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 connected universe (CCU)?
There are good arguable reasons for including the CCU as part of the
self. Forgetting would then mean resetting the CCU to the last
"remembered" state. In this case we have an identity relationship
between the self and the universe it inhabits. Resetting the self is the
same as resetting the universe. No more problem or paradox associated
