In this paper I draw on the French philosopher Michel Foucault for a viewpoint on aspects of EBM. This means that I develop his idea of the spaces occupied by disease. I give much of the paper to only one of these spaces, the space of perception of disease, in order to major on the medical gaze, one of Foucault’s best-known contributions to the philosophy of medicine. As I explain what I mean by each of the spaces of disease, I configure EBM into this space. The conscientious, explicit, and judicious use of current best evidence in making decisions about the care of individual patients. Evidence-based clinical practice requires integration of individual clinical expertise and patient preferences with the best available external clinical evidence from systematic research and consideration of available resources. EBM can be considered a subcategory of evidence-based healthcare, which also includes other branches of health-care practice such as evidence-based nursing or evidence-based physiotherapy. EBM subcategories include evidence-based surgery and evidence-based cardiology (Guyatt et al. 2008 , 783).
