My main research interests are in epistemology and metaphysics, philosophy of mind and action, philosophy of art, and the philosophy of Wittgenstein. In my most recent book, Action, Knowledge, and Will, I argue that human behaviour has four irreducibly different dimensions—physical, psychological, intellectual, and ethical—which were amalgamated or confused in the traditional idea of a ‘will’. My work in philosophy of art has focused mainly on the visual arts. My book The Objective Eye is about the nature of colours and shapes, their representation in pictorial art, and the concept of realism in art theory. I have also written about art and neuroscience.
