Invariant of consciousness supports fuzzy duplicates
One might assume that their identity is only partly influenced by their unique experiences and circumstances, and that they do have a certain nature which abstracts away from the episodic. Additionally, one might recognize how they are more similar now to other individuals than to themselves from a decade earlier. Given the relaxed constraint of identity and the high uncertainty of one’s psychology, one might buy into the idea that other people fuzzily like them might persist their identity in the future, after their bodily death. This is an ambitious rationalization of death.
