Seeing, Doing, and Knowing is an original and comprehensive
philosophical treatment of sense perception as it is currently
investigated by cognitive neuroscientists. Its central theme is the
task-oriented specialization of sensory systems across the
biological domain. Sensory systems are automatic sorting machines;
they engage in a process of classification. Human vision sorts and
orders external objects in terms of a specialized, proprietary
scheme of categories - colours, shapes, speeds and directions of
movement, etc. This 'Sensory Classification Thesis' implies that
sensation is not a naturally caused image from which an organism
must infer the state of the world beyond; it is more like an
internal communication, a signal concerning the state of the world
issued by a sensory system, in accordance with internal
conventions, for the use of an organism's other systems. This is
why sensory states are both easily understood and persuasive.
Sensory classification schemes are purpose-built to serve the
knowledge-gathering and pragmatic needs of particular types of
organisms. They are specialized: a bee or a bird does not see
exactly what a human does. The Sensory Classification Thesis helps
clarify this specialization in perceptual content and supports a
new form of realism about the deliverances of sensation. This
'Pluralistic Realism' is based on the idea that sensory systems
coevolve with an organism's other systems; they are not simply
moulded to the external world. The last part of the book deals with
reference in vision. Cognitive scientists now believe that vision
guides the limbs by means of a subsystem that links up with the
objects of physical manipulation in ways that bypass sensory
categories. In a novel extension of this theory, Matthen argues
that 'motion-guiding vision' is integrated with sensory
classification in conscious vision. This accounts for the
quasi-demonstrative form of visual states: 'This particular object
is red', and so on. He uses this idea to cast new light on the
nature of perceptual objects, pictorial representation, and the
visual representation of space.
