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?

Jonathan Haidt is the Thomas Cooley Professor of Ethical Leadership at New York University's Stern School of Business. He received his Ph.D. in social psychology from the University of Pennsylvania in 1992 and then did post-doctoral research at the University of Chicago and in Orissa, India. He taught at the University of Virginia for 16 years before moving to NYU-Stern in 2011. He was named one of the 'top global thinkers' by Foreign Policy magazine, and one of the 'top world thinkers' by Prospect magazine. His research focuses on morality - its emotional foundations, cultural variations and developmental course.
