Quantum contains the negativity that belongs to the nature of the concept but not as in any way already posited in the determination which is specific to it; so far as the concept is concerned, the differences of quantum are superficial determinations; they are still far from being determined as they are in the concept It was in the infancy of philosophical thinking that numbers were used, as by Pythagoras, to designate universal essential differences, and for this purpose, first power, second power, etc., have no advantage over numbers.
