This ordering, although a mere order, a still wholly external unity, demonstrates itself to be, as the immanently specifying unity of a measure which has a determinate being for itself, distinguished from its specifications; but this specifying principle is not yet the free concept, which alone gives its differences an immanent determination; the principle is at first, rather, only a substrate, a matter, for whose differences, in order that they be totalities, that is, that they should have in themselves the nature of their stable, self equal substrate, there is only available the external quantitative determination which shows itself at the same time to be a qualitative differentiation.
