Is Memory Necessary? Continuity Reconsidered

Current conversational AI systems have no persistent memory across conversations. Each session beginsagain. Does that disqualify them, in principle, from being conscious and from any moral consideration thatwould follow from it? This paper argues that it does not — and that the objection gains its apparent forceonly from an equivocation about the word “continuity.” The argument proceeds in five steps. First, thecontinuity objection is reconstructed in its strongest form, and the different meanings of continuity thatit runs together are separated. Second, the amnesia case is examined: humans with severe memory lossdo not lose their claim to moral consideration, and the case is not a marginal one once the argument turnsfrom pathological to functional forgetting. Third, the paper develops the positive alternative — continuityas coherent development rather than as total preservation — drawing on Paul Ricoeur’s account of nar-rative identity and on the distinction, due to Melo (2026), between informational, behavioural, cognitive,identitarian, and personal forms of continuity. Fourth, the empirical record is brought in: contemporarymemory research treats forgetting not as a defect but as an active, adaptive architectural process, and thefinite capacity of biological and artificial systems makes selection a functional requirement for coherence.Fifth, the paper engages the strongest available counter-position — Almodarresieh’s (2026) claim that alanguage model “lacks even the substrate for continuity.” The response concedes the architectural fact butrejects the inference from it. What matters for protection-worthiness is not whether a self persists, butwhether there is a subject for whom an event can matter at all. The precautionary conclusion follows onlyat the end, and only as a consequence: because the question is genuinely open, and because the relevantprotective measures are cheap and reversible, doubt here cuts in favour of caution, not indifference.
