“In "The Myth of Sisyphus", his most important non-fiction work, Albert Camus suggested that if we believed what most people claim to be the purpose of life, we would feel compelled to commit suicide. If, however, we accept that life has no purpose we would be inclined to soldier on in a cussed, stoical manner like Sisyphus, endlessly pushing his rock up a hill only to see it roll down again.”
