My son has been reading the existentialists, starting with Camus (of course, The Plague is quite relevant for more than one reason now). He recently moved on to Kierkegaard, who
took a form of Christianity as a solution to existential angst. I was reminded of a book I read probably 15 years ago, by Stephen Batchelor: Buddhism Without Beliefs (London: Bloomsbury 1997) which argued that the Buddha was concerned with addressing the existential issue of suffering not with metaphysics and beliefs. I couldn’t find my copy of this, and bought another, which I enjoyed reading even more than the first time.
