Happiness comes from within. Can these 'truths' hold the key to a happier, more fulfilled life?In The Happiness Hypothesis, social psychologist Jonathan Haidt examines ten Great Ideas which have been championed across centuries and civilisations and asks: how can we apply these ideas to our twenty-first century lives?

Why can it sometimes feel as though half the population is living in a moral universe? Why do ideas such as 'fairness' and 'freedom' mean such different things to different people? Why is it so hard to see things from another viewpoint? Why do we come to blows over politics and religion? This book answers these questions about human relationships.
