Scheffler's paper divides into two parts. In the first, he argues that Parfit's argument from the complex view of personal identity neither can, nor is intended to, establish any moral theory; in particular, it cannot establish utilitarianism. Rather, Parfit's aim must have been simply to weaken our attachment to non-utilitarian theories. In discovering that the only philosophically respectable view of personal identity holds it to consist simply in bodily or psychological continuities and connections, we come to see that the distinctness of persons is a less deep fact than we naively supposed that it was. And this weakens the attraction of moral theories which take the distinctness of persons as fundamental and reject utilitarianism on that account. Scheffler points out that Parfit's argument cannot establish, nor can it be extended to establish, anything stronger than this. For the complex view can only rule out nonutilitarian theories if it simply denies that in any sense persons exist over time. But this view rules out not only non-utilitarian moral theories, but every moral theory.
