The tool is but dead matter; the productive efficiency is in the vital energy of the intelligent laborer. The most complicated and ingenious tool ever made is useless without the operator. It is as helpless as the wire without the electric current; as helpless as the body without its life, for the body is but man's tool, preserved, and kept efficient, and made productive, by the living energy alone. Tools are but the reaching out of the vital energy beyond the body. Tools are but the means, invented and constructed, by which the man can overcome his physical limitations and accomplish wonders, the impossible to a creature wanting in his intelligence. These glasses enable dim eyes to see clearly. There is no ability in the glasses to see; they would be of no use on blind eyes. I see, these spectacles cannot see. Enlarge and so place these lenses that I can see bacteria, or the mountains of the moon, yet this microscope or this telescope has no more life nor sight than this single lens. I, with it, see the minute creation or examine the distant planet. It is but the extension of my eye. This pen and paper and this book are but the means by which I reach and reason with my fellow-men. They are but my tools to convey my thought. I am reasoning with you, not this paper and ink. My hand is the natural tool with which I labor. I may work in the garden and plant the seed and destroy the weeds with my hand alone, and there is no dispute but that I do the work. I take a small weeder in my hand and greatly increase my efficiency. I take a hoe and reach out further and greatly add to my efficiency. I am the efficient agent. There is no power in the weeder or the hoe. I take my plow, as my tool, and I tear up the soil and prepare it for my harvest. I take the complicated harvester and gather it into my barn. In every part of that process the tool is but the reaching out of my energy beyond my body. There is no place where that tool becomes vitalized and productive. I am a porter, I carry packages in my hands. To increase my efficiency I build me a cart, and smooth a roadway, by which I am able to carry more and heavier packages with ease. I construct a roadway across the continent, and with the power which I employ I carry the commerce of the nation. I build ships and direct them from continent to continent and handle the commerce of the world. Now there is no place from this simple carriage in the hand, to the complicated and stupendous system of transportation, where the tool is not wholly dependent on the vital intelligent energy. When the vital principle leaves this body, then hands, eyes and the whole body is helpless. Withdraw the vital energy from these means by which man extends his power beyond the body, and all the implements of agriculture will not produce a harvest, and the wheels of commerce on land and sea would instantly stop.
