There is nothing very odd about lambs disliking birds of prey, but this is no reason for holding it against large birds of prey that they carry off lambs. And when the lambs whisper among themselves, "These birds of prey are evil, and does this not give us a right to say that whatever is the opposite of a bird of prey must be good," there is nothing intrinsically wrong with such an argument-though the birds of prey will look somewhat quizzically and say, We have nothing against these good lambs; in fact, we love them; nothing tastes better than a tender lamb.
Friedrich NietzscheI can tell by my own reaction to it that this book is harmful." But let him only wait and perhaps one day he will admit to himself that this same book has done him a great service by bringing out the hidden sickness of his heart and making it visible.โ Altered opinions do not alter a manโs character (or do so very little); but they do illuminate individual aspects of the constellation of his personality which with a different constellation of opinions had hitherto remained dark and unrecognizable.
