Now, I wish to call attention to the very important fact that the origin and development of speech, and later, of writing, were apparently almost simultaneous, and certainly quite independent of each other, in countries not very distant apart. This is shown by the radical diversity of the different groups of languages in Europe, Eastern Asia and North Africa, and the equal diversity of Egyptian, Assyrian, and Chinese writing. All other written characters are believed to be derived from one or other of these, and it is known that the forms and peculiarities of alphabetic characters have been greatly modified by the various materials employed, such as wood and stone slabs, clay, or wax; papyrus, paper or parchment; and whether engraved, impressed or painted, whether written with a reed or quill pen, or with a small brush. But if intellectual man as a species of mammal had developed by the preservation of variations of survival-value, we should expect to find such an important faculty as speech to have originated in one centre and to have spread rapidly over the world with only slight modifications in isolated communities. The fundamental diversities we find seem to accord better with the conception that when, as a mere animal, his material organism had reached the required degree of perfection, there occurred the spiritual influx which alone enabled him to begin that course of intellectual and moral development, and that marvellous power over the forces of Nature, in which speech and writing, followed by printing, have been such important factors. In order for man to develop speech he must have possessed a brain and an intellect far above that of the brutes. As in the more fundamental problem of the origin of life, it is admitted that organisation is a product of life—not life of organisation—so we must believe that speech was a product of a brain and an intellect sufficient for their development. But such brain and intellect were not necessary for the lower animals, which have reached their highest lines of development in the dog, horse, elephant, and ape without making any definite approach to the acquirement of such higher faculties. CHAPTER VI SAVAGES NOT MORALLY INFERIOR TO CIVILISED RACES If the facts and arguments set forth in the preceding chapters are correct we should not expect to find any living examples of the unspiritualised man, since the assumption is that the whole race received the influx which started them on their course of purely human development within a strictly limited period, perhaps of a very few generations or even one generation. The ancestral form—the supposed missing link—would then have become extinct.
