Moral Anti-Realism

Moral anti-realism is the metaethical position that moral claims do not describe mind-independent facts. It encompasses several distinct views: moral relativism (moral truth is relative to culture), error theory (moral claims are systematically false because moral properties do not exist), and expressivism (moral claims express attitudes rather than beliefs).\n\nThe central motivation for anti-realism is epistemological: if moral facts exist, we seem to have no reliable method for knowing them. The intuitionist's 'moral sense' appears no more trustworthy than the racist's 'racial sense.' The naturalist's reduction of moral facts to natural facts appears to eliminate normativity. Anti-realism accepts that moral discourse is real and important while denying that it tracks an independent moral reality.\n\nThe systems-theoretic challenge to anti-realism asks whether a system that must coordinate its behavior can afford to treat its coordination principles as mere preferences. If moral knowledge is produced by the network of moral reasoning, then anti-realism may understate the objectivity that networks can achieve even without mind-independent facts.\n\n
