 Korsgaard points to an assumption she believes that realists and antirealists share and that constructivists reject, namely, that the primary function of concepts deployed in judgments that can be true or false is to represent things as they are, so if normative judgments are true, they must represent something real out there in the world. By contrast, constructivists think that normative concepts, which are deployed in judgments that can be true or false, have a practical function: they name solutions to practical problems, rather than represent features of reality (Korsgaard 2008: 302 ff.). For instance, the concept equity does not stand for a property; instead, it proposes a response to the practical problem of how to distribute goods. Korsgaard draws the contrast between constructivism and other metaethical theories as follows. Unlike substantive realism, which holds that moral judgments are true insofar as they represent a mind-independent normative reality, and antirealism, which denies that there are normative truths because it denies that there are normative properties, constructivists hold that practical judgments can be true or false without representing mind-independent normative facts about the world (Korsgaard 2003: 325 n 49).
