Never lose sight of the fact that all human felicity lies in man's imagination, and that he cannot think to attain it unless he heeds all his caprices. The most fortunate of persons is he who has the most means to satisfy his vagaries.
Donatien Alphonse Franois de Sade, better known as the Marquis de Sade and nicknamed the Divine Marquis (June 2, 1740 December 2, 1814), was a French aristocrat and writer of philosophy-laden and often violent pornography, as well as some strictly philosophical works. His is a philosophy of extreme freedom, unrestrained by ethics, religion or law, with the egotistical pursuit of personal pleasure being the highest principle. Much of his writing was done during the 29 years he was incarcerated.
