Libertarian Philosophers
Frederic Bastiat
Frederic Bastiat lived in the early 19th century and was quite influential on Libertarian thought. Interesting guy. Worth reading.
Libertarian Reader; Classic & Contemporary Readings From Lao-Tzu to Milton Friedman: edited by David Boaz
David Boaz is a stalwart of the Cato Institute, one of my favorite Libertarian think tanks. He’s written a wonderful book on old and new Libertarian writings. I use it frequently as a reference work, or simply to get my intellectual batteries charged.
