The effects which follow too constant and intense a concentration upon evil are always disastrous. Those who crusade, not for God in themselves, but against the devil in others, never succeed in making the world better, but leave it either as it was, or sometimes even perceptibly worse than it was, before the crusade began. By thinking primarily of evil we tend, however excellent our intentions, to create occasions for evil to manifest itself.
Aldous HuxleyThe mockery made him feel an outsider; and feeling an outsider he behaved like one, which increased the prejudice against him and intensified the contempt and hostility aroused by his physical defects. Which in turn increased his sense of being alien and alone. A chronic fear of being slighted made him avoid his equals, made him stand, where his inferiors were concerned, self-consciously on his dignity.
