Personhood: What's in a name?

Although there are persistent metaphysical challenges to the notion of “natural kinds” of entities that are what they are essentially, all developed and useful taxonomies are based on just such notions. “Persons,” if they are to be distinguished from other kinds of things, must possess unique properties or the potential for acquiring such properties. Reductive strategies, far from locating these properties, ignore them and thus render the concept of “person” either ambiguous or unintelligible. The properties that count, it is argued here, are those associated with moral and civic forms of life.
