The Economic Point of View

7 Economics as a Science of Human Action

We must regard industrial and commercial life, not as a separate and detached region of activity, but as an organic part of our whole personal and social life; and we shall find the clue to the conduct of men in their commercial relations, not in the first instance amongst those characteristics wherein our pursuit of industrial objects differs from our pursuit of pleasure or of learning, or our efforts for some political and social ideal, but rather amongst those underlying principles of conduct and selection wherein they all resemble each other . . .

Philip H. Wicksteed

The whole subject matter of conduct . . . constitutes a different realm of reality from the external world . . .

The first fact to be recorded is that this realm of reality exists or “is there.” This fact cannot be proved or argued or “tested.” If anyone denies that men have interests or that “we” have a considerable amount of valid knowledge about them, economics and all its works will simply be to such a person what the world of color is to the blind man. But there would still be one difference: a man who is physically, ocularly blind may still be rated of normal intelligence and in his right mind.

Frank H. Knight

Thus far we have given an account of a number of different conceptions of economic science, each of which reflects a fundamentally distinct understanding of what is to be meant by the economic point of view. In the present chapter we bring our survey to a close with an exposition of yet another conception of the point of view taken by the economist. In its completest form this definition of economics, by virtue of which the discipline emerges as one of the group of sciences of human action, embraces an entire and unique epistemology of the branches of knowledge commonly subsumed under the cultural and social sciences. As such, the view of economics as a science of human action deserves a close and full discussion in its own right, together with a clear exposition of its points of contact, both of agreement and of conflict, with the views treated in previous chapters.

It is therefore the task of the present chapter to outline in some detail the conception of the nature of economic science as viewed from the perspective of praxeology. In addition, an attempt will be made to relate this view to several of the alternative definitions treated in earlier chapters. In particular, its points of contact with that discussed in the previous chapter will require careful examination. It will be shown that, side by side with the emergence of the view of economics as the science concerned with the allocation of scarce means, which culminated in the work of Professor Robbins, there has, for over sixty years, existed a stream of thought that has recognized the praxeological aspect of economics. The view of economics as concerned with scarce means will be seen to take its place naturally as an example of a limited application of praxeological ideas; many of its apparent inadequacies are seen to disappear when it is related explicitly to the broader concepts of a general theory of human action.

Coming at the end of a book setting forth a series of widely diverging views on the nature of the economic in human affairs, the subject of the present chapter throws a revealing light on the sources of this remarkable range of disagreement. The exposition of the praxeological element in social phenomena will help to explain why it so long succeeded in eluding the attention of so many brilliant thinkers. The recurrent and unfortunate identification of this economic aspect with so many of the actual facets of social history with which the praxeological element is intimately connected will gain in intelligibility, it is believed, by an understanding of the nature of social phenomena as viewed from the vantage point of praxeology itself.

The Sciences of Human Action

The description of economics as a praxeological science must necessarily be preceded by a rather detailed exposition of the praxeological point of view in general. This will readily be seen to embrace a far wider range of phenomena than is considered in conventional economics. At this point it is sufficient that the praxeological view sees economic affairs as distinguished solely by the fact that they belong to the larger body of phenomena that have their source in human actions. The core of the concept of human action is to be found in the unique property possessed by human beings of engaging in operations designed to attain a state of affairs that is preferred to that which has hitherto prevailed. A person perceives the possibility of an improvement in his position, perhaps through possession of an additional commodity, perhaps by the abandonment of an unwanted piece of property, by a change in physical location, or through some other alteration in the configuration of matters that might affect his sense of well-being. The recognition of any such opportunity for improving his well-being sets in motion the actions that the person will take to secure the improvement. The pattern of action taken will be broadly defined by the circumstances surrounding the desired alteration of affairs. Sound logic will, in a given situation, point to one or several courses of action that give promise of most successfully securing the desired change. In so far as human behavior is guided by logic, then, conduct will follow a path that has been selected by reason. This path of conduct is what is known praxeologically as human action.

The concrete forms that human action may take are as innumerable as are the ways in which men can achieve relief from states of relative dissatisfaction. The particular form that an individual human action takes is determined by factors that include those making up the specific environmental conditions as well as those that have shaped the character and values of the actor. The conception of sciences of human action recognizes that the form of action as it unfolds in its historical reality is the result of influences that range from the physiological to the religious, the social to the geographical. An explanation of human action can be adequately undertaken only with full awareness of these varied influences. The historian seeking to understand what men have done in particular instances must draw on the disciplines whose task it is to explain the sequences of cause and effect in the physical, physiological, or psychological influences upon action.

The contribution that the praxeological point of view has made to the scientific explication of action in history is the isolation of an element in action the explanation of which is not exhausted by even the most complete application of the sciences concerned with the concrete manifestations of human action. This residual element is that of the operation of human action itself, which neither is explained by physical, physiological, or psychological theories nor requires the assistance of these doctrines for its own exposition. A praxeological science, using the rationality of human action as its foundation, is able to derive theorems describing the path of action under given circumstances. The reasoning that constructs these theorems mirrors the reasoning that is implied in action itself. New links in the chain of knowledge, in the form of praxeological theorems, are forged from the constraint that human purposefulness imposes on action, namely, that it be taken only with the sanction of reason.

Given all the physical, physiological, and psychological influences on the setting of an action, action of a specific form might be predicted with assurance. But such prediction is conceivable, not because these influences in themselves determine action, but because action is subject to the mandate of reason, which guides the act into the path that is to be preferred among those indicated by these external influences. A complete knowledge on the part of an observer of these external influences might allow prediction of the form to be taken by action only because the logic of the observer enables him to know with certainty the path that the actor’s own logic will select. When a man is about to perform a mathematical computation upon given data, an observer of the data may attempt to predict the results that the computer will arrive at. But for such a prediction to be successful, it is not sufficient to rely on the fact that these results are “determined” by the data; it is necessary that the observer with his own logic be able to reproduce mentally the logical operations performed by the computer in arriving at his results. There is, of course, a definite meaning to the statement that the results of a mathematical computation are determined by the relevant data. An attempt at the computation by a human mathematician, however, yields these “determined” results only in so far as his logic constrains him to conform to the objectively correct computational operations. The case with human action in general is rather closely analogous to this example.

At the root of the notion of human action is the simple assumption that human reason plays a role in every action. Although, of course, by no means universally acceptable, this assumption remains a simple, and at least superficially, plausible one. No matter how compelling the physiological or physical factors that crave action may seem, it is within the power of reason to resist them. No matter how strong the psychological pressures on man may be, his actions have necessarily passed the scrutiny and gained at least the tacit assent of his reason. These pressures may well be overwhelmingly powerful, and, of course, in sanctioning or prohibiting action, men’s reason is operating with the consciousness of these imperious, often contradictory forces. The concept of human action depends, however, on the introspectively valid fact that there is a form of conduct that is specifically human, i.e., conduct that is accompanied by the consciousness of volition, of something more than a bundle of reflexes responding to specific stimuli. The nature of these various stimuli and the directions towards which they variously tend to guide action are completely independent of the desires and will of the actor. As such they are part of the subject matters of the physical, physiological, and psychological sciences. Were action taken simply in instinctive obedience to these stimuli, it could be conceived as objectively determined by the data constituting its setting, in the same way as the results of a mathematical computation are determined by the data of the problem. But because man possesses the power to reject one course of action for another, to arrange the satisfaction to be derived from obeying specific impulses within a wider ordering of values, the physical, physiological, and psychological sciences do not exhaust the facts of action that are capable of scientific explanation. The element in conduct that is the reflection of man’s power to weigh, arrange, and choose among courses of behavior is the specifically human element in action. The investigation of this element of human action and of its manifestation in various particular situations forms a field of study unique by virtue of the nature of human action itself. Sciences of human action will be distinct from other sciences in that the former begin where the latter end, viz., in the implications of the rationality that governs purposeful behavior.

The Emergence of the Praxeological View of Economics

Postponing for subsequent discussion the further details of the praxeological view and the consideration of the controversial points involved in it, we shall proceed to outline the development, during the past three quarters of a century, of the stream of thought to be regarded as the praxeological view of economic science. Since its emergence, the praxeological point of view has been most fruitful, not in the extensive exploration of new sciences of human action, but in the consequences of its recognizing the theorems of economics as being the propositions of a science of human action. The possibility of theoretical statements concerning economic activity was seen as not at all due to any supposed uniqueness in the phenomena of wealth or material welfare or money or any of the other numerous criteria that had been used in defining economics. It was perceived that economic theory derives from precisely that element in human behavior which we have described as human action. The particular forms of action that have been traditionally investigated by economists are, indeed, distinguished by close association with various institutions such as money or with specific patterns of action such as interpersonal exchange. But if there is any meaningful underlying unity in the theorems of economics, it is to be found only in the concept of human action. Seen from this vantage point, economic theory acquires immediately a position unique within the range of human knowledge. It is the discipline that has alone successfully sought to harness the element of human action to the scientific explanation of social phenomena.

Sherwood’s perception of the nature of human action and of the praxeological character of economics is unmistakably clear. The adjective “conscious,” which he constantly uses to describe the types of conduct dealt with by economics, and his explicit relation of such conduct to human motives identify the “master science” for which Sherwood is searching as an all-embracing praxeology. That Sherwood’s definition of economics represents, in this respect, an advance over that of his contemporaries becomes apparent from the originality of his attitude towards the use of the “economic principle” as the defining criterion. It was seen in an earlier chapter that several writers, such as Dietzel and Neumann in Germany and Hawley in the United States, had been deterred from using the economic principle as a criterion for defining economics on the very grounds that make the principal significant, namely, that it characterizes all kinds of human activity. These writers recognized the importance to economics of the rational element in economic activity; indeed, this element played so obvious and dominant a role in economic analysis that, as the “economic principle,” it suggested itself to them as the natural mark identifying the phenomena with which the discipline dealt. This suggestion they found themselves forced to reject on the ground that all human activity displays the very same hallmark of rationality, that the economic principle governs all the conscious activities of man. And this left them no choice but to seek for some other quality in economic phenomena that they, among all other social phenomena, might uniquely possess in common.

Sherwood, starting from a position substantially similar to that of these writers, was able to reach a quite different conclusion. Once it had been suggested that economic phenomena are susceptible of analysis by virtue of their rational quality, Sherwood found it impossible to discard this idea. Instead of being dismayed at finding a similar purposefulness, a similar rationality and adherence to the economic principle, throughout the range of human activities, Sherwood was awakened thereby to a new appreciation of the role of economics. Instead of impelling him to look for other characteristics by which to delineate the scope of economic science, the realization of the all-pervasive influence of the economic principle convinced Sherwood of the futility and artificiality of erecting rigid boundaries purporting to separate economic activity from human action generally. The conscious direction of resources to the end of gaining conscious satisfaction was so fundamental to the very conception of economics and was at the same time so obviously a factor decisive in all action, that Sherwood could see economics transformed into a spearhead of a new “master science” that might investigate the consequences in activity generally of the consciously motivated element in action. Hitherto economics had been confined, to be sure, to specific kinds of phenomena, but this restriction was an artificial one and in no way corresponded to a unique field of knowledge.

This statement of the nature of economics seems to have passed unnoticed in the literature. Happily, similar ideas were being formulated at about the very same time by the celebrated Italian philosopher, Benedetto Croce. His views were set down with rather greater painstaking precision and expounded against the background of a fully articulated general philosophical and epistemological system. As such, Croce’s position has attracted the attention of a number of subsequent writers. It has not always been appreciated, however, how closely Croce’s view of economics mirrors the praxeological outlook. This feature of Croce’s ideas on the nature of economy and economics is brought clearly into focus by their juxtaposition with the radically different views of Pareto, with whom Croce conducted an elaborate exchange of opinions on the subject. A brief review of Croce’s opinions as expressed in this published correspondence will at the same time provide a remarkably clear, if not complete, statement of the view of economics as a science of human action.

Croce’s ideas will have been perhaps more fully set forth when we shall have considered his contributions to several points of detail in the praxeological conception of economics. Although his stature as a thinker drew more academic attention to these ideas than had been given to those of Sherwood, Croce’s impact on the development of economic methodology has to this day not reached its full potential. Writings during the last half century on the proper conception of economic science could in many instances have greatly benefited from familiarity with Croce’s work in this field. One author whose writings do deserve a place in any discussion of the evolution of praxeological ideas, although his contribution in this respect scarcely approaches that of Croce, is Max Weber.

Max Weber and Human Action

The great sociologist’s views on the nature of economics and, in particular, the significance of his ideas for the development of praxeology are closely related to his views on the social sciences in general. These in turn revolve around the concept of Verstehen, which is the epistemological tool that Weber used to distinguish the Geisteswissenschaften from the natural sciences. It is of some interest to compare Weber’s way of achieving this distinction with the method used by Croce.

Weber, indeed, is able to extend the concept of Verstehen to grasp the behavior of the most unreasonable or emotional human beings. To approach the construction of an economic science, it is necessary first for Weber to introduce the notion of the “ideal type,” i.e., the formulation of abstract, arbitrary models of acting man. Only one of Weber’s four ideal types finds a place in his concept of economics. This is the ideal type of rational action, the model of a coldly calculating human being conscious of ends and means. Within the range of actions that can be intuitively grasped because of their motivations there exist patterns of action that are distinguished in that they are in fact suited to the attainment of the chosen goals. Among these patterns are to be found the materials to be studied by the economist as Weber conceives him.

Acting Man and Economizing Man: Mises and Robbins

In the decades following the age of Weber, praxeological ideas developed in two directions, yielding two related, but significantly distinct, conceptions of economic science. On the one hand, there developed, partly under the influence of Max Weber, the conception of economics that has been treated in the previous chapter. Here the ends-means dichotomy came to serve as the framework for the construction of an economic science that took as its foundation the idea of economizing. The previous chapter has described the culmination of this stream of thought in the work of Professor Robbins. This must now be clearly related to another direction of praxeological thought, to the influence of which, indeed, the development of the first must in some degree be ascribed.

Economizing consists in the allocation of scarce resources among competing ends. Acting, in the praxeological sense, consists in selecting a pattern of behavior designed to further the actor’s purposes. Of course, the particular allocation that, in any given situation, will be made of scarce means in respect of different ends will constitute a course of action, a pattern of conduct designed to further the achievement of as many of those goals (in their preferred order) as possible. But the concept of action is wider and at the same time more fundamental than that of economizing. Although action may be described in terms of ends and means, such a description is quite different from that of an operation of economizing. In the concept of economy, ends and means constitute a scheme more or less artificially imposed on action so that the relative valuations of ends can be reflected in the specific pattern in which resources are allocated. The essential idea becomes, not the intent pursuit of a set purpose, but the almost mechanical translation of the scale of “ultimate” ends into appropriately apportioned shares at the level of means. “Means” are required for the notion of economy because they are the entities that must be “allocated”; it is in the comparison of different ways of utilizing resources that economizing finds its place.

With the broader notion of action, on the other hand, we are not primarily interested in the particular pattern in which resources will be apportioned among ends. Such an allocation, if carried out, will be of interest as one of the possible implications of action and will, of course, as such, find a place somewhere in the science of human action. But on the basis of Robbins’ conception of the nature of economic science, economics can achieve homogeneity and individuality only by virtue of its concern with the existence of such operations of comparison and allocation of means. The praxeological approach, on the other hand, finds a basis for the homogeneity and individuality of economics at a deeper level, which does not necessarily require a clearly recognizable pattern of allocation. This basis is found in the fundamental characteristic of action, viz., that it is conduct directed at the achievement of a purpose.

In this characteristic, praxeology finds a sufficient source of explanation for the specific patterns of action, among which the judicious disposal of scarce means appears as a frequent example. But a really unique criterion for the definition of economics is not to be found in the idea of allocating scarce resources, nor can this concept serve as an adequate foundation on which that science can be constructed. The key point is not that acting man ponders the comparative efficacy in different uses of certain given “means,” but that he behaves under a constraint that he himself has imposed, i.e., the necessity of acting in order to achieve what he wants to achieve, so that his behavior tends to conform to the pattern implied by his scale of ends. “Means” exist as such for acting man only after he has turned them to his purpose; acting is not apportioning, but doing—doing what seems likely to further one’s purposes.

The remainder of this chapter, which attempts to set forth several details of the praxeological view and to consider various criticisms levelled against it, will serve at the same time as a commentary on the similarities and distinctions between an economics built around homo agens and one centered around economizing man.

II

Praxeology and Purpose

We shall begin the more detailed dissection of the category of human action and the discussion of its suitability to serve as the focus of the economic point of view with a survey of the role of purpose in action. It has already been noticed in this chapter that it is purpose that endows the behavior of men with the unique properties that praxeology finds in human action. The views of Croce and Weber have been cited in this connection as expressions of the discovery, in the act, of a phenomenon unlike anything coming within the range of observation of the physical sciences. Stones dislodged from a hillside by the elements and hurtling down on the unsuspecting traveller in the valley are part of a different “event” than stones hurled with intent by men waiting in ambush. The latter are hurled with purpose; they are—in this case literally—aimed by human beings. Stone-throwing by human beings is something that the scientist can in part “explain” by reference to an element not present in natural phenomena, viz., the conscious aim of the thrower. Praxeology takes this very element as its point of departure; it finds human actions amenable to analysis in that they bear the imprint of a constraint imposed by chosen goals.

Now, the recognition of purposefulness in economic activity did not begin with the emergence of praxeological ideas. It is, of course, true that the older conceptions of economic science, which saw it as concerned with an objective entity such as wealth or goods, did not require reference to the purposefulness of human action. The scope of their discipline was described completely by the character of the objects whose “laws” it investigated. But even here it was difficult to avoid the implication of purposefulness in men’s attitude towards these objects. This implication was given tacit recognition in the substantive analysis that the classical economists employed, and it tended to be brought into the open in the more sophisticated of the classical attempts to define “wealth.”

Emphasis of this kind is called for, perhaps, in order to disassociate the praxeological approach from what may be called the “positivist” conception of rationality in human action. It was seen in the previous chapter that Professor Robbins has been charged with employing the ends-means dichotomy in too positivistic a fashion. An “end” in Robbins’ scheme, it has been alleged, is set up by an external observer as something positive, as a “correlate of a tendency to conduct”; it is used by Robbins in a way that abstracts from the conscious aiming and striving that characterizes human actions before they have been completed. “Rationality” in the disposition of means with regard to such denatured ends becomes simply the mechanical ordering and sharing of resources according to a given pattern.

Without our entering here into a discussion concerning the justice of this objection to Robbins’ system, it is worthwhile to make explicit the quite different kind of rationality that is central to the praxeological view. Action is not described as rational because it involves the automatic manipulation of resources into a pattern faithfully reflecting a given hierarchy of ends. Rationality consists rather in the transference, to conduct involving means, of those features in behavior that accompany the direct pursuit of ends. Rationality involves the conscious effort to make one’s conduct conform to a given path; it calls for the same aiming and striving by the economic agent towards necessary intermediate goals as he displays towards the “final” goals themselves. It is only from the “outside” that such rationality can be described merely in terms of a particular pattern of resource allocation. The full praxeological grasp of human action perceives its rationality as completely pervaded by the “aiming” quality bestowed on action by its teleological character. This aspect of purpose leads, in fact, directly into the more detailed exposition of the praxeological view of rationality, which is the subject of the succeeding section.

Praxeology and Rationality

The concept of rationality in human behavior has long been a topic for discussion in the literature on the methodology of economics. Attacks on the undue reliance which economic theory has been accused of placing upon human reason are as old as attacks on the very notion of an economic theory. Historically-minded critics of theory long ago discovered that man is possessed of “instincts,” that he is a creature of “habit,” that he is capable of being carried away by mass hysteria and other psychological aberrations. Economic theory, it was found, had blindly ignored the realities of life. Where it had not explicitly endowed economic man with an exclusive thirst for “wealth” or with an utterly selfish character, economics had apparently proceeded on the quite gratuitous assumption that men behave sensibly from the point of view of their own interests. It was easy to demonstrate how far from the truth economics must be; it was easy to point out the true character of men with their full array of impulses, instincts, and stupidities. On the other hand, it was not difficult for economists to defend their theorems as hypothetical constructions with a definite, if limited, applicability to the real world, or, alternatively, as providing norms for the appraisal of actual performance. And debates on these lines abound in the economic journals of the decades around the turn of the century and later.

In all these discussions the assumption of rationality made by traditional economic theory was treated in a special sense; and what is chiefly responsible for the misunderstandings mentioned above is the confusion of this traditional conception of rationality with the conception of it employed in praxeological discussions. The point at issue in the earlier discussions concerning the empirical validity of economic theorems that treat men as reasoning beings free of irrational impulses and instincts was the fruitfulness of a particular simplifying abstraction. The social phenomena of the real world are the consequences of human actions in which all types of influences have played a part. One of these influences stems from man’s reasoning powers, which urge him to pursue a selected goal with a steadfastness and tenacity unperturbed by human weaknesses and passions. Economic theory, it was believed, investigates social phenomena on the assumption that this influence of cool reason is, in fact, sufficiently powerful to make man pursue unwaveringly a goal once chosen. And this assumption, introduced in order to make analysis possible, was criticized or defended in respect to its justifiability, in the light of the realities of human nature.

It was quite natural for the conception of rationality that was made central to praxeological ideas to be discussed in a similar fashion. When these ideas are made to hinge on a conception of rationality as a pervasive quality of all human action, they of course invited criticism as being in contradiction to the facts. And when it is pointed out that in the sense in which the praxeological view sees human actions as rational, no such contradiction exists, then the praxeological postulate of rationality is criticized as a misleading and empty use of words. It is explained, for example, that a man who is swayed from the pursuit of his own best interests by falling prey to a fleeting temptation is yet acting “rationally” in the praxeological sense. In the praxeological view, the man has simply substituted a new set of ends, represented by the fleeting temptation, for the previously chosen ends. The fact that in the eyes of an outside observer, or even in the eyes of the man himself at a cooler moment, it is the original set of ends that constitutes the man’s “best interests,” is not sufficient to justify our labeling the man’s pursuit of his newly selected goal as “irrational.” The selection of an end can never, as such, be judged in regard to its rationality; and there is no reason to question the rationality with which the man pursues his newly chosen end.

It is this kind of explanation that provokes the annoyance of the critics and incurs the charge of using the word “rational” in a viciously misleading manner. These strictures are, in fact, quite undeserved; and it is worthwhile to devote attention to clearing up the confusion on this point. We can perhaps best succeed in this by considering in some detail the contribution of Tagliacozzo, mentioned in the previous chapter, to the clarification of the notion of “economic error” or “uneconomic behavior.” Tagliacozzo deals with the “Rhine-wine” situation which had been involved in the Pareto-Croce correspondence cited earlier in this chapter at the turn of the century.

It was with this example of an economic error, the consumption of wine in defiance of a previously chosen program, that Tagliacozzo dealt at length. Tagliacozzo pointed out that the purchase of wine can be appraised from various vantage points. From the standpoint of full reality, no distinction between means and ends need be made at all. Wine has been purchased because such a purchase was desired, and that is all. There is no recognition of any “program” against which the man’s action is to be compared and in terms of which it can incur disapproval or excite remorse. There is, consequently, no notion of an “end” separate from the means that might “bring about” the realization of the end.

From the point of view of the man’s own budget plan, however, the case is very different. Here a yardstick has been set up by the man himself against which the “economic” correctness of his actions can be measured and found wanting. The artificial creation of a “plan” in the form of a prior selection of ends necessarily carries with it a “point of view” from which it is possible to appraise the wine purchase and to convict it of economic error.

Finally, the man’s action can be contemplated with the realization that any one yardstick in the form of a program will necessarily be quite arbitrary; that the span of time over which such a “program” is to have validity may be as long or as short as we please. From this point of view it is clear that what is a “temptation” from the standpoint of a long-range program becomes itself an independent “program” in its own right in relation to a suitably brief span of time taken as a frame of reference. The consumption of wine has now become the desired end; the man’s actions can still be appraised, but only for their consistency with this newly adopted “program.”

The Assumption of Constant Wants—the Praxeological Context

Closely related to the preceding definition of the sense in which praxeology depends on the rationality of human action is the further clarification of the relevance of such rationality for a praxeological science, and especially of the character of the assumption of a constancy of wants. A praxeological theorem becomes possible because of the quality of purpose in action. This quality enables the praxeological theorist, by resorting to his own reason, to predict the path that a given person will follow under the requirement of using his reason in order to fulfil his purposes.

The appreciation of the character of a praxeological theorem so derived throws immediate light on the notion of “given ends” and the assumption of a constancy of wants, both of which are inevitably involved in such a theorem. The previous chapter dealt in some detail with Robbins’ conception of ends as data for economics. It will be noticed that the praxeological view places equal emphasis, and for substantially similar reasons, on the notion of given wants and purposes. The point at issue hinges on the very possibility of knowledge acquired through praxeological excogitation.

A great city is served by alternative means of transportation; one of these means of transportation has been crippled by an accident. It will be obvious to the observer of the effects of the accident that the alternative means of transportation will tend to be employed in larger than normal volume. In making this prediction the observer has made a simple application of his reasoning powers to a problem of human action; he has applied a theorem of praxeology. The knowledge that he has so acquired is a piece of information different from the data from which he began, but which was, nevertheless, implied in the assumptions concerning human purposes that the observer felt entitled to make. Because he was able to assume that many people desired transportation with sufficient urgency, the observer was able, from his own knowledge of the alternatives open to them, to predict the course of action that they would take. It is clear that this newly acquired knowledge was gained only because of the existence of given purposes, and it is only in relation to these given purposes that this praxeological knowledge has significance.

Analysis of human action can proceed only by the treatment of given purposes as data; the effects of a change in surrounding circumstances can be deduced only on the assumption that these purposes are adhered to with constancy, that no new “program” has been substituted for the old. These restrictions on the derivation of praxeological knowledge follow from what has been said in the previous section concerning the rationality implicit in the concept of human action. It was seen that the rationality of action can be appraised relatively to various mutually inconsistent programs that a person may, under different sets of conditions, have chosen. Because this is the case, it is essential, for the derivation of a praxeological theorem, that it be formulated in reference to one such program, whose dominance and relevance must, along with other information, be supplied by the data. Once the data have been supplied, theorems may be derived that will possess necessary truth, but their validity remains strictly dependent on the data; their truth is limited to the “programs” to which they are relevant.

It is a curious fact that critics of economic theory have time and again seized on this feature as a central and damning weakness. The application of economic theorems to the explanation of concrete historical situations requires careful scrutiny of the data on which such theorems are to be grounded. The data will vary, of course, from one concrete case to another. The correct use of economic propositions in particular real situations presupposes, as a matter of course, adequate factual information regarding changes in the data. The writers who have from time to time disparaged the work of economic theorists altogether and urged economists to devote themselves more or less exclusively to the description and classification of those changing facts themselves have pointed to the “relativity” of theories. They considered the necessary limitations on theoretical constructions, which are imposed by virtue of the fact that they are valid only in relation to given programs, as grounds for believing that economic knowledge can be derived more efficiently by simple reference to the changing programs themselves. An economic theory might be an elegant source of intellectual satisfaction, but the severe circumscription of its applicability made it of only academic interest.

It seems worthwhile to point out that, as our discussion of the foundations of praxeological knowledge makes clear, the acknowledged relativity of a praxeological theorem to a given program as its frame of reference is, in fact, not a weakness at all, but is, on the contrary, a reflection of remarkable scientific achievement. Contemplation of the raw data alone presents a range of social phenomena that seem to defy orderly explanation altogether. It seems impossible to develop chains of cause and effect that can bring any semblance of determinacy into the data. Certainly mere analysis of the masses of empirical figures cannot yield any stable “laws” and relationships. The very fact of changing programs, changing tastes and prejudices, makes for an area in which no logical necessity is visible at all and in which everything seems to be in a condition of haphazard flux.

It is into this bewildering mass of empirical data that the economic point of view throws a ray of light. It enables us to grasp an element that does introduce a measure of explanation into social phenomena. This element is laid bare by subjecting the empirical data to a systematic abstraction, made possible by recognition of the character of human action. By taking a cross section of social phenomena at a particular instant in time, by considering the programs that members of society have chosen at that instant and by mentally arresting program changes, one can apply praxeological theorems to these various programs and deduce the consequences. The conclusions so derived are valid in relation to the assumed programs, and provide an explanation of the concrete phenomena of the real world in so far as there is a tendency for men to adhere to programs once they have been initiated. Moreover, once the possibility of this type of explanation is grasped, it is clear that all historical phenomena admit, at least in principle, of being treated in such terms. It becomes merely a matter of feeding the suitable assumptions and data into the theoretical system and extracting the appropriately complicated chains of reasoning.

The crucial point is that the perception of any kind of explanatory framework has been made possible only by prescinding from any conceivable change in a given set of programs. The introduction of any kind of order into the jungle of empirical data has been accomplished by abstracting from full reality and accepting a hypothetical state of affairs as a frame of reference. It is the outstanding achievement of economic theorists to have been able to recognize determinate causal chains within the tangles of statistics; they were able to succeed in this only by treating social phenomena as the systematic working out of the praxeological consequences of given programs that were adhered to. A particular program may not necessarily be adhered to, but the emergence of human action at all presupposes the existence of some program that was adhered to, and it is in reference to this that praxeological reasoning provides the explanatory key.

Here again various levels of discussion are possible. Unquestionably the most “interesting” and, for the business of living, the most important is the consideration of the ways in which men have acquired their particular interests; the development of particular programs that men believe worthy of undertaking; the forces that determine people’s value judgments and the emergence of their sense of absolute moral appraisement. The level of interpretation on which praxeology has a contribution to make is, however, a more modest one. It is willing to accept the interests and programs of men as data and seeks to understand, in terms of these interests and programs, the chains of consequences that can be deduced. The principles of human action make it possible to ascribe and refer back historical events to such interests and programs as “final causes” that can be accepted without further explanation.

Praxeology, Apriorism, and Operationalism

Professor Mises in particular has stressed the a priori nature of praxeological knowledge. A theorem of a praxeological science provides information that has been derived by sheer reasoning; it is the product of pure logic without the assistance of any empirical observation. As such, a praxeological theorem is congeneric with a theorem of geometry; being the rigorously derived consequences of given assumptions, it partakes of the “apodictic certainty” that is necessarily possessed by such an exercise in logic.

The separation that is thus emphasized, between the facts and their logical analysis through economic reasoning, is a fruitful one. It stresses the quite distinct operations that are being performed in the observation of economic history and in the development of economic theorems. It focuses attention on the new source of knowledge that is provided by our understanding the nature of action. It illuminates the striking fact that pure reason can convey knowledge concerning brute facts of the real world. Because men act as reasoning beings, it is possible to explain their concrete patterns of behavior by applying to their attitude the theorems that our own reason has supplied.

All this does not prevent the praxeologist from maintaining a becoming modesty with regard to his own contribution. He does not in any way believe that his theorems can exhaust all that can be known about social phenomena; he does insist on the unique assistance he can provide. He does not deplore close attention to market data, to masses of statistics, and the like; but he does deprecate the view that this kind of scrutiny can be a substitute for economic reasoning or that it needs to be resorted to as a “test” for the correctness of such reasoning. His recognition of the category of human action does impress upon him most forcefully the utter helplessness with which the masses of facts must be faced without the illumination provided by a procedure of analysis that itself owes nothing to these facts—the application of economic reasoning.

The Economic Point of View and Praxeology

Our discussion thus far in this chapter has made no attempt to distinguish a specifically economic point of view from the general praxeological outlook. We set out, in this book, to examine the various points of view held to characterize economic science and through which an “economic” aspect of social phenomena has been distinguished. Our search has led us in this chapter to consider the filiation of ideas that have found the specifically economic point of view to be merely part of a broader perspective, the praxeological view. The economic aspect of affairs is simply the praxeological; a theorem of economics is simply a praxeological proposition.

To be sure, the praxeological perspective embraces a range of human action far wider than that usually treated in economic theory. All human actions, motivated though they may be by the entire range of the purposes that have inspired and fired men to act, come within the sway of the ideal praxeological discipline. The constraint that men feel to fulfil their purposes in spite of obstacles pervades all aspects of life. It is the position of praxeology that the common category that embraces the entire range of human efforts is the key to economic science. We have seen at various points in this book that economists have again and again searched for something in economics that should differentiate it from the rest of human action. These thinkers were deterred from expounding the praxeological character of economics for the very reason that this character is common to other aspects of social life.

Economic theory has traditionally dealt with the phenomena of the market, prices, production, and monetary calculation. In these spheres of human activity, theorists have developed constructions that help to explain the regularities these phenomena evince and to bring into clear focus the tendencies for change in these phenomena consequent upon given autonomous changes in the data. Writers on economics have striven to present precise definitions of the scope of this discipline. From the point of view of praxeology, the earlier attempts suffered from their tendency to seek for the defining criteria in the nature of the specific affairs with which market phenomena are concerned. The consequence of these searches was the series of formulations examined in the earlier chapters of this book. The subject matter of economics came to be connected with the material things that are the objects of traffic in the market; it came to be linked peculiarly with the use of money in market transactions or with the specific social relationships that characterize the market system. Where writers came closest to the recognition that these criteria were only accidental characteristics of the affairs upon which economic analysis could be brought to bear, where they were able to glimpse the congenerousness of the specifically economic type of analysis with the underlying actions of men, they were unable to follow this clue to the conclusion to which it pointed. Precisely because those features in action that made it susceptible of economic analysis seemed common to all human activities, these writers were driven back to look for some other defining characteristic. And this meant again the search for some arbitrary quality to justify selecting the particular slice of pie that made up economic theory; but it meant in addition the relegation yet further into the background of the true recipe of that larger pie from which their conception of economics was being arbitrarily hacked.

From this point of view the formulation of the nature of the economic in terms of the allocation of scarce means among competing ends occupies a rather special position. This definition, discussed at length in the previous chapter, differs from the rest in its approach to the problem. It defines an aspect of human activities in general; it does not look for the key to economic phenomena in the specific kinds of activity with which they are mostly concerned. In finding the economic aspect of activities in general to consist in concern with the ends-means relationship, this conception too includes within its scope kinds of actions with which economics has had traditionally little to do. From the praxeological standpoint, in fact, the idea of economizing scarce means in allocating them among alternative ends, when used as a criterion for defining the domain of the economic, is nothing but a convenient, though artificial, framework in which human actions can be analyzed. The allocation among competing goals is a technical concomitant of a good deal of purposeful behavior. Human action does frequently call for carefully apportioning scarce means among competing projects. In a formal sense it is even possible to consider all human action as consisting in such allocation; but this involves the kind of artificiality in the conception of ends and means with which Professor Robbins’ definition was charged. The principal merit of the latter is thus its implicit dependence on the concept of human action; its apparent inadequacies stem from its attempt to consider action as conforming to a particular technical pattern. Much of the criticism Robbins’ definition received will be seen to dissolve when his conception of economics is related more clearly to the idea of human action. The allocation of scarce means among alternative ends simply signifies the consistent pursuit of ends, the consistent pursuit of the more highly valued ends taking precedence over the fulfilment of the less highly esteemed ends. It means, in fact, the exercise of the human faculty for purposeful action.

It can be explained, that is, that the controversy has an economic aspect because the assumed copyright laws affect the conditions of human action in either or both of two ways. In the first place, as they render the use of the plays scarce, the laws will have altered the pattern of action on the part of prospective producers. An additional obstacle has been placed in the way of persons desiring to produce the plays; and it will be obvious that a prospective producer will be constrained to forgo some less highly prized gratification in order to fulfil his dramatic purposes. On the other hand, it will be clear that this state of affairs opens up a new avenue by which the legal owner of the plays may possibly be enabled to fulfil his own purposes more completely, through taking advantage of the producers’ attitudes. Either of these two influences of the controversy on human actions is sufficient to invest it with interest for the economic point of view. This way of expressing the nature of this point of view, however, reveals at the same time the very nature of the analysis that it makes possible.
