My purpose requires me to advert in these alleged secondary uses of language, not, however, for the view of counter-arguing them, but rather in order to indicate what seems to me the true mode of bringing them to the proof. The most usual phraseology for describing the indirect benefit of languages is, that they supply a _training_ to the powers of the mind; that, if not information, they are _culture_; that they re-act upon our mastery of our own language, and so on. It is quite necessary, however, to find phrases more definite and tangible than the slippery words "culture" and "training": we must know precisely what particular powers or aptitudes are increased by the study of a foreign language. Nevertheless, the conclusions set forth in this paper do not require me to work out an exhaustive review of these advantages. It is enough to give as many as will serve for examples. Now, it must be freely admitted as a possible case, that a practice introduced in the first instance for a particular purpose, may be found applicable to many other purposes; so much so, that, ceasing to be employed for the original use, the practice may be kept up for the sake of the after uses. For example, clothing was no doubt primarily contrived for warmth; but it is not now confined to that: decoration or ornament, distinction of sexes, ranks and offices, modesty--are also attained by means of clothes. This example is a suggestive one. We have only to suppose ourselves migrating to some African climate, where clothing for warmth is absolutely dispensed with. We should not on that account adopt literal nudity--we should still desire to maintain those other advantages. The artistic decoration of the person would continue to be thought of; and, as no amount of painting and tattooing, with strings of beads superadded, would answer to our ideal of personal elegance, we should have recourse to some light filmy textures, such as would allow the varieties of drapery, colours, and design, and show off the poetry of motion; we should also indicate the personal differences that we were accustomed to show by vesture. But now comes the point of the moral; we should not maintain our close heavy fabrics, our great-coats, shawls and cloaks. These would cease with the need for them. Perhaps the first emigrants would keep up the prejudice for their warm things, but not so their successors.
