Advanced AI systems are rapidly making their way into medical research and practice, and, arguably, it is only a matter of time before they will surpass human practitioners in terms of accuracy, reliability, and knowledge. If this is true, practitioners will have a prima facie epistemic and professional obligation to align their medical verdicts with those of advanced AI systems. However, in light of their complexity, these AI systems will often function as black boxes: the details of their contents, calculations, (...) and procedures cannot be meaningfully understood by human practitioners. When AI systems reach this level of complexity, we can also speak of black-box medicine. In this paper, we want to argue that black-box medicine conflicts with core ideals of patient-centered medicine. In particular, we claim, black-box medicine is not conducive for supporting informed decision-making based on shared information, shared deliberation, and shared mind between practitioner and patient.

In this paper, we present and defend an analysis of harm that we call the Negative Influence on Well-Being Account (NIWA). We argue that NIWA has a number of significant advantages compared to its two main rivals, the Counterfactual Comparative Account (CCA) and the Causal Account (CA), and that it also helps explain why those views go wrong. In addition, we defend NIWA against a class of likely objections, and consider its implications for several questions about harm and its role (...) in normative theorizing. (shrink)

The essays in this volume investigate the question of where, and in what sense, the bounds of intelligible thought, knowledge, and speech are to be drawn. Is there a way in which we are limited in what we think, know, and say? And if so, does this mean that we are constrained—that there is something beyond the ken of human intelligibility of which we fall short? Or is there another way to think about these limits of intelligibility—namely, as conditions of (...) our meaning and knowing anything, beyond which there is no specifiable thing we cannot do? -/- These issues feature prominently in the writings of Kant and Wittgenstein who each engaged with them in unique and striking ways. Their thoughts on the matter remain provocative and stimulating, and accordingly the contributions to this volume address the issues surrounding the limits of intelligibility both exegetically and systematically: they examine how they figure in Kant’s and Wittgenstein’s most significant works and put them in touch with contemporary debates that are shaped by their legacy. These debates concern, inter alia, logically and morally alien thought, the semantics and philosophy of negation, disjunctivism in philosophy of perception and ethics, paraconsistent approaches to contradiction, and the relation between art, literature, and philosophy. The book is divided into four parts: Part I gives a first assessment of the issues, Part II examines limits as they feature in Kant, Part III as they feature in Wittgenstein, and Part IV suggests some ways in which the questions at issue might be reconsidered, drawing upon ideas in phenomenology, dialetheism, metamathematics, and the works of other influential authors. -/- Limits of Intelligibility provides insight into a theme that is central to the thought of two of the most important figures in modern philosophy, as well as to recent metaphysics, philosophy of language, philosophy of logic, epistemology, and ethics.

The paper examines Schopenhauer’s complex diagrams from the Berlin Lectures of the 1820 s, which show certain partitions of classes. Drawing upon ideas and techniques from logical geometry, we show that Schopenhauer’s partition diagrams systematically give rise to a special type of Aristotelian diagrams, viz. (strong) α -structures.

In this paper we explore the potential bearing of the extended mind thesis—the thesis that the mind extends into the world—on epistemology. We do three things. First, we argue that the combination of the extended mind thesis and reliabilism about knowledge entails that ordinary subjects can easily come to enjoy various forms of restricted omniscience. Second, we discuss the conceptual foundations of the extended mind and knowledge debate. We suggest that the theses of extended mind and extended knowledge lead to (...) a bifurcation with respect to the concepts of belief and knowledge. We suggest that this conceptual bifurcation supports a form of pluralism about these concepts. Third, we discuss whether something similar can be said at the metaphysical level. (shrink)

In this paper, I investigate whether we can use a world-involving framework to model the epistemic states of non-ideal agents. The standard possible-world framework falters in this respect because of a commitment to logical omniscience. A familiar attempt to overcome this problem centers around the use of impossible worlds where the truths of logic can be false. As we shall see, if we admit impossible worlds where “anything goes” in modal space, it is easy to model extremely non-ideal agents that (...) are incapable of performing even the most elementary logical deductions. A much harder, and considerably less investigated challenge is to ensure that the resulting modal space can also be used to model moderately ideal agents that are not logically omniscient but nevertheless logically competent. Intuitively, while such agents may fail to rule out subtly impossible worlds that verify complex logical falsehoods, they are nevertheless able to rule out blatantly impossible worlds that verify obvious logical falsehoods. To model moderately ideal agents, I argue, the job is to construct a modal space that contains only possible and non-trivially impossible worlds where it is not the case that “anything goes”. But I prove that it is impossible to develop an impossible-world framework that can do this job and that satisfies certain standard conditions. Effectively, I show that attempts to model moderately ideal agents in a world-involving framework collapse to modeling either logical omniscient agents, or extremely non-ideal agents. (shrink)

The Groundwork of the Metaphysics of Morals is Kant's central contribution to moral philosophy, and has inspired controversy ever since it was first published in 1785. Kant champions the insights of 'common human understanding' against what he sees as the dangerous perversions of ethical theory. Morality is revealed to be a matter of human autonomy: Kant locates the source of the 'categorical imperative' within each and every human will. However, he also portrays everyday morality in a way that many readers (...) find difficult to accept. The Groundwork is a short book, but its argument is dense, intricate and at times treacherous. This commentary explains Kant's arguments paragraph by paragraph, and also contains an introduction, a synopsis of the argument, six short interpretative essays on key topics of the Groundwork, and a glossary of key terms. It will be an indispensable tool for anyone wishing to study the Groundwork in detail. (shrink)

Ein Beispiel für die Rezeption und Fortführung der schopenhauerschen Logik findet man in den Mathematiklehrbüchern Friedrich Adolph Wilhelm Diesterwegs (1790–1866), In diesem Aufsatz werden die historische und systematische Dimension dieser Anwendung von Logikdiagramme auf die Mathematik skizziert. In Kapitel 2 wird zunächst die frühe Rezeption der schopenhauerschen Logik und Philosophie der Mathematik vorgestellt. Dabei werden einige oftmals tradierte Vorurteile, die das Werk Schopenhauers betreffen, in Frage gestellt oder sogar ausgeräumt. In Kapitel 3 wird dann die Philosophie der Mathematik und der (...) Logik Schopenhauers vorgestellt. Es wird gezeigt, dass Schopenhauers Logikdiagramme auf Ideen der Mathematiker Leonhard Euler (1707–1783), Bernhard Friedrich Thibaut (1775–1832) und Franz Ferdinand Schweins (1780–1856) zurückgehen und dass Schopenhauer diese Logikdiagramme auch bereits zur Analyse mathematischer Begriffe verwendet. Kapitel 4 beschäftigt sich mit der Schopenhauer-Rezeption Diesterwegs. Es wird die Frage behandelt, inwieweit Diesterweg in der Mathematik von Schopenhauer beeinflusst war und welche Rolle dieser Einfluss auf sein Verständnis von Logik und Mathematik hatte. In Kapitel 5 wird schließlich gezeigt, dass Diesterweg die schopenhauersche Begriffsanalyse der Mathematik mit Hilfe von Logikdiagrammen aufgreift und weiterführt. Da Diesterweg einer der einflussreichsten Pädagogen und Mathematikdidaktiker des 20. Jahrhunderts war, ist anzunehmen, dass sich Spuren dieser Methode noch heute finden lassen. Inwiefern dies wahrscheinlich ist, wird in der Zusammenfassung (Kapitel 6) thematisiert. (shrink)

How can work be a genuine good in life? I argue that this requires overcoming a problem akin to that studied by Marx scholars as the problem of work, freedom and necessity: how can work be something we genuinely want to do, given that its content is not up to us, but is determined by necessity? I argue that the answer involves valuing contributing to the good of others, typically as valuing active pro-sociality – that is, valuing actively doing something (...) good for others. This makes work better in one way, and may even make work something we are genuinely glad to have in our lives. Contemporary philosophical thinking about good work tends to focus on how work can be good for the person doing it, by providing, for example, self-realization or social relationships, while underappreciating the special importance of valuing social contribution. People will typically only really want work if they want a part of their lives to be about the good of others. This also means that work may be a part of the best life, something we should take into account when discussing work-related policies and the desirability of a ‘post-work’ future. (shrink)

In a recent article, I criticized Anthony L. Brueckner and John Martin Fischer’s influential argument—appealing to the rationality of our asymmetric attitudes towards past and future pleasures—against the Lucretian claim that death and prenatal non-existence are relevantly similar. Brueckner and Fischer have replied, however, that my critique involves an unjustified shift in temporal perspectives. In this paper, I respond to this charge and also argue that even if it were correct, it would fail to defend Brueckner and Fischer’s proposal against (...) my critique. (shrink)

Logic diagrams have been increasingly studied and applied for a few decades, not only in logic, but also in many other fields of science. The history of logic diagrams is an important subject, as many current systems and applications of logic diagrams are based on historical predecessors. While traditional histories of logic diagrams cite pioneers such as Leibniz, Euler, Venn, and Peirce, it is not widely known that Kant and the early Kantians in Germany and England played a crucial role (...) in popularising Euler(-type) diagrams. In this paper, the role of the Kantians in the late eighteenth and early nineteenth centuries will be analysed in more detail. It shows that diagrams (or intuition in general) were a highly contentious topic that depend on the philosophical attitude and went beyond logic to touch on issues of physics, metaphysics, linguistics and, above all, mathematics.

The paper examines Schopenhauer's logic lectures and the eristic dialectics of the manuscript remains in particular. The content of the logic lectures is briefly presented, then the characteristics are highlighted and finally Schopenhauer’s Euler diagrams are examined. The section on eristic dialectics summarizes the history of the text and its origin and reflects the content and order of the document.

The legacy of the Platonic dialogues may well lie, not in any classical idealist “doctrine of forms,” but in an inquisitive stance towards the puzzle behind any such doctrine—how thought can be about anything at all. This Platonic puzzle may, however, yield a different guise of idealism that is recognizably diagnostic: it aims to dispel our worry about thought’s objectivity as a confusion, engendered by a self-alienation of thought. These themes of diagnosis and idealism resurface in Wittgenstein, who in his (...) treatment of rules calls for an understanding of thought’s normativity from within. This is taken up by Cora Diamond, who urges philosophy to attend to thought’s real needs by exorcizing any desire for agreement with something other than itself. I argue that Wittgenstein and Diamond lead us back to Kant’s idealism, which identifies transcendental realism as the deep-seated prejudice at the root of the puzzle. (shrink)

To reconcile the standard possible worlds model of knowledge with the intuition that ordinary agents fall far short of logical omniscience, a Stalnakerian strategy appeals to two components. The first is the idea that mathematical and logical knowledge is at bottom metalinguistic knowledge. The second is the idea that non-ideal minds are often fragmented. In this paper, we investigate this Stalnakerian reconciliation strategy and argue, ultimately, that it fails. We are not the first to complain about the Stalnakerian strategy. But (...) in contrast to existing complaints, we want to cause trouble for the strategy directly on its home turf. That is, we will advance our objection while granting both the plausibility of the fragmentation component—save for an extreme version of it—and that of the metalinguistic component. Once our central objection to the Stalnakerian strategy is in place, we will show how it negatively affects Adam Elga and Augustín Rayo’s recent attempt to apply the Stalnakerian strategy in the context of Bayesian decision theory.

Contemporary conversations about religion and culture are framed by two reductive definitions of secularity. In one, multiple faiths and nonfaiths coexist free from a dominant belief in God. In the other, we deny the sacred altogether and exclude religion from rational thought and behavior. But is there a third way for those who wish to rediscover the sacred in a skeptical society? What kind of faith, if any, can be proclaimed after the ravages of the Holocaust and the many religion-based (...) terrors since? Richard Kearney explores these questions with a host of philosophers known for their inclusive, forward-thinking work on the intersection of secularism, politics, and religion. An interreligious dialogue that refuses to paper over religious difference, these conversations locate the sacred within secular society and affirm a positive role for religion in human reflection and action. Drawing on his own philosophical formulations, literary analysis, and personal interreligious experiences, Kearney develops through these engagements a basic gesture of hospitality for approaching the question of God. His work facilitates a fresh encounter with our best-known voices in continental philosophy and their views on issues of importance to all spiritually minded individuals and skeptics: how to reconcile God's goodness with human evil, how to believe in both God and natural science, how to talk about God without indulging in fundamentalist rhetoric, and how to balance God's sovereignty with God's love.

Suppose your evil sibling travels back in time, intending to lethally poison your grandfather during his infancy. Determined to save grandpa, you grab two antidotes and follow your sibling through the wormhole. Under normal circumstances, each antidote has a 50% chance of curing a poisoning. Upon finding young grandpa, poisoned, you administer the first antidote. Alas, it has no effect. The second antidote is your last hope. You administer it---and success: the paleness vanishes from grandpa's face, he is healed. As (...) you administered the first antidote, what was the chance that it would be effective? -/- This essay offers a systematic account of this case, and others like it. The central question is this: Given a certain time travel structure, what are the chances? In particular, I'll develop a theory about the connection between these chances and the chances in ordinary, time-travel-free contexts. Central to the account is a Markov condition involving the boundaries of spacetime regions. (shrink)

Eristic has been studied more and more intensively in recent years in philosophy, law, communication theory, logic, proof theory, and A.I. Nevertheless, the modern origins of eristic, which almost all current researchers see in the philosopher Arthur Schopenhauer, are considered to be a theory of the illegitimate use of logical and rhetorical devices. Thus, eristic seems to violate the norms of discourse ethics. In this paper, I argue that this interpretation of eristic is based on prejudices that contradict the original (...) intention of modern eristic. Eristic is not an art of being right or winning an argument, but an art of protecting oneself from the one who deliberately violates norms of discourse ethics to gain argumentative acceptance. For this reason, eristic must be seen as a discipline of Enlightenment philosophy and a correlate of discourse ethics. Especially in the age of alternative facts and post-factual politics, this makes eristic a valuable discipline. (shrink)

Pluralistic ignorance is a socio-psychological phenomenon that involves a systematic discrepancy between people’s private beliefs and public behavior in certain social contexts. Recently, pluralistic ignorance has gained increased attention in formal and social epistemology. But to get clear on what precisely a formal and social epistemological account of pluralistic ignorance should look like, we need answers to at least the following two questions: What exactly is the phenomenon of pluralistic ignorance? And can the phenomenon arise among perfectly rational agents? In (...) this paper, we propose answers to both these questions. First, we characterize different versions of pluralistic ignorance and define the version that we claim most adequately captures the examples cited as paradigmatic cases of pluralistic ignorance in the literature. In doing so, we will stress certain key epistemic and social interactive aspects of the phenomenon. Second, given our characterization of pluralistic ignorance, we argue that the phenomenon can indeed arise in groups of perfectly rational agents. This, in turn, ensures that the tools of formal epistemology can be fully utilized to reason about pluralistic ignorance. (shrink)

What happens when human beings fail to do as reason bids? This book is an attempt to address this age-old question within Kant’s mature practical philosophy, i.e. the practical philosophy that emerged with the watershed discovery of autonomy in the mid-1780s. As always, Kant is good for a surprise. There is, it is argued, not one answer but two: he advocates Socratic intellectualism in the realm of prudence whilst defending an anti-intellectualist or volitional account of immoral action. This ‘hybrid’ theory (...) of practical failure is more than a philosophical curiosity. There are ramifications for Kant’s theory of practical reason as a whole. In particular, the hybrid account emphasizes the divide between pure and empirical practical rationality to the extent that the latter, while containing practically relevant propositions, no longer counts as a branch of practical reason at all. Hypothetical and categorical imperatives exemplify two entirely distinct kinds of normativity. In fact, the dichotomy between pure and empirical determining grounds of the will goes hand in hand with many other dualisms and dichotomies that, whether we like them or not, continue to define Kant’s mature ethical thought.

The present article is an attempt to clarify the Kantian conception of duties to the self and to defend them against common objections. Kant’s thesis that all duty rests on duties to the self is shown to follow from the autonomy of the human will; and the allegation that they are impossible because the agent could always release himself from such a duty turns out to be question-begging. There is no attempt to prove that there are such duties, but they (...) are revealed to be an indispensable part of morality. Traditional attributes of moral commands, such as ‘categoricity’ or ‘overridingness’ make no sense in a one-sidedly other-regarding or social conception of morality. (shrink)

I raise two objections against Christian List and Peter Menzies' influential account of high-level causation. Improving upon some of Stephen Yablo's earlier work, I develop an alternative theory which evades both objections. The discussion calls into question List and Menzies' main contention, namely, that the exclusion principle, applied to difference-making, is false.

Kant scholarship often refers to transcendental idealism as a ‘theory.’ Kant’s project, however, is not easily reconciled with that term in its current use. This paper contends that his critique and idealism should be seen as a remedial response against our natural albeit confused prejudice of transcendental realism. Kant’s idealism articulates a ‘metametaphysical’ ethos that is supposed to provide a new grounding of metaphysics by proceeding ‘from the human standpoint:’ it aims to dispel the temptation of transcendental realism in favor (...) of a resolute inhabitation of, and contentment with, our own humanity. This project comes under pressure in post-Kantianism: Fichte is among the first to voice the worry that Kant’s critique is well-intentioned, but not well-executed. His concern is that, while it ‘bring[s] man into harmony with himself,’ this mere contentment with our own humanity will not suffice to achieve the scientificity that, by Kant’s own lights, is the mark of any promising metaphysics. Fichte’s charge is that Kant’s idealism, in its very confinement to the brute facts of the human condition, surrenders itself to unacceptable contingency or ‘facticity.’ The paper explores Kant’s idealist project of grounding metaphysics, Fichte’s facticity charge against it, and whether Kantian idealism can withstand it.

In a possible world framework, an agent can be said to know a proposition just in case the proposition is true at all worlds that are epistemically possible for the agent. Roughly, a world is epistemically possible for an agent just in case the world is not ruled out by anything the agent knows. If a proposition is true at some epistemically possible world for an agent, the proposition is epistemically possible for the agent. If a proposition is true at (...) all epistemically possible worlds for an agent, the proposition is epistemically necessary for the agent, and as such, the agent knows the proposition. -/- This framework presupposes an underlying space of worlds that we can call epistemic space. Traditionally, worlds in epistemic space are identified with possible worlds, where possible worlds are the kinds of entities that at least verify all logical truths. If so, given that epistemic space consists solely of possible worlds, it follows that any world that may remain epistemically possible for an agent verifies all logical truths. As a result, all logical truths are epistemically necessary for any agent, and the corresponding framework only allows us to model logically omniscient agents. This is a well-known consequence of the standard possible world framework, and it is generally taken to imply that the framework cannot be used to model non-ideal agents that fall short of logical omniscience. -/- A familiar attempt to model non-ideal agents within a broadly world involving framework centers around the use of impossible worlds where the truths of logic can be false. As we shall see, if we admit impossible worlds where “anything goes” in epistemic space, it is easy to avoid logical omniscience. If any logical falsehood is true at some impossible world, then any logical falsehood may remain epistemically possible for some agent. As a result, we can use an impossible world involving framework to model extremely non-ideal agents that do not know any logical truths. -/- A much harder, and considerably less investigated challenge is to ensure that the resulting epistemic space can also be used to model moderately ideal agents that are not logically omniscient but nevertheless logically competent. Intuitively, while such agents may fail to rule out impossible worlds that verify complex logical falsehoods, they are nevertheless able to rule out impossible worlds that verify obvious logical falsehoods. To model such agents, we need a construction of a non-trivial epistemic space that partly consists of impossible worlds where not "anything goes". This involves imposing substantive constraints on impossible worlds to eliminate from epistemic space, say, trivially impossible worlds that verify obvious logical falsehoods. -/- The central aim of this dissertation is to investigate the nature of such non-trivially impossible worlds and the corresponding epistemic spaces. To flag my conclusions, I argue that successful constructions of epistemic spaces that can safely navigate between the Charybdis of logical omniscience and the Scylla of of “anything goes” are hard, if not impossible to find.

The mechanistic view of computation contends that computational explanations are mechanistic explanations. Mechanists, however, disagree about the precise role that the environment – or the so-called “contextual level” – plays for computational explanations. We advance here two claims: Contextual factors essentially determine the computational identity of a computing system ; this means that specifying the “intrinsic” mechanism is not sufficient to fix the computational identity of the system. It is not necessary to specify the causal-mechanistic interaction between the system and (...) its context in order to offer a complete and adequate computational explanation. While the first claim has been discussed before, the second has been practically ignored. After supporting these claims, we discuss the implications of our contextualist view for the mechanistic view of computational explanation. Our aim is to show that some versions of the mechanistic view are consistent with the contextualist view, whilst others are not. (shrink)

This paper argues in favor of a hybrid conception of identity. A common conception of identity in datafied society is a split between a digital self and a real self, which has resulted in concepts such as the data double, algorithmic identity, and data shadows. These data-identity metaphors have played a significant role in the conception of informational privacy as control over information—the control of or restricted access to your digital identity. Through analyses of various data-identity metaphors as well as (...) philosophical accounts of identity, we argue in favor of a hybrid conception of identity that emphasizes the relations between the ‘real’ and the ‘digital’. A hybrid conception of identity—where the digital is an aspect on par with social relations, self-understanding, and values—ultimately calls for an understanding of privacy as the right to influence one’s own identity.

The way we use terminology matters. There are words, ordinary and philosophical, that we should do without because they are ill-defined, ambiguous or confused. If we use them we will at best be saying little. At worst, they will make us ask the wrong questions and leave the right ones unasked. In this paper, I argue that ‘deontology’ is such a word. It is defined negatively as non-teleological or non-consequentialist, and therefore does not designate a distinct class of moral theories, (...) let alone a single one. Moreover, the question whether Kantian ethics is ‘deontological’ is likely to obscure what is distinctive and interesting about it. The word ‘deontology’ should be banished from the classroom. It may be best to abandon it altogether. (shrink)

Is Kant’s ethical theory too demanding? Do its commands ask too much of us, either by calling for self-sacrifice on particular occasions, or by pervading our lives to the extent that there is no room for permissible action? In this article, I argue that Kant’s ethics is very demanding, but not excessively so. The notion of ‘latitude’ does not help. But we need to bear in mind that moral laws are self-imposed and cannot be externally enforced; that ‘right action’ is (...) not a category of Kantian ethics – there is a more and a less, and lack of perfection does not entail vice; and that only practice makes perfect, i.e. how much virtue can realistically be expected can vary from agent to agent. The principle that ‘ought’ is limited by ‘can’ is firmly entrenched in Kant’s ethical thought. (shrink)

Logic diagrams have seen a resurgence in their application in a range of fields, including logic, biology, media science, computer science and philosophy. Consequently, understanding the history and philosophy of these diagrams has become crucial. As many current diagrammatic systems in logic are based on ideas that originated in the 18th and 19th centuries, it is important to consider what motivated the use of logic diagrams in the past and whether these reasons are still valid today. This paper proposes that (...) transcendental philosophy was a key inspiration for the development of logic diagrams and that such diagrams can be employed in transcendental arguments, even after the linguistic turn.

I denne artikel argumenteres der for, at døden i Phaidon primært skal forstås metaforisk, som sjælens adskillelse fra kroppen i den rene tænkning. Artiklens hovedtese er, at de fire argumenter for sjælens udødelighed, der findes i dialogen, skal læses som en fremadskridende afklaring af, hvilken væremåde sjælen har, når den isolerer sig fra kroppen, snarere end at læses bogstaveligt som beviser for, at sjælen er udødelig. Tillige argumenteres der for, at den såkaldt anden sejlads – Sokrates’ beskrivelse af, hvorledes han (...) for at forstå virkeligheden søgte tilflugt i argumenter og ideer snarere end i sanserne – skal forstås som et forsvar for en bestemt opfattelse af menneskelig frihed. Når Sokrates indfører ideerne som årsager i løbet af Phaidon, skal dette først og fremmest ses som en forklaring på, hvordan den rene tænkning kan erkende virkeligheden og derigennem kontrollere vores umiddelbare tilbøjeligheder. Det er mulighedsbetingelsen for menneskelig frihed som Platons Sokrates forstår den. Frihed skal da primært forstås som mulighed, nemlig mulighed til at handle i overensstemmelse med det, den fornuftsbestemte indsigt tilsiger en, at man skal gøre, uden hensyntagen til umiddelbare, kropsligt bestemte tilbøjeligheder, herunder tilbøjeligheden til selvopretholdelse for enhver pris. Den foreslåede læsning peger dermed på en politisk dimension af Phaidon, der ofte overses som følge af, at argumenterne for sjælens udødelighed tages for bogstaveligt. (shrink)

This article examines the evolution of the concept of existence in modern visual representation and reasoning, highlighting important milestones. In the late eighteenth century, during the so-called golden age of visual reasoning, nominalism reigned supreme and there was limited scope for existential import or individuals in logic diagrams. By the late nineteenth century, a form of realism had taken hold, whose existential commitments continue to dominate many areas in logic and visual reasoning to this day. Physical, metaphysical, epistemological, and linguistic (...) positions underlie both nominalist and realist views. Since the paradigmatic works on visual reasoning in the 1990s, formal diagram systems have been developed that revive either the nominalist or realist perspectives. Unlike in the nineteenth century, these are not motivated by philosophical views. Nevertheless, they may still have an impact on many areas of philosophy and science outside logic. (shrink)

If ethics of care deals with the nature of relationships, attentiveness, and understanding particular others, narrativity ought to play a central part. Sometimes, caring simply amounts to working with narratives. In the article I claim that narrativity can even be said to be native to an ethics of care. Through an example, I demonstrate how a narrative ethics of care can discern and grasp some moral problems better than the standard theoretical outlooks.

Our beliefs and opinions are shaped by others, making our social networks crucial in determining what we believe to be true. Sometimes this is for the good because our peers help us form a more accurate opinion. Sometimes it is for the worse because we are led astray. In this context, we address via agent-based computer simulations the extent to which patterns of connectivity within our social networks affect the likelihood that initially undecided agents in a network converge on a (...) true opinion following group deliberation. The model incorporates a fine-grained and realistic representation of belief and trust, and it allows agents to consult outside information sources. We study a wide range of network structures and provide a detailed statistical analysis concerning the exact contribution of various network metrics to collective competence. Our results highlight and explain the collective risks involved in an overly networked or partitioned society. Specifically, we find that 96% of the variation in collective competence across networks can be attributed to differences in amount of connectivity and clustering, which are negatively correlated with collective competence. A study of bandwagon or “group think” effects indicates that both connectivity and clustering increase the probability that the network, wholly or partly, locks into a false opinion. Our work is interestingly related to Gerhard Schurz’s work on meta-induction and can be seen as broadly addressing a practical limitation of his approach. (shrink)

Reism or concretism are the labels for a position in ontology and semantics that is represented by various philosophers. As Kazimierz Ajdukiewicz and Jan Woleński have shown, there are two dimensions with which the abstract expression of reism can be made concrete: The ontological dimension of reism says that only things exist; the semantic dimension of reism says that all concepts must be reduced to concrete terms in order to be meaningful. In this paper we argue for the following two (...) theses: (1) Arthur Schopenhauer has advocated a reistic philosophy of language which says that all concepts must ultimately be based on concrete intuition in order to be meaningful. (2) In his semantics, Schopenhauer developed a theory of logic diagrams that can be interpreted by modern means in order to concretize the abstract position of reism. Thus we are not only enhancing Jan Woleński’s list of well-known reists, but we are also adding a diagrammatic dimension to concretism, represented by Schopenhauer. (shrink)

In a crucial passage in the Republic found within a discussion of women’s role in the ideal polis, division of eidē is identified as necessary for dialectic. A careful consideration of the way division is described in this passage reveals that it resembles the procedure of division described in the Phaedrus and the Sophist and that this procedure, when carried out correctly, is central to dialectic according to the Republic and helps set dialectic apart from eristic. Consideration of additional passages (...) in the Republic indicates that division may be employed on different kinds of entities, such as virtues and types of human natures; for according to the argument of the Republic, the correct use of division for the purpose of distinguishing types of human natures or virtues, entities that to the untrained eye may look alike but are distinct by nature, is required for achieving the knowledge philosophers and philosopher-rulers need. In fact, correctly performed divisions help the dialectician to bring into focus a subject matter under consideration in a kind of double-vision that reveals that matter as a concrete phenomenon that exhibits participation in different eidê when it is considered from different points of view.

In light of the problem of logical omniscience, some scholars have argued that belief is question-sensitive: agents don't simply believe propositions but rather believe answers to questions. Hoek (2022) has recently developed a version of this approach on which a belief state is a "web" of questions and answers. Here, we present several challenges to Hoek's question-sensitive account of belief. First, Hoek's account is prone to very similar logical omniscience problems as those he claims to address. Second, the link between (...) belief and action he proposes is too rigid. We close by sketching a generalization of the account that can meet these challenges. (shrink)

The Parmenides poses the question for what entities there are Forms, and the criticism of Forms it contains is commonly supposed to document an ontological reorientation in Plato. According to this reading, Forms no longer express the excellence of a given entity and a Socratic, ethical perspective on life, but come to resemble concepts, or what concepts designate, and are meant to explain nature as a whole. Plato’s conception of dialectic, it is further suggested, consequently changes into a value-neutral method (...) directed at tracing the interrelation of such Forms, an outlook supposedly documented in certain passages on method from the Sophist and the Statesman as well. -/- The article urges that this reading is untenable. For in the Parmenides the question for what entities one should posit Forms is left open, and the passages on method from the Sophist and Statesman neither encourage a non-normative ontology nor a value-neutral method of inquiry. What the three dialogues encourage us to do is rather to set common opinions about the relative worth and value of things aside when conducting ontological inquiries; and this attitude, the article concludes, demonstrates a close kinship, rather than a significant difference, between Plato’s Socrates and his Eleatic philosophers.

Kant lectured on moral philosophy fairly regularly over the course of his long, 40-year teaching career. Bearing a variety of different titles such as “Practical Philosophy”, “Ethics”, and “Universal Practical Philosophy and Ethics”, we have evidence that Kant offered a course on moral philosophy in at least 28 different semesters (of these we can prove that 19 actually took place, 9 others were advertised and there is good reason to think that they took place - see Arnoldt 1909). This means (...) that Kant offered a course on ethics in approximately one third of every semester he taught. The student notes from these lectures have proved invaluable resources for gaining insight into Kant’s intellectual development, his opinion on issues not covered extensively in the published works, and his character as a university instructor, among many others things. From his lectures on ethics, 23 distinct sets of notes are thought to have existed at any one point in time, but many of these have since been lost or destroyed (see Naragon 2006). Only 14 sets of notes still exist, either as an original, a copy, a published version of a subsequently lost manuscript, or just a collection of fragments (ibid.). But each of these are not unique, distinct sets of notes. For example: of the 23 sets of known notes, 13 of them belong to the same group in the sense that they are thought to all be copies of one original set. In the end, we possess only five distinct sets of notes from Kant’s lectures on ethics, stemming from various periods of his life: Herder (1760s), Kaehler/Collins (1770s), Powalski (1782/3), Mrongovius (1784/5), and Vigilantius (1790s). In what follows, each of these sets of notes will be given their own brief discussion. (shrink)

Beginning with a research review, the present paper shows that Hans Slugaʼs and esp. Robert Brandomʼs thesis, according to which Frege has adopted the context-principle and the priority of propositional from Kant, can solve problems in current Frege scholarship, on the one hand, but is itself fraught with further problems, on the other hand. In contrast, this paper maintains that the context-principle and the priority of the propositional are implicitly present in Fregeʼs Begriffsschrift since both have not been taken over (...) from Kant, but rather from neo-Aristotelianism: The context-principle and the priority of the propositional were first drawn up in 1834 by O. F. Gruppe. As a consequence, A. F. Trendelenburg has published a re-arranged edition of Aristotleʼs Organon in 1836 which became one of the most influential schoolbooks on logic in the 19th century and of which Frege ought to have been aware. In the beginning of this schoolbook, using the original ancient Greek sentences of Aristotle, the priority of the propositional (De int. I 1) is deduced from the context-principle (De anima III 6).

In 1993, Richard Hare argued that, contrary to received opinion, Kant could have been a utilitarian. In this article, I argue that Hare was wrong. Kant's theory would not have been utilitarian or consequentialist even if his practical recommendations coincided with utilitarian commands: Kant's theory of value is essentially anti-utilitarian; there is no place for rational contradiction as the source of moral imperatives in utilitarianism; Kant would reject the move to separate levels of moral thinking: first-order moral judgement makes use (...) of the principle of morality; and, relatedly, he would resist the common utilitarian distinction between actions and their motives because any correct description of an action must refer to motivation. The article concludes with the thought that any consequentialist theory based on pre-given ends (teleology) lacks the philosophical resources to distinguish between willing something as a means and as an end, leaving means only, and destroying transparency.

Schopenhauers Auseinandersetzungen mit dem Christentum und der Mystik werden im Folgenden unter drei Aspekten betrachtet: Methodologie und Definitionen, Doxographie der Dogmatik, Mystologie und Hagiologie. In ersten Abschnitt werden Schopenhauers Herangehensweisen und Meinungen im Umgang mit dem Christentum beschrieben. Im zweiten Abschnitt werden einschlägige Belegstellen aus Schopenhauers Werk zu christlich-dogmatischen Themen zusammengestellt und systematisiert. Im dritten Abschnitt wird nach der Funktion und Bedeutung der christlichen Mystiker und Heiligen für Schopenhauers Leben und Werk gefragt.

Charles Darwin gilt allgemein als der ›Erfinder‹ der Evolutionstheorie. Dennoch sehen viele Wissenschaftshistoriker bereits in der Antike Anfänge und einzelne Vorwegnahmen der heutigen Entwicklungsbiologie. Die Tatsache, dass der im Titel genannte Ausdruck ›Evolutionstheorie‹ in Anführungszeichen gesetzt wurde, ist somit kein Hinweis auf die Vorzeitigkeit Schopenhauers zu Darwin, sondern betrifft die kritische Frage, ob man Schopenhauer überhaupt in diese Geschichte der Evolutionstheorie mit aufnehmen sollte oder nicht.
