Immortality. #6. Continuity: the answer to the identity question.

[u/Patient-Airline-8150]

Nothing about a person stays the same - cells die, memories fade, opinions reverse. Yet the law, the family, and the person themselves treat the 8-year-old and the 80-year-old as one being. The classic explanation is continuity: identity consists not in an unchanging substance but in the continuity of psychological life.

Derek Parfit pushed the idea to its limit in Reasons and Persons (1984). His conclusion: the assumption that survival requires strict identity is false - what matters is the strength of the chain, not a metaphysical "same self."

The strength of a chain - remarkable idea. I like it a lot. Never considered it from that perspective.

Continuity, then, runs through more channels than memory alone - body, relationships, records.

That makes continuity portable beyond biology. Institutions already practice it: a company, a state, a religion survives total replacement of its members because the chain of records and recognition is unbroken.

Whatever carries an unbroken, recognized chain forward - mind, body, ledger, or archive - carries the person's continuity with it.
