To some, Jean-Paul Sartre's philosophy signaled the end of modernity. Michael Foucault's theories on the generation of the self helped to usher in the post-modern era. Kevin Boileau's work, Genuine Reciprocity and Group Authenticity argues that Sartre's insight into the positive reciprocal relationships of individuals can be understood through the Foucauldian concept of power and discourse. The book explores authenticity on individual and group levels, breaking new ground in the study of Sartre and Foucault. It is a beneficial tool for philosophers studying modern or post-modern thought.
