I bought this book for my son last year, and ended up reading it and going through it myself as I start to think more about collective intellligence, five minds, group IQ and such. Dissent and diversity are so important to all of us, that I am moved to suggest this book--which Amazon is offering at a price way below its actual value--as the perfect Christmas present for any college student or any adult.
Start at the end of the book, with the interview of Milton Glaser by Steven Hellor, "Dissenting Conditions," and the directory of contributors.
I think this book is a classic work, and I hope the publisher will issue an updated or follow on version at least every five years.
This is a GEM of a book.
