The difference is not a simple difference of degree between poets. It is something which had happened to the mind of England between the time of Donne or Lord Herbert of Cherbury and the time of Tennyson and Browning; it is the difference between the intellectual poet and the reflective poet, Tennyson and Browning are poets, and they think; but they do not feel their thought as immediately as the odour of a rose. A thought to Donne was an experience; it modified his sensibility. When a poet's mind is perfectly equipped for its work, it is constantly amalgamating disparate experience; the ordinary man's experience is chaotic, irregular, fragmentary. The latter falls in love, or reads Spinoza, and these two experiences have nothing to do with each other, or with the noise of the typewriter or the smell of cooking; in the mind of the poet these experiences are always forming new wholes. We may express the difference by the following theory:--The poets of the seventeenth century, the successors of the dramatists of the sixteenth, possessed a mechanism of sensibility which could devour any kind of experience. They are simple, artificial, difficult, or fantastic, as their predecessors were; no less nor more than Dante, Guido Cavalcanti, Guinizelli, or Cino. In the seventeenth century a dissociation of sensibility set in, from which we have never recovered; and this dissociation, as is natural, was due to the influence of the two most powerful poets of the century, Milton and Dryden. Each of these men performed certain poetic functions so magnificently well that the magnitude of the effect concealed the absence of others. The language went on and in some respects improved; the best verse of Collins, Gray, Johnson, and even Goldsmith satisfies some of our fastidious demands better than that of Donne or Marvell or King. But while the language became more refined, the feeling became more crude. The feeling, the sensibility, expressed in the "Country Churchyard" (to say nothing of Tennyson and Browning) is cruder than that in the "Coy Mistress." The second effect of the influence of Milton and Dryden followed from the first, and was therefore slow in manifestation. The sentimental age began early in the eighteenth century, and continued. The poets revolted against the ratiocinative, the descriptive; they thought and felt by fits, unbalanced; they reflected. In one or two passages of Shelley's "Triumph of Life," in the second "Hyperion," there are traces of a struggle toward unification of sensibility. But Keats and Shelley died, and Tennyson and Browning ruminated.
