It seems to be admitted, even by many of the poet's most devoted students, that his verse is, in its general character, harsh and rugged. To judge it fairly, one must free his mind of many merely conventional canons in regard to verse.
Pure music is absolute.
The music of verse moves, or should move, under the conditions of the thought which articulates it. It should serve as a chorus to the thought, expressing a mystic sympathy with it. Unrippled verse, which many readers demand, MUST be more or less mechanical. Such verse flows according to its own sweet will, independently of the thought-articulation. But the thought-articulation may be so flimsy that it's well enough for the verse so to flow.
