What is your dangerous idea?

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 examples. Here, leading thinkers discuss ideas -- whether they originally thought of them or not -- that are dangerous not because they’re false, but because they’re potentially true. From using medication to change our personalities to contemplating a universe in which we are utterly alone to the idea that the world might be fundamentally inexplicable, What Is Your Dangerous Idea? takes an unflinching look at thoughts that could -- very soon -- change the world and the way we live in it.
