 On sense-datum theories, one perceives external objects and their qualities indirectly by directly perceiving (being aware of, or acquainted with) sense-data internal to one’s consciousness that resemble in various degrees the physical objects that cause them. According to sense-datum theorists, however, we are rarely, if ever, aware of this indirection in ordinary (veridical) exteroception. It is only critical philosophical reflection on features of perceptual awareness that reveals that the indirection must occur. The importance of pain and other (intransitive) bodily sensations lies in the fact that the indirection seems to be easily revealed introspectively as is shown by our unwillingness to identify the pain we attribute to body parts with anything physical in those parts.
