      Mortal man does not know how the universe and all that it contains may appear to a superhuman intelligence. Perhaps such an exalted mind is in a position to elaborate a coherent and comprehensive monistic interpretation of all phenomena. Man—up to now, at least—has always gone lamentably amiss in his attempts to bridge the gulf that he sees yawning between mind and matter, between the rider and the horse, between the mason and the stone. It would be preposterous to view this failure as a sufficient demonstration of the soundness of a dualistic philosophy. All that we can infer from it is that science—at least for the time being—must adopt a dualistic approach, less as a philosophical explanation than as a methodological device.

      Methodological dualism refrains from any proposition concerning essences and metaphysical constructs. It merely takes into account the fact that we do not know how external events—physical, chemical, and physiological—affect human thoughts, ideas, and judgments of value. This ignorance splits the realm of knowledge into two separate fields, the realm of external events, commonly called nature, and the realm of human thought and action.

      Older ages looked upon the issue from a moral or religious point of view. Materialist monism was rejected as incompatible with the Christian dualism of the Creator and the creation, and of the immortal soul and the mortal body. Determinism was rejected as incompatible with the fundamental principles of morality as well as with the penal code. Most of what was advanced in these controversies to support the respective dogmas was unessential and is irrelevant from the methodological point of view of our day. The determinists did little more than repeat their thesis again and again, without trying to substantiate it. The indeterminists denied their adversaries’ statements but were unable to strike at their weak points. The long debates were not very helpful.

      The scope of the controversy changed when the new science of economics entered the scene. Political parties which passionately rejected all the practical conclusions to which the results of economic thought inevitably lead, but were unable to raise any tenable objections against their truth and correctness, shifted the argument to the fields of epistemology and methodology. They proclaimed the experimental methods of the natural sciences to be the only adequate mode of research, and induction from sensory experience the only legitimate mode of scientific reasoning. They behaved as if they had never heard about the logical problems involved in induction. Everything that was neither experimentation nor induction was in their eyes metaphysics, a term that they employed as synonymous with nonsense.

2 Economics and Metaphysics

      The sciences of human action start from the fact that man purposefully aims at ends he has chosen. It is precisely this that all brands of positivism, behaviorism, and panphysicalism want either to deny altogether or to pass over in silence. Now, it would simply be silly to deny the fact that man manifestly behaves as if he were really aiming at definite ends. Thus the denial of purposefulness in man’s attitudes can be sustained only if one assumes that the choosing both of ends and of means is merely apparent and that human behavior is ultimately determined by physiological events which can be fully described in the terminology of physics and chemistry.

      Even the most fanatical champions of the “Unified Science” sect shrink from unambiguously espousing this blunt formulation of their fundamental thesis. There are good reasons for this reticence. So long as no definite relation is discovered between ideas and physical or chemical events of which they would occur as the regular sequel, the positivist thesis remains an epistemological postulate derived not from scientifically established experience but from a metaphysical world view.

      The positivists tell us that one day a new scientific discipline will emerge which will make good their promises and will describe in every detail the physical and chemical processes that produce in the body of man definite ideas. Let us not quarrel today about such issues of the future. But it is evident that such a metaphysical proposition can in no way invalidate the results of the discursive reasoning of the sciences of human action. The positivists for emotional reasons do not like the conclusions that acting man must necessarily draw from the teachings of economics. As they are not in a position to find any flaw either in the reasoning of economics or in the inferences derived from it, they resort to metaphysical schemes in order to discredit the epistemological foundations and the methodological approach of economics.

      There is nothing vicious about metaphysics. Man cannot do without it. The positivists are lamentably wrong in employing the term “metaphysics” as a synonym for nonsense. But no metaphysical proposition must contradict any of the findings of discursive reasoning. Metaphysics is not science, and the appeal to metaphysical notions is vain in the context of a logical examination of scientific problems. This is true also of the metaphysics of positivism, to which its supporters have given the name of antimetaphysics.

3 Regularity and Prediction

      Epistemologically the distinctive mark of what we call nature is to be seen in the ascertainable and inevitable regularity in the concatenation and sequence of phenomena. On the other hand the distinctive mark of what we call the human sphere of history or, better, the realm of human action is the absence of such a universally prevailing regularity. Under identical conditions stones always react to the same stimuli in the same way; we can learn something about these regular patterns of reacting, and we can make use of this knowledge in directing our actions toward definite goals. Our classification of natural objects and our assigning names to these classes is an outcome of this cognition. A stone is a thing that reacts in a definite way. Men react to the same stimuli in different ways, and the same man at different instants of time may react in ways different from his previous or later conduct. It is impossible to group men into classes whose members always react in the same way.

      This is not to say that future human actions are totally unpredictable. They can, in a certain way, be anticipated to some extent. But the methods applied in such anticipations, and their scope, are logically and epistemologically entirely different from those applied in anticipating natural events, and from their scope.

4 The Concept of the Laws of Nature

      Experience is always experience of past happenings. It refers to what has been and is no longer, to events sunk forever in the flux of time.

      The awareness of regularity in the concatenation and sequence of many phenomena does not affect this reference of experience to something that occurred once in the past at a definite place and time under the circumstances
