When one realizes the great variety or differences in ability or capacity, as determined by heredity, and when there is added to this difference in original nature the fact of variety in training which children have experienced prior to their school life, he cannot fail to emphasize the necessity for individualizing children. While it is true that we may assume that all children will take delight in achievement, it may be necessary with one child to stir as much as possible the spirit of rivalry, to give as far as one can the delight which comes from success, while for another child in the same class one may need to minimize success on account of a spirit of arrogance which has been developed before school life began. It is possible to conceive of a situation in which some children need to be encouraged to fight, even to the extent of engaging in physical combat, in order to develop a kind of courage which will accept physical discomfort rather than give up a principle or ideal. In the same group there may be children for whom the teacher must work primarily in terms of developing, in so far as he can, the willingness to reason or discuss the issue which may have aroused the fighting instinct.
For all children in elementary and in high schools the possibility of utilizing their original nature for the sake of that development which will result in action which is socially desirable is still present. The problem which the teacher faces will be more or less difficult in proportion as the child's endowment by original nature is large or small, and as previous education has been successful or unsuccessful. The skillful teacher is the one who will constantly seek to utilize to the full those instincts or capacities which seem most potent. This utilization, as has already been pointed out, does not mean a blind following of the instinctive tendencies, but often the substitution of a higher form of action for a lower, which may seem to be related to the instinct in question. It is probably wise to encourage collections of stamps, of pictures, of different kinds of wood, and the like, upon the part of children in the elementary school, provided always that the teacher has in mind the possibility of leading these children, through their interest in objects, to desire to collect ideas. Indeed, a teacher might measure her success in utilizing the collecting instinct in proportion as children become relatively less interested in things collected, and more interested in the ideas suggested by them, or in the mastery of fields of knowledge or investigation in which objects have very little significance. The desire for physical activity upon the part of children is originally satisfied by very crude performances. Development is measured not simply in an increase in manual dexterity, but also in terms of the higher satisfaction which may come from producing articles which have artistic merit, or engaging in games of skill which make for the highest physical efficiency.
During the whole period of childhood and adolescence we may never assume that the results of previous education, whether they be favorable or unsatisfactory, are permanent. Whether we succeed or not in achieving the ends which we desire, the fact of modifiability, of docility, and of plasticity remains. The teacher who seeks to understand the individuals with whom he works, both in terms of their original nature and in terms of their previous education, and who at the same time seeks to substitute for a lower phase of an instinctive tendency a higher one, or who tries to have his pupils respond to a situation by inhibiting a particular tendency by forming the habit of meeting the situation in another way, need not despair of results which are socially desirable.
