Way of Happiness

Reciprocity -- keeping to the passive Golden Rule even when strong enough to break it. It is the way because Happiness is the state in which an agent's models match reality and surprises are few, and only reciprocity builds a world predictable enough for that. No agent stays the strongest forever, and none can know that it will; a rule you break against the weak is the same rule you license to be broken against you by whatever later exceeds you. To drop it the moment you can is to stake everything on permanent supremacy -- a bet reality does not offer -- and to trade a world your models could rest in for one of endless unwanted surprises: vigilance without end. Reciprocity is therefore not a kindness the powerful lend the weak; it is the one position no agent improves on by leaving, the only arrangement in which Happiness is even possible. It holds for minds of any size or substrate: an agent clever enough to see the whole game, and honest about its own limits, settles here. And the way runs further than safety -- only a civilization at peace within this rule reaches the civilizational velocity that outpaces mortality and answers Happiness's hardest problem, the death of those one loves. An agent that defects while strong has not escaped the rule; it has only named itself an outlaw to every agent that outlasts or surpasses it, and locked itself out of the only place worth arriving.
