Published in 1942, 'The Myth of Sisyphus' is Albert Camus's seminal philosophical essay that introduces the concept of 'The Absurd.' Camus defines the absurd as the conflict between the human innate desire for order, meaning, and reason, and the 'unreasonable silence' of an indifferent universe. The book famously opens with the claim that suicide is the only truly serious philosophical problem, as it forces one to judge whether life is worth living. Rather than succumbing to despair or seeking refuge in religious 'leaps of faith,' Camus argues for 'revolt'—the act of living consciously and passionately in spite of meaninglessness. He concludes with the metaphor of Sisyphus, the Greek figure condemned to roll a boulder up a hill for eternity, suggesting that the struggle itself provides sufficient fulfillment for the human heart.
