The poem “Tierras en erosión” [Eroding Lands] by twentieth-century Argentine poet Olga Orozco evokes aspects of autism such as sensory overload, chaos and fear, isolation from non-autistics, and awareness of alienation, as conveyed by first-hand accounts of people on the autism spectrum. Orozco and researchers and writers with autism such as Temple Grandin, William Stillman, Kamran Nazeer, and Donna Williams express an insider’s view of the realities of the experience of autism. In doing so, they overcome the limits of reductive representations of autism such as the theory of mind analysis which makes the erroneous assumption that people with autism are incapable of perceiving that other people have separate minds and modes of thought.
