Medicine raises numerous philosophical issues. Most discussed have been debates in bioethics. Yet contemporary medicine is also a rich source of controversies and examples that raise important issues in philosophy of science, philosophy of biology, and metaphysics. This volume approaches the philosophy of medicine from the broad naturalist perspective that holds that philosophy must be continuous with, constrained by, and relevant to empirical results of the natural and social sciences and that believes that the history, sociology, politics, and ethics of science provide relevant information for philosophical analysis. One traditional topic covered by several of the contributions is the nature of disease, but the approach is largely from the philosophy of science rather than traditional linguistic analysis. The complex interplay of epistemological and sociological factors in producing evidence in medicine is discussed by chapters on collective medical discussion making, experimental medicine," genetic" diseases, mental illness, and race and gender categories. The upshot is a volume that ties medicine to contemporary issues in philosophy of science and metaphysics like no other.

a ~a ]An excellent collection of essays in the philosophy of medicine. Whereas most philosophical work about medicine has been concerned with medical ethics, this volume focuses more on key questions in epistemology and metaphysics, although many of these are also relevant to ethical issues. Some of the chapters are among the best I have read in the philosophy of medicine on their respective topics.a (TM)

Jennifer McKitrick offers an opinionated guide to the philosophy of dispositions. In her view, when an object has a disposition, it is such that, if a certain type of circumstance were to occur, a certain kind of event would occur. Since it is very common for this to be the case for a variety of reasons, dispositions are very abundant and diverse. They include such varied properties as character traits like a hero's courage, characteristics of physical objects like a wine glass's fragility, and characteristics of microphysical entities like an electron's charge. Some dispositions are natural while others are non-natural. Some dispositions called "powers" are ungrounded while non-fundamental dispositions are grounded in other properties. Some dispositions manifest constantly, some of them manifest spontaneously, while others manifest only when they are triggered to do so. Some dispositions manifest by causing another dispositional property to be instantiated, while others have manifestations that involve non-dispositional properties and relations. Some dispositions are intrinsic to their bearers while others are extrinsic. Some of them are causally relevant to their manifestations while others are not. Some dispositions manifest in some particular way in particular circumstances, while other dispositions manifest in various ways in various circumstances. What makes all of these diverse properties dispositions is their connection to a certain kind of counterfactual fact. Nevertheless, disposition ascriptions are not semantically reducible to counterfactual claims.
