2012 Reprint of Original 1957 Edition. Exact facsimile of the original edition, not reproduced with Optical Recognition Software. "Mises" fourth and last great work, Theory and History (1957), has made remarkably little impact, and has rarely been cited even by the young economists of the recent Austrian revival. It remains by far the most neglected masterwork of Mises. And yet it provides the philosophical backstop and elaboration of the philosophy underlying Human Action. It is Mises" great methodological work, explaining the basis of his approach to economics, and providing scintillating critiques of such fallacious alternatives as historicism, scientism, and Marxian dialectical materialism."- Murray N. Rothbard-Preface to online edition of 2000.
