Treating Others Merely as Means: A Reply to Kerstein

At the heart of Kantian theory lies the prohibition against treating humanity merely as a means. Two of the most influential interpretations of what this means are Wood's and O'Neill's. Drawing on these thinkers' ideas, Kerstein formulates two accounts of what is involved in the idea of treating a person merely as a means: the ‘end-sharing’ and ‘possible consent’ accounts. Kerstein's attempt is to show that they are problematic. He introduces his ‘reinforced hybrid account’ to alleviate the problems they face. I argue that the end-sharing and possible consent accounts are not vulnerable to Kerstein's criticism. However, they both face a shortcoming: they fail to support the Kantian conclusion that the prostitute and the servile person are treated merely as means. Through reconstructing these accounts, I surmount this difficulty. Moreover, my proposal helps Kerstein's own account overcome a problem he admits it has, without the need to resort to consequentialism.
