RESUMEN
This essay explores the connections between the modern autism intervention Applied Behavioral Analysis (ABA) and medieval personification allegory to show how literature powerfully enables the work of neurodiversity. Invoking the theory of the language game to investigate the clinical history of ABA, the essay puts the fourteenth-century poet William Langland in dialogue with Ludwig Wittgenstein and Stanley Cavell. I argue that the approach to language emerging from this constellation of voices works as a precise tool for diagnosing the ethical liabilities of ABA. By highlighting the shared interest in a set of animated terms across different historical and disciplinary domains, we can see how allegorical writing becomes an essential resource for exposing how ABA travesties human need and emotion. Working against the ethos of this "therapeutic" intervention, Langland, Wittgenstein, and Cavell join with autistic writers in advancing a model of language development based on mutuality, reciprocity, and shared forms of life.
