CONCEPT
Moral Remainder
Williams's term for the residue of value that survives the justification of an action — the loss that persists after the correct decision has been made and that the correctness does not dissolve. The concept the AI transition generates at a scale no framework is designed to address.
Moral remainder names the phenomenon that justified actions can nevertheless produce unjustified harm — genuine losses that persist after the calculation has been completed or the duty fulfilled. Williams's paradigmatic case: a government that must flood a village to save a city makes the correct decision, and the village is nevertheless destroyed, and the destruction is a real loss that the justification does not eliminate. Utilitarianism treats the account as settled once benefits outweigh costs. Williams insisted that the settlement is illusory — that the remainder is moral reality, not emotional residue, and that a response treating it as absorbed into the aggregate has misdescribed what happened. The AI transition generates remainder in specific forms: embodied knowledge displaced, temporal space compressed, communities thinned, habits of truthfulness eroded.
