It has also been claimed that constructivist theories in metaethics have an advantage over realist theories in that the former but not the latter can provide such a grounding. This paper has two goals. First, it attempts to show that constructivism does not in fact provide a complete grounding for morality, and so is on a par with realism in this respect. Second, it explains why…Read more
