McNay provides a clear and concise account of the development of Foucault's work and then concentrates on his later writings, where he elaborates an original theory of the self. She shows how Foucault's work on the self can be used to counter certain tendencies in feminism, such as the tendency to treat women as passive victims of systems of oppression. However, McNay argues that there are also significant shortcomings in Foucault's writings, particularly with regard to normative and political questions. Re-examining Foucault's ambivalent relation to Enlightenment thought, she shows how this relation underlies some of the most significant ambiguities and unresolved tensions in his work.
