Pride is a vice we overlook in ourselves, but despise when we see it in
others.  There is one vice of which no man in the world is free; which
everyone in the world loathes when he sees it in someone else; and of
which hardly any people, except Christians ever imagine that they are
guilty themselves. . . .We cannot strive to be humble. A man is never so
proud as when striking an attitude of humility. . . .As long as one knows
one is proud one is safe from the worst form of pride.

                                       --C.S. Lewis
