By the study of realities wisdom is built up. In the relations of objects he can touch and move, the child comes to find the limitations of his powers, the laws that govern phenomena, and to which his actions must be in obedience. So long as he deals with realities, these laws stand in their proper relation. "So simple, so natural, so true," says Agassiz. "This is the charm of dealing with Nature herself. She brings us back to absolute truth so often as we wander."
So long as a child is lead from one reality to another, never lost in words or in abstractions, so long this natural relation remains. What can I do with it? is the beginning of wisdom. What is it to me? is the basis of personal virtue.
While a child remains about the home of his boyhood, he knows which way is north and which is east. He does not need to orientate himself, because in his short trips he never loses his sense of space direction. But let him take a rapid journey in the cars or in the night, and he may find himself in strange relations. The sun no longer rises in the east, the sense of reality in directions is gone, and it is a painful effort for him to join the new impressions to the old. The process of orientation is a difficult one, and if facing the sunrise in the morning were a deed of necessity in his religion, this deed would not be accurately performed.
This homely illustration applies to the child. He is taken from his little world of realities, a world in which the sun rises in the east, the dogs bark, the grasshopper leaps, the water falls, and the relation of cause and effect appear plain and natural. In these simple relations moral laws become evident. "The burnt child dreads the fire," and this dread shows itself in action. The child learns what to do next, and to some extent does it. By practice in personal responsibility in little things, he can be led to wisdom in large ones. For the power to do great things in the moral world comes from doing the right in small things. It is not often that a man who knows that there is a right does the wrong. Men who do wrong are either ignorant that there is a right, or else they have failed in their orientation and look upon right as wrong. It is the clinching of good purposes with good actions that makes the man. This is the higher heredity that is not the gift of father or mother, but is the man's own work on himself.
The impression of realities is the basis of sound morals as well as of sound judgment. By adding near things to near, the child grows in knowledge. "Knowledge set in order" is science. Nature-study is the beginning of science. It is the science of the child. To the child training in methods of acquiring knowledge is more valuable than knowledge itself. In general, throughout life sound methods are more valuable than sound information. Self-direction is more important than innocence. The fool may be innocent. Only the sane and wise can be virtuous.
It is the function of science to find out the real nature of the universe. Its purpose is to eliminate the personal equation and the human equation in statements of truth. By methods of precision of thought and instruments of precision in observation, it seeks to make our knowledge of the small, the distant, the invisible, the mysterious as accurate as our knowledge of the common things men have handled for ages. It seeks to make our knowledge of common things exact and precise, that exactness and precision may be translated into action. The ultimate end of science, as well as its initial impulse, is the regulation of human conduct. To make right action possible and prevalent is the function of science. The "world as it is" is the province of science. In proportion as our actions conform to the conditions of the world as it is, do we find the world beautiful, glorious, divine. The truth of the "world as it is" must be the ultimate inspiration of art, poetry, and religion. The world as men have agreed to say it is, is quite another matter. The less our children hear of this, the less they will have to unlearn in their future development.
When a child is taken from nature to the schools, he is usually brought into an atmosphere of conventionality. Here he is not to do, but to imitate; not to see, nor to handle, nor to create, but to remember. He is, moreover, to remember not his own realities, but the written or spoken ideas of others. He is dragged through a wilderness of grammar, with thickets of diacritical marks, into the desert of metaphysics. He is taught to do right, not because right action is in the nature of things, the nature of himself and the things about him, but because he will be punished somehow if he does not.
He is given a medley of words without ideas. He is taught declensions and conjugations without number in his own and other tongues. He learns things easily by rote; so his teachers fill him with rote-learning. Hence, grammar and language have become stereotyped as teaching without a thought as to whether undigested words may be intellectual poison. And as the good heart depends on the good brain, undigested ideas become moral poison as well. No one can tell how much of the bad morals and worse manners of the conventional college boy of the past has been due to intellectual dyspepsia from undigested words.
In such manner the child is bound to lose his orientation as to the forces which surround him. If he does not recover it, he will spend his life in a world of unused fancies and realities. Nonsense will seem half truth, and his appreciation of truth will be vitiated by lack of clearness of definition—by its close relation to nonsense.
That this is no slight defect can be shown in every community. There is no intellectual craze so absurd as not to have a following among educated men and women. There is no scheme for the renovation of the social order so silly that educated men will not invest their money in it. There is no medical fraud so shameless that educated men will not give it their certificate. There is no nonsense so unscientific that men called educated will not accept it as science.
