A decent theory or analysis of consciousness will also have the recommendation of answering a clear question. It will proceed from an adequate initial clarification of a subject. The present great divergence in theories of consciousness is mainly owed to people talking about different things. Some include what others call the unconscious mind.
But there are also the criteria for a good theory. We have two already — a good theory will make consciousness different and it will make consciousness itself effective.
