First published in 1967, "Writing and Difference, " a collection of Jacques Derrida's essays written between 1959 and 1966, has become a landmark of contemporary French thought. In it we find Derrida at work on his systematic deconstruction of Western metaphysics. The book's first half, which includes the celebrated essay on Descartes and Foucault, shows the development of Derrida's method of deconstruction. In these essays, Derrida demonstrates the traditional nature of some purportely nontraditional currents of modern thought - one of his main targets being the way in which "structuralism" unwittingly repeats metaphysical concepts in its use of linguistic modes.
