"The decay of decency in the modern age, the rebellion against law and good faith, the treatment of human beings as things, as the mere instruments of power and ambition, is without a doubt the consequence of the decay of the belief in man as something more than an animal animated by highly conditioned reflexes and chemical reactions. For, unless man is something more than that, he has no rights that anyone is bound to respect, and there are no limitations upon his conduct which he is bound to obey."
