Johann Kaspar Schmidt (October 25, 1806 – June 26, 1856), better known as Max Stirner, was a German philosopher. He is often seen as one of the forerunners of nihilism, existentialism, psychoanalytic theory, postmodernism, and individualist anarchism.[3][4] Stirner's main work is The Ego and Its Own, also known as The Ego and His Own (Der Einzige und sein Eigentum in German, which translates literally as The Individual and His Property[5][6]). This work was first published in 1845 in Leipzig, and has since appeared in numerous editions and translations.
