Because of their range, brilliance, and singularity, the ideas of the philosopher-critic-historian Michel Foucault have gained extraordinary currency throughout the Western intellectual community. This book offers a selection of seven of Foucault's most important published essays, translated from the French, with an introductory essay and notes by Donald F. Bouchard. Also included are a summary of a course given by Foucault at College de France; the transcript of a conversation between Foucault and Gilles Deleuze; and an interview with Foucault that appeared in the journal Actuel. Professor Bouchard has divided the book into three closely related sections. The four essays in Part One examine language as a "perilous limit" of what we know and what we are. The essays in the second part suggest the methodological guidelines to which Foucault subscribes, and they record, in the editor's words, "the penetration of the language of literature into the domain of discursive thought." The material in the last section is more obviously political than the essays. It treats language in use, language attempting to impart knowledge and power. Translated by the editor and Sherry Simon into fluent and lucid English, these essays will appeal primarily to students of literature, especially those interested in contemporary continental structuralist criticism. But because of the breadth of Foucault's interests, they should also prove valuable to anthropologists, linguists, sociologists, and psychologists.
