Jacques Derrida’s Structure, Sign, and Play is one of the most controversial and influential philosophical texts of the 20th century. Delivered at a conference on structuralism at Johns Hopkins, the lecture took aim at the critical and philosophical fashions of the time and radically proposing a world in which meaning cannot be pinned down or traced to an origin, but instead is continuously shifting, fleeting, and open to play. Hailed by many as a watershed in philosophy and literary theory, Derrida’s lecture has shaped both disciplines. At once dense, brilliant, and humorous, it is a crucial read for anyone interested in questioning our natural assumptions about meaning in the world.
