"Lucifer began, mythologically, as a heavenly detective. He was the lawyer retained by the gods for the suppression of vice; and, from long engaging in that business, he came to love it. When he had nobody to accuse, he was in distress, and went about accusing innocent people. So he was called the Accuser. And then he fell lower still, and went about tempting people to sin, in order that he might prosecute them; and then he was called Satan. That was the course of the first Vice Society, and the end of its attorney."
