Both these attributes, uniformity and symmetry, being the determinations of the form and unity of external appearance, are mainly applicable to distinctions in size. For it stands to reason that what is expressly posited as external rather than truly immanent determination is generally a quantitative[242] determination, whereas the qualitative fixes the inherent character of anything. Consequently that which is assumed only to affect the external appearance cannot be concerned with the changes which are found in the qualitative aspect. Size, on the other hand, and its alteration regarded merely as size, is for the qualitative determination, when it is unable to assert itself in terms of measure, an indifferent determination. That is to say, measure is quantity, precisely in so far as it can give to itself an aspect which qualifies it, and thereby a qualitative determination is united to the purely quantitative one. As thus explained[243] uniformity and symmetry are merely restricted to the determinations of size and their uniform appearance or arrangement of differences in symmetrical order. Further inquiry will show us that this due co-ordination of size is as applicable to the forms of organic life as it is to those of inorganic Nature. The human organism is, for example, at least in a certain degree both uniform and symmetrical. We have two eyes, two arms, two legs, similar hip-joints, shoulder-blades, and so on. Of other portions of the body the reverse is the case. We find no conspicuous uniformity in the heart, lungs, bowels, or liver. The question arises what precisely constitutes the difference here. The side on which uniformity, whether of size, form, or position mainly asserts itself, is obviously the aspect of the organism viewed from the outside. The uniform and symmetrical determination, in complete conformity with what we should expect, is most apparent where the fact as objectively determined is itself the external envisagement itself, and carries with it the least impression of inherent life. The reality, which is most constant to this pure externality, rests satisfied with the abstract unity congenial to it. Within the organism, on the contrary, where we find the heart of the life-process, and still more openly in the medium of untrammelled reason uniformity gives way before the subjective unity of life. Nature is, no doubt, in its opposition to mind, a determinate existence external and independent; but even in her we find that uniformity only pre-eminently asserts itself where externality is the predominant principle.
(α) Reviewing, then, shortly the prominent classifications of natural objects, we observe, in the first place, that minerals, taking the crystal for an example, as structures destitute of the principle of life, are characterized in their fundamental form by uniformity and symmetry. As already remarked, their form, it is true, is one appropriate to themselves, is not merely the determination of external forces. Through an unseen energy the form that makes them what they are as products of Nature creates their configuration both within and without. This activity, however, is not yet the completed energy of the concrete notion as an ideal principle, which directs the independent consistency of the positive reality, subsuming them under an ideal totality such as is present in animal life. The unity and definition of their form persists in purely abstract one-sidedness, and we have as the characteristics of a unity which is wholly on the outside the bare forms of uniformity and symmetry, the determinating factor in each case being an abstraction.
(β) Plant life is, of course, many degrees above the order of crystals. From the very commencement its evolution is marked by a harmonious articulation, and consumes material in a constantly active process of self-nourishment. But plant-life also is not yet really the living whole[244]. Although organically divided into parts, its activity is still one that consists wholly in assimilation[245]. It is rooted in the earth with no independent power of motion from place to place; its growth is continuous, and such energy of assimilation and self-nourishment as it possesses is not the tranquil self-subsistence of a completely individualized organic existence, but rather a continuous extension of its growth as an external object. An animal grows just as a plant grows, but at a determinate point that growth in its external size ceases, and that which reproduces itself in self-subsistence is one and the same individual. Plant-life, however, enlarges without intermission, and only its decease renders the further increase of its boughs and leaves impossible. And, moreover, all that it separately produces in this process is for ever the repeated pattern of the same organism in its entirety. For every bough is a new plant, and not, as in the case with the animal organism, only an isolated member. On account of this persistent enlargement of itself through all the separate plant formations whereof it consists plant-life is without the subjective animation peculiar to sensation and the ideal unity which belongs to it. And, generally speaking, we may say that plant-life, however much the digestive process is an inward one, in which we find nourishment is assimilated and the organism determines the form which is impressed on its substance out of itself by virtue of the increasing freedom of the notional type working through that substance, nevertheless substantially, through the entire process of its life, it remains rooted to externality without either a true independence or unity, and such self-subsistence as it possesses is continuous without a break. And it is on account of this characteristic of plant-growth, namely, that it is for ever asserted on the side of externality, that we find uniformity and symmetry to be the fundamental unity of its self-expression as it is a predominant principle of its structure. No doubt uniformity is not so regnant here as we observed it to be in the formation of minerals, and it is not expressed in the same extreme degree through the abstract straight line and right angle: but it prevails here notwithstanding. The stem for the most part runs on a straight line; the rings of plants of higher type form themselves in circles; leaves closely approach the configuration of crystals; and, at least as the basis of their type, we find that the blossoms themselves in the number of their leaves, their position and form are determined with uniformity and symmetry.
(γ) Finally, in the living organism of animals a difference is asserted in the reduplicated structure of the members. In the bodies of animals, more particularly if we examine the higher species, the organism is a more inward, self-contained and self-determined totality; like a sphere, it returns, so to speak, on itself, while still remaining an external organism. It is an external process, and yet, as a process, asserted against externality. The more important organs are those within, such as heart, lungs, and liver, and in these the life is bound up. Such are not determined under the simple characteristics of uniformity. In those members, however, even of the animal organism, which are fixed in direct relation to the outside world, symmetrical arrangement prevails. Among such must be reckoned the members and organs which assert the subjective principle externally no less than those which are the instruments of the active life. The sense-organs, such as sight and hearing, belong to the former; all that we see and hear is left as we found it. The organs of smell and taste already mark the point of union with an activity exercised externally. We only smell that which is already assimilated[246] by the organ of sense, and we only exercise our taste through an act of destruction. We have, it is true, but one nose, but it is subdivided into two sections, each of which is uniform in structure. The same description is applicable to the lips and teeth and other organs like them. Further than this the eyes and ears, and the limbs employed in motion from place to place, or for direct control over external objects, in other words, legs and arms, are entirely uniform in position, form, and other qualities. We find, therefore, that in the organic world no less than in the inorganic uniformity asserts a very real predominance, qualified, however, by the fact that its presence is limited to those members which are the instruments of the organism in its direct relation to the external world. On those through which the life-process returns on itself by virtue of its own subjective principle there is no such impression of uniformity.
Such, then, are the leading characteristics of the forms of uniformity and symmetry, and the manner in which they are asserted in the configuration of natural phenomena.
(b) Conformity to Rule
We now propose to distinguish the more generic conception of conformity to law[247], so far as it appears on a higher plane of organic evolution than that already adverted to, and marks the passage of the same to the freedom of natural no less than spiritual life, from the more abstract forms discussed above. Taken by itself, no doubt, conformity to rule is not alone sufficient to give us the subjective unity and freedom of totality; but we do find in the configuration to which it corresponds a totality of essentially distinguished characteristics, such as do not merely emerge in difference and opposition, but betray both unity and determinate connection in such totality. A unity thus controlled, albeit still only positively asserted in quantitative substance, is no longer referable to essentially exterior distinctions of mere size numerically ascertainable, but already introduces to our notice a qualitative relation of consistency between these contrasted determinations. In other words we have here neither the abstract repetition of one and the same determinant[248], nor a uniform interchange of similarity and dissimilarity[249], but the contemporaneous association of aspects essentially distinct from one another. We find, in fact, our sense of sight gratified by the association of these distinguishing features in their completeness. And it is the principle of reason which affords us such satisfaction, gratifying our sense only through the totality, or rather through the very totality of differences the nature of the fact requires. Such a connection, however, still remains an unexplained nexus, which sense-perception arrives at partly on account of its persistent repetition, and in part through an intuition of deeper source.
A few examples will make clear the process of definition from uniformity to conformity with law. Parallel lines of equal length are abstractly uniform. A further step is taken when we compare geometrical figures of the same form, triangles, for example, but assume their size to be unequal. Here the angles subtended by the corners of each and the relation of line to line is the same, but we find such similarity in different quanta. Take again the circle, it does not possess the uniformity of the straight line, but at the same time the determination of abstract equality strictly applies to it, for all its radii are of equal length. The circle is consequently still but a curved line that awakes no particular interest[250].
On the other hand, there is still less uniformity in the ellipse and the parabola, and they are only understood through the law of their form. In other words the radii vectores of the ellipse are both unequal and in conformity with rule, and the same qualification applies to the greater and lesser axis of their lines of differentiation[251]; moreover, their foci are not central as is the case with the circle. We find in these examples, therefore, a qualitative relation of difference assert itself in the law applicable to such lines and constructive of their interconnection. If, however, we divide the ellipse by means of its greater and lesser axes we obtain four equal sections; regarded as a whole, therefore, we still find the principle of uniformity paramount in this figure. Of a higher degree of freedom in its conformity to law is the oval. We know there is such a law, though mathematicians have been unable to express its formula. This figure is not an ellipse, but the higher curve differs from that below it. Still we find that even in this example of freer eccentricity in Nature, if we divide it through its greater axis, we have still two equal halves. The final expression of mere uniformity in conformity to law is shown in lines, which, as in the example of the oval, when divided through the smaller[252] axis, give us unequal sections, neither section being a mere repetition of the other. The so-called undulatory line is an example of this, in the sense Hogarth describes it as the line of beauty. Thus the inclination of the arms as they fall on either side of the human body is opposed. Here we have conformity to rule without uniformity pure and simple. Such a kind of conformity especially characterises with its variety the conformation of the nobler living organisms.
Conformity to law is, then, an attribute of substantiality, binding together both its differences and its unity; but it remains still abstract on the side of its controlling form, unable to supply individuality with the freedom of motion, or rather by virtue of that form is entirely without the higher freedom of subjectivity, and quite incapable of revealing the vitality and ideality proper to it.
