If the body isn't 'yours' why and what is this 'hope?
Sorry, I poorly conveyed that. That was just a sort of half-joke I threw in after the implied assumption that I wouldn't have any serious bodily problems in the near future.
Look in a mirror for me and describe in direct experience what is seen?
The body and it's surroundings are seen, and that is all that is present in direct experience in the most literal sense of the word "seen". Thoughts are also "seen", and many immediately appear and comment on the body. Some say something along the lines of the body being an important investment that has been built up over the years. Others say "this is all you really have". I let these thoughts run their course and settle down while I continued looking, to see if anything else was noticeably present or absent. One such thing was a sense of inside or outside; the body and the environment present in the mirror were all clearly one interacting system, with no inside/outside separation around the body.
Then look at a photo of you as a child. What comes up?
The feeling that this is a completely different person that I am looking at. We have(had, in his case) different personalities, preferences, memories, physical appearance, etc. There are many other people that I have more in common with than child-me. I expected to sense some sort of continuity with my younger self, like that person was one stage in the linear progression called "Bruce's life." Strangely enough, I also felt a brief twinge of mild embarrassment at the recollection of a childhood memory I associated with the picture. I'm not sure what to make of that lack of identification coupled with a memory being experienced as having happened to Me.
Are they 'you?
No. They were
me in the same sense that the experiences participated in by this body and mind are
me now; that is, only in a conventional and social sense. I say that they are not me because a past person (much less a past 'I') cannot be pointed to in present experience. We can have memories made up of words and images that reference these past selves, but they are stories; a past (or future) me has no more fundamental reality than Santa Claus.
