 There are two problems that we can distinguish here. The first is whether a non-normative account of malfunction is possible, about which much debate has taken place. A second problem has come into focus more recently. If there is a positive scientific account of function and malfunction that is pertinent to disease, which science owns it? The debate deriving from Boorse’s work has assumed that physiologists and pathologists have the last word here. Following Boorse, Hausman (2015, p. 9) is explicit that physiologists and pathologists are the relevant medical specialists whose judgments we care about. Lemoine and Giroux (2016) question the great stress on physiology to the exclusion of other medical specialties in Boorse – they think he has backed the wrong doctors. Lemoine and Giroux think we should see physiology as the science of how organisms work considered as assemblies of organ systems. But they think that the science of health and disease is defined by broader medical considerations that go beyond the physiological. Tied up with this is a broad consensus that the correct explanation of disease states is mechanistic, though this too has been challenged in the name of more abstract explanations from different parts of medicine (Darrason 2018).
