It seems that there is a lot happening in metaphysics these days. There is of course the return to Aristotle that has occurred within the resurgent field of powers ontology in the theory of causation (e.g. Ruth Groff, Ontology Revisited: Metaphysics in Social and Political Philosophy, Stephen Mumford and Rani Lill Anjum, Getting Causes from Powers). But volumes like David Oderberg's Classifying Reality and Real Essentialism make it clear that the trend is broader than this. And here too, Aristotle is making a come-back. The fundamental question for metaphysics is this: what exists in the world in which we live?
