Giuseppe Peano was an Italian mathematician and glottologist. The author of over 200 books and papers, he was a founder of mathematical logic and set theory, to which he contributed much notation. The standard axiomatization of the natural numbers is named the Peano axioms in his honor. As part of this effort, he made key contributions to the modern rigorous and systematic treatment of the method of mathematical induction. He spent most of his career teaching mathematics at the University of Turin. He also wrote an international auxiliary language, Latino sine flexione, which is a simplified version of Classical Latin. Most of his books and papers are in Latino sine flexione, while others are in Italian.
Johann Kaspar Schmidt, known professionally as Max Stirner, was a German post-Hegelian philosopher, dealing mainly with the Hegelian notion of social alienation and self-consciousness. Stirner is often seen as one of the forerunners of nihilism, existentialism, psychoanalytic theory, postmodernism and individualist anarchism.

The following outline is provided as an overview of and topical guide to anarchism:
Heinrich Hössli, sometimes written as Hößli, was a Swiss hatter and author. His book Eros Die Männerliebe der Griechen surveyed references to same-sex love in ancient Greek literature and more recent research, and was one of the first works in the 19th century that defended love between men.
Ferdinand Anton Franz Karsch was a German arachnologist, entomologist and anthropologist. He also wrote on human and animal sexual diversity with his mother's maiden name included as FerdinandKarsch-Haack from around 1905.
Egoist anarchism or anarcho-egoism, often shortened as simply 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.
Die Anarchisten: Kulturgemälde aus dem Ende des XIX Jahrhunderts is a book by anarchist writer John Henry Mackay published in German and English in 1891. It is the best known and most widely read of Mackay's works, and made him famous overnight. Mackay made it clear in the book's subtitle that it was not intended as a novel, and complained when it was criticised as such, declaring it instead propaganda. A Yiddish translation by Abraham Frumkin was published in London in 1908 by the Worker's Friend Group, with an introduction by the journal's editor, prominent London anarchist Rudolf Rocker. It was also translated into Czech, Dutch, French, Italian, Russian, Spanish, and Swedish. Die Anarchisten had sold 6,500 copies in Germany by 1903, 8,000 by 1911, and over 15,000 by the time of the author's death in 1933.
Major anarchist thinkers, past and present, have generally supported women's equality. Free love advocates sometimes traced their roots back to Josiah Warren and to experimental communities, viewing sexual freedom as an expression of an individual's self-ownership. Free love particularly stressed women's rights. In New York's Greenwich Village, "bohemian" feminists and socialists advocated self-realisation and pleasure for both men and women. In Europe and North America, the free love movement combined ideas revived from utopian socialism with anarchism and feminism to attack the "hypocritical" sexual morality of the Victorian era.
The mathematical manuscripts of Karl Marx are a manuscript collection of Karl Marx's mathematical notes where he attempted to derive the foundations of infinitesimal calculus from first principles.
German individualist philosopher Max Stirner became an important early influence in anarchism. Afterwards Johann Most became an important anarchist propagandist in both Germany and in the United States. In the late 19th century and early 20th century there appeared individualist anarchists influenced by Stirner such as John Henry Mackay, Adolf Brand and Anselm Ruest and Mynona.
The Young Hegelians, or Left Hegelians (Linkshegelianer), or the Hegelian Left, were a group of German intellectuals who, in the decade or so after the death of Georg Wilhelm Friedrich Hegel in 1831, reacted to and wrote about his ambiguous legacy. The Young Hegelians drew on his idea that the purpose and promise of history was the total negation of everything conducive to restricting freedom and reason; and they proceeded to mount radical critiques, first of religion and then of the Prussian political system. They rejected anti-utopian aspects of his thought that "Old Hegelians" have interpreted to mean that the world has already essentially reached perfection.
Der Kreis was a Swiss gay magazine. Founded as the lesbian magazine Freundschaftsbanner in 1932 it turned into a male-only magazine in 1942 under the name Der Kreis. It was trilingual and distributed internationally and gained significant influence in the homosexual movement at the time until it ceased publication in 1967.
