Idiots burn books for the same reason philosophers write them - they matter. But why exactly do political philosophy books matter, not to mention the hundreds of articles published every year? In part because they are interesting, but also because they are influential. They are mind-altering and, in turn, world-altering. Political philosophers write their books for the same reason political revolutionaries read them - they change the world. In this short and original book, Jonathan Floyd explains three things: what political philosophy is, how you can do it, and why you might want to. Accessibly written for those coming to the subject for the first time, it is also a must-read for scholars whose research takes in the nature, methods, and purposes of our subject. It is also a must-burn for anyone who dreams of a dumber, thicker, less enlightened world.
