One of the problems in all work is to place things in their right order, in the order of origin and importance. This difficulty is almost insoluble when one studies the character of man. As we see him in operation, the synthesis is so complete that we can hardly discern the component parts. Inheritance, social pressure, excitement, interest, love, hate, self-interest, duty and obligation, --these are not unitary in the least and there is constantly a false dissection to be made, an artefact, in order that clearness in presentation may be obtained. We see men as discharging energy in work and play, in the activities that help or hurt themselves and the race. They obtain that energy from the world without, from the sunshine, the air, the plants and the animals; it is built up in their bodies, it is discharged either because some inner tension builds up a desire or because some outer stimulus, environmental or social, directs it. Though we have no way of measuring one man's energy against another, we say, perhaps erroneously, "He is very energetic," or "He is not"; "He is tireless," or "He breaks down easily." As students of character, we must take this question of the energies of men into account as integral in our study. Granting that the human being takes in energy as food and drink and builds it up into dischargeable tissues, we are not further concerned with the details of its physiology. How does the feeling of energy arise, what increases the energy discharge and what blocks, inhibits or lowers it? For from day to day, from hour to hour, we are conscious either of a desire to be active, a feeling of capacity or the reverse. We depend on that feeling of capacity to guide us, and though it is organic, it has its mysterious disappearances and marvelous reenforcements. It arises, so we assume, from the visceral-neuronic activities, subconsciously, in the sense we have used that word. It therefore fluctuates with health, with fatigue, with the years. We marvel at the energy of childhood and youth, and the deepest sadness we have is the depletion of energy-feeling in old age. We love energy in ourselves and we yield admiration, willing or unwilling, to its display in others. The Hero, the leader, is always energetic. In our times, in America, we demand "pep," action and energy-display as an essential in our play and in our work, and we worship quite too frankly where all men have always worshiped. What besides the organic activity, besides health and well-being, excites the feeling of energy and what depresses it?
