 Kitcher’s claim that an objectivist analysis, as he puts it, is “grounded” on facts about the human body is perhaps not as clear as it might be. Before arriving at some qualifications, then, we should have straightforward statements of naturalism and constructivism in hand. (Although, since the qualifications are not yet in place, perhaps no theorist would fully endorse these bald versions of the positions.) There are also taxonomies that cut finer. Broadbent (2019, p.93) argues that naturalism and normativism are only two of the distinctions we need to inform the debate. He thinks of them as “diagonal opposites on a 2×2 matrix of possible positions, being Value-Independent Realism and Value-Dependent Anti-Realism respectively.” Broadbent also recognizes Value-Dependent Realism and his own Value-Independent Anti-Realism. Whether or not constructivist analyses should really be seen as anti-realist in a metaphysical sense is not always clear, though. For reasons outlines below, the philosophical commitments of constructivist views are sometimes hard to grasp.
