Eleven leading contemporary French philosophers give here more or less direct presentations and exemplifications of their work. All the essays, with one exception, were specifically written for this volume and for an English-speaking readership - the exception is the first publication anywhere of Jacques Derrida's defence of his thèse d'état in 1980, based on his published works. As a collection the essays convey the style, tone and preoccupations, as well as the range and diversity, of French philosophical thinking as it is being practised today. They will stimulate and inform the rapidly growing interest in this area outside France.
