"An entirely honest man, in the severe sense of the word, exists no more than an entirely dishonest knave: the best and the worst are only approximations of those qualities. Who are those that never contradict themselves? yet honesty never contradicts itself: Who are those that always contradict themselves? yet knavery is mere self-contradiction. Thus the knowledge of man determines not the things themselves, but their proportions, the quan∣tum of congruities and incongruities."
