“…To wit, failure to appreciate the distinction between Dorian Gray and Sibyl Vane-style realism does not merely compromise the realist endeavour to develop a coherent alternative to moralism, but also renders the realist challenge less pellucid than assumed. To be sure, realists advance several criticisms of political philosophy (see Galston 2010, Philp 2012, Rossi and Sleat 2014, Hall 2015, Vogler and Tillyris 2019, Geuss, 2020), and it is not our intention to elaborate on all of these here. We wish to illustrate, however, how imprecision about reality muddies the waters of a prominent realist objection to moralism – an objection which is thought to be constitutive of the realist turn: the tendency of philosophers to articulate hopeful, abstract and monistic visions of perfection under the aegis of rational harmony; comprehensive, all-inclusive conceptions of the good and/or justice, captured by a set of substantive ideals upon which rational agents can ascend.…”
