[1] Annual address of the president of the American Historical Association delivered at Boston, December 27, 1912.

There was a time—we see it in the marvellous dawn of Hellenic life—when history was distinguished neither from poetry, from mythology, nor from the first dim beginnings of science. There was a more recent time, at the opening of Rome’s brief period of literary splendor, when poetry was accepted by a great scientific philosopher as the appropriate vehicle for teaching the lessons of science and philosophy. There was a more recent time still—the time of Holland’s leadership in arms and arts—when one of the two or three greatest world painters put his genius at the service of anatomists.

In each case the steady growth of specialization has rendered such combination now impossible. Virgil left history to Livy; and when Tacitus had become possible Lucan was a rather absurd anachronism. The elder Darwin, when he endeavored to combine the functions of scientist and poet, may have thought of Lucretius as a model; but the great Darwin was incapable of such a mistake. The surgeons of to-day would prefer the services of a good photographer to those of Rembrandt—even were those of Rembrandt available. No one would now dream of combining the history of the Trojan War with a poem on the wrath of Achilles. Beowulf’s feats against the witch who dwelt under the water would not now be mentioned in the same matter-of-fact way that a Frisian or Frankish raid is mentioned. We are long past the stage when we would accept as parts of the same epic Siegfried’s triumphs over dwarf and dragon, and even a distorted memory of the historic Hunnish king in whose feast-hall the Burgundian heroes held their last revel and made their death fight. We read of the loves of the Hound of Muirthemne and Emer the Fair without attributing to the chariot-riding heroes who “fought over the ears of their horses” and to their fierce lady-loves more than a symbolic reality. The Roland of the Norman trouvères, the Roland who blew the ivory horn at Roncesvalles, is to our minds wholly distinct from the actual Warden of the Marches who fell in a rear-guard skirmish with the Pyrenean Basques.

As regards philosophy, as distinguished from material science and from history, the specialization has been incomplete. Poetry is still used as a vehicle for the teaching of philosophy. Goethe was as profound a thinker as Kant. He has influenced the thought of mankind far more deeply than Kant because he was also a great poet. Robert Browning was a real philosopher, and his writings have had a hundredfold the circulation and the effect of those of any similar philosopher who wrote in prose, just because, and only because, what he wrote was not merely philosophy but literature. The form in which he wrote challenged attention and provoked admiration. That part of his work which some of us—which I myself, for instance—most care for is merely poetry. But in that part of his work which has exercised most attraction and has given him the widest reputation, the poetry, the form of expression, bears to the thought expressed much the same relation that the expression of Lucretius bears to the thought of Lucretius. As regards this, the great mass of his product, he is primarily a philosopher, whose writings surpass in value those of other similar philosophers precisely because they are not only philosophy but literature. In other words, Browning the philosopher is read by countless thousands to whom otherwise philosophy would be a sealed book, for exactly the same reason that Macaulay the historian is read by countless thousands to whom otherwise history would be a sealed book; because both Browning’s works and Macaulay’s works are material additions to the great sum of English literature. Philosophy is a science just as history is a science. There is need in one case as in the other for vivid and powerful presentation of scientific matter in literary form.

This does not mean that there is the like need in the two cases. History can never be truthfully presented if the presentation is purely emotional. It can never be truthfully or usefully presented unless profound research, patient, laborious, painstaking, has preceded the presentation. No amount of self-communion and of pondering on the soul of mankind, no gorgeousness of literary imagery, can take the place of cool, serious, widely extended study. The vision of the great historian must be both wide and lofty. But it must be sane, clear, and based on full knowledge of the facts and of their interrelations. Otherwise we get merely a splendid bit of serious romance-writing, like Carlyle’s “French Revolution.” Many hard-working students, alive to the deficiencies of this kind of romance-writing, have grown to distrust not only all historical writing that is romantic, but all historical writing that is vivid. They feel that complete truthfulness must never be sacrificed to color. In this they are right. They also feel that complete truthfulness is incompatible with color. In this they are wrong. The immense importance of full knowledge of a mass of dry facts and gray details has so impressed them as to make them feel that the dryness and the grayness are in themselves meritorious.

These students have rendered invaluable service to history. They are right in many of their contentions. They see how literature and science have specialized. They realize that scientific methods are as necessary to the proper study of history as to the proper study of astronomy or zoology. They know that in many, perhaps in most, of its forms, literary ability is divorced from the restrained devotion to the actual fact which is as essential to the historian as to the scientist. They know that nowadays science ostentatiously disclaims any connection with literature. They feel that if this is essential for science, it is no less essential for history.

There is much truth in all these contentions. Nevertheless, taking them all together, they do not indicate what these hard-working students believed that they indicate. Because history, science, and literature have all become specialized, the theory now is that science is definitely severed from literature and that history must follow suit. Not only do I refuse to accept this as true for history, but I do not even accept it as true for science.

Literature may be defined as that which has permanent interest because both of its substance and its form, aside from the mere technical value that inheres in a special treatise for specialists. For a great work of literature there is the same demand now that there always has been; and in any great work of literature the first element is great imaginative power. The imaginative power demanded for a great historian is different from that demanded for a great poet; but it is no less marked. Such imaginative power is in no sense incompatible with minute accuracy. On the contrary, very accurate, very real and vivid, presentation of the past can come only from one in whom the imaginative gift is strong. The industrious collector of dead facts bears to such a man precisely the relation that a photographer bears to Rembrandt. There are innumerable books, that is, innumerable volumes of printed matter between covers, which are excellent for their own purposes, but in which imagination would be as wholly out of place as in the blue prints of a sewer system or in the photographs taken to illustrate a work on comparative osteology. But the vitally necessary sewer system does not take the place of the cathedral of Rheims or of the Parthenon; no quantity of photographs will ever be equivalent to one Rembrandt; and the greatest mass of data, although indispensable to the work of a great historian, is in no shape or way a substitute for that work.

History, taught for a directly and immediately useful purpose to pupils and the teachers of pupils, is one of the necessary features of a sound education in democratic citizenship. A book containing such sound teaching, even if without any literary quality, may be as useful to the student and as creditable to the writer as a similar book on medicine. I am not slighting such a book when I say that, once it has achieved its worthy purpose, it can be permitted to lapse from human memory as a good book on medicine, which has outlived its usefulness, lapses from memory. But the historical work which does possess literary quality may be a permanent contribution to the sum of man’s wisdom, enjoyment, and inspiration. The writer of such a book must add wisdom to knowledge, and the gift of expression to the gift of imagination.

It is a shallow criticism to assert that imagination tends to inaccuracy. Only a distorted imagination tends to inaccuracy. Vast and fundamental truths can be discerned and interpreted only by one whose imagination is as lofty as the soul of a Hebrew prophet. When we say that the great historian must be a man of imagination, we use the word as we use it when we say that the great statesman must be a man of imagination. Moreover, together with imagination must go the power of expression. The great speeches of statesmen and the great writings of historians can live only if they possess the deathless quality that inheres in all great literature. The greatest literary historian must of necessity be a master of the science of history, a man who has at his finger-tips all the accumulated facts from the treasure-houses of the dead past. But he must also possess the power to marshal what is dead so that before our eyes it lives again.
