Returning now to Thucydides, we have illustrated, as has been said, an utterly different plan and motive. Thucydides does indeed tell the story of the Peloponnesian War; tells it, moreover, with such wealth of detail as no other historian of antiquity exceeded, and few approached. But in addition to narrating the plain facts, Thucydides searches always for the motives. He gives us an insight into the causes of events as he conceives them. He is obviously thinking more of this phase of the subject than of the mere recital of the facts themselves. It is the philosophy of history, rather than the story of history, that appeals to him, and that he wishes to make patent to the reader.
Only two or three other writers of the entire classical period whose works have come down to us followed Thucydides with any considerable measure of success in this attempt to write history philosophically; the two most prominent exponents of this method being the Greek Polybius, who told the story of Rome’s rise to world power, and Tacitus, the famous author of the Roman Annals and of the earliest history of the German people. These three examples—Thucydides, Polybius, and Tacitus—stand out at once in refutation of a claim which might otherwise be made that philosophical, or, if one prefers, didactic, historical composition is essentially a modern product. But for these exceptions one might be disposed to make a sweeping generalisation to the effect that the old-time history was a collection of tales intended to entertain the reader, and that the strictly modern historical method aims at instruction rather than at entertainment. Such generalisations, however, assuming, as they do, that the entire trend of human thought has fundamentally changed within historical times, are sure to be faulty. Quite possibly it may be true to say that the earliest historians tended as a class to write entertaining narratives rather than philosophical histories; and to say, on the other hand, that nineteenth century historians as a class have reversed the order of motives: but it must not be forgotten that our judgment here is based upon a mere fragment of the entire output of ancient historians. We have already noticed, in another connection, that the names of some hundreds of Greek writers have been preserved to us solely through a single anthological collection or two; and now, speaking of the historical works, it must be remembered that a vast number of these have perished altogether. Whole companies of historians are known to us only by name, and there is every reason to suppose that considerable other companies that once existed and wrote works of greater or less importance have not left us even this memento. The scattered fragments of Greek historical works that have come down to us, dissociated from any considerable part of their original context, fill three large volumes of the famous Didot collection of Greek classics, as edited by K. O. Müller; some hundreds of authors being represented.
We have noted that all the predecessors of Herodotus were blotted out, chiefly, perhaps, by the excellence of the work of Herodotus himself. Similarly the entire histories of Alexander the Great, written by his associates and contemporaries and his successors of the ensuing century, have without exception perished utterly.
Doubtless the excellence of the work of Arrian, which summarised and attempted to harmonise the contents of the more important preceding histories of Alexander, was responsible for the final elimination of the latter. One can hardly refer too often to that intellectual gantlet of the middle ages, which all classical literature was called upon to pass, and from which only here and there a work emerged. It is almost pathetic to consider the number of works that made their way heroically almost through this gantlet, only to succumb just before achieving the goal. One knows, for example, that there was a work of Theopompus on later Grecian affairs, in fifty odd books, which was extant in the ninth century, as proved by the summary of its contents made then by a monk, but of which no single line is in existence to-day. Even the works that have come down to us in a less fragmentary condition have not usually been preserved entire in any single manuscript, but, as presented to us now, are patched together from various fragments, preserved often in widely separated collections. The explanation is that the copying of a manuscript of great length was a somewhat heroic task, and that hence the copyist would often content himself with excerpting a single book from a work which he would gladly have reproduced entire but for the labour involved.
The point of all this in our present connection is that we know the historians of antiquity very imperfectly, and that hence we are almost sure to misjudge them as a class when we attempt generalisations concerning them. In the very nature of the case, the historian who told a good story in a pleasing style stood a far better chance of being perpetuated through the efforts of copyists, than did the philosophical historian, however profound, who put forward his theories at the expense of the narrative proper. Making all due allowance for this, however, it can hardly be in doubt that the last century and a half has seen a remarkable development of the scientific spirit in its application to the work of the historian, and that the average historical work of the nineteenth century is philosophically on a far higher plane than the average historical work of antiquity. If we were to attempt to characterise the most recent phases of historical composition, we should, perhaps, not go far afield in saying that in regard to history-writing, as in regard to many other subjects, this is pre-eminently the age of specialists. In recent years no historical work could hope for any large measure of recognition among historians, unless it were based upon personal investigation of the most remote sources bearing upon the period that could be made accessible. The recent period has been pre-eminently a time of the searching out of obscure or forgotten records; the unburying of old letters and state papers; the delving into hitherto neglected archives; and the critical analysis of the conflicting statements of alleged authorities previously accessible.
The work began prominently—if any intellectual movement may properly be said to have an explicit beginning—with Gibbon and Niebuhr; it was continued by Grote and Mommsen and George Cornewall Lewis and Clinton, and the host of more recent workers, whose specific labours will claim our attention as we proceed. Naturally enough, since each generation of specialists builds upon the labours of all preceding generations, the work has become more and more minute and hair-splitting with each succeeding decade. Gibbon, specialist though he was, covered a period of a thousand years of European history, and left scarcely anything untouched that falls properly within that period. Niebuhr specialised on the few centuries of early Roman history, but his comprehensive view reached out also to Greece and to the Orient, and he was accounted a master over the whole range of ancient history. Mommsen’s efforts have followed the Roman Republic and Empire throughout the length and breadth of its wide domains, and over the whole period of its existence, as well as into all the ramifications of its political, commercial, and social life.
But there has been a tendency among most recent workers to confine their attention to a narrower field. Macaulay’s History of England attempts the really detailed history of only about seventeen years. Carlyle devotes six large volumes to the History of Frederick the Great, and such authorities as Freeman and Stubbs and Gardiner and Gairdner gave years of patient research to the investigation of single periods of English history. The obvious result of all this minute and laborious effort is the piling up of a mass of more or less incoördinate details as to the crude facts of history, which only the specialist in each particular field can hope to master, and the remoter bearings of which in their relations to world history are not always clearly appreciable. It is rarely given to the same mind to have a taste or a capacity at once for minute research and for broad and accurate generalisation. Therefore much of the work of the specialist, admirable in its kind, must still be regarded rather as crude material than as a finished product. It is the work of the world historian to attempt to mass this crude material, to visualise it in its relations to other similar masses, and to build with it a unified structure of history, in which each portion shall appear in its proper relations to all the rest.
