There is little if any hope that euphemisms will ever be excised from mankind's endless struggle with words that, as T. S. Eliot lamented, bend, break and crack under pressure. For one thing, certain kinds of everyday euphemisms have proved their psychological necessity. The uncertain morale of an awkward teen-ager may be momentarily buoyed if he thinks of himself as being afflicted by facial "blemishes" rather than "pimples." The label "For motion discomfort" that airlines place on paper containers undoubtedly helps the squeamish passenger keep control of his stomach in bumpy weather better than if they were called "vomit bags." Other forms of self-deception may not be beneficial, but may still be emotionally necessary. A girl may tolerate herself more readily if she thinks of herself as a "swinger" rather than as promiscuous. Voyeurs can salve their guilt feelings when they buy tickets for certain "adult entertainments" on the ground that they are implicitly supporting "freedom of artistic expression."
Lexicographer Bergen Evans of Northwestern University believes that euphemisms persist because "lying is an indispensable part of making life tolerable." It is virtuous, but a bit beside the point, to contend that lies are deplorable. So they are; but they cannot be moralized or legislated away, any more than euphemisms can be. Verbal miasma, when it deliberately obscures truth, is an offense to reason. But the inclination to speak of certain things in uncertain terms is a reminder that there will always be areas of life that humanity considers too private, or too close to feelings of guilt, to speak about directly. Like stammers or tears, euphemisms will be created whenever men doubt, or fear, or do not know. The instinct is not wholly unhealthy; there is a measure of wisdom in the familiar saying that a man who calls a spade a spade is fit only to use one.
