You are claiming that your body-map is not part of your notion of yourself?
I'm claiming that both body map and "I" are aspects of selfhood.
That is interesting because, to me, it seems like my notion of "the foot that is linked to the body that is me" is the same as my notion of "my foot."
When I step on a nail, I think "ow my foot."
Yes, those thoughts can come up.
In the context of materialism, the fact that "I" exists is hard objective evidence for "I."
Well, that might be your vision of materialism. I don't share it. To me your position is akin to a religious type claiming that "the fact that God exists is hard, objective evidence for God."
Something exists to evoke the sensation. I can define "the real father christmas" to be "whatever it is that evokes the sensation of father christmas in a child," and it becomes a trivially true fact that such a thing exists.
So, according to your vision of materialism Father Christmas exists?
Thus the real "I" exists -- it is simply whatever evokes the sensation of "I."
But is there really a sensation of "I?" I think I should not have used the word "sensation" before. There is a sensation of the body but "I" is not really a sensation. My mistake, apologies. Perhaps it would be better to use the phrase "sense of I", or "notion of I." There is a body map. There is behaviour derived from mirroring and attenting. There are thoughts. These processes go on and they maintain the sense of selfhood, but this does not mean that selfhood is real beyond this sense.
In breaking down the processes which create this sense of selfhood, including this sense of "I", so this notion of personal identity is inevitably dissipated.
In considering monism to be real, one is of course left with the question of how a monist reality can create such dualistic experiencing. This question can be dealt with here, because it can be seen that it is only with the arisal of thought and the presence of identification with thought that "I" arises. The bulk of duality is created through thinking.
No. It is only nonsense if you assume dualistic meanings for the terms involved.
If, on the other hand, you assume meanings such as "someone == a material system that human beings recognize as another human being" and "experiencing == a material process that occurs in human beings" then there is no problem at all.
Now you are, to my mind, instituting duality at an even deeper level. It's quite needless to do this imo. You are, I submit, doing just what Descartes did. He assumed that "I" must be present. He took it as a given. The pattern of identification in Descartes' brain caused this to happen so he could not see around his preconception.
There is simply no need to immerse yourself so deeply in duality. It is unnecessary to define things in such a complex manner when one appreciates that thoughts are just happening. When there is less identification the process by which a monist reality creates this dialectical reality becomes much clearer.
