Background: Edmund Pellegrino lamented that the cultural climate of the industrialized West had called the fundamental means and ends of medicine into question, leading him to propose a renewed reflection on medicine's basic concepts, including health, disease, and illness. My aim in this paper is take up Pellegrino's call. I argue that in order to usher in this renewal, the concept of ambiguity should take on a guiding role in medical practice, both scientific and clinical. After laying out Pellegrino's vision, I focus on the concept of normality, arguing that it undergirds modern medicine's other basic concepts. I draw on critiques by scholars in disability studies that show the concept of normality to be instructively ambiguous. Discussing the cases of Deafness and body integrity identity disorder (BIID), I argue that if medicine is to uphold its epistemic authority and fulfill its melioristic goals, ambiguity should become a central medical concept.
Methods: In this theoretical paper, I consider how central concepts in the philosophy of medicine are challenged by research on experiences of disability. In particular, the idea that medical knowledge produces universal truths is challenged and the importance of historical, cultural, and otherwise situated knowledge is highlighed.
Results: I demonstrate how experiences of disability complicate dominant theories in the philosophy of medicine and why medical practice and the philosophy of medicine should make ambiguity a central concept.
Conclusions: If medical practitioners and philosophers of medicine wish to improve their understanding of the meaning and practice of medicine, they should take seriously the importance and centrality of ambiguity.
