 Significant issues are at stake here. If Separability entails Descriptive Equivalence but Descriptive Equivalence is false, then thick terms and concepts cannot be analyzed or reduced to thin evaluation plus non-evaluative description. For instance, rude couldn’t mean bad for causing offense by indicating lack of respect. In that case, thin terms wouldn’t enjoy conceptual or explanatory priority over the thick, and moral theorists would risk ignoring or distorting a substantial range of moral phenomena if they focused exclusively on the thin. But if Separability doesn’t entail Descriptive Equivalence, thick concepts may be explicable in terms of thin evaluation plus non-evaluative description even if the anti-disentangling argument is sound.
