Abstract

Ludwig von Mises’s methodological apriorism is frequently attributed to the broader Austrian School of economics, of which, of course, Mises was a prominent member. However, there is considerable controversy concerning the meaning of Mises’s various attempts to justify his apriorism. There are prima facie inconsistencies within and across Mises’s methodological writings that engender massive confusion in the secondary literature. This confusion is aggravated by the fact that Mises’s apriorism cannot be straightforwardly interpreted as an artifact of his historical milieu. Indeed, the two prevailing families of interpretation both treat Mises’s apriorism as radically anachronistic, albeit in different senses. According to “extreme” interpretations, Mises’s apriorism reflects an epistemology several decades, if not centuries, beyond its expiration date. According to “moderate” interpretations, however, Mises’s apriorism anticipates ideas that would not appear in the epistemological literature for several decades to come. Finally, there is evidence to suggest that Mises’s actual methodological beliefs are not reflected in his writings, that Mises either obfuscated or exaggerated his methodological position, for whatever reasons, making it seem more radical than it was in fact. I conclude that we have no idea what justification Mises actually intended when he asserted the a priori nature of the fundamental propositions of economics. If this is right, then, whatever method(s) they follow, Austrian economists cannot (deliberately) follow Mises’s apriorism.
