  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. Moral realism is not a particular substantive moral view nor does it carry a distinctive metaphysical commitment over and above the commitment that comes with thinking moral claims can be true or false and some are true. Still, much of the debate about moral realism revolves around either what it takes for claims to be true or false at all (with some arguing that moral claims do not have what it takes) or what it would take specifically for moral claims to be true (with some arguing that moral claims would require something the world does not provide).
