Thus is loaded with potential energy the universe of matter, generating life, mind, civilization, and hence we may conclude that whatever else it is, civilization is a force; that it is the sum of all the forces employed to drive humanity onward; that it acts on man as mechanical force acts on matter, attracting, repelling, pressing forward yet holding in equilibrium, and all under fixed and determined laws. * * * * * From all which it would appear that nothing is found in man that has not its counterpart in nature, and that all things that are related to man are related to each other; even immortal mind itself is not unlike that subtle force, inherent in, and working round every atom. In this respect physical science is the precursor of social science. Nature produces man; man in his earlier conception of nature, that is in his gods, reproduces himself; and later, his knowledge of intrinsic self depends upon his knowledge of extrinsic agencies, so that as the laws that govern external nature are better understood, the laws that govern society are more definitely determined. The conditions of human progress can be wrought into a science only by pursuing the same course that raises into a science any branch of knowledge; that is, by collecting, classifying, and comparing facts, and therefrom discovering laws. Society must be studied as chemistry is studied; it must be analyzed, and its component parts--the solubilities, interactions, and crystallizations of religions, governments and fashions, ascertained. As in the earlier contemplations of physical nature, the action of the elements was deemed fortuitous, so in a superficial survey of society, all events appear to happen by chance; but on deeper investigation, in society as in physics, events apparently fortuitous, may be reduced to immutable law. To this end the life of mankind on the globe must be regarded as the life of one man, successions of societies as successions of days in that life; for the activities of nations are but the sum of the activities of the individual members thereof. [Sidenote: PHYSICAL LAWS AND SOCIAL LAWS.] We have seen that man's organism, as far as it may be brought under exact observation, is governed by the same processes that govern elemental principles in inorganic nature. The will of man attempting to exert itself in antagonism to these laws of nature is wholly ineffectual. We are all conscious of a will, conscious of a certain freedom in the exercise of our will, but wholly unconscious as to the line of separation between volition and environment. Part of our actions arise from fixed necessity, part are the result of free will. Statistics, as they are accumulated and arranged, tend more and more to show that by far the greater part of human actions are not under individual control, and that the actions of masses are, in the main, wholly beyond the province of the human will.
