Michel Foucault wrote extensively about historical reconfigurations of knowledge in what would now be called the human sciences. During the 1970s, however, he argued (most notably in Discipline and Punish and the first volume of The History of Sexuality) that these reorganizations of knowledge also constituted new forms of power and domination. Foucault's works from this period have often generated contradictory responses from readers. His detailed historical remarks on the emergence of disciplinary and regulatory bio-power have been widely influential. Yet these detailed studies are connected to a more general conception of power, and of the epistemic and political positioning of the criticism of power, which many critics have found less satisfactory. Foucault's discussions of the relation between truth and power have similarly provoked concerns about their reflexive implications for his own analysis.

The principal purpose of this essay is to offer a sympathetic interpretation of the understanding of power and of knowledge that informs Foucault's historical studies of prisons and of the construction of a scientific discourse about sexuality. Since Foucault discussed power in this period rather more thematically than he did knowledge, my discussion of knowledge will build extensively upon his remarks about power. The essay will proceed in three parts. First I will briefly recapitulate Foucault's account of the intertwined emergence of new forms of power and knowledge in the eighteenth and nineteenth centuries. The second part will initiate my reflections upon the concepts of “power” and “knowledge” with a critical discussion of political and epistemic sovereignty.
