Social ontology in metaethics

This article enriches discussions about the metaphysics of normative facts with conceptual resources from social ontology that metaethics has neglected so far: the resources of Haslanger’s critical realism as social constructionism. By pointing out the viability of understanding reasons as socially constructed facts, the article shows how normative facts can be understood as features of mind-independent reality that are, however, not features of the universe independently of social practices. The move into social ontology allows us to understand normative facts as mind-independent in a more substantial sense than deflationists do, by stressing individual mind-independence, while denying collective mind-independence – the subsistence independently of established human cultures. The new position can fruitfully mediate between realism, error theory and constructivism. Finally, the metaphysical nuances provided by social ontology pave the way for novel approaches to normative change and progress – thereby indicating pathways to normative theorising that many traditional metaethical positions lack.
