"For the reader who seeks to understand happiness, my advice is: Begin with Haidt." --Martin E. P. Seligman, author of Authentic Happiness In his widely praised book, award-winning psychologist Jonathan Haidt examines the world's philosophical wisdom through the lens of psychological science, showing how a deeper understanding of enduring maxims--like "do unto others as you would have others do unto you," or "what doesn't kill you makes you stronger"--can enrich and even transform our lives.
