[Footnote 137: As an example, we may take the principle of beauty as shown in the simplest and least beautiful of the regular curves, the circular. In the circle variation in direction is combined with identity in the distance from a fixed point. There is, then, unity in diversity—a general principle, of which the circle is but an example. Nature, ever affluent in resources, varies the tameness of the circle by presenting it to the eye as a right line, an ellipse, etc., according to the point of view. Thus again illustrating the law of unity in diversity; for the knowledge that the figure is still a circle is one, while the gradations in its appearance are many.]
