Physical geography also indicates, not only a state of preparation for man, but also a special adaptation of the fixed forms of the earth's surface for securing the perfect development of man according to the Divine ideal. And as the land which man inhabits, the food he eats, the air he breathes, the mountains and rivers and seas which are his neighbors, the skies that overshadow him, the diversities of climate to which he is subject, and indeed all physical conditions, exert a powerful influence upon his tastes, pursuits, habits, and character—we may presume that not only are all these conditions predetermined by God, but continually under his control and supervision.

The distribution of terrestrial areas—the continents, islands, and seas; the disposition of the climate, soil, and vegetation, apparently accidental, have played an important part in the moral history of our race. There is a close relation between nature and history, between the earth and man. The soul of man is distinct from, but not totally independent of the body and of external physical conditions. To deny this would be to reject all the lessons of experience. The relation of man to nature is not, however, a relation of cause and effect, but, as Cousin remarks, "Man and nature are two great effects which, coming from the same cause, bear the same characteristics, so that the earth and he who inhabits it, man and nature, are in perfect harmony."[374] "A living God," says Ritter, "is at the head of the physical and moral world."[375] The earth was created for man, not simply to be a dwelling-place, but a school-house[376]—made to be a theatre for the education, the development, and the perfection of the human race. And as the moral and intellectual culture of the child is materially affected by the physical conditions with which he is surrounded, and as these are consequently the subject of care and forethought on the part of the intelligent and prudent parent and teacher, so the external physical conditions of a nation exert a powerful influence on its intellectual and moral development, and therefore must be presumed to be the subject of forethought and providence on the part of God, "the Father of the families of all the earth." God has superintended the peopling of the earth, the dispersions and migrations of nations, guiding the footsteps of the "covenant, educating, and missionary nations" to those countries best adapted to their highest development. In a word, He has ordained the progress of empire and the course of civilization.

Thus nature and history are the two great factors of Divine providence; in their relations and harmonies we have a revelation of the purposes and plans of God.[377]

That geographical conditions do exert a powerful influence on the character of nations can not be denied. "The bodily constitution of a people, their temperament, modes of life, habitations, customs, languages, and even religious opinions have been formed or modified under the influence of that magic circle of nature which surrounds them, and which so powerfully affects what is individual in national character." So that, could we fully grasp all the characteristics of a country—its position, configuration, climate, scenery, and natural products—we could, with tolerable accuracy, determine what are the characteristics of the people who inhabit it. We have discussed this topic at some length in "Christianity and Greek Philosophy," and shall here simply recall such of the general facts and principles as may be needed for a clear understanding of the present discussion.

1. The habits and characteristics of the dwellers in the Temperate Zone differ widely from those of the dwellers in the Torrid Zone. This is an obvious fact; and the causes of this difference are equally obvious to the observant mind. In the tropical regions the powers of vegetable and animal life are stimulated to the highest degree, and here nature displays her fullest energy, her greatest variety, and her richest splendors. Excessive heat enfeebles and enervates man. It induces lassitude, dreaminess, effeminacy, and tempts to quietude and indolence. Where nature pours her fullness into the lap of ease, forethought and providence are little needed. Here is none of that struggle for existence which awakens sagacity and develops industry. Nothing calls man to that effort for the conquest of nature by which the intellect is aroused and the reasoning faculties are developed. Consequently the mere life of the body, the powers of the physical nature of man, overmaster the faculties of the mind. The instincts predominate over the reason. Simple spontaneity of thought is manifested, but little or no analytic reflection. Feeling, imagination, sentiment, predominate over intellect, reason, and science. In a temperate climate all is reversed. The alternations of heat and cold render man more vigorous, and impart more physical tone. Where there is less profusion and lavishment of nature's gifts, there is more room and motive for industry. The change of seasons, and an annual period of dormancy, demand forethought and prudence. The preservation of life demands, not merely physical toil, but some degree of contrivance, and, indeed, the vigorous exertion of the intellectual powers. And here, though nature is not prodigal of her gifts, she grants to industry and skill something more than the bare necessities of life. She allows man to lay up a store for the future, and furnishes some leisure for the culture of the mind. The active powers of man, his reason and judgment, rule his instincts, and control, more or less, his appetites and emotions. Here man becomes a careful observer of events; he treasures up the results of experience, compares one fact with another, notes their relations, and makes new experiments to test his conclusions. Thus science has its birth in the Temperate Zone.[378]

2. There is a marked difference between the mental habits and modes of thought of the peoples who dwell in the interior of an immense continent and those who dwell on the margin of the sea. Vast continents, unbroken by lakes and inland seas, and extended plains where broad deserts and high mountain ranges separate the populations, are the seats of immobility. The inhabitants are isolated from the rest of the world, and excluded from a stimulating and profitable intercourse with the nations of the earth. They have comparatively no navigation, their commerce is limited to the bare necessities of life, and there are no inducements to movement, to travel, and to enterprise. Society is therefore stationary, as in China; the habits, manners, and usages of social and civil life remain as they were two thousand years ago. Infolded and imprisoned within the overwhelming vastness and illimitable sway of nature, man is almost unconscious of his freedom and personality. He surrenders himself to the disposal of a mysterious "fate," and yields readily to the absolute control of rulers who are regarded as of supernatural origin and endowed with superhuman powers. The forms of government remain unchanged from age to age, and the state is the reign of fixed and inexorable laws—"The laws of the Medes and Persians are unalterable." The rights of the person are scarcely recognized, and the individual is lost in the mass.

Extended border-lands on the margin of great rivers and inland seas are, on the contrary, the theatre of movement, activity, and life. Here man is set free from the bondage imposed by the overpowering magnitude and vastness of continental and oceanic forms. Here industry is not stationary, but progressive; and commerce thrives because the rivers and inland seas furnish the means of easy transit, and the opportunity for a free interchange of commodities. Along with the exchange of commodities there will be an exchange of ideas, because ideas flow along the channels of commerce. Here also the arts will be cultivated, first for purposes of gain, and subsequently for the gratification of taste. And, where there is freedom of movement, where there is creative industry, where nature is subjugated by man, the idea of personal liberty will be developed, and the rights of the individual will be regarded. These ideas of personal liberty and rights will become incorporated with the laws and institutions of society, and the government will tend toward a democracy. Finally, this freedom of movement and action will engender freedom of thought. Reflection will commence, the speculative and critical spirit will arise, and philosophy will be born.[379]

3. There is also an acknowledged difference between the mental character of the inhabitants of a bright and sunny climate who breathe an elastic atmosphere, and are surrounded by the most inspiring scenery, and that of the people who dwell under a gray and sombre sky, and daily look upon the more stern and rugged aspects of nature. The dwellers in the former climate are ardent, vivacious, and mercurial; the inhabitants of the latter are slow, deliberate, persistent, and conservative. One nation will be speculative, enamored of plausible hypotheses, and prone to hasty and brilliant generalization; the other will be practical, intolerant of hypotheses, and clamorous for facts and logical inferences from facts. In the former climate the fine arts will be enthusiastically cultivated, and elegance and taste, and all that is graceful in sentiment and action, will find a congenial home; in the latter, the exact sciences and the useful arts will be cultivated with persistence and zeal. Under the former conditions, a religion of poetry, of sentiment, of artistic display and imposing ceremonial, will sway the popular mind; under the latter, a religion of personal duty and purity, of social righteousness, of active beneficence, and of universal charity, will command respect.

These principles constitute what may be designated the statics of history—the more or less stable and permanent conditions under which the living forces of humanity are developed.

The dynamics of history are the fundamental powers and rational ideas of human nature. There are certain primary ideas of the reason which are revealed in the universal consciousness of our race under the conditions of experience—the exterior conditions of physical nature and sensational life. Such are the ideas of substance and cause, of unity and infinity, which govern all the processes of discursive thought, and lead us to the recognition of the uncreated and unconditioned Being; such the ideas of right, of duty, of accountability, and of retribution which regulate all the conceptions we form of our relations to other moral beings, and constitute morality; such the ideas of order, proportion, and harmony which preside in the realm of art, and constitute the beau-ideal of æsthetics; such the ideas of God, the soul, and immortality which rule in the domain of religion, and constitute man a religious being. In addition to these, there are the powers of observation, of abstraction, of generalization, of inference, the capacity of symbolic conception and expression, the faculty of creative imagination, the powers of invention, of foresight, and of scientific prevision. These are the living forces of humanity, fundamentally the same under all circumstances, but modified in their intensity and development by geographical, climatal, and scenic conditions. The providential adjustment and harmonious relation of the exterior conditions with the inherent powers of humanity is the problem of history.
