The Conservative Intellectual Movement in America since 1945
by George H Nash
If you want to know about the development of the ideas of libertarianism and Christian conservatism, it’s the best book you could read. It is perhaps the most comprehensive and surely the most readable book on the rise of post-war Christian conservatism, à la William F Buckley Jr, and of its unruly, agnostic, and finally disowned, older brother, libertarianism.
