The human sciences aim to explain the causes of human motivation and behavior, healthy and effective, as well as harmful, and to guide humans in their choices and action to achieve chosen goals. This includes all applied human sciences whose aims are to get things done and done well. Economics is not just a highly deductive science, but also highly applied in that its aim is to define the principles of cooperation under a division of labor that will secure peace and prosperity in a social setting.*
Let us now continue with a few additional epistemological issues in Mises’ writing.
4. The specific understanding. The two fundamental methods of cognition, according to Mises and the Kantian philosophers, are conception and understanding. Concepts, we have seen from part one of this series, according to Kant, are limited to the phenomenal world, which means we cannot know concretes. This poses a problem in particular for historians, since their work is to explain concrete human events of the past. The solution in German philosophy is the specific understanding (Human Action, 49-50). Mises writes:
It is the method which all historians and all other people always apply in commenting upon human events of the past and in forecasting future events….The scope of understanding is the mental grasp of phenomena which cannot be totally elucidated by logic, mathematics, praxeology, and the natural sciences.The philosopher Bergson, according to Mises, called this cognitive power “intuition,” which sounds antithetical to reason and mystical. And it is, because for Kant concepts and reason, which he had to limit to make room for faith, cannot know true reality.
But a correct theory of concepts proves we can know reality. This cognitive power is not properly described as a “specific understanding,” but as the application of previously formed universal concepts, a deductive process. Since our concepts refer to all concretes of a particular type, we live our daily lives applying our previously learned knowledge to identify correctly the specifics we confront. Thus, Sherlock Holmes deduced that Watson just came back from Afghanistan, based on Watson’s tan and signs of having been wounded. And our medical doctor deduces that our cough and runny nose are instances—symptoms—of a cold.
Application (1, 2) is the mental process of identifying a this (concrete) as an instance of a that (concept). It is what historians do and what we all do every day.
5. Regularity in human action, but no constants. Mises (Human Action, 1) is correct to state that there is “a regularity in the sequence and interdependence of market phenomena,” but no “constant relations” (56), or standard unit that can be used to make quantitatively exact measurements of human behavior. Which means no algebraic equations can be identified or used as in physics and chemistry.
Human behavior is not deterministic because of free will, which Mises does not explicitly endorse, though he does say that human action is teleological, which is another instance of his Aristotelianism. But because of the observed regularity that is present in human nature, principles and laws of economics, such as the laws of marginal utility and supply and demand, can be formulated and used to interpret current and past economic events and to make predictions, albeit not mathematically precise predictions. This is Mises’ rejection of the positivist demands for a mathematical economics.** (See In Defense of Advertising, 127-30.)
Indeed, the inability to formulate mathematically precise propositions and equations is true of all human sciences, basic and applied, not to mention of all the branches of philosophy. Positivism has corrupted our understanding of science, the actual essence of which is conceptualization, which means measurement omission even in the formulation of the equations of physical science. (See In Defense of Advertising, 153-58; Independent Judgment and Introspection, 72-81.) Most measurements, especially statistics, produce historical data, not universal knowledge of cause-effect relationships.
6. Subjective value. I touched on this subject in a previous post based on what I call Ayn Rand’s general theory of value, but more needs to be said.
Mises (Human Action, 96) is mostly correct when he states, “Value is not intrinsic, it is not in things. It is within us; it is the way in which man reacts to the conditions of his environment.” Values, and all concepts are within us. Essences and values are not “out there” in the thing. They are not metaphysical. We, using the tools, or mental processes of our consciousness, create, construct, or form concepts, including the concept of what is valuable. But values are objective in the epistemological sense—if the identification of what is valuable contributes to the flourishing of human life.
Yes, there is a distinction between object and subject, meaning objects are “out there” and whatever goes on in our minds is subjective, but that is a different usage. Customer value judgments are subjective because their judgments come from inside their heads, but they may or may not be epistemologically objective (correctly identified as beneficial for or harmful to them).
Mises—and the positivists—talk about the necessity of all sciences being “value-free,” which means “shoulds” and “oughts” do not belong in science. This derives from Kant who faced a dilemma between ethical values that come from the nature of the mind (not the requirements of human life) and free will that comes from the noumenal world, but is unknowable. Positivists “resolved” the dilemma by explicitly making all values subjective.
Economics for the most part is a practical science, establishing principles of how to increase wealth for everyone. One can say that price controls are both immoral and impractical—immoral because of the harm to human life caused by injecting force into voluntary trading and the consequent shortages that result, thus introducing values into the discussion, and impractical because wealth for everyone is decreased, not increased. It is only increased, if in fact it is, for certain privileged groups.
Yes, there are those today who say that all issues are moral and political, proclaiming “consumers should or ought not to buy that product” or “that bridge should not be built in that location.” In a free society where individual rights, especially property rights, are respected, such shoulds and oughts would be minimal. Applied sciences assume that actions to be taken are moral and legal, then provide guidance to the achievement of particular goals. The actions are assumed to be moral and legal because the aim of applied science, all sciences actually, is to improve life.
Two final quotations from Mises about values: “By means of its subjectivism, the modern theory becomes objective science” (Epistemological Problems of Economics, 192). And: “it is in this subjectivism that the objectivity of our science lies” (Human Action, 21).
Mises is stating that the theory of marginal utility answered the water-diamond paradox of the classical economists who had assumed values are “out there” intrinsic to reality. If “subjective” is understood as explained above and can be viewed as epistemologically objective, then Mises is correct.
I prefer to call our values, market values in particular, “psychological,” which makes them epistemological, not metaphysical. Restating Mises’ second quotation, I would say, “it is in this recognition that values are psychological, not intrinsic or metaphysical, that the validation of economics lies.” (See In Defense of Advertising, 175-78.)***
In the first paragraph of the Preface to the Ultimate Foundation of Economic Science, Mises writes, “This essay is not a contribution to philosophy. It is merely the exposition of certain ideas that attempts to deal with the theory of knowledge ought to take into full account.” Mises in dealing with these issues is taking steps toward a post-Kantian Aristotelian foundation of economics. Those who would advance economics further can build on his work.
The present three-part series has been my attempt to deal with some of the issues, based on Ayn Rand’s epistemology. It is also my encouragement to students of Ayn Rand to take the work of Mises as both profound and serious. There is much to be learned from him.
* All sciences, basic and applied, use induction and deduction throughout (cf. Aristotle, Posterior Analytics, in McKeon). The applied sciences—medicine, engineering, psychotherapy, and the business disciplines, among others—are predominantly deductive, drawing their basic principles from the more fundamental sciences.
** In technical terms, the physical sciences measure the world using interval and ratio scales, the former using equal intervals from one number to the next (1 to 2 is equal to 4 to 5) and the latter requiring equal intervals and a true zero point to produce valid ratios (for example, Kelvin temperature, but not Fahrenheit or Celsius, which are scaled at the interval level). In the human sciences, measurement is teleological using ordinal numbers and ordinal scales (A is better than or preferred to B and B to C). Relationships of means to ends are graded or ranked because we do not have a unit that serves as a standard of measure in the way interval and ratio scales do. The intensity of preference in the intervals of two people preferring A to B may or may not be equal; we do not know. See Stevens and cf. Ayn Rand, Introduction to Objectivist Epistemology, 32-34, 223-25.
*** Ayn Rand in Capitalism: The Unknown Ideal (16-17) distinguishes between market value, or price, as socially objective value, “the sum of the individual judgments of all the men involved in trade at a given time” and philosophically objective value, “as value estimated from the standpoint of the best possible to man.” Understanding this last means philosophically objective values are not much involved in economics, as no such value should or ought to be mandated by law, or priced a certain way.
