(_γ_) The truth is we can only, in this sphere, bring before our consciousness the entire unity of life by means of our thought and grasp of reason. In the natural world the _soul_, in its full activity, is not found; that is to say, the subjective unity, in its pure ideality, does not exist there for a self-consciousness. If, however, by means of thought, we endeavour to grasp the nature of soul-life according to its essential notion we shall find two aspects under which we may regard it; first, as the form subject to such a principle of animation; secondly, as the notion of soul for thought in all that the conception implies. Such a complete grasp of its true nature is not possible in the sensuous perception of the objects of beauty. Such must neither pass before us as thought, nor must we allow the interest of Thought as such to form a barrier of difference or opposition between itself and the vision revealed to us. We are left, then, with no alternative but to consider, under this point of view, the object as wholly presented to sense; we must assume that in the sphere of Nature a _sensuous_ perception of the natural form is our genuine mode of contemplating the beautiful. "Sense," that is the master-key[232] to the position; a word which in itself is interpreted in two opposed senses. In the first place we may indicate thereby the organs of immediate[233] perception, secondly, by the "sense of a thing" we may refer to the significance, or the element of thought and the universal within it. In this way "Sense" is related on one side to the immediate externality of existence, and on the other to its inward or essential nature. A sensuous perception of that existence in fact preserves both sides in unity, or rather in one direction so presents the aspect that is opposed to it in the immediate sense vision as to include therein both the essence and notion of the object. But for the reason that it combines these opposed determinations in unfractured unity, the notion is not presented as such to consciousness, but is rather to be dimly foreshadowed there[234]. We accept, for example, as a determinate fact the existence of three realms of Nature, which we define as that of the mineral world, that of plants, and finally that of animals; we can conclude from this, as already foreshadowed by its truth regarded as a process rising from plane to plane, that there is an inward necessity inherent in the notional articulation of its divisions, and do not confine ourselves only to the purely imaginative conception of it as a world conforming on its exterior side only to a final end. In the same way when confronted with the variety of the external presentment in each of these realms, the sense-perception surmises a controlling unity intelligible to mind, a progress subject to laws of thought, visible no less in the formation of mountain ranges than in the orderly succession of plant-life and of the animal races.
