Theory and History. Людвиг фон Мизес

      The term “materialism” as applied in contemporary speech has two entirely different connotations.

      The first connotation refers to values. It characterizes the mentality of people who desire only material wealth, bodily satisfactions, and sensuous pleasures.

      The second connotation is ontological. It signifies the doctrine that all human thoughts, ideas, judgments of value, and volitions are the product of physical, chemical, and physiological processes going on in the human body. Consequently materialism in this sense denies the meaningfulness of thymology and the sciences of human action, of praxeology as well as of history; the natural sciences alone are scientific. We shall deal in this chapter only with this second connotation.

      The materialist thesis has never yet been proved or particularized. The materialists have brought forward no more than analogies and metaphors. They have compared the working of the human mind with the operation of a machine or with physiological processes. Both analogies are insignificant and do not explain anything.

      A machine is a device made by man. It is the realization of a design and it runs precisely according to the plan of its authors. What produces the product of its operation is not something within it but the purpose the constructor wanted to realize by means of its construction. It is the constructor and the operator who create the product, not the machine. To ascribe to a machine any activity is anthropomorphism and animism. The machine has no control over its running. It does not move; it is put into motion and kept in motion by men. It is a dead tool which is employed by men and comes to a standstill as soon as the effects of the operator’s impulse cease. What the materialist who resorts to the machine metaphor would have to explain first of all is: Who constructed this human machine and who operates it? In whose hands does it serve as a tool? It is difficult to see how any other answer could be given to this question than: It is the Creator.

      It is customary to call an automatic contrivance self-acting. This idiom too is a metaphor. It is not the calculating machine that calculates, but the operator by means of a tool ingeniously devised by an inventor. The machine has no intelligence; it neither thinks nor chooses ends nor resorts to means for the realization of the ends sought. This is always done by men.

      The physiological analogy is more sensible than the mechanistic analogy. Thinking is inseparably tied up with a physiological process. As far as the physiological thesis merely stresses this fact, it is not metaphorical; but it says very little. For the problem is precisely this, that we do not know anything about the physiological phenomena constituting the process that produces poems, theories, and plans. Pathology provides abundant information about the impairment or total annihilation of mental faculties resulting from injuries of the brain. Anatomy provides no less abundant information about the chemical structure of the brain cells and their physiological behavior. But notwithstanding the advance in physiological knowledge, we do not know more about the mind-body problem than the old philosophers who first began to ponder it. None of the doctrines they advanced has been either proved or disproved by newly won physiological knowledge.

      Thoughts and ideas are not phantoms. They are real things. Although intangible and immaterial, they are factors in bringing about changes in the realm of tangible and material things. They are generated by some unknown process going on in a human being’s body and can be perceived only by the same kind of process going on in the body of their author or in other human beings’ bodies. They can be called creative and original insofar as the impulse they give and the changes they bring about depend on their emergence. We can ascertain what we wish to about the life of an idea and the effects of its existence. About its birth we know only that it was engendered by an individual. We cannot trace its history further back. The emergence of an idea is an innovation, a new fact added to the world. It is, because of the deficiency of our knowledge, for human minds the origin of something new that did not exist before.

      What a satisfactory materialist doctrine would have to describe is the sequence of events going on in matter that produces a definite idea. It would have to explain why people agree or disagree with regard to definite problems. It would have to explain why one man succeeded in solving a problem which other people failed to solve. But no materialistic doctrine has up to now tried to do this.

      The champions of materialism are intent upon pointing out the untenability of all other doctrines that have been advanced for the solution of the mind-body problem. They are especially zealous in fighting the theological interpretation. Yet the refutation of a doctrine does not prove the soundness of any other doctrine at variance with it.

      Perhaps it is too bold a venture for the human mind to speculate about its own nature and origin. It may be true, as agnosticism maintains, that knowledge about these problems is forever denied to mortal men. But even if this is so, it does not justify the logical positivists’ condemning the questions implied as meaningless and nonsensical. A question is not nonsensical merely because it cannot be answered satisfactorily by the human mind.
