“I want to make it as clear as I possibly can that the centre of Christian morality is  not sexual morality. If anyone thinks that Christians regard unchastity as the supreme
vice, he is quite wrong. The sins of the flesh are bad, but they are the  least bad of all
sins. All the worst pleasures are purely spiritual: the pleasure of putting other people in
the wrong, of bossing and patronizing and spoiling sport, and back-biting; the
pleasures of power, of hatred.
For there are two things inside me, competing with the human self which I must try to
become. They are the Animal self, and the Diabolical self. The Diabolical self is the
worse of the two. That is why a cold, self-righteous prig who goes regularly to church
may be far nearer to hell than a prostitute. But, of course, it is better to be neither...”
