The Ego and His Own: The Case of the Individual Against Authority,

The Ego and Its Own (German: Der Einzige und sein Eigentum; meaningfully translated as The Individual and his Property, literally as The Unique and His Property) is an 1844 work by German philosopher Max Stirner. It presents a radically nominalist and individualist critique of Christianity, nationalism, and traditional morality on one hand; and on the other, humanism, utilitarianism, liberalism, and much of the then-burgeoning socialist movement, advocating instead an amoral (although importantly not inherently immoral or antisocial) egoism. It is considered a major influence on the development of anarchism, existentialism, nihilism, and postmodernism.
