A type of "Poetic Justice" - one that's almost forgotten.
Poetic form and content could not be separated, since the experience of reading the particular words of a poem, including its unresolved tensions, is the poem’s “meaning.” As a result, any rewording of a poem’s language alters its content, a view articulated in the phrase “the heresy of paraphrase,” which was coined by Brooks in his The Well Wrought Urn(1947).
And the "Occam's Razor" (parenthesis or "quotation marks") that should be applied to sources of discussion.
Formalism is a school of literary criticism and literary theory having mainly to do with structural purposes of a particular text. It is the study of a text without taking into account any outside influence. Formalism rejects (or sometimes simply "brackets", i.e., ignores for the purpose of analysis) notions of culture or societal influence, authorship, and content, and instead focuses on modes, genres, discourse, and forms.
