This new Bangla book discusses Michel Foucault's political and philosophical thoughts in the last decade of his career. The author argues that this decade was one of his most restless, creative, and fascinating. He discusses and analyses Foucauldian theories, such as sexuality, governmentality, bio-politics, and bio-power, as also his concern with the politics of truth, which includes his thoughts on modernity and critique. The book attempts to offer an intellectual history of Foucault's last decade and tries to show how a thinker thinks between the possible and the as-yet unimaginable. The author also engages with the period when Foucault positioned Kant as a critique of modernity. Through his essays on critique and Enlightenment, the author argues, Foucault was searching for another kind of critical philosophy. The essays in this book thus attempt to show the thinking in motion of an innovative intellectual of the twentieth century and in the process try to trace the finer nuances of Foucault's new critical philosophy.
