"Perceptual content: an objection to externalism"
October 20, 2004, 5 PM, Department of Philosophy, CEU, Zrínyi utca 14, 4th floor, room
412.
ABSTRACT:
I start by arguing for one important difference between visual perception of shape and
that of color. Visual representation of shapes is compositional, whereas that of colors is
representationally atomic. This difference explains a few other features of visual
perception. The first is that shape is absolute whereas color is relative, even though
both shapes and colors are reasonably taken to be physical properties. The second is that
vision is revelatory with respect to shape and space but it is not revelatory with respect
to color. Finally, there is one way in which shape perception is normative, and color
perception is not. Shape percepts encode the structure of the corresponding stimuli, and
this imposes constraints on which percept can correctly track which stimulus. There is no
such constraint in color perception, due to the fact that color percepts are
representationally atomic.This picture in turn gives rise to an anti-externalist argument
about perceptual content which, in my opinion, is quite compelling.
