The general use of speech, is to transfer our mental discourse, into verbal; or the train of our thoughts, into a train of words; and that for two commodities, whereof one is the registering of the consequences of our thoughts; which being apt to slip out of our memory, and put us to a new labour, may again be recalled, by such words as they were marked by. So that the first use of names is to serve for “marks,” or “notes” of remembrance. Another is, when many use the same words, to signify, by their connection and order, one to another, what they conceive, or think of each matter; and also what they desire, fear, or have any other passion for. And for this use they are called “signs.” Special uses of speech are these; first, to register, what by cogitation, we find to be the cause of anything, present or past; and what we find things present or past may produce, or effect; which in sum, is acquiring of arts. Secondly, to show to others that knowledge which we have attained, which is, to counsel and teach one another. Thirdly, to make known to others our wills and purposes, that we may have the mutual help of one another. Fourthly, to please and delight ourselves and others, by playing with our words, for pleasure or ornament, innocently.
