The Self Across Time
Am I even the same person I was — and who am I saving for?
The question
You and your sister both remember the day the dog died. You remember holding it. She remembers that you weren't even there — you were at camp, she called you after. You've told your version for twenty years. One of you is remembering something that didn't happen, and from the inside, there is no way to tell which one of you it is. Now hold that thought, because tonight you're going to do something for a person you've also never met: you're going to put money away, for thirty years, for someone who will have your name and your face and almost none of your memories — and you're going to call that person you.
The episodes
Each episode builds on the one before, and the finale hands the question back to you sharper, not settled.

Whose memory is this?
Memory feels like a recording — fixed when it was made, played back on demand. This episode tests that picture against the evidence, including Elizabeth Loftus's studies in which whole childhood episodes that never happened were planted and then sincerely defended, and finds that clarity, detail and felt certainty mark false memories as strongly as true ones. What is lost is not memory itself but the inference from "I remember it clearly" to "it happened."

You are who you remember
John Locke argued in 1694 that what makes you the same person as the child in the photograph is neither the body nor the soul but consciousness reaching back. The episode states his case in full, sets out the classic objections, and follows the modern repair by Sydney Shoemaker and David Lewis — which saves the account by replacing the single unbroken self with overlapping psychological connections, and asks what that replacement costs.

The self that tells the story
Marya Schechtman's The Constitution of Selves (1996) holds that a person constitutes themselves by organising their life into a story — an account that can carry a childhood no one remembers and a responsibility memory has lost. The episode builds the narrative view at full strength, then hears Galen Strawson's objection that some people live full and decent lives while telling no story at all. Both claims are left standing.

Are you an animal?
Eric Olson's The Human Animal (1997) argues that you are a living organism — the same animal that was once a foetus and may end as a patient who cannot think — and that being a person is a phase of that animal's life, not what you fundamentally are. The episode builds the case for animalism, including the thinking-animal argument, and states plainly what its kind of continuity costs.

The machine on Mars
Derek Parfit's teletransporter, from Reasons and Persons (1984) — a booth on Earth records and destroys a traveller, and an exact copy wakes on Mars. Parfit argues that the question "will it be me?" may be empty, and that nothing we care about was riding on the answer; defenders of a simple, further self reply that no such machine could ever reach their view. Neither side refutes the other.

The chariot
In the Questions of King Milinda, a Buddhist monk answers a Greek-descended king with the analysis of the chariot — a true and useful name for parts assembled, not the name of a further thing — and then applies it to the person, through the five aggregates. The doctrine of anātman reaches the place Parfit reached, two thousand years earlier, and offers it as medicine rather than a puzzle.

No recording, no recorder
Two findings from earlier in the series are set side by side for the first time — memory is not a recording, and no single continuous keeper of the record can be found, a result Hume also reported in his Treatise of Human Nature. The episode weighs the two honest readings of what remains, Parfit's sense of release and the colder report of others, and declines to choose between them.

A stranger with your name
The last assumption left standing is the practice of providing for one's future self, treated as simple arithmetic. Max Weber's The Protestant Ethic and the Spirit of Capitalism (1905) is used to trace where the saving, planning self came from, and the closing question is handed back — whose life are you saving for? No verdict is offered.
