Each particle can be numbered, it gives us a certain sum, but I ask about the subject and it seems that only certain particles can be part of the same subject, identical with it. If it were otherwise and the configuration of the particles would change so that they would occur in all possible relations with one another, we would not be able to talk about the identity of a person, because then we would be one. On the example I will describe it like this: I sit and write on the keyboard and my colleague in Krakow reads a book but in a different configuration, I would be a colleague reading a book and he would be writing on the keyboard. My question is the question of personal identity from the point of view of the particle of which I belong, or is it possible that certain particles belong only to me, to my personal identity. If this is not the case, you can not talk about the subject and some individual factor, but about changing the configuration of objects that are changing and individualism is falling. If it were, then as a colleague reading a book, I would be aware that I read and I would be myself, and he would write on the keyboard and it would be him, because even if all the configurations are realized, I would read the book but not the same, A book composed of those particles that belong to my consciousness, that is, who wrote on the keyboard, so it seems that there is a factor that makes the subject matter.
