Consciousness (n.) is a theater of choice, a sum of contingency entering into the world.
Consciousness (n.) is coextensive with life. It is no more limited to brains than digestion is limited to animals with stomachs.
Consciousness (n.) is distinct from the organism which it animates, although it must undergo its vicissitudes, just like a river must adopt the winding course of aa river bed, though its direction remains distinct.
Consciousness (n.) is not identical with the brain; the brain is the system of images and reaction-patterns; consciousness is the recall of images and the choice of reactions.
Consciousness (n.) is proportionate to choice, filling the interval between what is done and what might be done.
