This chapter turns attention to the art of the psychotic, often collected under the umbrella of ‘Outsider art’, considering how the question of orality and literacy can shed further light on the widely noted stylistic affinities between outsider art, child art and tribal art. The chapter begins by looking to two major theorists of orality and literacy whose work both draws a surprising link between psychosis and orality: Walter Ong and Marshall McLuhan. McLuhan has suggested that ‘schizophrenia may be a necessary consequence of literacy’ (The Gutenberg Galaxy), whilst Ong has suggested a possible link between orality and ‘bicameralism’ (Orality and Literacy), which essentially amounts to a proposition of oral consciousness equating schizophrenic consciousness. Through a close analysis of some of the most influential theorists of schizophrenia, these theories are brought into dialogue with orality and literacy studies, demonstrating certain striking parallels between the psychodynamics of orality and the psychotic. The chapter also examines psychotic speech and use of language, similarly noting the clear connection to methods of speech in orality. It is described how this surprising correlation is illuminated by the work of Jacques Lacan, who suggests the psychotic is detached from the Symbolic order (often due to some extreme trauma), which correlates with the psychology of literacy. Once again, this detachment from literacy is concurrent with a clear set of stylistic traits in visual art.
