The whole controversy is, however, meaningless when applied to praxeology. It refers essentially to geometry. Its present state, especially its treatment by logical positivism, has been deeply influenced by the shock that Western philosophy received from the discovery of non-Euclidian geometries. Before Bolyai and Lobachevsky, geometry was, in the eyes of the philosophers, the paragon of perfect science; it was assumed that it provided unshakable certainty forever and for everybody. To proceed also in other branches of knowledge more geometrico was the great ideal of truth-seekers. All traditional epistemological concepts began to totter when the attempts to construct non-Euclidian geometries succeeded.
Yet praxeology is not geometry. It is the worst of all superstitions to assume that the epistemological characteristics of one branch of knowledge must necessarily be applicable to any other branch. In dealing with the epistemology of the sciences of human action, one must not take one’s cue from geometry, mechanics, or any other science.
The assumptions of Euclid were once considered as self-evidently true. Present-day epistemology looks upon them as freely chosen postulates, the starting point of a hypothetical chain of reasoning. Whatever this may mean, it has no reference at all to the problems of praxeology.
The starting point of praxeology is a self-evident truth, the cognition of action, that is, the cognition of the fact that there is such a thing as consciously aiming at ends. There is no use cavilling about these words by referring to philosophical problems that have no bearing upon our problem. The truth of this cognition is as self-evident and as indispensable for the human mind as is the distinction between A and non-A.
5 The Reality of the External World
From the praxeological point of view it is not possible to question the real existence of matter, of physical objects and of the external world. Their reality is revealed by the fact that man is not omnipotent. There is in the world something that offers resistance to the realization of his wishes and desires. Any attempt to remove by a mere fiat what annoys him and to substitute a state of affairs that suits him better for a state of affairs that suits him less is vain. If he wants to succeed, he must proceed according to methods that are adjusted to the structure of something about which perception provides him with some information. We may define the external world as the totality of all those things and events that determine the feasibility or unfeasibility, the success or failure, of human action.
The much discussed question whether physical objects can or cannot be conceived as existing independently of the mind is vain. For thousands of years the minds of physicians did not perceive germs and did not divine their existence. But the success or failure of their endeavors to preserve their patients’ health and lives depended on the way germs influenced or did not influence the functioning of the patients’ bodily organs. The germs were real because they conditioned the outcome of events either by interfering or by not interfering, either by being present in or by being absent from the field.
Action is a category that the natural sciences do not take into account. The scientist acts in embarking upon his research work, but in the orbit of natural events of the external world which he explores there is no such thing as action. There is agitation, there is stimulus and response, and, whatever some philosophers may object, there is cause and effect. There is what appears to be an inexorable regularity in the concatenation and sequence of phenomena. There are constant relations between entities that enable the scientist to establish the process called measurement. But there is nothing that would suggest aiming at ends sought; there is no ascertainable purpose.
The natural sciences are causality research; the sciences of human action are teleological. In establishing this distinction between the two fields of human knowledge, we do not express any opinion concerning the question whether the course of all cosmic events is or is not ultimately determined by a superhuman being’s design. The treatment of this great problem transcends the range of man’s reason and is outside the domain of any human science. It is in the realm that metaphysics and theology claim for themselves.
The purpose to which the sciences of human action refer is not the plans and ways of God, but the ends sought by acting men in the pursuit of their own designs. The endeavors of the metaphysical discipline commonly called philosophy of history to reveal in the flux of historical events the hidden plans of God or of some mythical agency (as, for instance, in the scheme of Marx, the material productive forces) are not science.
In dealing with a definite historical fact, for instance with the first World War, the historian has to find out the ends sought by the various individuals and groups of individuals who were instrumental in organizing these campaigns or in fighting the aggressors. He has to examine the outcome resulting from the actions of all people involved and compare it with the preceding state of affairs as well as with the intentions of the actors. But it is not the historian’s business to search after a “higher” or “deeper” sense that manifested itself in the events or was realized by them. Perhaps there is such a hidden “higher” or “deeper” purpose or significance in the succession of historical events. But for mortal man there is no way open to learn something about such “higher” or “deeper” meanings.
All the elements of the theoretical sciences of human action are already implied in the category of action and have to be made explicit by expounding its contents. As among these elements of teleology is also the category of causality, the category of action is the fundamental category of epistemology, the starting point of any epistemological analysis.
The very category or concept of action comprehends the concepts of means and ends, of preferring and putting aside, viz., of valuing, of success and failure, of profit and loss, of costs. As no action could be devised and ventured upon without definite ideas about the relation of cause and effect, teleology presupposes causality.
Animals are forced to adjust themselves to the natural conditions of their environment; if they do not succeed in this process of adjustment, they are wiped out. Man is the only animal that is able—within definite limits—to adjust his environment purposively to suit him better.
We can think of the evolutionary process that transformed the nonhuman ancestors of mankind into human beings as a succession of small, gradual changes spread over millions of years. But we cannot think of a mind in which the category of action would have been present only in an incomplete form. There is nothing in between a being driven exclusively by instincts and physiological impulses and a being that chooses ends and the means for the attainment of these ends. We cannot think of an acting being that would not in concreto distinguish what is end and what is means, what is success and what is failure, what he likes more and what he likes less, what is his profit or his loss derived from the action and what his costs are. In grasping all these things, he may, of course, err in his judgments concerning the role various external events and materials play in the structure of his action.
A definite mode of behavior is an action only if these distinctions are present in the mind of the man concerned.
