This materialistic belief regards the human body as a self-sufficient machine whose brain generates thought. But the savage has a completely evolved physical body with eyes, ears and other organs like our own. His brain under the microscope shows no trace of difference in its material constitution from the brain of civilized man. Indeed, his physical body is not only as complete a machine as ours but is likely to be materially sounder. Why, then, if the brain produces thought, does not this savage produce the thoughts of a philosopher? If there is no directing soul back of the brain, why the marvelous difference in the product of the two brains? Materialists go too far in the assumption that they can explain the phenomena of life. They can talk learnedly about it but they must stop short of the source of life. Everything about anatomy and physiology they know, but the life that flows through the human machine remains unexplained. They can trace the circulation of the blood from the heart through the arteries, from the arteries across to the veins, from the veins back to the heart, but the greatest mind the race has produced cannot say what makes the heart beat. Life has not been explained and cannot be explained from the materialist's viewpoint. Every human being is a miracle. A fingernail is a mystery of evolution. It is formed from the same food that makes the flesh and it will continue to be formed regardless of the variety or quality of the food. Why do certain particles become flesh or nails? Who can draw the division line between them? With marvelous instruments and wondrous skill science has explored and mapped and charted the "tabernacle of clay," but it cannot throw a single ray of light upon the intelligence that animates it. Materialism fails sadly enough in that direction, but still worse as a satisfactory interpretation of the panorama of the life about us. It is a philosophy of the gloomiest fatalism. It holds that we simply chance to be that which we are; that we are what we are merely because of fortuitous chemical and mechanical combinations. Had the combinations chanced to be something different we should not be in existence. Chance is the king of the materialist's world.
