But everything we say is metaphorical if we choose to be captious. Scratch the simplest expressions, and you will find the metaphor. Written words are handage, inkage and paperage; it is only by metaphor, or substitution and transposition of ideas, that we can call them language. They are indeed potential language, and the symbols employed presuppose nouns, verbs, and the other parts of speech; but for the most part it is in what we read between the lines that the profounder meaning of any letter is conveyed. There are words unwritten and untranslatable into any nouns that are nevertheless felt as above, about and underneath the gross material symbols that lie scrawled upon the paper; and the deeper the feeling with which anything is written the more pregnant will it be of meaning which can be conveyed securely enough, but which loses rather than gains if it is squeezed into a sentence, and limited by the parts of speech. The language is not in the words but in the heart-to-heartness of the thing, which is helped by words, but is nearer and farther than they. A correspondent wrote to me once, many years ago, "If I could think to you without words you would understand me better." But surely in this he was thinking to me, and without words, and I did understand him better. . . . So it is not by the words that I am too presumptuously venturing to speak to- night that your opinions will be formed or modified. They will be formed or modified, if either, by something that you will feel, but which I have not spoken, to the full as much as by anything that I have actually uttered. You may say that this borders on mysticism. Perhaps it does, but there really is some mysticism in nature. To return, however, to terra firma. I believe I am right in saying that the essence of language lies in the intentional conveyance of ideas from one living being to another through the instrumentality of arbitrary tokens or symbols agreed upon and understood by both as being associated with the particular ideas in question. The nature of the symbol chosen is a matter of indifference; it may be anything that appeals to human senses, and is not too hot or too heavy; the essence of the matter lies in a mutual covenant that whatever it is shall stand invariably for the same thing, or nearly so. We shall see this more easily if we observe the differences between written and spoken language. The written word "stone," and the spoken word, are each of them symbols arrived at in the first instance arbitrarily. They are neither of them more like the other than they are to the idea of a stone which rises before our minds, when we either see or hear the word, or than this idea again is like the actual stone itself, but nevertheless the spoken symbol and the written one each alike convey with certainty the combination of ideas to which we have agreed to attach them.
