Michel Foucault's account of power does not foreclose the possibility of ethics; on the contrary, it provides a inescapable framework within which ethics becomes possible. A clear elaboration of both the general features common to all kinds of power relations (Chapter One), as well as the evolution of particular modes of modern power (discipline and biopower, Chapters Two and Three) demonstrates how power relations both frame and require other, ethical relations. Foucault's articulation of these ethical possibilties (Chapter Four) follows several trajectories--some rooted in contemporary politics, others in ancient ethical practices--that begin with "bodies and pleasures," and move through the communal practice of friendship, to caring for oneself and others as a critical attitude. At the core of these interconected ethical trajectories are the interwoven concepts of critique and freedom, which give Foucault the resources to articulate a provisional but sufficient justification of ethical norms and values, thus answering his most incisive and significant critics. Foucault is thus a critical theorist whose work calls us not to despair but to hope in an ongoing struggle for the good and the just.
