ABSTRACT On the Universal Law and Humanity Formulas by Sven R. Nyholm Co-Chairs: Elizabeth S. Anderson and Sarah Buss This dissertation is a philosophical commentary on the Prussian Enlightenment philosopher Immanuel Kant’s “Universal Law” and “Humanity” formulations of the categorical imperative (i.e. the most basic principle of morality or virtuousness). The former says to choose one’s basic guiding principles (or “maxims”) on the basis of their fitness to serve as universal laws, the latter to always treat the humanity in each person as an end, and never as a means only. Commentators and critics have been puzzled by Kant’s claims that these are two alternative statements of the same basic law, and have raised various objections to Kant’s suggestion that these are the most basic formulas of a fully justified human morality. This dissertation offers new readings of these two formulas, shows how, on these readings, the formulas do indeed turn out being alternative statements of the same basic moral law, and in the process responds to many of the standard objections raised against Kant’s theory. Its first chapter briefly explores the ways in which Kant draws on his philosophical predecessors such as Plato (and especially Plato’s Republic) and Jean-Jacque Rousseau. The second chapter offers a new reading of the relation between the universal law and humanity formulas by relating both of these to a third formula of Kant’s, the “Law of Nature” formula, and also to Kant’s ideas about laws in general and human nature in particular. The third chapter considers and rejects some influential recent attempts to understand Kant’s argument for the humanity formula, and offers an alternative reconstruction instead. Chapter four considers what it is to flourish as a human being in line with Kant’s basic formulas of morality, and argues that the standard readings of the humanity formula cannot properly account for its relation to Kant’s views about the highest human good.
