We want American customs, habits, manners, dress, manufactures, modes of thought, modes of expression, and language. We should encourage national and even State peculiarities; for there are peculiarities and differences in the wants and situations of all people, that require provincial and national, not cosmopolitan, institutions and productions. Take language, for instance. It is a thing of natural growth and development, and adapts itself naturally to the changes of time and circumstance. It is never ungrammatical as spoken by children, but always expressive, practical and natural. Nature is always grammatical, and language, the child of nature, would continue so, but for the grammarians, who, with their Procrustean rules, disturb its proportions, destroy its variety and adaptation, and retard its growth. They are to language what dentists are to teeth: they more often injure it than improve it. Grammar, lexicography, and rhetoric, applied to language, destroy its growth, variety and adaptability--stereotype it, make it at once essentially a dead language, and unfit for future use; for new localities, and changes of time and circumstances, beget new ideas, and require new words and new combinations of words. Centralization and cosmopolitanism have precisely the same effect. They would furnish a common language from the centre, which is only fully expressive and comprehensive at that centre. Walking and talking are equally natural, and talking masters and walking masters equally useless. Neither can foresee and provide for the thousands of new circumstances which make change of language, or varieties of movement necessary. Nature is never at a loss, and is the only reliable dancing master and grammar teacher. She is always graceful and appropriate, and always ready to adapt herself to changes of time, situation and circumstances. Paris is becoming the universal model and grammar of Christendom; nothing is right unless it be a la Parisienne. Now, in truth, nothing can be right, natural, appropriate, or in good taste, outside of Paris, that is Parisienne. When will our monkey imitative world cease to sacrifice millions of money, cease to show its want of good sense and propriety, and cease to render itself ridiculous by aping, what, in the nature of things, is unsuitable, inappropriate, and unnatural? Fashion, aided by free trade and centralization, is subjecting us to the dominion of Parisian thought; and commerce, by means of the same agencies, makes us tributaries to London. Trade and fashion conquer faster than arms.
