The most revolutionary book ever published . [Stirner] has left behind him a veritable Breviary of Destruction, a striking and dangerous book. It is dangerous in every sense of the word-to socialism, to politicians, to hypocrisy. But it asserts the dignity of the Individual, not his debasement.
New York Times
You will have heard of Stirner's book, <i>The Ego and His Own</i> . And it is certainly true that we must first make a cause our own, egoistic cause . we are communists out of egoism also, and it is out of egoism that we wish to be human beings, not mere individuals.
- Friedrich Engels to Karl Marx, 19 November 1844,
