The human worker, whether a captain of industry or in the ranks, who puts his personal safety and advantage before that of his country is exactly the same traitor and coward that the officer or private in the army would be who did the same thing. He does not know it, we do not know it, therefore no odium attaches to these public offenders. But the mischief they do is apparent in every branch of our economic processes. We have seen that human production is checked in amount by our lack of knowledge. It is injured in kind from the same cause. Normal production has an evolution of its own. Follow the development of any one trade, and you will see as natural a growth as in a physical organ, marred of course by our errors, but there under all. Take the building trades as an example. At the beginning we find primitive man enlarging a cave somewhat, or, lacking that retreat, putting up some shelter of boughs to screen him from the wind and rain, or spreading a hide for the same purpose. The act, repeated, develops skill, and the mind, dwelling over and over on the same problem, develops too, and sees better ways of accomplishment. The shelter of hide becomes the teepee or wigwam, and, cloth superseding leather, the tent in all its forms; but its growth is limited by mechanical conditions. The shelter of boughs is more open to improvement; and evolves slowly into hut, cabin, house. The materials used depending on the environment, the Eskimo builds of ice, the Chaldean of clay, and, slowly, by proof of superiority, stone was used wherever found. The principle of specialisation acting steadily upon this widening current of functional ability, we have now that group of allied trades required to construct for modern man the material form in which he lives and works—without which he cannot live and work. A genealogical tree could be made, showing just where each branch diverged, the workers in wood, clay, and stone dividing early; the gradual appearance of the system of pipes and conduits which vitalise a house; the development of windows in all forms, of doors and their particular line of improvement, of interior finish, from daubed mud to artistic decoration; and so on and so on, until we have now the house which stands knit to the city by waste pipe, water pipe, gas pipe, and electric wire; a house which represents the slow fruition of a thousand centuries, the contributed intelligence and skill of a million men. The evolution of this “social form” is as natural and orderly as the evolution of any physical form. To the men through whom it grew the whole course should have been a pleasure and a pride, and in large measure it has been, in spite of all our misbeliefs.
