pIn this remarkable book Michel Foucault, one of the most influential thinkers of recent times, calls us to look critically at specific historical events in order to uncover new layers of significance. In doing so, he challenges our assumptions not only about history, but also about the nature of language and reason, even of truth. The scope of such an undertaking is vast, but by means of his uniquely engaging narrative style, Foucault's penetrating gaze is skilfully able to confront our own. After reading his words our perceptions are never quite the same again.p
