_The Use of Manuscripts and Books Made Permanent Records_.--At first all records were made by pen, pencil, or stylus, and manuscripts were represented on papyrus paper or parchment, and could only be duplicated by copying. In Alexandria before the Christian era one could buy a copy of the manuscript of a great author, but it was at a high price. It finally became customary for monks, in their secluded retreats, to spend a good part of their lives in copying and preserving { 129} the manuscript writings of great authors. But it was not until printing was invented that the world of letters rapidly moved forward. Probably about the sixth century A.D. the Chinese began to print a group of characters from blocks, and by the tenth century they were engaged in keeping their records in this way. Gutenberg, Faust, and others improved upon the Chinese method by a system of movable type. But what a wonderful change since the fourteenth century printing! Now, with modern type-machines, fine grades of paper made by improved machinery, and the use of immense steam presses, the making of an ordinary book is very little trouble. Looking back over the course of events incident to the development of the modern complex and flexible language we observe, first, the rude picture scrawled on horn or rock. This was followed by the representation of the sound of the name of the picture, which passed into the mere sound sign. Finally, the relation between the figure and the sound becomes so arbitrary that the child learns the a, b, c as pure signs representing sounds which, in combination, make words which stand for ideas.
_Language Is an Instrument of Culture_.--Culture areas always spread beyond the territory of language groups. Culture depends upon the discovery and utilization of the forces of nature through invention and adaptation. It may spread through imitation over very large human territory. Man has universal mental traits, with certain powers and capacities that are developed in a relative order and in a degree of efficiency; but there are many languages and many civilizations of high and low degree. Through human speech the life of the past may be handed on to others and the life of the present communicated to one another. The physiological power of speech which exists in all permits every human group to develop a language in accordance with its needs and as influenced by its environment. Thus language advanced very rapidly as an instrument of communication even at a very early period of cultural development. A recent study of the { 130} languages of the American Indians has shown the high degree of the art of expression among people of the Neolithic culture. This would seem to indicate that primitive peoples are more definite in thought and more observant in the relation of cause and effect than is usually supposed. Thus, definite language permits more precise thought, and definite thought, in turn, insists on more exact expression in language. The two aid each other in development of cultural ideas, and invention and language move along together in the development of the human race. It becomes a great human invention, and as such it not only preserves the thoughts of the past but unlocks the knowledge of the present.
