The energy of the individual. Some are so constituted that they can constantly discharge their energy at a high rate. These are the dynamics, the hyperkinetic, the Rooseveltian--strenuous--the busy people, always able to do more. The modern American life holds this type as an ideal, though it is quite questionable whether these rather over-busy people do not lose in reflective and creative ability. The rushing stream turns the wheels of the mills, but it is too strenuous for stately ships. This type however achieves things, is seen often in the fine executive and usually needs no urging. There is another fine type not so well adapted to our civilization, which is easily exhausted, but can accomplish very much in a short time; in other words discharges energy intermittently at a high rate. Charles Darwin was of this kind--intermittently hyperkinetic --obliged to rest after an hour's labor, but by understanding this, WILLING to rest. Unfortunately, unless one is a genius or rich, industry does not make allowances for this type. Industry is organized on steadiness of energy discharge,--eight hours every day, six days a week. The commonest type is the "average" person who is capable of moderately intense but constant activity. This is the steady man and woman; it is upon this steadiness that the whole factory--shop system--is based. That this steadiness deadens, injures vivacity and makes for restlessness, is another matter. A distinctly pathological type is found in some feebleminded and some high mentalities. This unfortunate discharges energy at a low rate is slow in action and often intermittent as well as hypokinetic. The loafer and the tramp are of this type. Around the water front of the seaports one can find the finest specimens who do odd jobs for as much as will pay for lodging and food and drink. Perhaps the order of the desired rewards should be reversed. Every village furnishes individuals of this group, either unable or unwilling to work consecutively or with energy. Often purposeless day-dreamers or else bereft of normal human mentality, these are the chronically unemployed of our social- industrial system.
