Taking its starting point from Mark Haddon’s The Curious Incident of the Dog in the Night-Time, a novel featuring an autistic first-person narrator, this paper explores the capabilities and limits of narrative as a cognitive instrument with special attention to the connection between knowing, living, and telling. In the novel the impairments connected with autism, affecting social interaction and the understanding of other persons as beings with minds of their own, influence both the narrator’s style of telling his story and his way of using narrative thinking to plan the future and conceive of the past. The discussion focuses on both these issues, arguing that narrative is not only a cultural technique which enables orientation in time and space as well as the understanding of other agents as intentional – that it is a highly social art, of vital importance for everyday action and interaction in a web of social relations.
