 Efforts to situate constructivism in relation to realism and antirealism are complicated by the fact that there are different definitions of ‘realism’ (e.g., Sayre-McCord 2015; Joyce 2015; Miller 2014). Realists agree that (a) moral discourse is cognitivist like non-moral discourse, (b) there are moral properties, such as rightness, (c) moral properties are sometimes instantiated, and (d) moral predicates express properties. But there is a disagreement as to whether in order to be a form of realism, a theory must hold a stronger claim that (e) moral properties are mind-independent. A further division, internal to realism, concerns the commitment to naturalism, which includes the claims that (f) moral properties are like any ordinary property and have the same metaphysical status as non-moral properties, whatever that is, and that (g) moral assertions express ordinary beliefs regarding the instantiation of these properties. All constructivists share a commitment to naturalism, but reject (e), holding that the instantiation of properties depend on features of our sensibility or rational agency, rather than being mind-independent. In general, constructivism shares with both realist naturalism and antirealism broadly defined the commitment to metaphysical parsimony. This is where it differs from classical and “robust” moral realism (Enoch 2011a).
