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.
