A metanarrative (also meta-narrative and grand narrative; French: métarécit) in critical theory--and particularly in postmodernism--is a narrative about narratives of historical meaning, experience, or knowledge, which offers a society legitimation through the anticipated completion of a (as yet unrealized) master idea.
Although first used earlier in the 20th century, the term was brought into prominence by Jean-François Lyotard in 1979, with his claim that the postmodern was characterised precisely by a mistrust of the "grand narratives" (Progress, Enlightenment, Emancipation, Marxism) that had formed an essential part of modernity.
In The Postmodern Condition: A Report on Knowledge (1979), Lyotard highlights the increasing skepticism of the postmodern condition toward the totalizing nature of metanarratives and their reliance on some form of "transcendent and universal truth":
Simplifying to the extreme, I define postmodern as incredulity toward metanarratives. ... The narrative function is losing its functors, its great hero, its great dangers, its great voyages, its great goal. It is being dispersed in clouds of narrative language ... Where, after the metanarratives, can legitimacy reside?
Lyotard and other poststructuralist thinkers (like Foucault) view this as a broadly positive development for a number of reasons. First, attempts to construct grand theories tend to unduly dismiss the naturally existing chaos and disorder of the universe, the power of the individual event.
Lyotard proposed that metanarratives should give way to petits récits, or more modest and "localized" narratives, which can ''throw off" the grand narrative by bringing into focus the singular event. Borrowing from the works of Wittgenstein and his theory of the "models of discourse", Lyotard constructs his vision of a progressive politics, grounded in the cohabitation of a whole range of diverse and always locally legitimated language-games.
Postmodernists attempt to replace metanarratives by focusing on specific local contexts as well as on the diversity of human experience. They argue for the existence of a "multiplicity of theoretical standpoints" rather than for grand, all-encompassing theories.
According to John Stephens and Robyn McCallum, a metanarrative "is a global or totalizing cultural narrative schema which orders and explains knowledge and experience" - a story about a story, encompassing and explaining other "little stories" within conceptual models that assemble the "little stories" into a whole. Postmodern narratives will often deliberately disturb the formulaic expectations such cultural codes provide, pointing thereby to a possible revision of the social code.
In communication and strategic communication, a master narrative (or metanarrative) is a "transhistorical narrative that is deeply embedded in a particular culture". A master narrative is therefore a particular type of narrative, which is defined as a "coherent system of interrelated and sequentially organized stories that share a common rhetorical desire to resolve a conflict by establishing audience expectations according to the known trajectories of its literary and rhetorical form".
Others have related metanarratives to masterplots, "recurrent skeletal stories, belonging to cultures and individuals that play a powerful role in questions of identity, values, and the understanding of life."
It is unclear whether Lyotard is describing a global condition of skepticism towards metanarratives in postmodernity, or prescribing such skepticism. His critics point out the awkward fact that meta-narratives clearly continue to play a major role in the current postmodern world.
Critics have also argued that, in so far as one of Lyotard's targets was science, he was mistaken in thinking science relies on a grand narrative for social and epistemic validation, rather than upon the accumulation of many lesser narrative successes.
