I believe memory to be a false pretense for identity. Sure, it’s all that we have to define ourselves but is that a factual statement or simply an excuse? Memory is past, but the moment is now, so how wrong is it to see oneself as the sum total of their experiences?
It simply isn't true.
If you're the sum total of your experiences, put down in words who you are. Write down the sum total of all your experiences, and include a transmission of how they felt and what they looked like to you at the time, regardless of how they look to you now. Please include everything that you didn't remember, because it wasn't important at the time. And keep writing, as the writing itself is now a part of the sum total and has to be described...
There's no such thing as the sum total of all your experiences. You can't experience it, can't know it, can't think about it, can't put it down in words. You cannot sum up all your experiences. A "sum total of all that has ever happened to me" is a fuzzy concept that has no actual counterpart in reality.
