Not everyone who talks politics knows what they’re talking about. Give them the foundation they need to win their arguments decisively by giving one of the works of a great political philosopher. We’ve located the best books by the best thinkers in the areas of liberalism, conservatism, libertarianism, communism, and anarchism. And of course a conservative will have an easier time demolishing a liberal’s arguments if he or she reads what the liberal has (or ought to have) read.
