Derek Parfit affirmed that personal identity is not a deep further fact, and he described the discovery as liberating: the walls of the glass tunnel in which he had seemed to live disappeared. This article asks what kind of relation is left once the further fact is gone. Parfit's answer, Relation R, is a relation of preservation: it measures how much of the past is carried forward, and its stronger component, connectedness, weakens with distance.

Read moreDerek Parfit affirmed that personal identity is not a deep further fact, and he described the discovery as liberating: the walls of the glass tunnel in which he had seemed to live disappeared. This article asks what kind of relation is left once the further fact is gone. Parfit's answer, Relation R, is a relation of preservation: it measures how much of the past is carried forward, and its stronger component, connectedness, weakens with distance. I argue that this leaves out a second relation, reinterpretive depth: the extent to which later mental life has reworked earlier experience by successive inversions of its reading. The argument draws on the Systems of Reinterpretation, in which self, ego, and identity are functional systems for the recursive reinterpretation of a finite stock of experience. Variants of Parfit's own teletransportation cases show that depth is reductionist and can hold with any cause, but that it varies independently of R and of a person's narrative; this distinguishes it from narrative self-constitution. Three boundary conditions (fidelity to the record, derivation from an earlier reading, integrability into a trajectory) separate depth from fabrication, imposition, and drift. The main consequence concerns Parfit's argument that it is not irrational to care less about one's further future: the argument holds only if preservation is all that matters. Once depth is admitted, the distant future self is not a fading copy of the present one, but its reader, and what licenses a discount is the expected fate of the capacity to reinterpret, not distance. Identity is not what matters, but it is what makes what matters possible.
