To assert that medicine would not exist without patients is an understatement, and we can agree that, in medical research and philosophical debates, the patient is assessed as the measure of all things. However, without medical professionals, patients could not live. Therefore, this interplay underscores the need to explore the patients’ and doctors’ distinct and shared features as “the measure of all things.” The chapter is divided into four main sections that pursue this endeavour using Kit Fine’s relationism approach in the doctor-patient bionomy. The first two sections analyse patients’ and doctors’ intrinsic and extrinsic characteristics taken individually and in conjunction. The third section introduces a Breuer-Sigmund thought experiment, exploring the dynamic in two scenarios: when the patient’s intrinsic values align with the doctor’s and when they differ significantly. Consequently, section four argues that the biomedical model (BMM) is not inherently non-humanistic, just as the biopsychosocial model (BPSM) is not always humanistic; it, thus, emphasises the need for a nuanced approach considering the doctor as much as the patient’s belief systems, expectations and needs.
