Soul, says Hegel, is not a separate and additional something over and above the rest of nature: it is rather nature’s “’universal immaterialism, and simple ideal life(77).” There were ancient philosophers who spoke of the soul as a self-adjusting number,—as a harmony, or equilibrium(78)—and the moderns have added considerably to the list of these analogical definitions. As definitions they obviously fall short. Yet these things give, as it were, by anticipation, an image of soul, as the “ideality,” which reduces the manifold to unity. The adhesions and cohesions of matter, its gravitating attractions, its chemical affinities and electrical polarities, the intricate out-and-in of organic structure, are all preludes to the true incorporating unity which is the ever-immanent supersession of the endless self-externalism and successionalism of physical reality. But in sentiency, feeling, or sensibility, the unity which all of these imply without reaching, is explicitly present. It is implicitly an all-embracing unity: an infinite,—which has no doors and no windows, for the good reason that it needs none, because it has nothing outside it, because it “expresses” and “envelopes” (however confusedly at first) the whole universe. Thus, even if, with localising phraseology, we may describe mind, where it _appears_ emerging in the natural world, as a mere feeble and incidental outburst,—a rebellion breaking out as in some petty province or isolated region against the great law of the physical realm—we are in so speaking taking only an external standpoint. But with the rise of mind in nature the bond of externalism is implicitly overcome. To it, and where it really is, there is nothing outside, nothing transcendent. Everything which is said to be outside mind is only outside a localised and limited mind—outside a mind which is imperfectly and abstractly realised—not outside mind absolutely. Mind is the absolute negation of externality: not a mere relative negative, as the organism may be biologically described as inner in respect of the environment. To accomplish this negation in actuality, to bring the multiplicity and externality of things into the unity and identity of one Idea, is the process of development of mind from animal sensibility to philosophic knowledge, from appetite to art,—the process of culture through the social state under the influence of religion.
