Abstract

In this article I attempt to explain Kant’s notoriously obscure argument for the principle that every rational being should be treated as an “end,” and not merely as a means. I take my lead from the appearance in the argument of terms and ideas that he uses earlier in the Groundwork to express two distinctive features of moral value and to make a related claim about how moral value is achieved. I argue that, of the candidates for the “end” of moral action that Kant considers, only rational beings instantiate both of these features and satisfy the related claim. I also argue that these features and this claim explain why no other candidates need be considered and why moral actions must have an “end” at all. Thus I show that these features and this claim resolve the puzzles posed by Kant’s own argument and make sense of some of the remarks that he makes in it.
