os dois libertarianismos

But as Rothbard makes abundantly clear here, very important differences exist between the fallibilistic, utilitarian, small-government thinking of Hayek (and Friedman, and to a great degree Mises) and the rights-based anarchism of Rothbard and many of his followers, both of which coexist uneasily under the label libertarian.

In words that he never made or intended to make public in his lifetime, Rothbard calls Hayek’s most monumental statement about liberty and the political order “surprisingly and distressingly, an extremely bad, and, I would even say, evil book.” The “evil” part comes from the blow he thinks it will strike the libertarian movement, with Hayek then and even more later seen as libertarianism's most respectable and brilliant exponent.
