“Most of our platitudes notwithstanding, self-deception remains the most difficult deception. The tricks that work on others count for nothing in that very well-lit back alley where one keeps assignation with oneself: no winning smiles will do here, no prettily drawn lists of good intentions. One shuffles flashily but in vain through one's marked cards- the kindness done for the wrong reason, the apparent triumph which involved no real effort, the seemingly heroic act into which one had been shamed.”
