Currently, there is not yet a full-fledged philosophical sub-discipline devoted to artifacts. In order to establish such a general philosophical discourse on artifacts, two topics are of special importance: artifact functionality and artifact categorization. Both are central to the question of what artifacts are in general and in particular. This introduction first presents the current state of the art in the debates on functions, both in general and in the domain of artifacts in particular. It then unfolds the three debates relevant for artifact kinds, namely the ontological, epistemological and semantic debates on artifact categorization, and presents the most important theory options currently under scrutiny in these fields. It proceeds by introducing the contributions in this special issue on the functions and kinds of art works and other artifacts, and discusses possible perspectives for a general philosophy of artifacts.

This broad and insightful book presents current scholarship in important subfields of philosophy of science and addresses an interdisciplinary and multidisciplinary readership. It groups carefully selected contributions into the four fields of I) philosophy of physics, II) philosophy of life sciences, III) philosophy of social sciences and values in science, and IV) philosophy of mathematics and formal modeling. Readers will discover research papers by Paul Hoyningen-Huene, Keizo Matsubara, Kian Salimkhani, Andrea Reichenberger, Anne Sophie Meincke, Javier Suárez, Roger Deulofeu, Ludger Jansen, Peter Hucklenbroich, Martin Carrier, Elizaveta Kostrova, Lara Huber, Jens Harbecke, Antonio Piccolomini d'Aragona and Axel Gelfert. This collection fosters dialogue between philosophers of science working in different subfields, and brings readers the finest and latest work across the breadth of the field,illustrating that contemporary philosophy of science has successfully broadened its scope of reflection. It will interest and inspire a wide audience of philosophers as well as scholars of the natural sciences, social sciences and the humanities. The volume shares selected contributions from the prestigious second triennial conference of the German Society for Philosophy of Science/ Gesellschaft für Wissenschaftsphilosophie (GWP.2016, March 8, 2016 - March 11, 2016).

Die Zeiten, in denen der Leib-Seele-Dualismus als Ansatz der Philosophie des Geistes durch ein herrschendes Dogma als diskussionsunwürdig galt, sind vorbei. Der Dualismus darf wieder diskutiert werden. Er muß diskutiert werden, wenn in diskussionswürdiger Strenge für ihn argumentiert wird – auch wenn das, wie sich zeigen wird, manchmal ein ziemlich technisches Geschäft ist. In diesem Sinne soll im folgenden Richard Swinburnes Versuch behandelt werden, die Existenz einer Seele und damit die Wahrheit des Substanzdualismus aus einigen zunächst recht unspektakulär aussehenden Prämissen mit Hilfe der modernen Modallogik formal zu beweisen. Zugleich sei damit auf eine kleine Debatte aufmerksam gemacht, die sich inzwischen um Swinburnes Argument entwickelt hat. Die Untersuchung führt zu einem doppelten negativen Ergebnis: Zum einen sind Swinburnes Prämissen nicht plausibel, zum anderen ist ein wichtiger Teil seines Beweisversuches formal nicht in Ordnung. Swinburnes Argument ist also weder überzeugend noch gültig . Allerdings ist das nicht auf den ersten Blick ersichtlich, denn Swinburnes Argument ist alles andere als trivial. Eine eingehende Kritik dieses Arguments soll zeigen, daß, selbst wenn der Dualismus wahr sein sollte, er nicht ganz so einleuchtend ist, wie Swinburne meint

In "On Social Facts" (1989) and subsequent works, Margaret Gilbert has suggested a plural subject account of the semantics of ‘we’ that claims that a central or standard use of ‘we’ is to refer to an existing or anticipated plural subject. This contrasts with the more general approach to treat plural pronouns as expressions referring to certain pluralities. I argue that (i) the plural subject approach cannot account for certain syntactic phenomena and that (ii) the sense of intimacy, which Gilbert cites as evidence for her plural subject account, has a different source than the existence of joint commitments constituting a respective plural subject. Moreover, (iii) there is a wide varie-ty of phenomena in the linguistic record, which, while not constituting conclusive evidence against the plural subject account, nevertheless, are dealt with better by the plurality account. ‘We’ thus refers to pluralities, which may or may not be plural subjects. The precise analysis of ‘we’ thus reveals a multi-layered ontology of groups.

The 2013 Rostock Symposium on Systems Biology and Bioinformatics in Aging Research was again dedicated to dissecting the aging process using in silico means. A particular focus was on ontologies, as these are a key technology to systematically integrate heterogeneous information about the aging process. Related topics were databases and data integration. Other talks tackled modeling issues and applications, the latter including talks focussed on marker development and cellular stress as well as on diseases, in particular on diseases of kidney and skin.

This book discusses the philosophy of influential contemporary philosopher Peter van Inwagen. Looking at perennial philosophical problems from a modern point of view, Peter van Inwagen’s philosophy masterfully combines positions that have been considered irreconcilable: incompatibilism concerning free will, materialism, organicism, theism and realism concerning fictional entities. As readers will discover, his arguments are witty, surprising and deep. The book includes Peter van Inwagen’s Münster Lecture of 2015 on free will, as well as eleven papers from the Münster colloquium discussing central themes of his philosophy, and a reply to each paper by Peter van Inwagen himself. Introducing his philosophy and relating his work to other contemporary views, this book is of interest to graduate students and professionals in philosophy alike.

Given the assertion of a relation between two types, like: “Epidermis has part some Keratinocyte”, we define silent change as any kind of change of the instance-relata of the relation in question that does not change the truth-value of the respective type-level assertion. Such assertions are notoriously difficult to model in OWL 2. To address this problem, we distinguish different modes of type-level relatedness giving rise to this problem and describe a conservative extension to the BFO top-level ontology that allows expressing these modes.

A popular argument goes thus: This is a construction, hence it is not real. Adding an appropriate adjective (social, mental, human, …) in front of “construction” or cognate terms like “(legal) fiction” yields a whole family of related arguments, all of which, or so I will argue, are fallacious. Contrary to popular opinion, these arguments fail both on the epistemic and the ontic sense of construction. Ontic constructions exist at least at one point in time, while epistemic constructions may well correspond to reality. The motivation behind these fallacious arguments can often be found in a misconceived conception of ontology and reality. A full theory of reality must take constructed entities into account because important domains of reality (mental life, social reality, technical artefacts, art and fiction) essentially depend on mental or social constructions.

Margaret Gilbert has defended the claim that her plural subject theory can give a reasonable account of retrospective (or backward-looking) collective responsibility. On one occasion, publishing in this periodical, she writes that she deliberately left out the discussion of prospective (or forward-looking) collective responsibility, or the “responsibilities” of a collective. In the present paper, I want to show that plural subject theory, in fact, also allows accounting for prospective responsibilities of groups and institutions. In order to do so, I will first sketch the social ontological background of my discussion which is, in fact, an amended version of Gilbert’s theory of plural subjects (§ 2). Based on the assumption that a prospective responsibility accrues from some kind of commissioning, I will then discuss a variety of possible sources of prospective collective responsibilities: self-commissioning, third-party commissioning and what I will call commissioning by unique capability (§ 3). Having done so, I will discuss some consequences of this account and defend it against objections (§ 4).

The concept of a function is central both to biology and to technology. But there is an intricate debate how functions as well as related entities like dispositions and roles are to be represented in top level ontologies and how they are to be related. We review important philosophical accounts and ontological models for functions and roles and discuss three models for the relation of functions and dispositions. We conclude that mainly because of the need to account for malfunctioning, functions should not be treated as a subtype of dispositions, but as their sibling category.

In order to develop the ontology of tendencies for use in the representation of medical knowledge, tendencies are compared with other kinds of entities possessing the realizable-realization-structure, specifically: dispositions, propensities, abilities and virtues. The peculiarities of tendencies are discussed and a standard schema of tendency ascription is developed in order to represent the relations between the ascriptions of tendency tokens to particulars and the ascriptions of tendency types to universals. Two non-standard cases and their epistemic variants are discussed.

The construction of complex ontologies can be facilitated by adapting existing vocabularies. There is little clarity and in fact little consensus as to what modifications of vocabularies are necessary in order to re-engineer them into ontologies. In this paper we present a method that provides clear steps to follow when re-engineering a thesaurus. The method makes use of top-level ontologies and was derived from the structural differences between thesauri and ontologies as well as from best practices in modeling, some of which have been advocated in the biomedical domain. We illustrate each step of our method with examples from a re-engineering case study about agricultural fertilizers based on the AGROVOC thesaurus. Our method makes clear that re-engineering thesauri requires far more than just a syntactic conversion into a formal language or other easily automatable steps. The method can not only be used for re-engineering thesauri, but does also summarize steps for building ontologies in general, and can hence be adapted for the re-engineering of other types of vocabularies or terminologies.

Like the doctrine of the categories in general, Aristotle’s category of the relative fulfils disparate functions: On the one hand, the category of the pros ti fulfils a dialectic or logical function that aims at the avoidance of fallacies. On the other hand, the category respects the peculiar mode of being of the relative. Taking these two different functions into consideration helps with the interpretation of Aristotle’s two definitions of the relative and his treatment of the properties of the relative in Cat. 7, with the question whether corresponding relatives are of equal priority or ontologically independent, with the genus-species problem, and with the categorical classification of potency and act.

BACKGROUND The importance of ontologies in the biomedical domain is generally recognized. However, their quality is often too poor for large-scale use in critical applications, at least partially due to insufficient training of ontology developers. OBJECTIVE To show the efficacy of guideline-based ontology development training on the performance of ontology developers. The hypothesis was that students who received training on top-level ontologies and design patterns perform better than those who only received training in the basic principles of formal ontology engineering. METHODS A curriculum was implemented based on a guideline for ontology design. A randomized controlled trial on the efficacy of this curriculum was performed with 24 students from bioinformatics and related fields. After joint training on the fundamentals of ontology development the students were randomly allocated to two groups. During the intervention, each group received training on different topics in ontology development. In the assessment phase, all students were asked to solve modeling problems on topics taught differentially in the intervention phase. Primary outcome was the similarity of the students’ ontology artefacts compared with gold standard ontologies developed by the authors before the experiment; secondary outcome was the intra-group similarity of group members’ ontologies. RESULTS The experiment showed no significant effect of the guideline-based training on the performance of ontology developers (a) the ontologies developed after specific training were only slightly but not significantly closer to the gold standard ontologies than the ontologies developed without prior specific training; (b) although significant differences for certain ontologies were detected, the intra-group similarity was not consistently influenced in one direction by the differential training. CONCLUSION Methodologically limited, this study cannot be interpreted as a general failure of a guideline-based approach to ontology development. Further research is needed to increase insight into whether specific development guidelines and practices in ontology design are effective.

Is a bank note identical with the piece of paper of which it consists? On the one hand, John Searle, in his reply to Barry Smith, suggests that they are “one and the same object” that is a social or non-social object only under certain descriptions. On the other hand, Lynne Rudder Baker puts forward the claim that bank note and paper are distinct entities that are bound together by the relation of material constitution. I suggest two possible analyses for Searle’s description relativity claim, the Alternative Subject Analysis and the Predicate Modification Analysis. On both accounts his identity claim gets into serious trouble. While Baker’s definition of material constitution deals well with the bank note example, it fails to account for the constitution of bearerless social entities and groups. I point out five respects in which social constitution can differ from Baker’s account of material constitution and discuss compositional, institutional and interactional constitution as additional varieties of social constitution.

After a short sketch of Lowe’s account of his four basic categories, I discuss his theory of formal ontological relations and how Lowe wants to account for dispositional predications. I argue that on the ontic level Lowe is a pan-categoricalist, while he is a language dualist and an exemplification dualist with regard to the dispositional/categorical distinction. I argue that Lowe does not present an adequate account of disposition. From an Aristotelian point of view, Lowe conflates dispositional predication with hôs epi to poly statements about what is normally or mostly the case
