Thanks! This is like undoing historical events. If you forget about the fact that dinosaurs ever lived on Earth and there is an alternative history that led to your existence in the multiverse, and you do the memory erasure also in sectors were dinosaurs never lived, you have some

what nonzero probability implies, you'd have a hard time showing that anything non-contradictory at all has a nonzero probability of being true. Er, I typed too quickly. I mean you'd have a hard time of showing that anything non-contradictory has zero probability. Anything that isn't

I agree with Anna. In addition, it all depends on where you define the boundary of the self. Just the brain? Brain + body? Brain + body + immediate surrounding (prescription glasses being worn, automobile being driven, binoculars or computer being used) ? Brain + body + Whole causally
