Sentences with disjunction in the scope of a universal quantifier, Every A is P or Q, tend to give rise to distributive inferences that each of the disjuncts holds of at least one individual in the domain of the quantifier, Some A is P & Some A is Q. These inferences are standardly derived as an entailment of the meaning of the sentence together with the scalar implicature that it is not the case that either disjunct holds of every individual (...) in the domain of the quantifier, \Every A is P &\Every A is Q. As we show, this derivation faces a challenge in that distributive inferences may obtain in the absence of plain negated inferences. We address this challenge by showing that on particular assumptions about alternatives, a derivation of distributive inferences as scalar implicatures can be maintained without in fact necessitating plain negated inferences. These assumptions accord naturally with the grammatical approach to scalar implicatures. We also present experimental data that suggest that plain negated inferences are not only unnecessary for deriving distributive inferences, but might in fact be unavailable. (shrink)

The idea that particular legal institutions are artifacts is not new. However, the idea that the “law” or “legal system” is itself an artifact has seldom been directly put forward, due perhaps to the ambiguities surrounding philosophical inquiries into law. Nevertheless, such an idea has recently been invoked more often, though not always developed in detail in terms of what the characterization of the “law” or “legal system” as an artifact entails ontologically, and what consequences, if any, this has for (...) philosophical accounts of law. As a result, the primary aim of this paper is to attempt an inquiry into what the claim that “law” by its nature or character is an artifact entails, and what an artifact theory of law might look like.

ABSTRACT This essay examines the exhibition of dinosaurs at the American Museum of Natural History during the first two decades of the twentieth century. Dinosaurs provide an especially illuminating lens through which to view the history of museum display practices for two reasons: they made for remarkably spectacular exhibits; and they rested on contested theories about the anatomy, life history, and behavior of long-extinct animals to which curators had no direct observational access. The American Museum sought to capitalize on the (...) popularity of dinosaurs while mitigating the risks of mounting an overtly speculative display by fashioning them into a kind of mixed-media installation made of several elements, including fossilized bone, shellac, iron, and plaster. The resulting sculptures provided visitors with a vivid and lifelike imaginative experience. At the same time, curators, who were anxious to downplay the speculative nature of mounted dinosaurs, drew systematic attention to the material connection that tied individual pieces of fossilized bone to the actual past. Freestanding dinosaurs can therefore be read to have functioned as iconic sculptures that self-consciously advertised their indexical content. (shrink)

Climate change can be interpreted as a unique case of historical injustice involving issues of both intergenerational and global justice. We split the issue into two separate questions. First, how should emission rights be distributed? Second, who should come up for the costs of coping with climate change? We regard the first question as being an issue of pure distributive justice and argue on prioritarian grounds that the developing world should receive higher per capita emission rights than the developed world. (...) This is justified by the fact that the latter already owns a larger share of benefits associated with emission generating activities because of its past record of industrialisation. The second question appears to be an issue of compensatory justice. After defining what we mean by compensation, we show that different kinds of compensatory principles run into problems when used to justify payments by historical emitters of the North to people suffering from climate change in the South. As an alternative, we propose to view payments from wealthy countries for adaptation to climate change in vulnerable countries rather as a measure based on concerns of global distributive justice.

Using the technique of prepared questions, Conversations with Lukacs is a brilliant gathering of thoughts and insights covering topics as ontology, the techniques of manipulative societies, the pitfalls of combating Stalinism with Stalinist methods, and the problems of intellectuals in advanced capitalist societies. Above all, there is the restatement of Lukacs unshaken conviction that the working class, with all the changes that have occurred in its way of life and composition, is still the historical carrier of social transformation. Lukacs's interlocutors (...) in these four conversations are Hans Heinz Holz, Leo Kofler, and Wolfgang Abendroth. Each of them engages Lukacs in separate dialogues, on being and consciousness (Holz), on society and the individual (Kofler), and on the elements of scientific politics (Abendroth). Lukacs, Abendroth, and Holz work toward a "Provisional Summary" in the last conversation. The interlocutors and the editor write that "These conversations show very clearly the basis of abstraction in the experiences of everyday life.... This gives these conversations with Lukacs a more than anecdotal value; for the unmediated way in which thought is produced in conversation corresponds exactly to that primary level of experience, the data of everyday reality, whose theoretical value Lukacs emphasizes.... They aspire to bear witness to the living thought of one of the great men of our century, and to provide the opportunity to approach this thought by the simplest possible route.". (shrink)

Machine intelligence already helps medical staff with a number of tasks. Ethical decision-making, however, has not been handed over to computers. In this proof-of-concept study, we show how an algorithm based on Beauchamp and Childress’ prima-facie principles could be employed to advise on a range of moral dilemma situations that occur in medical institutions. We explain why we chose fuzzy cognitive maps to set up the advisory system and how we utilized machine learning to train it. We report on the (...) difficult task of operationalizing the principles of beneficence, non-maleficence and patient autonomy, and describe how we selected suitable input parameters that we extracted from a training dataset of clinical cases. The first performance results are promising, but an algorithmic approach to ethics also comes with several weaknesses and limitations. Should one really entrust the sensitive domain of clinical ethics to machine intelligence? (shrink)

The goal of this project is to argue for ethics as a necessary component of the institutional health. The authors offer an epidemiology of ethics for a large, metropolitan, very-high-research-activity university in the U.S. Where epidemiology of a pandemic looks at quantifiable data on infection and exposure rates, control, and broad implications for public health, an epidemiology of ethics looks to parallel data on those same themes. Their hypothesis is that knowing more about how undergraduates are exposed to ethics will (...) help us understand to what extent they are infected with interest in ethics literacy, and potentially what immunity they develop against unethical and unprofessional conduct. These data also tell a story about the ethical health of institutions: to what extent its members are empowered to cultivate a culture of ethics and inoculated against ethical missteps. The authors argue that pro-ethics inoculation at research institutions is shaped by issues of complexity, connotation, and collaboration. These issues make assessment of where ethics is taught all the more difficult. The methodology used in this project can readily be taken up by other institutions, with much to be learned from inter-institutional comparisons about the distribution of ethics across the curriculum and within the disciplines.

Modal fictionalists face a problem that arises due to their possible-world story being incomplete in the sense that certain relevant claims are neither true nor false according to it. It has recently been suggested that this incompleteness problem generalises to other brands of fictionalism, such as fictionalism about composite or mathematical objects. In this paper, I argue that these fictionalist positions are particularly threatened by a generalised incompleteness problem since they cannot emulate the modal fictionalists’ most attractive response. I then (...) defend mathematical and compositional fictionalism by showing that the reasons for which the incompleteness problem has been thought to affect them are mistaken. This leads to the question of whether there are other fictionalist positions to which the problem does in fact generalise. I give a general account of the features of a fictionalist position that generate the incompleteness problem and argue that whenever a fictionalist position does exemplify these features then the problem can be addressed in analogy to the modal fictionalists’ preferred response.

In this paper, we explore an under-investigated question concerning the class of formal models that aim at providing normative guidance. We call such models normative models. In particular, we examine the question of how normative models can successfully exert normative guidance. First, we highlight the absence of a discussion of this question – which is surprising given the extensive debate about the success conditions of descriptive models – and motivate its importance. Second, we introduce and discuss two potential accounts of (...) the success conditions of normative models. Our tentative conclusion is that the second account is more promising. (shrink)

The acceptability of _any_-DPs in existential modal sentences presents a challenge for theories of NPI licensing: existential modal sentences appear to differ substantially from other environments in which _any_-DPs are acceptable (in particular, they lack a downward-entailing operator). One approach to this challenge has been to, first, take _any_-DPs to be subject to an environment-based downward-entailingness condition—they have to occur in an environment that is Strawson downward-entailing with respect to their domain (cf. Kadmon and Landman 1993 )—and, second, to derive (...) such an environment in existential modal sentences by means of exhaustification (e.g., Fox 2007 ). This note presents new evidence for such a two-layered approach (cf. Crnič 2017, 2019 ). The evidence comes from a striking contrast in the behavior of singular vs. plural _any_-DPs in existential modal sentences. The paper concludes by charting some relations between _any_-DPs and other polarity items. (shrink)

ABSTRACT Stephen Gardiner’s A Perfect Moral Storm offers an in-depth analysis of the ethical facets of climate change. In this paper, I contend that he nonetheless overlooks an important structural layer to climate vulnerabilities and injustices because he analyzes them implicitly interactional. I argue that climate change should rather be understood as a form of structural injustice as outlined by Iris M. Young. In this reading, the unjust socio-economic structural processes that give rise to climate change, the production and consumption (...) of fossil fuel energy, are at their core marked by (i) oppressive and dominating power relations that position agents (ii) intersecting with other structural constraints. Crucially, (iii) these structural processes arose historically, persist over time, and entrench the burden on those suffering in the future. This viewpoint improves our understanding of how the climate crisis unfolds over time in a way that augments Gardiner’s analysis. The structural approach can advance the climate justice debate both theoretically and practically. (shrink)

Expectations play an important role in how people plan their lives and pursue their projects. People living in highly industrialized countries share a way of life that comes with high levels of emissions. Their expectations to be able to continue their projects imply their holding expectations to similarly high future levels of personal emissions. We argue that the frustration or undermining of these expectations would cause them significant harm. Further, the article investigates under what conditions people can be thought to (...) hold legitimate expectations, in particular about permissible levels of future emissions. We distinguish differing theories of understanding these conditions, namely authority-based and justice-based theories, that each allows us to systematically distinguish between legitimate and illegitimate expectations. Furthermore, with respect to individuals’ future permissible emissions we give several reasons for holding that such theories cannot identify a particular expectation to a specific level of personal emissions as the only legitimate one. Finally, we argue that the set of legitimate expectations that people hold with respect to a just and effective solution to climate change has normative significance in at least two ways: the differing but equally legitimate expectations ought to be taken into account when justifying what could count as such a solution and when determining the just way of arriving at and implementing such a solution.

Subverting a once widely held Quinean paradigm, there is a growing consensus among philosophers of logic that higher-order quantifiers (which bind variables in the syntactic position of predicates and sentences) are a perfectly legitimate and useful instrument in the logico-philosophical toolbox, while neither being reducible to nor fully explicable in terms of first-order quantifiers (which bind variables in singular term position). This article discusses the impact of this quantificational paradigm shift on metaphysics, focussing on theories of properties, propositions, and identity, (...) as well as on the metaphysics of modality.

The article takes the renewed popularity and interest in epidemiological modelling for Covid-19 as a point of departure to ask how modelling has historically shaped epidemiological reasoning. The focus lies on a particular model, developed in the late 1920s through a collaboration of the former field-epidemiologists and medical officer, Wade Hampton Frost, and the biostatistician and population ecologist Lowell Reed. Other than former approaches to epidemic theory in mathematical formula, the Reed-Frost epidemic theory was materialised in a simple mechanical analogue: (...) a box with coloured marbles and a wooden trough. The article reconstructs how the introduction of this mechanical model has reshaped epidemiological reasoning by shifting the field from purely descriptive to analytical practices. It was not incidental that the history of this model coincided with the foundation of epidemiology as an academic discipline, as it valorised and institutionalised new theoretical contributions to the field. Through its versatility, the model shifted the field’s focus from mono-causal explanations informed by bacteriology, eugenics or sanitary perspectives towards the systematic consideration of epidemics as a set of interdependent and dynamic variables.

Law is perceived as a stabilising mechanism in an everchanging world and, as such, is founded on the quest for the one “true” meaning of legal norms as a basis for the rule of law. But I shall suggest that it is futile to seek a fixed meaning of legal norms or the one “true” method for interpreting them. The argument will be built by first considering the “trialectics” between hermeneutics, linguistics, and jurisprudence, and then taking a systematic approach to (...) law itself, to this end drawing inspiration from the work of Ferdinand de Saussure. I shall finally argue for the necessity of a more procedural understanding of the rule of law. (shrink)

This paper explores one of the main sources of Nietzsche’s knowledge of physiology and considers its relevance for the philosophical study of history. Beginning in 1881, Nietzsche read Der Kampf der Theile im Organismus by Wilhelm Roux, which exposed him to a dysteleological account of organic development emphasising the excitative, assimilative and auto-regulative processes of the body. These processes mediate the effects of natural selection. His reading contributed to a physiological understanding of history that borrowed Roux’s description of physiological processes. (...) This physiological description of history proceeded from the similarity between the body’s mediation of its milieu and history’s mediation of the past. (shrink)

Functionalism about kinds is still the dominant style of thought in the special sciences, like economics, psychology, and biology. Generally construed, functionalism is the view that states or processes can be individuated based on what role they play rather than what they are constituted of or realized by. Recently, Weiskopf has posited a reformulation of functionalism on the model-based approach to explanation. We refer to this reformulation as ‘new functionalism’. In this paper, we seek to defend new functionalism and to (...) recast it in light of the concrete explanatory aims of the special sciences. In particular, we argue that the assessment of the explanatory legitimacy of a functional kind needs to take into account the explanatory purpose of the model in which the functional kind is employed. We aim at demonstrating this by appealing to model-based explanations from the social and behavioral sciences. Specifically, we focus on preferences and signals as functional kinds. Our argument is intended to have the double impact of deflecting criticisms against new functionalism from the perspective of mechanistic decomposition while also expanding the scope of new functionalism to encompass the social and behavioral sciences.

Legitimate expectations should be considered in the transition to a low-carbon society. After explaining under what conditions and circumstances expectations are legitimate, this paper shows that those expectations whose frustration undermines the ability to plan, infringes basic moral rights, or is extremely costly for its bearer might justify a deviation in the baseline of justice in favour of the expectation holder. People should be notified about the likely frustration of their expectations so that they can avoid the frustration of their (...) expectations, adapt their life plans and minimise costs. Since the frustration of legitimate expectations seems unavoidable in the transformation to a low-carbon society, priority should be given to the protection of the expectations of those who cannot be materially compensated. Still, if two groups are eligible for material compensation, we should give priority to protecting the expectation of those who cannot continue with the same life plan as before if their expectations are frustrated.

Using a countable support product of creature forcing posets, we show that consistently, for uncountably many different functions the associated Yorioka ideals’ uniformity numbers can be pairwise different. In addition we show that, in the same forcing extension, for two other types of simple cardinal characteristics parametrised by reals, for uncountably many parameters the corresponding cardinals are pairwise different.

The internet has become an ubiquitous epistemic source. However, it comes with several drawbacks. For instance, the world wide web seems to foster filter bubbles and echo chambers and includes search results that promote bias and spread misinformation. Richard Heersmink suggests online intellectual virtues to combat these epistemically detrimental effects . These are general epistemic virtues applied to the online environment based on our background knowledge of this online environment. I argue that these online intellectual virtues also demand a particular (...) view of cognitive integration. Online intellectual virtues are incompatible with a popular conception of extended minds proposed by Andy Clark and David Chalmers . I suggest that if we want to hold on to both a conception of online intellectual virtues and some conception of the extended mind, we have to accept a more gradual theory of cognitive integration along the lines of second-wave theories of the extended mind.

Higher-order realists about properties express their view that there are properties with the help of higher-order rather than first-order quantifiers. They claim two types of advantages for this way of formulating property realism. First, certain gridlocked debates about the nature of properties, such as the immanentism versus transcendentalism dispute, are taken to be dissolved. Second, a further such debate, the tropes versus universals dispute, is taken to be resolved. In this paper I first argue that higher-order realism does not in (...) fact resolve the tropes versus universals dispute. In a constructive spirit, I then develop higher-order realism in a way that leads to a dissolution, rather than a resolution, of this dispute too. (shrink)

The distribution of the focus particle even is constrained: if it is adjoined at surface structure to an expression that is entailed by its focus alternatives, as in even once, it must be appropriately embedded to be acceptable. This paper focuses on the context-dependent distribution of such occurrences of even in the scope of non-monotone quantifiers. We show that it is explained on the assumption that even can move at LF Syntax and semantics, 1979). The analysis is subsequently extended to (...) occurrences of negative polarity items in these environments, which mirror the abovementioned distribution of even and which invalidate standard characterizations of NPI licensing conditions in terms of downward-entailingness. The idea behind the extension is that NPIs denote weak elements that are associates of covert even. The paper concludes by discussing two comprehensive theories of NPI licensing and how our proposal relates to them. (shrink)

Neurological disorders of body representation have for a long time suggested the importance of multisensory processing of bodily signals for self-consciousness. One such group of disorders – illusory own body perceptions affecting the entire body – has been proposed to be especially relevant in this respect, based on neurological data as well as philosophical considerations. This has recently been tested experimentally in healthy subjects showing that integration of multisensory bodily signals from the entire body with respect to the three aspects: (...) self-location, first-person perspective, and self-location, is crucial for bodily self-consciousness. Here we present clinical and neuroanatomical data of two neurological patients with paroxysmal disorders of full body representation in whom only one of these aspects, self-identification, was abnormal. We distinguish such disorders of global body representation from related but distinct disorders and discuss their relevance for the neurobiology of bodily self-consciousness. (shrink)

The evolutionary circuit design is an approach allowing engineers to realize computational devices. The evolved computational devices represent a distinctive class of devices that exhibits a specific combination of properties, not visible and studied in the scope of all computational devices up till now. Devices that belong to this class show the required behavior; however, in general, we do not understand how and why they perform the required computation. The reason is that the evolution can utilize, in addition to the (...) “understandable composition of elementary components”, material-dependent constructions and properties of environment (such as temperature, electromagnetic field etc.) and, furthermore, unknown physical behaviors to establish the required functionality. Therefore, nothing is known about the mapping between an abstract computational model and its physical implementation. The standard notion of computation and implementation developed in computer science as well as in cognitive science has become very problematic with the existence of evolved computational devices. According to the common understanding, the evolved devices cannot be classified as computing mechanisms. (shrink)

Jean Grondin completes the first history of metaphysics and respects both the analytical and the Continental schools while transcending the theoretical limitations of each. He reviews seminal texts by Parmenides, Plato, Aristotle, Plotinus, and Augustine. He follows the theological turn in the metaphysical thought of Avicenna, Anselm, Aquinas, and Duns Scotus, and he revisits Descartes and the cogito; Spinoza and Leibniz's rationalist approaches; Kant's reclaiming of the metaphysical tradition; and post-Kantian practice up to Hegel. He engages with twentieth century innovations (...) that upended the discipline, particularly Heidegger's revival of the question of Being and the rediscovery of the metaphysics of existence by Sartre and the Existentialists, language by Gadamer and Derrida, and transcendence by Levinas. Metaphysics is often dismissed as a form or epoch of philosophy that must be overcome, yet by promoting a full understanding of its platform and processes, Grondin reveals its cogent approach to reality and foundational influence on modern philosophy and science. By restoring the value of metaphysics for contemporary audiences, Grondin showcases the rich currents and countercurrents of metaphysical thought and its future possibilities. (shrink)

When economists perform experiments, they do so typically in one of two traditions: cognitive psychology experiments in the heuristics and biases tradition (H&B-experiments) and experimental economics in the tradition of Vernon Smith. What sets these two traditions apart? In this paper, I offer a novel conceptualization of their pervasive disagreements. Focusing on how each camp approaches preferences, one of the most fundamental concepts in economics, I argue that experimental economics can be reconstructed as holding that the constituents of preferences can (...) be partially located in agents’ environments, while H&B-experiments implicitly assume that the constituents of preferences are entirely located within agents’ bodies. The paper (i) outlines how my reconstruction can account for the disagreement between the two paradigms, (ii) defends the plausibility of this reconstruction, and (iii) highlights its implications for the debate about the nature of preferences in economics.

We seem to ascribe mental states and agency to groups. We say ‘Google knows such-and-such,’ or ‘Amazon intends to do such-and-such.’ This observation of ordinary parlance also found its way into philosophical accounts of social groups and collective intentionality. However, these discussions are usually quiet about how groups self-ascribe their own beliefs and intentions. Apple might explain to its shareholders that it intends to bring a new iPhone to the market next year. But how does Apple know what it intends? (...) How do groups get to know their own mental states? This is the question of collective self-knowledge. I argue that collective self-knowledge is a distinct phenomenon that deserves our attention. In particular I suggest: that we should be interested in collective self-knowledge, because our behaviour indicates that we already engage with collective self-knowledge in practice; that groups can collectively avow, which indicates that they have privileged and peculiar access to their own intentional states; and that collective self-knowledge is not reducible to intentional states of individuals and therefore is an independent explanandum.

Is it fair to leave the next generation a public debt? Is it defensible to impose legal rules on them through constitutional constraints? From combating climate change to ensuring proper funding for future pensions, concerns about ethics between generations are everywhere. In this volume sixteen philosophers explore intergenerational justice. Part One examines the ways in which various theories of justice look at the matter. These include libertarian, Rawlsian, sufficientarian, contractarian, communitarian, Marxian and reciprocity-based approaches. In Part Two, the authors look (...) more specifically at issues relevant to each of these theories, such as motivation to act fairly towards future generations, the population dimension, the formation of preferences through education and how they impact on our intergenerational obligations, and whether it is fair to rely on constitutional devices.

According to Frege, expressions shift their reference when they occur in indirect contexts: in “Anna believes that Plato is wise” the expression “Plato” no longer refers to Plato but to what is ordinarily its sense. Many philosophers, including Carnap, Davidson, Burge, Parsons, Kripke and Künne, believe that on Frege's view the iteration of indirect context creating operators gives rise to an infinite hierarchy of senses. While the former two take this to be problematic, the latter four welcome the hierarchy with (...) open arms. In this paper I argue that the hierarchy should be avoided and that it can be avoided.

Hybrid contingentism combines first-order contingentism, the view that it is contingent what individuals there are, with higher-order necessitism, the view that it is non-contingent what properties and propositions there are (where these are conceived as entities in the range of appropriate higher-order quantifiers). This combination of views avoids the most delicate problems afflicting alternative contingentist positions while preserving the central contingentist claim that ordinary, concrete entities exist contingently. Despite these attractive features, hybrid contingentism is usually faced with rejection. The main (...) reason for this is an objection that crucially involves haecceitistic properties, properties such as being identical to Plato or being identical to Aristotle. The objection alleges that by accepting the necessary existence of such haecceities, hybrid contingentists incur an explanatory commitment that they are unable to discharge, namely that of explaining how it is that certain haecceities ‘lock onto’ their target individuals even when those individuals are absent. To defend hybrid contingentism against this charge, I first clarify the haecceities objection in several respects and consider, in particular, what notion of explanation the objection is operating with. After arguing that it can be fruitfully understood as a challenge to provide metaphysical grounds for certain haecceity facts, I develop a contingentist response to the objection that draws on recent work on the connection between ground and essence.

Groups can be epistemically vicious just like individuals. And just like individuals, groups sometimes want to do something about their vices. They want to change. However, intentionally combating one’s own vices seems impossible without detecting those vices first. Self-knowledge seems to provide a first step towards changing one’s own epistemic vices. I argue that groups can acquire self-knowledge about their epistemic vices and I propose an account of such collective self-knowledge. I suggest that collective self-knowledge of vices is partially based (...) on evidence that a group can generate by performing internal promptings. Whereas these promptings are done mentally in individual self-knowledge, these promptings are done by interactions of group members in the collective case. The group can then acquire inferential self-knowledge of their vices based on the evidence generated by the interactions within the group. Groups thereby bring themselves into a position from which they can combat and change those vices intentionally. (shrink)
