Max Stirner in the context of "Nihilism"

The German Ideology (German: Die deutsche Ideologie), also known as A Critique of the German Ideology, is a set of manuscripts written by Karl Marx and Friedrich Engels around April or early May 1846. Marx and Engels did not find a publisher, but the work was retrieved and first published in 1932 by the Soviet Union's Marx–Engels–Lenin Institute. The book uses satirical polemics to critique modern German philosophy, particularly that of young Hegelians such as Marx's former mentor Bruno Bauer, Ludwig Feuerbach, and Max Stirner's The Ego and Its Own. It criticizes "ideology" as a form of "historical idealism", as opposed to Marx's historical materialism (the "materialist conception of history"). The first part of Volume I also examines the division of labor and Marx's theory of human nature, on which he states that humans "distinguish themselves from animals as soon as they begin to produce their means of subsistence".

The Ego and Its Own (German: Der Einzige und sein Eigentum), also known as The Unique and Its Property, is an 1844 work by German philosopher Max Stirner. It presents a post-Hegelian critique of Christianity 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.

In 2010, John F. Welsh coined the term dialectical egoism for the thoughts of Stirner expressed in this work, in order to emphasize the distinction from the negative and pejorative connotations from the common everyday use of egoism in the sense of egotism.

Individualist anarchism in the United States was strongly influenced by Benjamin Tucker, Josiah Warren, Ralph Waldo Emerson, Lysander Spooner, Pierre-Joseph Proudhon, Max Stirner, Herbert Spencer and Henry David Thoreau. Other important individualist anarchists in the United States were Stephen Pearl Andrews, William Batchelder Greene, Ezra Heywood, M. E. Lazarus, John Beverley Robinson, James L. Walker, Joseph Labadie, Steven Byington and Laurance Labadie.

The first American anarchist publication was The Peaceful Revolutionist, edited by Warren, whose earliest experiments and writings predate Proudhon. According to historian James J. Martin, the individualist anarchists were socialists, whose support for the labor theory of value made their libertarian socialist form of mutualism a free-market socialist alternative to both capitalism and Marxism.

Individualist anarchism or anarcho-individualism is a collection of anarchist currents that generally emphasize the individual and their will over external determinants such as groups, society, traditions, and ideological systems.

Individualist anarchism can be divided into two main distinct movements, each with its own ideological orientations and choices. On one hand, there is American individualist anarchism, which began with Warren in the 1860s. It focuses primarily on economic freedom, drawing upon Stirner's egoist anarchism and Proudhon's mutualism, and develops perspectives that are notably financial in nature. Most American individualist anarchists of the 19th century advocated mutualism, a libertarian socialist form of market socialism, or a free-market socialist form of classical economics.

Egoist anarchism or anarcho-egoism, often shortened to egoism, is a school of anarchist thought that originated in the philosophy of Max Stirner, a 19th-century philosopher whose "name appears with familiar regularity in historically orientated surveys of anarchist thought as one of the earliest and best known exponents of individualist anarchism". Egoist anarchism places the individual at the forefront, crafting ethical standards and actions based on this premise. It advocates personal liberation and rejects subordination, emphasizing the absolute priority of self-interest.

James L. Walker (June 1845 – April 2, 1904), sometimes known by the pen name Tak Kak, was an American individualist anarchist of the Egoist school, born in Manchester, United Kingdom.

Walker was one of the main contributors to Benjamin Tucker's Liberty. He worked out Egoism on his own some years before encountering the Egoist writings of Max Stirner, and was surprised with the similarities. He published the first twelve chapters of Philosophy of Egoism in the May 1890 to September 1891 issues of Egoism. It was first published in book form by his widow Katharine in 1905 with the assistance of Egoism editors Henry and Georgia Replogle, the former of whom contributed prefatory remarks and a biographical sketch of Walker.
