The new age is the age of style. The same spirit of exclusive attention to form which made Euripides often, like Swinburne, prefer music to meaning and melody to morality, which gave to the later Greek statues that refined effeminacy, that overstrained gracefulness of attitude, was felt in the sphere of history. The rules laid down for historical composition are those relating to the æsthetic value of digressions, the legality of employing more than one metaphor in the same sentence, and the like; and historians are ranked not by their power of estimating evidence but by the goodness of the Greek they write.
I must note also the important influence on literature exercised by Alexander the Great; for while his travels encouraged the more accurate research of geography, the very splendour of his achievements seems to have brought history again into the sphere of romance. The appearance of all great men in the world is followed invariably by the rise of that mythopœic spirit and that tendency to look for the marvellous, which is so fatal to true historical criticism. An Alexander, a Napoleon, a Francis of Assisi and a Mahomet are thought to be outside the limiting conditions of rational law, just as comets were supposed to be not very long ago. While the founding of that city of Alexandria, in which Western and Eastern thought met with such strange result to both, diverted the critical tendencies of the Greek spirit into questions of grammar, philology and the like, the narrow, artificial atmosphere of that University town (as we may call it) was fatal to the development of that independent and speculative spirit of research which strikes out new methods of inquiry, of which historical criticism is one.
The Alexandrines combined a great love of learning with an ignorance of the true principles of research, an enthusiastic spirit for accumulating materials with a wonderful incapacity to use them. Not among the hot sands of Egypt, or the Sophists of Athens, but from the very heart of Greece rises the man of genius on whose influence in the evolution of the philosophy of history I have a short time ago dwelt. Born in the serene and pure air of the clear uplands of Arcadia, Polybius may be said to reproduce in his work the character of the place which gave him birth. For, of all the historians—I do not say of antiquity but of all time—none is more rationalistic than he, none more free from any belief in the ‘visions and omens, the monstrous legends, the grovelling superstitions and unmanly craving for the supernatural’ (δεισιδαιμουνιας αyεννους και τερατειας yυναικωδους [{197a}]) which he is compelled to notice himself as the characteristics of some of the historians who preceded him. Fortunate in the land which bore him, he was no less blessed in the wondrous time of his birth. For, representing in himself the spiritual supremacy of the Greek intellect and allied in bonds of chivalrous friendship to the world-conqueror of his day, he seems led as it were by the hand of Fate ‘to comprehend,’ as has been said, ‘more clearly than the Romans themselves the historical position of Rome,’ and to discern with greater insight than all other men could those two great resultants of ancient civilisation, the material empire of the city of the seven hills, and the intellectual sovereignty of Hellas.
Before his own day, he says, [{197b}] the events of the world were unconnected and separate and the histories confined to particular countries. Now, for the first time the universal empire of the Romans rendered a universal history possible. [{198a}] This, then, is the august motive of his work: to trace the gradual rise of this Italian city from the day when the first legion crossed the narrow strait of Messina and landed on the fertile fields of Sicily to the time when Corinth in the East and Carthage in the West fell before the resistless wave of empire and the eagles of Rome passed on the wings of universal victory from Calpè and the Pillars of Hercules to Syria and the Nile. At the same time he recognised that the scheme of Rome’s empire was worked out under the ægis of God’s will. [{198b}] For, as one of the Middle Age scribes most truly says, the τυχη of Polybius is that power which we Christians call God; the second aim, as one may call it, of his history is to point out the rational and human and natural causes which brought this result, distinguishing, as we should say, between God’s mediate and immediate government of the world.
With any direct intervention of God in the normal development of Man, he will have nothing to do: still less with any idea of chance as a factor in the phenomena of life. Chance and miracles, he says, are mere expressions for our ignorance of rational causes. The spirit of rationalism which we recognised in Herodotus as a vague uncertain attitude and which appears in Thucydides as a consistent attitude of mind never argued about or even explained, is by Polybius analysed and formulated as the great instrument of historical research.
Herodotus, while believing on principle in the supernatural, yet was sceptical at times. Thucydides simply ignored the supernatural. He did not discuss it, but he annihilated it by explaining history without it. Polybius enters at length into the whole question and explains its origin and the method of treating it. Herodotus would have believed in Scipio’s dream. Thucydides would have ignored it entirely. Polybius explains it. He is the culmination of the rational progression of Dialectic. ‘Nothing,’ he says, ‘shows a foolish mind more than the attempt to account for any phenomena on the principle of chance or supernatural intervention. History is a search for rational causes, and there is nothing in the world—even those phenomena which seem to us the most remote from law and improbable—which is not the logical and inevitable result of certain rational antecedents.’
Some things, of course, are to be rejected a priori without entering into the subject: ‘As regards such miracles,’ he says, [{199}] ‘as that on a certain statue of Artemis rain or snow never falls though the statue stands in the open air, or that those who enter God’s shrine in Arcadia lose their natural shadows, I cannot really be expected to argue upon the subject. For these things are not only utterly improbable but absolutely impossible.’
‘For us to argue reasonably on an acknowledged absurdity is as vain a task as trying to catch water in a sieve; it is really to admit the possibility of the supernatural, which is the very point at issue.’
What Polybius felt was that to admit the possibility of a miracle is to annihilate the possibility of history: for just as scientific and chemical experiments would be either impossible or useless if exposed to the chance of continued interference on the part of some foreign body, so the laws and principles which govern history, the causes of phenomena, the evolution of progress, the whole science, in a word, of man’s dealings with his own race and with nature, will remain a sealed book to him who admits the possibility of extra-natural interference.
The stories of miracles, then, are to be rejected on a priori rational grounds, but in the case of events which we know to have happened the scientific historian will not rest till he has discovered their natural causes which, for instance, in the case of the wonderful rise of the Roman Empire—the most marvellous thing, Polybius says, which God ever brought about [{200a}]—are to be found in the excellence of their constitution (τη ιδιοτητι της πολιτειας), the wisdom of their advisers, their splendid military arrangements, and their superstition (τη δεισιδαιμονια). For while Polybius regarded the revealed religion as, of course, objective reality of truth, [{200b}] he laid great stress on its moral subjective influence, going, in one passage on the subject, even so far as almost to excuse the introduction of the supernatural in very small quantities into history on account of the extremely good effect it would have on pious people.
