 Both Rawls (1980) and O’Neill (1989a) present Kantian constructivism as a third option between realism and relativism (see also Korsgaard 1996a: 36). However, not all constructivists share this view. In fact, some place constructivism in the realist camp (Copp, LeBar), and others in the antirealist camp (Lenman). Scanlon sides with realism about reasons but defends a constructivist account of the nature and truth of moral judgments (Scanlon 1998, 2014, 2003b: 18). Street admits to some kind of relativism. This shows that it would be a mistake to judge constructivism’s impact in metaethics solely in terms of its contribution to the realism-antirealism debate (Korsgaard 2008: 312, 325 n. 49; Copp 2013; Engstrom 2013: 138ff).
