Let's say we can identify a "moment of mind's creation" and we could reduce your mind back to that moment...blanking out everything after that moment. Then through some tricky dna manipulation, we change the organic structure of your brain to become the organic structure of my brain, slap it inside an Ana clone, which is then inserted into a perfectly recreated perfectly realistic simulation of my entire life (this a terrifying prospect, even for me

).
Would you then be me?
Yes, though in a minimalistic sense. More on that below.
(My guess is that you'll say at the moment of reduction back to creation, nothing of you will remain...or shortly thereafter)
That is true, but really we're getting into the "Star Trek transporter" philosophical puzzles. If Scotty beams you up, is the recreated "you" actually "you". And if a copy of you is made by accident, is that "you" as well?
My answer to those scenarios is
yes.
Let's start with Wesley Crusher. He steps into the transporter, and a transporter accident makes him unrecoverable. Now imagine a line (not a perfectly straight line, but one that wanders a little) drawn on paper that comes to an abrupt end. Goodbye Wesley Crusher. His life is over.
Now consider a successful transport of Captain Picard. Imagine a line that has a very tiny break (during the destruction and recreation by the transporter), but clearly continues on from where it was. His life continues as Picard as if the break had never really happened. Welcome aboard, Captain!
Now let's consider William Riker. He is accidentally duplicated during transportation. Now imagine a line that has a very tiny break as in the first example, and re-emerge at the same point, but that point leads to two lines that slowly diverge. Riker was split into two Rikers who live different lives from that point on, but are still both "Riker".
In your example, everything starts at the same point, and then two lines diverge just as with the transporter duplicates. This is "minimalistic" since one never starts with a line, but with only a point.
I hope you are getting at what I mean by the lines. I'm talking about a path of development into the future. At any one point on the line you have a particular mental state. Perhaps it is the exact state of your neurons at that moment. The line is a plot of the change of state over time as you gain new experiences, act on your circumstances, and are changed by your choices and experiences.
Keep in mind that I don't view selfhood as pertaining only to slices in time. I view it as pertaining to the pattern of one's development across a lifetime. Selfhood for me is the
line.
When two lines diverge, it is their shared history as one line (or in the minimalistic case, one point) that entitles one to view the lines as the same "self". I would say that the two Rikers are indeed Riker, even though their "lines" had diverged. Sure, one can focus on a slice of time and declare that their states are not identical, but that is the sort of thinking that would lead one to not see Riker of even one minute ago as Riker.
It's not unreasonable to make a distinction between the two Rikers. In a certain respect, they are two different persons. The lines
have diverged. But in another respect, they are the same person. They are both Riker.
I think that the respect in which they are both Riker is compelling enough to make the claim that I'm making. If selfhood is seen as a dynamic pattern that takes place over time, and not a "snapshot" in time, then we can identify our selves with our past, and you can be the "same" (but not identical) self as you were when you started reading my post.
So maybe a more interesting question would be, do you think you would do everything as I had? Is that a little too deterministic?
Since I believe in a limited form of free will then, no, I don't think that I would necessarily lead an identical life in identical circumstances.
eudaimonia,
