The Moral Landscape: How Science Can Determine Human Values by Sam Harris
"A lively, provocative, and timely new look at one of the deepest problems in the world of ideas. Harris makes a powerful case for a morality that is based on human flourishing and thoroughly enmeshed with science and rationality. It is a tremendously appealing vision, and one that no thinking person can afford to ignore." - Steven Pinker, Professor of Psychology at Harvard University, author of How the Mind Works and The Blank Slate
