Perhaps Sam is preaching to the choir a bit here, but it's a d@mn good sermon. This book effectively ended any debate left in my mind about the existence of free-will. I cannot stop thinking about the causes of other's, and my own, actions, and just how backward our punitive system is in the U.S.. Sam argues that accepting the non-existence of free-will can actually make you more forgiving, more productive, and happier (and, ironically, a bit more free). As usual, Harris has devoured a topic full of disagreement and significance and provided an entertaining and consciousness-raising thesis destined to warp your mind. Enjoy.
Much of the authors conclusion simply boils down to science can't measure free will therefore it doesn't exist.
As someone who has studied science the scientific perspective would be science has no way to measure free will therefore it is not a question for science.
