John Morrison is an associate professor of philosophy at Barnard College. He is also an affiliate of Columbia University’s Zuckerman Institute and a member of its Center for Theoretical Neuroscience. John Morrison is currently working on two projects. The first is about the best way to understand the brain. In particular, he would like to identify general principles for attributing representations and inferences to it, especially when those representations and inferences involve probabilities. The second project is about the foundations of Spinoza's metaphysics. He hopes to unravel Spinoza's claims about minds, bodies, God, and their essences.
