twentieth-century literature about the distinction between explanation and und- standing)? Second, can we do justice to a particular writer's notion of that category by taking at face value what he writes about his own motivation for adopting it? In response to both types of questions, there is by now a consensus amongst many historians of science and of philosophy that (a) intellectual history - like other kinds of history - has to be careful not to uncritically adopt actors' categories, and (b) more generally, even the actors' own thinking about a particular issue has to be contextualized vis-a-vis their other intellectual commitments and interests, as well as the complex conditions that make the totality of their commitments possible. Such conditions include cognitive as well as practical, institutional, and cultural factors. The articles in this volume respond to these challenges in several ways. For example, one author (Christopher Pincock) seeks to read some of the nineteen- century philosophical writings about Erklaren and Verstehen as standing for a more fundamental problem, which he terms the problem of the "unity of experience.""

This volume is a collection of original essays focusing on a wide range of topics in the History and Philosophy of Science. It is a festschrift for Peter Machamer, which includes contributions from scholars who, at one time or another, were his students. The essays bring together analyses of issues and debates spanning from early modern science and philosophy through the 21st century. Machamer's influence is reflected in the volume's broad range of topics. These include: underdetermination, scientific practice, scientific models, mechanistic explanation in contemporary and historical science, values in science, the relationship between philosophy and psychology, experimentation, supervenience and reductionism.

Recent philosophy and history of science has seen a surge of interest in the role of concepts in scientific research. Scholars working in this new field focus on scientific concepts, rather than theories, as units of analysis and on the ways in which concepts are formed and used rather than on what they represent. They analyze what has traditionally been called the context of discovery, rather than (or in addition to) the context of justification. And they examine the dynamics of research rather than the status of the finished research results. This volume provides detailed case studies and general analyses to address questions raised by these points, such as: - Can concepts be clearly distinguished from the sets of beliefs we have about their referents? - What - if any - sense can be made of the separation between concepts and theories? - Can we distinguish between empirical and theoretical concepts? - Are there interesting similarities and differences between the role of concepts in the empirical sciences and in mathematics? - What underlying notion of investigative practice could be drawn on to explicate the role of concept in such practice? - From a philosophical point of view, is the distinction between discovery and justification a helpful frame of reference for inquiring into the dynamics of research? - From a historiographical point of view, does a focus on concepts face the danger of falling back into an old-fashioned history of ideas?
