(_a_) Now, first, we will observe, in directing our attention more closely to the essential nature of the notion, that it is no purely _abstract unity_ opposed to the _differences_ of _phenomenal reality_; rather, as the notion, it is already the unity that integrates those relations, and by doing so is concrete totality. The abstract conceptions such as man, the quality blueness, and their like, are not notions as such at all, but rather should be called abstract general concepts, which are only raised to the dignity of the notion, when we have demonstrated that they contain opposing factors in unity, and, in such a way, that this self-related nexus of unity constitutes their notional truth. For instance, the concept "blueness" as a colour receives such a notional value when it is grasped as the unity, and, indeed, the specific unity of light and darkness[189]. In the same way the concept "man" contains within it the opposing factors of sense, life, and reason, body and mind (spirit); but a particular man is not to be regarded as a whole consisting in some way of these two aspects of his personality placed in a relation of indifference side by side as constituents of the same. Rather, in virtue of the notion, such a whole contains these constituents in concrete and mediated[190] union. Add to this that the notion is so completely the absolute bond and unity of its differences, that independently they cease to exist, they are unable to assert the particularity, in virtue of which they might escape from such a union. For this reason the notion includes all its determining constituents in the form of its own _ideal unity_ and universality, which constitute its _subjective_ character in contradistinction from the real as the object of sense-perception. For example, gold is, as a particular object, of specific weight, definite colour, and placed in a certain relation to specific acids. Such are varied characteristics of gold, and yet are invariably found in a unified whole. The smallest speck contains them all in inseparable union. By analysis or abstraction we indeed separate them, but in their notion they are inseparably one. The inability of the differences, which the notion in its truth essentially possesses, to stand alone in their isolated self-identity is of a similar nature. A still more apposite illustration is presented by the unique concept of the self-conscious Ego in its universality. For that which we call soul, or more appositely the Ego, is the notion itself in its free existence. The Ego contains a congeries of most distinct concepts and thoughts in itself; it is a world of ideas; yet none the less this infinitely complex content, in so far as it lies within the Ego, remains without a vestige of substantiality or materiality packed within this ideal unity, as the pure and throughout fluid transparency of the Ego itself reflected to itself. And this is precisely the way in which the notion
