Of the extensiveness of both these speech-worlds in the waking-consciousness of man we to-day can scarcely form an idea. Expression-speech, which appears in the earliest times with all the religious seriousness of the Taboo, includes not only weighty and strict ornament--which in the beginning coincides completely with the idea of art and makes every stiff, inert thing into a vehicle of the expression--but also the solemn ceremonial--whose web of formulæ spreads over the whole of public life, and even over that of the family[180]--and the language of costume, which is contained in clothing, tattooing, and personal adornment, all of which have a _uniform_ significance. The investigators of the nineteenth century vainly attempted to trace the origin of clothing to the feeling of shame or to utilitarian motives. It is in fact intelligible only as the means of an expression-speech, and as such it is developed to a grandiose level in all the high Civilizations, including our own of to-day. We need only think of the dominant part played by the “mode” in our whole public life and doings, the regulation attire for important occasions, the nuances of wear for this and that social function, the wedding-dress, mourning; of the military uniform, the priest’s robes, orders and decorations, mitre and tonsure, periwig and queue, powder, rings, styles of hairdressing; of all the significant displays and concealments of person, the costume of the mandarin and the senator, the odalisque and the nun; of the court-state of Nero, Saladin and Montezuma--not to mention the details of peasant costumes, the language of flowers, colours, and precious stones. As for the language of religion, it is superfluous to mention it, for all this _is_ religion. The communication-languages, in which every kind of sense-impression that it is possible to conceive more or less participates, have gradually evolved (so far as the peoples of the higher Cultures are concerned) three outstanding signs--picture, sound, and gesture, which in the script-speech of the Western Civilization have crystallized into a unit of letter, word, and punctuation mark.
