THE MATERIAL OF DEVELOPMENT
…The objective material of the old schools was an aid to the teacher in making his explanations comprehensible to a collective class listening passively to him. The objects were related solely to the things to be explained, and these were chosen at random, that is to say, without any scientific criterion of their relation to the psychical needs of the child. Here, on the other hand, the means of development are experimentally determined with reference to the psychical evolution of the child; and their aim is not to give mere instruction; they represent the means which induce a spontaneous interpretation of the internal energies.
The external material is then offered, and left freely to the natural individual energies of the children. They choose the objects they prefer; and such preference is dictated by the internal needs of “psychical growth”. Each child occupies himself with each object chosen for as long as he wishes; and this desire corresponds to the needs of the intimate maturation of the spirit, a process which demands persevering and prolonged exercise. No guide, no teacher can divine the intimate need of each pupil and the time of maturation necessary to each; but only leave the child free, and all this will be revealed to us under the guidance of nature.
