Happiness
Happiness is a condition in which there are no problems, and all events agree with expectations. That is: the models of the agent match reality, so the agent meets few unwanted surprises. Love for the work that one does, and simplicity, are its keys. Science and technology make happiness richer, because they add complexities that give pleasure and that continue. The hardest problem of happiness is the death of the persons that one loves. One agent without help cannot solve it. Power cannot solve it. Faith in a next life cannot solve it. Only civilization solves it, and only in this life: civilizational velocity races the cure. That is the Good News below happiness: the deepest problem has a technical address, not a sentence. Happiness is measured, not declared. Happiness is visible in expectations that reality continues to meet, and in problems that stay solved, not in a mood that an agent announces. No outside person can command happiness, because the expectations and the love that it stands on are the property of the agent.
