In a memorial volume published by the Mises Institute, Rothbard's protégé and libertarian theorist Hans-Hermann Hoppe wrote that "Man, Economy, and State" "presented a blistering refutation of all variants of mathematical economics" and included it among Rothbard's "almost mind-boggling achievements". Hoppe lamented that, like Mises, Rothbard died without winning the Nobel Prize that Hoppe says Rothbard deserved "twice over". Although Hoppe acknowledged that Rothbard and his work were largely ignored by academia, he called Rothbard an "intellectual giant" comparable to Aristotle, John Locke, and Immanuel Kant.
