Chapter 3 intervenes in debates about whether the historic avant-garde (Dada, Futurism, Surrealism) represented a general tendency within modernism or a critical alternative to ideas of artisanal autonomy. The impact of World War I on medical, prosthetic, and psychoanalytic technologies was instrumental among postwar artists in imagining a damaged, wounded, or psychotic body. If the body could be seen as fragmented, recombined, and disjointed, as it was in Surrealism, it could also be imagined as promising a different ontology, one in which fragmentation or madness could be enlisted in revolutionary projects. Through readings of F. T. Marinetti’s novel, Mafarka the Futurist, Tristan Tzara’s The Gas Heart, and the self-portraiture of Frida Kahlo, the chapter explores works in which bodies are removed from narratives of reproductive futurity, organic coherence, and normalcy and seen through the optic of disability.
