From Brian Doherty, “A Tale of Two Libertarians”:

“The most interesting part of Rothbard vs. the Philosophers, and the most important to libertarian intellectual history, is the notorious memo where he advised the Volker Fund, before the book came out, that F.A. Hayek’s The Constitution of Liberty should not be supported, and should be strenuously attacked when it appears. (I heard more than one prominent libertarian thinker and activist refer to the memo as horrific or scandalous, and a massive black mark on Rothbard’s reputation that could not be washed away.”
