Early-career philosophers of science often find themselves caught between a rock and a hard place, facing conflicting demands. While they have to meet the rigorous standards of a career in philosophy, they are at the same time expected to possess detailed knowledge of the sciences they study. By pulling in different directions, these two poles can be difficult to bridge. Interdisciplinarily engaged philosophers of science face not just an increased workload but also institutional conditions that are not always supportive for their engagement. For instance, while the need for interdisciplinary research is impressed upon young researchers by their advisers and by the subject matters of their research, universities and funding institutions, by contrast, still follow rather conservative and disciplinary policies when they fill positions or allocate funding. In March 2013, the interdisciplinarity of philosophy of science and the resulting situation for early career researchers was the subject of a workshop and a panel discussion funded by the Andrea von Braun Foundation. This paper takes up several of the issues that were controversially disputed at that event.

Philip Kitcher is one of the most distinguished philosophers of our days. Since the rise of philosophy of biology in the 1960s Kitcher has deeply influenced and inspired many of the debates in this field. Among his most important books are The Advancement of Science (1993), In Mendel’s Mirror: Philosophical Reflections on Biology (2003), and Science in a Democratic Society (2011). However, Kitcher’s philosophical interest is not restricted to the philosophy of science. Rather, he has also made groundbreaking contributions to ethics, to the philosophy of religion, to the philosophy of literature, to the philoso-phy of mathematics, and, most recently, to pragmatism. From a general perspective, two features of Kitcher’s work are particu-larly noteworthy. First, in most of his writings it becomes apparent that he takes a naturalistic stance. Kitcher characterizes himself as having an “impulse to naturalism”, which means that he resists the expansionist tendency to invoke entities or processes that are quite different from those studied in the various branches of inquiry (like Platonic forms or other abstract entities, Cartesian egos, and faculties of pure reason). Kitcher has explicated his naturalistic stance in The Naturalists Return (1992) and refined it in various recent works. Second, the philosophical questions that always have urged Kitcher most are questions that matter to human lives. Just to mention a few examples, these are questions like “How do we reconcile our scientific picture of the world with religion?”, “In which way does social practice impact scientist’s search for knowledge?”, or “How do we understand and improve our moral practices?”. In recent years Kitcher has argued that his focus is not merely due to his personal interests. Rather, he thinks that the only philosophical problems that are significant are those whose solution makes a difference to contemporary human life. Philosophers would be wise to focus on these pragmatically relevant kinds of questions, rather than addressing questions that are isolated from real life. In defending this claim, Kitcher expresses his affinity to the pragmatist tradition of Dewey and others. Thus, the second major characteristic of Kitcher’s work is that he takes up a pragmatist stance. Although Kitcher’s naturalistic and pragmatist impulses are discernible in most of his writings, he has only lately started to explicitly defend what he now calls pragmatic naturalism. His work on pragmatic naturalism contains innovative insights into questions about naturalism and pragmatism, while at the same time providing a meta-philosophical, unificatory framework for his longstanding work in various philosophical fields. Kitcher’s paper that is printed in this volume is one of the first publications in which he sets out his idea of pragmatic naturalism. This volume is the result of the 15th Münster Lectures in Philosophy which were hosted by the Department of Philosophy of the University of Münster from the 27th to the 29th of October 2011. The basic idea of the Lectures is to give advanced students of the Department the opportunity to get into discus-sion with important philosophers of our days. In line with what has become by now a venerable tradition, Kitcher gave a lecture to a public audience on the first evening of the Lectures, and he participated in a colloquium on the following two days. At this colloquium, eight groups of advanced students and faculty members presented papers on a wide range of topics from Kitch-er’s work. Both the lecture and the papers are published in this volume. In addition, it contains Kitcher’s detailed replies to the colloquium papers.

Back cover: This book develops a philosophical account that reveals the major characteristics that make an explanation in the life sciences reductive and distinguish them from non-reductive explanations. Understanding what reductive explanations are enables one to assess the conditions under which reductive explanations are adequate and thus enhances debates about explanatory reductionism. The account of reductive explanation presented in this book has three major characteristics. First, it emerges from a critical reconstruction of the explanatory practice of the life sciences itself. Second, the account is monistic since it specifies one set of criteria that apply to explanations in the life sciences in general. Finally, the account is ontic in that it traces the reductivity of an explanation back to certain relations that exist between objects in the world (such as part-whole relations and level relations), rather than to the logical relations between sentences. Beginning with a disclosure of the meta-philosophical assumptions that underlie the author’s analysis of reductive explanation, the book leads into the debate about reduction(ism) in the philosophy of biology and continues with a discussion on the two perspectives on explanatory reduction that have been proposed in the philosophy of biology so far. The author scrutinizes how the issue of reduction becomes entangled with explanation and analyzes two concepts, the concept of a biological part and the concept of a level of organization. The results of these five chapters constitute the ground on which the author bases her final chapter, developing her ontic account of reductive explanation.

This paper examines a specific kind of part-whole relations that exist in the molecular genetic domain. The central question is under which conditions a particular molecule, such as a DNA sequence, is a biological part of the human genome. I address this question by analyzing how biologists in fact partition the human genome into parts. This paper thus presents a case study in the metaphysics of biological practice. I develop a metaphysical account of genomic parthood by analyzing the investigative and reasoning practices in the ENCODE (ENCyclopedia Of DNA Elements) project. My account reveals two conditions that determine whether a molecule is a part of the human genome (i.e., a genomic part). First, genomic parts must possess a causal role function in the genome as a whole, that is, their functions must contribute to the genome directing the overall functioning of the cell. Second, genomic parts must have a specific chemical structure and be actual segments of the DNA sequence of the genome.

What is the level of organization on which natural selection operates? Are genes, organisms or groups the entities that are selected in adaptive evolutionary processes? This book discusses recent pluralistic solutions to the problem of the units of selection. After introducing central concepts and ideas from evolutionary biology, this book constructs a novel map of the philosophical debate and locates gene selectionism, multilevel selection theory, and description pluralism on the map. The book closes with a critical discussion of different versions of description pluralism and assesses their ability to solve the units of selection problem.

The term ‘environment’ is not uniformly defined in the public health sciences, which causes crucial inconsistencies in research, health policy, and practice. As we shall indicate, this is somewhat entangled with diverging pathogenic and salutogenic perspectives (research and policy priorities) concerning environmental health. We emphasise two distinct concepts of environment in use by the World Health Organisation. One significant way these concepts differ concerns whether the social environment is included. Divergence on this matter has profound consequences for the understanding of health and disease, for measures derived from that understanding targeting health promotion and disease prevention, and consequently, for epistemic structures and concept development in scientific practice. We hope to improve the given situation in public health by uncovering these differences and by developing a fruitful way of thinking about environment. Firstly, we side with the salutogenic conception of environment as a _health resource_ (as well as a source of health risks). Secondly, we subdivide the concept of environment into four _health-oriented environmental categories_ (viz., natural, built-material, socio-cultural, and psychosocial) and we link these with other theoretical notions proposed in the health sciences literature. Thirdly, we propose that in public health ‘environment’ should be understood as consisting of all extrinsic factors that influence or are influenced by the health, well-being, and development of an individual. Consequently, none of the four categories should be excluded from the concept of environment. We point out the practical relevance and fruitfulness of the conception of environment as a health source and frame this in causal terms, representing _individual health environments_ as causal networks. Throughout, we side with the view that for the design of human health-promoting settings, increased attention and consideration of environmental resources of salutogenic potential is particularly pressing.
