1930 – 2004
Jacques Derrida (1930–2004) was an Algerian-born French philosopher widely regarded as the founder of deconstruction, a method of critical analysis that interrogates the hierarchical oppositions and unstated assumptions underlying Western philosophical and literary texts. His work fundamentally challenged logocentrism—the privileging of speech over writing and presence over absence—in the Western metaphysical tradition. Derrida's influence extends across philosophy, literary theory, legal studies, architecture, and theology.
