So physiology, as well as language, incomplete though the application of their tests to this matter has hitherto been, may lead us to hesitate before accepting the round assertion that it is vain to search for Celtic elements in any modern Englishman. But it is not only by the tests of physiology and language that we can try this matter. As there are for physiology physical marks, such as the square heads of the German, the round head of the Gael, the oval head of the Cymri, which determine the type of a people, so for criticism there are spiritual marks which determine the type, and make us speak of the Greek genius, the Teutonic genius, the Celtic genius, and so on. Here is another test at our service; and this test, too, has never yet been thoroughly employed. Foreign critics have indeed occasionally hazarded the idea that in English poetry there is a Celtic element traceable; and Mr. Morley, in his very readable as well as very useful book on the English writers before Chaucer, has a sentence which struck my attention when I read it, because it expresses an opinion which I, too, have long held. Mr. Morley says:—‘The main current of English literature cannot be disconnected from the lively Celtic wit in which it has one of its sources. The Celts do not form an utterly distinct part of our mixed population. But for early, frequent, and various contact with the race that in its half-barbarous days invented Ossian’s dialogues with St. Patrick, and that quickened afterwards the Northmen’s blood in France, Germanic England would not have produced a Shakspeare.’ But there Mr. Morley leaves the matter. He indicates this Celtic element and influence, but he does not show us,—it did not come within the scope of his work to show us,—how this influence has declared itself. Unlike the physiological test, or the linguistic test, this literary, spiritual test is one which I may perhaps be allowed to try my hand at applying. I say that there is a Celtic element in the English nature, as well as a Germanic element, and that this element manifests itself in our spirit and literature. But before I try to point out how it manifests itself, it may be as well to get a clear notion of what we mean by a Celtic element, a Germanic element; what characters, that is, determine for us the Celtic genius, the Germanic genius, as we commonly conceive the two.
