I love to try to understand first principles and be guided by that. But then, enrich them, because they won't last forever, just like everybody thought Newton had all the answers. And you probably read that, in the last of the 19th century, Harvard and others were discouraging people from going into physics because we have all the answers. And right after that, of course - we have - all this stuff is thrown out the window. And now we have whole new answers.

How do we have a society that maximizes peace, civility and well-being for everyone? How do we have a system of individual rights in which people succeed by helping others improve their lives? We're a long way from that. So what, I mean, we got more to learn than we know, to me. So we need better ideas.

Most power is power to coerce somebody. We don't have the power to coerce anybody.

If you have methods without principles, you're going to have trouble. But if you develop methods based on principles, then you can make progress.

Everything I give, pretty much, is public. Not every donor wants to - or is willing to get the kind of abuse and attacks that we do, or death threats, so they're not willing to have their names out. I think the other side is pushing for that because they want to intimidate people so they won't oppose it.

If there is wrong, you don't say we have to get rid of it gradually. If injustice exists, you need to eliminate it immediately.

Years later, when I asked my father, I said 'Pop, why were you so much harder on me than my younger brothers?' he said, son, you plum wore me out.
