Book excerpt: Human Nature offers a wide-ranging and holistic view of human nature from all perspectives: scientific, historical, and sociological. Mary Clark takes the most recent data from a dozen or more fields, and works it together with clarifying anecdotes and thought-provoking images to challenge conventional Western beliefs with hopeful new insights. Balancing the theories of cutting-edge neuroscience with the insights of primitive mythologies, Mary Clark provides down-to-earth suggestions for peacefully resolving global problems. Human Nature builds up a coherent, and above all positive, picture of who we really are.
