The same thing applies to someone who is duplicated multiple times. Each <br>
resultant person is the same in the sense that they can correctly claim <br>
to have been the original in the past, and they are all different from <br>
each other because they are now separate minds that have different <br>
experiences since the duplication. They will probably retain the same <br>
basic personality traits, and will probably express them in different <br>
ways, depending on their individual circumstances. They will each be an <br>
independent person, with the same past as all the others, up to the <br>

I'd agree with both these things: Different, and also the same, <br>

<br>
The answer to that depends on what your definition of 'identity' is, so <br>
it's a circular question. You could create a philosophical field called, <br>
say, Fish Identity Theory, that attempts to answer whether Sardines are <br>
animals or fish. There is no definitive answer to a question like this, <br>
without any other context (the most realistic answer, of course, is <br>
"both"). Insisting on one or the other is really more of an invitation <br>
to have a pointless argument than a genuine question.<br></blockquote></div></div><div dir="auto"><br></div><div dir="auto">What differentiates concerns of personal identity from taxonomy is that in there are definite hard answers to the questions or concerns: i.e. will you, or will you not experience this particular conscious experience?</div><div dir="auto"><br></div><div dir="auto">It makes no difference to the fish what we call it, but it surely makes a difference to you, whether the transporter kills you (ends your consciousness permanently), or takes you to Paris.</div><div dir="auto"><br></div><div dir="auto"><br></div><div dir="auto"><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

And I'm still no closer to understanding what 'Open Individualism' <br>
actually means. "One numerically identical subject, who is everyone at <br>
all times, in the past, present and future" is a sentence that makes no <br>
sense. What does 'One numerically identical...' mean? 'Identical' is a <br>
comparison, so you have to have at least two things, for them to be <br>
identical to one another in any respect. 'One identical thing' is <br>
meaningless. Can we replace that with "one person", for clarity, or <br>
doesn't that work?. The rest just reads as gobbledigook. Can it be <br>
boiled down to "one person, who is all people"? At least that sentence <br>
is coherent.
