Figure 2. A Dualist model of the causal sequence in visual perception. Light rays from a cat (as-perceived by an Experimenter) impinge on the Subject’s eye. Impulses travelling up the optic nerve produce a neural representation of the cat within S’s central nervous system. CNS activity, in turn, has a causal influence on S’s mind, resulting in a percept of a cat. It is central to this model that the percept (of a cat) in the mind of S is quite separate both from the neural representation (of a cat) in S’s brain and the cat (as-perceived by E) out-there in the world.

Figure 3. A Reductionist model of the causal sequence in visual perception. Light rays from a cat (as-perceived by an Experimenter) impinge on the subjects eye. Impulses travelling up the optic nerve produce a neural representation of the cat within S’s central nervous system. This CNS activity is subjectively experienced as a percept of a cat (in the mind of S) but neurophysiological discoveries will show this subjective experience to be nothing more than a state of or function of S’s brain.

Figure 4. A Reflexive model of the causal sequence in visual perception. Light rays from a cat (as-perceived by an Experimenter) impinge on the Subject�s eye. Impulses travelling up the central nervous system produce a neural representation of the cat within S’s central nervous system. Information within this neural representation is incorporated within an ‘experiential model’ of the cat produced by the brain in the form of a cat as-perceived by S. This is ‘projected’ by the brain to the judged location of the initiating stimulus, out-there in the world. As in the Dualist and Reductionist models the the neural representation of a cat in S’s brain is separate from the cat (as-perceived by E) out there in the world. Contrary to these models, however, S’s percept of a cat and the cat as-perceived (by S) are one and the same. Indeed what S experiences is similar to what E experiences, viz. a cat out there in the world, but viewed from S’s perspective rather than from the perspective of E.
