Wellcome! I've often wondered about atheistic Satanism's relation to magic and magical thinking, and/or atheism based of belief in scientific materialism.
I don't what truth is, but it's fun to think of "showman charlatan" LaVey jumpint out of his pants at the moment he realizes that magick really works... :)
Most of us believe in the psychological power of ritual practice, but not that ritual is inherently supernatural.
