[Serious] The Good

[Angrboda]

It hasn't eluded philosophers until now.  Moral realism is uncontroversial in the field.

Please present a citation of such which acquits your claim. Moral realism is the consensus belief. It's explanation enjoys no such consensus as far as I know. But I'm willing to learn. I rather doubt there would be entire articles devoted to anti-realism if the consensus and clarity was as you suggest. If it was, all a philosopher would have to do to refute anti-realism is point to the relevant facts. That they do not do so suggests that there exists plenty of controversy regarding moral realism. The existence of moral anti-realism alone says that you have exaggerated the claim.

Here. Let me get the ball started.

It is worth noting that, while moral realists are united in their cognitivism and in their rejection of error theories, they disagree among themselves not only about which moral claims are actually true but about what it is about the world that makes those claims true.
