The aim of this contribution is to provide an overview of conceptual approaches to incorporating a decision maker’s non-knowledge into economic theory. We will focus here on the particular kind of non-knowledge which we consider to be one of the most important for economic discussions: non-knowledge of possible consequence-relevant uncertain events which a decision maker would have to take into account when selecting between different strategies.

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.

Dieses Buch betritt Neuland. Es ist eine Einführung in das neue Gebiet der angewandten Ontologie, jenem multidisziplinären Arbeitsgebiet, in dem Philosophen gemeinsam mit Informatikern und Vertretern der jeweils thematischen Wissenschaftsbereiche, in unserem Fall mit Biologen und Medizinern, daran arbeiten, wissenschaftliches Wissen informationstechnisch zu repräsentieren. Es zeigt, wie Philosophie eine praktische Anwendung findet, die von zunehmender Wichtigkeit nicht nur in den heutigen Lebenswissenschaften ist. Und so richtet sich dieses Buch an Philosophen, aber auch an interessierte Biologen, Mediziner und Informatiker.

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)

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)

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.

In dit artikel wordt de dominante metafysische oriëntatie in de hedendaagse meta-ethiek kritisch onder de loep genomen. Het hedendaagse debat, dat zich voornamelijk richt op de vraag hoe moraliteit metafysisch gezien 'in de werkelijkheid past', wordt gekenmerkt door een reeks complexe en soms esoterische discussies die, zo wordt betoogd, weinig bijdragen aan ons filosofische begrip van ethiek. Deze focus op metafysische grondslagen heeft geleid tot een tunnelvisie, waarin het debat gevangen zit tussen steeds ingewikkeldere vormen van non-cognitivisme, herconceptualisaties van 'objectiviteit' (...) en metafysische acrobatiek. Als alternatief wordt voorgesteld de aandacht in de meta-ethiek te verleggen naar het domein van praktisch redeneren. Door ons te concentreren op de patronen van geldige praktische argumentatie en het soort overwegingen dat mensen daadwerkelijk overtuigt, kunnen we wellicht een beter inzicht krijgen in de aard van ethische normativiteit en de rol ervan in ons leven. Het artikel pleit voor een meer pragmatische en minder metafysisch beladen benadering van de meta-ethiek, die zich richt op de daadwerkelijke praktijken van moreel redeneren en argumenteren.

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 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.

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.

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.

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.

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)

Es gibt Staaten und Fußballmannschaften, Fakultäten und Punkbands. Und mansollte meinen, daß diese Entitäten etwas gemeinsam haben, daß sie zu ein und derselben ontologischen Kategorie gehören. Und daß sie sich unterscheiden von Elektronen, Tischen, Grizzlybären, einem Zehn-Euro-Schein, dem neuen Präsidenten, der Amtseinführung des neuen Präsidenten und der Tatsache, daß ich einen Vortrag halte. Mein Ziel ist es, zu zeigen, daß die Kategorie, die alle Beispiele der ersten Gruppe umfaßt, aber keines der zweiten Gruppe, die Kategorie der vereinten Pluralpersonen ist. Um (...) diese These stark zu machen, muß ich zunächst eine Reihe ontologischer Unterscheidungen diskutieren. Zunächst werde ich die Begriffe des Statusobjekts und des Pluralobjekts einführen, zwei relativ neue ontologische Kategorien. Sodann werde ich die traditionellen Kategorien der Substanz und der Person diskutieren, wobei ich mit Hilfe der zuvor eingeführten Begriffe des Statusobjekts und des Pluralobjekts verschiedene Arten von Personen unterscheiden werde. Die natürlichen Personen bilden nur eine dieser Arten, wenn auch die Art von Personen, zu der wir selber als Individuen gehören. Nach diesen Vorarbeiten stehen die Hilfsmittel bereit, die zu Beginn angeführten Beispiele zu kategorisieren. (shrink)

This paper undertakes a philosophical analysis of the speech given by the German writer Martin Walser when the Peace Prize of the German Book Trade was awarded to him in 1998. I reconstruct Walser's infamous claims about the Holocaust and his critique against its presence in the media and discuss Walser's proclamation of a right for disregarding his claims about German normality and his views about private commemoration.

In 'Metaphysics IX.6' (1048b 18-35) Aristotle presents a test to distinguish between "kinesis" and "energeia," based on relations between the perfective and the imperfective aspect of the verb. This passage has been interpreted as drawing a linguistic distinction between classes of verbs (e.g., stative verbs) by means of a linguistic criterion (Ackrill, Graham). But such an interpretation is in conflict with the text. Aristotle's test must, therefore, be understood as a metaphysical criterion between items in the world (rather than lingual (...) items) by means of a metaphysical criterion, exploiting properties of these items. These items are events, and 'Metaphysics IX.6' exhibits Aristotle's awareness to certain topics discussed in modern event ontology. (shrink)

Aristoteles unterscheidet zwischen zwei Arten, das Wort „dynaton" zu gebrauchen. Die erste dieser beiden Verwendungsweisen dient zur Zuschreibung von Vermögen (dynaton kata dynamin), die zweite entspricht unserer Verwendung des logisch-alethischen Modaloperators „Es ist möglich, dass" (dynaton ou kata dynamin). Ich argumentiere dafür, dass wichtige Unterschiede zwischen Vermögensprädikationen und Modalaussagen bestehen. Ich nenne mehrere Gründe dafür, dass Vermögensprädikationen keine Modalaussagen sind, zeige aber auch, dass Vermögensprädikationen zwei modale Elemente haben: Sie implizieren erstens nichttriviale Modalaussagen, weil es keine Vermögen für Unmögliches gibt. (...) Und sie implizieren zweitens nichttriviale Aussagen über kontrafaktische Situationen, weil sie Aussagen über kausale Rollen sind. (shrink)

Wether the chicken or the egg came first, is not only a mind-boggling but a substantial question. Its answer depends on the biological background theory one assumes. I review recent work on the topic (by Teichmann, Sorensen, Waller and Raatzsch) and resolve some of the disputes between these authors by borrowing from Aristotle the distinction between chicken-producing eggs. I then introduce the concept of a quasi-species to make explicit the vagueness involved in species-terms and prove 13 different priority-claims within a (...) Darwinian framework. (shrink)

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. (shrink)

This paper discusses Tugendhat's project of a "modern ethics" (moderne Moral) in contrast to "traditional ethics" (traditionelle Moral). We argue that this distinction is not as clear cut as Tugendhat would like it to be, and that Tugendhat's modern ethics shares important features with traditional ethics.

Trước những lo ngại về khí hậu toàn cầu ngày càng gia tăng, các quốc gia trên thế giới đã ký kết thỏa thuận toàn cầu nhằm thể hiện sự cam kết mạnh mẽ để chung tay tìm kiếm các giải pháp sáng tạo để giảm thiểu phát thải khí nhà kính và tác động của nó đối với môi trường. Việt Nam là một trong những thành viên tích cực tham gia và có trách nhiệm, nhưng đồng thời cũng (...) là một nước bị ảnh hưởng nặng nề nhất của biến đổi khí hậu. Nhận thấy sự cần thiết phải giải quyết vấn đề biến đổi khí hậu, Việt Nam đang triển khai nghiên cứu việc thành lập thị trường các-bon trong nước, trong đó việc xây dựng và vận hành một hệ thống lưu ký các-bon được coi là một trụ cột quan trọng, trên cơ sở học hỏi kinh nghiệm từ các mô hình trên thế giới.

The paper by Monteiro, Musten and Compson (2014) is to be commended for providing a comprehensive discussion of the compatibility issues arising from the integration of mindfulness – a 2,500-year-old Buddhist practice – into research and applied psychological domains. Consistent with the observations of various others (e.g., Dunne, 2011; Kang & Whittingham, 2010), Monteiro and colleagues have not only highlighted that there are differences in how Buddhism and contemporary mindfulness interventional approaches interpret and contextualize mindfulness, but there are also differing (...) interpretations of mindfulness within Buddhism. These apparent differences within Buddhism are arguably more noticeable when making comparisons across Buddhist vehicles (i.e., Theravada, Mahayana, Vajrayana), but to a lesser extent intra-vehicular differences can also be said to exist (i.e., differences between Buddhist traditions of the same vehicle). This commentary investigates the validity of some of these different Buddhist constructions of mindfulness, and then discusses how a better understanding of their scriptural and conceptual soundness (or lack thereof) may help to reconcile some of the actual and perceived incompatibility between Buddhist practice and contemporary secular mindfulness-based approaches.

William Whewell’s 19th century philosophy of science is sometimes glossed over as a footnote to Kant. There is however a key feature of Whewell’s account worth noting. This is his appeal to Aristotle’s form/matter hylomorphism as a metaphor to explain how mind and world merge in successful scientific inquiry. Whewell’s hylomorphism suggests a middle way between rationalism and empiricism reminiscent of experience pragmatists like Steven Levine’s view that mind and world are entwined in experience. I argue however that Levine does (...) not adequately explain exactly how mind and world entwine. He could nonetheless do so if he appealed to Whewell’s hylomorphic metaphor. We may prefer a reductive metaphysical explanation, but I suggest that pragmatists only have recourse to metaphor in this case. Both reductive and metaphorical explanations can enjoy great explanatory power if they exhibit a suitable measure of what I will call sematic distance. Semantic distance measures how close or how far apart explanandum and explanans are from each other in meaning. Metaphorical explanation - as evident in Whewell’s hylomorphism and as detailed via the notion of semantic distance - presents a valuable new explanatory tool to those who hold that mind and world are entwined sans recourse to metaphysics.

Toon van Eijk: Spinoza in het licht van bewustzijnsontwikkeling De beroemde filosoof Spinoza is moeilijk te doorgronden. Emeritus hoogleraar Maarten van Buuren heeft in 2016 twee boeken over Spinoza gepubliceerd, waarin hij diens filosofie op nauwgezette en verhelderende manier analyseert. Volgens Van Buuren is de kern van Spinoza’s ethiek de bevrijding van bevoogding en het streven om in overeenstemming te leven met de wereld en met zichzelf. Een aantal sleutelbegrippen in Spinoza’s filosofie zijn de immanente, in de natuur-inwonende God, zelfbeschikking, (...) de rede, intuïtie, macht en zelftoe-eigening. In dit boek bespreekt Toon van Eijk deze sleutelbegrippen aan de hand van de analyse van Van Buuren en de filosofie van Maharishi Mahesh Yogi, de grondlegger van de Transcendente Meditatie (TM) techniek. Filosofische begrippen blijven echter tandeloos zonder mogelijkheden om deze ideeën te verwerkelijken. Een synthese van filosofisch redeneren en praktijken voor bewustzijnsontwikkeling is nodig. Hoewel Spinoza een ethiek zonder metafysica voorstond, is Van Eijk van mening dat daadwerkelijk wijs handelen moeilijk zonder enige metafysische bagage kan. (shrink)

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.

Inspired by Bas van Fraassen’s Stance Empiricism, Anjan Chakravartty has developed a pluralistic account of what he calls epistemic stances towards scientific ontology. In this paper, I examine whether Chakravartty’s stance pluralism can exclude epistemic stances that licence pseudo-scientific practices like those found in Scientology. I argue that it cannot. Chakravartty’s stance pluralism is therefore prone to a form of debilitating relativism. I consequently argue that we need (1) some ground or constraint in relation to which epistemic stances can be (...) ranked by degrees, and (2) some way to demarcate science from pseudo-science so that we know what epistemic stances are about. Regarding (1), I argue that empirical detectability can serve as the ground in relation to which epistemic stances are ranked by degrees. Regarding (2), I argue for ranking sciences on a continuum according to established institutional criteria, rather than attempting to draw a strict demarcation. (shrink)

I identify two versions of the scientific anti-realist’s selectionist explanation for the success of science: Bas van Fraassen’s original and K. Brad Wray’s newer interpretation. In Wray’s version, psycho-social factors internal to the scientific community – viz. scientists’ interests, goals, and preferences – explain the theory-selection practices that explain theory-success. I argue that, if Wray’s version were correct, then science should resemble art. In art, the artwork-selection practices that explain artwork-success appear faddish. They are prone to radical change over time. (...) Theory-selection practices that explain theory-success in science are however not faddish. They are mostly stable; that is, long-lived and consistent over time. This is because scientists (explicitly or implicitly) subscribe to what I will call the testability norm: scientific theories must make falsifiable claims about the external physical world. The testability norm and not psycho-sociology explains the theory-selection practices that explain theory-success in science. Contra Wray, scientific anti-realists can then maintain that the external physical world (as expressed in the testability norm) explains theory-success. (shrink)

Bas van Fraassen’s Constructive Empiricism (CE) has been much discussed. There is, however, a curious feature of van Fraassen’s writings that has been overlooked up until now. This is that he sometimes capitalises certain key terms, notably “Induction”. This is done to differentiate a pragmatic small ‘i’ induction (which has epistemic import) from a rule-bound capital ‘I’ induction (which does not). In this paper, I argue that van Fraassen’s small letter/capital letter distinction reveals an underlying dualism, one that is reminiscent (...) of the notoriously problematic semantic dualism in Logical Positivism (between a theoretical language and an observation language). Despite partly developing CE to overcome Logical Positivism’s kind of dualism, van Fraassen seems to have tacitly endorsed it anyway. If so, then CE requires revision. It is, however, not clear how to conduct such a revision. It is not clear what the way forward should be once CE is understood as innately dualistic. (shrink)
