In Rothbard’s “In Defense of “Extreme Apriorism”,” Rothbard makes this statement about the status of the action axiom:
"Whether we consider the Action Axiom “a priori” or “empirical”
depends on our ultimate philosophical position. Professor Mises, in the neo-
Kantian tradition, considers this axiom a law of thought and therefore a
categorical truth a priori to all experience. My own epistemological position
rests on Aristotle and St. Thomas rather than Kant, and hence I would
interpret the proposition differently. I would consider the axiom a law of
reality rather than a law of thought, and hence “empirical” rather than “a
priori.” But it should be obvious that this type of “empiricism” is so out of
step with modern empiricism that I may just as well continue to call it a priori
for present purposes. For (1) it is a law of reality that is not conceivably
falsifiable, and yet is empirically meaningful and true; (2) it rests on universal
inner experience, and not simply on external experience, that is, its evidence
is reflective rather than physical7; and (3) it is clearly a priori to complex
historical events.8
8 Professor Hutchison may have had me in mind when he says that in recent years followers of
Professor Mises try to defend him by saying he really meant “empirical” when saying “a priori.”
Thus, see my “Praxeology, Replay to Mr. Schuller,” American Economic Review (December
1951): 943-44. What I meant is that Mises’s fundamental axiom may be called “a priori” or
“empirical” according to one’s philosophical position, but is in any case a priori for the practical
purposes of economic methodology."
Why exactly does Rothbard make this distinction as to the nature of the action axiom? What is meant by a “law of thought” and a “law of reality?” What are the fundamental differences between Kantian and Aristotilian/Thomist philosophical positions?
Reading Hoppe’s Economic Science and the Austrian Method, he defends Mises’s position on the action axiom as being “a priori.” Is Hoppe a Kantian? What arguments are there against Rothbard’s Aristotilian/Thomist position?
I also remember reading in Human Action Mises’s criticism of the natural law. Are these and other arguments against natural law valid? Are there any other arguments against the natural law that would apply to this discussion?
Also as a side issue, I have befriended a PhD student of anthropology. He also takes the position that there is no natural law. More importantly, however, he argues that individualism doesn’t exist. Where can I find these arguments being made? What are your thoughts on these postitions? Has there been any successful refutation or validation of such concepts? If so, what are they and where can I find more information?
Don’t be shy. Indulge! I would love to see where this goes. I’m having a hard time continuing my readings with these thoughts stuck in my brain.
