Somebody saying ‘this is so’ doesn’t make it so. Whether it’s God or Dear Leader or the guy wearing the headress next to the sacrificial alter. It isn’t objective because they say so.
If they’re the head of the college of cardinals in unison with that college, or the head of the priests of the jaguar in unison with those priests, or the head of the politburo with the rest of their party at their back-
-oh yes it does. You can run afoul of it, but before the relatively novel separation of church and state, your decision would turn out very bad for you and you’d be remembered as an amoral boogeyman.
Someone else’s god or leader or the next in line to wear the feathers might determine otherwise.
If it was that fluid, you’d probably be right. But it’s not and I kinda think you know that.
It’s like papal infallibility. It becomes more damaged every time a Pope actually invokes it. It’s only pristine as an idea, not an actual practice.
What we individually determine is whether any of those guys have got it right - as far as we are concerned. And we are back to the three options.
And, for good or bad, your claim is defeated by the reasonable suggestion of “why should I give one flip about what you think”.
Functionally, morality is not an individual concept. It’s a social concept. It governs how we play with others, not how we play by ourselves.
Put it this way: If there IS an objective morality then someone has to declare it (THIS is right and THAT is wrong). And what do all honest people do at that point? They make a decision as to whether that declaration itself is right or wrong.
No, whether it’s right or wrong has been decided. You just have to decide if you submit to rules of your society. If you don’t, you get spat out by it.
Otherwise the only other choice is: ‘It must be right because the guy wearing the feathers says so’.
That’s it. The guy wearing the feathers is much more than a guy. He’s the just the latest vessel carrying the will of God.
If you didn’t like the rules of Aztec society as an Aztec, brace yourself for some hardship.
