Didacticism of the Moderns (Pound, Eliot). Contemporary poets inherited from them the notion that experiment & technique are something separable and to be acquired. I think earlier poets considered these things something you learn in your apprenticeship & don't talk about too much.

Why? Because in the older sense of style, the aim was a holistic impression - a seamless unity of voice, manner, technique, subject. The complex becomes simple and the simple is complex; the poem resolves itself into a singleness, a unified impression, a whole.

Why I'm attracted to poets like Stevens & Crane, who are sceptical about the idea that technique + novelty = originality.
