The Edge Annual Question — 2006
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. 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?
Roger Schank, Psychologist & Computer Scientist; Chief Learning Officer, Trump University; and Author of Making Minds Less Well Educated than Our Own, contributed an essay entitled No More Teacher's Dirty Looks which is an interesting summary of anti-schooling thought throughout the last two centuries.
By the way, the other 118 "dangerous ideas" are equally worth pondering.
