“Let's start with a test: Do you have any opinions that you would be reluctant to express in front of a group of your peers?If the answer is no, you might want to stop and think about that. If everything you believe is something you're supposed to believe, could that possibly be a coincidence? Odds are it isn't. Odds are you just think whatever you're told.”

“You can't distinguish your group by doing things that are rational and believing things that are true. If you want to set yourself apart from other people you have to do things that are arbitrary and believe things that are false.”

“At every period of history, people have believed things that were just ridiculous, and believed them so strongly that you risked ostracism or even violence by saying otherwise. If our own time were any different, that would be remarkable. As far as I can tell it isn't.”

“You need three things to create a successful startup: to start with good people, to make something customers actually want, and to spend as little money as possible.”

“Someone trying to live well would seem eccentrically abstemious in most of the US. That phenomenon is only going to become more pronounced. You can probably take it as a rule of thumb from now on that if people don't think you're weird, you're living badly.”

“If you leave a bunch of eleven-year-olds to their own devices, what you get is Lord of the Flies. Like a lot of American kids, I read this book in school. Presumably it was not a coincidence. Presumably someone wanted to point out to us that we were savages, and that we had made ourselves a cruel and stupid world. This was too subtle for me. While the book seemed entirely believable, I didn't get the additional message. I wish they had just told us outright that we were savages and our world was stupid.”

“If you don't believe in the things you're doing, the answer isn't fooling yourself into thinking you believe it. If you don't believe in what you're doing, then you just shouldn't be doing it.”
