"

Beginning in the late 1970s, formalism was substantially displaced by various approaches (often with political aims or assumptions) that were suspicious of the idea that a literary work could be separated from its origins or uses.[citation needed] The term has often had a pejorative cast and has been used by opponents to indicate either aridity or ideological deviance.[citation needed] Some recent trends in academic literary criticism suggest that formalism may be making a comeback.[1]
