The vice I am talking about is Pride or Self-Conceit: and the virtue opposite to it, in Christian morals, is called Humility. You may remember, when I was talking about sexual morality, I warned you that the centre of Christian morals did not lie there. Well, now we have come to the centre. According to Christian teachers, the essential vice, the utmost evil, is Pride. Unchastity, greed, drunkenness, and all that, are mere flea-bites in comparison: it was through Pride that the devil became the devil: Pride leads to every other vice: it is the complete anti-God state of mind.
