It is probably in some such manner as this, that almost all verbs have become personal, and that mankind have learned by degrees to split and divide almost every event into a great number of metaphysical parts, expressed by the different parts of speech, variously combined in the different members of every phrase and sentence.[29] The same sort of progress seems to have been made in the art of speaking as in the art of writing. When mankind first began to attempt to express their ideas by writing, every character represented a whole word. But the number of words being almost infinite, the memory found itself quite loaded and oppressed by the multitude of characters which it was obliged to retain. Necessity taught them, therefore, to divide words into their elements, and to invent characters which should represent, not the words themselves, but the elements of which they were composed. In consequence of this invention, every particular word came to be represented, not by one character, but by a multitude of characters; and the expression of it in writing became much more intricate and complex than before. But though particular words were thus represented by a greater number of characters, the whole language was expressed by a much smaller, and about four and twenty letters were found capable of supplying the place of that immense multitude of characters, which were requisite before. In the same manner, in the beginnings of language, men seem to have attempted to express every particular event, which they had occasion to take notice of, by a particular word, which expressed at once the whole of that event. But as the number of words must, in this case, have become really infinite, in consequence of the really infinite variety of events, men found themselves partly compelled by necessity, and partly conducted by nature, to divide every event into what may be called its metaphysical elements, and to institute words, which should denote not so much the events, as the elements of which they were composed. The expression of every particular event, became in this manner more intricate and complex, but the whole system of the language became more coherent, more connected, more easily retained and comprehended.
