Debating the a Priori

What kind of knowledge can we get just by thinking? Two of the world's leading philosophers develop radically different positions, in alternating chapters, on the status and nature of a priori knowledge. The reader is able to follow up-close how a philosophical debate evolves.

Timothy Williamson is the Wykeham Professor of Logic at the University of Oxford and a Fellow of New College Oxford. He was previously Professor of Logic and Metaphysics at the University of Edinburgh, and has also taught at Trinity College Dublin, and as a visitor at MIT, Princeton, the Australian National University, the Chinese University of Hong Kong, and elsewhere. He has published Identity and Discrimination (Wiley-Blackwell, 1990), Vagueness (Routledge, 1994), Knowledge and its Limits (Clarendon Press, 2000), The Philosophy of Philosophy (Wiley-Blackwell, 2007), Modal Logic as Metaphysics (OUP, 2013), Tetralogue: I'm Right, You're Wrong (OUP, 2015), Suppose and Tell (OUP, 2020), and many articles on logic and philosophy.
Paul A. Boghossian is Silver Professor of Philosophy at New York University and the director of the New York Institute of Philosophy. He has also taught at Michigan, Princeton, Birmingham and the Ecole Normale Superieure.
