Naturally enough, Nietzsche was an earnest opponent of the theological doctrine of free will. He held, as we have seen, that every human act was merely the effect of the will to power reacting against environment, and in consequence he had to reject absolutely the notion of volition and responsibility. A man, he argued, was not an object _in vacuo_ and his acts, thoughts, impulses and motives could not be imagined without imagining some cause for them. If this cause came from without, it was clearly beyond his control, and if it came from within it was no less so, for his whole attitude of mind, his instinctive habits of thoughts, his very soul, so-called, were merely attributes that had been handed down to him, like the shape of his nose and the color of his eyes, from his ancestors. Nietzsche held that the idea of responsibility was the product and not the cause of the idea of punishment, and that the latter was nothing more than a manifestation of primitive man's will to power--to triumph over his fellows by making them suffer the handicap and humiliation of pain. "Men were called free," he said, "in order that they might be condemned and punished.... When we immoralists try to cleanse psychology, history, nature and sociology of these notions, we find that our chief enemies are the theologians, who, with their preposterous idea of 'a moral order of the world,' go on tainting the innocence of man's struggle upward with talk of punishment and guilt. Christianity is, indeed, a hangman's metaphysic."[9] As a necessary corollary of this, Nietzsche denied the existence of any plan in the cosmos. Like Haeckel, he believed that but two things existed--energy and matter; and that all the phenomena which made us conscious of the universe were nothing more than symptoms of the constant action of the one upon the other. Nothing ever happened without a cause, he said, and no cause was anything other than the effect of some previous cause. "The destiny of man," he said, "cannot be disentangled from the destiny of everything else in existence, past, present and future.... We are a part of the whole, we exist in the whole.... There is nothing which could judge, measure or condemn our being, for that would be to judge, measure and condemn the whole.... But there is nothing outside of the whole.... The concept of God has hitherto made our existence a crime.... We deny God, we deny responsibility by denying God: it is only thereby that we save man."[10]
