Why Everything You Were Taught About Truth Is a Hierarchy in Disguise | Derrida

For twenty-five centuries, Western philosophy trusted one silent assumption above all others: that the voice carries truth, and writing merely records it. Jacques Derrida read that assumption like a surgeon reads an x-ray — not to admire the bone, but to find the fracture. In this deep dive, we trace Derrida's most radical ideas — logocentrism, the metaphysics of presence, différance, dissemination, and the logic of the supplement — through his landmark works Of Grammatology, Speech and Phenomena, and Writing and Difference. We examine how he dismantled Plato, Rousseau, Saussure, and Husserl from inside their own texts, and why his method still shapes how we think about language, power, and meaning today. This is not a textbook summary. This is the story of a man who asked one embarrassingly simple question — why do we trust speech more than writing? — and watched a cathedral of certainty come apart.
