third, that it considers humans by nature to be active and productive; fourth, it holds the belief of human equality; and fifth, that history is progressive and will create positive change on the condition that humans work to achieve such change. Anarchism Anarchism advocates stateless societies often defined as self-governed voluntary institutions, but that several authors have defined as more specific institutions based on non-hierarchical free associations. While anarchism holds the state to be undesirable, unnecessary or harmful, it is not the central aspect. Anarchism entails opposing authority or hierarchical organisation in the conduct of human relations, including the state system. Mutualists support market socialism, collectivist anarchists favour workers cooperatives and salaries based on the amount of time contributed to production, anarcho-communists advocate a direct transition from capitalism to libertarian communism and a gift economy and anarcho-syndicalists prefer workers' direct action and the general strike. The authoritarian–libertarian struggles and disputes within the socialist movement go back to the First International and the expulsion in 1872 of the anarchists, who went on to lead the Anti-authoritarian International and then founded their own libertarian international, the Anarchist St. Imier International. In 1888, the individualist anarchist Benjamin Tucker, who proclaimed himself to be an anarchistic socialist and libertarian socialist in opposition to the authoritarian state socialism and the compulsory communism, included the full text of a "Socialistic Letter" by Ernest Lesigne in his essay on "State Socialism and Anarchism". According to Lesigne, there are two types of socialism: "One is dictatorial, the other libertarian". Tucker's two socialisms were the authoritarian state socialism which he associated to the Marxist school and the libertarian anarchist socialism, or simply anarchism, that he advocated. Tucker noted that the fact that the authoritarian "State Socialism has overshadowed other forms of Socialism gives it no right to a monopoly of the Socialistic idea". According to Tucker, what those two schools of socialism had in common was the labor theory of value and the ends, by which anarchism pursued different means. According to anarchists such as the authors of An Anarchist FAQ, anarchism is one of the many traditions of socialism. For anarchists and other anti-authoritarian socialists, socialism "can only mean a classless and anti-authoritarian (i.e. libertarian) society in which people manage their own affairs, either as individuals or as part of a group (depending on the situation). In other words, it implies self-management in all aspects of life", including
