A different but related question that (I feel) makes the dilemma clearer:
Is there any cause that you would be willing to be tortured for if you were assured that your memories of the torture (and all subconscious aftereffects) would be subsequently erased, but would be unwilling to be tortured for if there were no such assurance?
I don't think I understand the riddle of experience vs. memory. I would daresay that means the concept is half-baked.
Within the TED talk, Daniel Kahneman poses the probably familiar philosophical quandary: if you could take a beautiful vacation and afterwards your memory and photo album was completely erased, would you still do it? Whether you would still do it illustrates whether you live in service of the experiencing self instead of the remembering self.
Part of what prevents me from understanding the riddle is that I believe vacations are worth more than the memories and photos: vacations change you.
Maybe you could argue that this change is also a form of memory in service to the remembering self, but I'm not sure that's what he meant. In his thought experiment on vacations he asks if you would still take a vacation if, at the end of it, you forgot the whole thing and all of your photos were deleted.
