 One might combine the idea that normative facts are analyzable in terms of facts about reasons with the idea that practical reasons are essentially facts about desire satisfaction. On this basis, one might conclude that all normative facts are fundamentally facts about desire satisfaction – or informed desire satisfaction, or the like. One might then propose that the normativity of a fact consists in its being analyzable as a fact (of some relevant kind) about desire satisfaction. This then would point the way toward a naturalistic constitutive explanation of normativity. This basic strategy has been developed in detail by Mark Schroeder (2007).
