Suppose we consider knowledge to be valuable because of the role known propositions play in practical reasoning. This, I argue, does not provide a reason to think that knowledge is valuable in itself. Rather, it provides a reason to think that true belief is valuable from one standpoint, and that justified belief is valuable from another standpoint, and similarly for other epistemic concepts. The value of the concept of knowledge is that it provides an economical way of talking about many (...) epistemic concepts that are valuable in itself from one standpoint or another. In this way knowledge is like a Swiss Army Knife; a Swiss Army Knife is not useful as such on any occasion, but it provides an efficient way of carrying around different tools that are useful in themselves on different occasions.

It has been claimed that justification, conceived traditionally in an internalist fashion, is not an epistemologically important property. I argue for the importance of a conception of justification that is completely dependent on the subject’s experience, using an analogy to advice. The epistemological importance of a property depends on two desiderata: the extent to which it guarantees the epistemic goal of attaining truth and avoiding falsehood, and the extent to which it depends only on the information available to the believer. (...) The traditional intermalist notion of justification completely satisfies the second desideratum and largely satisfies the first. (shrink)

John N. Williams (1994) and Matthew Weiner (2005) invoke predictions in order to undermine the normative relevance of knowledge for assertions; in particular, Weiner argues, predictions are important counterexamples to the Knowledge Account of Assertion (KAA). I argue here that they are not true counterexamples at all, a point that can be agreed upon even by those who reject KAA.

I propose that testimony is subject to a norm that is backed by a credibility sanction: whenever the norm is violated, it is appropriate for the testifier to lose some credibility for their future testimony. This is one of a family of sanction-based norms, where violation of the norm makes it appropriate to lose some power; in this case, the power to induce belief through testimony. The applicability of the credibility norm to testimony follows from the epistemology of testimony, in (...) that false or unjustified testimony weakens the reason for belief that is provided by the speaker's future testimony.

I argue that there is a wide variety of epistemic norms, distributed along two different spectra. One spectrum runs from the ideal to the practical and concerns the extent to which it is possible to follow the norm given our cognitive and epistemic limitations. The other spectrum runs from thin to thick and concerns the extent to which the norm concerns facts about our beliefs over and above the content of the belief. Many putative epistemic norms, such as truth and (...) various conceptions of justification, can be found at different points on the spectra. There is no single obvious privileged point from which to say any of these norms is more fundamental than the others, though there may be some reason to doubt that some of the norms are intrinsically interesting.

I argue that ⌜p or q⌝ can be interpreted as (p ∨ q) ∧ ♢p ∧ ♢q, where ♢ is a possibility modal whose flavor can be epistemic, circumstantial, or deontic. I show that no extant theory can account for this generalization, and argue that the best way to do so is with a direct theory on which ‘or’ means λp.λq.(p∨q)∧♢p∧♢q. I show that the resulting theory also yields an appealing account of both wide- and narrow-scope free choice inferences.

‘Reasonable wrongdoers’ reasonably, but wrongly, take themselves to act permissibly. Many responsibility theorists assume that since we cannot reasonably expect these wrongdoers to behave differently, they are not blameworthy. These theorists impose a Reasonable Expectation Condition on blame. I argue that reasonable wrongdoers may be blameworthy. It is true that we often excuse reasonable wrongdoers, but sometimes this is because we do not regard their behavior as objectionable in a way that makes blame appropriate. As such, these cases do not (...) support the proposition that wrongdoers are excused just because they reasonably take themselves to act permissibly. For the relevant support, we should consider cases in which a reasonable wrongdoer’s behavior is unambiguously objectionable by our moral lights. But here again we fail to find decisive support for the Reasonable Expectation Condition since it is not obvious—independent of a prior commitment to this condition—that such wrongdoers are not blameworthy. After laying out the above argument, as well as offering a positive account of why reasonable wrongdoers are sometimes blameworthy, I turn to consider objections. The most important of these is that it is simply unfair to blame those who reasonably take themselves to behave unobjectionably and who cannot be expected to behave otherwise. (shrink)

The recent emergence of machine-manipulated media raises an important societal question: How can we know whether a video that we watch is real or fake? In two online studies with 15,016 participants, we present authentic videos and deepfakes and ask participants to identify which is which. We compare the performance of ordinary human observers with the leading computer vision deepfake detection model and find them similarly accurate, while making different kinds of mistakes. Together, participants with access to the model’s prediction (...) are more accurate than either alone, but inaccurate model predictions often decrease participants’ accuracy. To probe the relative strengths and weaknesses of humans and machines as detectors of deepfakes, we examine human and machine performance across video-level features, and we evaluate the impact of preregistered randomized interventions on deepfake detection. We find that manipulations designed to disrupt visual processing of faces hinder human participants’ performance while mostly not affecting the model’s performance, suggesting a role for specialized cognitive capacities in explaining human deepfake detection performance. -/- .

Amid the many figures who number among the Thomists writing during the early 20th century period of revival in scholastic thought in the Roman Catholic Church in the wake of the encyclical letter Aeterni Patris (1879) of Leo XIII, there is numbered the French convert, Jacques Maritain (1882–1973). Over the course of his long lifetime, Maritain authored works covering a host of philosophical and theological topics: epistemology, the philosophy of the sciences and natural philosophy, aesthetics, moral philosophy, political philosophy, metaphysics, (...) the philosophy of history, etc. The details concerning Maritain’s youth and conversion have been ably told by others and can be consulted by the interested reader. Detailed bibliographies of his works are available for those interested in engaging the full breadth of his writing. In this article, I will focus on the particular shape of Maritain’s Thomism and his place in the overall hermeneutics of the Thomistic tradition, in particular the debt that he owes to John Poinsot (1589–1644), to whom he refers as “John of St. Thomas,” in accord with the standard appellations within the Thomistic tradition in which he wrote. Following a general account of Maritain’s “style” of Thomism, I will provide a specific catalogue of some central themes in his thought that bear the clear impress of his engagement with the thought of John of St. Thomas. Without claiming to be exhaustive, this article intends to provide the reader with a sufficient appraisal of the main lines of influence exercised upon Maritain’s thought by the Baroque Commentator, without whose philosophical and theological works Maritain’s own labors would be unthinkable.

What sort of philosophical work are natural kinds suited for? Scientific realists often contend that they provide the ‘aboutness’ of successful of scientific classification and explain their epistemic utility (among other side hustles). Recent history has revealed this to be a tricky job — particularly given the present naturalistic climate of philosophy of science. As a result, we’ve seen an explosion of different sorts of theories. This phenomenon that has suggested to some that philosophical theorizing about natural kinds has reached (...) a sort of ‘scholastic twilight’ and that the concept (or family of concepts) has outlived its utility: perhaps there’s no work natural kinds are suited for. While I think this pessimistic take is unwarranted, I will argue that it is worth rethinking the roles to which a reasonably naturalistic account of natural kinds can be fruitfully put. Natural kinds deserve a shorter work week. (shrink)

This article argues that Dewey expresses what seems to be a core enactive commitment to constructivism: that creatures do not encounter pre-existing realities but bring them out by altering their surroundings. He adds that constructivism does not obviate realism because changes, once introduced, really are there in relation to a creature’s capacities. This poses a dilemma. If enaction primarily entails altering the external milieu, then the movement repeats pragmatism, also collapsing a basis upon which many of its authors differentiate their (...) outlooks from ecological psychology’s realism. Yet if constructive activity is largely interior, as enactivists’ language sometimes suggests, then critics may be right in saying that the movement backslides into early Modern solipsism. A broader argument is that enactivists sometimes perpetuate what James characterizes as monistic halfway empiricism. Here, the risk is that researchers hold positions not because of evidence but regardless of it, or stipulate terminological definitions that exclude opposing views ahead of time. Even physics remains ununified, and there may be room for combining antagonistic accounts of mind. Or maybe normally hostile positions like enactivism and functionalism are, with some terminological reframing, reconcilable. The article also touches on historical points, such as the fact that American philosophy and enactivism have Asian and evolutionary influences, or that they react against common schools. The purpose is to clarify the movements in question and identify where enactivists engage in something like halfway empiricism by orienting themselves against enemies based more in fiction than fact.

This article examines epistemic impacts of social media, merging Gibson’s affordance theory with the notion of selective permeability, which holds people encounter objective differences in a setting because of their distinct capacities, only here applying the idea to online spaces. I start by circumscribing my deployment of “affordances,” taking care not to totally divorce the term from Gibson’s intent, as often happens in information technologies research. I next detail ways that selective permeability characterizes online epistemic landscapes, focusing on how factors (...) (like culture) moderate normative standards for sharing information. This leads to a discussion about selective receptivity and blindness to information in the context of social media—a situation that amplifies political divides and renders antagonists mutually incomprehensible. This segues into my final topic: an exposition of how social media can make the offline world more selectively hostile to some. An additional proposition is that practical habits cultivated on networking apps can modulate what affordances are present in offline arenas, as opposed to just affecting which ones get noticed. Throughout, I suggest that selective permeability answers an increasingly recognized challenge: the difficulty of generalizing conclusions about one app to others and across cultures, ages, etc. Ultimately, my aim is not only to explicate how social media fragments common social knowledge but to defend selective permeability as an epistemic template for comprehending social media.

In recent years, multiple authors have voiced discontent with the theoretical and practical neglect of the concept of ability. This includes, but is not limited to, philosophers of disability who have long assailed the implausible accounts of ability utilized by most social and political philosophers. Historically, most philosophers took it for granted that the meaning of ability will come easily, or is even a given, when higher-order questions are addressed. The aim of this chapter is to animate discussions about ability (...) trouble, which is to say, to animate (i) concern over the lack of philosophical inquiry that takes the concept of ability seriously as a problem in its own right and to animate (ii) novel interest in and further research on the concept of ability—and, correlatively, disability. We first analyze a famous argument concerning moral status that exemplifies how treating the concept of ability as a mere matter of common sense can lead philosophical inquiry awry. We then turn to the role of the concept of ability in an account that does, at least prima facie, take the concept seriously: Sen and Nussbaum’s capabilities approach. While better than common-sense approaches, we draw a cautionary tale, suggesting that even there the concept is simplified in theoretically and practically problematic ways. We conclude with a number of open questions offered in the hope of inspiring future non-ideal research on the topic. (shrink)

Implicit in much of the recent literature on conceptual engineering and conceptual ethics is the assumption that when speakers argue that we should talk or think about a concept in a specific way, they are doing so as inquirers—as speakers who are invested in arriving at the correct or best view of this concept. In this paper I question that assumption and argue that philosophers have been too quick to project idealized versions of themselves into the contexts of conceptual articulation (...) and conceptual dispute. Speakers often engage in this activity to further interests of theirs that have nothing to do with inquiry, instead carrying out what I call ‘conceptual domination’. Speakers are engaged in conceptual domination when they aim to bring about and enforce widespread uptake for a view of a concept by exploiting institutions and institutional authority. They do so because this view best serves interests that are either irrelevant to or actively interfere with inquiry concerning this concept—paradigmatically their material interests. I consider sources of evidence for assessing whether speakers are engaging in conceptual domination, analyze two case studies, and consider how to push back against conceptual dominators. (shrink)

This paper seeks to show how MacIntyre’s concept of a practice can survive a series of ‘scope problems’ which threaten to render the concept inapplicable to business ethics. I begin by outlining MacIntyre’s concept of a practice before arguing that, despite an asymmetry between productive and non-productive practices, the elasticity of the concept of a practice allows us to accommodate productive and profitable activities. This elasticity of practices allows us to sidestep the problem of adjudicating between practitioners and non-practitioners as (...) well as the problem of generic activities. I conclude by suggesting that the contemporary tendency to regard work as an object of consumption, rather than undermining MacIntyre’s account of practices, serves to demonstrate the potential breadth of its applicability.

Philosophers have long been interested in a series of interrelated questions about natural kinds. What are they? What role do they play in science and metaphysics? How do they contribute to our epistemic projects? What categories count as natural kinds? And so on. Owing, perhaps, to different starting points and emphases, we now have at hand a variety of conceptions of natural kinds—some apparently better suited than others to accommodate a particular sort of inquiry. Even if coherent, this situation isn’t (...) ideal. My goal in this article is to begin to articulate a more general account of ‘natural kind phenomena’. While I do not claim that this account should satisfy everyone—it is built around a certain conception of the epistemic role of kinds and has an obvious pragmatic flavour—I believe that it has the resources to go further than extant alternatives, in particular the homeostatic property cluster view of kinds.

The self-indication assumption (SIA) claims that given that one exists, one should think that the universe has many people, for a universe that has more people is more likely to contain any particular person. SIA is attractive to many because it diffuses the infamous doomsday argument, and avoids the problems of its main rival, the self-sampling assumption (SSA), which instructs one to reason as if they’re randomly selected from the people in their reference class. Here, I will go further than (...) the traditional argument for SIA from its ability to avoid the doomsday argument: I will show that any view other than SIA must accept the soundness of the doomsday argument and certain even stranger conclusions. Additionally, I’ll argue that the main objection to SIA, the presumptuous philosopher case, is unconvincing. Together then, these considerations give one a strong reason to adopt SIA. (shrink)

Pessimists sometimes declare that death makes everything we do pointless or meaningless. In this essay, I consider the motivations for this worry about our collective mortality. I then examine some common responses to this worry that emphasize moderating our standards or changing our goals. Given some limitations of the “moderating our standards” response, I suggest that Viktor Frankl’s view about the permanence of the past offers a different and perhaps better way of responding to the worry that death renders our (...) lives meaningless. After outlining his view, its implications, and the view of time it assumes, I consider and respond to some possible objections to Frankl’s view. If Frankl is right, death cannot make life meaningless or pointless because meaning is attained within life, and when we die our completed lives endure as part of the past. (shrink)

It is now widely expected that climate change will be serious enough that a very large number of people will be displaced from their homes because of events relating to or resulting from climate change. Such events may include rising sea levels (and resulting increased salination of ground water), stronger hurricanes and tropical storms, drought, floods, increased and more intense wildfires, and other extreme or (previously) unusual weather events. Although estimates vary widely, it seems very likely that many millions of (...) people—perhaps hundreds of millions if sufficient precautions are not taken—will be forced from their homes by these events related to climate change. In the public imagination, much of the attention has been on ‘climate refugees’, where this is taken to mean people who have crossed borders. However, there is good reason to believe that a very large percentage—probably a significant majority—of displacement resulting from climate change will be, or could be, internal. In this chapter I argue that there are likely to be a large number of cases where internal displacement related to climate change is of international concern, and where, therefore, states have significant moral reasons to provide assistance, either directly to those displaced, or else to the state in which the displacement has taken place. My claim is that internal displacement arising from climate change is of international concern and so grounds a duty of aid by states able to provide it, when this displacement threatens the basic human rights of those displaced, and when the local or domestic government cannot or will not take the necessary steps to meet the needs and protect the rights of those who are displaced.

Recent work has argued that belief is weak: the level of rational credence required for belief is relatively low. That literature has contrasted belief with assertion, arguing that the latter requires an epistemic state much stronger than (weak) belief---perhaps knowledge or even certainty. We argue that this is wrong: assertion is just as weak as belief. We first present a variety of new arguments for this, and then show that the standard arguments for stronger norms are not convincing. Finally, we (...) sketch an alternative picture on which the fundamental norm of assertion is to say what you believe, but both belief and assertion are weak. To help make sense of this, we propose that both belief and assertion involve navigating a tradeoff between accuracy and informativity, and so it can makes sense to believe/say something you only have weak evidence for, if it is informative enough.

I argue that the Bradley of the 1883 The Principles of Logic marks and separates contents under tension in judgments. The separation comes in attending to content as a device for recuperation of scale. For Bradley that involves scaling material of immediate presentations under limits. As unrealised commitments of so- called real and ideal are an exclusionary condition of singular comprehension, singularity of judgments is mark of singular reflex with privative force; not some singularity in objects taken in episodic correspondence (...) forming distinctively in singular judgment. The distinguishing input, as it were, to judgment forms is via content in some consequential and fact-like limitive facing of the real. I want to approach Bradley in this slightly negative sense as imposing via inversion some sensible restrictions under some conditions of scaling rather than in direct contact with materials to which one stands in some act of obversion, finally.

I begin this article with an increasingly accepted claim: that emotions lend differential weight to states of affairs, helping us conceptually carve the world and make rational decisions. I then develop a more controversial assertion: that environments have non-subjective emotional qualities, which organize behavior and help us make sense of the world. I defend this from ecological and related embodied standpoints that take properties to be interrelational outcomes. I also build on conceptions of experience as a cultural phenomenon, one that (...) coheres around shared environmental contours and public emotional concerns, introducing normative constraints (or what might be called “world grammars”). Endorsing this outlook suggests an argument for the view that cultural spaces have affectively charged, non-subjective, normative openings and closures. These openings and closures engender selectively permeable barriers which cordon space without physically preventing entry, as seen with decorative half walls and elevation changes. An area with such barriers may look emotionally hostile to, say, the dispirited homeless who are in fact less welcome there. Outcomes like these might be thought of as “political affordances.” These affordances can be regarded as normative openings and closures that implicitly filter, and hence segregate, according to various social divisions. Although registering political affordances requires more than the detection of ambient arrays, the notion retains core Gibsonian ideas: that affordances are values, that these values are linked with how a space can be used, and that the existence and nature of such affordances is not a subjective matter.

We argue that contemporary conceptualizations of “persons” have failed to achieve the moral goals of “person-centred care” (PCC, a model of dementia care developed by Tom Kitwood) and that they are detrimental to those receiving care, their families, and practitioners of care. We draw a distinction between personhood and selfhood, pointing out that continuity or maintenance of the latter is what is really at stake in dementia care. We then demonstrate how our conceptualization, which is one that privileges the lived (...) experiences of people with dementia, and understands selfhood as formed relationally in connection with carers and the care environment, best captures Kitwood’s original idea. This conceptualization is also flexible enough to be applicable to the practice of caring for people at different stages of their dementia. Application of this conceptualization into PCC will best promote the well-being of people with dementia, while also encouraging respect and dignity in the care environment. (shrink)

Epistemologists often claim that in addition to belief and disbelief there is a third, neutral, doxastic attitude. Various terms are used: ‘suspending judgment’, ‘withholding’, ‘agnosticism’. It is also common to claim that the factors relevant to the justification of these attitudes are epistemic in the narrow sense of being factors that bear on the strength or weakness of one’s epistemic position with respect to the target proposition. This paper addresses two challenges to such traditionalism about doxastic attitudes. The first concerns (...) the relevance of non-epistemic factors we might call "future-comparative" – e.g., that you’ll have more decisive evidence on whether p tomorrow – to the justification of suspending judgment. The second, from Jane Friedman, is to explain the point of the neutral attitude without appealing to inquiry and thus taking goal-related factors, which are not epistemic, such as the value of the goal or the prospects for finding means to achieve it, to bear on the justification of the neutral attitude. My defense of traditionalism relies on distinguishing three ways of being neutral on a question: agnosticism, inquiry and suspension of judgment. Traditionalism is saved because, of these, agnosticism alone is a genuine doxastic attitude. (shrink)

Scholars often assert that Plato and Aristotle share the view that discursive thought is internal speech. However, there has been little work to clarify or substantiate this reading. In this paper I show Plato and Aristotle share some core commitments about the relationship of thought and speech, but cash out TIS in different ways. Plato and Aristotle both hold that discursive thinking is a process that moves from a set of doxastic states to a final doxastic state. The resulting judgments (...) can be true or false. Norms govern these final judgments and, in virtue of that, they govern the process that arrives at those judgments. The principal norm is consistency. However, the philosophers differ on the source of this norm. For Plato, persuasiveness and accuracy ground non-contradiction because internal speech is dialogical. For Aristotle, the Principle of Non-Contradiction grounds a Doxastic Thesis that no judgment can contradict itself. For Aristotle, metaphysics grounds non-contradiction because internal speech is monological. (shrink)

This chapter describes the attributionist approach to moral responsibility. Works by Pamela Hieronymi, T.M. Scanlon, Angela Smith, and Matthew Talbert are taken to representative of this approach. On the interpretation given here, attributionism is committed to the following: assessments of moral responsibility are, and ought to be, centrally concerned with the morally significant features of an agent’s orientation toward others that are attributable to her, and an agent is eligible for moral praise or blame solely on the basis of (...) these attributions. Attributionism is presented as rejecting the claim that agents are morally responsible only for what is under their voluntary control, as well as the claim that agents are responsible for wrongdoing only if they could have responded to the moral considerations that spoke against your behavior. These supposed conditions on moral responsibility are rejected for the same reason: agents may reveal features of their selves, in a way that is sufficient for moral responsibility, even in cases in which these conditions are not met.

Pathologies of agency affect both groups and individuals. I present a case study of agential pathology in a group, in which supposedly rogue members of a group act in light of what they take the group’s interests and attitudes to be, but in a way that goes against the group’s explicitly stated agential point of view. I consider several practical concerns brought out by rogue member action in the context of a group agent, focusing in particular on how it undermines (...) the agency of the group and whether or not the group agent itself may be responsible for it.

Different chemical species are often cited as paradigm examples of structurally delimited natural kinds. While classificatory monism may thus seem plausible for simple molecules, it looks less attractive for complex biological macromolecules. I focus on the case of proteins that are most plausibly individuated by their functions. Is there a single, objective count of proteins? I argue that the vagaries of function individuation infect protein classification. We should be pluralists about macromolecular classification.

Soofi1 aims to develop an account of dignity in dementia care based on Nussbaum’s capabilities approach. He does this by drawing on the Kitwood and Bredin2 list of well-being indicators, in order to fill out her account of human flourishing to cover aspects such as practical reasoning that appear beyond the reach of those with relatively severe dementia. As Soofi points out, Nussbaum’s claim that such lost abilities can be compensated through guardianship measures is implausible. He asserts in response that (...) his account of dignity is sufficient to address the desiderata he sets out at the start, including especially the problem of exclusionary implications any putative account should address. So far, so good, but an objection Soofi raises for his own account is that it seems unable to cover cases of severe late-stage dementia. His response is, > …that there is insufficient factual evidence to suggest that people at the very advanced stages of dementia lose all capabilities. But for the sake of argument, let’s suppose that this is true. This, however, still does not undermine the conceptual rigour of the modified version of Nussbaum’s account. This is because the list of the dementia-specific capabilities that I …. (shrink)

Bradley offers a quick and convincing argument that no Boolean semantic theory for conditionals can validate a very natural principle concerning the relationship between credences and conditionals. We argue that Bradley’s principle, Preservation, is, in fact, invalid; its appeal arises from the validity of a nearby, but distinct, principle, which we call Local Preservation, and which Boolean semantic theories can non-trivially validate.

The prevailing view among contemporary analytic philosophers seems to be that, as philosophers, we primarily issue assertions. Following certain suggestions from the work of Rudolf Carnap and Sally Haslanger, I argue that the non-assertoric speech act of stipulation plays a key role in philosophical inquiry. I give a detailed account of the pragmatic structure of stipulations and argue that they are best analyzed as generating a shared inferential entitlement for speaker and audience, a license to censure those who give uptake (...) to the stipulation but do not abide by this entitlement, and as justified on the basis of the speaker and audience's shared ends. In presenting this account, I develop a novel taxonomy for making sense of criticisms of speech act performances generally and clarify the notions of successful speech act performance and uptake. To demonstrate the fruitfulness of this view of stipulation for recasting and advancing philosophical disputes, I apply my account to two case studies – the first concerns Iris Marion Young's analysis of the concept of oppression and the second involves Saul Kripke's and Hilary Putnam's accounts of the concept of reference.

Anti-exceptionalism about logic is the thesis that logic is not special. In this paper, I consider, and reject, a challenge to this thesis. According to this challenge, there are basic logical principles, and part of what makes such principles basic is that they are epistemically exceptional. Thus, according to this challenge, the existence of basic logical principles provides reason to reject anti-exceptionalism about logic. I argue that this challenge fails, and that the exceptionalist positions motivated by it are thus unfounded. (...) I make this case by disambiguating two senses of ‘basic’ and showing that, once this disambiguation is taken into account, the best reason we have for thinking that there are basic principles actually implies that those principles do not require a special epistemology. Consequently, the existence of basic logical principles provides reason to accept, rather than reject, anti-exceptionalism concerning the epistemology of logic. I conclude by explaining how an abductivist, anti-exceptionalist approach to the epistemology of logic can accommodate the notion of basic logical principles. (shrink)

In this paper I argue that presentism has a problem accounting forthe truth of statements whose truth conditions seem to require therebe relations that hold between present and non-present objects. Imotivate the problem and then examine several strategies for dealingwith the problem. I argue that no solution is forthcoming, and thispresents a prima facie problem for presentism.

In this paper, we use antecedent-final conditionals to formulate two problems for parsing-based theories of presupposition projection and triviality of the kind given in Schlenker 2009. We show that, when it comes to antecedent-final conditionals, parsing-based theories predict filtering of presuppositions where there is in fact projection, and triviality judgments for sentences which are in fact felicitous. More concretely, these theories predict that presuppositions triggered in the antecedent of antecedent-final conditionals will be filtered (i.e. will not project) if the negation (...) of the consequent entails the presupposition. But this is wrong: John isn’t in Paris, if he regrets being in France intuitively presupposes that John is in France, contrary to this prediction. Likewise, parsing-based approaches to triviality predict that material entailed by the negation of the consequent will be redundant in the antecedent of the conditional; but John isn’t in Paris, if he’s in France and Mary is with him is intuitively felicitous, contrary to these predictions. Importantly, given that the trigger appears in sentence-final position, both incremental (left-to-right) and symmetric versions of such theories make the same predictions. These data constitute a challenge to the idea that presupposition projection and triviality should be computed on the basis of parsing. This issue is important because it relates to the more general question as to whether presupposition and triviality calculation should be thought of as a pragmatic post-compositional phenomenon or as part of compositional semantics (as in the more traditional dynamic approaches). We discuss a solution which allows us to maintain the parsing-based pragmatic approach; it is based on an analysis of conditionals which incorporates a presupposition that their antecedent is compatible with the context, together with a modification to Schlenker’s (2009) algorithm for calculating local contexts so that it takes into account presupposed material. As we will discuss, this solution works within a framework broadly similar to that of Schlenker’s (2009), but it doesn’t extend in an obvious way to other parsing-based accounts (e.g. parsing-based trivalent approaches). We conclude that a parsing-based theory can be maintained, but only if we adopt a substantial change of perspective on the framework. (shrink)

Using the example of recent attempts to engineer the concept of conspiracy theory, I argue that philosophers should be far more circumspect in their approach to conceptual engineering than we have been – in particular, that we should pay much closer attention to the history behind and context that surrounds our target concept in order to determine whether it is a site of what I have elsewhere called ‘conceptual domination’. If it is, we may well have good reason to avoid (...) engineering. In their recent ‘What is a Conspiracy Theory?’, M. Giulia Napolitano and Kevin Reuter argue that the disagreement between generalists and particularists in the literature on conspiracy theories is best characterized as a set of dueling conceptual engineering projects. While I agree with their turn to this metaphilosophical literature, I give a very different account of its applicability. Particularists, on my account, are better read as aiming to diagnose the ways in which many discussions of the concept of conspiracy theories are a form of conceptual domination, where this broader context should then prompt us to abandon or block any concept of conspiracy theory that treats its referents as inherently defective. Broader metaphilosophical lessons are drawn. (shrink)

Predictive processing theorists have claimed PTSD and depression are maladaptive and epistemically distorting because they entail undesirably wide gaps between top-down models and bottom-up information inflows. Without denying this is sometimes so, the “maladaptive” label carries questionable normative assumptions. For instance, trauma survivors facing significant risk of subsequent attacks may overestimate threats to circumvent further trauma, “bringing forth” concretely safer personal spaces, to use enactive terminology, ensuring the desired gap between predicted worries and outcomes. The violation of predictive processing can (...) go in the opposite direction too, as when depression coincides with energy-depletion, and hence objectively strenuous situations in which things look farther away because they are (accurately anticipated to be) harder to reach. These examples partly encapsulate what predictive processing theorists call “active inference,” yet with differences. In the first case, actions fruitfully obviate predictions rather than fulfilling them. In the second, mental models do not dysregulate bodily processes, making coping harder. Instead, problems (e.g., personal obstacles, gastric illness) deplete energy, eliciting a depressive and adaptive slow-down. Some predictive proponents apply correspondence criteria when alleging mismatches between internal models and the world, while incongruously asserting that the brain did not evolve to see things veridically, but to execute actions. An alternative is to adopt pluralistic, pragmatic epistemologies suited to the complexity of mind. The upshot is that mental outlooks can depart from the norm without epistemically being distorted and that mismatches between anticipatory worries and outcomes, when they actually exist, can be a measure of adaptive and epistemic success.

What is the relationship between lying, belief, and knowledge? Prominent accounts of lying define it in terms of belief, namely telling someone something one believes to be false, often with the intent to deceive. This paper develops a novel account of lying by deriving evaluative dimensions of responsibility from the knowledge norm of assertion. Lies are best understood as special cases of vicious assertion; lying is the anti-paradigm of proper assertion. This enables an account of lying in terms of knowledge: (...) roughly, lying is telling someone something you know ain't so. (shrink)

Much of the discussion of the role of emerging technologies associated with AI, machine learning, digital simulacra, and relevant ethical considerations such as those discussed in the target article, take a relatively narrow and episodic view of a person’s healthcare needs. There is much speculation about diagnostic, treatment, and predictive applications but relatively little consideration of how such technologies might be used to address a person’s lived experience of illness and ongoing care needs. This is likely due to the greater (...) weight or priority given to acute care needs and the role of medical treatment in care provision, but it may also reflect the limitations of current technologies and our limited vision of their potential application. Such limitations are not surprising given that we are still grappling with the complexities and nuances of achieving the ethical and humanistic ideals of care, namely, care that addresses the hermeneutical, relational, contextual, temporal, and agential dimensions of a person’s health and wellbeing.

The problem of creeping minimalism concerns how to tell the difference between metaethical expressivism and its rivals given contemporary expressivists’ acceptance of minimalism about truth and related concepts. Explanationism finds the difference in what expressivists use to explain why ethical language and thought has the content it does. I argue that two recent versions of explanationism are unsatisfactory and offer a third version, subject matter explanationism. This view, I argue, captures the advantages of previous views without their disadvantages and gives (...) us a principled and general characterisation of non-representational views about all kinds of language and thought.

Fifty years have passed since Norwood Russell Hanson's unexpected death, yet he remains an important voice in philosophy of science. This book is a revised and expanded edition of a collection of Hanson's essays originally published in 1971, edited by Stephen Toulmin and Harry Woolf. The new volume features a comprehensive introduction by Matthew Lund (Rowan University) and two new essays. The first is "Observation and Explanation: A Guide to Philosophy of Science", originally published as a posthumous book by (...) Harper and Row. This essay, written near the end of Hanson’s life, represents his mature philosophy of science. The second new addition, Hanson's essay "The Trial of Galileo", is something of a "lost" work – it was only published in a small run collection on famous trials and was left out of the published lists of Hanson’s works. Ever the outspoken firebrand, Hanson found many lessons and warnings from Galileo's trial that were relevant to Cold War America. -/- This volume not only contains Hanson's best-known work in history and philosophy of science, but also highlights the breadth of his philosophical thought. Hanson balanced extreme versatility with a unified approach to conceptual and philosophical problems. Hanson's central insight is that philosophy and science both strive to render the world intelligible -- the various concepts central to our attempts to make sense of the world are interdependent, and cannot operate, or even be fully understood, independently. The essays included in this collection present Hanson's thinking on religious belief, theory, observation, meaning, cosmology, modality, logic, and philosophy of mind. This collection also includes Hanson's lectures on the theory of flight, Hanson's greatest passion. (shrink)

Conspiracy theories are typically thought to be examples of irrational beliefs, and thus unlikely to be warranted. However, recent work in Philosophy has challenged the claim that belief in conspiracy theories is irrational, showing that in a range of cases, belief in conspiracy theories is warranted. However, it is still often said that conspiracy theories are unlikely relative to non-conspiratorial explanations which account for the same phenomena. However, such arguments turn out to rest upon how we define what gets counted (...) both as a ‘conspiracy’ and a ‘conspiracy theory’, and such arguments rest upon shaky assumptions. It turns out that it is not clear that conspiracy theories are prima facie unlikely, and so the claim that such theories do not typically appear in our accounts of the best explanations for particular kinds of events needs to be reevaluated.

In this chapter, I examine how Dewey circumnavigated debates between empiricists and a priorists by showing that active bodies can perform integrative operations traditionally attributed to “inner” mechanisms, and how he thereby realized developments at which the artificial intelligence, robotics and cognitive science communities only later arrived. Some of his ideas about experience being constituted through skills actively deployed in cultural settings were inspired by ancient Greek sources. Thus in some of his more radical moments, Dewey refined rather than invented (...) the wheel, and I suggest that prominent embodiment figures have done the same, Dewey having anticipated them, particularly Noë and his version of enactivism. I urge that cognitive science may progress into relatively unexplored territory by traveling Dewey’s historically sensitive path. (shrink)

The Knowledge Norm or Knowledge Account of Assertion (KAA) has received added support recently from data on prompting assertion (Turri 2010) and from a refinement suggesting that assertions ought to express knowledge (Turri 2011). This paper adds another argument from parenthetical positioning, and then argues that KAA’s unified explanation of some of the earliest data (from Moorean conjunctions) adduced in its favor recommends KAA over its rivals.

What do we owe each other when we act together? According to normativists about collective action, necessarily something and potentially quite a bit. They contend that collective action inherently involves a special normative status amongst participants, which may, for example, involve mutual obligations to receive the concurrence of the others before leaving. We build on recent empirical work whose results lend plausibility to a normativist account by further investigating the specific package of mutual obligations associated with collective action according to (...) our everyday understanding. However, our results cast doubt on a proposed obligation to seek the permission of co-actors before exiting a collective action, and suggest instead that this obligation is a function of explicit promising. We then discuss how our results pave the path for a new normativism, a theory that neither under- nor overshoots the target given by our common conception of the interpersonal obligations present in collective action.*.

I argue that that an influential strategy for understanding conspiracy theories stands in need of radical revision. According to this approach, called ‘generalism’, conspiracy theories are epistemically defective by their very nature. Generalists are typically opposed by particularists, who argue that conspiracy theories should be judged case-by-case, rather than definitionally indicted. Here I take a novel approach to criticizing generalism. I introduce a distinction between ‘Dominant Institution Conspiracy Theories and Theorists’ and ‘Non-Dominant Institution Conspiracy Theories and Theorists’. Generalists uncritically center (...) the latter in their analysis, but I show why the former must be centered by generalists’ own lights: they are the clearest representatives of their views, and they are by far the most harmful. Once we make this change in paradigm cases, however, various typical generalist theses turn out to be false or in need of radical revision. Conspiracy theories are not primarily produced by extremist ideologies, as generalists typically claim, since mainstream, purportedly non-extremist political ideologies turn out to be just as, if not more responsible for such theories. Conspiracy theories are also, we find, not the province of amateurs: they are often created and pushed by individuals widely viewed as experts, who have the backing of our most prestigious intellectual institutions. While generalists may be able to take this novel distinction and shift in paradigm cases on board, this remains to be seen. Subsequent generalist accounts that do absorb this distinction and shift will look radically different from previous incarnations of the view. (shrink)

Matti Eklund has argued that a new problem in metanormative theory arises when we consider the possibility of "normative counterparts"—normative concepts with the same normative roles as OUGHT and RIGHT, but with different extensions. I distinguish two versions of the problem, and propose a solution: when we attend to the attitudinal commitments involved in the possession and application of some normative concepts, we find that tolerance for the possibility of normative counterparts is rationally ruled out.

What is it to know someone? Epistemologists rarely take up this question, though recent developments make such inquiry possible and desirable. This paper advances an account of how such interpersonal knowledge goes beyond mere propositional and qualitative knowledge about someone, giving a central place to second-personal treatment. It examines what such knowledge requires, and what makes it distinctive within epistemology as well as socially. It assesses its theoretic value for several issues in moral psychology, epistemic injustice, and philosophy of mind. (...) And it offers an account of the complex content in play if interpersonal knowledge is to be understood in terms of its mental states and their functions. (shrink)

This article contemplates symbols and values inscribed on Cairo’s landscape during the 2011 revolution and the period since, focusing on Tahrir Square and the role of the Egyptian flag in street discourses there. I start by briefly pondering how intertwined popular narratives readied the square and flag as emblems of dissent. Next I examine how these appropriations shaped protests in the square, and how military authorities who retook control in 2013 re-coopted the square and flag, with the reabsorption of each (...) critical to that of the other and executed in the same place: Tahrir. Pro-military factions have created the pretense that they were for the revolution by altering the square and structures around it. Furthermore, the square has remained open to the public, but ceased to be inviting. This relates to post-revolutionary alterations that psychologically repel entry. I consider these changes in light of affordance theory, value sensitive design research and especially the defensible space model, arguing that Tahrir Square has been symbolically cordoned and closed.
