Alex Byrne is Head of the Department of Linguistics and Philosophy, and Head of the Philosophy Section. His main interests are philosophy of mind (especially perception and consciousness), epistemology (especially self-knowledge), and metaphysics (especially color).
Questions examined in some recent papers and articles include whether the content of perceptual experience is rich or thin, whether there are ordinary objects, and whether sex is binary. On the philosophy of color, Alex has collaborated many times with David Hilbert of the University of Illinois at Chicago; they edited the two-volume collection Readings on Color for MIT Press, and are preparing a collection of their papers. Alex also co-edited The Norton Introduction to Philosophy, now in its second edition. His book Transparency and Self-Knowledge was published in 2018.
