The article develops the notion of the ‘hyperabject’ – coined by Danish poet Theis Ørntoft – into a proper theoretical concept. The term hyperabject is a synthesis of Timothy Morton's concept of hyperobjects and Julia Kristeva's theory of abjection, and in the article we argue that the concept of the hyperabject entails a necessary critique of and correction to Morton's ecological thought, as well as various other versions of speculative realism, new materialism and object-oriented ontology.
