It seems plainly apparent, then, that neither the principle of individualism nor the principle of societism can be taken as an infallible guide for determining the control of our industry. It would be as manifestly unwise to take a step toward abolishing existing societism by placing our postal department under the control of a private company, as it would be to make a move toward abolishing individualism by having the government assume the management of all the farms in the country. Both of these principles are necessary. There is, indeed, a marked tendency toward an increased reliance on the principle of societism as civilization progresses and our life becomes necessarily more intense and complex. A community of plain farmers, isolated from each other, can live their individual lives about as they please, without any interference of the government becoming necessary to protect the rights of each man from infringement by his neighbors. But the resident in a large village must submit to certain restrictions for the common good. He must not carry on any kind of business likely to become a public nuisance. His cattle may not graze in the streets. He must give part of his earnings toward maintaining a water supply for a protection against fire. The citizen of a great city is subject to far more restrictions. The government assumes the control of education, charities, the care of the public health, the drainage of the streets, the collection of offal, and a multitude of other duties which in a less intense civilization each family performs for itself. The advance in science and the arts, too, has brought about a revolution whose effect we must recognize. A hundred years ago almost every community, and to a large degree every family, was industrially almost independent of every other, as we have already shown. To-day each man relies on a million others to supply him with the commonest necessaries of life. The armored knight was proof against all foes, save the few antagonists similarly clad. To-day my life is dependent on the fidelity and vigilance of ten thousand men, and every man I meet has me in his power. Given the malignant will and fiendish cunning necessary, and one single man can kill a thousand human beings and destroy a million dollars at a blow. To sum up, each advance in civilization makes men more dependent upon each other, and increases the advantage and necessity of having industries most important to the common welfare controlled by society as a whole instead of by individuals.
