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. (shrink)

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. (shrink)

Sparrows fly because they are birds. This mushroom is poisonous because it is an Amanita muscaria. Pointing out the kind to which things belong explains many of their properties. Jonathan Lowe’s four-category ontology and his account of laws of nature provide a framework to account for the explanatory appeal of referring to kind membership. For Lowe, “Electron has Unit-negative charge” is a typical example for a law of nature: a kind universal characterized by a property universal. We present both Lowe’s (...) original account of laws of nature and later developments, and show how Lowe’s account can help to solve notorious problems of other accounts, namely, the regularity view and the Armstrong-Dretske-Tooley view. We argue that there are two challenges that Lowe’s view cannot master. First, Lowe conflates generics and dispositions, which is a considerable problem for Lowe, because his account of dispositional predication and his account of laws of nature are intimately connected. Second, there is the identification problem of fully specifying and identifying the formal ontological relation of characterization between kind universals and property universals. In order to solve these problems, we develop an account of formal causation inspired by Aristotle’s theory of explanation in his Posterior Analytics. Though very close to Lowe’s own account, our neo-Aristotelian account avoids Lowe’s confusion regarding dispositions, avoids overdetermination through several similar laws of nature, and provides an answer to the identification problem: The characterization of a kind universal by a property universal constitutes the relation of formal causation. By virtue of this relation, the kind Amanita muscaria is the formal cause of this mushroom having the attribute of being poisonous. (shrink)

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. (shrink)

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.

In recent years CL diagrams inspired by Lange’s Cubus Logicus have been used in various contexts of diagrammatic reasoning. However, whether CL diagrams can also be used as a formal system seemed questionable. We present a CL diagram as a formal system, which is a fragment of propositional logic. Syntax and semantics are presented separately and a variant of bitstring semantics is applied to prove soundness and completeness of the system.

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.

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 nonstandard cases and their epistemic variants are discussed.

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.

Much work in social ontology analyzes how social entities are based on collective intentionality. A neglected perspective is, however, the distinction between those social entities that are explicitly established (often called formal institutions, like marriages), those that are established but not explicitly (informal institutions, like friendships), and those that are not established at all (social macro entities, like episodes of inflation). To shed more light on this trichotomy, a collection of examples taken from the works of John Searle will be (...) discussed, comprising money, marriages, friendship, cocktail parties, natural language, and episodes of inflation. The chapter argues that explicit establishment confers certain typical characteristics on formal institutions that informal institutions lack, thus explaining the typical differences between marriages and friendship. The focus on explicit establishment further develops Khalidi’s classification of social kinds, and it contributes to Epstein’s quest for grounds and anchors of social entities. It can thus contribute to overcoming the narrow focus on collective intentionality. (shrink)

Functional explanations apply not only in cases of normal functioning, but also in the case of malfunctioning. According to a straightforward analysis, a bearer of the function to F is malfunctioning if and only if it does not F although it should do so. This makes malfunctions and malfunctionings analogous to negative causation and thus peculiarly problematic, because they seem to involve absent dispositions and absent processes. This analysis seems also to require that the function to F cannot be identical (...) with the disposition to F. Then we seem to be trapped in a dilemma: Either the realm of functions is separated from the realm of dispositions; then it seems that functions cannot be causally efficacious. Alternatively, functions are considered to be identical with dispositions; but then malfunctioning seems to be conceptually impossible. The paper defends and further develops the thesis of Röhl and Jansen that functions are not a special type of dispositions. For this purpose, it first reviews different varieties of malfunction and malfunctioning and suggests definitions of both malfunction and malfunctioning. It reviews how causal, etiological and intentional theories of functions can deal with these problems. In particular, the paper discusses the special-disposition account of the Basic Formal Ontology. Spear, Ceusters and Smith :103--128, 2016) have defended the special-disposition account of the Basic Formal Ontology by suggesting various strategies how a special-disposition account can deal with malfunctions. On the one side, the paper evaluates these strategies and indicates several problems arising from them. On the other hand, it describes how to account for the non-optionality and the causal efficacy of functions, if functions are not dispositions. While function types are not identical to disposition types, there are important interrelations between functions and dispositions, namely heuristically, from a design perspective for artefact functions, and from an evolutionary perspective for types of biological functions.

Being an "untimely review", this paper reviews Aristotle's 'Categories' as if they were published today, in the era of computerised information, where categorisation becomes more and more essential for information retrieval. I suggest a systematic ordering of Aristotle's list of categories and argue that Aristotle's discussion of ontological dependency and his focus on concrete entities are still a source of new insight and can indeed be read as a contribution to the emerging field of applied ontology and ontological engineering.

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). (shrink)

With substance dualism and the existence of God, Swinburne (2004, The Existence of God, Oxford University Press, Oxford) and Moreland (2010, Consciousness and the Existence of God, Routledge, New York) have argued for a very powerful explanatory mechanism that can readily explain several philosophical problems related to consciousness. However, their positions come with presuppositions and ontological commitments which many are not prepared to share. The aim of this paper is to improve on the Swinburne-Moreland argument from consciousness by developing an (...) argument for the existence of God from consciousness without being committed to substance dualism. The argument proceeds by suggesting a solution to the exceptional-point-of-view problem, i.e., the question how it can be explained that there is a conscious being lucky enough to experience the point of view of a relatively tiny brain amidst a giant universe that is indifferent about which physical entities it brings about according to the laws of physics.

It has long been a standard practice for the natural sciences to classify things. Thus, it is no wonder that, for two and a half millennia, philosophers have been reflecting on classifications, from Plato and Aristotle to contemporary philosophy of science. Some of the results of these reflections will be presented in this chapter. I will start by discussing a parody of a classification, namely: the purportedly ancient Chinese classification of animals described by Jorge Luis Borges. I will show that (...) many of the mistakes that account for the comic features of this parody appear in real-life scientific databases as well. As examples of the latter, I will discuss the terminology database of the National Cancer Institute (NCI) of the United States, the NCI Thesaurus. (shrink)

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.

The constituents of social entities (and of social continuants in particular) determine whether or not a social thing comes to be, persists and perishes. John Searle hints at two very different accounts for the persistence of social entities, a mere past related account and an acceptance theoretic account, whereas Margaret Gilbert's account is based on deontic entities like obligations or joint commitments. I demonstrate that Gilbert's account can also accommodate Searle's examples. While oblivion, protests or violence can be historical causes (...) of the destruction of social entities, they cannot be considered to be the ultimate causes of the perishing from Gilbert's point of view. Social entities rather perish because of the treatises or divorces that dissolve their deontic constituents. (shrink)

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 -/- In biomedical ontologies, mereological relations have always been subject to special interest due to their high relevance in structural descriptions of anatomical entities, cells, and biomolecules. This paper investigates two important subrelations of has_proper_part, viz. the relation has_grain, which relates a collective entity to its multiply occurring uniform parts (e.g., water molecules in a portion of water), and the relation has_component, which relates a compound to its constituents (e.g., molecules to the atoms they consist of). -/- METHOD -/- (...) We distinguish between four kinds of complex entities and characterize them in first order logic. We then discuss whether similar characterizations could be given in description logics, and finally apply the results to mixtures. -/- RESULTS -/- At first sight, collectives and compounds seem to be disjoint categories. Their disjointness, however, relies on agreement about what are uniform entities, and thus on the granularity of description. For instance, the distinction between isomeric subtypes of a molecule can be important in one use case but might be neglected in another one. We demonstrate that, as implemented in the BioTop domain upper level ontology, equivalence or subsumption between different descriptions of same or similar entities cannot be achieved. Using OWL-DL, we propose a new design pattern that avoids primitive subrelations at the expense of more complex descriptions and thus supports the needed inferences. (shrink)

Taking Thomas Aquinas's interpretation of the prologue of St John's gospel (in his Lectura super loannem Evangelium) as example, I first discuss eight differences between medieval biblical interpretation and modern exegesis, especially Aquinas's frequent use of philosophical opinions in interpreting the Bible, taken mostly from Aristotle. Second, I account for these differences by reconstructing Aquinas's hermeneutics, hinging, as is shown, upon the assumption that scripture was authored by God infallible and, therefore, only contains true statements. From this starting point Aquinas (...) is lead to a holistic hermeneutics: The interpretation of a biblical statement can be judged on only within the context of an entire theory of God, the world, and of the interpretation of the other biblical statements. Thirdly, this view is discussed systematically and critically. (shrink)

No one influenced and shaped our thinking about dispositions and causal properties more than Aristotle. What he wrote about power (dynamis), nature (physis) and habit (hexis) has been read, systematised and criticised again and again during the history of philosophy. In this chapter I sketch Aristotle's thoughts about dispositions and argue that his theory can still be regarded as a good one.

Starting from the early treatise "On Being and Essence", I review issues concerning substances composed of matter and form: their hylomorphic composition, individuation, essence as part and as whole, and the analogy between genus/difference and matter/form. Then I discuss substances separated from matter, which may range from human souls and angels (or intelligences) to God. I then turn to Aquinas's later 'Summa Theologica', where he argues that in the end God cannot possibly belong to the category of substance and discuss (...) possible reasons for Aquinas conflicting accounts on this question.

The so-called materially valid inferences have come to new prominence through the work of Robert Brandom. This paper introduces a fragment of a logic of concepts that does not reduce concepts to their extensions. Concept logic and ist semantics allow us to represent the conceptual knowledge used in material inferences and thus suggests a way to deal with them.

Zuweilen werden der Geschichtsschreibung der Wissenschaftscharakter und historischen Aussagen die Wahrheitsfähigkeit abgesprochen. Ich werde erstens zeigen, dass Aussagen über Vergangenes nicht nur wahrheitsfähig sind, sondern dass einige Aussagen über Vergangenes tatsächlich wahr sind. Zweitens argumentiere ich dafür, dass weder die Gebundenheit an Quellen und die Möglichkeit des Irrtums, noch die Zeit- und Standortgebundenheit historischer Aussagen und eine eventuelle Werthaltigkeit historischer Urteile eine zwingende Gefahr für den Wissenschaftscharakter der Geschichtsschreibung sind. Sie stellen aber besondere Ansprüche an die wissenschaftlichen Tugenden, die ein (...) guter Historiker besitzen muss. Drittens zeige ich, dass die Suche nach historischer Wahrheit nicht nur möglich, sondern für ein funktionierendes gesellschaftliches Zusammenleben auch von größter Bedeutung ist. (shrink)

There are group-actions, and if actions are intentional, there should also be group-intentions. Who has got these intentions? The groups? This seems to be the natural answer. But then: Groups do not have a mind or brain of there own to form any mental attitude. Different kinds of individualistic analyses of group-intentions have been suggested in the literature. On the one hand there are suggestions to reduce group intentions to a complex of different Iattitudes. John Searle, on the other hand, (...) suggests a special social kind of attitudes, namely we-intentions. We-intentions are being had by individual persons, though they have the form “We intend to do such-and-such”. However, because of the fallibility of Searlian we-intentions and the possibility of ignorance this concept is of no help: We-intentions are neither necessary nor sufficient for group-intentions. In this respect, Margaret Gilbert’s approach is much more successful, though it covers only a special case, namely small-scale informal groups. I suggest a generalised solution in order to cover also large-scale and formal groups. (shrink)
