The Sickness Unto Death (Søren Kierkegaard)

Influencing philosophers such as Sartre and Camus, and still strikingly modern in its psychological insights, Kierkegaard's The Sickness Unto Death explores the concept of 'despair' as a symptom of the human condition and describes man's struggle to fill the spiritual void.

Throughout history, some books have changed the world. They have transformed the way we see ourselves - and each other. They have inspired debate, dissent, war and revolution.
