Mises and Popper on Action

 Today the Ludwig von Mises Institute published my short article, "Mises and Popper on Action," a result of my joint project with Rafe Champion to explore the synergy between Popper and the Austrians (The Austrian School of Economics as a Popperian Metaphysical Research Programme).

If two schools of thought seem to be not only right, but incompatible, there are only two choices: 1) one or both of them are wrong; or 2) their differences may be resolved through semantic reconciliation and the discarding of mistakes that are of minor consequence. Rafe and I have been on the latter path for some time and hope our work encourages others to take the same path.

Reflections on Presenting at the Southern Economic Association/Society for the Development of Austrian Economics Conference of 2023

 I believe this year's conference was the last one I will attend. It's not so much that it was a waste of time and money, but that I very much doubt that I have another paper in me. In fact, there was only a mass of paragraphs underlying my presentation, not a paper.

The title of my presentation was "Biophilosophy and Praxeology" in which I made many assertions that I expected would be challenged or at least would produce a request for elaboration in the Q&A period. As there was only 15 minutes for the presentation, you can imagine that many things were glossed over, including the apriorism that is surfacing in biophilosophy and the idea that Ludwig von Mises should have looked to biology rather than philosophy for the source of his apriorism. In fact, when I would wake up in the middle of the night, I spent a lot of time thinking about how I would address the vast array of possible questions that would require deeper explanations of my thinly supported assertions.

At the very end of the paper there is a short example of how an a priori concept in biology, metabolism and the requirement of binding and releasing energy (Mayr), could lead to the creation of goods and the process of evolution that Menger described in development of money. For some reason, this example became the exclusive focus of questioning by the session organizer and then, in open discussion, by other participants. I was corrected from the floor that the definition of money is the generally accepted means of exchange rather than the most liquid commodity.

In addition, there was very little follow-up after the end of the session in which people like to engage in private discussion. Apparently, nobody liked it, and nobody hated it—a non-event. At the SDAE dinner one student said he liked the presentation and found it interesting.

Note that no one told me that I was rehashing old material that was more clearly or rigorously presented in the past or had misinterpreted the material I was citing. Perhaps it was the emphasis that this year seemed much more empirical than in previous years. Maybe there simply is no interest in rescuing the apriorism of the Misesian program of praxeology from the evolutionary empirical emphasis that dominates the Hayekian mind set.

It only remains for me to seek an alternative path, possibly through the biophilosophers. Do I have confidence of a different result in that direction? Who knows—pigs may fly!

Ludwig von Mises, the Action Axiom, and Biology

Introduction

In the pursuit of science little can be said to be of greater importance than the epistemology employed.  In this regard the epistemology of the Austrian School of economic thought has been roundly criticized and rejected by mainstream economists.¹  This reaction was primarily due to Ludwig von Mises's firm stand on apriorism and the claim that praxeology, of which economics was the most developed discipline, was a new science, unconnected to previously acquired knowledge (Mises, 1966, 1-10).

Much of the Austrian literature on epistemology since Mises's exposition² has been to explain and defend, ever more loudly and vociferously, apriorism and the apodictic certainty of conclusions derived from Mises's action axiom.  A notable exception to that literature is Barry Smith's tract on fallible apriorism (1996), which elaborated and extended Rothbard's thesis (1957) by showing that a priori knowledge, although independent of observation, is derived from observation and, hence, is synthetic a priori knowledge.

With Smith's introduction of fallibilism into Mises's system, some of the distance between it and Karl Popper's concept of conjectural knowledge was reduced.  This reconciliation has been visible in a number of efforts that attempt to bring Mises's approach into the methodological housing of Popper and other philosophers of science, notably Imre Lakatos.³  More on that in another post; but, at this moment we have another issue to address — Mises's claim that economics, and its encompassing science, praxeology, are new sciences unconnected with previous knowledge.  This claim did not sit well with those who believe all knowledge to be connected and do not have an anthropocentric view of the universe.

The Origins of Action

Mises went to great lengths to deny that human action is in any way related to action in our evolutionary ancestors, even stating that "The newborn child is not an acting being," and that "Beings of human descent who either from birth or from acquired defects are unchangeably unfit for any action... are practically not human" (1966, 14).  To do so seems to strike at the very notion that we have evolved from species that have less flexibility than we, and from whom we do not stand apart in the universe.  In this context Mises formulated what has become known as the action axiom — man acts, aiming at the improvement of his situation relative to his values (1966, 13-14).

In an address given in 1967, Karl Popper made a more general statement — that "Animals, and even plants, are problem-solvers" (1972, 145).  The idea was later stated more simply as "All life is problem solving" (1999, 100).  By this statement he meant that each life form represented, either anatomically or behaviorally, a hypothetical solution to the problem of its environment. Darwinian evolution supplied the criticism or falsification of that hypothesis.

At this point we must ask, "what problem is being solved?"  The answer lies in the action axiom — the problem of improving the situation, or survivability, of the organism.  Each organism acts, in the way it understands, to improve its situation.⁴  It appears that Popper's statement stands as a powerful axiom — possibly the basic axiom of biology — in support of Mises's more specific one and reveals biology as the epistemological basis of economics.  In fact economics is not separated from all of the other sciences, but is an outgrowth of biology.

This conclusion would most likely suit Edward O. Wilson who said "It is in biology and psychology that economists and other social scientists will find the premises needed to fashion more predictive models, just as it was in physics and chemistry that researchers found premises that upgraded biology" (1998, 206); however, Wilson did not expect the basic premise to come from a philosopher or support the Austrian methodological approach.

We do not argue here that economics has that much to learn from biology, although Wilson certainly believes it does.  Economics is clearly a human science — the most fundamental theorems depend on activities that are observable only in humans.  What we do argue is that biology supplies an axiom that is fundamental to all life that strengthens Mises's action axiom, supporting it with what Rothbard would have called a "law of reality rather than a law of thought" (1957).

At this point we must question why Hayek did not see this connection.  He knew, and was friends with, both Mises and Popper, as well as having a deep understanding of their work.  He also came from a family of biologists.  His father was a serious botanist as well as being a doctor, and Hayek helped him with botanical work and attended society meetings (Ebenstein, 2001).  At this point we can only speculate, but he may have seen Mises's and Popper's works as irreconcilable and never even contemplated a reconciliation of their views.  Perhaps he was reluctant to start down a path that could have resulted in the loss of one or both of his closest intellectual associates.  In any case, it is unfortunate that a person of his stature did not complete Mises's work by linking economics with the rest of knowledge.

Conclusion

With the modification of Mises's viewpoint on action yet another objection to the epistemology of the Austrian School can be overcome.  This modification is hardly a blow to Mises's overall system as it supports, rather than rejects, his action axiom.  At the same time it ties economics more closely to the sciences, a goal that we can only believe Mises would have supported.
