Morality

[The Grand Nudger]

So morality is rooted in what humanity decides about how we ought to interact with each other?

OFC, it's an evaluation.  No matter what the ontological status of the object may be, the practice of the subject remains that.  Moral facts are the thing, morality is an evaluation of relationships by reference to the thing.

We decide, for example, that skullfucking our neighbors is wrong, because we observe that skullfucking our neighbors is harmful. The natural fact (in a non natural realists conception) is the empricial status of whether or not the act causes harm. The non natural fact - that harm is wrong.

In this understanding, ouir observation of the non natural fact of harms wrongness is the metric by which we compare our empirical observations of the world...and so, that something is a skullfucking isn't why it's wrong. That we decide so isn't why it's wrong. We decide so because it is so, and we observe and communicate empirical cases that express this relationship and grant credibility to our evaluation. This means that anything which includes an empirical fact of the status of harm will be morally relevant - something to pick out of the noise and look more closely at. That this process is largely subconscious isn't even remotely surprising to a non natural realist. It's exactly what would be expected of an agent like ourselves.
