The apparent contextual variability exhibited by ‘knows’ and its cognates—brought to attention in examples like Keith DeRose’s Bank Case—poses familiar problems for conservative forms of invariantism about ‘knows’. The paper examines and criticises a popular response to those problems, one that involves appeal to so-called ‘pragmatic’ features of language. It is first argued, contrary to what seems to have been generally assumed, that any pragmatic defence faces serious problems with regard to our judgments about retraction. Second, the familiar objection that (...) the pragmatic effects at issue do not seem to be cancellable is considered. Advocates of the pragmatic defence have suggested that cancellability concerns can be dealt with fairly readily. It is shown both that their recent attempts to respond to those concerns, and some other possible attempts, are unsuccessful. Finally, it is argued that the popular relevance-based accounts, found in the work of Jessica Brown, Alan Hazlett, and Patrick Rysiew, fail to provide a satisfactory explanation of our judgments.

A powerful objection to subject-sensitive invariantism concerns various ‘strange-but-true’ conditionals. One popular response to this objection is to argue that strange-but-true conditionals pose a problem for non-sceptical epistemological theories in general. In the present paper, it is argued that strange-but-true conditionals are not a problem for contextualism about ‘know’. This observation undercuts the proposed defence of SSI, and supplies a surprising new argument for contextualism.

The late 1980s and early 1990s saw the rise of contextualist theories of knowledge ascriptions. Contextualists about ‘knows’ maintain that utterances of the form ‘S knows p’ and ‘S doesn’t know p’ resemble utterances such as ‘Peter is here’ and ‘Peter is not here’, in the sense that their truth-conditions vary depending upon features of the context in which they are uttered. In recent years, contextualism about ‘knows’ has come under heavy attack. This has been associated with a proliferation of (...) defences of so-called invariantist accounts of knowledge ascriptions, which stand united in their rejection of contextualism. The central goal of the present work is two-fold. In the first instance, it is to bring out the serious pitfalls in many of those recent defences of invariantism. In the second instance, it is to establish that the most plausible form of invariantism is one that is sceptical in character. Of course, the prevailing preference in epistemology is for non- sceptical accounts. The central conclusions of the thesis might therefore be taken to show that – despite recent attacks on its plausibility – some form of contextualism about ‘knows’ must be correct. However, this project is not undertaken without at least the suspicion that embracing sceptical invariantism is to be preferred to embracing contextualism. In the course of the discussion, I therefore not only attempt to rebut some standard objections to sceptical invariantism, but also to reveal – in at least a preliminary way – how the sceptical invariantist might best argue for the superiority of her account to that of the contextualist.

Changes in conversationally salient error possibilities, and/or changes in stakes, appear to generate shifts in our judgments regarding the correct application of ‘know’. One prominent response to these shifts is to argue that they arise due to shifts in belief and do not pose a problem for traditional semantic or metaphysical accounts of knowledge. Such doxastic proposals face familiar difficulties with cases where knowledge is ascribed to subjects in different practical or conversational situations from the speaker. Jennifer Nagel has recently (...) offered an ingenious response to these problematic cases—appeal to egocentric bias. Appeal to this kind of bias also has the potential for interesting application in other philosophical arenas, including discussions of epistemic modals. In this paper, I draw on relevant empirical literature to clarify the nature of egocentric bias as it manifests in children and adults, and argue that appeal to egocentric bias is ill-suited to respond to the problem cases for doxastic accounts. Our discussion also has significant impact on the prospects for application of egocentric bias in other arenas. (shrink)

This paper critically assesses Sosa’s normative framework for performances as well as its application to epistemology. We first develop a problem for one of Sosa’s central theses in the general theory of performance normativity according to which performances attain fully desirable status if and only if they are fully apt. More specifically, we argue that given Sosa’s account of full aptness according to which a performance is fully apt only if safe from failure, this thesis can’t be true. We then (...) embark on a rescue mission on behalf of Sosa and work towards a weakened account of full aptness. The key idea is to countenance a distinction between negligible and non-negligible types of risk and to develop an account of full aptness according to which even performances that are endangered by risk can be fully apt, so long as the risk is of a negligible type. While this alternative account of full aptness solves the problem we developed for Sosa earlier on, there is also bad news for Sosa. When applied to epistemology, the envisaged treatment of barn façade cases as cases in which the agent falls short of fully apt belief will no longer work. We show that, as a result, Sosa faces a new version of a familiar dilemma for virtue epistemology. Either he construes full aptness as strong enough to get barn façade cases right in which case his view will run right into the problem we develop. Or else he construes full aptness as weak enough to avoid this problem but then he will not be able to deal with barn façade cases in the way envisaged. (shrink)

The relation of normic support offers a novel solution to the proof paradox: a paradox in evidence law arising from legal cases involving merely statistical evidence (Smith 2018). Central to the normic support solution has been the thesis that merely statistical evidence cannot confer normic support. However, it has been observed that there are exceptions to this: there exist cases where merely statistical evidence can give rise to normic support (Blome-Tillmann 2020). If correct, this fact seems to undermine the normic (...) support solution to the proof paradox. This paper explores a resolution: normic support can resolve the proof paradox even though merely statistical evidence sometimes gives rise to normic support. The key to understanding this resolution lies with a source of evidential support that arises out of bodies of evidence that involve *character evidence* (Colyvan, et al. 2001). It turns out that character evidence can provide normic support when it is grounded in our knowledge of a certain kind of disposition individuals can have: *goal-directed dispositions*. The upshot is the recovery of the normic support solution to the puzzle of whether statistical evidence can meet legal standards of proof. (shrink)

The increasing use of Generative AI raises many ethical, philosophical, and legal issues. A key issue here is uncertainties about how different degrees of Generative AI assistance in the production of text impacts assessments of the human authorship of that text. To explore this issue, we developed an experimental mixed methods survey study (N = 602) asking participants to reflect on a scenario of a human author receiving assistance to write a short novel as part of a 3 (high, medium, (...) or low degrees of assistance) X 2 (human or AI assistant) factorial design. We found that, for a human author, the degree of assistance they receive matters for our assessments of their level of authorship, creatorship, and responsibility, but not what or who rendered that assistance, although it was more important to disclose human rather than AI assistance. However, in our assessments of the assisting agent, human assistants were viewed as warranting higher rates of authorship, creatorship, and responsibility, compared to AI assistants rendering the same level of support. These results help us to better understand emerging norms around collaborative human-AI generated text, with implications for other types of collaborative content creation. (shrink)

Cette contribution examine la pertinence de la Convention européenne des droits de l’homme pour les personnes en situation de handicap. Elle se penche sur les principes de la Convention tels que la dignité humaine, l’autonomie personnelle et l’égalité, qui sont particulièrement importants pour les personnes en situation de vulnérabilité. Le texte aborde ensuite les obligations négatives et positives de l’État à l’égard des personnes handicapées. En ce qui concerne les premières, le texte souligne la nécessité de procéder à des évaluations (...) individualisées dans le cadre des processus décisionnels et de trouver un équilibre entre les droits des personnes et les intérêts de l’État. En ce qui concerne les secondes, l’État est également tenu d’évaluer les besoins réels des personnes handicapées. Il doit fournir une aide suffisante, tout en pouvant prendre en compte des considérations financières légitimes. La Convention européenne est ensuite examinée dans sa relation avec la Convention des Nations Unies relative aux droits des personnes handicapées. La Cour européenne des droits de l’homme s’efforce généralement d’interpréter la Convention européenne en harmonie avec les autres traités internationaux. Si la Convention des Nations Unies a ainsi influencé certains développements dans la jurisprudence de la Cour, il existe également des cas où la Cour a estimé que la Convention européenne n’offrait pas le même niveau de protection que la Convention des Nations Unies. La relation entre les deux conventions reste dynamique, ce qui laisse penser qu’avec le temps, davantage de principes de la Convention des Nations Unies pourraient devenir partie intégrante de l’interprétation de la Convention européenne.

The authors argue that the time is ripe for national and corporate leaders to move consciously towards the development of global ethics. This papers presents a model of global ethics, a rationale for the development of global ethics, and the implications of the model for research and practice.

In Part I of this paper, we identified and compared various schemes for trivalent truth conditions for indicative conditionals, most notably the proposals by de Finetti and Reichenbach on the one hand, and by Cooper and Cantwell on the other. Here we provide the proof theory for the resulting logics DF/TT and CC/TT, using tableau calculi and sequent calculi, and proving soundness and completeness results. Then we turn to the algebraic semantics, where both logics have substantive limitations: DF/TT allows for (...) algebraic completeness, but not for the construction of a canonical model, while CC/TT fails the construction of a Lindenbaum-Tarski algebra. With these results in mind, we draw up the balance and sketch future research projects. (shrink)

Does it make sense to say that certain evaluative outlooks and political ideologies are essentially negative or oppositional in structure? Intuitively, it seems so: there is a difference between outlooks and ideologies that are expressive of hatred, resentment, and contempt, on the one hand, and those expressive of more affirmative emotions. But drawing this distinction is more difficult than it seems. It requires that we find a way of maintaining the following claim, which I call Negative Orientation: although you claim (...) to value X, you are more accurately described as disvaluing Y. I argue that we cannot make sense of Negative Orientation at the level of evaluative judgments, for nothing about the etiology, content, or justification of evaluative judgments will support the Negative Orientation claim. But we can make sense of it by attending to the psychology of valuing. Using spiteful hatred as a paradigm case, I explain how certain outlooks and ideologies induce and sustain spiteful hatred in their adherents and thereby render the Negative Orientation claim true.

Philosophers and ethicists debate this controversial moral principle illustrating its application to current moral dilemmas such as war, suicide, nuclear power, affirmative action, and morphine use for terminal cancer patients.

Franklin G. Miller and colleagues have stimulated renewed interest in research ethics through their work criticizing clinical equipoise. Over three years and some twenty articles, they have also worked to articulate a positive alternative view on norms governing the conduct of clinical research. Shared presuppositions underlie the positive and critical dimensions of Miller and colleagues' work. However, recognizing that constructive contributions to the field ought to enjoy priority, we presently scrutinize the constructive dimension of their work. We argue that it (...) is wanting in several respects. (shrink)

To several critics of the philosophical method of cases—Robert Cummins, Jonathan Weinberg and his colleagues, and Avner Baz—the fact that philosophical intuitions cannot be calibrated means that we cannot rule out the skeptical hypothesis that the outcome of our theorizing based on these intuitions is deeply distorted by our cognitive artifacts. Moreover, they take this hypothesis to license the negative conclusion that we are unable to have much of the armchair knowledge we typically attribute to ourselves when philosophizing based on (...) appeal to philosophical intuitions. This paper addresses this skeptical argument and shows how this negative conclusion can be resisted. (shrink)

We present a variety of (ω 1 ,∞)-distributive forcings which when applied to models of Martin's Maximum separate certain well known reflection principles. In particular, we do this for the reflection principles SR, SR α (α ≤ ω 1 ), and SRP.

Descartes has a Clarity First epistemology: (i) Clarity is a primitive (indefinable) phenomenal quality: the appearance of truth. (ii) Clarity is prior to other qualities: obscurity, confusion, distinctness – are defined in terms of clarity; epistemic goods – reason to assent, rational inclination to assent, reliability, and knowledge – are explained by clarity. (This is the first of two companion entries; the sequel is called, "Descartes's Method for Achieving Knowledge.").

This essay re-examines Adam Smith’s encounter with Jean-Jacques Rousseau. Against the grain of present scholarship it contends that when Smith read and reviewed Rousseau’s Second Discourse, he neither registered it as a particularly important challenge, nor was especially influenced by, or subsequently preoccupied with responding to, Rousseau. The case for this is made by examining the British context of Smith’s own intervention in his 1759 Theory of Moral Sentiments, where a proper appreciation of the roles of David Hume and Bernard (...) Mandeville in the formation of Smith’s thought pushes Rousseau firmly into the background. Realising this, however, forces us to re-consider our evaluations of Rousseau’s and Smith’s very different political visions. Given that questions of individual recognition, economic inequality, and political stability remain at the heart of today’s social challenges, the implications of this are not just historical but of direct contemporary import.

This book explores the role of divine severity in the character and wisdom of God, and the flux and difficulties of human life in relation to divine salvation. Much has been written on problems of evil, but the matter of divine severity has received relatively little attention. Paul K. Moser discusses the function of philosophy, evidence and miracles in approaching God. He argues that if God's aim is to extend without coercion His lasting life to humans, then commitment to (...) that goal could manifest itself in making human life severe, for the sake of encouraging humans to enter into that cooperative good life. In this scenario, divine agapē is conferred as free gift, but the human reception of it includes stress and struggle in the face of conflicting powers and priorities. Moser's work will be of great interest to students of the philosophy of religion, and theology. (shrink)

Causal decision theory attends to probabilities used to obtain an option's expected utility but for completeness should also attend to utilities of possible outcomes. A suitable formula for an option's expected utility uses a certain type of conditional utility.

Champions of the methodological movement of experimental philosophy have challenged the long-standing practice of relying on intuitive verdicts on cases in philosophical inquiry. They argue that th...

In their highly topical paper, Grahamet alargued that Trusted Research Environments (TREs) are not actually about trust because they reduce or remove ‘…the need for trust in the use and sharing of patient health data’. We believe this is fundamentally mistaken. TREs mitigate or remove some risks, but they do not address all public concerns. In this regard, TREs provide evidence for people to decide whether the bodies holding and using their data can be trusted. TREs may make it easier (...) for people to trust but there is still a need for that trust. (shrink)

Let me start with an example. Presumably our understanding of the sentence ‘dogs bark’ arises somehow from our understanding of its components and our appreciation of how they are combined. That is to say, ‘dogs bark’ somehow gets its meaning from the meanings of the two words ‘dog’ and ‘bark’, from the meaning of the generalization schema ‘ns v’, and from the fact that the sentence results from placing those words in that schema in a certain order. However, as Davidson (...) was the first to emphasize, it is not possible to produce a strict logical deduction of what ‘dogs bark’ means from these more basic facts alone. So a question arises as to which further premises are required. What assumptions about the character of meaning should be added in order to obtain an explanation of the meaning of the sentence on the basis of the meanings of its words? (shrink)

The paper offers a matrix-based logic (relevant matrix quantum physics) for propositions which seems suitable as an underlying logic for empirical sciences and especially for quantum physics. This logic is motivated by two criteria which serve to clean derivations of classical logic from superfluous redundancies and uninformative complexities. It distinguishes those valid derivations (inferences) of classical logic which contain superfluous redundancies and complexities and are in this sense from those which are or in the sense of allowing only the most (...) informative consequences in the derivations. The latter derivations are strictly valid in RMQ, whereas the former are only materially valid. RMQ is a decidable matrix calculus which possesses a semantics and has the finite model property. It is shown in the paper how RMQ by its strictly valid derivations can avoid the difficulties with commensurability, distributivity, and Bell's inequalities when it is applied to quantum physics.

Proposed derivations of the Born rule for Everettian theory are controversial. I argue that they are unnecessary but may provide justification for a simplified version of the Principal Principle. It’s also unnecessary to replace Everett’s idea that a subject splits in measurement contexts with the idea that subjects have linear histories which partition Many worlds? Everett, quantum theory, and reality, Oxford University Press, Oxford, pp 181–205, 2010; Wallace in The emergent multiverse, Oxford University Press, Oxford, 2012, Chapter 7; Wilson in (...) Br J Philos Sci 64:709–737, 2013; The nature of contingency: quantum physics as modal realism, Oxford University Press, Oxford, forthcoming). Linear histories were introduced to provide a concept of pre-measurement uncertainty and I explain why pre-measurement uncertainty for splitting subjects is after all coherent, though not necessary because Everett’s original fission interpretation of branching can arguably be rendered coherent without it, via reference to Vaidman, Tappenden, Sebens and Carroll and McQueen and Vaidman. A deterministic and probabilistic quantum mechanics can be made intelligible by replacing the standard collapse postulate with a no-collapse postulate which identifies objective probability with relative branch weight, supplemented by the simplified Principal Principle and some revisionary metaphysics.

Sainsbury argued that exact extensions for predicates entails the unacceptable infinite tower of higher order vagueness so that exact extensions must be rejected. I offer a second argument: The exact extensions arise when semantic values are assumed to be (exact) properties. But no assignment of unique properties to predicates could arise from any real-world finite basis. How, then, is talk of properties as semantic values to be understood? We distinguish the precise compositional rules of semantics from the operation of messy, (...) imprecise rules at the word/world interface for applicability of minimal predicates. When such application is sufficiently clear it is idealized as property instantiation and semantic composition proceeds in familiar ways. These imprecise rules for application of minimal predicates provide the proper locus for study of vagueness. The conclusions thus far apply to show that higher order vagueness is not forced and that classical logic can generally be retained. I discuss implications for the sorites paradox. Abandoning properties entails abandoning simple correspondence truth understood as Pa is true just in case a has the property signified by P. As an alternative I outline a pragmatist approach to truth, the spirit of which is conveyed by the slogan, “To be true enough is to work well enough.”. (shrink)

Gilbertson, Savulescu, Oakley and Wilkinson propose extending the availability of terminal sedation (TS) to patients with intractable pain and/or suffering who are expected to live more than 2 weeks (hence the designation of extended TS (ETS)) and to patients whose values are known but who do not have decision-making capacity.1 Their plan is worthy of serious consideration: it is, after all, based on the fundamental and well-recognised medical ethical values of patient autonomy and beneficence. But, even when restricted to jurisdictions (...) that allow assisted dying, the ETS proposal raises three important issues. When the authors speak of ‘assisted dying’ and of ‘Voluntary Assisted Dying (VAS)’, they refer specifically to the laws in Australia and similar ones in New Zealand, the Netherlands, Belgium, Luxembourg, Switzerland, Spain and Canada that permit clinicians either to provide patients with lethal medications for self-administration (formerly called physician-assisted suicide) or to administer lethal medications themselves (voluntary euthanasia). First, the authors distinguish—as do many patients and the public—between sedation to unconsciousness and death. Indeed, as the authors point out, the difference seems obvious: unconsciousness can be reversed, death cannot. Yet in the case of TS, this may be …. (shrink)

Data on birth order and parent-offspring relations for 1,601 adolescents participating in the National Longitudinal Study of Adolescent Health were used to test hypotheses about the role of adolescent suicidal behavior in parent-offspring conflict. Among adolescents highly dissatisfied with their mothers, the odds that middleborns would make at least one suicide attempt was 23% that of first- and lastborns (p<.001), but their odds of receiving medical treatment for their attempts was 8.5 times greater than the odds for first- and lastborns (...) (p=.032). The results are tentatively interpreted as supporting the hypothesis that adolescents use suicide attempts to leverage investment from their parents. (shrink)

Ethnophilosophy is widely regarded as a disreputable orientation in African philosophy. For example, critics of ethnophilosophy think of it as a ‘defective philosophy’, a ‘semi-anthropological paraphrase’, a merely ‘implicit philosophy ’, a ‘crazed language’ and so on. Although these negative portrayals were made in the 1980s and 1990s (roughly, 1981–1997), and some of these critics softened their position with time, they persist in the thoughts of some contemporary African philosophers. This is visible in the rather inarticulate unease about ethnophilosophy in (...) many quarters today, witnessed in the characteristic disposition of some African philosophers to distance themselves from the works of Placide Tempels, John S. Mbiti, Léopold Sédar Senghor and Alexis Kagame, and in the talk of a post-ethnophilosophy among some contemporary African philosophers rooted in the belief about the inadequacy of ethnophilosophy. Call those who today still think of ethnophilosophy in this fashion the ethnophilosophy holdouts. The aim of this paper is to give reasons to think that the position of the ethnophilosophy holdouts is not tenable. More positively, I defend a thesis that makes a claim about the positive status of ethnophilosophy as a philosophical orientation. (shrink)

Peter Vanderschraaf’s Strategic Justice is a powerful elaboration and defense of what he calls ‘justice as mutual advantage’. Vanderschraaf opens Strategic Justice by observing that ‘Plato set a template for all future philosophers by raising two interrelated questions: (1) What precisely is justice? (2) Why should one be just?’. He answers that (1) justice consists of conventions which (2) are followed because each sees that doing so is in her interest. These answers depend upon two conditions which Vanderschraaf calls Baseline (...) Consistency and Negative Mutual Expectations. I contend that the plausibility of the first condition depends upon principles which are prior to Vanderchraaf’s conventions of justice and that the second condition does not account for the interest Vanderschraaf must think we take in those principles. I therefore worry that Vanderschraaf does what he accuses other theorists of justice as mutual advantage of doing: going outside the bounds of justice as mutual advantage. To lay the groundwork for his conditions, Vanderschraaf analyzes the circumstances of justice. I argue that, his claims to the contrary notwithstanding, he does not take the circumstances to be the kind of conditions Hume takes them to be, but that he has good reason to do so. (shrink)

During the last ten years John Beatty, Elisabeth Lloyd and I have argued that the semantic conception of theories is, in the context of biological theorizing, a richer conception of theory structure than the syntactic ("received view") conception. Specifically, I have argued semantic conception of theory structure better represents the structure of evolutionary theory and the relationship of this theory to phenomena. One aspect of the semantic conception that is in need of greater attention is the nature of explanation on (...) this conception. In this paper, I argue that the semantic conception provides a richer mo accurate account of scientific explanation, in particular, of evolutionary explanations. In essence, I argue that explanation involves an appeal to numerous theories in addition to the putative explanatory theory. Employment of these theories is not formally possible in a syntactic conception but is in a semantic conception. (shrink)
