"The "I" that is now trying to formulate a response to your post is using previous thoughts and experiences of the "I' that I have always been."
so you are saying that experiences don't alter " you"?
and if the 'i ' that starts going through a process of thinking or any process, really, or any time-space whatsoever is the same as the 'i' later or earlier....and there s no change......you would be saying your 'i' is fully formed right from ....when?
