Philosophers working on the ontology of mind have highlighted various distinctions that can be drawn between the ways in which different aspects of our minds fill time. Matthew Soteriou explores ways in which such distinctions can help inform philosophical accounts of sensory and cognitive aspects of consciousness. He argues that work in the ontology of mind that focuses on distinctions of temporal character has much to contribute to philosophical accounts of thephenomenology of various elements of sensory consciousness. It can inform our understanding of conscious thinking, and the form of self-conscious consciousness that we have as subjects capable ofengaging in such activity, by helping to account for and explain the respect in which agency is exercised in conscious thinking. This can illuminate the more general issue of the place and role of mental action in an account of the metaphysics of mind.
