The point of these remarks is that play has an end in the sense of a directing idea which gives point to the successive acts. Persons who play are not just doing something (pure physical movement); they are trying to do or effect something, an attitude that involves anticipatory forecasts which stimulate their present responses. The anticipated result, however, is rather a subsequent action than the production of a specific change in things. Consequently play is free, plastic. Where some definite external outcome is wanted, the end has to be held to with some persistence, which increases as the contemplated result is complex and requires a fairly long series of intermediate adaptations. When the intended act is another activity, it is not necessary to look far ahead and it is possible to alter it easily and frequently. If a child is making a toy boat, he must hold on to a single end and direct a considerable number of acts by that one idea. If he is just "playing boat" he may change the material that serves as a boat almost at will, and introduce new factors as fancy suggests. The imagination makes what it will of chairs, blocks, leaves, chips, if they serve the purpose of carrying activity forward. From a very early age, however, there is no distinction of exclusive periods of play activity and work activity, but only one of emphasis. There are definite results which even young children desire, and try to bring to pass. Their eager interest in sharing the occupations of others, if nothing else, accomplishes this. Children want to "help"; they are anxious to engage in the pursuits of adults which effect external changes: setting the table, washing dishes, helping care for animals, etc. In their plays, they like to construct their own toys and appliances. With increasing maturity, activity which does not give back results of tangible and visible achievement loses its interest. Play then changes to fooling and if habitually indulged in is demoralizing. Observable results are necessary to enable persons to get a sense and a measure of their own powers. When make-believe is recognized to be make-believe, the device of making objects in fancy alone is too easy to stimulate intense action. One has only to observe the countenance of children really playing to note that their attitude is one of serious absorption; this attitude cannot be maintained when things cease to afford adequate stimulation.
