If one had to identify the biggest change within the philosophical tradition in the 21st century, it would certainly be the rapid rise of experimental philosophy to address differences in intuitions about concepts. Yet, it is within the philosophy of medicine that one particular conceptual debate has overshadowed all others: the long-standing dispute between so-called 'naturalists' and 'normativists' about the concepts of health and disease. It is, therefore, surprising that the philosophy of medicine has, so far, not drawn on the tools of XPhi. I shall use this opportunity to defend and advocate the use of empirical methods to inform and advance this and other debates within the philosophy of medicine.
