The context is as follows:
MILLER: I see. But wait. I believe my problem is that I simply forgot a main tenet of my theory. The correlation can be established in my own case. I know that my soul and my body are intimately and consistently found together. From this one case I can generalize, at least as concerns life in this world, that sameness of body is a reliable sign of sameness of soul. This leaves me free to regard it as intelligible, in the case of death, that the link between the particular soul and the particular body it has been joined with is broken.
