Post-anarchism or postanarchism is an anarchist philosophy that employs post-structuralist and postmodernist approaches (the term post-structuralist anarchism is used as well, so as not to suggest having moved beyond anarchism). Post-anarchism is not a single coherent theory, but rather refers to the combined works of any number of post-structuralists such as Michel Foucault, Gilles Deleuze, Jacques Lacan; postmodern feminists such as Judith Butler; and post-Marxists such as Ernesto Laclau, Chantal Mouffe, Jacques Rancière; with those of the classical anarchists, with particular concentration on Emma Goldman, Max Stirner, and Friedrich Nietzsche. Thus, the terminology can vary widely in both approach and outcome.
