In sociology, anthropology and linguistics, structuralism is the methodology that elements of human culture must be understood in terms of their relationship to a larger, overarching system or structure. It works to uncover the structures that underlie all the things that humans do, think, perceive, and feel. Alternatively, as summarized by philosopher Simon Blackburn, structuralism is "the belief that phenomena of human life are not intelligible except through their interrelations. These relations constitute a structure, and behind local variations in the surface phenomena there are constant laws of abstract culture".
Structuralism in Europe developed in the early 1900s, in the structural linguistics of Ferdinand de Saussure the subsequent Prague,Moscow and Copenhagen schools of linguistics. In the late 1950s and early 1960s, when structural linguistics was facing serious challenges from the likes of Noam Chomsky and thus fading in importance, an array of scholars in the humanities borrowed Saussure's concepts for use in their respective fields of study. French anthropologist Claude Lévi-Strauss was arguably the first such scholar, sparking a widespread interest in structuralism.
The structuralist mode of reasoning has been applied in a diverse range of fields, including anthropology, sociology, psychology, literary criticism, economics and architecture. The most prominent thinkers associated with structuralism include Lévi-Strauss, linguist Roman Jakobson, and psychoanalyst Jacques Lacan. As an intellectual movement, structuralism was initially presumed to be the heir apparent to existentialism. However, by the late 1960s, many of structuralism's basic tenets came under attack from a new wave of predominantly French intellectuals such as the philosopher and historian Michel Foucault, the philosopher and social commentator Jacques Derrida, the Marxist philosopher Louis Althusser, and the literary critic Roland Barthes. Though elements of their work necessarily relate to structuralism and are informed by it, these theorists have generally been referred to as post-structuralists. In the 1970s, structuralism was criticized for its rigidity and ahistoricism. Despite this, many of structuralism's proponents, such as Lacan, continue to assert an influence on continental philosophy and many of the fundamental assumptions of some of structuralism's post-structuralist critics are a continuation of structuralism.
