I did a BSc in mathematics at the University of Natal, followed by a BA and PhD in philosophy at Cambridge. After academic posts at Reading, Macquarie, Birkbeck, and Cambridge, I joined King's College London in 1990. From 2015-21 I spent half of each year at the Graduate Center of CUNY in New York. I was President of the Mind Association in 2009 and the Aristotelian Society in 2014.

I have written widely on epistemology, metaphysics and the philosophy of science and mind. My books include: For Science in the Social Sciences (1979), Theory and Meaning  (1990), Reality and Representation (1987), Philosophical Naturalism (1992), Thinking about Consciousness (2002), Philosophical Devices (2012), Knowing the Score (2017), and The Metaphysics of Sensory Experience (2021).
