Well, that's an interesting definition, although 'm not entirely sure what it means.
Do you think, perhaps, that consciousness bypasses the thinking mind?
It doesn't appear to calculate. Nor maneuver for advantage, the way the mind does.
Why are mind and consciousness considered separate? That's like claiming no connection between cars and driving. Well sure, chariots can be driven too I suppose.
I think this is best modeled on a gradient or spectrum like the electromagnetic one. If it has a nervous system, it can be found in our spectrum. Not all lifeforms qualify because not all have nervous systems per se; some, like microbes, utilize simpler chemical exchanges without the neural substrate medium which is insulated from the external environment because of problems in scale.
Not everything that exhibits what can be broadly measured as a behavioural or effect pattern is even a lifeform; see pseudo lifeforms like viruses, or inorganic effects like weather and cosmological processes.
Little behaviour is actual consciousness. Some behavioural commands transmitted over a nervous system are autonomic, for system maintenance. So what distinguishes consciousness from lack of it? Self-awareness, for which consciousness I consider to be a needless euphemism.
Self-awareness is the state in which a lifeform is capable of making a distinction between that which is itself and the rest of its environs.
So, returning to our spectrum model, I would place our own human consciousness (a deliberately vague term), in the visible light region, for most of us neslted up near the ultraviolet. Let's approximately map some sample critters:
** we are unable to operate at this level **
Inert matter: nothing
Earthworm: far infrared
** basic self-aware, we begin to "see" here **
Garden lizard: near infrared to VL
Equine/bovine/retard: middle visible light
** advanced self-aware **
Simian/human: VL closer to UV
Genius: VL to near UV region
** nobody can "see" past here **
Advanced other/unknown/alien: UV? x-ray? parallel VL in a 3D spectrum model?
