 Many philosophers find Immanuel Kant’s moral philosophy still offers a fruitful approach to ethics. Of the various forms of the “categorical imperative” that Kant offers, the formula that regards human beings as “ends in themselves” is especially attractive: “Act in such a way that you always treat humanity, whether in your own person or in the person of any other, never simply as a means, but always at the same time as an end” (Kant 1785 [1964], 96). Many contemporary moral philosophers influenced by Kant, such as Christine Korsgaard (1996), see Kant as offering a “constructivist” metaethical position. Constructivism is supposed to offer a “third way” between moral realism and subjectivist views of morality. Like subjectivists, constructivists want to see morality as a human creation. However, like moral realists constructivists want to see moral questions as having objective answers. Constructivism is an attempt to develop an objective morality that is free of the metaphysical commitments of moral realism.
