There was another thing that really caught my eye in Baars and McGovern, Cognitive views of consciousness: What are the facts? How can we explain them? (here) They give a list of metaphors that have been used over the years for consciousness.
1. The Threshold Metaphor a stimulus above a certain value automatically enters consciousness.
2. The Tip-of-the-Iceberg Metaphor consciousness emerges from the bulk of unconscious processes.
3. The Novelty Metaphor consciousness is concerned with what is new or unexpected.
4. The integration Metaphor sensory data is passes from low-level processes to higher-level ones and consciousness is the highest and most integration perceptions.
5. The Executive Metaphor consciousness produces the self that is controlling.
6. The Searchlight Metaphor the focus of attention is basic to consciousness.
7. The Theater in the Society of Mind Metaphor access by all parts of the brain to shared information is the function of consciousness.
All of these metaphors have more than a large grain the truth to them, or they would not have lasted so long. But they also each have gaps and problems.
What I noticed, of course, was that my favorite metaphor was missing.
8. The Working Model Metaphor consciousness is the best-fit scenario of the information available to the brain to model reality.
