 If the claim that human persons have a kind of intrinsic dignity or worth is a true objective principle and if it provides a key foundational principle of morality, it is well worth asking what kinds of metaphysical implications the claim might have. This is the question that Mark Linville (2009, 417–446) pursues in the second moral argument he develops. Linville begins by noting that one could hardly hold that “human persons have intrinsic dignity” could be true if human persons do not exist. Clearly, some metaphysical positions do include a denial of the existence of human persons, such as forms of Absolute Monism which hold that only one Absolute Reality exists. However, it also seems to be the case that some forms of Scientific Naturalism are committed to the denial of “persons as substantive selves that essentially possess a first-person point of view” (See Dennett 2006, 107). Daniel Dennett, for example, holds that persons will not be part of the ultimately true scientific account of things. Dennett holds that to think of humans as persons is simply to adopt a certain “stance” toward them that he calls the “intentional stance,” but it is clear that the kind of picture of humans we get when we think of them in this way does not correspond with their intrinsic metaphysical properties. It is not clear how systems towards which we adopt an “intentional stance” could be truly autonomous and thus have the kind of value Kant believes human persons have.
