As words, under the analyses now indicated, yield the history of their origin and of the changes both in spelling and meaning which follow their passage from older forms, and likewise reveal the reasons which governed the choice of them, so the letters of which they are made up bear witness to similar laws of development. The story which it is the purpose of this little book to endeavour to extract from them has mutilated and imperfect chapters, and, moreover, missing chapters which may never be recovered. But sufficing material survives for piecing together a narrative of the triumph of the human mind over one of the most difficult tasks to which it could apply itself; a task which, unwrought, would have made advance in the highest sense impossible beyond a certain point. In the highest sense, because man has gone a long way without knowledge either of reading or writing. These "two R's" are not necessary in matters of personal contact with his fellows, while in other ways progress is independent of them. An illiterate man may be an accomplished landscape artist, a skilful engineer, a successful farmer or trader, and prosperous in many ways where the aim of life is to "live by bread alone." It is true that much of the intellectual and spiritual record of man's past was long preserved in the form of oral tradition. But to the volume of such record there is a limit, while time and caprice alike work havoc in it. Memory, great as was its capacity of old, before dependence on books impaired it, was not infallible, nor, as the world's stock of knowledge increased, could it "pull down its barns and build greater wherein to bestow its goods." We have, by an effort of the imagination well-nigh impossible to make, only to assume the absence of any means of material record of the involved and myriad events which fill the world's past, to conceive the intellectual poverty of the present. We have only to assume the absence of any medium whereby we could communicate with friends at a distance, or whereby the now complex and countless dealings between man and man could be set down and every transaction thus "brought to book," to realise the hopeless tangle of our social life. All that memory failed to overlap would be an absolute blank; the dateless and otherwise uninscribed monuments which the past had left behind would but deepen the darkness; all knowledge of the strivings and speculations of men of old would have been unattainable; all observation and experience through which science has advanced from guesses to certainties irretrievably lost; life could have been lived only from "hand to mouth," and the spectacle presented of an arrested world of sentient beings. Save in fragmentary echoes repeated by fugitive bards, the great epics of East and West would have perished, and the immortal literatures of successive ages never have existed. The invention of writing alone made possible the passage from barbarism to
