Let us watch that infant as it sprawls in its little bed, the darling of a pair of worshiping parents. In that relationship the child is no solitary individual; society is there already, watching him, nourishing and teaching him. Already he is in the, hands of his group who, though seeking his happiness, are nevertheless determined that he shall obtain it their way. And from then to the end of his life that group will in large measure offer him the criteria of values, and his self-esteem will, in the majority of cases, rest upon his idea of their esteem of him. In the brooding mother, in the tender father lie dormant all the judgments of the time on the conduct and guiding motives of the little one. The baby throws his arms about, kicks his legs, rolls his eyes. In these movements arising from internal activities which, we can only state, relate to vascular distribution, neuronic relations, visceral and endocrinic activities, is the germ of the impulse to activity which it is the function of society and the individual himself to shape into organized useful work. Thus is manifested a native, inherent, potentiality, which we may call the energy of the baby, the energy of man, a something which the environment shapes, but which is created in the laboratory of the individual. The father and mother are delighted with the fine vigorous movements of the child, and there is in that delight the approval that society always gives or tends to give to manifestations of power. We tend involuntarily to admire strength, even though misdirected. The strong man always has followers though he be a villain, and in fact the history of man is to a large extent based on the fact that the strong man evokes enthusiasm and obedience. This impulse to activity is an unrest, and its satisfaction lies in movement; in other words there is a pleasure or a relief in mere activity. The need of discharging energy, the desire to do so, the pleasure and satisfaction in so doing constitute a cornerstone of the foundation of life and character. This desire for activity, as we shall call it henceforth, is behind work and play; it fluctuates with health and disease, with youth and old age; it becomes harnessed to purpose, it is called into being by motives or inhibited by conflict and indecision and its organization is the task of society. Men differ in regard to the desire for activity, with a range from the inert whose energy is low to the dynamic types that are ever busy and ever seeking more to do.
