The Austrian School of Thought
"Intellectual curiosity has a habit of breaking through, however, especially among college and graduate students. As a result, the Austrian School has flourished over the last two decades, despite severe institutional obstacles.
In fact, the number of Austrians has grown so large, and the discussion so broad, that differences of opinion and branches of thought have arisen, in some cases developing into genuine clashes of thought. Yet they have all been conflated and jammed together by non-Austrians and even by some within the school, giving rise to a great deal of intellectual confusion, lack of clarity, and outright error.
The good side of these developing disputes is that each side has clarified and sharpened its underlying premises and world-view. It has indeed become evident in recent years that there are three very different and clashing paradigms within Austrian economics: the original Misesian or praxeological paradigm, to which the present author adheres; the Hayekian paradigm, stressing "knowledge" and "discovery" rather than the praxeological "action" and "choice," and whose leading exponent now is Professor Israel Kirzner; and the nihilistic view of the late Ludwig Lachmann, an institutionalist antitheory approach taken from the English "subjectivist"-Keynesian G.L.S.
