chooses us as much as we choose history. Right.

And those are really powerful cultures. Right? Maybe. Can you comment on the German and the Russian and the Chinese? How much language. When you were reading those medical journals, how much are you able to understand? How important is it to understand language deeply in order to understand the culture? Did you struggle? And the opposite of that, did you find the beauty of the moment, richly understand the moment because you had a hold of the language?

Well, in the Russian or Chinese case, no, I never got that far with it. I knew enough. I could read some Russian and I could tell there were anthropologists who were anti Nazi and therefore anti genetics, and they saw genetics as essentially Nazi. And that was enough for me. I know there's something there, but I didn't have enough time. I wasn't allowed to go and actually research it. In the German case, you never fully know a language. We don't fully know English. There's always more to learn. I'm always learning new. I didn't know the word done last year. D U N means some kind of brown color. And I'm always finding new words. You know, it just kind of. The words are near infinite as well. Right. And new combinations. I've coined several words too, in my life, but it did help understanding the humor, understanding the romance, and mainly just plowing through all of these medical journals, one after another after another. There's a kind of a voyeuristic aspect to looking into this lost world. You're reading texts by people who've died.

Long ago and direct. It's not like reading books by famous people. It's like real people.

People. It's real people and they make mistakes and fascinating little stories. I was looking at how the Nazi tobacco industry had their own denial campaign, which was pro Nazi and pro tobacco, even though the Nazi regime was anti tobacco. And they developed a lot of these rhetorical tricks that were later used by the Americans, like, oh, you can't trust that evidence. It's merely statistical. You can't trust the animal experiments because all it proves is that mice should not smoke. But I notice just in passing, these remarkable stories, little hints. There's a report from a Japanese military man in one of these tobacco journals, tobacco industry journals in the Nazi period, and they're talking about this brotherhood of all men through cigarettes and the tragedy that the Chinese and the Japanese, who are fighting each other in a way Wanted nothing more than to smoke together. And the Chinese would sneak up to the Japanese forts to try to find a Japanese cigarette that had been thrown away. And they'd be glowing, and the Japanese knew this, and they would throw their cigarettes out. The Chinese would come, and then the Japanese would kill these Chinese. And then this guy is poetically lamenting the fact that even though all they want is a smoke, they nonetheless end up in the crosshairs and in death. And so it's just weird. And I'm reading this translate from the Japanese into German in a Nazi tobacco industry newspaper. I mean, the layers of weirdness are really fascinating and touching, but.

And those very kind of brotherhood stories actually resonated later because, I mean, that's how I feel about cigarettes. Some of my favorite moments in early life is about people connecting over a cigarette, of course. And that, you know, that works. That. That's those narratives.

Yeah, it's the movies, right? The movies called Meet Cute. They. The tobacco industry, when they put cigarettes into a movie, they put it in right at the moment where boy meets girl.

Let me ask you just in all the research you've done with. With Nazi Germany, just for me, from a conversational perspective. I was. I was listening to a bunch of Holocaust survivors recently just on YouTube, listening to interviews, also listening to Nazi SS soldier, like they're still alive or were recently, some of them, especially the ones that deny many aspects of the Holocaust. It's so interesting to watch because they're still. Still. It's so fascinating. Anyway, I. In your research, are there interesting people to talk to? They're still alive, or are they mostly. That part of history is no longer living, is in the books.

It is mostly no longer living. That's one reason in the 1980s, when I started working on Nazi science, I really did interview quite a few people and elderly people, people who had sort of slipped through the cracks, maybe even should have been prosecuted. So few people got prosecuted, but these were people who had racial theories, who published. Yeah. You know, on these topics. And they were guarded, but these were the lives they lived. And, you know, mainly they wanted people not to be talking too much about this. So it gets sealed off and walled off. And that's why the reading, the medical literature itself was so much more valuable.

Because there's no self censorship. It's just there.

I'm sure there's some censorship, but what they said is what they said, and it's immense. It's immense and largely unread. As I said, there are hundreds and hundreds of Nazi Medical journals and people had not been reading those before I really started looking at them.

Given that you studied these really difficult parts of human history and human nature with big tobacco and just these mechanisms of manipulation, what gives you hope about the future?

Oh, all kinds of things give me hope. The, the forest gives me hope. The Wikipedia, nature. Wikipedia. Wikipedia gives me hope. Space exploration gives me hope. All kinds of things give me hope. I had this insight the other day. I walked through all of these giant redwoods which, which were almost all cut. They're not very far from here, just, you know, half an hour straight west of where we are now. You end up in redwood country. And I had this idea that they're growing back now and every year they add how many cubic miles of wood if you count California as a whole. But not only that, the roots are all old growth. If you think about it, these are resprouting. They're not from seeds, these are resprouting. So they have this tremendous resource underground that even the loggers couldn't kill, right? And so from these stumps you get what are called fairy rings, which are like five trees coming in a ring around it, each one competing to be this successor. So they've seen this story before and they know to re sprout. And that I think is a very hopeful thing is that the roots are old growth. And hopefully in 100, 200, 300 years, it won't peak until around a thousand years from now. You'll get these restoration of all of this magnificent old growth. But so many other things give me hope. We have to have hope. And I think that if the world is infinite, there's infinitely many ways for it to become fixed. I mean, obviously we have some problems need to be fixed, but they're fixable.

That's really beautifully put. That is a really hopeful idea. That nature, that life, even human civilization, is resilient to all the mistakes we make. So the roots are there. So it outlives us, it's patient with our adolescent fuck ups.

I mean, we're a thin layer on the crust. And you know, eventually the earth will be swallowed by the sun and humans will have long gone extinct by then. But yeah, there's all kinds of grounds for hope.

So us being a thin layer of crust, what do you think is the meaning of this layer? What's the meaning of human existence? What's the meaning of life?

Well, I think it depends who you're talking to. If you're talking to a raccoon, it might be one thing. If you're Talking to an old growth tree, it's making sure you're straight up upright and not, you know, on a slippery slope. Yeah, fish, I guess they're trying to avoid the hook. Right. No fish ever, when they take the bait, no fish in the world has ever said I hope I get hooked. And that's one of the problems with tobacco is that there's all this bait and people get hooked. But you know, the fish don't have heads. We have heads. One of the great innovations in the history of humanity going back way pre, I mean is the invention of the head, the mobile head that turns and sees, you know, and the fish didn't have that, you know, they didn't have hands. The octopus have cool stuff.

Yeah, it's not all about the head.

It's not all about the head. Well in fact the octopus basically, they've got brains in their fingers.

Maybe brains is not even that good of an invention in the long arc of history because the fish maybe got it right. Stay in the ocean.

Well of course we evolve from fish.

So yeah, but we moved on. Is there a why to this or is it just the way it's, it's like the current, it's just, it's just like these pockets of interesting complexity pops up like, like Allah showing up on a rock. This is what human civilization is. This weird little thing that showed up on a rock and then it'll disappear.

Well, we are probably the most remarkable creation that nature has ever belched forward. We're probably the only one if you don't count the KT meteorite that just almost destroyed the earth. We're the only ones that really have the capacity to destroy the earth. I'm fascinated by the meteorite that wiped out everything bigger than four feet long. The Mount Everest sized meteorite that hit the earth 66 million years ago and destroyed most species in the water and on land.

There could have been some smart folks around then too.

Well actually one thing I like to think about is that 232.3 million years ago and 232.4 million years ago. That's 100,000 years. That tiniest of a sliver, maybe a millimeter in most parts of the earth. It's enough time for a species of dinosaur to become intelligent, build a civilization and go extinct with no traces. And maybe that happened.

Our ignorance can fully engulf the fact that that happened. Oh the beautiful self importance of us human. It's easy to forget that multiple intelligent civilizations could have lived on earth.

It's possible and gone Extinct or even life may have evolved more than once. Not only that, but proto life may still exist. And we were not even looking for it. You know, some type of clay that became life may still exist. And people. One thing I like to think about is always, what is the before time? That is now I remember lecturing about this right before COVID and it's sort of like, what is the. What is the our world now that we'll say, what was it like to be then? Before.

Yeah, before.

And that's the world we live in. We live in a before time for something we really can't predict.

Probably physical.

You know, appendages, you know.

And being in person, being able to touch each other or wanting to touch each other versus being, being in the digital world. Right. This whole idea of the metaverse and more and more moving into a digital space, what was it like being born before most of your. Your life wasn't on the computer? Yeah, it's pretty damn good for the record, but maybe, I don't know, the alternative. Robert, this is a fascinating conversation. Thank you for taking us through some dark periods of human history, but I think they contain a lot of lessons for today, that science is often inextricably connected to our values, to our ethics, to our politics, and that's something we have to contend with. So your work is really important and thank you for shining a light on it.

Thank you.
