The Theory of Moral Sentiments - Adam Smith [243]
The English is compounded of the French and the ancient Saxon languages. The French was introduced into Britain by the Norman conquest, and continued, till the time of Edward III, to be the sole language of the law as well as the principal language of the court. The English, which came to be spoken afterwards, and which continues to be spoken now, is a mixture of the ancient Saxon and this Norman French. As the English language, therefore, is more complex in its composition than either the French or the Italian, so is it likewise more simple in its declensions and conjugations. Those two languages retain, at least, a part of the distinction of genders, and their adjectives vary their termination according as they are applied to a masculine or to a feminine substantive. But there is no such distinction in the English language, whose adjectives admit of no variety of termination. The French and Italian languages have, both of them, the remains of a conjugation; and all those tenses of the active voice, which cannot be expressed by the possessive verb joined to the passive participle, as well as many of those which can, are, in those languages, marked by varying the termination of the principal verb. But almost all those other tenses are in the English eked out by other auxiliary verbs, so that there is in this language scarce even the remains of a conjugation. I love, I loved, loving, are all the varieties of termination which the greater part of English verbs admit of. All the different modifications of meaning, which cannot be expressed by any of those three terminations, must be made out by different auxiliary verbs joined to some one or other of them. Two auxiliary verbs supply all the deficiencies of the French and Italian conjugations; it requires more than half a dozen to supply those of the English, which, besides the substantive and possessive verbs, makes use of do, did; will, would; shall, should; can, could; may, might.
It is in this manner that language becomes more simple in its rudiments and principles, just in proportion as it grows more complex in its composition, and the same thing has happened in it, which commonly happens with regard to mechanical engines. All machines are generally, when first invented, extremely complex in their principles, and there is often a particular principle of motion for every particular movement which it is intended they should perform. Succeeding improvers observe, that one principle may be so applied as to produce several of those movements; and thus the machine becomes gradually more and more simple, and produces its effects with fewer wheels, and fewer principles of motion. In language, in the same manner, every case of every noun, and every tense of every verb, was originally expressed by a particular distinct word, which served for this purpose and for no other. But succeeding observation discovered, that one set of words was capable of supplying the place of all that infinite number, and that four or five prepositions, and half a dozen auxiliary verbs, were capable of answering the end of all the declensions, and of all the conjugations in the ancient languages.
But this simplification of languages, though it arises, perhaps, from similar causes, has by no means similar effects with the correspondent simplification of machines. The simplification of machines renders them more and more perfect, but this simplification of the rudiments of languages renders them more and more imperfect, and less proper for many of the purposes of language: and this for the following reasons.9
First of all, languages are by this simplification
