γ. The conscious monad distinguishes itself from the naked (material) monads by the distinctness of the representation. But this is of course only an indefinite word, a formal distinction; it indicates that consciousness is the very thing that constitutes the distinction of the undistinguished, and that distinction constitutes the determination of consciousness. Leibnitz more particularly defined the distinction of man as that “he is capable of the knowledge of necessary and eternal truths,”—or that he conceives the universal on the one hand, and on the other what is connected with it; the nature and essence of self-consciousness lies in the universality of the Notions. “These eternal truths rest on two maxims; the one is that of contradiction, the other is that of sufficient reason.” The former of these is unity expressed in useless fashion as a maxim, the distinction of the undistinguishable, A = A; it is the definition of thinking, but not a maxim which could contain a truth as content, or it does not express the Notion of distinction as such. The other important principle was, on the other hand: What is not distinguished in thought is not distinguished (p. 333). “The maxim of the reason is that everything has its reason,”[260]—the particular has the universal as its essential reality. Necessary truth must have its reason in itself in such a manner that it is found by analysis, _i.e._ through that very maxim of identity. For analysis is the very favourite plan of resolving into simple ideas and principles: a resolution which annihilates their relation, and which therefore in fact forms a transition into the opposite, though it does not have the consciousness of the same, and on that account also excludes the Notion; for every opposite it lays hold of only in its identity. Sufficient reason seems to be a pleonasm; but Leibnitz understood by this aims, final causes (_causæ finales_), the difference between which and the causal nexus or the efficient cause he here brings under discussion.[261] c. The universal itself, absolute essence, which with Leibnitz is something quite different from the monads, separates itself also into two sides, namely universal Being and Being as the unity of opposites.
