I have four main areas of research at the moment
Apophaticism: I am interested in the view, under-represented in contemporary analytic philosophy of religion, but with plenty of classical precedence, that there is an interesting sense in which we do not know what God is. My book Negative Theological and Philosophical Analysis : Only the Splendour of Light (Palgrave) explores this, and locates contemporary wariness about apophaticism in certain unexamined commitments in the philosophies of language and mind.
Philosophy of Psychiatry: I have a cluster of interests in this area. As well as working on the relationship between religion and mental health, I am developing a justification of symptom-based diagnostic categories on the basis of a naive naturalist philosophy of mind. I am also interested in philosophical questions around the theory and practice of psychotherapy.
Herbert McCabe: I'm an expert in the work of the Dominican theologian and philosopher Herbert McCabe, and have written about his doctrine of God, his christology and his political thought. More generally, I place myself in the tradition, fostered by McCabe, of reading Aquinas in the light of Wittgenstein's later work.
Logic and theism: With Fillipo Casati I am writing a book drawing parallels between responses to the so-called paradox of ineffability and to paradoxes of self-reference in logic and mathematics.
