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.

Alison Bailey’s The Weight of Whiteness: A Feminist Engagement with Privilege, Race, and Ignorance examines how whiteness misshapes our humanity, measuring the weight of whiteness in terms of its costs and losses to collective humanity. People of color feel the weight of whiteness daily. The resistant habits of whiteness and its attendant privileges, however, make it difficult for white people to feel the damage. White people are more comfortable thinking about white supremacy in terms of what privilege does for (...) them, rather than feeling what it does to them. The first half of the book focuses on the overexposed side of white privilege, the side that works to make the invisible and intangible structures of power more visible and tangible. Bailey discusses the importance of understanding privileges intersectionally, the ignorance-preserving habits of “white talk,” and how privilege and ignorance circulate in educational settings. The second part invites white readers to explore the underexposed side of white dominance, the weightless side that they would rather not feel. The final chapters are powerfully autobiographical. Bailey engages readers with a deeply personal account of what it means to hold space with the painful weight of whiteness in her own life. She also offers a moving account of medicinal genealogies, which helps to engage the weight she inherits from her settler colonial ancestors. The book illustrates how the gravitational pull of white ignorance and comfort are stronger than the clean pain required for collective liberation. The stakes are high: Failure to hold the weight of whiteness ensures that white people will continue to blow the weight of historical trauma through communities of color. -/- All rights reserved.

Abstract: If anger is the emotion of injustice, and if most injustices have prominent epistemic dimensions, then where is the anger in epistemic injustice? Despite the question my task is not to account for the lack of attention to anger in epistemic injustice discussions. Instead, I argue that a particular texture of transformative anger – a knowing resistant anger – offers marginalized knowers a powerful resource for countering epistemic injustice. I begin by making visible the anger that saturates the silences (...) that epistemic injustices repeatedly manufacture and explain the obvious: silencing practices produce angry experiences. I focus on tone policing and tone vigilance to illustrate the relationship between silencing and angry knowledge management. Next, I use María Lugones’s pluralist account of anger to bring out the epistemic dimensions of knowing resistant anger in a way that also calls attention to their histories and felt textures. The final section draws on feminist scholarship about the transformative power of angry knowledge to suggest how it might serve as a resource for resisting epistemic injustice. (shrink)

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.

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.

Many say that ontological disputes are defective because they are unimportant or without substance. In this paper, we defend ontological disputes from the charge, with a special focus on disputes over the existence of composite objects. Disputes over the existence of composite objects, we argue, have a number of substantive implications across a variety of topics in metaphysics, science, philosophical theology, philosophy of mind, and ethics. Since the disputes over the existence of composite objects have these substantive implications, they are (...) themselves substantive. (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)

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)

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)

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.

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)

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)

In this paper I offer a new interpretation of Stoic ontology. I aim to explain the nature of, and relations between, (i) the fundamental items of their physics, bodies; (ii) the incorporeal items about which they theorized no less; and (iii) universals, towards which the Stoic attitude seems to be a bizarre mixture of realism and anti-realism. In the first half of the paper I provide a new model to explain the relationship between those items in (i) and (ii). This (...) model clears up several problems in Stoicism and gives a precise answer to the question of how bodies and incorporeals differ in their mode of being. The second half of the paper considers the vexed issue of the status of those items in (iii), Stoic universals. (shrink)

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)

Social justice demands that we attend carefully to the epistemic terrains we inhabit as well as to the epistemic resources we summon to make our lived experiences tangible to one another. Not all epistemic terrains are hospitable—colonial projects landscaped a good portion of our epistemic terrain long before present generations moved across it. There is no shared epistemicterra firma,no level epistemic common ground where knowers share credibility and where a diversity of hermeneutical resources play together happily. Knowers engage one another (...) on a politically saturated,unlevel knowing fieldwhere members of dominant groups work to forcibly maintain their epistemic home-terrain advantage. I use the metaphor of the unlevel knowing field to capture these oppressive epistemic structures. The unlevel knowing field is a hungry place where all knowledge that fails to nurture and sustain dominant ways knowing risks being dragged onto the dominator's epistemic home turf to be mined, coopted, consumed, or destroyed. Knowledge and willful ignorance circulate with equal vigor in this hungry world. From the standpoint of oppressed/resisting peoples, the unlevel knowing field is a minefield, an epistemic twilight zone, which must be traversed with considerable care and endless attention. The harms epistemic injustice produces are not disembodied harms. Repeated acts of injustice weather our bodies, dull our minds, weaken our hearts, and traumatize the spirit of our communities. They create public-health precarities and invite mental, emotional, physical, and spiritual illness into our being. Epistemic oppression is a cruel thief. It is disorienting, exhausting, and deadly. It triggers anger, anxiety, depression, and resistance. It steals our time, energy, and attention away from more beautiful things. (shrink)

Book Panel on Zoopolis including articles by Clare Palmer, Dinesh Wadiwel and Laura Janara and a reply by Donaldson and Kymlicka.

Pronouns often convey information about a person’s social identity (e.g., gender). Consequently, pronouns have become a focal point in academic and public debates about whether pronouns should be changed to be more inclusive, such as for people whose identities do not fit current pronoun conventions (e.g., gender non-binary individuals). Here, we make an empirical contribution to these debates by investigating which social identities lay speakers think that pronouns should encode and why. Across four studies, participants were asked to evaluate different (...) types of real and hypothetical pronouns, including binary gender pronouns, race pronouns, and identity-neutral pronouns. We sampled participants from two languages with different pronoun systems: English (N = 1,120) and Turkish (N = 260). English pronouns commonly denote binary gender (e.g., he for men), whereas Turkish pronouns are identity-neutral (e.g., o for anyone). Participants’ reasoning about pronouns reflected both a familiarity preference (i.e., participants preferred the pronoun type used in their language) and—critically—participants’ social ideologies. In both language contexts, participants’ ideological beliefs that social groups are inherently distinct (essentialism) and should be hierarchal (social dominance orientation) predicted relatively greater endorsement of binary gender pronouns and race pronouns. A preregistered experimental study with an English-speaking sample showed that the relationship between ideology and pronoun endorsement is causal: Ideologies shape attitudes toward pronouns. Together, the present research contributes to linguistic and psychological theories concerning how people reason about language and informs policy-relevant questions about whether and how to implement language changes for social purposes.

In this article, we describe what cryptocurrency is, how it works, and how it relates to familiar conceptions of and questions about money. We then show how normative questions about monetary policy find new expression in Bitcoin and other cryptocurrencies. These questions can play a role in addressing not just what money is, but what it should be. A guiding theme in our discussion is that progress here requires a mixed approach that integrates philosophical tools with the purely technical results (...) of disciplines like computer science and economics. Note: this article is the first entry within a two-part sequence on the Philosophy, Politics, and Economics of Cryptocurrency. (shrink)

Classrooms are unlevel knowing fields, contested terrains where knowledge and ignorance are produced and circulate with equal vigor, and where members of dominant groups are accustomed to having an epistemic home-terrain advantage. My project focuses on one form of resistance that regularly surfaces in discussions with social-justice content. Privilege-preserving epistemic pushback is a variety of willful ignorance that many members of dominant groups engage in when asked to consider both the lived and structural injustices that members of marginalized groups experience (...) daily. I argue that this dominant form of resistance is neither an expression of skepticism nor a critical-thinking practice. I suggest that standard philosophical engagements with these expressions of resistance are incapable of tracking the harms of privilege-preserving epistemic pushback. I recommend treating this pushback as a “shadow text,” that is, as a text that runs alongside the readings in ways that offer no epistemic friction. I offer this as one critical philosophical practice for making students mindful of the ways they contribute to the circulation of ignorance and epistemic violence during the course of their discussions.

I examine two startling claims attributed to some philosophers associated with Megara on the Isthmus of Corinth, namely: Ml. Something possesses a capacity at t if and only if it is exercising that capacity at t. M2. One can speak of a thing only by using its own proper A6yor;. In what follows, I will call the conjunction of Ml and M2 'Megaricism' .1 The lit­ erature on ancient philosophy contains several valuable discussions of Ml and M2 taken individually .2 (...) But there is no discussion of them together, much less of their logical relations. I intend to remedy that lack, and to show why it is a lack worth remedying. My aims are both philosophical and historical. Inevitably, in saying anything new and interesting about Megaric views, I will be adopting assumptions scarcely free from controversy, and indulging in quite a bit of charitable recon­ struction. But the resulting picture is of considerable interest. For it explains why, although Ml and M2 seem to have little to do with one another, it is in fact small wonder that anyone who held one would hold the other, for, as I attempt to show, they entail each other. It explains why the Megarics are associated in the primary literature with the names of such diverse philosophical ancestors as Parmenides and Protagoras. And it explains why, although they are both false, Ml and M2 were claims taken seriously by both Plato and Aristotle, who in developing their own views on modality and language saw reason to mention Megaricism, and to argue against it.

This chapter weighs a challenge to the attractive notion that by enabling empathy, fiction affords wide-ranging knowledge of what others’ experiences are like. It is commonly held that ‘seeing the world through others’ eyes’ often requires the empathizer to undergo an imaginative shift in sensibility, and we might naturally think that fiction helps us to effect that shift. However, some recent work on empathy and imagination encourages the conclusion that we are actually rigidly restricted to our own sensibilities even in (...) the wildest flights of imagination great literature can inspire. Drawing on the work of the novelist Zadie Smith, the chapter argues that while our imaginative capacities are not entirely unconstrained by our sensibilities, fiction can still help us to learn about a wide range of human experiences, including the experiences of people whose sensibilities substantially diverge from our own. Notably, fiction can work on our patterns of attention in such a way that we become temporarily ‘not ourselves.’. (shrink)

My engagement with Dotson’s essay begins with an overview of first- and second-order epistemic exclusions. I develop the concept of an "unlevel knowing field." I use examples from the epistemic injustice literature, and some of my own, to highlight the important distinction she makes between reducible and irreducible forms of epistemic oppression. Next, I turn my attention to her account of third-order epistemic exclusions. I offer a brief explanation of why her sketch of at this level makes an important contribution (...) to the literature on epistemic injustice. In closing I suggest that Dotson’s account of third-order epistemic exclusions has a cognitive bend that limits the resources she might use for bringing about change, and suggest opening up the conversation to include affective, aesthetic or mystical resources.

Paper presented at the Heidegger Circle 2011. Although Aristotle’s influence on young Heidegger’s thought has been studied at length, such studies have almost exclusively focused on his interpretation of Aristotle’s ethics, physics and metaphysics. I will rather address Heidegger’s appropriation of Aristotle’s ontology of life. Focusing on recently published or recently translated courses of the mid 20’s (mainly SS 1924, WS 1925-26 and SS 1926), I hope to uncover an important aspect of young Heidegger’s thought left unconsidered: namely, that Dasein’s (...) existential structures – Befindlichkeit, Understanding and being-with-one-another through language – arose from his close reading of Aristotle’s ontology of life, of animal life.

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.

Sara Ruddick's contemporary philosophical account of mothering reconsiders the maternal arguments used in the women's peace movements of the earlier part of this century. The culmination of this project is her 1989 book, Maternal Thinking: Toward a Politics of Peace. Ruddick's project is ground-breaking work in both academic philosophy and feminist theory. -/- In this chapter, I first look at the relationship between the two basic components of Ruddick's argument in Maternal Thinking: the "practicalist conception of truth" (PCT) and feminist (...) standpoint theory (FST). I argue that Ruddick is never clear about the exact relation between the two components. These tensions point to a deeper problem in Ruddick's discussion of the critical power of maternal thinking. -/- The diversity of maternal practices presents a genuine challenge to Ruddick’s account. I argue that neither of the components she explores can adequately ground a feminist peace politics without first answering the question of who speaks for mothers. While I can suggest ways to make Ruddick's argument consistent, she still faces-despite her claims of universality- the deeper problem of reconciling her account of maternal practice with the genuine diversity of actual maternal practices.

It is no accident that white privilege designed to be both be invisible and weightless to white people. Alison Bailey’s “On White Privilege and Anesthesia: Why Does Peggy McIntosh’s Knapsack Feel Weightless?” extends a weighty invitation white readers to complete the unpacking task McIntosh (1988) began when she compared white privilege to an “invisible and weightless knapsack.” McIntosh focuses primarily making white privilege visible to white people. Bailey’s project continues the conversation by extending a ‘weighty invitation’ to white (...) readers to explore why the metaphorical knapsack, despite the weight of its contents, feels weightless. Here’s the short answer. The knapsack only feels weightless because white people have become anesthetized us to our own brokenness. We are more comfortable considering what white privilege does for us than what it does to us. People of color feel the weight of whiteness every day. The weighty invitation invites white readers to become sensitive to our own insensitivity. To do this Bailey (1) explores white resistance to unpacking the weight; (2) people of color’s testimonies to the daily impact of the weight on their bodies; and (3) how the anesthesia of white privilege distorts our humanity. The article concludes with a McIntosh style list of that the anesthesia of privilege distorts white people’s humanity. (shrink)

In this paper, I use a comparative analysis of mysticism in Zen and the Abrahamic faiths to formulate a phenomenological account of mysticism “as such.” I argue that, while Zen Buddhism is distinct from other forms of mystical experience in important ways, it can still be fit into a general phenomenological category of mystical experience. First, I explicate the phenomenological accounts of mysticism provided by Anthony Steinbock and Angela Bello. Second, I offer an account of Zen mysticism which both coheres (...) with and problematizes these accounts, arguing that Zen demonstrates the inadequacy of these accounts as descriptions of mysticism as a universal religious category. Lastly, I use this investigation to propose that Zen mysticism does generally cohere with the mystical experiences of other religions, but only if we devise a new formula for speaking phenomenologically about mystical experience as such which captures this phenomenon in all of its manifestations.

My contribution to this conversation sets out to accomplish two things: First, I offer a definition of epistemic pushback. Epistemic pushback is an expression of epistemic resistance that occurs regularly in classroom discussions that touch our core beliefs, sense of self, politics, or worldv iews. Epistemic pushback is structural: It broadly characterizes a family of cognitive, affective, and verbal tactics that are deployed regularly to dodge the challenging and exhausting chore of engaging topics and questions that scare us. It can (...) take such forms as direct deep hostility, knee jerk skepticism, or silence. Good teaching should not only track the production of knowledge, but also the production of ignorance. There are forms of epistemic pushback that are ignorance producing, so I work with students to cultivate a mindfulness around epistemic pushback by treating it as a ‘shadow text.’ The remainder of the paper explains the nature of shadow texts, and offers suggestions for how to navigate them.

In the Republic Plato contrasts dialectic with mathematics on the grounds that the former but not the latter gives justifications of some kind for its hypotheses, pursuing this process until it reaches ‘an unhypothetical principle’. But which principles are unhypothetical, and why, is rather dark. One reason for this is the scarcity of forms of that precious word, ‘unhypothetical’ (aνυπoθετος), used only twice by Plato (Rep. 510 b 7, 511 b 6) and just once by Aristotle (Metaph. 1005B14). But that (...) very scarcity also suggests the intriguing possibility that Aristotle has Plato’s text in mind when he uses the word, so we might expect to understand Plato better by grasping how Aristotle took him. That is a notoriously defeasible assumption since plenty of modern accounts of Plato want to save him from Aristotle’s numerous critiques, and hence imply that the master of them that know frequently missed the point when it came to his own master. But surely we can be more confident that Aristotle will give us access to Plato when it appears not merely that he is dealing with the same topic, but using the same rare vocabulary to boot. Hence the understandable temptation to turn to Metaphysics Γ for help in identifying Platonic unhypothetical principles. I shall argue that Aristotle is indeed thinking of Plato’s text when he uses the word for ‘unhypothetical’, and further that what is explicitly an unhypothetical principle for Aristotle might well have been one for Plato too. But later I shall claim that their joint use of a much more common word in the same philosophical context is either coincidence or misunderstanding on Aristotle’s part, for he must mean something different by it from what Plato means.

George Yancy's interview with Alison Bailey addresses what it means for Whites to be "privilege-cognizant but metaphysically comfortable.” .

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)

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.

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.

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.

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)
