 Strawson’s primary goal is to argue for the claim that the concept of a person is primitive, a position that he contrasts, on the one hand, with Cartesian dualism and, on the other, with what he calls the “no-ownership view”: a view according to which we don’t really self-ascribe states of consciousness at all, at least not with the use of “I” as subject (cf. Wittgenstein 1953: §244; 1958: 76; Anscombe 1975; it is controversial whether Wittgenstein ever really held this view, for discussion see Hacker 1990: chs. 5 &amp; 11; Jacobsen 1996; Wright 1998). To say that the concept of a person is primitive is, on Strawson’s account, to say that it is “logically prior” to the concepts subject and body; persons are not to be thought of as compounds of subjects and bodies. Strawson argues that the primitiveness of the concept of a person is a necessary condition of the possibility of self-consciousness (P.F. Strawson 1959: 98–103). His argument is that one can only self-ascribe states of consciousness if one is able to ascribe them to others (for more on this theme see  §4.4).  This rules out Cartesian dualism, since ascribing states of consciousness to others requires that one be able to identify others, and one cannot identify pure subjects of experience or Cartesian egos. The condition that one must be able to ascribe states of consciousness to others also rules out the “no-ownership view” because such a view is inconsistent with the fact that psychological predicates have the very same sense in their first and third person uses.
