Lucifer endears himself to us only as the Lord of Lies, for in this role he is most convincing as a character, which is to say, as a fiction that has been so fully realized that he misguides us with a false feeling of our own reality because we are the ones who made him: he is subordinate to us, especially in the art of lying. For the acephalics among us who have said that the Devil’s greatest trick was convincing the world that he did not exist, it must be said back: if he did not exist, then neither would we.
