Many philosophers have thought that our folk, or pre-reflective, view of persistence is one on which objects endure. This assumption not only plays a role in disputes about the nature of persistence itself, but is also put to use in several other areas of metaphysics, including debates about the nature of change and temporal passage. In this paper, we empirically test three broad claims. First, that most people (i.e. most non-philosophers) believe that, and it seems to them as though, objects (...) persist by enduring rather than perduring. Second, that most people have a view of change on which enduring but not perduring objects count as changing. Third, that one reason why the folk represent time as dynamical is because it seems to them, and they believe that, they endure through time. We found no evidence to support these claims. While there are certainly plenty of ‘folk’ endurantists in the population we tested, there are also plenty of ‘folk’ perdurantists. We did not find robust evidence that a majority of people believed that, or it seemed to them as though, objects endure rather than perdure. We conclude that many arguments in favour of endurantism that appeal to folk beliefs about, or experiences of, persisting objects and change rest on views about those beliefs and experiences that are empirically unsupported. There is no evidence to suggest that endurantism is the folk friendly view of persistence, and so we should stop treating it as such without argument. (shrink)

In this paper, I argue that Kant has a far more communitarian theory of aesthetic life than is usually acknowledged. I focus on two aspects of Kant’s theory that might otherwise be taken to support an individualist reading, namely, Kant’s emphasis on aesthetic autonomy and his characterization of judgments of taste as involving demands for agreement. I argue that the full expression of autonomy in fact requires being a member of an aesthetic community and that within such a community, judgments (...) of taste are issued as invitations to others to engage their faculties towards the goal of shared aesthetic appreciation.

While philosophical questions about health and disease have attracted much attention in recent decades, and while opinions are divided on most issues, influential accounts seem to embrace negativism about health, according to which health is the absence of disease. Some subscribe to unrestricted negativism, which claims that negativism applies not only to the concepts of health and disease as used by healthcare professionals but also to the lay concept that underpins everyday thinking. Whether people conceptualize health in this manner has (...) implications for medical care and public health, and so we set out to examine this claim in two studies. Participants were asked to assess and compare the health states of two people presented in two vignettes. We found that both lay people and medical students conceptualize health as something more than the absence of disease. We argue that our findings highlight a need to rethink unrestricted negativism and indicate a need to rethink the way the debate has traditionally focused on disease. (shrink)

In recent years, philosophers have identified a number of moral and psychological harms associated with the attention economy (Alysworth & Castro, 2021; Castro & Pham, 2020; Williams, 2018). Missing from many of these accounts of the attention economy, however, is what exactly attention is. As a result of this neglect of the cognitive science of attention, many of these accounts are not empirically credible. They rely on oversimplified and unsophisticated accounts of not only attention, but self- control, and addiction as (...) well. Of note are accounts of the attention economy that rely on the ‘brain disease’ rhetoric of addiction and subsequent control failures (Aylsworth & Castro, 2021; Bhargava & Velasquez, 2021), accounts that rely on a strict dichotomy of top-down vs. bottom-up attention (Williams, 2018; Aylsworth & Castro, 2021), and accounts that construe attention as a limited resource (Williams, 2018). -/- Drawing on recent work from the neuroscience and psychology of attention, I demonstrate the shortcomings of these accounts and sketch a way forward for an empirically grounded account of the attention economy. These accounts tend to uphold strict dichotomies of voluntary control (e.g., compulsion versus choice, dual-process models of self-control, and top-down versus bottom-up) that cannot account for the complexities of attentional control, mental agency, and decision-making. As such, these empirically and conceptually impoverished accounts cannot adequately address the current so-called crisis of attention. To better understand the harms associated with the attention economy, we need an empirically responsible account of the nature and function of attention and mental agency. (shrink)

In the topic-sensitive theory of the logic of imagination due to Berto (2018a), the topic of the imaginative output must be contained within the imaginative input. That is, imaginative episodes can never expand what they are about. We argue, with Badura (2021), that this constraint is implausible from a psychological point of view, and it wrongly predicts the falsehood of true reports of imagination. Thus the constraint should be relaxed; but how? A number of direct approaches to relaxing the controversial (...) content-inclusion constraint are explored in this paper. The core idea is to consider adding an expansion operator to the mereology of topics. The logic that results depends on the formal constraints placed on topic expansion, the choice of which are subject to philosophical dispute. The rst semantics we explore is a topological approach using a closure operator, and we show that the resulting logic is the same as Berto's own system. The second approach uses an inclusive and monotone increasing operator, and we give a sound and complete axiomatisation for its logic. The third approach uses an inclusive and additive operator, and we show that the associated logic is strictly weaker than the previous two systems, and additivity is not de nable in the language. The latter result suggests that involved techniques or a more expressive language is required for a complete axiomatization of the system, which is left as an open question. All three systems are simple tweaks on Berto's system in that the language remains propositional, and the underlying theory of topics is unchanged. (shrink)

Recently, a version of realism has been offered to address the simplification strategies used in computational neuroscience. According to this view, computational models provide us with knowledge about the brain, but they should not be taken literally in _any_ sense, even rejecting the idea that the brain performs computations (computationalism). I acknowledge the need for considerations regarding simplification strategies in neuroscience and how they contribute to our interpretations of computational models; however, I argue that whether we should accept or reject (...) computationalism about the brain is a separate issue that can be addressed independently by a philosophical theory of physical computation. This takes seriously the idea that the brain performs computations while also taking an analogical stance toward computational models in neuroscience. I call this version of realism “Analogical Computational Realism.” Analogical Computational Realism is a realist view in virtue of being committed to computationalism while taking certain computational models to pick out real patterns that provide a how-possibly explanation without also thinking that the model is literally implemented in the brain.

It is commonly assumed that images, whether in the world or in the head, do not have a privileged analysis into constituent parts. They are thought to lack the sort of syntactic structure necessary for representing complex contents and entering into sophisticated patterns of inference. I reject this assumption. “Image grammars” are models in computer vision that articulate systematic principles governing the form and content of images. These models are empirically credible and can be construed as literal grammars for images. (...) Images can have rich syntactic structure, though of a markedly different form than sentences in language. (shrink)

In his Encomium of Helen and On Not Being, Gorgias of Leontinoi discusses the nature and function of speech more extensively than any other surviving author before Plato. His discussions are not only surprising in the way they characterize the power of logos and its effects on a listener but also in how the two descriptions of speech seem to contradict one another. In the Helen, Gorgias claims that logos is a very powerful entity, capable of affecting a listener in (...) whatever way it wants. In On Not-Being, he makes the very different (but no less exaggerated) claim that logos is a non-entity, incapable of referring to anything other than itself. In this essay I show how these apparently contradictory accounts might be brought into harmony with one another.2 In the first part I address some of the interpretive difficulties with the text of Gorgias’s On Not Being (henceforth ONB) and the role that irony plays in the work. In particular I argue (as others have before) that Gorgias’s remarks about the impotency of speech are not meant to be taken seriously. Instead, they are aimed more squarely at raising questions about how exactly speech is thought to function and, more specifically, how linguistic reference works—i.e., how words somehow correspond to things, on one level, and to our ideas about things, on another. In the second and third parts of this paper, I illustrate how Gorgias’s concern with linguistic reference in ONB goes on to inform his notion of logos in the Encomium of Helen. I point specifically to evidence found in an important and often overlooked exit clause at the close of ONB regarding the difference between words and things. There, Gorgias insists that if words manifest meaning at all, they must appeal to their own sort of sense organ. In the Helen, he draws on the concepts of soul (psychē) and opinion (doxa) in order to construct this alternative, psychagogic account in which utterances are actually apprehended in ways akin to sense perception. Whether or not one is convinced by Gorgias’s alternative account of how speech works, the description he gives of logos does notionally circumvent the problem of linguistic reference and, in doing so, pushes one to think beyond the potentially constrictive framework of nomen et nominatum. I argue that, when read in this way, these two early discussions of logos represent a unified progression of serious thought about how speech works. (shrink)

Prior research has unveiled a pathologization effect where individuals perceived as having bad moral character are more likely to have their conditions labeled as diseases and are less often considered healthy compared to those viewed as having a good moral character. Moreover, these individuals are perceived as less unlucky in their affliction and more deserving of it. This study explores the broader impacts of moral character on such judgments, hypothesizing that these effects reach deeper and extend to both negative and (...) positive moral evaluations. The pathologization effect also raises concerns about potential discrimination and the overmedicalization of normal health variations, so we also examine whether providing more detailed descriptions of conditions mitigates the influence of judgments of moral character. The methodology and broader implications of our findings are discussed, emphasizing the need for a deeper understanding of how moral judgments might influence patient care. (shrink)

In the Critique of Judgment, Kant claims that genius is a talent for art, but not for science. Despite his restriction of genius to the domain of fine art, several recent interpreters have suggested that genius has a role to play in Kant’s account of cognition in general and scientific practice in particular. In this paper, I explore Kant’s reasons for excluding genius from science as well as the reasons that one might nevertheless be tempted to think that his account (...) allows room for the scientific genius. I then argue that Kant’s concerns are not only epistemic, but also moral, and together, they give us good reason for resisting the veneration of genius. (shrink)

Christopher Hill's Perceptual experience is a must‐read for philosophers of mind and cognitive science. Here I consider Hill's representationalist account of spatial perception. I distinguish two theses defended in the book. The first is that perceptual experience does not represent the enduring, intrinsic properties of objects, such as intrinsic shape or size. The second is that perceptual experience does represent certain viewpoint‐dependent properties of objects—namely, Thouless properties. I argue that Hill's arguments do not establish the first thesis, and then I (...) raise questions about the Thouless‐property view and its role in Hill's defense of representationalism. (shrink)

Under what conditions are material objects, such as particles, parts of a whole object? This is the composition question and is a longstanding open question in philosophy. Existing attempts to specify a non-trivial restriction on composition tend to be vague and face serious counterexamples. Consequently, two extreme answers have become mainstream: composition (the forming of a whole by its parts) happens under no or all conditions. In this paper, we provide a self-contained introduction to the integrated information theory of consciousness (...) (IIT). We show that IIT specifies a non-trivial restriction on composition: composition happens when integrated information is maximized. We compare the IIT-restriction to existing proposals and argue that the IIT-restriction has significant advantages, especially in response to the problems of vagueness and counterexamples. An appendix provides an introduction to calculating parts and wholes with a simple system. (shrink)

This paper proposes to reorient the philosophical debate about peer disagreement. The problem of peer disagreement is normally seen as a problem about the extent to which disagreement provides one with evidence against one's own conclusions. It is thus regarded as a problem for individual inquiry. But things look different in more collaborative contexts. Ethical norms relevant to those contexts make a difference to the epistemology. In particular, we argue that a norm of mutual answerability applies to us when we (...) engage in shared inquiry with others, and precludes us from treating one another's conflicting judgments as evidence relevant to the dispute. From this it follows that standard philosophical accounts of peer disagreement—e.g., the Equal Weight View and the Total Evidence View—presuppose that the disagreeing parties are in a sense alienated from one another. It's doubtful that such forms of alienated disagreement should be treated as the central case. (shrink)

Automated influence is one of the most pervasive applications of artificial intelligence in our day-to-day lives, yet a thoroughgoing account of its associated individual and societal harms is lacking. By far the most widespread, compelling, and intuitive account of the harms associated with automated influence follows what I call the control argument. This argument suggests that users are persuaded, manipulated, and influenced by automated influence in a way that they have little or no control over. Based on evidence about the (...) effectiveness of targeted advertising as well as empirical results about the nature of attentional control, I provide reasons to reject this argument. In turn, I use C. Thi Nguyen’s theory of value collapse to develop a new account of the harmfulness of automated influence. (shrink)

Does the evidence that our universe contains fine-tuned life confirm the multiverse hypothesis? The answer depends on our approach to self-locating beliefs. In a recent paper, Isaacs, Hawthorne, and Russell (2022) offer two arguments for thinking that such evidence does confirm the multiverse hypothesis. First, they argue that the three leading approaches to self-locating beliefs all entail that such evidence confirms the multiverse hypothesis. Second, they present a pair of theorems showing that any approach to self-locating beliefs that satisfies certain (...) “reasonable” constraints will entail that such evidence confirms the multiverse hypothesis. I argue that Isaacs, Hawthorne, and Russell’s two arguments are not compelling, the first because they fail to consider some natural approaches to self-locating beliefs, the second because their theorems rely on a suspect premise that we should reject. Contra Issacs, Hawthorne, and Russell, I argue that on a natural approach to self-locating beliefs the evidence that our universe contains fine-tuned life needn’t confirm the multiverse hypothesis.

A prominent view holds that perception and memory are distinguished at least partly by their temporal orientation: Perception functions to represent the present, while memory functions to represent the past. Call this view perceptual presentism. This chapter critically examines perceptual presentism in light of contemporary perception science. I adduce evidence for three forms of perceptual sensitivity to the past: (i) shaping perception by past stimulus exposure, (ii) recruitment of mnemonic representations in perceptual processing, and (iii) perceptual representation of present objects (...) as possessing past properties. I argue that forms (i) and (ii) are consistent with perceptual presentism, while form (iii) poses a genuine threat to the view. While the empirical case for form (iii) remains inconclusive, I suggest that the most serious challenges to perceptual presentism derive from representations that integrate mnemonic and present-tensed elements in the performance of canonical perceptual functions, such as perceiving object continuity over time.

How do people understand the concepts of mental health and disorder? The objective of this paper is to examine the impact of several factors on people’s judgments about whether a condition constitutes a mental disorder or a healthy state. Specifically, this study examines the impact of the source of the condition, its outcome, individual valuation (i.e., the value the individual attaches to the condition), and group valuation (i.e., the value the relevant group attaches to the condition). While we find that (...) people’s health and disorder judgments are driven by perceived dysfunction, we also find that health and disorder judgments are impacted differently by these factors. Health judgements are impacted by outcome and individual valuation, and disorder judgments are impacted by condition source. These results suggest that the folk concept of mental health is positive (i.e., mental health is more than the absence of mental disorder) and normativist (i.e., value judgments play a significant role in determining whether a condition counts as healthy), while the concept of mental disorder aligns with a naturalist perspective, at least to the extent that dysfunction plays an important role in categorizing a condition as a disorder. However, our finding that people’s dysfunction judgments are influenced by individual valuation and outcomes poses a strong challenge to naturalist accounts. To provide access to our supplementary data, an appendix has been included. (shrink)

Debates about the genuine disease status of controversial diseases rely on intuitions about a range of factors. Adopting tools from experimental philosophy, this paper explores some of the factors that influence judgments about whether low sexual desire should be considered a disease and whether it should be medically treated. Drawing in part on some assumptions underpinning a divide in the literature between viewing low sexual desire as a genuine disease and seeing it as improperly medicalized, we investigate whether health and (...) disease judgments are affected by factors such as an individual’s gender, the cause of the low desire, whether the desire is high or low, and both personal and societal valuations of the condition. Our main findings indicate that (a) the cause of a condition influences whether it is judged a disorder, (b) how the individual values the condition influences whether the condition is seen as a proper target of medical intervention, and (c) perceived dysfunction influences judgments regarding health, disorder classification, medicalization, and medical intervention. Our findings help further illuminate the intricate interplay of factors that influence judgments about health and disease in controversial conditions. (shrink)

Disagreement is one of the deepest and most pervasive topics in philosophy, arguably its very bedrock, and is an ever-increasing feature of politics, ethics, public policy, science and many other areas. Despite the omnipresence of disagreement, the topic itself has received relatively little sustained examination. In this outstanding handbook a team of international contributors examines the philosophy of disagreement and how it extends to debates in public policy and science. Comprising forty-one chapters by an international team of contributors, the Handbook (...) is divided into six clear parts: Philosophy of Disagreement Epistemology of Disagreement Disagreement about Science Moral Disagreement Disagreement in Politics Disagreement in Public Policy Within these sections key topics are examined, including: skepticism, truth, pluralism, feminist philosophy, experimental philosophy, epistemology of peer disagreement, rationality, intellectual virtue, relativism, realism, instrumentalism, scientific method and perspectivism. Ideal for those studying and researching philosophy, especially epistemology, ethics and philosophy of science, this handbook will also be of interest to those in related disciplines such as politics, social policy, and law.

In this paper, I argue for a fundamentally different kind of moral luck, Patient Moral Luck (PML). Unlike traditional moral luck, PML concerns the amount of moral consideration that different moral patients — that is, creatures (including human beings) with moral status — will be owed, independent of factors in their control. PML, I argue, entails that morality itself appears to sanction and even obligate actions which, along predictable patterns, involve repeatedly failing to equally consider certain moral patients - and (...) repeatedly the same people - over sustained periods of time, through no fault of their own. And often these people will be members of groups who are already worse off through no fault of their own, thus exacerbating unjust inequalities. I defend the existence and normative puzzle of PML by introducing the notion of “moral force” - roughly, the amount of considerative weight a given moral patient is owed by some deliberating agent or group of agents. I then argue that this will vary widely between different moral patients through no fault or credit of their own. This, I claim, is inconsistent with the intuition that supports Equal Consideration principles in moral theory. I conclude by considering how we can minimize or mitigate PML without a radically revisionary normative theory. (shrink)

One proposed explanation for a particular kind of temporal preference lies in a disparity between the emotional intensity of memory compared to anticipation. According to the memory/anticipation disparity explanation, the utility of anticipation of a particular event if that event is future, whether positive or negative, is greater than the utility of retrospection of that same event if it is past, whether positive or negative, and consequently, overall utility is maximised when we prefer negative events to be located in the (...) past rather than the future, and positive ones in the future rather than the past. To have this preference is to be (at least apparently) future biased. If this explanation is correct, it would tend to confer rational justification upon these preferences. This paper empirically investigates this explanation. Our results suggest that, at most, this explanation might be a partial one of some people’s preferences some of the time, rather than a general explanation of future bias. In turn, this lends some indirect support to a competing explanation that appeals to temporal asymmetries in emotion and attention. Since that explanation would arguably tend not to confer rational justification upon (apparently) future-biased preferences, we argue that our findings provide some reason to be sceptical that these preferences are, in general, rationally justified.

A naturalistic theory of intentionality is proposed that differs from previous evolutionary and tracking theories. Full-blown intentionality is constructed through a series of evolvable refinements. A first, minimal version of intentionality originates from a conjectured internal process that estimates an organism’s own fitness and that continually modifies the organism. This process produces the directedness of intentionality. The internal estimator can be parsed into intentional components that point to components of the process that produces fitness. It is argued that such intentional (...) components can point to mistaken or non-existing entities. Different Fregian senses of the same reference correspond to different components that have different roles in the estimator. Intentional components that point to intentional components in other organisms produce directedness towards semi-abstract entities. Finally, adding a general, population-wide means of communication enables intentional components that point to fully abstract entities. Intentionality thus naturalized has all of its expected properties: being directed; potentially making errors; possibly pointing to non-existent, abstract, or rigid entities; capable of pointing many-to-one and one-to-many; distinguishing sense and reference; having perspective and grain; and having determinate content. Several examples, such as ‘swampman’ and ‘brain-in-a-vat’, illustrate how the theory can be applied. (shrink)

In the present study, we tested whether civic identity consisting of moral and political identity via the bifactor model of civic identity with the Stanford Civic Purpose dataset. Previous research in youth development proposed that civic identity consists of two closely related identity constructs, i.e., moral and political identity. Given the bifactor model in factor analysis assumes the presence of both the general and specific factors, we hypothesized that the bifactor model would better fit the data than conventional alternative models. (...) Thus, we compared the candidate models, including the bifactor model, with confirmatory factor analysis. To address the concern about the potential overfitting of the bifactor model, we additionally conducted cross-validation and measurement invariance tests across different gender groups and time points. The analysis results supported our hypothesis that the bifactor model better fitted the data. Both the cross-validation and measurement invariance test results suggested that the overfitting issue was not a significant concern. In the present study, we empirically demonstrated that the bifactor model of civic identity consisting of moral and political identity, which was supposed to be more consistent with the theoretical and conceptual framework of civic identity, better fitted the data than conventional alternative models.

While many aspects of cognition have been shown to be shared between humans and non-human animals, there remains controversy regarding whether the capacity to mentally time travel is a uniquely human one. In this paper, we argue that there are four ways of representing when some event happened: four kinds of temporal representation. Distinguishing these four kinds of temporal representation has five benefits. First, it puts us in a position to determine the particular benefits these distinct temporal representations afford an (...) organism. Second, it provides the conceptual resources to foster a discussion about which of these representations is necessary for an organism to count as having the capacity to mentally time travel. Third, it enables us to distinguish stricter from more liberal views of mental time travel that differ regarding which kind(s) of temporal representation is taken to be necessary for mental time travel. Fourth, it allows us to determine the benefits of taking a stricter or more liberal view of mental time travel. Finally, it ensures that disagreement about whether some species can mentally time travel is not merely the product of unrecognised disagreement about which temporal representation is necessary for mental time travel. We argue for a more liberal view, on the grounds that it allows us to view mental time travel as an evolutionarily continuous phenomenon, and to recognise that differences in the ways that organisms mentally time travel might reflect different temporal representations, or combinations thereof, that they employ. Our ultimate aim, however, is to create the conceptual framework for further discussion regarding what sorts of temporal representations are required for mental time travel. (shrink)

Empirical evidence suggests that a majority of people believe that time robustly passes, and that many also report that it seems to them, in experience, as though time robustly passes. Non-dynamists deny that time robustly passes, and many contemporary non-dynamists—deflationists—even deny that it seems to us as though time robustly passes. Non-dynamists, then, face the dual challenge of explaining why people have such beliefs and make such reports about their experiences. Several philosophers have suggested the stable-self explanation, according to which (...) what partly explains one or both of the explananda is that people believe themselves to have a stable persisting self which is imagined either as moving through time, or as being stationary, with time moving around it. This paper empirically investigates this explanation. We found, however, no evidential support for the stable-self explanation, leaving the non-dynamist but also, we will argue, the dynamist, with an extant explanatory challenge. (shrink)

Biodiversity loss is an immense ecological crisis of our time. But while “biodiversity” has become a buzzword in media and policy, conservationists have found it difficult to build a common understanding on the nature and severity of biodiversity loss and the means to tackle it. Perhaps surprisingly, many biologists and philosophers have proposed that biodiversity might be best defended with reference to its aesthetic value. This article explores whether aesthetic values could provide strong support for biodiversity conservation. By exploring the (...) question from the viewpoints of species diversity, ecosystem diversity, and genetic diversity, we argue that there is a mismatch between apparent and real biodiversity and that aesthetics can, at best, give only limited support for biodiversity conservation.

This paper explores two related questions in late Athenian and Alexandrian Neoplatonism. First, how can a philosopher contemplate the eternal Forms while engaging in practical agency in the world? Second, do Neoplatonists provide a consistent account of the philosopher’s progress through the ‘stages of virtue’ (βαθμοί τῶν ἀρετῶν), the conceptual structure that underpins late antique philosophical curricula and hagiography? These questions interact, I suggest, because later Platonists appeal to the stages of virtue and divine maniai (βαθμοί τῶν μανίων) to explain (...) the philosopher’s ability to alternate gracefully between contemplation and embodied agency, and even to engage in both activities at the same moment. I argue that apparently contradictory evidence for the highest stages of virtue can be reconciled satisfactorily, shedding light on two models of ethical and perceptual transformation that are consistent throughout later Neoplatonism. In the first, 'painterly' model, we alternate between a vision of the paradigmatic model and its expression in the media of place and time; in the second, 'dancerly' model, we contemplate in action all at once, like a dancer moving to the music.

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.

We investigate the causal manipulability hypothesis, according to which what partly explains (a) why people tend to prefer negative events to be in their further future rather than their nearer future and positive events to be in their nearer future rather than their further future and (b) why people tend to prefer that negative events be located in their past not their future and that positive events be located in their future not their past, is that people tend to discount (...) the value of events they are less able causally to manipulate. If people discount the value of events they are less able to causally manipulate, then since often temporally nearer future events are more causally manipulable than further ones, and since future events are manipulable whereas past ones aren’t, this could explain both (a) and (b). In turn, if the causal manipulability hypothesis is correct, this might suggest that insofar as people’s preferences are explained in this manner, those preferences are rationally permissible, since relative causal manipulability is normatively relevant. Thus, ascertaining whether the causal manipulability hypothesis is true may shed light on the normative status of such preferences. We investigate the cognitively mediated version of the causal manipulability hypothesis, according to which people’s consciously held beliefs about the relative causal manipulability of events explains (a) and (b). Contrary to expectations, we found no evidence in favour of this view. We suggest that either relative causal manipulability plays an explanatory role, but one that is not cognitively mediated, or that it does not play any role, even if it is sometimes associated with other factors, such as probability, that may play a role in explaining some time biased preferences.

Drawing on Françoise Dastur’s suggestion that the event is a permanent possibility that shapes lived experience, but also, when it occurs, a distinctive temporal rupture, I argue that the initial weeks of the COVID-19 epidemic constitute an event, in her sense. Connecting this phenomenological point to literatures on the politics of temporality, I suggest that the distinction between event and normal experience maps to that between epidemic and endemic. Understanding some of the political and ethical erasures of death and debility (...) in COVID times can thus be mutually informed by phenomenological analysis. (shrink)

We explore the role of episodic imagining in explaining why people both differentially report that it seems to them in experience as though time robustly passes, and why they differentially report that they believe that time does in fact robustly pass. We empirically investigate two hypotheses, the differential vividness hypothesis, and the mental time travel hypothesis. According to each of these, the degree to which people vividly episodically imagine past/future states of affairs influences their tendency to report that it seems (...) to them as though time robustly passes and to judge that time does robustly pass. According to the former, a greater degree of vividness will tend to increase the extent to which people make such reports, while according to the latter, it will tend to decrease the extent to which people make such reports. We found weak evidence in favour of the former hypothesis. We reflect on the implications of this finding for theorising about such reports. (shrink)

A Significant percentage of the people outside their country of citizenship or residence who are unable to meet their basic needs on their own, and need international protection, do not fall under the definition set out in the UN Refugee Convention. This has led many - both academic commentators and activists - to call for a new, expanded refugee definition, preferably backed up by a new, binding, international convention. In earlier work I have resisted this call, arguing that there is (...) good reason to pick out a sub-stet of those in need of international aid - a set that largely, if not completely, corresponds to those picked out by the Refugee Convention - for special benefit and protection. However, even if Convention refugees are in some ways special, we are left with the question of what, if anything, is owed to those in need of aid who are not Convention refugees. In this chapter, I set out philosophical foundations for so-called complementary protection, and show how this may and should apply to people in need of international aid who are not Convention refugees.

In this chapter I focus on two problems facing immigration systems around the world, and Australia in particular. The topics addressed are chosen because each one involves important fundamental rights and because significant improvement in these areas is possible even if each state acts alone, without significant coordination with others. First, I examine refugee programmes, focussing specifically on the ‘two- tier’ refugee programmes pioneered by Australia with the introduction of Temporary Protection Visas by the Howard Government in 1999. Next, I (...) look at recent declines in refugee resettlement schemes from already stingy levels and, in relation to Australia in particular, I show how the tying of resettlement numbers to the number of affirmative asylum claims granted is both wrong- headed and counterproductive. The second area of immigration policy explored is family migration, another area where immigration systems around the world have been moving in the wrong direction, often via less than transparent administrative processes. Australia is no exception. While Australia’s family migration system is reasonably good on its face, in practice there are several factors which make the programme significantly less than satisfactory from the perspective of protecting the basic rights of migrants and, arguably more importantly, citizens. These problems can and should be fixed in straightforward ways, and since doing so would be more just, would have few— if any— significant negative consequences, and in fact would have a number of clear benefits, those changes should be made.

In this paper we examine how the use of robots in caring for elders can impact the meaningfulness of elders’ lives. We present a framework for understanding ‘meaningfulness in life’, and then apply that framework in discussing ways in which the use of robots to assist in activities of daily living can preserve, enhance or undermine the meaningfulness of elders’ lives. We conclude with a discussion of if and how having false beliefs about companion robots can affect meaningfulness in the (...) life of the person having those false beliefs. (shrink)

In 1926, Haldane published an essay titled 'On Being the Right Size' in which he argued that the structure, function, and behavior of an organism are strongly conditioned by the physical forces that exert the greatest impact at the scale at which it exists. This chapter puts Haldane’s insight to work in the context of contemporary cell and molecular biology. Owing to their minuscule size, cells and molecules are subject to very different forces than macroscopic organisms. In a sense, macroscopic (...) and microscopic entities inhabit different “worlds”: the former is ruled by gravity and inertia, whereas the latter is governed by Brownian motion. One implication is that we should be extremely skeptical of models and analogies that seek to explain properties of microscopic entities by appealing to properties of macroscopic ones. Unfortunately, this is precisely what the appeal to engineering metaphors in molecular biology attempts to do. Molecular biologists routinely resort to such metaphors because they are familiar and intuitively intelligible. But if our machines were the size of molecules it would be impossible for them to function the way they do. It follows that we should avoid distorting biological reality by construing it in engineering terms. In this chapter I examine four key metaphors in molecular biology – “genetic program,” “cellular circuitry,” “molecular machine,” and “molecular motor” – and I argue that their deficiencies derive from their neglect of scale. I also try to explain why many biologists today appear to have forgotten the importance of scale that Haldane drew attention to in his essay. I suggest that the reason has to do with the influence of Schrödinger’s argument in 'What is Life?' regarding the stability of the gene. (shrink)

The Physical Signature of Computation is the most “robust” mapping view that’s ever hit the market. It is impressive in its detail and the careful attention paid to its characterization of both the physical system and the formal computational description—a true service to the philosophical literature. The book promises a “unified account of artifact and biological computation,” but here’s where things take a turn: after handling artifacts, the Robust Mapping Account fades from view and the Mechanistic Account of Physical Computation (...) (in its neurocognitive form) emerges as the way to capture biological computation. To have a unified account, then, requires two distinct approaches to understanding the nature of physical computation. This raises questions about whether the Robust Mapping Account can be extended to neural computation, but most importantly, questions about the compatibly of these two views is questionable given the history of the Mechanistic Account and its underpinning framework.

What are the properties of composite objects, and how do the properties of composite objects and the properties of their proper parts relate to one another? The answers to these questions depend upon which view of composition one adopts. One view, which I call the orthodox view, is that composite objects are numerically distinct from their proper parts, individually and collectively. Another view, known as composition as identity, is that composite objects are numerically identical to their proper parts, taken together. (...) I argue that the orthodox view entails that the intuitive picture of composite objects and their properties that most accept is false. Not so for composition as identity. I also show that all of the available alternatives face serious difficulties. This puts composition as identity at an advantage over the orthodox view, at least when it comes to accounting for the properties of composite objects. (shrink)

An ongoing debate in the philosophy of action concerns the prevalence of moral luck: instances in which an agent’s moral responsibility is due, at least in part, to factors beyond his control. I point to a unique problem of moral luck for agents who depend upon Brain Computer Interfaces (BCIs) for bodily movement. BCIs may misrecognize a voluntarily formed distal intention (e.g., a plan to commit some illicit act in the future) as a control command to perform some overt behavior (...) now. If so, then BCI-agents may be deserving of punishment for the unlucky but foreseeable outcomes of their voluntarily formed plans, whereas standard counterparts who abandon their plans are not. However, it seems that the only relevant difference between BCI-agents and their standard counterparts is just a matter of luck. I briefly sketch different solutions that attempt to avoid this type of moral luck, while remaining agnostic on whether any succeeds. If none of these solutions succeeds, then there may be a unique type of moral luck that is unavoidable with respect to deserving punishment for certain BCI-mediated behaviors. (shrink)

Perhaps the most commonly discussed argument against the possibility of extended simples is the argument from heterogeneity. The argument states that, if extended simples are possible, then extended simples which exhibit intrinsic qualitative variation across space (or spacetime) are also possible [Premise 1]. But, the argument goes, it is impossible for an extended simple to exhibit intrinsic qualitative variation across space (or spacetime) [Premise 2]. Thus, extended simples are impossible. I argue that there is a serious problem with the argument (...) from heterogeneity: the best arguments in support of the first premise undermine support for the second. Thus, there appears to be no good reason to accept both premises. (shrink)

Three decades after Chalmers named it, the ‘hard problem’ remains. I suggest a parsimonious solution. Biological dynamic systems interact according to simple rules (while the environment provides simple constraints) and thus self-organize to become a new, more complex dynamic system at the next level. This spiral repeats several times generating a hierarchy of levels. A leap to the next level is frequently creative and surprising. From ants, themselves self-organized according to physical/chemical laws, may emerge an ant colony self-organized according to (...) eusocial laws. A dynamic system need not be material. A living language (immaterial) is a complex adaptive system. Body/brain are material but the next level of complexity, a psychological dynamic system, a thought, feeling, image or ideal, is less material. From several psychological dynamic systems emerges the next level, narrative (immaterial), and from multiple narratives emerges personality. Concrete evidence explains how an early narrative emerges from body-and-brain. Evidence also shows that personality emerges from narrative. Even an objective narrative captures subjectivity since the teller’s choice of content is subjective. I argue that the ‘stream-of-consciousness’ story (movie) you are currently telling yourself (watching) is your conscious experience, ‘what it is like’ for you to be conscious. Adriana Cavarero’s arguments support this. Each level of a hierarchy of dynamic systems must necessarily be homeostatic, at that level. McDowell et al. (2023: submitted, in revision) reported evidence that a dream (a narrative) supports personality homeostatically. Perhaps the evolutionary advantage of conscious experience, also a narrative, has always been that it too supports personality homeostatically. Personality and body/brain, a chimera of symbiotic life-forms, constitute interactionist duality. (shrink)

Assurance theories of testimony attempt to explain what is distinctive about testimony as a form of epistemic warrant or justification. The most characteristic assurance theories hold that a distinctive subclass of assertion (acts of “telling”) involves a real commitment given by the speaker to the listener, somewhat like a promise to the effect that what is asserted is true. This chapter sympathetically explains what is attractive about such theories: instead of treating testimony as essentially similar to any other kind of (...) evidence, they instead make testimonial warrant depend on essential features of the speech act of testimony as a social practice. One such feature is “buck-passing,” the phenomenon that when I am challenged to defend a belief I acquired through testimony, I may respond by referring to the source of my testimony (and thereby “passing the buck”) rather than providing direct evidence for the truth of the content of the belief. The chapter concludes by posing a serious challenge to assurance theories, namely that the social practice of assurance insufficiently ensures the truth of beliefs formed on the basis of testimony, and thereby fails a crucial epistemological test as a legitimate source of beliefs.

Problematic perceptions about race damage our society. These attitudes can seem impossible to overcome, but philosophers Dr Jennifer Mensch, at Western Sydney University in Australia, and Dr Michael Olson, at Marquette University in the US, beg to differ. They are compiling a collection of 18th-century philosophical and scientific texts that helped shape the way people saw race across the Western world, and were used to justify colonisation. They believe that by exposing these historical roots of racism, opportunities to improve societal (...) attitudes to race will become easier to identify. -/- This article was produced by Futurum Careers, a free online resource and magazine aimed at encouraging 14-19-year-olds worldwide to pursue careers in science, technology, engineering, maths and medicine (STEM), and social sciences, humanities and the arts for people and the economy (SHAPE).

Neural activity varies continually from moment to moment. Such temporal variability (TV) has been highlighted as a functionally specific brain property playing a fundamental role in cognition. We sought to investigate the mechanisms involved in TV changes between two basic behavioral states, namely having the eyes open (EO) or eyes closed (EC) in vivo in humans. To these ends we acquired BOLD fMRI, ASL, and [18F]-fluoro-deoxyglucose PET in a group of healthy participants (n = 15), along with BOLD fMRI and (...) [18F]-flumazenil PET in a separate group (n = 19). Focusing on an EO- vs EC-sensitive region in the occipital cortex (identified in an independent sample), we show that TV is constrained in the EO condition compared to EC. This reduction is correlated with an increase in energy consumption and with regional GABAA receptor density. This suggests that the modulation of TV by behavioral state involves an increase in overall neural activity that is related to an increased effect from GABAergic inhibition in addition to any excitatory changes. These findings contribute to our understanding of the mechanisms underlying activity variability in the human brain and its control. (shrink)

Neurovascular coupling (NVC), the transient regional hyperemia following the evoked neuronal responses, is the basis of blood oxygenation level-dependent techniques and is generally adopted across physiological conditions, including the intrinsic resting state. However, the possibility of neurovascular dissociations across physiological alterations is indicated in the literature. To examine the NVC stability across sleep–wake states, we used electroencephalography (EEG) as the index of neural activity and functional magnetic resonance imaging (fMRI) as the measure of cerebrovascular response. Eight healthy adults were recruited (...) for simultaneous EEG-fMRI recordings in nocturnal sleep. We compared the cross-modality (EEG vs. fMRI) consistency of functional indices (spectral amplitude and functional connectivity) among five states of wakefulness and sleep (state effect). We also segregated the brain into three main partitions (anterior, middle and posterior) for spatial assessments (regional effect). Significant state effects were found on δ, α and fMRI indices and regional effects on the α and fMRI indices. However, the cross-state EEG changes in spectral amplitude and functional connectivity did not consistently match the changes in the fMRI indices across sleep–wake states. In spectral amplitude, the δ band peaked at the N3 stage for all brain regions, while the fMRI fluctuation amplitude peaked at the N2 stage in the central and posterior regions. In regional connectivity, the inter-hemispheric connectivity of the δ band peaked at the N3 stage for all regions, but the bilateral fMRI connectivity showed the state changes in the anterior and central regions. The cross-modality inconsistencies across sleep–wake states provided preliminary evidence that the neurovascular relationship may not change in a linear consistency during NREM sleep. Thus, caution shall be exercised when applying the NVC presumption to investigating sleep/wake transitions, even among healthy young adults. (shrink)

Objective Manic and depressive phases of bipolar disorder (BD) show opposite psychomotor symptoms. Neuronally, these may depend on altered relationships between sensorimotor network (SMN) and subcortical structures. The study aimed to investigate the functional relationships of SMN with substantia nigra (SN) and raphe nuclei (RN) via subcortical-cortical loops, and their alteration in bipolar mania and depression, as characterized by psychomotor excitation and inhibition. -/- Method In this resting-state functional magnetic resonance imaging (fMRI) study on healthy (n = 67) and BD (...) patients (n = 100), (1) functional connectivity (FC) between thalamus and SMN was calculated and correlated with FC from SN or RN to basal ganglia (BG)/thalamus in healthy; (2) using an a-priori-driven approach, thalamus-SMN FC, SN-BG/thalamus FC, and RN-BG/thalamus FC were compared between healthy and BD, focusing on manic (n = 34) and inhibited depressed (n = 21) patients. -/- Results (1) In healthy, the thalamus-SMN FC showed a quadratic correlation with SN-BG/thalamus FC and a linear negative correlation with RN-BG/thalamus FC. Accordingly, the SN-related FC appears to enable the thalamus-SMN coupling, while the RN-related FC affects it favoring anti-correlation. (2) In BD, mania showed an increase in thalamus-SMN FC toward positive values (ie, thalamus-SMN abnormal coupling) paralleled by reduction of RN-BG/thalamus FC. By contrast, inhibited depression showed a decrease in thalamus-SMN FC toward around-zero values (ie, thalamus-SMN disconnection) paralleled by reduction of SN-BG/thalamus FC (and RN-BG/thalamus FC). The results were replicated in independent HC and BD datasets. -/- Conclusions These findings suggest an abnormal relationship of SMN with neurotransmitters-related areas via subcortical-cortical loops in mania and inhibited depression, finally resulting in psychomotor alterations.

The neurotransmitters GABA and glutamate have been suggested to play a role in Major Depressive Disorder (MDD) through an imbalance between cortical inhibition and excitation. This effect has been highlighted in higher brain areas, such as the prefrontal cortex, but has also been posited in basic sensory cortices. Based on this, magnetic resonance spectroscopy (MRS) was used to investigate potential changes to GABA+ and glutamate+glutamine (Glx) concentrations within the occipital cortex in MDD patients (n = 25) and healthy controls (n (...) = 25). No difference in occipital GABA+ or Glx concentrations, nor in the GABA+/Glx ratio, was found between groups. An analysis of an extended MDD patient and unmatched control dataset (n = 90) found no correlation between metabolite concentrations and depressive symptoms. These results were integrated with prior studies through metabolite-specific meta-analyses, revealing no difference in occipital GABA and Glx concentrations between patients and controls. An effect of publication year on GABA group differences was found, suggesting that previously reported results may have been artifacts of measurement accuracy. Taken together, our results suggest that, contrary to some prior reports, MRS measurements of occipital GABA and Glx do not differ between MDD patients and controls. (shrink)
