of development every variational tendency in mothers to dote on their children was rewarded by the survival of these children, and the consequent survival of the stock, owing to better nutrition, protection, and training. Of course, this inherited interest in children is shared by the males of the group also, though not in the same degree, and there is reason to believe also that the interest of the male parent in children is acquired in a great degree indirectly and socially through his more potent desire to associate with the mother. This interest and providence on the score of offspring has also a characteristic expression on the mental side. All sense-perceptions are colored and all judgments biased where the child is in question, and affection for it extends to the particular marks which distinguish it. Not only its physical features, but its dress and little shoes, its toys and everything it has touched take on a peculiar aspect. On the organic side, therefore, there is developed a tendency, both in connection with reactions to stimulations in general and in connection with reproductive life in particular, to seize on particular aspects and to be obsessed by them to the exclusion or disparagement of other aspects. The feelings of love and hate, and the broader feelings of race-prejudice and patriotism are consequently based first of all in the instincts. Perhaps the most particular and interesting expression of the general fact of susceptibility is seen in the sensitiveness of man to the opinion in which he is held by others. Social life in every stage of society is characterized by an eagerness to make a striking effect. A bare reference to the ethnological facts in this connection will suffice: The Kite Indians have a society of young men so brave and so ostentatious of their bravery that they will not fight from cover nor turn aside to avoid running into an ambuscade or a hole in the ice. The African has the privilege of cutting a gash six inches long in his thigh for every man he has killed. The Melanesian who is planning revenge sets up a stick or stone where it can be seen; he refuses to eat, and stays away from the dance; he sits silent in the council and answers questions by whistling and by other signs draws attention to himself and has it understood that he is a brave and dangerous man, and that he is biding his time.[162] This bidding for the good opinion of others has plainly a connection with food-getting, and with the conflict side of life. High courage is praised and valued by society, and a man of courage is less imposed on by others, and comes in for substantial recognition and the favor of women. It is thus of advantage to act in such a way as to get public approval and some degree of appreciation; and a degree of sensibility on the score of the opinion of others, or at least a reckoning upon this, is involved in the process of personal adjustment.
