Ok, so you want to solve the "hard problem" right at the beginning by taking conscious thoughts as the basic elements of your ontology. Then they could be something like Bertrand Russell's neutral monads. If you string them into sequences according to a viewpoint the sequence constitutes a person's stream of consciousness. If you note that some such viewpoints see the same thing from different pespectives (intersubjective agreement), you create a model of external space which explains the different viewpoints. I think Russell supposed that monads corresponded to all actual events. But you could suppose that all possible (logically consistent) monads exist and then try to solve the white rabbit problem, why do some things happen and others don't (at least apparently). > The term consciousness carries so much freight that I'd prefer some > more neutral expression such as primitive self-availability, but as > you've said, non-standard vocabulary carries its own burden.
