In 50 years - or 20 years, or 200 years - our current epistemic horizon (the Big Bang, roughly) may look as parochial as the horizon Newton had to settle for in his day, but no doubt there will still be good questions whose answers elude us.

There may be things that are completely unknowable to us, so we must be careful not to treat the limits of our knowledge as sure guides to the limit of what there is.

Go ahead and believe in God , if you like, but don't imagine that you have been given any grounds for such a belief by science.

I look around the world and see so many wonderful things that I love and enjoy and benefit from, whether it's art or music or clothing or food and all the rest. And I'd like to add a little to that goodness.

I am a philosopher, not a scientist, and we philosophers are better at questions than answers.

Cults and prophets proclaiming the imminent end of the world have been with us for several millennia, and it has been another sour sort of fun to ridicule them the morning after, when they discover that their calculations were a little off.
