II. History and the Earth

Let us define history, in its troublesome duplexity, as the events or record of the past. Human history is a brief spot in space, and its first lesson is modesty. At any moment a comet may come too close to the earth and set our little globe turning topsy-turvy in a hectic course, or choke its men and fleas with fumes or heat; or a fragment of the smiling sun may slip off tangentially—as some think our planet did a few astronomic moments ago—and fall upon us in a wild embrace ending all grief and pain. We accept these possibilities in our stride, and retort to the cosmos in the words of Pascal: “When the universe has crushed him man will still be nobler than that which kills him, because he knows that he is dying, and of its victory the universe knows nothing.”7

History is subject to geology. Every day the sea encroaches somewhere upon the land, or the land upon the sea; cities disappear under the water, and sunken cathedrals ring their melancholy bells. Mountains rise and fall in the rhythm of emergence and erosion; rivers swell and flood, or dry up, or change their course; valleys become deserts, and isthmuses become straits. To the geologic eye all the surface of the earth is a fluid form, and man moves upon it as insecurely as Peter walking on the waves to Christ.

Climate no longer controls us as severely as Montesquieu and Buckle supposed, but it limits us. Man’s ingenuity often overcomes geological handicaps: he can irrigate deserts and air-condition the Sahara; he can level or surmount mountains and terrace the hills with vines; he can build a floating city to cross the ocean, or gigantic birds to navigate the sky. But a tornado can ruin in an hour the city that took a century to build; an iceberg can overturn or bisect the floating palace and send a thousand merrymakers gurgling to the Great Certainty. Let rain become too rare, and civilization disappears under sand, as in Central Asia; let it fall too furiously, and civilization will be choked with jungle, as in Central America. Let the thermal average rise by twenty degrees in our thriving zones, and we should probably relapse into lethargic savagery. In a semitropical climate a nation of half a billion souls may breed like ants, but enervating heat may subject it to repeated conquest by warriors from more stimulating habitats. Generations of men establish a growing mastery over the earth, but they are destined to become fossils in its soil.

Geography is the matrix of history, its nourishing mother and disciplining home. Its rivers, lakes, oases, and oceans draw settlers to their shores, for water is the life of organisms and towns, and offers inexpensive roads for transport and trade. Egypt was “the gift of the Nile,” and Mesopotamia built successive civilizations “between the rivers” and along their effluent canals. India was the daughter of the Indus, the Brahmaputra and the Ganges; China owed its life and sorrows to the great rivers that (like ourselves) often wandered from their proper beds and fertilized the neighborhood with their overflow. Italy adorned the valleys of the Tiber, the Arno, and the Po. Austria grew along the Danube, Germany along the Elbe and the Rhine, France along the Rhone, the Loire, and the Seine. Petra and Palmyra were nourished by oases in the desert.

When the Greeks grew too numerous for their boundaries, they founded colonies along the Mediterranean (“like frogs around a pond,” said Plato8) and along the Euxine, or Black, Sea. For two thousand years—from the battle of Salamis (480 B.C.) to the defeat of the Spanish Armada (1588)—the northern and southern shores of the Mediterranean were the rival seats of the white man’s ascendancy. But in and after 1492 the voyages of Columbus and Vasco da Gama invited men to brave the oceans; the sovereignty of the Mediterranean was challenged; Genoa, Pisa, Florence, Venice declined; the Renaissance began to fade; the Atlantic nations rose, and finally spread their suzerainty over half the world. “Westward the course of empire takes its way,” wrote George Berkeley about 1730. Will it continue across the Pacific, exporting European and American industrial and commercial techniques to China, as formerly to Japan? Will Oriental fertility, working with the latest Occidental technology, bring the decline of the West?

The development of the airplane will again alter the map of civilization. Trade routes will follow less and less the rivers and seas; men and goods will be flown more and more directly to their goal. Countries like England and France will lose the commercial advantage of abundant coast lines conveniently indented; countries like Russia, China, and Brazil, which were hampered by the excess of their land mass over their coasts, will cancel part of that handicap by taking to the air. Coastal cities will derive less of their wealth from the clumsy business of transferring goods from ship to train or from train to ship. When sea power finally gives place to air power in transport and war, we shall have seen one of the basic revolutions in history.

The influence of geographic factors diminishes as technology grows. The character and contour of a terrain may offer opportunities for agriculture, mining, or trade, but only the imagination and initiative of leaders, and the hardy industry of followers, can transform the possibilities into fact; and only a similar combination (as in Israel today) can make a culture take form over a thousand natural obstacles. Man, not the earth, makes civilization.
