Deconstruction (French: déconstruction) is a literary theory and philosophy of language derived principally from Jacques Derrida's 1967 work Of Grammatology. The premise of deconstruction is that all of Western literature and philosophy implicitly relies on a metaphysics of presence, where intrinsic meaning is accessible by virtue of pure presence. Deconstruction denies the possibility of a pure presence and thus of essential or intrinsic meaning.Derrida terms the philosophical commitment to pure presence as a source of self-sufficient meaning logocentrism. Due to the impossibility of pure presence and consequently of intrinsic meaning, any given concept is constituted and comprehended linguistically and in terms of its oppositions, e.g. perception/reason, speech/writing, mind/body, interior/exterior, marginal/central, sensible/intelligible, intuition/signification, nature/culture. Further, Derrida contends that of these dichotomies one member is associated with presence and consequently more highly valued than the other which is associated with absence. Deconstruction reveals the metaphysics of presence in a text by identifying its conceptual binary oppositions and demonstrating the speciousness of their hierarchy by denying the possibility of comprehending the "superior" element of the hierarchy in the absence of its "inferior" counterpart. Denying an absolute and intrinsic meaning to either element of the hierarchy différance is revealed (rather than proposed as an alternative) according to Derrida. Différance is a Derridaean neologism that is the antithesis of logocentrism, it is a perpetual series of interactions between presence and absence—where a concept is constituted, comprehended and identified in terms of what it is not and self-sufficient meaning is never arrived at—and thus a relinquishment of the notions of intrinsic and stable meaning, absolute truth, unmediated access to "reality" and consequently of conceptual hierarchy.To situate deconstruction within philosophy in general, it is a critique of Idealism and a form of antifoundationalism. In terms of heritage, style and conceptual framework (namely phenomenological), deconstruction is within the Continental—as opposed to analytical—tradition of philosophy.Derrida's writings on deconstruction are most strongly associated with literary criticism. However, they have also been applied to music, visual arts, feminist theory and post-colonial theory, film theory, and Post-Marxist political philosophy. Derrida's theories on deconstruction were themselves influenced by the work of linguists such as Ferdinand de Saussure (whose writings on semiotics also became a cornerstone of structuralist theory in the mid-20th century) and literary theorists such as Roland Barthes (whose works were an investigation of the logical ends of structuralist thought). Derrida's views on deconstruction stood opposed to the theories of structuralists such as psychoanalytic theorist Jacques Lacan, linguist Claude Lévi-Strauss, and political and social theorist Michel Foucault. However, Derrida resisted attempts to label his work as "post-structuralist".[citation needed]
