The central ethical proposition of Chapter 3373: "Through it, he saw not anomalies to be purged, but stories to be witnessed." This is the chapter's thesis — the transition from the System's epistemology (anomalies = threats = purge targets) to a new epistemology (consciousnesses = stories = witness subjects). The word "purge" carries the violence of the old creed; "witness" carries the openness of whatever replaces it. Rhys doesn't yet know what to offer (the beat's open question remains), but he knows what NOT to offer: he will not hunt. The threshold is crossed when the choice to witness replaces the instinct to purge.
