Nihilist Communism - This is a tendency within the larger "anti-state communist" tradition. It posits a model of an essential proletariat defined by its economic position that supplants typical leftist categories of The Revolutionary Subject (the working class, oppressed peoples, a central committee, etc). Its nihilism is in reference to a negation of pre-existing approaches towards social change. It is also critical of the accompanying attitude of optimism and hope in the hypothetical movement that results from leftist models of social change.Nihilist Anarchy - As a tendency within anarchist circles nihilism refers to an explicit denial of revolutionary social change as presented by proponent of such change. In addition it draws inspiration from the Russian nihilist movement of the mid 19th century through the Illegalist movement of the early twentieth century. It argues for action driven by hopelessness and embracing of the void rather than specious connections to intentions, loyalties, or aims. Nihilist anarchists find their comrades in hoodlums, well read book clerks, and insurrectionaries-without-portfolios.
