What is the meaning of life? In the post-modern, post-religious scientific world, this question is becoming a preoccupation. But it also has a long history: many major figures in philosophy had something to say on the subject. This book begins with an historical overview of philosophers from Plato to Hegel and Marx who have believed in some sort of meaning of life, either in some supposed "other" world or in the future of this world. Young goes on to look at what happened when the traditional structures that provided life with meaning ceased to be believed.
