Looking back to that first visit to Edison, the first of perhaps a score that I have had occasion to make him in the last fifteen years, what impressed me most was the immensity of the field in which he takes an interest. Ask Edison what he thinks will be the next step in the development of the sewing-machine, or the telescope, the microscope, the steam-engine, the electric-motor, the reaping-machine, or any device by which man accomplishes much work in little time, and invariably it will be found that he has some novel ideas upon the subject, perhaps fanciful in the extreme, but practical enough to show that he has pondered the matter. He shares the opinion of the gentleman who insists that whatever is is wrong, but only to this extent: that whatever is might be better. Authority means nothing to him; he must test for himself. For instance, it is well known that he rejects the Newtonian theory in part and holds that motion is an inherent property of matter; that it pushes, finding its way in the direction of least resistance, and is not pulled or attracted. "It seems to me," he said once, "that every atom is possessed by a certain amount of primitive intelligence. Look at the thousand ways in which atoms of hydrogen combine with those of other elements, forming the most diverse substances. Do you mean to say that they do this without intelligence? Atoms in harmonious and useful relation assume beautiful or interesting shapes and colors, or give forth a pleasant perfume, as if expressing their satisfaction. In sickness, death, decomposition, or filth the disagreement of the component atoms immediately makes itself felt by bad odors." It is partly due to this belief in the sensibility of atoms that Edison attributes his faith in an intelligent Creator. [Illustration]
