Should scientists be materialists? According to hylomorphists, the physical world explored by the natural sciences is not reducible to one kind of material stuff of which everything else is made: the fundamental objects of scientific inquiry are compounds of both matter and form. I have been investigating the metaphysics of hylomorphism and its application to modern science, both in the philosophy of physics and the philosophy of biology.

Where do minds fit in the physical world? Modern physics is widely believed to provide an account of the world in terms of a closed system of particles or fields governed by laws which lack purpose or goals. This leaves unresolved questions concerning how the conscious and goal-directed behaviour of minded, macroscopic systems is supposed to emerge. I am exploring hylomorphic models that build goal-directedness back into the cosmos as a whole, in which macroscopic systems are ‘minded’ by participating in the mentality of the cosmic whole. I am also exploring hylomorphic models in which certain macroscopic systems have strongly emergent minds. Does the world instantiate both a cosmic and macroscopic minds?
Do quantum systems have causal powers? According to some philosophers, the world disclosed by our best physics consists fundamentally of relations rather than of things which have intrinsic properties or exercise causal powers. I have been investigating the metaphysics of causal powers and their application to different interpretations of quantum mechanics.

Do macroscopic quantum forces reduce to microscopic forces? Many of the sticky forces we experience between macroscopic bodies -- such a parking ticket and a car wind screen, for example -- as well the attractive forces that keep chemical compounds together, contain a component which has to be modelled using quantum mechanics. Some physicists think these are ultimately reducible to microscopic interactions. I have been investigating the physics of macroscopic quantum forces in nature and the metaphysics of microphysical reductionism.

A Colloquium Concerning the Nature and Reality of Middle-Sized Things
A wide-ranging three-day discussion in Oxford at different locations, including a workshop at All Souls College, in which we debated what kind of philosophy best upholds the nature and reality of 'middle-sized things' -- such as scientists and their instruments of measurement. Our discussions spanned topics in the Philosophy of Physics and the Philosophy of Mind, Metaphysics, and Science & Religion.
