The activity of implicit mental models is unconscious mental life. Neural machinery is describable by classical physics, but is ultimately inexplicable without recourse to modern physics. Quantum physics is the second equation. In the spirit of the maxim that rigor cleans the window through which intuition shines, the proposed theory has a third equation, a Law of Motion of Consciousness. The Law of Motion states that the rate of change of consciousness with respect to subjective time equals the difficulty of the situation.
Consciousness activates mental models for solving problems.
