A good player who loses at chess is genuinely convinced hat he has lost because of a mistake, and he looks for this mistake in the beginning of his game, but forgets that there were also mistakes at ever step in the course of the game, that none of his moves was perfect. The mistake he pays attention to is conspicuous only because his opponent took advantage of it.
Leo TolstoyHe had the unlucky capacity many men have of seeing and believing in the possibility of goodness and truth, but of seeing the evil and falsehood of life too clearly to take any serious part in it.
