I understand that identity is too complex to figure out in this comment thread. However, any theory of identity that defines or approximates identity as “a member of a class” is apt to badly miss encapsulating most people’s understanding of identity, as illustrated by the fact that my reaction to having my own leg cut off is going to be significantly different than is my reaction to a copy of me having his leg cut off. I wouldn’t be happy about either situation, but I’d be much less happy at having my own leg cut off than I would about a copy of me having his leg cut off.
But if you don’t know who is original or copy, you may start to worry about.
Uncertainty is part of identity, I mean that any definition of identity should include some part of uncertainty, as identity is unmeasurable and undefined thing. Will it be me tomorrow? What if I am only a copy? What if my copy will be done with mistakes? All problem of identity appear in the situations when it is uncertain. And sometimes increase of uncertainty may solve this problems, as we do in indexical uncertainty.
But if you don’t know who is original or copy, you may start to worry about.
It seems to me that who is the original and who is the copy is irrelevant to my reaction in the leg amputation thought experiment. But, who is me and who is not me is very relevant. For example, suppose I am a copy of the original g_pepper. In that case, I would be less unhappy about the original g_pepper having his leg cut off than I would be about having my own leg cut off.
