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. _(c) Harmony_
