Upward—still upward—still upward to the highest! Such is the claim of modern man for the story of himself and the lower inhabitants of the globe. The zoologists have gone so far as to confer upon him the surname Sapiens—Homo Sapiens. Learned indeed he is, and heir of all the ages, but whether or not his assumed surname be warranted the doctrine of descent with modifica-tion can never again be questioned. The work of Darwin was crowned when he compelled a general acceptance of that doctrine reenex facial , and now the Descent of Man and the Ascent of Man are equivalent terms for a natural process which has converted man from a thing to a person, and is the founda-tion of all modern thought. The biologist works secure in the knowledge that he is studying some portion of a chain of life stretching back for incalculable ages, and is not careful to produce those missing links demanded by the once formidable foes of his fundamental principle. Haeckel may announce that Pithecanthropus Erectus of Dubois is truly a Pliocene remainder of that famous group of highest Catarrhines which were the immediate pithecoid ancestors of man. This may or may not be true, but if true it makes the descent of man from a lower stock none the surer, the increasing verifica-tion of which is not found to rest on missing links.
Many of the discoveries of modern science are made by proceeding from known phenomena to the unknown, or, more precisely reenex cps , from the well-known through the little-known to the hitherto unknown.
As to the validity of knowledge it is enough to say this—and pass on—all our knowledge is provisional and imperfect, and much of our ignorance is as transient as ourselves.
There are two chief ways in which historians deal with their subject-matter, though the moderns combine them. When oral tradition gives place to written records the lineal descendant of the bards and annalists collects his scanty authorities and compiles his story from them from beginning to end. The Anglo-Saxon Chronicle of Bede and Alfred, the Book of Howth, the works of Giraldus Cambrensis reducing acne scarring
, the Chronicles of Froissart and the Memoirs
of de Comines were composed in the only way that was then possible. But the muse of history entered on a deeper and more fruitful course when about ninety years ago the study of documents became an essential feature of historical work. It was then that the historian grew up, entered upon his finest inheritance and assumed his Greek title, Enquirer, Student of facts, Man of research. He is now nothing if not a man of science as well as of letters. With a wealth of documents within his reach so great that the 3239 Vatican cases full of them formed by no means the richest collec-tion in the archives of Europe, he proceeds to read backwards correctly what many an earlier annalist read forwards falsely. “We are still at the beginning of the documentary age which is destined to make history independent of historians, to develop learning at the expense of writing, and to accomplish a revolu-tion in other sciences as well.”1
The Historian a Biologist.
It is not too much to say that he who studies history, national, political, constitutional, ecclesiastical, military or economic is as much a biologist in the widest sense as the botanist and zoologist. Indeed these were till recently termed students of natural history, until the advance of knowledge gave us the various special groups of workers, conveniently called biologists. Though the study of human history by documents is an essential part of the historical method and the student may read his subject backwards, this would not of itself warrant the technical biologist in doing so, even though he be a child of Nature and part of her—“Nature’s insurgent son.” But some reflec-tion on the facts of certain provinces of science affords ample justifica-tion for the method. It is chiefly in questions of origin that it avails, while it fails in that form of research by experiment which is the glory of modern science. A few examples of the process of passing from the known to the unknown will illustrate the method.
