Accordingly ugliness in itself can be no subject for poetry. Yet Homer has described its extreme in Thersites, and described it by its coexistent parts. Why did he allow himself in the case of ugliness what he wisely refrained from as regards beauty? Will not the effect of ugliness be as much hindered by the successive enumeration of its elements, as the effect of beauty is neutralized by a similar treatment? Certainly it will, and therein lies Homer’s justification. The poet can make ugliness his theme only because it acquires through his description a less repulsive aspect, and ceases in a measure to produce the effect of ugliness. What he cannot employ by itself, he uses as an ingredient to excite and strengthen certain mixed impressions, with which he must entertain us in the absence of those purely agreeable. These mixed sensations are those of the ridiculous and the horrible. Homer makes Thersites ugly in order to make him ridiculous. Mere ugliness, however, would not have this effect. Ugliness is imperfection, and the ridiculous requires a contrast between perfections and imperfections.[149] This is the explanation of my friend, to which I would add that this contrast must not be too sharp and decided, but that the opposites must be such as admit of being blended into each other. All the ugliness of Thersites has not made the wise and virtuous Æsop ridiculous. A silly, monkish conceit sought to transfer to the writer the γέλοιον of his instructive fables by representing his person as deformed. But a misshapen body and a beautiful soul are like oil and vinegar, which, however much they may be stirred together, will always remain distinct to the taste. They give rise to no third. Each one produces its own effect,—the body distaste, the soul delight. The two emotions blend into one only when the misshapen body is at the same time frail and sickly, a hinderance and source of injury to the mind. The result, however, is not laughter, but compassion; and the object, which before we had simply respected, now excites our interest. The frail, misshapen Pope must have been more interesting to his friends than the strong, handsome Wycherley.
