I personally approve of people solely caring about instrumental rationality
Are you saying “I personally approve of..” is the primitive, unqualified meaning of “should”?
I don’t think it can be implemented at all
I’ve agreed with that.
“Then why care about it”.
even if you can’t do anything directly useful with unattainable truth , you can at least get a realistic idea of your limitations.
At the very least it’s part of the unqualified meaning. Moral realists mean something more by it, or at least claim to do so.
Okay. I think it’s probably not the most effective way to do this in most cases.
