Allen W. Wood Quote
I think Kantian ethics must [...] reject the unity of the person account. A more consistent Kantian approach is based on the idea that we can treat, or fail to treat, rational nature as an end in itself not only in the person of a rational being in the strict sense but also in the way we treat other beings who are not persons in the strict sense.
