[Sydney Shoemaker] A major objection to the view that the relation of persons to human animals is coincidence rather than identity is that on this view the human animal will share the coincident person's physical properties, and so should (contrary to the view) share its mental properties. But while the same physical predicates are true of the person and the human animal, the difference in the persistence conditions of these entities implies that there will be a difference in the properties (...) ascribed by these predicates, with the result that the physical properties that determine the person's mental states will belong to the person and not to the human animal. /// [Galen Strawson] What are the grounds of self-consciousness? I consider 29 proposals and reject 22, including a number of proposals that experience of body (or bodies) is necessary for self-consciousness. A popular strategy in debates of this sort is to argue that one cannot be said to have some concept C (e.g. the concept ONESELF, necessary for self-consciousness) unless one has a need or a use for C given the character of one's experience considered independently of the character that it has given that one possesses C. I suggest that such arguments are invalid. (shrink)

Let thin properties be properties shared by coincident entities, e.g., a person and her body, and thick properties ones that are not shared. Thick properties entail sortal properties, e.g., being a person, and the associated persistence conditions. On the first account of realization defined here, the realized property and its realizers will belong to the same individual. This restricts the physical realizers of mental properties, which are thick, to thick physical properties. We also need a sense in which mental properties (...) can be realized in thin physical properties shared by a person and her body. Defining this in turn requires defining a sense in which the instantiations of sortal properties and of thick properties are realized in micro‐structural states of affairs. A fourth notion of realization is needed to allow for the possibility of coincident entities that share a sortal property, e.g., coincident persons. (shrink)

Any property has two sorts of causal features: “forward-looking” ones, having to do with what its instantiation can contribute to causing, and ldquo;backward-looking” ones, having to do with how its instantiation can be caused. Such features of a property are essential to it, and properties sharing all of their causal features are identical. Causal necessity is thus a special case of metaphysical necessity. Appeals to imaginability have no more force against this view than they do against the Kripkean view that (...) statements like “Gold is an element” are metaphysically necessary. (shrink)
