October 22, 2001 Personal IdentityⅢ . Review soul criterion and body criterion Soul criterion: x is the same person as y iff and y have the same soul. Problems: i)There is no way to establish body-soul correlations; and no way to establish personality correlations. So soul criterion doesn't make sense of our practices of recognizing and identifying people ii)We have no special access to souls, so even in our own case we can't be sure it's the same soul \inside\ us whenever we are conscious. ii) The problem of identity is \pushed back\: what is it for person-stage x to have the same soul as person-stage y? What makes for sameness of souls? Body criterion: x is the same person as y iff x and y have the same living human body
