I know I often sound like a broken record, but I’d say this just keeps coming back to the fundamental uncertainty we have about the relationship between reality as it is and as we know it and the impossibility of bringing those two into perfect, provable alignment. This is further complicated by the issue of whether or not the thing we’re dealing with, moral facts, exist or, if they do exist, exist mind-independently, and question to which it so far seems we are unlikely to find a solution for unless we can find a synthesis over our existing notions of morality such that we are able to becomes deconfused about what we were previously trying to point at with the handle “moral”.
