Even geniuses change their minds sometimes. Edge, the influential online intellectual salon, recently asked 150 high-powered thinkers to discuss their most telling missteps and reconsiderations: What have you changed your mind about? The answers were brilliant, eye-opening, fascinating, sometimes shocking, and certain to kick-start countless passionate debates. Read Steven Pinker on the future of human evolution • Richard Dawkins on the mysteries of courtship • Sam Harris on the indifference of Mother Nature • Nassim Nicholas Taleb on the irrelevance of probability • Chris Anderson on the reality of global warming • Alan Alda on the existence of God • Lisa Randall on the secrets of the Sun • Ray Kurzweil on the possibility of extraterrestrial life • Brian Eno on what it means to be a "revolutionary" • Helen Fisher on love, fidelity, and the viability of marriage • Irene Pepperberg on learning from parrots. . . and many others. In this wide-ranging assortment of 150 brief essays, well-known figures from every conceivable field demonstrate why it's a prerogative of all thoughtful people to change their mind once in a while. Technologist Ray Kurzweil says he now shares Enrico Fermi's question: if other intelligent civilizations exist, then where are they? Nassim Nicholas Taleb (The Black Swan) reveals that he has lost faith in probability as a guiding light for making decisions. Oliver Morton (Mapping Mars) confesses that he has lost his childlike faith in the value of manned space flight to distant worlds. J. Craig Venter, celebrated for his work on the human genome, has ceased to believe that nature can absorb any abuses that we subject it to, and that world governments must move quickly to prevent global disaster. Alan Alda says, So far, I've changed my mind twice about God, going from believer to atheist to agnostic. Brockman, editor of Edge.org and numerous anthologies, has pulled together a thought-provoking collection of focused and tightly argued pieces demonstrating the courage to change strongly held convictions.
