The full measure is unknowable as knowledge itself is merely the informational measure of some relational flux. Referents' therefore are allways only partially knowable. The communicable measure occurs only through some measured redundancy. Redundancy is required to established at least one cycle of communication between linked fixations. Total communication is naught, but transformation.
Transformation is intensional change.
Intention is awareness. Intention maps intension into extension. Dreaming maps extension into intension. Physical Science tells us that all is energy. Energy is the content side of the equation.
