What is the theme in Paradoxes and Oxymorons by John Ashbery?

Language and meaning are themes to this book. "Paradoxes and Oxymorons" questions the idea that language is an effective tool for communicating ideas about the physical, empirically verifiable world. The poem suggests that poetry, and by extension all language, is ultimately about itself and its inability to say anything definitive about the world. The first stanza underscores this idea, as the poem eludes the understanding of the reader: "You miss it, it misses you. You miss each other." These words also echo the way that lovers frequently misunderstand one another, showing how language is often at a distance from things.
