Theory and History. Людвиг фон Мизес

All facts are dependent upon and conditioned by their causes. No deviation from the necessary course of affairs is possible. Eternal law regulates everything.

      In this sense determinism is the epistemological basis of the human search for knowledge.¹ Man cannot even conceive the image of an undetermined universe. In such a world there could not be any awareness of material things and their changes. It would appear a senseless chaos. Nothing could be identified and distinguished from anything else. Nothing could be expected and predicted. In the midst of such an environment man would be as helpless as if spoken to in an unknown language. No action could be designed, still less put into execution. Man is what he is because he lives in a world of regularity and has the mental power to conceive the relation of cause and effect.

      Any epistemological speculation must lead toward determinism. But the acceptance of determinism raises some theoretical difficulties that have seemed to be insoluble. While no philosophy has disproved determinism, there are some ideas that people have not been able to bring into agreement with it. Passionate attacks have been directed against it because people believed that it must ultimately result in absurdity.

2 The Negation of Ideological Factors

      Many authors have assumed that determinism, fully implying consistent materialism, strictly denies that mental acts play any role in the course of events. Causation, in the context of the doctrine so understood, means mechanical causation. All changes are brought about by material entities, processes, and events. Ideas are just intermediary stages in the process through which a material factor produces a definite material effect. They have no autonomous existence. They merely mirror the state of the material entities that begot them. There is no history of ideas and of actions directed by them, only a history of the evolution of the real factors that engender ideas.

      From the point of view of this integral materialism, the only consistent materialist doctrine, the customary methods of historians and biographers are to be rejected as idealistic nonsense. It is vain to search for the development of certain ideas out of other previously held ideas. For example, it is “unscientific” to describe how the philosophical ideas of the seventeenth and eighteenth centuries evolved out of those of the sixteenth century. “Scientific” history would have to describe how out of the real—physical and biological—conditions of each age its philosophical tenets necessarily spring. It is “unscientific” to describe as a mental process the evolution of Saint Augustine’s ideas that led him from Cicero to Manichaeus and from Manichaeism to Catholicism. The “scientific” biographer would have to reveal the physiological processes that necessarily resulted in the corresponding philosophical doctrines.

      The examination of materialism is a task to be left to the following chapters. At this point it is enough to establish the fact that determinism in itself does not imply any concessions to the materialist standpoint. It does not negate the obvious truth that ideas have an existence of their own, contribute to the emergence of other ideas, and influence one another. It does not deny mental causation and does not reject history as a metaphysical and idealistic illusion.

3 The Free-Will Controversy

      Man chooses between modes of action incompatible with one another. Such decisions, says the free-will doctrine, are basically undetermined and uncaused; they are not the inevitable outcome of antecedent conditions. They are rather the display of man’s inmost disposition, the manifestation of his indelible moral freedom. This moral liberty is the essential characteristic of man, raising him to a unique position in the universe.

      Determinists reject this doctrine as illusory. Man, they say, deceives himself in believing that he chooses. Something unknown to the individual directs his will. He thinks that he weighs in his mind the pros and cons of the alternatives left to his choice and then makes a decision. He fails to realize that the antecedent state of things enjoins on him a definite line of conduct and that there is no means to elude this pressure. Man does not act, he is acted upon.

      Both doctrines neglect to pay due attention to the role of ideas. The choices a man makes are determined by the ideas that he adopts.

      

      The determinists are right in asserting that everything that happens is the necessary sequel of the preceding state of things. What a man does at any instant of his life is entirely dependent on his past, that is, on his physiological inheritance as well as on all he went through in his previous days. Yet the significance of this thesis is considerably weakened by the fact that nothing is known about the way in which ideas arise. Determinism is untenable if based upon or connected with the materialist dogma.² If advanced without the support of materialism, it says little indeed and certainly does not sustain the determinists’ rejection of the methods of history.

      The free-will doctrine is correct in pointing out the fundamental difference between human action and animal behavior. While the animal cannot help yielding to the physiological impulse which prevails at the moment, man chooses between alternative modes of conduct. Man has the power to choose even between yielding to the most imperative instinct, that of self-preservation, and the aiming at other ends. All the sarcasms and sneers of the positivists cannot annul the fact that ideas have a real existence and are genuine factors in shaping the course of events.

      The offshoots of human mental efforts, the ideas and the judgments of value that direct the individuals’ actions, cannot be traced back to their causes, and are in this sense ultimate data. In dealing with them we refer to the concept of individuality. But in resorting to this notion we by no means imply that ideas and judgments of value spring out of nothing by a sort of spontaneous generation and are in no way connected and related to what was already in the universe before their appearance. We merely establish the fact that we do not know anything about the mental process which produces within a human being the thoughts that respond to the state of his physical and ideological environment.

      This cognition is the grain of truth in the free-will doctrine. However, the passionate attempts to refute determinism and to salvage the notion of free will did not concern the problem of individuality. They were prompted by the practical consequences to which, as people believed, determinism inevitably leads: fatalist quietism and absolution from moral responsibility.

4 Foreordination and Fatalism

      As theologians teach, God in his omniscience knows in advance all the things that will happen in the universe for all time to come. His foresight is unlimited and is not merely the result of his knowledge of the laws of becoming that determine all events. Even in a universe in which there is free will, whatever this may be, his precognition is perfect. He anticipates fully and correctly all the arbitrary decisions any individual will ever make.

      Laplace proudly declared that his system does not need to resort to the hypothesis of God’s existence. But he constructed his own image of a quasi God and called it superhuman intelligence. This hypothetical mind knows all things and events beforehand, but only because it is familiar with all the immutable and eternal laws regulating all occurrences, mental as well as physical.

      The idea of God’s omniscience has been popularly pictured as a book in which all future things are recorded. No deviation from the lines described in this register is possible. All things will turn out precisely as written in it. What must happen will happen no matter what mortal man may undertake to bring about a different result. Hence, consistent fatalism concluded, it is useless for man to act. Why bother if everything must finally come to a preordained end?

      Fatalism is so contrary to human nature that few people were prepared to draw all the conclusions to which it leads and to adjust
