In the late 1970s, Michel Foucault dedicated a number of controversial lectures on the subject of neoliberalism. Had Foucault been seduced by neoliberalism? Did France’s premier leftist intellectual, near the end of his career, turn to the right? In this book, Geoffroy de Lagasnerie argues that far from abandoning the left, Foucault’s analysis of neoliberalism was a means of probing the limits and lacunae of traditional political philosophy, social contract theory, Marxism, and psychoanalysis. For Lagasnerie, Foucault’s analysis was an attempt to discover neoliberalism’s singularity, understand its appeal, and unearth its emancipatory potential in order to construct a new art of rebelliousness. By reading Foucault’s lectures on neoliberalism as a means of developing new practices of emancipation, Lagasnerie offers an original and compelling account of Michel Foucault’s most controversial work.
