Youth is not an essential, but rather an accidental property. Nobody is in essence young. One either ceases to be or ceases to be young.

What is love? When you love somebody then I mean we all want good things to happen to ourselves and keep the bad things at bay. When you love somebody you want that as much for them if not more than you do for yourself.

Philosophy is this amazing technique we've devised for getting reality to answer us back when we're getting it wrong. Science itself can't make those arguments. You actually have to rely on philosophy, on philosophy of science.

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.

Plato conceived of philosophy as necessarily gregarious rather than solitary. The exposure of presumptions is best done in company, the more argumentative the better.

For the ancient Greeks, who lacked our social media, the only way to achieve mass duplication of the details of one's life in the apprehension of others was to do something wondrously worth the telling. Our wondrous technologies might just save us all the personal bother. Kleos is a tweak away.

I like that there are so many different ways of looking at the world and I like all of the particular narratives. In any case we will never all see the same way on these [religious] issues. It's the way liberals and conservatives will never see the same way on individuals whereas it’s different orientations and they go too deep down and when we're dealing with questions that can't be definitively answered by science that's where you're sort of... your orientation swells in to fill up the gaps and so we're never always going to agree.
