The recently-published Hoppe festschrift, Property, Freedom, and Society: Essays in Honor of Hans-Hermann Hoppe, contains many articles of interest to Austrians and libertarians. Lew Rockwell's opening chapter, "A Life of Ideas," has a nice passage about Hoppe's ideas:
This same Hoppean effect—that sense of having been profoundly enlightened by a completely new way of understanding something—has happened many times over the years. He has made contributions to ethics, to international political economy, to the theory of the origin of the state, to comparative systems, to culture and its economic relation, to anthropology and the theory and practice of war. Even on a subject that everyone thinks about but no one really seems to understand—the system of democracy—he clarified matters in a way that helps you see the functioning of the world in a completely new light.There aren't that many thinkers who have this kind of effect. Mises was one. Rothbard is another. Hoppe certainly fits in that line. He is the kind of thinker who reminds you that ideas are real things that shape how we understand the world around us. ... Often times when you first hear a point he makes, you resist it. I recall when he spoke at a conference we held on American history, and gave a paper on the U.S. Constitution. You might not think that a German economist could add anything to our knowledge on this topic. He argued that it represented a vast increase in government power and that this was its true purpose. It created a powerful central government, with the cover of liberty as an excuse. He used it as a case in point, and went further to argue that all constitutions are of the same type. In the name of limiting government—which they purportedly do—they invariably appear in times of history when the elites are regrouping to emerge from what they consider to be near anarchy. The Constitution, then, represents the assertion of power.
When he finished, you could hear a pin drop. I'm not sure that anyone was instantly persuaded. He had challenged everything we thought we knew about ourselves. The applause was polite, but not enthusiastic. Yet his points stuck. Over time, I think all of us there travelled some intellectual distance. The Constitution was preceded by the Articles of Confederation, which Rothbard had variously described as near anarchist in effect. Who were these guys who cobbled together this Constitution? They were the leftovers from the war: military leaders, financiers, and other mucky mucks—a very different crew from the people who signed the Declaration of Independence. Jefferson was out of the country when the Constitution was passed. And what was the effect of the Constitution? To restrain government? No. It was precisely the opposite, just as Hoppe said. It created a new and more powerful government that not only failed to restrain itself (what government has ever done that?), but grew and grew into the monstrosity we have today. It required a wholesale rethinking of the history, but what Hoppe had said that shocked everyone turns out to be precisely right—and this is only one example among many.
