The following remarks on the study of Celtic Literature formed the substance of four lectures given by me in the chair of poetry at Oxford. They were first published in the Cornhill Magazine, and are now reprinted from thence. Again and again, in the course of them, I have marked the very humble scope intended; which is, not to treat any special branch of scientific Celtic studies (a task for which I am quite incompetent), but to point out the many directions in which the results of those studies offer matter of general interest, and to insist on the benefit we may all derive from knowing the Celt and things Celtic more thoroughly. It was impossible, however, to avoid touching on certain points of ethnology and philology, which can be securely handled only by those who have made these sciences the object of special study. Here the mere literary critic must owe his whole safety to his tact in choosing authorities to follow, and whatever he advances must be understood as advanced with a sense of the insecurity which, after all, attaches to such a mode of proceeding, and as put forward provisionally, by way of hypothesis rather than of confident assertion.
