ABSTRACT OBJECTS (THAT EVEN A NATURALIST COULD LOVE)

To give a naturalized account of such claims as "Mental state S is
about object x", "Mental state S represents the property
F", and "Mental state S has the content that p", there
are two tasks that have to be accomplished: (1) give a natural account of
the relations about, represents, and has the content, and (2) give a
natural account of the entities x, F, and p. The
latter is not so easy to do when x doesn't exist or is abstract,
when F is a property which is complex or has no instances, or when
p is a proposition or state of affairs which is complex or is
(necessarily) false.
In this paper, I focus on the second task involved in naturalizing the mind
and propose that the way to naturalize the problematic entities is by way
of a new interpretation of the formal principles which assert their
existence. These formal principles are comprehension principles which
assert the existence of abstract objects corresponding to certain
expressible conditions in a formal language. If we reinterpret the
principles as asserting the existence of patterns of properties (i.e.,
conceive of abstract objects as patterns of properties), then a path opens
up to the naturalization of abstract objects. I travel down this path and
explore its consequences. The most interesting consequence is that a
certain Wittgensteinian view of meaning becomes wedded to some formal
metaphysical machinery. The result is that the former is made more precise
and the latter is made acceptable to the naturalist.
