Editorial synthesis · provisional

Definition

Irreversible harm is damage whose destruction cannot meaningfully be restored and whose effects can become lasting conditions for subsequent lives. Its plausibility imposes a threshold on the regimes and actions one may sustain, rather than merely adding another cost to an ordinary calculation. Restraint does not mean automatic abstention: inaction can also leave irreversible loss in place.

Explanation

AB makes permanent error a reason for heightened restraint, while its triage discussion recognizes that delay may deepen harm. Urgent intervention must preserve a path to repair and return to reconstruction, so that emergency measures do not become the infrastructure of ordinary governance.

RB3 distinguishes threshold emergencies from institutional design. Its trolley discussion permits bounded action to reduce irreversible loss when better options have already disappeared, but rejects making that forced choice a universal template. The AI constitution likewise retains limits against domination and captured judgment under emergency conditions.

PB states the red line and the obligation to choose with least foreclosure while retaining repair. RB2’s thermodynamic irreversibility is broader: it can be constructive as well as destructive. The physical direction of time is therefore relevant background, not a definition of every irreversible change as moral harm.

Scope and attribution

Retain the ethical threshold sense and its explicit triage qualification; no invented risk formula or universal solution is supplied.

AB — The Actual Book

A threshold of non-restorable damage requires restraint and a return from triage to reconstruction.
