His work inspired the school of deconstruction

Focuses on language.

Subverts narrative assumptions about the text and challenges the idea that a text has an unchanging, unified meaning.

By deconstructing the works of previous scholars, Derrida attempts to show that language is constantly shifting.

Shows the unavoidable tensions between the ideals of clarity and coherence that govern philosophy and the inevitable shortcomings that accompany its production.
