I have a Greek-American friend who named her daughter "Nike" and is often asked why she chose to name her offspring after a sneaker.

We may not need God to tell us where the world came from, but we need God to be able to live moral lives and for there to be morality in the first place.

Everybody is struggling to refine their views in opposition to the other people. And that's one of the most important things that philosophy actually has to teach us that you have to air your views and bring them to the table with people - with whom you disagree very much.

I think one reason is that philosophers are more insecure to speak accessibly because non-philosophers are skeptical that philosophers have any special expertise. After all, all people - not just philosophers - have attitudes and points of view on various philosophical questions, and they rather resent being told that there are professionals who can think about these things better.

Philosophers feel a little more cautious about letting down their technical guard lest the general public doesn't recognize their special credentials. It's the fact that philosophy is of general interest that, paradoxically, keeps philosophers from wanting to speak in a way that's accessible to the general public.

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.

Those who share my heroes are, in the deepest sense, of my own kind.
