A philosophy class at Princeton centered on Peter Singer's work taught the speaker to follow beliefs to their logical conclusions and sit with the discomfort. When a belief leads somewhere you don't want to go, you have to either abandon it or figure out why it still matters.

I would add one more class that had a huge influence on me. It was, it was an intro to philosophy class at Princeton, and most of it went over my head. That's not me. But there was one person we did a lot of reading on, a guy named Peter Singer, who's a professor at Princeton who is quite controversial in certain circumstances. But what I loved about his approach was that he challenged us to think about what you believe and challenge yourself to follow that belief. To whatever it ultimately leads you to. It's like, if you continue to believe that, what does that end up meaning in terms of your decisions and so forth? And when you get there, if you find you're not so comfortable with that decision that it leads you to, you said, that's great. Now it's time to step back and think about, so do you really believe that or not? Or how can you reconcile the fact that your belief led you to this decision, which you don't like? Because most obviously you have other beliefs as well, and things don't work out. But what I loved about his approach was this challenge to ourselves that believe your own ideas, trust your intuition, but challenge yourself. Think deeply about these things.
