This volume investigates Kant''s distinctive and ambitious attempt to address this problem, by arguing that norms of rationality are not merely abstract requirements of thought, but also norms of self-constitution — the very principles by which rational beings govern themselves and shape their relations with one another. On this view, morality is not imposed from the outside but arises from what constitutes a moral subject. How exactly Kant argues for this bold claim, and whether he succeeds in securing the objectivity and authority of moral obligations, remain pressing questions. These questions lie at the centre of a vigorous and expanding debate that cuts across moral philosophy, the theory of practical reason, and action theory.Bringing Kant scholarship into conversation with cutting-edge work on constitutivism, autonomy, and practical knowledge, the essays collected in this volume probe unanswered questions, refine contested distinctions, and develop new methodological tools that open fresh paths of inquiry. By combining historical depth with philosophical innovation, this volume makes a compelling case for why Kant''s account of rationality and morality remains an indispensable reference point for anyone concerned with the nature of normativity, the authority of obligation, and the self-constitution of rational agents.
