I think when it comes to “The paradox of literature” the author is trying to convey that this is when a piece of art or literature is contradicting its own style or changing things up to execute an entirely different meaning .

The poem “Parsley” By Rita Dove conveys this message when it shows the paradox in the line “mi madle, mi amol en muelte” because this showcases a different style of writing from the past lines before.
