We should further note the display of physical charms so far as it can be separated from art, which, indeed, is no easy task, as the boundary line is sometimes almost indistinguishable. Yet it does exist, and we may be able to detect it most readily in the conduct of our budding youths. As a rule, when the other sex begins to interest them they are impelled to make the most of every outward advantage. The boy begins to be neat, to care for his teeth and nails, arrange his hair more carefully, to consider the fit of his clothes, and to indulge in boots and gloves which are too small for him; he puts on high collars and makes a great display of his cuffs, and impatiently awaits the premonitions of a mustache. It is altogether unlikely that he is clear as to the meaning of all this, and in that case he is playing with his personal charms. Such special attention is given to the hair by youths of all classes as to suggest a particular significance for that form of adornment, and the care of the beard naturally goes with it. There are, however, less innocent modes of self-exhibition and some which more unmistakably point to the end which they are intended to serve. The girdle decorations of savages, for instance, are now considered to have a significance quite different from that formerly attributed to them. Their original intention was in all probability to attract attention, not to conceal. Of their ornamental use we are not now speaking, but I confess that I have my doubts of the universal applicability of the explanation just indicated, in spite of the opinion of many competent investigators. Forster speaks of the leaves of a certain species of ginger plant which the male inhabitants of some of the New Hebrides bind to their breech cloths, as outraging in their appearance every law of decency, and Barrow makes the same remark about the Hottentots.[509] Many scholars, too, are disposed to attribute the origin of circumcision to some such beginnings, as there is much against its explanation on religious or sanitary grounds. It is rather surprising that no one has adduced, in support of the modern view of the purposes of courtship served by the articles suspended from the girdle, the strange fashion of projecting front flaps introduced in the fifteenth century. Rabelais’s famous chapter on this subject is merely an exaggeration, not an invention. The reality was certainly bad enough,[510] and as little calculated as are the savage decorations to serve the purposes of modesty. Yet in neither case am I prepared to assert that they belong exclusively to the category of sexual stimuli.
