<br>
Yes, of course. And if the person stepping into the transporter
thinks that his consciousness depends on the atoms of his brain (or
an immaterial 'soul' that is lost, etc.), the person stepping out of
the other end will believe that he is not the same person. There is
a character in Charlie Stross' Accelerando in exactly this position.
No-one can convince him of their view that he is the same person,
despite his continuity of memory, etc. Can we say he's wrong? Only
by asserting that a different way of looking at things is the
'correct' one. Can he say that they are wrong? Ditto. Yes, you can
demonstrate that a mind survives replacement of the atoms in the
brain (or does it? Maybe it's a mind that's to similar to the
original that no-one else notices), but in the end, you have to
choose a framework and follow it through.<br>
<br>
Someone else may think that they are only partially the same person.<br>
<br>
Most would probably think that they are the same person (why would
you undergo the procedure otherwise, unless it was forced on you?)<br>

So, different points of view, different answers.<br>

I suppose you could say that, being careful to recognise that the

I thought we'd agreed on the unique nature of experiences. You can't

really 'have' a life which includes many different mind-states. I'd
rather say a person consists of many different mind-states. If those

I have no idea how you'd determine that. There must be limits,

I can't say for sure, but I suspect that the experience of [anything
you like] is different as my mind changes over time. That each
experience is unique not only to a mind, but to a mind at a specific
time. It could be that someone's experience of eating a cheese
sandwich on a rainy afternoon in March 2019 is different to the same

My point is that experiences are unique. Not only to the minds
generating them, but quite probably to each instance of 'the same'
experience (meaning that they aren't in fact the same at all. The
uniqueness is absolute). This means there is no such thing as two
people having the same experience, or a common pool of experiences
that can be 'had' by a number of different people.<br>
