Query: A cornerstone for 21st century science and policy.

I came across the mention of The Blank Slate while reading Sam Harris' Moral Landscape with an intention of fine-tuning my opinion of human nature. This should have been the book I read first. Though I may not agree with all of the conclusions Pinker presents to his research, the amount of it and irrefutable evidence against social constructionism is something everyone can benefit from. I had many assuptions about human nature with a backround in Sociology and have found many of them to be shattered. Easily readable and a great sense of humor. It is certainly one of the most important books I've read. Should be mandatory reading for every human being.
