because this method is employed is there intellectual discipline and an educative result. The presence of adult activities plays an enormous rôle in the intellectual growth of the child because they add to the natural stimuli of the world new stimuli which are more exactly adapted to the needs of a human being, which are richer, better organized, more complex in range, permitting more flexible adaptations, and calling out novel reactions. But in utilizing these stimuli the child follows the same methods that he uses when he is forced to think in order to master his body.
§ 2. Play, Work, and Allied Forms of Activity
Play indicates the domination of activity by meanings or ideas When things become signs, when they gain a representative capacity as standing for other things, play is transformed from mere physical exuberance into an activity involving a mental factor. A little girl who had broken her doll was seen to perform with the leg of the doll all the operations of washing, putting to bed, and fondling, that she had been accustomed to perform with the entire doll. The part stood for the whole; she reacted not to the stimulus sensibly present, but to the meaning suggested by the sense object. So children use a stone for a table, leaves for plates, acorns for cups. So they use their dolls, their trains, their blocks, their other toys. In manipulating them, they are living not with the physical things, but in the large world of meanings, natural and social, evoked by these things. So when children play horse, play store, play house or making calls, they are subordinating the physically present to the ideally signified. In this way, a world of meanings, a store of concepts (so fundamental to all intellectual achievement), is defined and built up.
