MW: So far I think we can agree. (07)

MW: This is where we disagree. The object Matthew is clearly 4D
and clearly is identical to my living process having the same
spatio-temporal extent. My point was that you deny this, just
as I deny that I am a 3D object.

MW: If the pictures were of the same object, then they would all look
the same, but they do not. This is because they are pictures of states
of me at different times in my life. The states are different, and this
is why the pictures are different, but the states are all states of my
life, which is why they are all pictures of me. (012)
