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.

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)

According to the “deprivation approach,” a person’s death is bad for her to the extent that it deprives her of goods. This approach faces the Lucretian problem that prenatal non-existence deprives us of goods just as much as death does, but does not seem bad at all. The two most prominent responses to this challenge—one of which is provided by Frederik Kaufman (inspired by Thomas Nagel) and the other by Anthony Brueckner and John Martin Fischer—claim that prenatal non-existence is relevantly (...) different from death. This paper criticizes these responses. (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.

A prominent objection to the counterfactual comparative account of harm is that it classifies as harmful some events that are, intuitively, mere failures to benefit. In an attempt to solve this problem, Duncan Purves has recently proposed a novel version of the counterfactual comparative account, which relies on a distinction between making upshots happen and allowing upshots to happen. In this response, we argue that Purves’s account is unsuccessful. It fails in cases where an action makes the subject occupy a (...) high well-being level though one of the available alternatives would have made it even higher. In fact, it fails even in some cases where each of the available alternatives to the action that was actually performed would have made the subject’s well-being level lower. (shrink)

The traditional Lewis–Stalnaker semantics treats all counterfactuals with an impossible antecedent as trivially or vacuously true. Many have regarded this as a serious defect of the semantics. For intuitively, it seems, counterfactuals with impossible antecedents—counterpossibles—can be non-trivially true and non-trivially false. Whereas the counterpossible "If Hobbes had squared the circle, then the mathematical community at the time would have been surprised" seems true, "If Hobbes had squared the circle, then sick children in the mountains of Afghanistan at the time would (...) have been thrilled" seems false. Many have proposed to extend the Lewis–Stalnaker semantics with impossible worlds to make room for a non-trivial or non-vacuous treatment of counterpossibles. Roughly, on the extended Lewis–Stalnaker semantics, we evaluate a counterfactual of the form "If A had been true, then C would have been true" by going to closest world—whether possible or impossible—in which A is true and check whether C is also true in that world. If the answer is "yes", the counterfactual is true; otherwise it is false. Since there are impossible worlds in which the mathematically impossible happens, there are impossible worlds in which Hobbes manages to square the circle. And intuitively, in the closest such impossible worlds, sick children in the mountains of Afghanistan are not thrilled—they remain sick and unmoved by the mathematical developments in Europe. If so, the counterpossible "If Hobbes had squared the circle, then sick children in the mountains of Afghanistan at the time would have been thrilled" comes out false, as desired. In this paper, I will critically investigate the extended Lewis–Stalnaker semantics for counterpossibles. I will argue that the standard version of the extended semantics, in which impossible worlds correspond to maximal, logically inconsistent entities, fails to give the correct semantic verdicts for many counterpossibles. In light of the negative arguments, I will then outline a new version of the extended Lewis–Stalnaker semantics that can avoid these problems. (shrink)

According to epistemic two-dimensionalism, or simply two-dimensionalism, linguistic expressions are associated with two intensions, one of which represents an expression’s a priori implications. The author investigates the prospects of conceptual analysis on the basis of a two-dimensionalist theory of meaning. He discusses a number of arguments for and against two-dimensional semantics and argues that properly construed, two-dimensionalism provides a potent and plausible account of meaning. Against the background of this account, the author then goes on to assess the value of (...) conceptual analysis in philosophical practice, outlining its goals, its promises, but also its limitations.

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)

Das Buch behandelt Kants Versuch, innerhalb seiner Ethik Sittengesetz, Naturgesetz und Freiheit im moralischen Handeln in Einklang zu bringen. Im ersten Teil stehen die Begriffe der Freiheit und des Willens bei Kant im Mittelpunkt. Der zweite Teil untersucht detailliert die Kernpunkte der kantischen Ethik: den (letztlich gescheiterten) Versuch, Freiheit und Naturkausalit t auszus hnen, und die Theorie des Handelns nach Moralgesetzen, deren Wahl den freien Willen als eigentliches Moment ausmacht. Am Ende steht die Einsicht in ein hoch entwickeltes, differenziertes gedankliches (...) System, das unserer Alltagsauffassung von moralischer Verantwortung erstaunlich nahe kommt. (shrink)

Derek Parfit famously defends a number of surprising views about "fission." One is that, in such a scenario, it is indeterminate whether I have survived or not. Another is that the fission case shows that it does not matter, in itself, whether I survive or not. Most critics of the first view contend that fission makes me cease to exist. Most opponents of the second view contend that fission does not preserve everything that matters in ordinary survival. In this paper (...) I shall provide a critique that does not rely on either of these contentions. There are other, interrelated reasons to reject Parfit's defense of the two theses. In particular, the availability of the following view creates trouble for Parfit: I determinately survive fission, but it is indeterminate which fission product I am. (shrink)

This paper analyses a hitherto unknown technique of using logic diagrams to create argument maps in eristic dialectics. The method was invented in the 1810s and -20s by Arthur Schopenhauer, who is considered the originator of modern eristic. This technique of Schopenhauer could be interesting for several branches of research in the field of argumentation: Firstly, for the field of argument mapping, since here a hitherto unknown diagrammatic technique is shown in order to visualise possible situations of arguments in a (...) dialogical controversy. Secondly, the art of controversy or eristic, since the diagrams do not analyse the truth of judgements and the validity of inferences, but the persuasiveness of arguments in a dialogue. (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)

Pauline Kleingeld’s “Contradiction and Kant’s Formula of Universal Law”, published in this journal in 2017, presents a powerful challenge to what has become the standard reconstruction of the categorical imperative. In this response to Kleingeld, I argue that she is right to emphasise the ‘simultaneity requirement’ - that we must be able to will a proposed maxim and ‘simulataneously’, ‘also’ or ‘at the same time’ the maxim in its universalised form - but I deny that this removes the categorical imperative (...) test from the world of universalisation because the agent must be understood as part of that world. There are two distinct types of conflict: a contradiction that results from non-universalisability and Kleingeld’s ‘volitional’ conflict, located within the will of the immoral agent. The standard ‘practical’ reconstruction of the categorical imperative remains largely intact. (shrink)

According to the standard version of the counterfactual comparative account of harm, an event is overall harmful for an individual if and only if she would have been on balance better off if it had not occurred. This view faces the “preemption problem.” In the recent literature, there are various ingenious attempts to deal with this problem, some of which involve slight additions to, or modifications of, the counterfactual comparative account. We argue, however, that none of these attempts work, and (...) that the preemption problem continues to haunt the counterfactual comparative account. (shrink)

Normative discussions about modern health care often revolve around principles stating what must not be done or how to ration scarce resources in the name of justice. These are important discussions. However, in order to have an impact on clinical roles, ethical reflection must be able to describe and address the complexities and challenges of modern nursing and doctoring, and maybe even the patient role. A multi-principled approach, such as the one suggested by Beauchamp and Childress, can obviously address almost (...) any such issue, but a great deal of translation is often required in order to address role-related issues. I shall here argue that an ethics of caring is better suited to grasping the big picture when the question is how to create value-informed clinical roles in an era of rapid development. (shrink)

To believe that logic has no history might at first seem peculiar today. But since the early 20th century, this position has been repeatedly conflated with logical monism of Kantian provenance. This logical monism asserts that only one logic is authoritative, thereby rendering all other research in the field marginal and negating the possibility of acknowledging a history of logic. In this paper, I will show how this and many related issues have developed, and that they are founded on only (...) one prominent statement by Kant. I will argue, however, that this statement takes on a very different meaning in a broader context of the history and philosophy of science, and that Kant and his supporters never advocated the logical monism that they are still said to hold today.

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)

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)

It has recently been argued that a sensitivity theory of knowledge cannot account for intuitively appealing instances of higher-order knowledge. In this paper, we argue that it can once careful attention is paid to the methods or processes by which we typically form higher-order beliefs. We base our argument on what we take to be a well-motivated and commonsensical view on how higher-order knowledge is typically acquired, and we show how higher-order knowledge is possible in a sensitivity theory once this (...) view is adopted.

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.

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.

A pure time preference is a preference for something to occur at one point in time rather than another, merely because of when it occurs in time. Such preferences are widely regarded as paradigm examples of irrational preferences. However, Rosemary Lowry and Martin Peterson have recently argued that, for instance, a pure time preference to go to the opera tonight rather than next month may be rationally permissible, even if the amounts of intrinsic value realized in both cases are identical. (...) In this reply, we argue that Lowry and Peterson's argument is unsuccessful. (shrink)

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.

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)

Since Barry Stroud's classic paper in 1968, the general discussion on transcendental arguments tends to focus on examples from theoretical philosophy. It also tends to be pessimistic, or at least extremely reluctant, about the potential of this kind of arguments. Nevertheless, transcendental reasoning continues to play a prominent role in some recent approaches to moral philosophy. Moreover, some authors argue that transcendental arguments may be more promising in moral philosophy than they are in theoretical contexts. Against this background, the current (...) volume focuses on transcendental arguments in practical philosophy. Experts from different countries and branches of philosophy share their views about whether there are actually differences between "theoretical" and "practical" uses of transcendental arguments. They examine and compare different versions of transcendental arguments in moral philosophy, explain their structure, and assess their respective problems and promises. This book offers all those interested in ethics, meta-ethics, or epistemology a more comprehensive understanding of transcendental arguments. It also provides them with new insights into uses of transcendental reasoning in moral philosophy. (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)

According to the modal account of propositional apriority, a proposition is a priori if it is possible to know it with a priori justification. Assuming that modal truths are necessarily true and that there are contingent a priori truths, this account has the undesirable consequence that a proposition can be a priori in a world in which it is false. Epistemic two-dimensionalism faces the same problem, since on its standard interpretation, it also entails that a priori propositions are necessarily a (...) priori. In response to this problem, Chalmers and Rabern propose an alternative conception of propositional apriority as well as two-dimensional truth-conditions for apriority statements. Their proposal is also supposed to avoid another problem for the modal account, namely that it entails the existence of false instances of ‘φ iff actually φ’. I discuss Chalmers and Rabern’s account and point out a number of problems with it. I then develop my own account of propositional apriority that solves the problems in question, that can be accepted by friends and foes of two-dimensionalism alike, and that is also neutral with respect to the question of how one construes the objects of propositional apriority.

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.

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)

National Artificial Intelligence (AI) strategies articulate imaginaries of the integration of AI into society and envision the governing of AI research, development and applications accordingly. To integrate these central aspects of national AI strategies under one coherent perspective, this paper presented an analysis of Germany’s strategy ‘AI made in Germany’ through the conceptual lens of ordoliberal political rationality. The first part of the paper analyses how the guiding vision of a human-centric AI not only adheres to ethical and legal principles (...) consistent with Germany’s liberal democratic constitutional system but also addresses the risks and promises inherent to the ordoliberal problematization of freedom. Second, it is scrutinized how the strategy cultivates the fear of not achieving technological sovereignty in the AI sector. Thereby, it frames the global AI race as a race of competing (national) approaches to governing AI and articulates an ordoliberal approach to governing AI (the ‘third way’), according to which government has to operate between the twin dangers of governing too much and not governing enough. Third, the paper analyses how this ordoliberal proportionality of governing structures Germany’s Science Technology & Innovation Policy. It is shown that the corresponding risk-based approach of regulating AI constitutes a security apparatus as it produces an assessment of fears: weighting the fear of the failure to innovate with the fear of the ramifications of innovation. Finally, two lines of critical engagement based on this analysis are conducted. (shrink)

This article defends three claims. First, that collection and division in the Phaedrus are described as procedures that underlie human speaking and thinking in general, as well as philosophical inquiry, and are not identified with either. Second, that what sets the dialectical use of these procedures apart from their ordinary use are philosophical suppositions independent of the procedures of collection and division themselves; for that reason, collection and division cannot be identified with dialectic as such. Third, that the second part (...) of the Phaedrus is concerned with the broader question how noble or beautiful speaking, in general, may be said to depend on dialectic as much as it is concerned with the question how rhetoric, as a kind of expertise, is related to dialectic.

According to luck egalitarianism, it is not unfair when people are disadvantaged by choices they are responsible for. This implies that those who are disadvantaged by choices that prevent disadvantage to others are not eligible for compensation. This is counterintuitive. We argue that the problem such cases pose for luck egalitarianism reveals an important distinction between responsibility for creating disadvantage and responsibility for distributing disadvantage which has hitherto been overlooked. We develop and defend a version of luck egalitarianism which only (...) holds people responsible for creating disadvantage. This revision enables luck egalitarianism to offer compensation to those who are disadvantaged by preventing disadvantage to others, like dependent caretakers, without compromising the responsibility–sensitivity at the heart of luck egalitarianism.

In this paper, I identify and discuss the following feature of our judgments about hypothetical scenarios concerning the identity of persons: with respect to the vast majority of scenarios, both members of a pair of logically complementary propositions about personal identity are conceivable. I consider a number of explanations of this feature that draw on the metaphysics and the epistemology of personal identity, none of which prove to be satisfactory. I then argue that in order to give an adequate explanation, (...) one needs to recognize an important characteristic of our concept of personal identity: it is such that if there are mental substances (or the like), they constitute personal identity. At the same time, there can still be persons if there are no such substances. Since this finding casts doubts on the way that thought experiments about personal identity are usually set up, I end by outlining its potential consequences for the debate over the identity of persons.

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

There has recently been a revived interest in temporal justice among political philosophers. For example, lone mothers have, on average, 30 h less free time per week than people in couples without children. Recent work has focussed on free time as a distinct distributive good, but this paper argues that it would be a mistake for a theory of temporal justice to focus only on shares of free time. First, I argue that the concept of free time does not succeed (...) in tracking discretionary control over time. All of time is a resource, and the particular moral relevance of free time must be established otherwise. Second, hours of time differ in use value, and we cannot fully track our concerns about the allocation of time, whether free or necessary, without taking this into account. We care about free time but also about ‘quality time’. To explain this observation, I develop an account of the value of time as a resource. The value of time periods differs with the prospects for which a time period can be used, that is, what we can do and be with it. What we are allocating when we are allocating time is not just hours; it is hours of time with a certain value. Finally, I argue that a concern for the value of time is compatible with a resourcist theory of temporal justice. (shrink)

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)

Future-directed intentions, it is widely held, involve behavioral dispositions. But of what kind? Suppose you now intend to Φ at future time t. Are you thereby now disposed to Φ at t no matter what? If so, your intention disposes you to Φ even if around t you will come to believe that Φ-ing would be crazy. And would not that be a crazy intention to have? – Like considerations have led Luca Ferrero and others to believe that only intentions (...) with strong internal conditions are capable of rationality. This paper explores in how far a broadly dispositional view of intention supports their claims. Its first point will come as a surprise: Intentions indeed involve dispositions toward follies in plenty. Natural objections against this bizarre-sounding claim are shown to fail, and standard counterfactual analyses of disposition locutions are shown to underpin it further. However, since the dispositions at issue are pro tanto dispositions, the consequences are not as odd as might be expected: When hedged by reasonable habits to reconsider one’s intentions, dispositions toward follies do not entail any actual crazy behavior. On balance, unconditional intention is therefore found rational after all. Dispositions toward crazy actions need not be crazy dispositions. (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)

Due to increasing consumer skepticism towards promotional messages, companies are looking for new ways to communicate with their target audiences in a less obtrusive way than traditional advertising. Sponsored content disseminated on the online portals of newspapers (i. e., online advertorials) is regarded as a promising way to promote products and brands. Regulations require communicators to inform consumers about the commercial nature of this ‘masked’ persuasion attempt by including an explicit sponsorship disclosure (i. e., a ‘Sponsored’ label). This study demonstrates (...) that such an explicit advertising cue may not be enough to alert recipients. Furthermore, this study investigates the effects of promotional messages by means of a 2 (no disclosure vs. disclosure) x 2 (no forewarning vs. forewarning) experiment. Results show that both (i) foregoing instructions aimed at activating consumers’ persuasion knowledge (i. e., an additional forewarning message) and (ii) recipients’ prior media literacy can foster the effect of sponsorship disclosures in triggering situational distrust towards brand-related content, and in turn, increasing consumers’ reactance.

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)

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.
