Post-structuralism is a label formulated by American academics to denote the heterogeneous works of a series of mid- 20th-century French and continental philosophers and critical theorists who came to international prominence in the 1960s and 1970s.
Post-structuralism is defined by its relationship to its predecessor, structuralism, an intellectual movement developed in Europe from the early to mid-20th century which argued that human culture may be understood by means of a structure—modeled on language (i.e., structural linguistics)—that differs from concrete reality and from abstract ideas—a "third order" that mediates between the two. Post-structuralist authors all present different critiques of structuralism, but common themes include the rejection of the self-sufficiency of the structures that structuralism posits and an interrogation of the binary oppositions that constitute those structures. Writers whose work is often characterised as post-structuralist include Jacques Derrida, Michel Foucault, Gilles Deleuze, Judith Butler, Jacques Lacan, Jean Baudrillard, and Julia Kristeva, although many theorists who have been called "post-structuralist" have rejected the label.
Existential phenomenology is a significant influence; Colin Davis has argued that post-structuralists might just as accurately be called "post-phenomenologists".
Usage examples of "post-structuralism".
Obviously I have lived very much out of the world: I know little of present-day Dublin or London or Paris, even less of post-modernity, post-structuralism, hard rock or rap, and I cannot write with much conviction about the contemporary scene.
