This book investigates how collaborative scientific practice yields scientific knowledge. At a time when most of today’s scientific knowledge is created in research groups, the author reconsiders the social character of science to address the question of whether collaboratively created knowledge should be considered as collective achievement, and if so, in which sense. Combining philosophical analysis with qualitative empirical inquiry, this book provides a comparative case study of mono- and interdisciplinary research groups, offering insight into the day-to-day practice of scientists. (...) The book includes field observations and interviews with scientists to present an empirically-grounded perspective on much-debated questions concerning research groups’ division of labor, relations of epistemic dependence and trust.

This paper revisits the often debated question Can machines think? It is argued that the usual identification of machines with the notion of algorithm has been both counter-intuitive and counter-productive. This is based on the fact that the notion of algorithm just requires an algorithm to contain a finite but arbitrary number of rules. It is argued that intuitively people tend to think of an algorithm to have a rather limited number of rules. The paper will further propose a modification (...) of the above mentioned explication of the notion of machines by quantifying the length of an algorithm. Based on that it appears possible to reconcile the opposing views on the topic, which people have been arguing about for more than half a century. (shrink)

A central problem for the international governance of heritable germline gene editing is that there are important differences in attitudes and values as well as ethical and health care considerations around the world. These differences are reflected in a complicated and diverse regulatory landscape. Several publications have discussed whether reproductive uses would be legally permissible in individual countries and whether clinical applications could emerge in the context of regulatory gaps and gray areas. Systematic comparative studies that explore issues related to (...) the governance of this technology from different national and international perspectives are needed to address the lack of knowledge in this area. In this research report, we contribute to filling this gap by presenting views of stakeholders in the United Kingdom on challenges to the governance of heritable genome editing. We present findings from a multistakeholder study conducted in the United Kingdom between October 2016 and January 2018 and funded by the Wellcome Trust. This research included interviews, literature analysis, and a workshop. We involved leading U.K. scientists, in vitro fertilization clinicians, and representatives from regulatory bodies, patient organizations, and other civil societal organizations, as well as fertility companies. Part one of this article explores stakeholder perceptions of possible global developments in heritable genome editing and associated risks and governance challenges. Part two presents a range of policy options that were generated during the workshop in relation to the challenges discussed in part one. (shrink)

This paper offers an analytic perspective on epistemic dependence that is grounded in theoretical discussion and field observation at the same time. When in the course of knowledge creation epistemic labor is divided, collaborating scientists come to depend upon one another epistemically. Since instances of epistemic dependence are multifarious in scientific practice, I propose to distinguish between two different forms of epistemic dependence, opaque and translucent epistemic dependence. A scientist is opaquely dependent upon a colleague if she does not possess (...) the expertise necessary to independently carry out, and to profoundly assess, the piece of scientific labor which her colleague is contributing. If the scientist does possess the necessary expertise, I argue, her dependence is translucent. However, the distinction between opaque and translucent epistemic dependence does not exhaust dependence relations in scientific practice, because many dependence relations are neither entirely opaque nor translucent. I will discuss why this is the case, and show how we can make sense of the gray zone between opaque and translucent epistemic dependence. (shrink)

In interdisciplinary research scientists have to share and integrate knowledge between people and across disciplinary boundaries. An important issue for philosophy of science is to understand how scientists who work in these kinds of environments exchange knowledge and develop new concepts and theories across diverging fields. There is a substantial literature within social epistemology that discusses the social aspects of scientific knowledge, but so far few attempts have been made to apply these resources to the analysis of interdisciplinary science. Further, (...) much of the existing work either ignores the issue of differences in background knowledge, or it focuses explicitly on conflicting background knowledge. In this paper we provide an analysis of the interplay between epistemic dependence between individual experts with different areas of expertise. We analyze the cooperative activity they engage in when participating in interdisciplinary research in a group, and we compare our findings with those of other studies in interdisciplinary research.

Based on an empirical study of a research team in natural science, the author argues that collaborating scientists do not trust each other completely. Due to the inherent incompleteness of trust, epistemic trust among scientists is not sufficient to manage epistemic dependency in research teams. To mitigate the limitations of epistemic trust, scientists resort to specific strategies of indirect assessment such as dialoguing practices and the probing of explanatory responsiveness. Furthermore, they rely upon impersonal trust and deploy practices of hierarchical (...) authorship. (shrink)

Bioethical debates on the use of human embryos and oocytes for stem cell research have often been criticized for the lack of empirical insights into the perceptions and experiences of the women and couples who are asked to donate these tissues in the IVF clinic. Empirical studies that have investigated the attitudes of IVF patients and citizens on the donation of their embryos and oocytes have been scarce and have focused predominantly on the situation in Europe and Australia. This article (...) examines the viewpoints on the donation of embryos for stem cell research among IVF patients and students in China. Research into the perceptions of patients is based on in-depth interviews with IVF patients and IVF clinicians. Research into the attitudes of students is based on a quantitative survey study. The empirical findings in this paper indicate that perceptions of the donation of human embryos for stem cell research in China are far more diverse and complex than has commonly been suggested. Claims that ethical concerns regarding the donation and use of embryos and oocytes for stem cell research are typical for Western societies but absent in China cannot be upheld. The article shows that research into the situated perceptions and cultural specificities of human tissue donation can play a crucial role in the deconstruction of politicized bioethical argumentation and the assumptions about “others” that underlie socio-ethical debates on the moral dilemmas of technology developments in the life sciences.

This essay explores how indigenous knowledge about plant and animal remedies was gathered, classified, tested, and circulated across wide networks of exchange for natural knowledge between Europe and the Americas. There has been much recent interest in the “bioprospecting” of local natural resources—medical and otherwise—by Europeans in the early modern world and the strategies employed by European travellers, missionaries, or naturalists have been well documented. By contrast, less is known about the role played by indigenous and Creole intermediaries in this (...) process. And yet, the transmission of knowledge between indigenous communities and the European cabinet was neither transparent nor natural, and often involved epistemological, linguistic, and religious obstacles. Drawing on printed and manuscript collections of indigenous remedies, written in colonial Mexico between the sixteenth and the eighteenth centuries, I focus on how local intermediaries, like creoles scholars, sought to overcome such obstacles by observing indigenous uses of remedies, by studying indigenous languages and by producing natural histories and pharmacopoeias in indigenous languages. Ultimately, behind the Creole participation in the transmission of indigenous remedies, one can point to political and cultural interests and to inclusive definitions of knowledge, which cut across oppositions between science and superstition, cabinet and field, centre and periphery.

Zusammenfassung Eine Karriere im Hochleistungssport ist mit hohen zeitlichen Belastungen verbunden. Da die Spitzensport- Karriere lebenszeitlich beschränkt ist und in der Regel in der vierten Lebensdekade beendet wird, stellt sich die Frage nach den Auswirkungen eines Engagements im Hochleistungssport auf die Berufskarriere. Hierzu wurden im Rahmen einer quantitativ orientierten Kohortenanalyse ehemalige Spitzensportler zu ihrem beruflichen Werdegang und möglichen Einflussfaktoren des Hochleistungssports retrospektiv befragt. Die Befunde der beiden Teiluntersuchungen zeigen, dass die hohen zeitlichen Anforderungen des Spitzensports den beruflichen Werdegang nur zum (...) Teil beeinträchtigen. Dies gilt nicht nur für sehr erfolgreiche Sportler, sondern auch für Hochleistungssportler, die weniger erfolgreich sind, sowie für Profisportler, die besonders intensiv in das System Hochleistungssport eingebunden sind. Dabei wirken sich Faktoren, wie institutionelle Unterstützungsmaßnahmen, Bekanntheit und soziale Kontakte sowie die Chance im Berufsfeld Spitzensport zu arbeiten, positiv auf die Berufskarriere aus. Allerdings haben sich aufgrund der Professionalisierung des Hochleistungssports die Risiken im kohortenspezifischen Vergleich vergrößert. (shrink)

This article examines for the first time the jihadist global hegemonic masculinity of Osama bin Laden. Based on Bin Laden’s public statements translated into English, the authors examine how in the process of constructing a rationale for violent attacks primarily against the United States, he simultaneously and discursively formulates a jihadist global hegemonic masculinity. The research adds to the growing interest in discursive global hegemonic masculinities, as well as jihadist masculinities in the Middle East, by scrutinizing how Bin Laden’s jihadist (...) global hegemonic masculinity is produced in and through his public statements. The authors close their discussion by demonstrating how Bin Laden’s discursive practices are embedded in a clash of competing global hegemonic masculinities on the world stage. (shrink)

In this paper, we argue that the concept of environmental scaffolding can contribute to a better understanding of our affective life and the complex manners in which it is shaped by environmental entities. In particular, the concept of environmental scaffolding offers a more comprehensive and less controversial framework than the notions of embeddedness and extendedness. We contribute to the literature on situated affectivity by embracing and systematizing the diversity of affective scaffolding. In doing so, we introduce several distinctions that provide (...) classifications of different types of environmentally scaffolded affectivity. Furthermore, we differentiate eight dimensions that allow us to evaluate the quality and effectivity of scaffolds in particular applications. On that basis, we develop a taxonomy using paradigmatic examples of affective scaffolding. This taxonomy enriches the current debate by emphasizing distinctions that are often conflated and by identifying fields of application that are commonly overlooked. (shrink)

We generalise the concept of clique width to structures of arbitrary signature and cardinality. We present characterisations of clique width in terms of decompositions of a structure and via interpretations in trees. Several model-theoretic properties of clique width are investigated including VC-dimension and preservation of finite clique width under elementary extensions and compactness.

The emerging consensus in the philosophy of cognition is that cognition is situated, i.e., dependent upon or co-constituted by the body, the environment, and/or the embodied interaction with it. But what about emotions? If the brain alone cannot do much thinking, can the brain alone do some emoting? If not, what else is needed? Do (some) emotions (sometimes) cross an individual's boundary? If so, what kinds of supra-individual systems can be bearers of affective states, and why? And does that make (...) emotions ?embedded? or ?extended? in the sense cognition is said to be embedded and extended? Section 2 shows why it is important to understand in which sense body, environment, and our embodied interaction with the world contribute to our affective life. Section 3 introduces some key concepts of the debate about situated cognition. Section 4 draws attention to an important disanalogy between cognition and emotion with regard to the role of the body. Section 5 shows under which conditions a contribution by the environment results in non-trivial cases of ?embedded? emotions. Section 6 is concerned with affective phenomena that seem to cross the organismic boundaries of an individual, in particular with the idea that emotions are ?extended? or ?distributed.? (shrink)

We review connections between the metric of spacetime and the quantum fluctuations of fields. We start with the finding that the spacetime metric can be expressed entirely in terms of the 2-point correlator of the fluctuations of quantum fields. We then discuss the open question whether the knowledge of only the spectra of the quantum fluctuations of fields also suffices to determine the spacetime metric. This question is of interest because spectra are geometric invariants and their quantization would, therefore, have (...) the benefit of not requiring the modding out of diffeomorphisms. Further, we discuss the fact that spacetime at the Planck scale need not necessarily be either discrete or continuous. Instead, results from information theory show that spacetime may be simultaneously discrete and continuous in the same way that information can. Finally, we review the recent finding that a covariant natural ultraviolet cutoff at the Planck scale implies a signature in the cosmic microwave background that may become observable. (shrink)

This monograph investigates the collaborative creation of scientific knowledge in research groups. To do so, I combine philosophical analysis with a first-hand comparative case study of two research groups in experimental science. Qualitative data are gained through observation and interviews, and I combine empirical insights with existing approaches to knowledge creation in philosophy of science and social epistemology. -/- On the basis of my empirically-grounded analysis I make several conceptual contributions. I study scientific collaboration as the interaction of scientists within (...) research groups. Thereby, I argue that research groups and their role in scientific practice deserve more philosophical attention than they have hitherto received. In contemporary natural science, research groups are key to the formulation and corroboration of scientific knowledge claims prior to their publication. Specifically, I suggest epistemic difference and the porosity of social structure as two conceptual leitmotifs in the study of group collaboration. With epistemic difference, I emphasize the value of socio-cognitive heterogeneity in group collaboration. With porosity, I underline the fact that a research group as social structure does not entirely contain the inter-individual efforts necessary to formulate and corroborate knowledge claims. -/- In my analysis of research groups, I focus on the division of epistemic labor among group members. Through their complementary collaborative efforts single scientists engage in relations of mutual epistemic dependence. To deepen philosophy’s understanding of scientific practice in its diversity, a distinction should be made between opaque and translucent epistemic dependence. While opaque epistemic dependence involves asymmetries in expertise, translucent epistemic dependence does not. As epistemic dependence is facilitated by trust, I investigate the dynamics of epistemic trust in group collaboration. Trust among collaborating scientists is inherently incomplete, and I show that scientists make use of diverse strategies to increase and to supplement personal trust. Based on my reflections on trust and dependence, I give an account of the relation between individual knowing and collaboratively created knowledge in research groups. Together these investigations contribute to the discussion of philosophical methodology in the study of scientific practice and promote the use of empirical methods. (shrink)

We study tree-like decompositions of models of a theory and a related complexity measure called partition width. We prove a dichotomy concerning partition width and definable pairing functions: either the partition width of models is bounded, or the theory admits definable pairing functions. Our proof rests on structure results concerning indiscernible sequences and finitely satisfiable types for theories without definable pairing functions. © 2011 WILEY-VCH Verlag GmbH & Co.

Aiming for applications in monadic second-order model theory, we study first-order theories without definable pairing functions. Our main results concern forking-properties of sequences of indiscernibles. These turn out to be very well-behaved for the theories under consideration.

Several species concepts are generally discussed and evaluated. Then the new definition, the pheno-genetic species concept, is developed; it reads: a species is the largest possible, regional evolutionary unit of pheno-genetically equal (in the typical, specific characters), identically reproducing demes. It is separated from sympatric species by a reproductive isolation that guarantees a unique evolution, an evolution different from that of other species and sufficiently uninfluenced, and that is accompanied by another distinctive pheno-genetic gap. It is separated from allopatric species (...) by a distinctive pheno-genetic gap that - in the case of missing reproductive isolation in bisexual forms — allows the conclusion that such an isolation would have developed, if the species had been sympatric with the allopatric species. This definition is applied to several situations of evolution. The effects of the concepts on the classification of lizards are demonstrated by examples. (shrink)

EPR-type measurements on spatially separated entangled spin qubits allow one, in principle, to detect curvature. Also the entanglement of the vacuum state is affected by curvature. Here, we ask if the curvature of spacetime can be expressed entirely in terms of the spatial entanglement structure of the vacuum. This would open up the prospect that quantum gravity could be simulated on a quantum computer and that quantum information techniques could be fully employed in the study of quantum gravity.
