Section Ii.--Unity of Origin

This unity of character is very largely due to continuous descent from a common cultural ancestor. The civilization of the West is fundamentally one not because the peoples of the West are one racially. They are not so. They comprise every branch of the Aryan family and a considerable admixture of quite other stocks. Their civilization owes its common characteristics mainly to a common origin and continued interaction. That is why it is in the mass a community of ideas, for ideas pass from man to man and from nation to nation more readily than institutions, more readily far than character, more readily perhaps than anything except material goods. In the realm of ideas Western civilization forms a single commonwealth of informal but of exceeding democratic constitution. This freedom, indeed, it owes in large measure to its international character, for there are constantly arising local and temporary dictators, arbiters of fashion in the ideas of politics, philosophy, and even of science. Within a narrow circle such a dictator often has it all his own way, but it is seldom that he can maintain a prolonged ascendancy throughout the international commonwealth unless there is some pretty solid foundation for his doctrine.

This commonwealth has its foundations in the past. It derives in the first instance from the unity of mediaeval Christendom, where it enjoyed the advantage of a common language of learning, the gradual loss of which is imperfectly compensated by the possession of two or three modern languages alone by the educated man of the present day. Through mediaeval Christendom and through the Arabic schools, which can hardly be regarded as a part of Western civilization but in the Middle Ages were rather its teachers, it derives from the Greco-Roman world, and through the Greco-Roman world from the Greeks themselves. The Greeks in their turn were aware that they owed the rudiments of their science to the ancient civilizations of the Nile and the Euphrates. Thus in the intellectual world there is a continuity stretching back six thousand years or more to the beginnings of recorded civilization. More than once the continuity is nearly broken, but some strand is always preserved, and it is in this continuity in the world of ideas that we get the main evidence of such progress as human history reveals.

The foundations of material civilization were laid in Egypt and in Babylonia, where the progress made in agriculture and the industrial arts implies a considerable body of empirical knowledge of physics and chemistry at an early date. We have Egyptian textbooks of arithmetic dating from the eighteenth and perhaps from the twelfth dynasty. We have texts dealing with the rudiments of geometry. Empirical chemistry appears to be of Egyptian origin, the word itself is referred to the Egyptian term for black earth--and to have passed to the Arabs, who made it into a quantitative science, without greatly interesting the scientific mind of Greece. Careful astronomical records extending over thousands of years were kept both in Egypt and Babylonia, and upon them a considerable body of astronomical knowledge was built up. But there is no evidence of a scientific interest detached at once from theology and industry. In theology itself Egyptian learning early became dissatisfied with the popular deities, and sought for a unity of the godhead either in some one supreme deity such as the sun or, more often, in a mystical identification of all the gods as so many incarnations or impersonations of a single principle. But though these and kindred speculations were not without influence on Greek thought, the entire achievement of Egypt in this direction, so far as known to us, was of little importance as compared with that of other oriental civilizations.

Thus without underestimating a debt which the Greeks themselves acknowledged, it remains true to regard science and philosophy alike as in essence an original creation of the Greek genius. What grew up in Greece during the sixth and fifth centuries B.C. was the spirit of disinterested inquiry proceeding on rational methods. By the term disinterested I mean detached from ulterior objects. Geometry for the Greek was something more than the art of land measurement, astronomy something more than a means of regulating the calendar or foretelling an eclipse. It was a study of the nature of the heavens, an attempt to penetrate the construction of the material universe. So with geometry. It might begin as an investigation of the relations of particular triangles, squares, and oblongs, but it developed into an attempt to grasp the nature of space relations and to understand them as depending on simple common principles. This is to say that in the hands of the Greeks these subjects first became sciences. But a still greater subject also became in their hands matter for disinterested rational inquiry. They developed what Aristotle called the science of Reality, or, as we call it, Philosophy--the attempt to approach by the rational criticism of experience the problem of the nature and origin of the universe and of man's place therein. They propounded the fundamental questions which still occupy the highest intellects of mankind. They laid the foundations of method and bequeathed to Europe the terminology which all exact thinking requires. Even when we speak of method we are using an Aristotelian term, and when we distinguish one subject from another we are employing the Latin translation of the word which Aristotle introduced. In a word, modern thought, scientific and philosophic alike, has a unitary origin. It is derived from the Greek.

The mode of this derivation is not simple, and would require considerable space to examine in detail. In outline it must suffice to say that the Greek culture was spread over the Eastern Mediterranean through the conquests of Alexander, and that as its capital Alexandria gradually replaced Athens. It flowed westward with the Roman conquests, when, as the Roman poet said, captured Greece took captive her barbarous conqueror and introduced the arts into rustic Latium. It shared in the general decline which accompanied the rebarbarization and final collapse of the Roman Empire. But now occurred a division in the stream of historic tendency. The fortunes of East and West were separated. The Western Empire was overrun by Germanic tribes, and after the sixth century the tradition of the old culture was maintained for the most part in the monasteries. Greek was forgotten in the West. Greek authors were known only in Latin translations, and science and philosophy came to a standstill. In the East the Mohammedan conquests brought the Arabs into touch with Greek learning. They preserved the tradition and extended the work, and it was the contact with Arabic culture through the crusades which initiated the first renaissance in the West in the twelfth century. There followed the epoch of the great mediaeval systems, the rediscovery of Aristotle and the attempt to fuse the Christian faith with the Aristotelian system. The later Middle Age was the period at which Western civilization was most distinctly a cultural unit, the scene of a great attempt to unify all the aspects of life, the religious, the philosophic, the political, on the basis of a religious faith made articulate and systematic with the aid of Greek philosophy, speaking the Latin tongue as the common possession of all educated men.

The paradox of thought is that while unity is its ideal, freedom is its necessary condition, and endless divergence the inevitable consequence. There could not be much thinking about matters of faith without heresy, nor about matters of politics without disaffection, rebellions and new political grouping. Heresy and schism broke up the mediaeval unity and reinforced the political tendencies making towards the modern state system. The rise of modern literature displaced the classics from their unique position as literary models. After the seventeenth century the habit of writing in the vernacular tended more and more to oust Latinity, and culture in each country began to assume more of a distinctively national character. Specific national characteristics began to appear in science and philosophy as well as in literature and education, and a large part of the history of modern thought depends on the partial independence on the one hand and the frequent interactions on the other of these centres.
