No, letís not proceed. If theyíre identical then they act the same.

That is a brilliant idea, and the fellow standing before you who looks
just like you would have the exact same brilliant idea.

Youíve proved nothing. If you poke one and not the other then they are
no longer identical and will have diverged into different people,
although both would have an equal right to call themselves Filipe

> both actually CAN NOT be identical, since [blah blah] quantum uncertainties

If your theory of personal identity is so delicate that quantum
uncertainties will disrupt it then you should never drink a cup of
coffee because it will turn you into another person; it will certainly
change you far more than quantum uncertainties will.

Itís interesting that in all these discussions everybody insists there
is a huge difference between the sacred high holy ORIGINAL and a copy,
even though the scientific method can detect no difference and the
parties in question canít even tell subjectively if theyíve switched
positions or not.
