Sade described himself as a martyr of atheism. Was this accurate? Did he live and die according to his beliefs? ‘Martyr of atheism’ looks at Sade's atheism and how he exhibited it in his thought and work. He rejected religious dogma and all of the social and moral interdictions that derive from it. It is because of his convictions to these beliefs that he spent so much of his life imprisoned. Sade was heavily influenced by material philosophy, especially the philosophy of La Mettrie and Paul-Henri d'Holbach. However, Sade is unique to atheistic philosophers of his time in that he had a material, physical awareness of the infinite.
