If a spinning disk casts a round shadow does this shadow also spin?
When you experience the total blackness of a cave, are you seeing
in the dark? Or are you merely failing to see anything (just like
your blind companion)?
Seeing Dark Things uses visual riddles to explore our ability to
see shadows, silhouettes, and black birds--plus some things that
are only metaphorically "dark" such as holes. These dark things are
anomalies for the causal theory of perception which states that
anything we see must be a cause of what we see. This orthodoxy
successfully explains why you see the front of this page rather
than its rear. However, the causal theory has trouble explaining
how you manage to see the black letters on this page. The letters
are made visible by the light they fail to reflect rather than the
light they reflect.
Nevertheless, Roy Sorensen defends the causal theory of perception
by treating absences as causes. His fourteen chapters draw heavily
on common sense and psychology to vindicate the assumption that we
directly perceive absences.
Seeing Dark Things is philosophy for the eye. It contains
fifty-nine figures designed to prompt visual judgment. Sorensen
proceeds bottom-up from observation rather than top-down from
theory. He regards detailed analysis of absences as premature; he
hopes a future theory will refine the pictorial thinking stimulated
by the book's riddles. Just as the biologist pursues genetics with
fruit flies, the metaphysician can study absences by means of
shadows.
Shadows are metaphysical amphibians with one foot on the terra
firma of common sense and the other in the murky waters of
non-being. Sorensen portrays the causal theory ofperception's
confrontation with the shadows as a triumph against alien attack--a
victory that deepens a theory that resonates so strongly with
common sense and science. In sum, Seeing Dark Things is an
unorthodox defense of an orthodox theory.
