In Defense of "Extreme Apriorism"

The stimulating methodological controversy between Professors Machlup and Hutchison proves that there are sometimes more than two sides to every question. In many ways, the two are debating at cross-purposes: Professor Hutchison is primarily tilting against the methodological (and political) views of Professor Ludwig von Mises; his most serious charge is that Professor Machlup’s entire position is, at bottom, an attempt to cloak the Misesian heresy in the garments of epistemological respectability. Professor Machlup’s reply, quite properly, barely mentions Mises; for, in fact, their methodological views are poles apart. (Machlup’s position is close to the central “positivist” tradition of economic methodology.) But, in the meanwhile, we find that Professor Mises and “extreme apriorism” go undefended in the debate. Perhaps an extreme apriorist’s contribution to this discussion may prove helpful.
