Thank you for this great article. I particularly liked your opening remarks.
I'm also interested in why Ayn Rand did not like "The Road to Serfdom". Sad to say, I've recommended the book many times to people who I've had discussion with about the dangers of socialism. And a Hungarian co-worker once told me "Hayek is a God in Eastern Europe."
There are many books I have read and enjoyed that I have been surprised to learn are not favored by many objectivists. I've enjoyed Hayek, Popper, and Rothbard and a whole slew of libertarian and anarchist writers, like David Friedman. But I've never read any of these books by rote. That is to say, I'm not looking for a ready made philosophy to adopt wholesale out of any of these books. I find these writings INTERESTING when the author has an individualist point of view. I like feisty intelligent people who have something to say.
