11. Personal identity in change of substance.
That this is so, we have some kind of evidence in our very bodies, all
whose particles, whilst vitally united to this same thinking conscious self, so that we feel when they are touched,
and are affected by, and conscious of good or harm that happens to them, as a part of ourselves; i.e., of our
thinking conscious self. Thus, the limbs of his body are to every one a part of Himself; he sympathizes and is
concerned for them. Cut off a hand, and thereby separate it from that consciousness he had of its heat, cold, and
other affections, and it is then no longer a part of that which is himself, any more than the remotest part of matter.
Thus, we see the substance whereof personal self consisted at one time may be varied at another, without the
change of personal identity; there being no question about the same person, though the limbs which but now were
a part of it, be cut off.
