Thinking is the soul speaking to itself.

So Socrates was a kind of gadfly. He was a sort of philosophical urban gorilla hanging around in the middle of Athens, asking these peculiar questions of everybody - important people, young men, slaves - questions that had to do with ultimately what's the life that's worth living. And Plato was one of the young men who hung around him, a very aristocratic young man, came from a very old, important family.

And what is it, according to Plato, that philosophy is supposed to do? Nothing less than to render violence to our sense of ourselves and our world, our sense of ourselves in the world.

I've got access to your mysterious body but not your mysterious soul. Souls seem to me the loneliest possibility of all.

Everybody have equal rights to a life of full flourishing. Philosophy slowly, slowly has given us arguments saying, look, you already committed to your own life flourishing, and you're being inconsistent if you don't expand it. So philosophy often works in trying to show us that there's an inner incoherence in our points of view. We're all committed to one thing when it comes to us and our own kind, but we're not willing to expand it and we're guilty of inconsistency.

There is nothing superstitious about forcing bad consequences for the hubris of paternalistic utopianism. Humanity should never be frozen into a vision of the best. A creative society must be willing to tolerate some degree of instability because creativity is inherently unstable.

That's one of the compensations for being mediocre. One doesn't have to worry about becoming mediocre.
