John Morrison


I am an assistant professor of philosophy at Barnard College, Columbia University. I received my PhD from NYU in 2009.


My research is primarily in the philosophy of mind and the history of modern philosophy (esp. the seventeenth century). I also have strong secondary interests in metaphysics, medieval philosophy, philosophy of language, and logic.

I am currently working on two projects. The first is about the way we visually represent colors, locations, and durations. It draws heavily on empirical psychology, particularly psychophysics and cognitive psychology. As part of this project, Josh New and I are experimentally testing the link between cognitive speed and one's sense of time's passage. The second project is about the foundations of Spinoza's metaphysics. I hope to improve our understanding of his three basic, undefined relations: causation, conception, and inherence. I hope to use this to better understand his view of God and finite things, particularly their essences.
