None the less, while manners have this intrinsic utility, in the apprehension of the performer and the beholder alike, this sense of the intrinsic rightness of decorum is only the proximate ground of the vogue of manners and breeding. Their ulterior, economic ground is to be sought in the honorific character of that leisure or non-productive employment of time and effort without which good manners are not acquired. The knowledge and habit of good form come only by long-continued use. Refined tastes, manners, habits of life are a useful evidence of gentility, because good breeding requires time, application and expense, and can therefore not be compassed by those whose time and energy are taken up with work. A knowledge of good form is prima facie evidence that that portion of the well-bred person’s life which is not spent under the observation of the spectator has been worthily spent in acquiring accomplishments that are of no lucrative effect. In the last analysis the value of manners lies in the fact that they are the voucher of a life of leisure.
