Difficult thread this…
Morality, our consciousness and all of this which is not physical but merely ideas or common knowledge is hard to put into any kind of category I think.
All of these things exist on some level, outside of the person, because many people see them the same way, and it kind of lingers in the air.
Even if they were just a sum of physical parts in the brain, then that brain has another level somewhere, where it experiences something.
I notice you haven’t brought the human mind much into this, but I think it is very metaphysical, and also very important to this discussion.
If the metaphysical is purely a common accepted idea that many people hold in their heads, then it’s only the materialistic parts making a cognitive decision that something exists, but it doesn’t exist outside of these brains.
It’s purely a side effect of cognitive beings(run by physical parts).
If on the other hand, there is some sort of morality particle, or any other particle that is not physical, then there might be some sort of metaphysical side to the universe which is not explored yet.
If we bring it further and say that the Supreme Being is /everything/, then this is just a classification from us, since I believe everything in the universe whether it be metaphysical or physical, has zero value, it’s just a complex pattern of one dimensional pieces.
Either way, I’m stuck with the notion that I have no clue, which is true, i have too little information on both quantum mechanics and the metaphysical to make a judgement like this.
