(2) should be, "Therefore, to say that a person is defined by their VBMs implies
that a person can survive as long as these same VBMs distributed among other
people's heads survive."

But that's just like saying that 1 can also mean 2 or that "blue sky" can sometimes
be red. The words imply certain conditions you must follow when assigning the
referents. If you violate these conditions you're just end up using a wrong
referent for a word and, consequently, should be using a different word. So, for
example, there's no such thing as "duplicates of personal identity" or a "gradient
of personal identity" just like there's no such thing as "two originals" or "23% of

Let's really get into this, Jef. Before I acknowledge my fault please state
precisely what your A and B are.

Again. I've always assumed that, by definition, "identity" can have at most one
referent. Are you really saying that we can stretch the meaning of this word to
include more than one thing?

You keep saying that but the truth is that (as I've tried to explain it to you
privately) it is *your* personal interpretation of the argument that makes it
circular since you continue to substitute arbitrary referents for the terms that
don't allow such freedom.
