Michel Foucault was one of the twentieth century’s most influential thinkers whose work has unsettled and transformed the field of social philosophy and the social sciences. The essays and articles selected for this volume are written by many of the most important of Foucault’s interpreters and interlocutors and show the range of Foucault’s influence and the debates it has provoked about Foucault’s own approaches and in relation to substantive areas of social philosophy and social science such as power, critique, enlightenment, law, governance, ethics and truthfulness. This volume provides a comprehensive introduction to, and overview of, the development of Foucault’s thought and demonstrates its enduring significance on our understanding of how we have become what we are.
