Abstract

Whether the justification at stake is ethical or juridical, all attempts to argue for the welfare principle in Kant’s metaphysics of morals are unsuccessful. This principle cannot be justified a priori in Kant’s context. However, it is not only possible but also necessary to argue for a certain degree of social welfare in politics as the practice of right; otherwise, Kant’s project of political practice, with enlightenment as its core concept, will inevitably fail. Enlightenment requires that the state be committed to reducing the impact of an unequal social structure on individuals so as to preserve the possibility of their enlightenment. However, it also imposes limits on state-sponsored social welfare because excessive social welfare could lead to a general minority.
