But the forms of its language are not our only key to a people; what it says in its language, its literature, is the great key, and we must get back to literature. The literature of the Celtic peoples has not yet had its Zeuss, and greatly it wants him. We need a Zeuss to apply to Celtic literature, to all its vexed questions of dates, authenticity, and significance, the criticism, the sane method, the disinterested endeavour to get at the real facts, which Zeuss has shown in dealing with Celtic language. Science is good in itself, and therefore Celtic literature,—the Celt-haters having failed to prove it a bubble,—Celtic literature is interesting, merely as an object of knowledge. But it reinforces and redoubles our interest in Celtic literature if we find that here, too, science exercises the reconciling, the uniting influence of which I have said so much; if we find here, more than anywhere else, traces of kinship, and the most essential sort of kinship, spiritual kinship, between us and the Celt, of which we had never dreamed. I settle nothing, and can settle nothing; I have not the special knowledge needed for that. I have no pretension to do more than to try and awaken interest; to seize on hints, to point out indications, which, to any one with a feeling for literature, suggest themselves; to stimulate other inquirers. I must surely be without the bias which has so often rendered Welsh and Irish students extravagant; why, my very name expresses that peculiar Semitico-Saxon mixture which makes the typical Englishman; I can have no ends to serve in finding in Celtic literature more than is there. What _is_ there, is for me the only question. III.
