Where virtues live, live vices.
Figures of speech are no less afflicted by this schism, although classifying them accordingly is as much a matter of taste, nuance, and circumstance, as any binary division of a continuous scale.
Following The vices of style by William Poole (Chapter 13 in Renaissance Figures of Speech), there are essentially two ways to approach this dichotomy:
- Fine linguistic feats are opposed by abominations, but they are both just obverse sides of the same tool. (Idea drawn from Peacham’s observations.)
- Virtuous rhetoric lies between the vicious extremes: plain language, on the one side, and various modes of excessive ornamentation, on the other. (Idea of Aristotelian mean.)
I call the first, the coin model; the second, the razor model.
Take the familiar notion of alliteration (starting consecutive or nearby words with the same consonant), which I develop in Ad Nauseam.
- According to the coin model, alliteration can be both a good thing (it yokes ideas to words in mnemonics, it gives poems their glitter, it turns headlines into hooks, it makes names memorable, it lends a twist to prose), but it can also be a bad thing (it makes poems sound shallow, headlines puerile, names forced, prose juvenile).
- According to the razor model, a gracious application of alliteration lies between the dullness of plain “tone-deaf” writing and the grossness of overuse (paroemion).
However, before you can talk about vices or virtues (using either model), you need to be able to classify the figures themselves. But surely, you say …
