John Campbell is the Willis S. and Marion Slusser Professor of Philosophy at University California, Berkeley.
His main interests are in theory of meaning, metaphysics, and philosophy of psychology. He is currently working on the question whether consciousness, and in particular sensory awareness, plays any key role in our knowledge of our surroundings. He is also working more generally on causation in psychology. His books include Past, Space and Self (1994) and Reference and Consciousness (2002).
Campbell was President of the European Society for Philosophy and Psychology 2003-2006. He has given the Whitehead Lectures at Harvard, the Carnap Lectures at Bochum, the Simon Lectures at Toronto, the Clark Lecture at Indiana and the Gramlich Lecture at Dartmouth. He was Fellow of the Center for Advanced Study in the Behavioral Sciences at Stanford in 2003-2004, a British Academy Research Reader 1995-1997, and has held Guggenheim and NEH Fellowships.
In 2017, Campell received the Jean Nicod Prize which is awarded annually by the French National Centre for Scientific Research to a leading philosopher of mind or philosophically-oriented cognitive scientist.
