I'm a Spinozist. I believe in reason. I think all the progress that we've made making this a better world have been because of reason and not religion. I think religion has been pulled along by reason and that's why we read The Bible now so differently, even believers.

I would say to anybody who thinks that all the problems in philosophy can be translated into empirically verifiable answers - whether it be a Lawrence Krauss thinking that physics is rendering philosophy obsolete or a Sam Harris thinking that neuroscience is rendering moral philosophy obsolete - that it takes an awful lot of philosophy - philosophy of science in the first case, moral philosophy in the second - even to demonstrate the relevance of these empirical sciences.

It was while I was studying philosophy that I came to understand. . . that it is no sign of moral or spiritual strength to believe that for which one has no evidence, neither a priori evidence as in math, nor a posteriori evidence as in science. . . . It's a violation almost immoral in its transgressiveness to shirk the responsibilities of rationality.

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's concern is not just an intellectual issue, but it is knitted with emotional life as well.

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.

Answers? Forget answers. The spectacle is all in the questions.
