many a man has overcome cowardice, or lust, or ill-temper, by learning to think that they are beneath his dignity—that is, by Pride.

Context

“consequently it is far more subtle and deadly. For the same reason, Pride can often be used to beat down the simpler vices. Teachers, in fact, often appeal to a boy’s Pride, or, as they call it, his self-respect, to make him behave decently: many a man has overcome cowardice, or lust, or ill-temper, by learning to think that they are beneath his dignity—that is, by Pride. The devil laughs. He is perfectly content to see you becoming chaste and brave and self-controlled provided, all the time, he is setting up in you the Dictatorship of Pride—just as he would be quite content to see your chilblains cured if he was allowed, in return, to give you cancer.” source
