The written symbol is formed with the hand, appeals to the eye, leaves a material trace as long as paper and ink last, can travel as far as paper and ink can travel, and can be imprinted on eye after eye practically ad infinitum both as regards time and space. The spoken symbol is formed by means of various organs in or about the mouth, appeals to the ear, not the eye, perishes instantly without material trace, and if it lives at all does so only in the minds of those who heard it. The range of its action is no wider than that within which a voice can be heard; and every time a fresh impression is wanted the type must be set up anew. The written symbol extends infinitely, as regards time and space, the range within which one mind can communicate with another; it gives the writer's mind a life limited by the duration of ink, paper and readers, as against that of his flesh and blood body. On the other hand, it takes longer to learn the rules so as to be able to apply them with ease and security, and even then they cannot be applied so quickly and easily as those attaching to spoken symbols. Moreover, the spoken symbols admit of a hundred quick and subtle adjuncts by way of action, tone and expression, so that no one will use written symbols unless either for the special advantages of permanence and travelling power, or because he is incapacitated from using spoken ones. This, however, is hardly to the point; the point is that these two conventional combinations of symbols, that are as unlike one another as the Hallelujah Chorus is to St. Paul's Cathedral, are the one as much language as the other; and we therefore inquire what this very patent fact reveals to us about the more essential characteristics of language itself. What is the common bond that unites these two classes of symbols that seem at first sight to have nothing in common, and makes the one raise the idea of language in our minds as readily as the other? The bond lies in the fact that both are a set of conventional tokens or symbols, agreed upon between the parties to whom they appeal as being attached invariably to the same ideas, and because they are being made as a means of communion between one mind and another--for a memorandum made for a person's own later use is nothing but a communication from an earlier mind to a later and modified one; it is therefore in reality a communication from one mind to another as much as though it had been addressed to another person.
