In 1967, Jacques Derrida published 'Of Grammatology', introducing the concept of deconstruction, which critiques traditional notions of meaning and language. Derrida's work challenged logocentrism, the idea that words have fixed meanings, by emphasizing the fluidity of interpretation. This philosophical approach has had a profound impact on literary theory, cultural studies, and critical thought, reshaping how texts are analyzed and understood.

Jacques Derrida's introduction of deconstruction shattered the illusion of stable meaning, inspiring the fragmented, self-subverting, and highly playful tactics of postmodern and Language poetry. Poets like Lyn Hejinian and Charles Bernstein embraced these techniques, challenging traditional notions of authorship and interpretation.
