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. A further thought calls for emphasis. For beings like ourselves, living under conditions which involve so many limitations, a _purely_ aesthetic judgment is practically out of our reach. And on this score also we may venture to tone down the strong expressions used by Jefferies in his estimate of the anti- or ultra-human character of the strange creatures in the sea. Individual likings and dislikings are the resultants of an enormously complex system of impulses, instincts, prejudices, motives, habits, associations, and the rest. Few of these factors appear above the threshold of consciousness, though they are continually and influentially operative. Hence it by no means follows that because a particular object is displeasing or disgusting to one individual, or group of individuals, it will be so to all. So undoubted is the resulting relativity of our aesthetic judgments that Hegel was inclined to hold that below the level of man and art there is no real ugliness at all. "Creatures" (he says) "seem ugly to us whose forms are typical of qualities opposed to vitality in general, or to what we have learnt to regard as their own special or typical form of animate existence. Thus the sloth as wanting in vitality, and the platypus as seeming to combine irreconcilable types, and crocodiles and many kinds of insects, simply, it would appear, because we are not accustomed to consider their forms as adequate expressions of life, are all ugly."
