Our current understanding of ‘fake news’ is not in good shape. On the one hand, this category seems to be urgently needed for an adequate understanding of the epistemology in the age of the internet. On the other hand, the term has an unstable ordinary meaning and the prevalent accounts which all relate fake news to epistemically bad attitudes of the producer lack theoretical unity, sufficient extensional adequacy, and epistemic fruitfulness. I will therefore suggest an alternative account of fake news (...) that is meant as an explication rather than a traditional conceptual analysis of the term and that understands fake news solely from the consumer’s perspective. I will argue that this new account has the required theoretical unity, that it is epistemically highly fruitful, and that it is still very close to the ordinary usage. I conclude with addressing some of the main objections to this view. (shrink)

Is it possible for an individual that has gone out of being to come back into being again? The English Aristotelian, Thomas White, argued that it is not. Thomas Hobbes disagreed, and used the case of the Ship of Theseus to argue that individuals that have gone out of being may come back into being again. This paper provides the first systematic account of their arguments. It is doubtful that Hobbes has a consistent case against White. (...) Still his criticism may have prompted White to clarify his views on identity over time in his later work. (shrink)

In this paper I will offer a comprehensive defense of the safety account of knowledge against counterexamples that have been recently put forward. In Sect. 2, I will discuss different versions of safety, arguing that a specific variant of method-relativized safety is the most plausible. I will then use this specific version of safety to respond to counterexamples in the recent literature. In Sect. 3, I will address alleged examples of safe beliefs that still constitute Gettier cases. In Sect. 4, (...) I will discuss alleged examples of unsafe knowledge. In Sect. 5, I will address alleged cases of safe belief that do not constitute knowledge for non-Gettier reasons. My overall goal is to show that there are no successful counterexamples to robust anti-luck epistemology and to highlight some major presuppositions of my reply. (shrink)

Would compulsory treatment or vaccination for Covid-19 be justified? In England, there would be significant legal barriers to it. However, we offer a conditional ethical argument in favour of allowing compulsory treatment and vaccination, drawing on an ethical comparison with external constraints—such as quarantine, isolation and ‘lockdown’—that have already been authorised to control the pandemic. We argue that, if the permissive English approach to external constraints for Covid-19 has been justified, then there is a case for a similarly permissive (...) approach to compulsory medical interventions.

Can there be a "reflexive" or presuppositional, reasonably non-rejectable grounding of a Forst-type right to justification, or of a meaningful form of constitutive discursive standing? The paper argues that this is not so, and this for reasons that reflect more general limitations of presuppositional arguments for relevantly contested conclusions. To this end, the paper critically engages Forst's "reflexive" argument for human rights. It also considers O'Neill's presuppositional attempt to defend a form of cosmopolitanism, as well as the attempt to anchor (...) constructivist conclusions in the meaning of the word "reasonable".

Geoscience research may upset people even though it is ethically acceptable. In this paper we attempt to explore three questions about such research. It will turn out that (1) under most circumstances ethical but upsetting geoscience research is morally permissible, (2) revising this research in response to upset-induced external interference is morally impermissible in the absence of strong countervailing pragmatic reasons and attempts to reduce upset, and (3) potentially upsetting geoscience research ought to be communicated truthfully and tailored to each (...) individual situation. These general propositions are applied to a case of ethical but upsetting research that we ourselves are currently involved. (shrink)

Typically, nudging is a technique for steering the choices of people without giving reasons or using enforcement. In benevolent cases, it is used when people are insufficiently responsive to reason. The nudger triggers automatic cognitive mechanisms – sometimes even biases – in smart ways in order to push irrational people in the right direction. Interestingly, this technique can also be applied to doxastic attitudes. Someone who is doxastically unresponsive to evidence can be nudged into forming true beliefs or doxastic attitudes (...) that are propositionally justified. When doxastic nudging uses non-rational mechanisms, the worry is that nudging cannot result in justified beliefs or knowledge, as the resulting doxastic attitudes lack the right kind of basis. In this paper, I will argue that given the right background views about knowledge, justified beliefs and the relevant processes, epistemic nudging is possible even in these cases. That is, all kinds of nudging can – in appropriate circumstances – produce justified beliefs or knowledge in the nudgee. (shrink)

Intuitively, many people seem to hold that engaging in acts of virtual murder in videogames is morally permissible, whereas engaging in acts of virtual child molestation is morally impermissible. The Gamer’s Dilemma (Luck in Ethics Inf Technol 11:31–36, 2009) challenges these intuitions by arguing that it is unclear whether there is a morally relevant difference between these two types of virtual actions. There are two main responses in the literature to this dilemma. First, attempts to resolve the dilemma by defending (...) an account of the relevant moral differences between virtual murder and virtual child molestation. Second, attempts to dissolve the dilemma by undermining the intuitions that ground it. In this paper, we argue that a narrow version of the Gamer’s Dilemma seems to survive attempts to resolve or dissolve it away entirely, since neither approach seems to be able to solve the dilemma for all cases. We thus provide a contextually sensitive version of the dilemma that more accurately tracks onto the intuitions of gamers. However, we also argue that the intuitions that ground the narrow version of the Dilemma may not have a moral foundation, and we put forward alternative non-moral normative foundations that seem to better account for the remaining intuitive difference between the two types of virtual actions. We also respond to proposed solutions to the Gamer’s Dilemma in novel ways and set out areas for future empirical work in this area. (shrink)

"Meritocracy" has historically been understood in two ways. The first is as an approach to governance. On this understanding, we seek to put meritorious (somehow defined) people into public office to the benefit of society. This understanding has its roots in Confucius, its scope is political offices, and its justification is consequentialist. The second understanding of "meritocracy" is as a theory of justice. We distribute in accordance with merit in order to give people the things that they deserve, as justice (...) demands. This understanding has its roots in Aristotle, its scope is social goods broadly, and its justification is deontological. In this article, I discuss the differences--especially the conceptual differences--between these two, prima facie distinct, meritocratic traditions. I also argue that despite their differences Eastern Meritocracy and Western Meritocracy are harmonious. In Section I of the article I introduce the two meritocratic traditions through, in part, a highly abbreviated history of talk about "merit" and "meritocracy" in Chinese and Western philosophy. In Section II, I discuss a number of conceptual issues and partition meritocratic theories in accordance with their scopes and normative justifications. I also discuss two scenarios. In one scenario, Eastern Meritocracy appears to deliver the right result and Western Meritocracy, the wrong result. In the other scenario, vice versa. Finally, in Section III, I argue that Eastern Meritocracy and Western Meritocracy are each special cases of a single, compelling notion of "meritocracy.". (shrink)

Experimental ethicists investigate traditional ethical questions with non-traditional means, namely with the methods of the empirical sciences. Studies in this area have made heavy use of philosophical thought experiments such as the well-known trolley cases. Yet, the specific function of these thought experiments within experimental ethics has received little consideration. In this paper we attempt to fill this gap. We begin by describing the function of ethical thought experiments, and show that these thought experiments should not only be classified according (...) to their function but also according to their scope. On this basis we highlight several ways in which the use of thought experiments in experimental ethics can be philosophically relevant. We conclude by arguing that experimental philosophy currently only focuses on a small subcategory of ethical thought experiments and suggest a broadening of its research agenda. (shrink)

Though the social world is real and objective, the way that social facts arise out of other facts is in an important way shaped by human thought, talk and behaviour. Building on recent work in social ontology, I describe a mechanism whereby this distinctive malleability of social facts, combined with the possibility of basic human error, makes it possible for a consistent physical reality to ground an inconsistent social reality. I explore various ways of resisting the prima facie case (...) for social inconsistency. I conclude, however, that the prima facie case survives scrutiny, and draw out some of the ramifications.

Taurek cases focus a choice between two views of permissible action, Can Save One and Must Save Many . It is argued that Taurek cases do illustrate the rationale for Can Save One , but existing views do not highlight the fact that this is because they are examples of claims grounded on non-comparative justice. To act to save the many solely because they form a group is to discriminate against the one for an irrelevant reason. That is a canonical (...) form of non-comparative injustice. The error lies in taking a contingency of some presentations of some Taurek cases, namely, that they involve distribution, to introduce the claims of comparative as opposed to non-comparative justice. But cases of non-comparative justice can, contingently, also involve distribution. In order to settle which form of justice applies it is necessary to examine the nature of the distribution involved and the nature of “classes” to which individuals can be assigned. (shrink)

Climate change increases the frequency and intensity of certain kinds of natural hazard events in alpine areas. This interdisciplinary study addresses the hypothetical possibility of relocating the residents of three alpine areas in Austria: the Sölk valleys, the Johnsbach valley, and the St. Lorenzen/Schwarzenbach valleys. Our particular focus is on these residents’ expectations about such relocations. We find that (1) many residents expect that in the next decades the state will provide them with a level of natural hazards protection, aid, (...) and relief that allows them to continue to live in these valleys; (2) this expectation receives some legal protection but only when it is associated with fundamental rights; and (3) the expectation is morally significant, i.e., it ought to be considered in assessing the moral rightness or justness of relocation policies. These results suggest legal changes and likely extend to many other (Austrian) alpine areas as well. (shrink)

Much attention has recently been paid to the idea, which I label ‘External World Acquaintance’ (EWA), that the phenomenal character of perceptual experience is partially constituted by external features. One motivation for EWA which has received relatively little discussion is its alleged ability to help deal with the ‘Explanatory Gap’ (e.g. Fish 2008, 2009, Langsam 2011, Allen 2016). I provide a reformulation of this general line of thought, which makes clearer how and when EWA could help to explain the specific (...) phenomenal nature of visual experience. In particular, I argue that by focusing on the different kinds of perceptual actions that are available in the case of visual spatial vs. colour perception, we get a natural explanation for why we should expect the specific nature of colour phenomenology to remain less readily intelligible than the specific nature of visual spatial phenomenology.

This paper examines the differences between moralist, realist, and pragmatist approaches to political legitimacy by articulating their largely implicit views of judgment. Three claims are advanced. First, the salient opposition among approaches to legitimacy is not between “moralism” and “realism.” Recent realist proposals for rethinking legitimacy share with moralist views a distinctive form, called “normativism”: a quest for knowledge of principles that solve the question of legitimacy. This assumes that judging legitimacy is a matter of applying such principles to a (...) case at hand. Second, neither Rawls nor Habermas is a normativist about political legitimacy. The principles of legitimacy they proffer claim to express rather than adjudicate the legitimacy of a liberal-democratic regime, and thus cannot solve the question of legitimacy at a fundamental level. But perhaps we should question the normativist aspiration to theoretically resolving the problem to begin with. My third claim is that a “pragmatist” approach enables us to rethink political legitimacy more deeply by shifting focus from the articulation of principles to the activity of judging. Implicit in Rawls’s and Habermas’s theories I then find clues towards an alternative account of judgment, in which the question of legitimacy calls not for theoretical resolution but for ongoing practical engagement.

In Anglo-Saxon philosophy of science there is strong conviction that idealist philosophy of science on the the one hand and serious science and philosophy of science on the other do not go well together. In this paper I argue that this sweeping dismissal of the idealist tradition may have been too hasty. They may be some valuable insights for which it is striving. A promising case in question is provided by Ernst Cassirer’s Neo-Kantian „Critical Idealism“ that he put forward (...) in the first decades of the past century, or so I’d like to argue. (shrink)

Disagreement is a ubiquitous feature of human life, and philosophers have dutifully attended to it. One important question related to disagreement is epistemological: How does a rational person change her beliefs (if at all) in light of disagreement from others? The typical methodology for answering this question is to endorse a steadfast or conciliatory disagreement norm (and not both) on a priori grounds and selected intuitive cases. In this paper, I argue that this methodology is misguided. Instead, a thoroughgoingly Bayesian (...) strategy is what's needed. Such a strategy provides conciliatory norms in appropriate cases and steadfast norms in appropriate cases. I argue, further, that the few extant efforts to address disagreement in the Bayesian spirit are laudable but uncompelling. A modelling, rather than a functional, approach gets us the right norms and is highly general, allowing the epistemologist to deal with (1) multiple epistemic interlocutors, (2) epistemic superiors and inferiors (i.e. not just epistemic peers), and (3) dependence between interlocutors.

For the past half-century, both jurisprudence and epistemology have been haunted by questions about why individual evidence (i.e., evidence which picks out a specific individual) can sufficiently justify a guilty or liable verdict while bare statistical evidence (i.e., statistical evidence which does not pick out a specific individual) does not sufficiently justify such a verdict. This thesis examines three popular justifications for such a disparity in verdicts – Judith Jarvis Thomson’s causal account, Enoch et al.’s sensitivity account, and Sarah Moss’ (...) knowledge-first account, before critiquing each in turn. After such an analysis, the thesis then defends the claim that legal verdicts require the factfinder (e.g., the judge or jury) to have a justified de re belief (i.e., a belief about a specific object – namely the defendant), and that this doxastic requirement justifies the disparity in rulings, as it is epistemically insufficient to justify a de re belief based on bare statistical evidence alone. A brief account of how these beliefs are formed and spread is also given. After making such a distinction, the thesis then formalizes the burdens of proof of the preponderance of the evidence and beyond a reasonable doubt using the de re/de dicto distinction. Finally, the thesis pre-empts possible objections, namely by providing an account of DNA evidence as individual evidence and giving an account of how false convictions can occur on the de re view of legal proof.

Abstract. The aim of this paper is to present a topological method for constructing discretizations (tessellations) of conceptual spaces. The method works for a class of topological spaces that the Russian mathematician Pavel Alexandroff defined more than 80 years ago. Alexandroff spaces, as they are called today, have many interesting properties that distinguish them from other topological spaces. In particular, they exhibit a 1-1 correspondence between their specialization orders and their topological structures. Recently, a special type of Alexandroff spaces was (...) used by Ian Rumfitt to elucidate the logic of vague concepts in a new way. According to his approach, conceptual spaces such as the color spectrum give rise to classical systems of concepts that have the structure of atomic Boolean algebras. More precisely, concepts are represented as regular open regions of an underlying conceptual space endowed with a topological structure. Something is subsumed under a concept iff it is represented by an element of the conceptual space that is maximally close to the prototypical element p that defines that concept. This topological representation of concepts comes along with a representation of the familiar logical connectives of Aristotelian syllogistics in terms of natural settheoretical operations that characterize regular open interpretations of classical Boolean propositional logic. In the last 20 years, conceptual spaces have become a popular tool of dealing with a variety of problems in the fields of cognitive psychology, artificial intelligence, linguistics and philosophy, mainly due to the work of Peter Gärdenfors and his collaborators. By using prototypes and metrics of similarity spaces, one obtains geometrical discretizations of conceptual spaces by so-called Voronoi tessellations. These tessellations are extensionally equivalent to topological tessellations that can be constructed for Alexandroff spaces. Thereby, Rumfitt’s and Gärdenfors’s constructions turn out to be special cases of an approach that works for a more general class of spaces, namely, for weakly scattered Alexandroff spaces. This class of spaces provides a convenient framework for conceptual spaces as used in epistemology and related disciplines in general. Alexandroff spaces are useful for elucidating problems related to the logic of vague concepts, in particular they offer a solution of the Sorites paradox (Rumfitt). Further, they provide a semantics for the logic of clearness (Bobzien) that overcomes certain problems of the concept of higher2 order vagueness. Moreover, these spaces help find a natural place for classical syllogistics in the framework of conceptual spaces. The crucial role of order theory for Alexandroff spaces can be used to refine the all-or-nothing distinction between prototypical and nonprototypical stimuli in favor of a more fine-grained gradual distinction between more-orless prototypical elements of conceptual spaces. The greater conceptual flexibility of the topological approach helps avoid some inherent inadequacies of the geometrical approach, for instance, the so-called “thickness problem” (Douven et al.) and problems of selecting a unique metric for similarity spaces. Finally, it is shown that only the Alexandroff account can deal with an issue that is gaining more and more importance for the theory of conceptual spaces, namely, the role that digital conceptual spaces play in the area of artificial intelligence, computer science and related disciplines. Keywords: Conceptual Spaces, Polar Spaces, Alexandroff Spaces, Prototypes, Topological Tessellations, Voronoi Tessellations, Digital Topology. (shrink)

A prevalent assumption in metaethics is that people believe in moral objectivity. If this assumption were true then people should believe in the possibility of objective moral progress, objective moral knowledge, and objective moral error. We developed surveys to investigate whether these predictions hold. Our results suggest that, neither abstractly nor concretely, people dominantly believe in the possibility of objective moral progress, knowledge and error. They attribute less objectivity to these phenomena than in the case of science and no (...) more, or only slightly more, than in the cases of social conventions and personal preferences. This finding was obtained for a regular sample as well as for a sample of people who are particularly likely to be reflective and informed (philosophers and philosophy students). Our paper hence contributes to recent empirical challenges to the thesis that people believe in moral objectivity. (shrink)

In this paper, I argue that the two most common views of how to respond rationally to peer disagreement–the Total Evidence View (TEV) and the Equal Weight View (EWV)–are both inadequate for substantial reasons. TEV does not issue the correct intuitive verdicts about a number of hypothetical cases of peer disagreement. The same is true for EWV. In addition, EWV does not give any explanation of what is rationally required of agents on the basis of sufficiently general epistemic principles. I (...) will then argue that there is a genuine alternative to both views–the Preemption View (PV)–that fares substantially better in both respects. I will give an outline and a detailed defense of PV in the paper. (shrink)

Abstract. Traditional epistemology of knowledge and belief can be succinctly characterized as JTB-epistemology, i.e., it is characterized by the thesis that knowledge is justified true belief. Since Gettier’s trail-blazing paper of 1963 this account has become under heavy attack. The aim of is paper is to study the Gettier problem and related issues in the framework of topological epistemic logic. It is shown that in the framework of topological epistemic logic Gettier situations necessarily occur for most topological models of knowledge (...) and belief. On the other hand, there exists a special class of topological models (based on so called nodec spaces) for which traditional JTB-epistemology is valid. Further, it is shown that for each topological model of Stalnaker’s combined logic KB of knowledge and belief a canonical JTB-model (its JTB-doppelganger) can be constructed that shares many structural properties with the original model but is free of Gettier situations. The topological model and its JTB-doppelganger both share the same justified belief operator and have very similar knowledge operators. Seen from a somewhat different perspective, the JTB-account of epistemology amounts to a simplification of a more general epistemological account of knowledge and belief that assumes that these two concepts may differ in some cases. The JTB-account of knowledge and belief assumes that the epistemic agent’s cognitive powers are rather large. Thereby in the JTB-epistemology Gettier cases do not occur. Eventually, it is shown that for all topological models of Stalnaker’s KB-logic Gettier situations are topologically characterized as nowhere dense situations. This entails that Gettier situations are epistemologically invisible in the sense that they can neither be known nor believed with justification with respect to the knowledge operator and the belief operator of the models involved.

Abstract. Gettier’s famous examples intended to show that knowledge cannot always be equated with justified true belief. The Gettier problem can also be considered as a problem for topological epistemic logic: If knowledge and justified belief are conceived as topological operators K and B on topological spaces (to be considered as universes of possible worlds), one may ask whether it happens that there is a proposition A such that KA ≠ A & BA or not. If this is the (...) class='Hi'>case, the epistemological logic defined by the topological operators K and B may be said to be non-traditional since there is for them a “Gettier proposition” where knowledge does not coincide with justified true belief. As far as we know, for the first time, this topological Gettier problem is discussed in Steinvold’s PhD dissertation (Steinsvold 2012). In Baltag, Bezhanishvili, Özgün, and Smets (2013), Steinvold’s co-derived set account is criticized since it can be easily “Gettierized”. Baltag et alii claim (without proof) that their topological account of Stalnaker’s logic KB of knowledge and belief does not have this flaw. In the following we will give some topological conditions that determine whether a topological KB model does or does not cope with the Gettier challenge. First, it will be shown that every KB model defines a (topologically slightly simplified) model that is rather similar to it but a is a model of traditional JTB (knowledge = justified true belief) logic of knowledge and belief. The existence of such doppelgangers of all KB models may be read as a qualified and partial topological rehabilitation of traditional JTB epistemology. Second, we consider the Gettier problem for a special class of models of Stalnaker’s combined logic of knowledge and belief KB, namely, for T0 Alexandroff spaces. We prove that, that almost all Alexandroff spaces do not face Gettier counterexamples. Third, we prove that the Stone spaces of Boolean algebras of regular closed subsets of Hausdorff (or T2) spaces X do not face Gettier counterexamples if the X are not pseu–docompact, and these Stone spaces do face Gettier counterexamples for compact spaces X. Succinctly formulated, Stalnaker’s KB logic of knowledge and belief can avoid Gettier problems for some models, while it falls back to traditional pre-Gettier JTB epistemology for other models. In contrast, co-derived set semantics is doomed to fail always in the sense that its models always fall prey to Gettier counterexamples. (shrink)

In philosophy, as in many other disciplines and domains, stable disagreement among peers is a widespread and well-known phenomenon. Our intuitions about paradigm cases, e.g. Christensen's Restaurant Case, suggest that in such controversies suspension of judgment is rationally required. This would prima facie suggest a robust suspension of judgment in philosophy. But we are still lacking a deeper theoretical explanation of why and under what conditions suspension is rationally mandatory. In the first part of this paper I will focus (...) on this question. After a critical survey of some recent alternative approaches (diversity as a thread to the reliability, decision problem, acquisition of undercutting defeaters), I will argue that in fact discovering disagreement with an opponent provides me with a rebutting defeater, but only if some further non-trivial conditions are satisfied - among them my acknowledging her as my reliability peer. In the second part of the paper I will explore in more detail the skeptical implications this account has for philosophy. Here, I will defend two claims. First, skepticism about philosophy is mandatory only if the relevant peerness assumption can be justified. Second, in philosophy there is no basis available that would support the relevant peerness assumption. If this is correct, we are not forced into skepticism about philosophy and may rationally retain our philosophical beliefs even in the face of controversy. (shrink)

This paper argues that instrumental rationality is more permissive than expected utility theory. The most compelling instrumentalist argument in favour of separability, its core requirement, is that agents with non-separable preferences end up badly off by their own lights in some dynamic choice problems. I argue that once we focus on the question of whether agents’ attitudes to uncertain prospects help define their ends in their own right, or instead only assign instrumental value in virtue of the outcomes they may (...) lead to, we see that the argument must fail. Either attitudes to prospects assign non-instrumental value in their own right, in which case we cannot establish the irrationality of the dynamic choice behaviour of agents with non-separable preferences. Or they don’t, in which case agents with non-separable preferences can avoid the problematic choice behaviour without adopting separable preferences. (shrink)

As engineering applications require management of ever larger volumes of data, ontologies offer the potential to capture, manage, and augment data with the capability for automated reasoning and semantic querying. Unfortunately, considerable barriers hinder wider deployment of ontologies in engineering. Key among these is lack of a shared top-level ontology to unify and organise disparate aspects of the field and coordinate co-development of orthogonal ontologies. As a result, many engineering ontologies are limited to their scope, and functionally difficult to extend (...) or interoperate with other engineering ontologies. This paper demonstrates how the use of a top-level ontology, specifically the Basic Formal Ontology (BFO), greatly facilitates interoperability of multiple engineering-related ontologies. We constructed a system of formal linked ontologies by re-engineering legacy ontologies to be conformant with BFO and developing new BFO-conformant ontologies to capture knowledge in the engineering design, enterprise, human factors, manufacturing, and application domain of additive manufacturing. The resulting Integrated Framework for Additively Manufactured Products (IFAMP), including the body knowledge instantiated on its basis, serve as the basis for a proposed Design with Additive Manufacturing Method (DWAM), which we believe can support the design of innovative products with semantically enhanced ideation tools and enhanced access to application domain knowledge. The method and its facilitation through the ontological framework are demonstrated using a case study in medicine. (shrink)

Kriegel described the problem of intentional inexistence as one of the ‘perennial problems of philosophy’, 307–340, 2007: 307). In the same paper, Kriegel alluded to a modal realist solution to the problem of intentional inexistence. However, Kriegel does not state by name who defends the kind of modal realist solution he has in mind. Kriegel also points out that even what he believes to be the strongest version of modal realism does not pass the ‘principle of representation’ and thus modal (...) realism is not an adequate solution to the problem of intentional inexistence. In this paper, I respond to Kriegel by defending a modal realist solution that he did not consider in 2007, called ‘extended modal realism’. EMR is a version of modal realism where possible worlds are not completely isolated as they are under the Lewisian model. Rather, under EMR worlds are, in a way, spatiotemporally related. The fact EMR worlds are related allows EMR to sufficiently pass the principle of representation and thus can be deemed a legitimate solution to the problem of intentional inexistence. I conclude that either EMR can pass the principle of representation in some cases or, and I think the more sensible option, we give up on the principle of representation altogether. (shrink)

Instability occurs when the very fact of choosing one particular possible option rather than another affects the expected values of those possible options. In decision theory: An act is stable iff given that it is actually performed, its expected utility is maximal. When there is no stable choice available, the resulting instability can seem to pose a dilemma of practical rationality. A structurally very similar kind of instability, which occurs in cases of anti-expertise, can likewise seem to create dilemmas of (...) epistemic rationality. One possible line of response to such cases of instability, suggested by both Jeffrey (1983) and Sorensen (1987), is to insist that a rational agent can simply refuse to accept that such instability applies to herself in the first place. According to this line of thought it can be rational for a subject to discount even very strong empirical evidence that the anti-expertise condition obtains. I present a new variety of anti-expertise condition where no particular empirical stage-setting is required, since the subject can deduce a priori that an anti-expertise condition obtains. This kind of anti-expertise case is therefore not amenable to the line of response that Jeffrey and Sorensen recommend. (shrink)

I consider cases where you increase the risk that, e.g., someone will die, without increasing the risk that you will kill them: in particular, cases in which that increasing of risk is accompanied by a decreasing of risk of the same degree such that the risk imposition has been offset. I defend the moral legitimacy of such offsetting, including carbon-offsetting.

I develop a new theodicy in defense of Anselmian theism, one that has several advantages over traditional and recent replies to the Problem of Evil. To make my case, I first explain the value of a positive trajectory: a forward-in-time decrease in ‘first-order-gratuitous’ evil: evil that is not necessary for any equal-or-greater first-order good, but may be necessary for a higher-order good, such as the good of strongly positive axiological trajectory. Positive trajectory arguably contributes goodness to a world in (...) proportion to the magnitude of this trajectory, and worlds that contain first-order-gratuitous evil thereby have the potential to contain a strongly positive trajectory. This would arguably explain why God would permit first-order-gratuitous evils: he may be indifferent between a world with no first-order-gratuitous evil and a world with some first-order-gratuitous evil but a strongly positive trajectory. Next, I answer the most salient objections to this theodicy. Finally, I explain how this theodicy is superior to some common theodicies. (shrink)

According to Sparse views of perceptual content, the phenomenal character of perceptual experience is exhausted by the experiential presentation of ‘low-level’ properties such as (in the case of vision) shapes, colors, and textures Whereas, according to Rich views of perceptual content, the phenomenal character of perceptual experience can also sometimes involve experiencing ‘high-level’ properties such as natural kinds, artefactual kinds, causal relations, linguistic meanings, and moral properties. An important dialectical tool in the debate between Rich and Sparse theorists is (...) the so-called ‘method of phenomenal contrast’. I explore how this method of phenomenal contrast interacts with the sort of content-externalism made familiar by Putnam. I show that the possibility of Twin Earth style cases places important restrictions on the range of properties that the method of phenomenal contrast could plausibly apply to. Moreover, these restrictions would apply to some paradigmatically low-level properties as well as to some of the frequently advanced high-level properties. I also draw some general lessons about the different ways one might conceive of the relation between phenomenal character and representational content. (shrink)

In 2016, this Journal published an article by Rob Lawlor1 on what we might call the acceptance-refusal asymmetry in competence requirements. This is the view that there can be cases in which a patient is sufficiently competent to accept a treatment, but not sufficiently competent to refuse it. Though the main purpose of Lawlor’s paper was to distinguish this asymmetry from various other asymmetries with which it has sometimes been confused,1 Lawlor also presented a brief case in favour of (...) it. Developing an earlier argument of Ian Wilks’,2 3 Lawlor argued that, when the risks associated with refusing a treatment are graver than those associated with accepting it, a higher level of competence may be required to refuse a treatment than to accept it. This claim could have important implications for the law, since determinations of competence often play a central role in determining the lawfulness of refusing or imposing a treatment. Indeed, the acceptance-refusal asymmetry in competence requirements, or something close to it, has played an important role in court judgments.2 However, Lawlor himself suggests that his conclusion will have practical implications only in a narrow range of cases.3 In this issue, Pickering, Giles Newton-Howes and Simon Walker respond to Lawlor’s piece.4 They deny that competence requirements should depend on the level of risk associated with a decision, and thus that there is any basis for the acceptance-refusal asymmetry in competence requirements. Part of the authors’ argument involves contesting the way in which Lawlor uses cases to support his view. In one case cited by Lawlor—and drawn from Wilks—we are invited to consider a whether ….

The present paper proposes an integrative account of social forms of practical irrationality and corresponding disruptions of individual and group-level emotion regulation. I will especially focus on disruptions in emotion regulation by means of collaborative agential and doxastic akrasia. I begin by distinguishing mutual, communal and collaborative forms of akrasia. Such a taxonomy seems all the more needed as, rather surprisingly, in the face of huge philosophical interest in analysing the possibility, structure and mechanisms of individual practical irrationality, with very (...) little exception, there are no comparable accounts of social and collaborative cases. However, I believe that, if it is true that individual akrasia is, in the long run, harmful for those who entertain it, this is even more so in social contexts. I will illustrate this point by drawing on various small group settings, and explore a number of socio-psychological mechanisms underlying collaborative irrationality, in particular groupthink. Specifically, I suggest that in collaborative cases there is what I call a spiralling of practical irrationality at play. I will argue that this is typically correlated and indeed partly due to biases in individual members' affect control and eventually the group's with whom the members identify. (shrink)

Lewis’s Principal Principle says that one should usually align one’s credences with the known chances. In this paper I develop a version of the Principal Principle that deals well with some exceptional cases related to the distinction between metaphysical and epistemic modal­ity. I explain how this principle gives a unified account of the Sleeping Beauty problem and chance-­based principles of anthropic reasoning. In doing so, I defuse the Doomsday Argument that the end of the world is likely to be nigh. (...) GPI Working Paper No. 8-2021. (shrink)

Abstract: We propose a view of vagueness as a semantic property of names and predicates. All entities are crisp, on this semantic view, but there are, for each vague name, multiple portions of reality that are equally good candidates for being its referent, and, for each vague predicate, multiple classes of objects that are equally good candidates for being its extension. We provide a new formulation of these ideas in terms of a theory of granular partitions. We show that this (...) theory provides a general framework within which we can understand the relation between vague terms and concepts and the corresponding crisp portions of reality. We also sketch how it might be possible to formulate within this framework a theory of vagueness which dispenses with the notion of truth-value gaps and other artifacts of more familiar approaches. Central to our approach is the idea that judgments about reality involve in every case (1) a separation of reality into foreground and background of attention and (2) the feature of granularity. On this basis we attempt to show that even vague judgments made in naturally occurring contexts are not marked by truth-value indeterminacy. We distinguish, in addition to crisp granular partitions, also vague partitions, and reference partitions, and we explain the role of the latter in the context of judgments that involve vagueness. We conclude by showing how reference partitions provide an effective means by which judging subjects are able to temper the vagueness of their judgments by means of approximations. (shrink)

On a Parfit-inspired account of culpability, as the psychological connections between a person’s younger self and older self weaken, the older self’s culpability for a wrong committed by the younger self diminishes. Suppose we accept this account and also accept a culpability-based upper limit on punishment severity. On this combination of views, we seem forced to conclude that perpetrators of distant past wrongs should either receive discounted punishments or be exempted from punishment entirely. This article develops a strategy for resisting (...) this conclusion. I propose that, even if the perpetrators of distant past wrongs cannot permissibly be punished for the original wrongs, in typical cases they can permissibly be punished for their ongoing and iterated failures to rectify earlier wrongs. Having set out this proposal, I defend it against three objections, before exploring how much punishment it can justify. (shrink)

We here make preliminary investigations into the model theory of DeMorgan logics. We demonstrate that Łoś's Theorem holds with respect to these logics and make some remarks about standard model-theoretic properties in such contexts. More concretely, as a case study we examine the fate of Cantor's Theorem that the classical theory of dense linear orderings without endpoints is $\aleph_{0}$-categorical, and we show that the taking of ultraproducts commutes with respect to previously established methods of constructing nonclassical structures, namely, Priest's (...) Collapsing Lemma and Dunn's Theorem in 3-Valued Logic. (shrink)

I consider a new, non-disjunctive strategy for ‘relational’ or ‘naïve realist’ theories to respond to arguments from ‘perfect’ (causally matching) hallucinations. The strategy, in a nutshell, is to treat such hypothetical cases as instances of perception rather than hallucination. After clarifying the form and dialectic of such arguments, I consider three objections to the strategy. I provide answers to the first two objections but concede that the third — based on the possibility of ‘chaotic’ (uncaused) perfect hallucinations — cannot obviously (...) be dealt with by the proposed strategy. However, such ‘chaotic’ scenarios are also problematic for standard representational accounts of experience. Thus I conclude that perfect hallucinations pose no more of a threat to the relational theory than to its main representational rival. (shrink)

A probabilistic Chomsky–Schützenberger hierarchy of grammars is introduced and studied, with the aim of understanding the expressive power of generative models. We offer characterizations of the distributions definable at each level of the hierarchy, including probabilistic regular, context-free, (linear) indexed, context-sensitive, and unrestricted grammars, each corresponding to familiar probabilistic machine classes. Special attention is given to distributions on (unary notations for) positive integers. Unlike in the classical case where the "semi-linear" languages all collapse into the regular languages, using analytic (...) tools adapted from the classical setting we show there is no collapse in the probabilistic hierarchy: more distributions become definable at each level. We also address related issues such as closure under probabilistic conditioning. (shrink)

A recent challenge to statist arguments defending the right of states to exclude prospective immigrants maintains that such statist arguments prove too much. Specifically, the challenge argues that statist arguments, insofar as they are correct, entail that states may permissibily exclude current members' newcomers by birth, which seems to violate a widely held intuition that members' newcomers by birth ought automatically to be granted membership rights. The basic claim is that statist arguments cannot account for the differntial treatment between prospective (...) immigrants and newcomers by birth. Call this the newcomer-by-birth objection. This article rejects the newcomer-by-birth rejection. It begins by sketching the precise extent to which the objection applies to statist arguments. It then examines the case of newcomers by birth and argues for a principled basis for treating them differentially from prospective immigrants such that a right to exclude prospective immigrants need not entail a right to exclude newcomers by birth. But this distinction holds only in most cases, not all, and therefore the newcomer-by-birth objection is not entirely defeated. With respect to the cases in which the objection does hold, it is argued that such cases are morally akin to international adoption, and thus morally benign. All considered, statist arguments easily survive the newcomer-by-birth objection. (shrink)

In “The Possibility of Epistemic Nudging” (2021), I address a phenomenon that is widely neglected in the current literature on nudges: intentional doxastic nudging, i.e. people’s intentional influence over other people’s beliefs, rather than over their choices. I argue that, at least in brute cases, nudging is not giving reasons, but rather bypasses reasoning altogether. More specifically, nudging utilizes psychological heuristics and the nudged person’s biases in smart ways. The goal of my paper is to defend the claim that nudging, (...) even when it bypasses reasoning, can result in justified beliefs and knowledge. As I argue, it takes two things to accomplish this goal: suitable meta-epistemological views and appropriate circumstances. If a broadly reliabilist account of justified beliefs and knowledge is correct, and if the relevant belief-forming methods are externally individuated in the right way, then nudging to knowledge is possible. If, in addition, the nudger is knowledgeable, epistemically benevolent and systematically effective, then nudging to knowledge will become reality. In their replies Neil Levy (2021) and Jonathan Matheson and Valerie Joly Chock (2021), put pressure on my argument from different angles. Levy thinks that a better case can be made for his view that nudging is giving testimonial reasons, and finds my objections to this view unconvincing. Matheson and Joly Chock, on the other hand, point out that acquiring knowledge through nudging (i.e. epistemic nudging) is compatible with evidentialism, even if nudging is not giving reasons. On their view, evidentialism provides an explanation of epistemic nudging that is superior to my own account, which, according to them, also suffers from a number of counterintuitive consequences. I am grateful to my critics for raising these concerns, because considering them deepens our perspective on the target phenomenon, and has made me think harder about the relevant epistemological issues. Nevertheless, I am convinced that my core claims can be defended against these criticisms. (shrink)

It is often thought that religious experiences provide support for the cumulative case for the existence of the God of classical monotheism. In this paper, I formulate an Evil-god challenge that invites classical monotheists to explain why, based on evidence from religious experience, the belief in an omnipotent, omniscient, omnibenevolent god is significantly more reasonable than the belief in an omnipotent, omniscient, evil god. I demonstrate that religious experiences substantiate the existence of Evil-god more so than they do the (...) existence of Good-god, and, consequently, that the traditional argument from religious experience fails: it should not be included in the cumulative case for the existence of Good-god.

In this chapter I examine how expected-value theory might inform responses to what I call the dual-use problem. I begin by defining that problem. I then outline a procedure, which invokes expected-value theory, for tackling it. I first illustrate the procedure with the aid of a simplified schematic example of a dual-use problem, and then describe how it might also guide responses to more complex real-world cases. I outline some attractive features of the procedure. Finally, I consider whether and how (...) the procedure might be amended to accommodate various criticisms of it. (shrink)

Barnett provides an interesting new challenge for Dogmatist accounts of perceptual justification. The challenge is that such accounts, by accepting that a perceptual experience can provide a distinctive kind of boost to one’s credences, would lead to a form of diachronic irrationality in cases where one has already learnt in advance that one will have such an experience. I show that this challenge rests on a misleading feature of using the 0–1 interval to express probabilities and show that if we (...) switch to using Odds or Log-Odds, the misleading appearance that there is only ‘a little room’ for one’s credences to increase evaporates. Moreover, there are familiar, independent reasons for taking the Log-Odds scale to provide a clearer picture of the confirmatory effect of evidence. Thus the Dogmatist can after all escape the charge of diachronic irrationality. (shrink)

Birks and Buyx (2018) claim that, at least in the foreseeable future, nonconsensual neurointerventions will almost certainly suppress some valuable mental states and will thereby impose an objectionable harm to mental integrity—a harm that it is pro tanto wrong to impose. Of course, incarceration also interferes with valuable mental states, so might seem to be objectionable in the same way. However, Birks and Buyx block this result by maintaining that the negative mental effects of incarceration are merely foreseen, whereas those (...) of neurointerventions are intended. We dispute Birks and Buyx’s characterization of the descriptive difference between these effects. In both cases, the negative effects are caused, not constituted, by the act in question. (shrink)

When surveying the scholarly literature over Wittgensteinian fideism, it is easy to get the sense that the principal interlocutors, Kai Nielsen and D.Z. Phillips, talk past one another, but finding the right words for appraising the distance between the two voices is difficult. In this paper, I seek to appreciate this intellectual distance through an exploration of the varying philosophical aims of Nielsen and Phillips, of the different intellectual imperatives that guide their respective conceptions of philosophical practice. In so doing, (...) I seek to show how a contemplative mode in philosophy may be used to appraise a philosophical dispute and the terms of disagreement. In this case, a contemplative approach to understanding the dispute would frame Nielsen’s and Phillips’ contributions against the backdrop of the ends they conceive philosophy to have. (shrink)

According to general wisdom, Carnap's quasianalysis is an ingenious but definitively flawed approach to epistemology and philosophy of science. I argue that this assessment is mistaken. Rather, Carnapian quasianalysis can be reconstructed as a special case of a general theory of structural representation. This enables us to exploit some interesting analogies of quasianalysis with the representational theory of measurement. It is shown how Goodman's well-known objections against the quasianalytical approach may be defused in the new framework. As an application, (...) I sketch how the thesis of empirical underdetermination of theories may be elucidated in the framework of quasianalysis. (shrink)

I argue that pain sensations are perceptual states, namely states that represent (actual or potential) damage. I defend this position against the objection that pains, unlike standard perceptual states, do not allow for an appearance-reality distinction by arguing that in the case of pain as well as in standard perceptual experiences, cognitive penetration or malfunctions of the underlying sensory systems can lead to a dissociation between the sensation on the one hand, and what is represented on the other hand. (...) Moreover, I refute the objection that the allegedly weak correlation between pain and bodily damage forces intentionalist accounts of pain to postulate so many malfunctions (misrepresentations respectively) that such accounts become implausible. I also rebut Murat Aydede’s objection that our linguistic practice supposedly shows that there is a conceptual difference between standard perceptual experiences and pain sensations by challenging Aydede’s premise that we always withdraw standard perceptual reports in case of counterevidence, while we never do that with pain reports. At the end, I propose an explanation as to why we do not express perceptual reports of (potential) bodily damage in objectivist, but in mental terms. (shrink)
