I am alive to a usual objection to what is clearly part of my programme for the _métier_ of poetry. The objection is that the doctrine requires a ridiculous amount of erudition (pedantry), a claim which can be rejected by appeal to the lives of poets in any pantheon. It will even be affirmed that much learning deadens or perverts poetic sensibility. While, however, we persist in believing that a poet ought to know as much as will not encroach upon his necessary receptivity and necessary laziness, it is not desirable to confine knowledge to whatever can be put into a useful shape for examinations, drawing-rooms, or the still more pretentious modes of publicity. Some can absorb knowledge, the more tardy must sweat for it. Shakespeare acquired more essential history from Plutarch than most men could from the whole British Museum. What is to be insisted upon is that the poet must develop or procure the consciousness of the past and that he should continue to develop this consciousness throughout his career. What happens is a continual surrender of himself as he is at the moment to something which is more valuable. The progress of an artist is a continual self-sacrifice, a continual extinction of personality. There remains to define this process of depersonalization and its relation to the sense of tradition. It is in this depersonalization that art may be said to approach the condition of science. I shall, therefore, invite you to consider, as a suggestive analogy, the action which takes place when a bit of finely filiated platinum is introduced into a chamber containing oxygen and sulphur dioxide. II Honest criticism and sensitive appreciation is directed not upon the poet but upon the poetry. If we attend to the confused cries of the newspaper critics and the susurrus of popular repetition that follows, we shall hear the names of poets in great numbers; if we seek not Blue-book knowledge but the enjoyment of poetry, and ask for a poem, we shall seldom find it. In the last article I tried to point out the importance of the relation of the poem to other poems by other authors, and suggested the conception of poetry as a living whole of all the poetry that has ever been written. The other aspect of this Impersonal theory of poetry is the relation of the poem to its author. And I hinted, by an analogy, that the mind of the mature poet differs from that of the immature one not precisely in any valuation of “personality,” not being necessarily more interesting, or having “more to say,” but rather by being a more finely perfected medium in which special, or very varied, feelings are at liberty to enter into new combinations.
