Towards a theory of presence

Abstract The present paper presents a new (formal) theory of presence according to which, roughly, to be present at a place is to have a delegate located at that place. One crucial feature of the theory is that something can be present at a place without thereby being located there. The theory is then applied to several central issues in metaphysics, such as persistence through times and worlds, theories of universals, the ontology of social entities, and the nature of God.
