This is an important new critical analysis of Derrida's theory of writing, based on close readings of key texts. It reveals a dimension of Derrida's thinking that has been neglected in favor of those "deconstructionist" cliches favored by much recent literary criticism. Christopher Johnson highlights the special character of Derrida's philosophy that comes from his contact with contemporary natural science and with systems theory. This study casts new light on an exacting set of intellectual issues facing philosophy and critical theory today.
