The principal aim of this article is to examine the capacity of existential analytic to suggest alternatives to entrenched dichotomies and dilemmas in practice theory, and more generally, in social theory. In this regard, the doctrine of trans-subjective existentialism is developed. The underlying aim is to inform hermeneutic engagement with social practices’ potentiality-for-being in order to illuminate a possible existential ontology of practices. It is argued that the concept of chronotope should be central in this ontology. Thus, the possibility of hermeneutic realism about social practices becomes open to scrutiny.
