Who propound the theory of deconstruction?

The theory of deconstruction was primarily developed by French philosopher Jacques Derrida in the late 20th century. It challenges the idea of fixed meanings in texts and emphasizes the instability of language, suggesting that meaning is always contingent and subject to reinterpretation. Derrida's work has had a profound impact on literary theory, philosophy, and critical theory, encouraging readers to question assumptions about meaning and interpretation.
