"Men believe in the truth of all that is seen to be strongly believed. In all great deceivers, a remarkable process is at work to which they owe their power. In the very act of deception with all its preparations—the dreadful voice, the expression, the gestures—they are overcome by their belief in themselves, and it is this belief which then speaks so persuasively, so miracle-like to the audience. Not only does he communicate that to the audience but the audience returns it to him and strengthens his belief." Friedrich Nietzsche, quoted by Ron Rosenbaum in his essay "Explaining Hitler" p. 735 The Secret Parts of Fortune (Random House 2000)
