(_a_) In the _first_ place the notion is absorbed so immediately in pure objectivity, that, in its character of subjective and ideal unity, it wholly fails to assert itself, and passes over instead as a thing without a soul into the raw _materia_ presented to sense. The purely mechanical or physical bodies in their isolated singularity are of this order. A particular metal is, for example, essentially no doubt a manifold of mechanical and physical qualities; every part of it, however, has such qualities equally in itself. Such a body not merely fails to possess any entire articulation of its parts in the sense that every one of its different parts receives for itself a particular material existence, but even the negative ideal unity of such differentiation is absent, which might assert itself as animating principle[201]. The difference here is a purely abstract multiplicity, and the unity posited the indifferent equilibrium of identical qualities. This is the first mode of the existence of the notion. The differences here receive no independent existence, and the ideal unity is not found as ideality. For this reason such isolated bodies are essentially defective and abstract existences. (_b_) Natural objects of a higher order suffer the differences asserted by the notion to appear as free, so that each one as external to another is itself independently existent. Here we have for the first time the true character of objectivity. Objectivity is just this independent assertion of the segregated differences determined by the notion. On this plane of existence the notion asserts itself in such a way that it is at least a totality of its differences, which is truly realized, in so far as the particular bodies, while they each severally possess independent existence for themselves, are at the same time members of _one inclusive system._ Of such a character is the solar system. In one aspect of them the sun, comets, moon, and planets appear as independent heavenly bodies apart from one another; in another, however, they derive their definite character from being parts of one system of such material bodies. Not only their specific modes of motion, but also their physical qualities, are only to be deduced from their relation to this system. This nexus which binds them together constitutes that inward unity which relates these particular existences together in one whole.
