Morality is as absolute as mathematics. Everything else is not morality but competitive strategy: contractual variations upon objective morality. Just as all law is as absolute as mathematics but all legislation contractual variation (or command).
The conflation of morality with strategy, and law with command is a long-standing problem in rational philosophy.
The law and morality are identical in content. Group Strategy and Group Contract are merely utilitarian.
Cooperation evolved after individual survival. For cooperation to be rational it must be mutually beneficial. For it to be mutually beneficial it must be (in the aggregate) non-parasitic.
We raise our children, demonstrate kin selection with kin, and we cooperate with non-kin, and we compete with those with whom we do not cooperate.
So:
Productive
Fully informed.
Warrantied.
Voluntary Transfer
Free of Negative Externality of the same criteria
equals
beneficial cooperation.
Morality is an absolute. Norms are merely tactics.
Legislation is not necessarily lawful. Norms are not necessarily moral.
As such, we can measure whether some cultures are more moral than others, by measuring the degree of suppression of parasitism (free riding) that is suppressed by law and norm.
So not only is morality absolute, but the relative moral content of different cultures is absolute.
That this difference determines economic velocity, and economic velocity affords us greater morality (if we choose it) is the more interesting area of inquiry.
