Fall 2016
Phil 423, Philosophy and Visual Perception, TR 1030AM-1200PM
This class is about what it is to see. It combines philosophical and scientific approaches. Philosophical approaches to perception have emphasized phenomenology and the relations between perceptual experience and objects. Questions include: Is seeing just having certain patterns of experiences? Or does it consist in a causal relation to objects? Scientific approaches have examined the properties of visual stimulation and the processes of vision. Questions include: Is the stimulus for vision inherently ambiguous? Are the processes of vision cognitive and inferential, or do they rely on smartly engineered systems that work in relative independence of higher cognition? The philosophical and scientific approaches have, on many occasions, interacted and informed one another, as we will notice from the outset. The course is intended to be accessible to students with a previous course in any of philosophy, psychology, or visual studies. Format is lecture and discussion. Readings from authors such as Descartes, Berkeley, Wolfgang Metzger, Eric Schwitzgebel, William Hopp, John Searle, Donald Hoffman, Roderick Chisholm, R. W. Sellars, Robert Swartz, Nelson Goodman, and Richard Wollheim, among others.
