I would now like to introduce the term mind-moment. I'm not sure quite how to define that, it may have to mean a single plank-time snapshot of a mind, or it might be as much as a couple weeks. I doubt that what I mean by this is anywhere near the upper bound I just gave, a more likely upper bound might be about a second - about the time it takes to notice something and realize something is going on.

I used to think that "mind-moments" was a good way to view personhood , but now I'm rather rather sceptical about it, because it's somewhat like trying to explain an objects movement in terms of one coordinate with one temporal coordinate; it wont tell you anything about the movement of the object. Similarly one "mind-moment" does not do anything, does not think, does not understand, does not react. I like to view it more like a process, not as moments in time. But hey my intuition might just be broken.
