Wordsworth, as we have said, is the chief representative of some (especially one) of the most important principles in the Romantic Movement; but he is far more than a member of any movement; through his supreme poetic expression of some of the greatest spiritual ideals he belongs among the five or six greatest English poets. First, he is the profoundest interpreter of Nature in all poetry. His feeling for Nature has two aspects. He is keenly sensitive, and in a more delicately discriminating way than any of his predecessors, to all the external beauty and glory of Nature, especially inanimate Nature--of mountains, woods and fields, streams and flowers, in all their infinitely varied aspects. A wonderfully joyous and intimate sympathy with them is one of his controlling impulses. But his feeling goes beyond the mere physical and emotional delight of Chaucer and the Elizabethans; for him Nature is a direct manifestation of the Divine Power, which seems to him to be everywhere immanent in her; and communion with her, the communion into which he enters as he walks and meditates among the mountains and moors, is to him communion with God. He is literally in earnest even in his repeated assertion that from observation of Nature man may learn (doubtless by the proper attuning of his spirit) more of moral truth than from all the books and sages. To Wordsworth Nature is man's one great and sufficient teacher. It is for this reason that, unlike such poets as Keats and Tennyson, he so often views Nature in the large, giving us broad landscapes and sublime aspects. Of this mystical semi-pantheistic Nature-religion his 'Lines composed above Tintern Abbey' are the noblest expression in literature. All this explains why Wordsworth considered his function as a poet a sacred thing and how his intensely moral temperament found complete satisfaction in his art. It explains also, in part, the limitation of his poetic genius. Nature indeed did not continue to be to him, as he himself says that it was in his boyhood, absolutely 'all in all'; but he always remained largely absorbed in the contemplation and interpretation of it and never manifested, except in a few comparatively short and exceptional poems, real narrative or dramatic power (in works dealing with human characters or human life).
