Great Quote: C.S. Lewis on Humility

The vice I am talking of 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, anger, greed, drunkenness, and all that, are
mere fleabites 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.
