Gary Hatfield received the PhD from the University of Wisconsin--Madison in 1979,
then taught at Harvard and Johns Hopkins before coming to Penn in 1987.
He works in the history of modern philosophy, the philosophy of psychology, theories of vision, and the philosophy of science.  In 1990, he published The Natural and the Normative: Theories of Spatial Perception from Kant to Helmholtz; at HOPOS 2016, the 25th anniversary of the book was celebrated. In 2009, Perception and Cognition: Essays in the Philosophy of Psychology appeared from the Clarendon Press; a revised version of his book on Descartes' Meditations appeared in 2014.  In 2012, an edited volume (co-edited with the psychologist Sarah Allred) arising from an IRCS workshop on the constancies was published by Oxford: Visual Experience.  The revised edition of his translation of Kant's Prolegomena to Any Future Metaphysics appeared in 2004.  He is affiliated with the Center for Cognitive Neuroscience and the Penn Center for Neuroaesthetics, as well as the Visual Studies Program.  He has directed dissertations in history of philosophy, philosophy of psychology, and philosophy and history of science, and has advised several postdocs in these fields.  He has long been fascinated by visual perception and the mind–body problem.  For further information, consult Curriculum Vitae (selected [html] or full [pdf]) and research statement.

Courses a picture appears here

Fall 2018
Phil 423, Philosophy and Visual Perception
The course is divided into three units. The first is color perception, which is a microcosm of issues. We will consider color phenomenology, evolution, epistemology, and metaphysics. What is color? How do we perceive it? How do we experience it? The second unit concerns theories of spatial perception, object perception, and perceptual realisms. We will start from theories of perception in psychology and cognitive science, and then move into question of phenomenology, perceptual constancy, and the implications for perceptual realisms. The third unit concerns how visual scenes are experienced by means of images and it assesses the representational relation between images and things imaged, including linear perspective and its status as arbitrary convention or optically and naturally based system.
Readings from authors such as David Hilbert, Stephen Palmer, James Gibson, Bertrand Russell, John Searle, Nelson Goodman, and Richard Wollheim.
