Epistemological Problems of Economics1

1. The Basic Concept of Action and its Categorial Conditions

The starting point of our reasoning is not behavior, but action, or, as it is redundantly designated, rational action. Human action is conscious behavior on the part of a human being. Conceptually it can be sharply and clearly distinguished from unconscious activity, even though in some cases it is perhaps not easy to determine whether given behavior is to be assigned to one or the other category.

As thinking and acting men, we grasp the concept of action. In grasping this concept we simultaneously grasp the closely correlated concepts of value, wealth, exchange, price, and cost. They are all necessarily implied in the concept of action, and together with them the concepts of valuing, scale of value and importance, scarcity and abundance, advantage and disadvantage, success, profit, and loss. The logical unfolding of all these concepts and categories in systematic derivation from the fundamental category of action and the demonstration of the necessary relations among them constitutes the first task of our science. The part that deals with the elementary theory of value and price serves as the starting point in its exposition. There can be no doubt whatever concerning the aprioristic character of these disciplines.

The most general prerequisite of action is a state of dissatisfaction, on the one hand, and, on the other, the possibility of removing or alleviating it by taking action. (Perfect satisfaction and its concomitant, the absence of any stimulus to change and action, belong properly to the concept of a perfect being. This, however, is beyond the power of the human mind to conceive. A perfect being would not act.) Only this most general condition is necessarily implied in the concept of action. The other categorial conditions of action are independent of the basic concept; they are not necessary prerequisites of concrete action. Whether or not they are present in a particular case can be shown by experience only. But where they are present, the action necessarily falls under definite laws that flow from the categorial determinacy of these further conditions.

It is an empirical fact that man grows old and dies and that therefore he cannot be indifferent to the passage of time. That this has been man’s experience thus far without exception, that we do not have the slightest evidence to the contrary, and that scarcely any other experience points more obviously to its foundation in a law of nature — all this in no way changes its empirical character. The fact that the passage of time is one of the conditions under which action takes place is established empirically and not a priori. We can without contradiction conceive of action on the part of immortal beings who would never age. But in so far as we take into consideration the action of men who are not indifferent to the passage of time and who therefore economize time because it is important to them whether they attain a desired end sooner or later, we must attribute to their action everything that necessarily follows from the categorial nature of time. The empirical character of our knowledge that the passage of time is a condition of any given action in no way affects the aprioristic character of the conclusions that necessarily follow from the introduction of the category of time. Whatever follows necessarily from empirical knowledge — e.g., the propositions of the agio theory of interest — lies outside the scope of empiricism.

Whether the exchange of economic goods (in the broadest sense, which also includes services) occurs directly, as in barter, or indirectly, through a medium of exchange, can be established only empirically. However, where and in so far as media of exchange are employed, all the propositions that are essentially valid with regard to indirect exchange must hold true. Everything asserted by the quantity theory of money, the theory of the relation between the quantity of money and interest, the theory of fiduciary media, and the circulation-credit theory of the business cycle, then becomes inseparably connected with action. All these theorems would still be meaningful even if there had never been any indirect exchange; only their practical significance for our action and for the science that explains it would then have to be appraised differently. However, the heuristic importance of experience for the analysis of action is not to be disregarded. Perhaps if there had never been indirect exchange, we would not have been able to conceive of it as a possible form of action and to study it in all its ramifications. But this in no way alters the aprioristic character of our science.

These considerations enable us to assess critically the thesis that all or most of the doctrines of economics hold only for a limited period of history and that, consequently, theorems whose validity is thus limited historically or geographically should replace, or at least supplement, those of the universally valid theory. All the propositions established by the universally valid theory hold to the extent that the conditions that they presuppose and precisely delimit are given. Where these conditions are present, the propositions hold without exception. This means that these propositions concern action as such; that is, that they presuppose only the existence of a state of dissatisfaction, on the one hand, and the recognized possibility, on the other, of relieving this dissatisfaction by conscious behavior, and that, therefore, the elementary laws of value are valid without exception for all human action. When an isolated person acts, his action occurs in accordance with the laws of value. Where, in addition, goods of higher order are introduced into action, all the laws of the theory of imputation are valid. Where indirect exchange takes place, all the laws of monetary theory are valid. Where fiduciary media are created, all the laws of the theory of fiduciary media (the theory of credit) are valid. There would be no point in expressing this fact by saying that the doctrines of the theory of money are true only in those periods of history in which indirect exchange takes place. ...

4. The Distinction Between Means and Ends: The “Irrational”

Most of the objections raised against the science of action stem from a misconception of the distinction between means and ends. In the strict sense, the end is always the removal of a dissatisfaction. However, we can doubtless also designate as an end the attainment of that condition of the external world which brings about our state of satisfaction either directly or indirectly, or which enables us to perform, without further difficulties, the act through which satisfaction is to be obtained. If the removal of the feeling of hunger is the end sought, the procuring of food and its preparation for eating can also be considered as ends; if one seeks the removal of the feeling of cold as an end, the heating of one’s quarters can just as well be called an end. If additional measures are needed for the removal of dissatisfaction, then the attainment of any particular step along the way toward the desired final condition is also designated as an end. In this sense the acquisition of money in the market economy and, proximately, the division of labor are designated as ends of action; in this sense too the attainment of all things that indirectly promote the end of want-satisfaction appear as proximate or intermediate ends.

In the course of attaining the primary end, secondary ends are attained. A man walks from A to B. He would choose the shortest route if other, secondary ends did not demand satisfaction. He makes a detour if he can walk in the shade a little longer; if he can include in his walk another place, C, which he wants to look for; if, by doing so, he can avoid dangers that may be lying in wait for him on the shortest route; or if he just happens to like the longer route. If he decides on a detour, we must infer that at the moment of decision the attainment of such secondary ends was of greater importance in his judgment than the saving of distance. Consequently, for him the “detour” was no detour at all, since his walk brought him greater satisfaction or — at least from the point of view that he took of his situation at the moment of decision — was expected to bring greater satisfaction than the attainment of his destination by the shorter route. Only one who does not have these secondary ends in mind can call the longer way a detour. As far as our stroller was concerned, it was the correct route, that is, the route that promised the greatest satisfactions.2

Since satisfaction and dissatisfaction depend only on the subjective view of the individual, there is no room for argument on this question in a science that does not presume to establish a scale of values or to make judgments of value. Its conception of an end, in the strict sense, is more deductive than empirical: ends are determined by the wishes and the desires of the individual. Whenever reference is made to the greater or lesser appropriateness of means, this can only be from the point of view of the acting individual.

We must next deal with the objection of those who never weary of asserting that man does not act rationally at all. It has never been disputed that man does not always act correctly from the objective point of view; that is, that either from ignorance of causal relations or because of an erroneous judgment of the given situation, in order to realize his ends he acts differently from the way in which he would act if he had correct information. In 1833 the method of healing wounds was different from that used in 1933, and in 2033 still another way will presumably be thought suitable. Statesmen, field marshals, and stock-market speculators act differently at present from the way in which they would act if they knew exactly all the data needed for an accurate judgment of conditions. Only a perfect being, whose omniscience and omnipresence would enable him to survey all the data and every causal relationship, could know how each erring human being would have to act at every moment if he wanted to possess the divine attribute of omniscience. If we were to attempt to distinguish rational action from irrational action, we should not only be setting ourselves up as a judge over the scales of value of our fellow men, but we should also be declaring our own knowledge to be the only correct, objective standard of knowledge. We should be arrogating to ourselves the position that only an all-knowing being has the power to occupy.

The assertion that there is irrational action is always rooted in an evaluation of a scale of values different from our own. Whoever says that irrationality plays a role in human action is merely saying, that his fellow men behave in a way that he does not consider correct. If we do not wish to pass judgment on the ends and the scales of value of other people and to claim omniscience for ourselves, the statement, “He acts irrationally,” is meaningless, because it is not compatible with the concept of action. The “seeking to attain an end” and the “striving after a goal” cannot be eliminated from the concept of action. Whatever does not strive after goals or seek the attainment of ends reacts with absolute passivity to an external stimulus and is without a will of its own, like an automaton or a stone. To be sure, man too is as far outside the effective range of his action as a reed in the wind. But in so far as he is able to do anything, he always acts: even negligence and passivity are action if another course of conduct could have been chosen. And the conduct that is determined by the unconscious, in the Freudian sense, or by the subconscious, is also action in so far as conscious behavior could prevent it but neglects to do so. Even in the unconscious and apparently senseless behavior of the neurotic and the psychopath there is meaning, i.e., there is striving after ends and goals.3

Everything that we say about action is independent of the motives that cause it and of the goals toward which it strives in the individual case. It makes no difference whether action springs from altruistic or from egoistic motives, from a noble or from a base disposition; whether it is directed toward the attainment of materialistic or idealistic ends; whether it arises from exhaustive and painstaking deliberation or follows fleeting impulses and passions. The laws of catallactics that economics expounds are valid for every exchange regardless of whether those involved in it have acted wisely or unwisely or whether they were actuated by economic or noneconomic motives. The causes of action and the goals toward which it strives are data for the theory of action: upon their concrete configuration depends the course of action taken in the individual case, but the nature of action as such is not thereby affected.

These considerations have an evident bearing on the widespread tendency of the present age to appeal to the irrational. The concepts rational and irrational are not applicable to ends at all. Whoever wishes to pass judgment on ends may praise or condemn them as good or evil, fine or vulgar, etc. When the expressions “rational” and “irrational” are applied to the means employed for the attainment of an end, such a usage has significance only from the standpoint of a definite technology. However, the use of means other than those prescribed as “rational” by this technology can be accounted for in only two possible ways: either the “rational” means were not known to the actor, or he did not employ them because he wished to attain still other ends — perhaps very foolish ones from the point of view of the observer. In neither of these two cases is one justified in speaking of “irrational” action.

Action is, by definition, always rational. One is unwarranted in calling goals of action irrational simply because they are not worth striving for from the point of view of one’s own valuations. Such a mode of expressions leads to gross misunderstandings. Instead of saying that irrationality plays a role in action, one should accustom oneself to saying merely: There are people who aim at different ends from those that I aim at, and people who employ different means from those I would employ in their situation.

Human Action5

1. Purposeful Action and Animal Reaction

Human action is purposeful behavior. Or we may say: Action is will put into operation and transformed into an agency, is aiming at ends and goals, is the ego’s meaningful response to stimuli and to the conditions of its environment, is a person’s conscious adjustment to the state of the universe that determines his life. Such paraphrases may clarify the definition given and prevent possible misinterpretations. But the definition itself is adequate and does not need complement or commentary.

Conscious or purposeful behavior is in sharp contrast to unconscious behavior, i.e., the reflexes and the involuntary responses of the body’s cells and nerves to stimuli. People are sometimes prepared to believe that the boundaries between conscious behavior and the involuntary reaction of the forces operating within man’s body are more or less indefinite. This is correct only as far as it is sometimes not easy to establish whether concrete behavior is to be considered voluntary or involuntary. But the distinction between consciousness and unconsciousness is nonetheless sharp and can be clearly determined.

The unconscious behavior of the bodily organs and cells is for the acting ego no less a datum than any other fact of the external world. Acting man must take into account all that goes on within his own body as well as other data, e.g., the weather or the attitudes of his neighbors. There is, of course, a margin within which purposeful behavior has the power to neutralize the working of bodily factors. It is feasible within certain limits to get the body under control. Man can sometimes succeed through the power of his will in overcoming sickness, in compensating for the innate or acquired insufficiency of his physical constitution, or in suppressing reflexes. As far as this is possible, the field of purposeful action is extended. If a man abstains from controlling the involuntary reaction of cells and nerve centers, although he would be in a position to do so, his behavior is from our point of view purposeful.

The field of our science is human action, not the psychological events which result in an action. It is precisely this which distinguishes the general theory of human action, praxeology, from psychology. The theme of psychology is the internal events that result or can result in a definite action. The theme of praxeology is action as such. This also settles the relation of praxeology to the psychoanalytical concept of the subconscious. Psychoanalysis too is psychology and does not investigate action but the forces and factors that impel a man toward a definite action. The psychoanalytical subconscious is a psychological and not a praxeological category. Whether an action stems from clear deliberation, or from forgotten memories and suppressed desires which from submerged regions, as it were, direct the will, does not influence the nature of the action. The murderer whom a subconscious urge (the Id) drives toward his crime and the neurotic whose aberrant behavior seems to be simply meaningless to an untrained observer both act; they like anybody else are aiming at certain ends. It is the merit of psychoanalysis that it has demonstrated that even the behavior of neurotics and psychopaths is meaningful, that they too act and aim at ends, although we who consider ourselves normal and sane call the reasoning determining their choice of ends nonsensical and the means they choose for the attainment of these ends contrary to purpose.

The term “unconscious” as used by praxeology and the term “subconscious” as applied by psychoanalysis belong to two different systems of thought and research. Praxeology no less than other branches of knowledge owes much to psychoanalysis. The more necessary is it then to become aware of the line which separates praxeology from psychoanalysis.

Action is not simply giving preference. Man also shows preference in situations in which things and events are unavoidable or are believed to be so. Thus a man may prefer sunshine to rain and may wish that the sun would dispel the clouds. He who only wishes and hopes does not interfere actively with the course of events and with the shaping of his own destiny. But acting man chooses, determines, and tries to reach an end. Of two things both of which he cannot have together he selects one and gives up the other. Action therefore always involves both taking and renunciation.

To express wishes and hopes and to announce planned action may be forms of action in so far as they aim in themselves at the realization of a certain purpose. But they must not be confused with the actions to which they refer. They are not identical with the actions they announce, recommend, or reject. Action is a real thing. What counts is a man’s total behavior, and not his talk about planned but not realized acts. On the other hand action must be clearly distinguished from the application of labor. Action means the employment of means for the attainment of ends. As a rule one of the means employed is the acting man’s labor. But this is not always the case. Under special conditions a word is all that is needed. He who gives orders or interdictions may act without any expenditure of labor. To talk or not to talk, to smile or to remain serious, may be action. To consume and to enjoy are no less action than to abstain from accessible consumption and enjoyment.

Praxeology consequently does not distinguish between “active” or energetic and “passive” or indolent man. The vigorous man industriously striving for the improvement of his condition acts neither more nor less than the lethargic man who sluggishly takes things as they come. For to do nothing and to be idle are also action, they too determine the course of events. Wherever the conditions for human interference are present, man acts no matter whether he interferes or refrains from interfering. He who endures what he could change acts no less than he who interferes in order to attain another result. A man who abstains from influencing the operation of physiological and instinctive factors which he could influence also acts. Action is not only doing but no less omitting to do what possibly could be done.

We may say that action is the manifestation of a man’s will. But this would not add anything to our knowledge. For the term will means nothing else than man’s faculty to choose between different states of affairs, to prefer one, to set aside the other, and to behave according to the decision made in aiming at the chosen state and forsaking the other.
