Pedagogues, who make such an imposing display of what they teach, are paid to talk in another strain than mine, but their conduct shows that they think as I do. For after all, what do they teach their pupils? Words, words, words. Among all their boasted subjects, none are selected because they are useful; such would be the sciences of things, in which these professors are unskilful. But they prefer sciences we seem to know when we know their nomenclature, such as heraldry, geography, chronology, languages; studies so far removed from human interests, and particularly from the child, that it would be wonderful if any of them could be of the least use at any time in life.
It may cause surprise that I account the study of languages one of the useless things in education. But remember I am speaking of the studies of earlier years, and whatever may be said, I do not believe that any child except a prodigy, will ever learn two languages by the time he is twelve or fifteen.[11]
I admit that if the study of languages were only that of words, that is, of forms, and of the sounds which express them, it might be suitable for children. But languages, by changing their signs, modify also the ideas they represent. Minds are formed upon languages; thoughts take coloring from idioms. Reason alone is common to all. In each language the mind has its peculiar conformation, and this may be in part the cause or the effect of national character. The fact that every nation's language follows the vicissitudes of that nation's morals, and is preserved or altered with them, seems to confirm this theory.
Of these different forms, custom gives one to the child, and it is the only one he retains until the age of reason. In order to have two, he must be able to compare ideas; and how can he do this when he is scarcely able to grasp them? Each object may for him have a thousand different signs, but each idea can have but one form; he can therefore learn to speak only one language. It is nevertheless maintained that he learns several; this I deny. I have seen little prodigies who thought they could speak six or seven: I have heard them speak German in Latin, French, and Italian idioms successively. They did indeed use five or six vocabularies, but they never spoke anything but German. In short, you may give children as many synonyms as you please, and you will change only their words, and not their language; they will never know more than one.
