That there may be a resemblance betwixt natural and artificial sounds, is self-evident; and that in fact there exist such resemblances successfully employ’d by writers of genius, is clear from the foregoing examples, and many others that might be given. But we may safely pronounce, that this natural resemblance can be carried no farther. The objects of the several senses, differ so widely from each other as to exclude any resemblance. Sound in particular, whether articulate or inarticulate, resembles not in any degree taste, smell, or motion; and as little can it resemble any internal sentiment, feeling, or emotion. But must we then agree, that nothing but natural sound can be imitated by that which is articulate? Taking imitation in its proper sense, as involving a resemblance betwixt two objects, the proposition must be admitted. And yet in many passages that are not descriptive of natural sound, every one must be sensible of a peculiar concord betwixt the sound of the words and their meaning. As there can be no doubt of the fact, what remains is, to inquire into its cause.
Resembling causes may produce effects that have no resemblance; and causes that have no resemblance may produce resembling effects. A magnificent building, for example, resembles not in any degree an heroic action; and yet the emotions they produce, being concordant, bear a resemblance to each other. We are still more sensible of this resemblance, in a song where the music is properly adjusted to the sentiment. There is no resemblance betwixt thought and sound; but there is the strongest resemblance betwixt the emotion raised by music tender and pathetic, and that raised by the complaint of an unsuccessful lover. To apply these examples to the present subject, I observe, that the sound even of a single word makes, in some instances, an impression resembling that which is made by the thing it signifies; witness the word _running_, composed of two short syllables; and more remarkably the words _rapidity_, _impetuosity_, _precipitation_. Brutal manners produce in the spectator, an emotion not unlike what is produced by a harsh and rough sound. Hence the figurative expression, _rugged_ manners; an expression peculiarly agreeable by the relation of the sound to the sense. Again, the word _little_, being pronounced with a very small aperture of the mouth, has a weak and faint sound, which makes an impression resembling that made by any diminutive object. This resemblance of effects, is still more remarkable where a number of words are connected together in a period. Words pronounced in succession make often a strong impression; and when this impression happens to accord with that made by the sense, a peculiar pleasure arises. The thought or sentiment produces one pleasant emotion: the melody or tone of the words produces another. But the chief pleasure proceeds from having these two concordant emotions combined in perfect harmony, and carried on in the mind to a full close[94]. Except in the single case where sound is described, all the examples given by critics of sense being imitated in sound, resolve into a resemblance of effects. Emotions raised by sound and signification may have a resemblance; but sound itself cannot have a resemblance to any thing but sound.
