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.

Medicine has been a very fruitful source of significant issues for philosophy over the last 30 years. The vast majority of the issues discussed have been normative – they have been problems in morality and political philosophy that now make up the field called bioethics. However, biomedical science presents many other philosophical questions that have gotten relatively little attention, particularly topics in metaphysics, epistemology and philosophy of science. This volume focuses on problems in these areas as they surface in biomedical science. Important changes in philosophy make biomedical science an especially int- esting area of inquiry. Contemporary philosophy is largely naturalistic in approach – it takes philosophy to be constrained by the results of the natural sciences and able to contribute to the natural sciences as well. Exactly what those constraints and contributions should be is a matter of controversy. What is not controversial is that important questions in philosophy of science and metaphysics are raised by the practice of science. Physics, biology, and economics have all drawn extensive phi- sophical analysis, so much so that philosophical study of these areas have become specialized subdisciplines within philosophy of science. Philosophy of medicine approached from the perspective of philosophy of science – with important exc- tions (Schaffner, 1993; Thagard, 2000) – has been relatively undeveloped. Nonetheless, medicine should have a central place in epistemological and metaphysical debates over science.
