There is considerable agreement among students of the subject that the emotional energies aroused in connection with the sex instinct may be drained off into other channels, and serve to quicken and sustain both artistic creation and appreciation and social and religious enthusiasms of various kinds. And the sex instinct, as we shall find in our discussion of Racial Continuity (see p. 243) is the basis of the family.
Physical activity. The difference between sticks and stones and living beings consists primarily in the fact that the latter are positively active; the former are passively acted upon. The stone will stay put, unless moved by some external agent, but even the amœba will do something to its environment. It will stretch out pseudopodia to reach solid objects to which to cling; it will attempt to return to these objects when dislodged; it will actively absorb food. Higher up in the animal scale, "Rats run about, smell, dig, or gnaw, without real reference to the business in hand. In the same way Jack (a dog) scrabbles and jumps, the kitten wanders and picks, the otter slips about everywhere like ground lightning, the elephant fumbles ceaselessly, the monkey pulls things about."[2] "The most casual notice of the activities of a young child reveals a ceaseless display of exploring and testing activity. Objects are sucked, fingered and thumped; drawn and pushed, handled and thrown."[3]

When vitality is at its height in the waking period of a young child, its environment is a succession of stimulations to activity. Man's "innate tendency to fool" is notorious, a tendency particularly noticeable in children. Objects are responded to, not as means to ends, not with reference to their use, but simply for the sheer satisfaction of manipulation. Facial expressions, sounds, gestures, are made almost on any provocation; they are the expressions of an abundant "physiological uneasiness." The two-year-old is a mechanism that simply must and will move about, make all kinds of superfluous gestures and facial expressions, and random sounds, as it were, just to get rid of its stored-up energy. Man's laziness and inertia are not infrequently commented on by moralists, but it is not laziness and inertia per se; certainly in normal individuals in the temperate zone, to do something most of their waking time is a natural tendency and one intrinsically pleasant to practice. That the tendency to be active should vary in different individuals and at different times is, of course, as important a fact as it is a familiar one. Some of the causes of this variation will be noted in the succeeding.
In adult life for casual and random activity is substituted activity directed by some end or purpose which determines the responses called into play. Professional and business, domestic and social enterprises and obligations take up most of the adult's energy. The contrast between the play of the child and the work of the adult is that in the case of the former actions are done for their own sake; and in the latter for some end. The child, we say, plays "for the fun of the thing," the adult works for pay, for professional success, for power, reputation, etc.
But even in the adult the desire for play powerfully persists. Not all the grown-up's energy is absorbed in his work, and even some types of work, like that of the poet or painter, or the building-up of a great business organization, may be intrinsically delightful and self-sufficient activity. Under the conditions of modern industry, however, especially of machine production, much—in many cases, most—of the activity by which an individual earns his living, utilizes only some of his native tendencies to act, while the working day does not, under normal conditions, absorb all his energy. Whatever vitality is not, therefore, absorbed in necessary work goes into forms of purely gratuitous activity. Which form "play" shall take in the adult depends on the degree to which certain impulses are in him stronger than others, either by native endowment or cultivation, and which impulses have not been sufficiently utilized in him during the day's work. A man musically gifted will find his recreation in some performance on a musical instrument, let us say; on the other hand, if his work is music, those impulses, strong though they be, that make him a musician, will have been sufficiently exhausted in the day's work to make some other activity a more satisfactory recreation.
The relations between play and work can be better understood by a consideration of the physiological importance of variety in activity. A certain regular recurrence of response may be pleasant, as in rowing or canoeing, or in listening to the rhythms of poetry or music, but a prolonged repetition of precisely the same stimulus or the same set of stimuli may make responses dissatisfying to the degree of pain. Ideal activity, biologically, would be one where every impulse was just sufficiently frequently called upon to make response easy, fluent, and satisfactory.
The reason "work" has traditionally come to be regarded as unpleasant and "play" as pleasant is not because the former is activity and the second is torpor. Leisure does not necessarily mean laziness. Many a vacation, a camping party, a walking expedition, is literally more strenuous than the work an individual normally does. But work means human energy expended for the sole purpose of accomplishing some end. And an end involves the deliberate shutting-out of every impulse which does not contribute to its fulfillment. A man weeding a garden may tire of the weeding long before he is really physically exhausted. One response is being repeatedly made, while at the same time a dozen other impulses are being stimulated. When Tom Sawyer, under the compulsion of his aunt, is whitewashing a fence, it is shortly no fun for him. But he can make other boys pay him apple-cores and jackknives for the fun of wielding the brush.
