But this definition today seems to me only a twisted phrase which, by means of two negatives, conceals an anacoluthon.
From the en.wikipedia.org
In its most restrictive meaning, anacoluthon requires that the introductory elements of a sentence lack a proper object or complement.
From the en.wikipedia.org
In prose, anacoluthon is often used in stream of consciousness writing, such as that of James Joyce, because it is characteristic of informal human thought.
From the en.wikipedia.org
For example, if the beginning of a sentence sets up a subject and verb, but then the sentence changes its structure so that no direct object is given, the result is anacoluthon.
From the en.wikipedia.org
As a figure, anacoluthon directs a reader's attention, especially in poetry, to the syntax itself and highlights the mechanics of the meaning rather than the object of the meaning.
