Anton Szandor LaVeyOn Saturday night, I would see men lusting after half-naked girls dancing at the carnival, and on Sunday morning when I was playing organ for tent-show evangelists at the other end of the carnival lot, I would see these same men sitting in the pews with their wives and children, asking God to forgive them and purge them of carnal desires. And the next Saturday they'd be back at the carnival or some other place of indulgence. I knew then that the Christian church thrives on hypocrisy, and that man's carnal nature will out no matter how much it is purged or scoured by any white-light religion.
Anton Szandor LaVeyAfter an inferior man has been taught a doctrine of superiority he will remain as inferior as he was before his lesson. He will merely assume himself to be superior, and attempt to employ his recently-learned tactics against his own kind, whom he will then consider his inferiors. With each inferior man enjoying what he considers his unique role, the entire bunch will be reduced to a pack of strutting, foppish, self-centered monkeys gamboling about on an island of ignorance. There they will play their games under the supervision of their keeper, who was and always will be a superior man.
