Abstract
This paper explores the enduring impact of Cartesian dualism on the formulation of autism diagnosis and its subsequent implications for our contemporary understanding of the condition. It presents a concise historical overview tracing the evolution of autism diagnosis through the lenses of two traditional reductionist paradigms: a psychological framework (emphasizing it as a mental disorder) and a biological framework (viewing it as a neurological dysfunction). However, the paper argues for a revised perspective that transcends the limitations inherent in both conventional viewpoints and challenges the Cartesian dichotomy between the physical and the mental realms. Instead, it proposes an instrumentalist conception of mental phenomena. This conceptual shift is motivated by the ethical imperative of affording autistic individuals a more dignified and inclusive standing within society, one that acknowledges their moral value.
