I’m about 1/3 of the way through Brian Doherty’s excellent Radicals for Capitalism: A Freewheeling History of the Modern American Libertarian Movement. I had read a few chapters in manuscript form and have been looking forward to the work for some years. I’m pleased to say that the wait has been worth it. I’ll write more about it soon (after I’ve finished the whole 718 pages of text, of course.)
