  We end this section by briefly comparing Strawson's view with Russell's and the contemporary neo-Russellian's views. We have seen that, for Russell, like Strawson, demonstrative identification plays a crucial role, in the form of acquaintance. But unlike Strawson, Russell denies that we demonstratively identify extra-mental individuals. Russell can deliver the intuitively correct results that Sally's thoughts are determinately about Bill and not Bill*, even though she is not, on Russell's view, able to demonstratively identify Bill. This is because Sally can demonstratively identify her sense data that are caused by Bill and not Bill*. On Russell's view, Sally descriptively identifies even Bill, but the descriptive condition she employs contains direct reference to her occurrent sense data. She is thus able to form a descriptive (although not purely qualitative) condition that Bill satisfies and Bill* does not. For this reason, Russell is better able to handle the reduplication argument than the Fregean.
