The concern for the well-being of others could be the saving grace of the 21st century. Matthieu Ricard’s Altruism, an erudite, brilliantly ranging synthesis of philosophy, psychology and ages old wisdom, is a radical call to kindness, which has the potential as a new global movement to answer the biggest problems of our time: the economy in the short term, life satisfaction in the mid-term, and the environment in the long term.

As the faultlines of inequality and nationalism leave us ever more divided, Ricard challenges us to be better people - and in the process, make the world a better place.
