To expand a bit on what kpreid said:

Mitchell_Porter's second claim: "Therefore consciousness cannot be directly identified with any complex entity built up out of aggregation of parts in space." is NOT falsified by kpreid's example.

However, kpreid has given an example of a very reasonable INDIRECT identification which Mitchell Porter's argument would classify as "dualist". This example illustrates that Mitchell Porter is including far more positions underneath the umbrella of "dualism" than the ordinary "substance dualism" that, for example, Decartes espoused.
