English to Japanese Art/Literary Poetry & Literature literary theory

Absurdism uses, in reduced form, the Romantic "two worlds".

What the author of the sentence meant to say is that in 18th century European Romantic literature there is duality of "human world" (or physical world accessible to empirical experience) and "sublime world of spirit(s)" (the realm of God(s) and/or platonic "pure ideas"). Absurdism as a way of reality representation in literature, manifested in works by Gogol, Kafka, Beckett, Ionesko and etc., reduces this duality to merging of "everyday reality"(realistic representations of our empirical reality) and demonic (low, as opposed to Romanticism's Sublime) supernatural elements. This is the explanation of the "reduced form", so nothing like 還元形／還元体／最簡形／正規形 would do. Any ideas? Pleeease!
