Even a distant acquaintance with the first years of human life tells us that young children have much in common with the lower animals. The characteristic feelings and impulses are centred in self and the satisfaction of its wants. What is better marked, for example, than the boundless greed of the child, his keen desire to appropriate and enjoy whatever presents itself, and to resent others' participation in such enjoyment? We note, further, that when later on he makes fuller acquaintance with his social surroundings, his first attitude has in it much of the hostility of the Ishmaelite. The removal of the feeding bottle before full satisfaction has been attained is, as we know, the occasion for one of the most impressive utterances of the baby's "will to live," and of its resentment of all human checks to its native impulses. Here we have the first rude germ of that opposition of will which makes the Ishmaelite look on others as his foes. The same attitude of isolating hostility is apt to show itself towards other children. In the matter of toys, for example, the natural way of a child is very frequently not only to make free with other children's property when he has the chance, but to show the strongest objection to any imitation of this freedom by others, sometimes indeed to display a dog-in-the-manger spirit by refusing to lend what he himself does not want. The same vigorous egoism inspires the whole scale of childish envies and jealousies, from those having to do with things of the appetite to those which trouble themselves about the marks of others' good-will, such as caresses and praises. In this wide category of childish egoisms we seem to be near the level of animal ways. Out of all this fierce pushing of desire whereby the child comes into rude collision with others' wishes, there issue the storms of young passion. The energy of these displays of wrath as the imperious little will feels itself suddenly pulled up has in spite of its comicality something impressive. We all know the shocking scene as the boy Ishmaelite gives clearest and most emphatic utterance to his will by hitting out with his arms, stamping and kicking, throwing things down on the floor and breaking them, and accompanying this war-dance with savage howlings and yellings. The outburst tends to concentrate itself in a real attack on somebody. Sometimes this is the offender, as when Darwin's boy at the age of two years and three months would throw books, sticks, etc., at any one who offended him. But almost anybody or anything will do as an object of attack. A child of four on having his lordly purpose crossed would bang his chair, and then proceed to vent his displeasure on his unoffending toy lion, banging him, jumping on him, and, as anti-climax, threatening him with the loss of his dinner. Hitting is in many cases improved upon by biting.
