But as the event, or matter of fact, which is expressed by a verb, may be affirmed either of the person who speaks, or of the person who is spoken to, as well as of some third person or object, it became necessary to fall upon some method of expressing these two peculiar relations of the event. In the English language this is commonly done, by prefixing, what are called the personal pronouns, to the general word which expresses the event affirmed. _I came_, _you came_, _he_ or _it came_; in these phrases the event of having come is, in the first, affirmed of the speaker; in the second, of the person spoken to; in the third, of some other person, or object. The first formers of language, it may be imagined, might have done the same thing, and prefixing in the same manner the two first personal pronouns, to the same termination of the verb, which expressed the third person singular, might have said, _ego venit_, _tu venit_, as well as _ille_ or _illud venit_. And I make no doubt but they would have done so, if at the time when they had first occasion to express these relations of the verb, there had been any such words as either _ego_ or _tu_ in their language. But in this early period of the language, which we are now endeavouring to describe, it is extremely improbable that any such words would be known. Though custom has now rendered them familiar to us, they, both of them, express ideas extremely metaphysical and abstract. The word _I_, for example, is a word of a very particular species. Whatever speaks may denote itself by this personal pronoun. The word _I_, therefore, is a general word, capable of being predicated, as the logicians say, of an infinite variety of objects. It differs, however, from all other general words in this respect; that the objects of which it may be predicated, do not form any particular species of objects distinguished from all others. The word _I_, does not, like the word _man_, denote a particular class of objects, separated from all others by peculiar qualities of their own. It is far from being the name of a species, but, on the contrary, whenever it is made use of, it always denotes a precise individual, the particular person who then speaks. It may be said to be, at once, both what the logicians call, a singular, and what they call, a common term; and to join in its signification the seemingly opposite qualities of the most precise individuality, and the most extensive generalization. This word, therefore, expressing so very abstract and metaphysical an idea, would not easily or readily occur to the first formers of language. What are called the personal pronouns, it may be observed, are among the last words of which children learn to make use. A child, speaking of itself, says, _Billy walks_, _Billy sits_, instead of _I walk_, _I sit_. As in the beginnings of language, therefore, mankind seem to have evaded the invention of at least the more abstract proportions, and to have
