Book excerpt: Originally published in 1870, this essay by the American anarchist and political philosopher Lysander Spooner is here reproduced. Described by Murray Rothbard as "the greatest case for anarchist political philosophy ever written", Spooner's lengthy essay is still referenced by anarchists and philosophers today. In it, he argues that the American Civil War violated the US Constitution, thus rendering it null and void. An indispensable read for political historians both amateur and professional alike. Many of the earliest books, particularly those dating back to the 1900s and before, are now extremely scarce and increasingly expensive. We are republishing these classic works in affordable, high quality, modern editions, using the original text and artwork.
