[173] Of course the matter as well as the manner of converse was restricted; and the nature of the restraints upon free speech can be inferred from the nature of the restraints upon freedom of demeanour. Demeanour was most elaborately and mercilessly regulated, not merely as to obeisances, of which there were countless grades, varying according to sex as well as class,--but even in regard to facial expression, the manner of smiling, the conduct of the breath, the way of sitting, standing, walking, rising. Everybody was trained from infancy in this etiquette of expression and deportment. At what period it first became a mark of disrespect to betray, by look or gesture, any feeling of grief or pain in the presence of a superior, we cannot know; there is reason to believe that the most perfect self-control in this regard was enforced from prehistoric times. But there was gradually developed--partly, perhaps, under Chinese teaching--a most elaborate code of deportment which exacted very much more than impassiveness. It required not only that any sense of anger or pain should be denied all outward expression, but that the sufferer's face and manner should indicate the contrary feeling. Sullen submission was an offence; mere impassive obedience inadequate: the proper degree of submission should manifest itself by a pleasant smile, and by a soft and happy tone of voice. The smile, however, was also regulated. [174] One had to be careful about the quality of the smile: it was a mortal offence, for example, so to smile in addressing a superior, that the back teeth could be seen. In the military class especially this code of demeanour was ruthlessly enforced. Samurai women were required, like the women of Sparta, to show signs of joy on hearing that their husbands or sons had fallen in battle: to betray any natural feeling under the circumstances was a grave breach of decorum. And in all classes demeanour was regulated so severely that even to-day the manners of the people everywhere still reveal the nature of the old discipline. The strangest fact is that the old-fashioned manners appear natural rather than acquired, instinctive rather than made by training. The bow,--the sibilant in drawing of the breath which accompanies the prostration, and is practised also in praying to the gods,--the position of the hands upon the floor in the moment of greeting or of farewell,--the way of sitting or rising or walking in presence of a guest,--the manner of receiving or presenting anything,--all these ordinary actions have a charm of seeming naturalness that mere teaching seems incapable of producing. And this is still more true of the higher etiquette,--the exquisite etiquette of the old-time training in cultivated classes, --particularly as displayed by women. We must suppose that the capacity to acquire such manners depends considerably upon inheritance,--that it could only have [175] been formed by the past experience of the race under discipline.
