How Far Can Physical Sciences Reach?
by Robert Schroer
To put it bluntly, Physicalism is the thesis
that everything that exists is physical. Although
Physicalism enjoys a great deal of
popularity, two widely accepted theses,
(1) the physical sciences only tell us about
the dispositional properties of the
objects they study, and
(2) dispositional properties depend upon
seem to guarantee that, under some sense of
the word, the physical sciences are fated to
give us an "incomplete" picture of what exists.
In what follows, this challenge to Physicalism
will be referred to as "the challenge
of categorical properties."
