Humanity's Morality
I understand. My point is that this isn't useful. The axioms are just statistics. One can do away with them and just tell people the statistics and have a single moral imperative: conform! — Kenosha Kid
If the statistics are represented as axioms they can be used to theoretically develop abstract rules via rational discourse. This would allow for growth and progress. Furthermore, these abstract rules would be able to be applied in different situations; it would be impossible to have a referendum, and thus statistic, on every possible situation. So, in some ways one would have to conform; but in a situation that doesn't correlate to a specific statistic one would have to apply multiple consensus-defined axioms to come to the right act. If there was a single moral imperative based on the statistics this would be impossible.
through rational discourse one could persuade people to act in new ways via application of axioms that are established by consensus
— Aleph Numbers
But wouldn't those persuaders and persuadees be acting against morality by arguing against moral truths? If majority opinion is moral fact, then contrary opinion is also contrary to morality. — Kenosha Kid
This is only partially true.
Acting counter to what is believed to be good behavior would be wrong, but to argue that the consensus is wrong could be considered not immoral. For example: if the majority of humanity believes that stealing is usually a wrong behavior for most people some of the time, a descriptive claim, is run through the process I outline in the OP, it becomes the moral axiom that stealing is sometimes justified relative to humanity. This is because the morality I propose is defined as "what is considered by the majority of humans to be good or bad behavior for most people some of the time" One can make another descriptive claim, such as that stealing is a good behavior if you are trying to feed your starving children, that isn't by definition immoral as it is merely descriptive until it is run through the consensus finding process. Nor is it by definition incorrect; but if the initial statistic were that stealing is always a wrong behavior for most people some of the time it would result in the axiom that stealing is always wrong relative to humanity, and, thus, to propose a descriptive claim that would result in a contradictory axiom would indeed be immoral. But one could still argue that a certain moral belief is more or less rational given what axioms are currently defined by the consensus.
