Autism has recently become the focus of continuous philosophical inquiry, because it affects inter-subjective capacities in a highly selective manner. One of the first behavioural manifestations of autism is impaired play, particularly the lack of pretend play. This article will show that the prevailing 'Theory-Theory of Mind'-approach cannot explain impaired play. I will suggest a richer, phenomenological account of inter-subjectivity. It will be argued that this improves the understanding of impaired play in autism.
