Now, since in the judging of magnitude we have to take into account not merely the multiplicity (number of units) but also the magnitude of the unit (the measure), and since the magnitude of this unit in turn always requires something else as its measure and as the standard of its comparison, and so on, we see that the computation of the magnitude of phenomena is, in all cases, utterly incapable of affording us any absolute concept of a magnitude, and can, instead, only afford one that is always based on comparison.
