Michel Foucault's death in 1984 coincided with the fading away of the hopes for social transformation that characterized the postwar period. In the decades following his death, neoliberalism has triumphed and attacks on social rights have become increasingly bold. If Foucault was not a direct witness of these years, his work on neoliberalism is nonetheless prescient: the question of liberalism occupies an important place in his last works. Since his death, Foucault's conceptual apparatus has acquired a central, even dominant position for a substantial segment of the world's intellectual left. However, as the contributions to this volume demonstrate, Foucault's attitude towards neoliberalism was at least equivocal. Far from leading an intellectual struggle against free market orthodoxy, Foucault seems in many ways to endorse it. How is one to understand his radical critique of the welfare state, understood as an instrument of biopower? Or his support for the pandering anti-Marxism of the so-called new philosophers? Is it possible that Foucault was seduced by neoliberalism?
