The history of science is replete with discoveries that were considered socially, morally, or emotionally dangerous in their time; the Copernican and Darwinian revolutions are the most obvious. What is your dangerous idea? An idea you think about (not necessarily one you originated) that is dangerous not because it is assumed to be false, but because it might be true?
What you will find emerging out of the 119 original essays in the 75,000 word document written in response to the 2006 Edge Question — "What is your dangerous idea?" — are indications of a new natural philosophy, founded on the realization of the import of complexity, of evolution. Very complex systems — whether organisms, brains, the biosphere, or the universe itself — were not constructed by design; all have evolved. There is a new set of metaphors to describe ourselves, our minds, the universe, and all of the things we know in it.
