One criterion of an adequate analysis of the nature of consciousness has to do with its three parts, sides or elements. These are seeing and the like, thinking and the like, and desiring and the like. The seeming natures of the perceptual, reflective and affective parts or whatever of consciousness are different despite similarity. An adequate analysis of consciousness, even if general, will preserve the differences. It will pass the test of what you can call differential phenomenology.

Many debates about consciousness appear to be endless, in part because of conceptual confusions preventing clarity as to what the issues are and what does or does not count as evidence. This makes it hard to decide what should go into a machine if it is to be described as 'conscious'. Thus, triumphant demonstrations by some AI developers may be regarded by others as proving nothing of interest because the system does not satisfy *their* definitions or requirements specifications.

Consider three answers to the question of what it actually is for you to be aware of the room you are in. It is for the room in a way to exist. It is for there to be only physical activity in your head, however additionally described. It is for there to be non-spatial facts somehow in your head. The first theory, unlike the other two, satisfies five criteria for an adequate account of consciousness itself. The criteria have to do (...) with the seeming nature of this consciousness, and with subjectivity, reality including non-abstractness, mind-body causation, and the differences between perceptual, reflective and affective consciousness. The theory of consciousness as existence is not open to the objection having to do with a deluded brain in a vat. The theory, as any theory of consciousness needs to, explains its own degree of failure in characterizing consciousness. It releases neuroscience and cognitive science from nervousness about consciousness, and leaves all of consciousness a subject for science. The theory is a reconstruction of our conception of consciousness. It may be that we should carry forward several theories of consciousness. But they will have to be compared in terms of truth to the five criteria for an adequate theory. (shrink)
