How should we live? This ancient question has a modern urgency. In the affluent West, society is changing faster than we can adjust to it. Online culture has transformed how we fall in love and nurture our friendships. The demise of the job for life, and rising expectations of finding work that broadens our horizons as well as pays the bills, have increased our confusion about choosing the right career. Medical progress has given us longer lives than ever before, and we are left wondering how best to spend the precious extra years we have been granted. Ecological crises are posing new challenges for ethical living, from where we take our holidays to how we think about our children’s future. Moreover, the quest for consumer pleasures and material wealth, which obsessed us during the twentieth century, has left many yearning for deeper forms of fulfilment and meaning. How to pursue the art of living has become the great quandary of our age.
