Abstract

Descartes made vivid that my certainty as to which psychological states are mine seems to outrun by far my certainty about which body is mine, or even that I have a body. This can make it seem compelling that in our ordinary use of the first person, we are referring to purely psychological subjects, which just so happen to be specially related to particular bodies. This would explain why your certainty about your ownership of a particular psychological life can outrun your certainty about your ownership of a body. The problem is that it is difficult to make sense of this notion of the self as a purely psychological subject.
