Irrealism is a critical term used across philosophy, literature, and art for works that are not merely unreal but estranged from our accepted sense of reality - so that the impossible quietly undermines the everyday. In literature it was applied in the 1970s to the post-realist 'new fiction' of Donald Barthelme and John Barth, and later to the dream-logic fictions of Kafka, Borges, and Calvino. In painting, critics have read Giorgio de Chirico's shadowed, empty piazzas and Remedios Varo's private allegorical machines as irrealist, and the Australian art press has detected a 'New Irrealism' of ghostly, low-key canvases. Unlike fantasy or magic realism, irrealism offers no coherent secondary world: it stages a zone of irreality - 'that which is beyond the real' - that offsets and threatens the real, and as the artist Tristan Tondino insisted, it has no single fixed style.
