 Jonathan Dancy accepts versions of both the first and second thesis, and he accepts the second thesis in part because he accepts the first. Dancy holds that there are two types of principles: absolute and contributory. An absolute moral principle specifies a sufficient condition for the instantiation of a moral property, while a contributory moral principle specifies that a feature has an intrinsic moral valence (see entry on  Dancy’s moral particularism).  Dancy holds that neither sort of true principle exists, and thus neither sort of principle can properly play a role in moral deliberation—after all, using false moral principles could lead us to act correctly for the wrong reasons, or to act incorrectly (Dancy 2005: 3).
