Consciousness is self-referential. I am conscious of a thing if, and only if, I am also conscious of being conscious of that thing.Axiom 2:
Some instance is active in that it chooses the focus of consciousness.
If both are true, then the active instance can choose to focus on its own choices, or not. Moreover, it is really not free NOT to choose. It takes that choice all the time. Of course, if it chooses not to focus on its own responsibility of choice, it can forget (for some time) about that responsibility.
a) If the active instance is seperate from consciousness, it is unconscious, and that would lead to the paradoxical conclusion that consciousness is driven by unconsciousness, and therefore not conscious.
b) If the active instance is a part of consciousness, then how can it take the decisions of, or on behalf of, the whole?
If a) and b) are wrong, the active instance is identical to consciousness: Self-referential consciousness decides about its own focus. Then, consciousness itself decides to remain unconscious about certain things.
Then the question is: How in the bloody hell does it achieve that?
