"I saw the bloodiest, grimiest side of human nature," LaVey recounted in a session dealing with his past life. "People shot by nuts, knifed by their friends; little kids splattered in the gutter by hit-and-run drivers. It was disgusting and depressing. I asked myself: 'Where is God?' I came to detest the sanctimonious attitude of people toward violence, always saying 'it's God's will'."

So he quit in disgust after three years of being a crime photographer and returned to playing organ, this time in nightclubs and theaters to earn a living while he continued his studies into his life's passion: the black arts. Once a week he held classes on arcane topics: hauntings, E.S.P., dreams, vampires, werewolves, divination, ceremonial magic, etc. They attracted many people who were, or have since become, well known in the arts and sciences, and the business world. Eventually a "Magic Circle" evolved from this group.

The major purpose of the Circle was to meet for the performance of magical rituals LaVey had discovered or devised. He had accumulated a library of works that descibed the Black Mass and other infamous ceremonies conducted by groups such as the Knights Templar in fourteenth-century France, the Hell-Fire club and the Golden Dawn in eighteenth- and nineteenth-century England. The intent of some of these secret orders was to blaspheme, lampoon the Christian church, and address themselves to the Devil as an anthropomorphic deity that represented the reverse of God. In LaVey's view, the Devil was not that, but rather a dark, hidden force in nature responsible for the workings of earthly affairs, a force for which neither science nor religion had any explanation. LaVey's Satan is "the spirit of progress, the inspirer of all great movements that contribute to the development of civilization and the advancement of mankind. He is the spirit of revolt that leads to freedom, the embodiment of all heresies that liberate."
