The Happiness Hypothesis: Finding Modern Truth in Ancient Wisdom

The Happiness Hypothesis: Finding Modern Truth in Ancient Wisdom is a 2006 psychology book written by Jonathan Haidt for a general audience. In it, Haidt poses several "Great Ideas" on happiness espoused by thinkers of the past—Plato, Buddha, Jesus, and others—and examines them in the light of contemporary psychological research, extracting from them any lessons that still apply to our modern lives. Central to the book are the concepts of virtue, happiness, fulfillment, and meaning.
