In considering the substance of these strong statements, characteristic of very different types of mind, we note in the first place that two different problems are to some extent fused—that of the ugly, and that of the morally evil. Of course, it is frequently impossible to separate them; still, for purposes of analysis, the attempt should be made; especially as our present quest is aesthetic rather than ethical.

In the second place it must be remembered that the nature-mystic is by no means a nature-worshipper. His claim of kinship with nature surely implies the contrary! He knows that evil and ugliness (however interpreted) are in man, and he expects therefore to find them permeating the whole.

Confining our attention as far as may be to the aesthetic aspect of the objections raised, let us at once define and face the real issue now before us, namely, the significance for the nature-mystic of what is called "ugliness."

There are certain judgments known as aesthetic—so called because they determine the aesthetic qualities of objects. And it is agreed, with practical unanimity, that they rest much more upon feeling and intuition than upon discursive reason. To this extent they rank as genuine "mystical" modes of experience, and from this point of view have bulked largely in the systems of mystics like Plato and Plotinus. But while claiming them as mystical, it is necessary to note that they possess a characteristic which constitutes them a special class. They imply reference to a standard, or an ideal. The reference need not be made, indeed seldom is made, with any conscious apprehension of the standard; but the reference is none the less there, and a judgment results. The place of reflective reasoning process which characterises the logical judgment is filled by a peculiar thrill which accompanies a feeling of congruence or incongruence, according as the ideal is satisfied or otherwise.

It is in accord with this view of the aesthetic judgment that while, for reason, the outward form and semblance of the object is of subsidiary import, save from the point of view of abstract form and physical quality, for the aesthetic feeling or intuition it is paramount. For example, a botanist, quâ botanist, will reck little of beauty of colour, or curve, or scent—indeed at times his interest in a plant may be in inverse ratio to its beauty. But the lover of flowers, or the poet, or the artist, will fix upon such aesthetic qualities as determining his mood and judgment. Not that the reflective and the aesthetic judgments are antagonistic—they are supplementary, and, when rightly appreciated, they are interdependent; nevertheless, they must not be confused.

The doctrine of Plotinus, the prince of mystics, is very helpful when the problem of the ugly is in debate, and fits in admirably with the considerations just advanced. His theory was that material objects are beautiful in proportion as they share in reason and form. The converse of this proposition is, that objects are ugly in proportion as they lack the capacity for sharing in reason and form. Passing over certain other phases of his doctrine, let us see how far this theory will carry us in answering the question—Is there in nature such a thing as ugliness, in any absolute sense of the term?

Matter, as known to the modern scientist, is universally possessed of form of some kind, and is, moreover, found to share in reason, when tested by its responsiveness, so to speak, to the processes of human ratiocination—or, in other words, by its obedience to natural law. It would seem to follow that there is no object in nature which is absolutely ugly. And the conclusion surely commends itself to common sense. If, in spite of this, certain objects are called "ugly," what is intended? Following up the lead of Plotinus, we seem to be driven to the conception of "degrees of beauty"—of "higher" and "lower" forms of beauty. And the moment the existence of such "degrees" is accepted, the aesthetic horizon is indefinitely extended. The whole problem assumes larger and more generous proportions, especially when viewed in the light of the evolution hypothesis. For where there are degrees, or stages, it is an easy step to conceive of transition from stage to stage. An ugly object is only relatively ugly; and by entering into new relations with its environment may be raised to even higher rank in the aesthetic scale of values. In brief, true progress becomes possible for the whole universe. Herbert Spencer stopped short at progress from the homogeneous to the heterogeneous. It is more interesting, not to say, inspiring, to postulate increase of capacity for sharing in reason and form. The vast process of evolution may then be viewed as an upward sweep into fuller beauty and into correspondingly fuller life.

Of the fact that there is such an upward process, there is abundant and accumulating evidence. The struggle upwards of organic life, culminating so far, in man as we know him—the increasingly complex beauty of natural forms—the haste of nature to conceal her scars—all alike speak of a striving upward. Nay, we are being told that the atoms themselves, so long regarded as ultimates, have been subjected to the evolutionary stress and strain, and have advanced from the simplest forms to higher and more complex symmetries. And in another field, the arts, more particularly painting and the drama, almost demand the recognition of some such principle of progress; for they are constantly and necessarily using elements which in themselves are accounted ugly, for the production of their supremest beauties.

The use of discords in music is singularly suggestive in this regard. There are combinations of musical sounds which, when produced as isolated combinations, are harsh, and even painful. But let them be heralded by other chords, and let them be parted from by suitable resolutions, and they can charm, or thrill, or kindle deep emotion. What does this fact imply? That discords in music, when used with knowledge and mastery, do not take their places as aliens in musical progressions—as insertions of ugliness in a texture of surrounding beauty—but as themselves beautiful. Their aesthetic value is gained by their being linked up in a network of relations which makes them part and parcel of that which is an ordered and rational whole. In short, discords are potential beauties; they have capacity for form and reason.

The ugly, then, is not to be opposed to the beautiful as its contrary, but as standing in the relation to it of the less to the more perfect. There will thus be grades of beauty as there are grades of reality. And mystic intuition will have corresponding grades of dignity and insight. The grand process of evolution is thus revealed as a many-sided whole—the amount of real existence increases in proportion to the increase of capacity for sharing in form and reason; and along with this goes a growth in power to appreciate the ever higher forms of beauty which emerge in the upward-striving universe.
