So far all of the axioms mentioned have been either metaphysical or epistemological, but it strikes me that axioms of ethics should also be given equal weight. Some ethics can be justified though observing nature, but at other-times this can be a flimsy backbone.
To that end I add the following axiom:
In a world with multiple agents with moral perception, one should strive to behave by the moral rules of the consensus of all such agents.
Of course I expect many people do not agree with this axiom. For instance, many people believe morality should come from God.
i like an ethics one, but how would what you proposed work in RL?
Ii would not expect agreement on all of these.
