We have your 'Quanta' of energy and your 'Quarks' of matter, is there a 'Q' word for the ultimate unit of consciousness? Does it permeate the Universe, or is it confined to 'complex' living things? Or do only 'people' have 'consciousness'?
We have units of measurement for stuff (matter) and action (energy) about which there can be objective agreement of observers.
Consciousness is the experience of being awake. It does not have a unit of objective measurement anymore than happiness or itchiness. Also it is subjective and can only be observed by the being experiencing.
Excellent clinical definition of consciousness with regard to the attributes of thought and cognition. I disagree with it as applied to consciousness with regard to the substratum of nothingness. This is akin to deep sleep where we are not aware of forms of cognition but instead reach a point of alert mental suspension where only subtle impressions remain.
To have a unit of measurement something does need to be clinically defined. And I used the medical definition as the most widely agreed one. In more detail it requires a sentient subject able to integrate experience at the level of the cortex (or equivalent structure for other species)--that is at the level of conscious/not conscious.
I didn't really follow what else you were trying to say. I am sure consciousness has many degrees and types of state. We are conscious more or less or many different domains of experience. But what is does not have is a unit of measurement that is objective such as the units we use for force and spatial dimension.
