Aleister Crowley

Aleister Crowley (1875–1947), English magician, poet, philosopher, and artist, is widely regarded as one of the most important occult figures of the twentieth century. His famous and oft-misunderstood maxim "Do what thou wilt shall be the whole of the Law" stems from his received text The Book of the Law, which announced Thelema (Greek for "will") as the philosophy for a new era of humankind.
