Of all the diseases of the mind or the heart, affectation is the fittest subject of ridicule,--since we are ridiculous not for what we are, but for what we pretend to be. One of the arguments of the apologists for this mean and pitiful vice is,--that the ordinary conventional forms of politeness necessarily involve its commission, and that all the tutored and refined graces of polished life, are but its varying forms. Of the former, benevolence should be, if it be not always, the genuine and captivating source; and if we have it not, the assumption of a virtue which inculcates a sacrifice to the feelings of others of our own, may find a sufficient apology, perhaps, for a semblance to which society has learned to affix its value. With regard to the latter, _la belle nature_ is loveliest when embellished, not prostituted, by art, in its most vulgar form, viz: _affectation_. Neither wealth nor fashion can divest it of its character of vulgarity. One should, indeed, be too proud to be _vain_, when vanity leads to affectation,--which in its milder form, is the meanness of asking credit for what we do not possess--and in its deeper die, impels us to obtain it by dissimulation, hypocrisy and fraud. In its approaches, few vices are more insidious. Having its germ in the indiscriminate love of imitation natural to youth, vanity prompts an eager exchange of our native attributes, for what we deem attractive in others--and artifice is speedily resorted to, to give the acquisition the semblance of an original possession. One cherished appropriation is added to another, until the product becomes a complete bundle of fancied charms and perfections, entailing, however, all that anxiety of concealment, whose only tendency is to betray the theft. If the original effects of affectation have been correctly assigned, the mode and importance of prevention will sufficiently suggest themselves. Let parents beware how they suffer their children to be exposed to the contagion of this vile leprosy. Let them carefully remove from them, as from a pestilence, those infected subjects, whose resemblance they would shudder to see them. The garment of affectation once put on, like that of the fated Nessus, grows to the wearer. Should her complacency ever be so far alarmed as to make her attempt to doff it, may vainly fancy she has succeeded, by simply pulling it around, and exhibiting it under a different aspect. Should she be so fortunate as to have the most invaluable, because the rarest of friends,--one who will neither flatter, nor shrink from the task of the faithful anatomy of her heart, and the development of the fatal poison which lurks at its core, and be brought sincerely to desire its removal,--let her, while she earnestly applies to it her own rigid examinations, fervently invoke the aid of a mightier physician, who cleansing her heart, will restore her to a place a little less than the angels, of whom I am an ADORER.
