This issue of The Journal of Medicine and Philosophy assesses the deep and abiding tensions that exist among the competing epistemic perspectives that bear on medicine and morality. Concepts of health and disease, as well as the theoretical framing of medical ethics and health care policy, intersect with an overlapping set of culturally situated communities, striving to understand and manipulate the world in ways that each finds explanatory, appropriate, or otherwise befitting.
