Dangerous ideas

From David Honigmann in The Financial Times:

Every year, the literary agent John Brockman invites 100 or so scientists and other thinkers to answer the "edge question". This year it was: "What is your dangerous idea?" In particular, respondents were asked for an idea that would be dangerous if it were true.

The results (collected at www.edge.org) give an insight into how philosophically minded scientists are thinking: the result is somewhere between a multi-disciplinary seminar and elevated high table talk.
