The third argument asserts that universal causation is incompatible with responsibility. But what do we mean by responsibility? Nothing but the fact that society, if it can do so, will punish its members for certain deeds. Why should a belief in universal causation prevent society from punishing its members? Bismarck writes in a letter to his sister: “It is not the wolf’s fault that God has created him as he is. That does not prevent us from killing him whenever we can.” Holding a person responsible, punishing or rewarding him, does not lose its meaning if we regard his actions as being determined by causes. We do not then hold him responsible for the single act, but for his being so natured that under such circumstances he cannot help committing such a deed. The question becomes this: What is the more plausible reason for punishing a person, his abnormal deed or his abnormal, unsocial nature which made this deed possible? It is true that punishment dealt out by an individual or a small group is often merely an instinctive act of revenge for a single deed. If a person beats me, do I have less pain if I beat him and cause him pain too? Should a gambler beat the roulette because it makes him lose and the other man gain? Would the roulette act differently for having been beaten? Am I sure that the person whose beating me was undetermined by causes will treat me better the next time? If his actions are caused, he probably will treat me better because the memory of the blows received from me will act as a cause. The instinct of returning blows would be incomprehensible if human action were independent of causes. But the legal punishment dealt out by the officers of a nation has lost the significance of an instinctive act of revenge. Does this fact make it compatible with the doctrine of causeless activity? Would not punishment, under this doctrine, be cruelty pure and simple? Punishment can be justified only if it can act as a cause determining human behavior. Society introduces fear of threatened punishment and memory of suffered punishment as motives into the mental life of its members, in order to inhibit criminal actions in those who are so natured that they will commit acts inimical to society when occasion offers, or when they are tempted. The degree of the penalty is adapted to the effectiveness of the temptation under different circumstances. Children and intoxicated and insane persons are treated in a different manner because the fundamental condition of punishment--the existence of an idea of punishment capable of serving as a motive of action--is not fulfilled in them. All this becomes entirely purposeless, meaningless, if we accept the doctrine that human actions are not completely determined by causes. Responsibility, social order, and law, far from being called in question by determinism, are, on the contrary, dependent on it for their justification.
