Mises and Kant (part two of a three-part series) (Go to part one)(part three)

Aristotle’s categories, detailed in his work called The Categories, are fundamental concepts of reality, such as entity, quality, action, etc.
 
Immanuel Kant, using some of those terms, describes categories as fundamental, innate concepts that prevent us from knowing true, noumenal reality. We can only know appearances, says Kant, called the phenomenal world. This creates the impossibility of perceiving “things-in-themselves,” which means concept formation is limited and cannot know concretes (Rickert 1; 2, chap. 5).
 
This is what makes reason impotent to know reality and in essence is Kant’s disastrous influence on later philosophy. It has confounded nearly all who have followed him, including economists such as Ludwig von Mises.
 
But let us go back to birth—of an infant. Perception, which is to say, knowledge of concretes, begins at birth. The infant cries when hungry and cries when having to eliminate. We know this because infants, after a short time out of the womb, will give us a cute smile when sated and when vacated. This is one of our (the infant’s) first perceptions of concretes.
 
Awareness of the concretes of reality is not, or rather should not be, a philosophical problem. We live and act in the world of concretes, which in fact are the so-called things in themselves. A theory of concept formation that incorporates concretes is what has been needed for hundreds of years. Ayn Rand, I submit, has provided this solution and the answer to the philosophical problem of universals (Introduction to Objectivist Epistemology).
 
A child at around one or two, after learning some elementary words, begins to form and apply universal concepts, such as “ball,” “dog,” and “table.”
 
In briefest essence, the child, according to Rand’s theory of concept formation, observes differences and similarities in the world and focuses on the similarities of what we eventually call a ball, dog, or table. Similarities of, say, tables are abstracted from the concretes by omitting their measurable differences, then by integrating the similarities into a new mental entity called a concept. The mind is “so constituted as to be capable of this process,” to borrow a few words from Aristotle (Posterior Analytics, 100a13), which means the child does not have to think about that particular process for it to happen.
 
The concept, using Rand’s metaphor, is like a file folder that includes all concrete, specific tables past, present, or future, observed or not. The (mental) omission of measurements gives us the essential distinguishing characteristic and the nature of the concept as universal. A word labels it and its definition summarizes its meaning, tying it to the general category from which it was differentiated, and to all of those observed and unobserved concretes, its referents “out there” in reality.
 
This is the inductive process of concept formation. Application is the deductive process of recognizing an object initially unfamiliar to us and identifying it as an instance, a concrete, of the concept table.
 
Now let us see what we can say about some of Mises’ confusions caused by German, especially Kantian, philosophy.
 
 
1. A priori categories and the logical structure of the human mind (Human Action, chap. 1 & 2). If by “logical structure of the human mind,” Mises means that consciousness has an active nature, or identity, then he is correct, but Mises says that such categories as causality and human action are innate, prior to experience like, allegedly, mathematics and logic. Therefore, deduction is the fundamental method of praxeology (human science).
 
The a priori/a posteriori distinction, however, is a false dichotomy. All cognition is cognition of reality. If our concepts are true—correctly recognizing or identifying reality—then the most abstract concepts, such as the law of non-contradiction, integral calculus, causality, human action, and the law of supply and demand, are all derived from reality and therefore are empirical. The chain of abstractions required to arrive at these concepts may be extensive, but if true, will be anchored in the perceptual world. In the same way that “human-made object” is anchored in the perceptual world, derived initially from “tables,” “chairs,” and “beds,” and connected to the abstraction from abstraction “furniture,” and still further connected to the broader abstraction of the human made, all the different categories and subcategories of objects that humans create. This last notion of a broader concept becomes a big file folder holding all human-made objects.
 
Mises does not seem to have a notion of abstractions from abstractions, only directly perceivable concretes (an apparent influence from positivism) and the innate categories from which all of economics is supposedly deduced. Indeed, economics is a highly deductive science of application, but its basic concepts and laws are empirically and inductively derived from experience. The concept of human action is not a self-evident axiom, as Mises asserts. Action is an attribute of all living organisms, human action of human beings.
 
 
2. More on the logical structure of the human mind (Human Action, 35).
 
Mises writes, “The human mind is not a tabula rasa on which the external events write their own history.” True. Reality does not write on our minds. We actively identify it.
 
“[The mind] is equipped with a set of tools for grasping reality.” True. We have tools, such as perception, conceptualization, evaluation, etc. They are mental processes that we have the innate capacity or potential to perform. And they constitute the nature or identity of consciousness. But they are not content. Tabula rasa means there is no content in our minds at birth.
 
“Man acquired these tools, i.e., the logical structure of his mind, in the course of his evolution from an amoeba to his present state.” True. “But these tools” Mises continues, “are logically prior to any experience.” They are built-in from birth, yes, and we use them, as mental tools, to identify, not passively receive, reality and to guide our choices and actions.*
 
 
3. Does Mises believe we can know reality? Yes, and this, along with his methodological individualism and emphasis on the nature of things (money, capitalism), makes him Aristotelian, or as Hülsmann (liii) says, “a representative of Aristotelian realism.” In his last book on epistemological issues, Mises writes, “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” (Ultimate Foundation of Economic Science, 6).
 
In Human Action (36), though, he is more equivocal: “It is idle to ask whether things-in-themselves are different from what they appear to us, and whether there are worlds which we cannot divine and ideas which we cannot comprehend. These are problems beyond the scope of human cognition.”**
 
To clarify, nothing is unknowable—with emphasis on the -able—to the human mind. We do not live in a phenomenal world, unable to know the noumenal. We live in reality. And the appearance of a bent stick in water is a correct perception of what looks like, or rather appears to be, a bent stick, though with the use of our sense of touch and our knowledge of the causal effects of light in water, we know that the thing-in-itself stick is not bent. (See the form-object distinction in Rand, 279-82.)
 
 
To be continued next month. At this point, let me emphasize that my comments about Mises are not meant to be serious criticisms of his work. His accomplishments are vast and exemplary, even his partially mistaken epistemology, and especially considering his professional life where he was not offered a professorship in either Vienna or New York. In spite of this he taught and wrote tirelessly as a decades-long lone voice for laissez-faire capitalism. He needs to be read.
 
 
* Ayn Rand rejects the correspondence theory of truth and the misleading notion of “grasping” reality, a relic of naïve realism (though she does use the word in a metaphorical sense). Hers is an identification theory of truth. Our minds must actively focus on reality and form those concepts to identify correctly what is “out there.” The “out there” is what Rand would say is metaphysical, whereas the “in here,” the mental processing of our consciousness, is epistemological. The empirically derived and recognized principles of the applied science of logic, and especially the law of non-contradiction, are the tools by which we judge whether or not our mental content has correctly identified reality or contradicted it.
 
** This quotation apparently is Mises’ way of dismissing as unimportant Kant’s dilemma of appearance versus reality and of asserting his emphasis on analyzing the world in which we live—the Aristotelian world. A few pages later (Human Action, 39), he writes, “Praxeology conveys exact and precise knowledge of real things,” and in Ultimate Foundation, 18, he says, “We see reality, not as it ‘is’ and may appear to a perfect being, but only as the quality of our mind and of our senses enables us to see it,” which I would take to mean reality with no Kantian distortions.
