Perhaps next to dancing in phyletic motivation come personal conflicts, such as wrestling, fighting, boxing, dueling, and in some sense, hunting. The animal world is full of struggle for survival, and primitive warfare is a wager of battle, of personal combat of foes contesting eye to eye and hand to hand, where victory of one is the defeat and perhaps death of the other, and where life is often staked against life. In its more brutal forms we see one of the most degrading of all the aspects of human nature. Burk[10] has shown how the most bestial of these instincts survive and crop out irresistibly in boyhood, where fights are often engaged in with desperate abandon. Noses are bitten, ears torn, sensitive places kicked, hair pulled, arms twisted, the head stamped on and pounded on stones, fingers twisted, and hoodlums sometimes deliberately try to strangle, gouge out an eye, pull off an ear, pull out the tongue, break teeth, nose, or bones, or dislocate jaws or other joints, wring the neck, bite off a lip, and torture in utterly nameless ways. In unrestrained anger, man becomes a demon in love with the blood of his victim. The face is distorted, and there are yells, oaths, animal snorts and grunts, cries, and then exultant laughter at pain, and each is bruised, dirty, disheveled and panting with exhaustion. For coarser natures, the spectacle of such conflicts has an intense attraction, while some morbid souls are scarred by a distinct phobia for everything suggestive of even lower degrees of opposition. These instincts, more or less developed in boyhood, are repressed in normal cases before strength and skill are sufficiently developed to inflict serious bodily injury, while without the reductives that orthogenetic growth brings they become criminal. Repulsive as are these grosser and animal manifestations of anger, its impulsion can not and should not be eliminated, but its expression transformed and directed toward evils that need all its antagonism. To be angry aright is a good part of moral education, and non-resistance under all provocations is unmanly, craven, and cowardly.[11] An able-bodied young man, who can not fight physically, can hardly have a high and true sense of honor, and is generally a milksop, a lady-boy, or sneak. He lacks virility, his masculinity does not ring true, his honesty can not be sound to the core. Hence, instead of eradicating this instinct, one of the great problems of physical and moral pedagogy is rightly to temper and direct it.
