CONDITIONS OF GROWTH AND DEVELOPMENT
A. Physical Growth.—Although differing in their particular conception of the nature of education, all educators agree in setting the child as the central figure in the educative process. As an individual, the child, like other living organisms, develops through a process of inner changes which are largely conditioned by outside influences. In the case of animals and plants, physical growth, or development, is found to consist of changes caused in the main through the individual responding to external stimulation. Taking one of the simplest forms of animal life, for example, the amoeba, we find that when stimulated by any foreign matter not constituting its food, say a particle of sand, such an organism at once withdraws itself from the stimulating elements. On the other hand, if it comes in contact with suitable food, the amoeba not only flows toward it, but by assimilating it, at once begins to increase in size, or grow, until it finally divides, or reproduces, itself as shown in the following figures. Hence the amoeba as an organism is not only able to react appropriately toward different stimuli, but is also able to change itself, or develop, by its appropriate reactions upon such stimulations.
In plant life, also, the same principle holds. As long as a grain of corn, wheat, etc., is kept in a dry place, the life principle stored up within the seed is unable to manifest itself in growth. When, on the other hand, it is appropriately stimulated by water, heat, and light, the seed awakens to life, or germinates. In other words, the seed reacts upon the external stimulations of water, heat, and light, and manifests the activity known as growth, or development. Thus all physical growth, whether of the plant or the animal, is conditioned on the energizing of the inherent life principle, in response to appropriate stimulation of the environment.
A. Simple amoeba.
B. An amoeba developing as a result of assimilating food.
C. An amoeba about to divide, or propagate.
B. Development in Human Life.—In addition to its physical nature, human life has within it a spiritual law, or principle, which enables the individual to respond to suitable stimulations and by that means develop into an intelligent and moral being. When, for instance, waves of light from an external object stimulate the nervous system through the eye, man is able, through his intelligent nature, to react mentally upon these stimulations and, by interpreting them, build up within his experience conscious images of light, colour, and form. In like manner, when the nerves in the hand are stimulated by an external object, the mind is able to react upon the impressions and, by interpreting them, obtain images of touch, temperature, and weight. In the sphere of action, also, the child who is stimulated by the sight of his elder pounding with a hammer, sweeping with a broom, etc., reacts imitatively upon such stimulations, and thus acquires skill in action. So also when stimulated by means of his human surroundings, as, for example, through the kindly acts of his mother, father, etc., he reacts morally toward these stimulations and thus develops such social qualities as sympathy, love, and kindness. Nor are the conditions of development different in more complex intellectual problems. If a child is given nine blocks on which are printed the nine digits, and is asked to arrange them in the form of a square so that each of the horizontal and the vertical columns will add up to fifteen, there is equally an inner growth through stimulation and response. In such a case, since the answer is unknown to the child, the problem serves as a stimulation to his mind. Furthermore, it is only by reacting upon this problem with his present knowledge of the value of the various digits when combined in threes, as 1, 6, 8; 5, 7, 3; 9, 2, 4; 1, 5, 9; etc., that the necessary growth of knowledge relative to the solution of the problem will take place within the mind.
WORTH IN HUMAN LIFE
But the possession of an intellectual and moral nature which responds to appropriate stimulations implies, also, that as man develops intellectually, he will find meaning in human life as realized in himself and others. Thus he becomes able to recognize worth in human life and to determine the conditions which favour its highest growth, or development.
The Worthy Life not a Natural Growth.—Granting that it is thus possible to recognize that "life is not a blank," but that it should develop into something of worth, it by no means follows that the young child will adequately recognize and desire a worthy life, or be able to understand and control the conditions which make for its development. Although, indeed, there is implanted in his nature a spiritual tendency, yet his early interests are almost wholly physical and his attitude impulsive and selfish. Left to himself, therefore, he is likely to develop largely as a creature of appetite, controlled by blind passions and the chance impressions of the moment. Until such time, therefore, as he obtains an adequate development of his intellectual and moral life, his behaviour conforms largely to the wants of his physical nature, and his actions are irrational and wasteful. Under such conditions the young child, if left to himself to develop in accordance with his native tendencies through the chance impressions which may stimulate him from without, must fall short of attaining to a life of worth. For this reason education is designed to control the growth, or development, of the child, by directing his stimulations and responses in such a way that his life may develop into one of worth.
Character of the Worthy Life.—If, however, it is possible to add to the worth of the life of the child by controlling and modifying his natural reactions, the first problem confronting the scientific educator is to decide what constitutes a life of worth. This question belongs primarily to ethics, or the science of right living, to which the educator must turn for his solution. Here it will be learned that the higher life is one made up of moral relations. In other words, the perfect man is a social man and the perfect life is a life made up of social rights and duties, wherein one is able to realize his own good in conformity with the good of others, and seek his own happiness by including within it the happiness of others. But to live a life of social worth, man must gain such control over his lower physical wants and desires that he can conform them to the needs and rights of others. He must, in other words, in adapting himself to his social environment, develop a sense of duty toward his fellows which will cause him to act in co-operation with others. He must refuse, for instance, to satisfy his own want by causing want to others, or to promote his own desires by giving pain to others. Secondly, he must obtain such control over his physical surroundings, including his own body, that he is able to make these serve in promoting the common good. In the worthy life, therefore, man has so adjusted himself to his fellow men that he is able to co-operate with them, and has so adjusted himself to his physical surroundings that he is able to make this co-operation effective, and thus live a socially efficient life.
FACTORS IN SOCIAL EFFICIENCY
A. Knowledge, a Factor in Social Efficiency.—The following simple examples will more fully demonstrate the factors which enter into the socially efficient life. The young child, for instance, who lives on the shore of one of our great lakes, may learn through his knowledge of colour to distinguish between the water and the sky on the horizon line. This knowledge, he finds, however, does not enter in any degree into his social life within the home. When on the same basis, however, he learns to distinguish between the ripe and the unripe berries in the garden, he finds this knowledge of service in the community, or home, life, since it enables him to distinguish the fruit his mother may desire for use in the home. One mark of social efficiency, therefore, is to possess knowledge that will enable us to serve effectively in society.
B. Skill, a Factor in Social Efficiency.—In the sphere of action, also, the child might acquire skill in making stones skip over the surface of the lake. Here,
