Heresy of Paraphrase

I think the New Critical "heresy of paraphrase" doctrine is an extension of symbolist poetics of ineffability. Now it is not just experience (of a certain type) that is ineffable (inexpressible in language) but that even the meaning of a poem cannot be expressed in language, other than the original language of the poem itself. Symbolist poetry emulates the ineffability of music, its indefineteness of reference.
