What is Your Dangerous Idea? Edited by John Brockman

I've been dipping in and out of this collection of essays written by Today's Leading Thinkers who are, apparently, people like Daniel C Dennett, Susan Blackmore and Stephen Pinker. It's not bad, but I've heard most of these arguments before. The authors agonise over stuff like the non-existence of the soul, human inequality, eugenics, free will, consciousness, and the general pointlessnes of the universe. Actually it was quite depressing. Today's Leading Thinkers seem to do a lot of worrying and don't have a lot of answers.
