Decorum set out with being symbol and pantomime and with having utility only as an exponent of the facts and qualities symbolised; but it presently suffered the transmutation which commonly passes over symbolical facts in human intercourse. Manners presently came, in popular apprehension, to be possessed of a substantial utility in themselves; they acquired a sacramental character, in great measure independent of the facts which they originally prefigured. Deviations from the code of decorum have become intrinsically odious to all men, and good breeding is, in everyday apprehension, not simply an adventitious mark of human excellence, but an integral feature of the worthy human soul. There are few things which so touch us with instinctive revulsion as a breech of decorum; and so far have we progressed in the direction of imputing intrinsic utility to the ceremonial observances of etiquette that few of us, if any, can dissociate an offence against etiquette from a sense of the substantial unworthiness of the offender. A breach of faith may be condoned, but a breach of decorum cannot. "Manners maketh man."
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.
