Cooperation and conversation in the public sphere may overcome historical and other barriers to rational argumentation. As an alternative to evidence-based medicine (EBM) and patient-centered care (PCC), the recent development of a modern version of person-centered medicine (PCM) signals an opportunity for a conversational pluralogue to replace parallel monologues between EBM and its critics, and the calls to EBM to debate its critics. This article draws upon elements of Habermas’s theory of communicative action in order to suggest the kind of (...) pluralogue that is required for stakeholders in modern medicine to benefit more from publicly conversing with each other than speaking alone or using debate to argue against each other. This reasoned perspective has lessons for all discourse when deep value-based and epistemological differences cannot be easily adjudicated. (shrink)
