Creases down spine.

Recently many people have assumed that we are shaped by our environment: a blank slate waiting to be inscribed by upbringing and culture, with innate abilities playing little part. 'The Blank Slate' shows that this view denies the heart of our being: human nature. Violence is not just a product of society; male and female minds are different; the genes we give our children shape the more than our parenting practices. To acknowledge our nature, Pinker shows, is not to condone inequality or callousness, but ultimately to understand the very foundations of humanity.
