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. First of all, languages are by this simplification rendered more prolix, several words having become necessary to express what could have been expressed by a single word before. Thus the words, _Dei_ and, _Deo_, in the Latin, sufficiently show, without any addition, what relation, the object signified is understood to stand in to the objects expressed by the other words in the sentence. But to express the same relation in English, and in all other modern languages, we must make use of, at least, two words, and say, _of God_, _to God_. So far as the declensions are concerned, therefore, the modern languages are much more prolix than the ancient. The difference is still greater with regard to the conjugations. What a Roman expressed by the single word, _amavissem_, an Englishman is obliged to express by four different words, _I should have loved_. It is unnecessary to take any pains to show how much this prolixness must enervate the eloquence of all modern languages. How much the beauty of any expression depends upon its conciseness, is well known to those who have any experience in composition.
