The important point in Leibnitz’s philosophy is this intellectuality of representation which Leibnitz, however, did not succeed in carrying out; and for the same reason this intellectuality is at the same time infinite multiplicity, which has remained absolutely independent, because this intellectuality has not been able to obtain mastery over the One. The separation in the Notion, which proceeds as far as release from itself, or appearance in distinct independence, Leibnitz did not succeed in bringing together into unity. The harmony of these two moments, the course of mental representations and the course of things external, appearing mutually as cause and effect, is not brought by Leibnitz into relation in and for themselves; he therefore lets them fall asunder, although each is passive as regards the other. He moreover considers both of them in one unity, to be sure, but their activity is at the same time not for themselves. Every forward advance becomes therefore incomprehensible when taken by itself, because the course of the representation as through aims in itself, requires this moment of Other-Being or of passivity; and again the connection of cause and effect requires the universal: each however lacks this its other moment. The unity which according to Leibnitz is to be brought about by the pre-established harmony, namely that the determination of the will of man and the outward change harmonize, is therefore brought about by means of another, if not indeed from without, for this other is God. Before God the monads are not to be independent, but ideal and absorbed in Him.
