The aim of this paper is threefold. Firstly, §1 and §2 introduce the novel concept logical akrasia by analogy to epistemic akrasia. If successful, the initial sections will draw attention to an interesting akratic phenomenon which has not received much attention in the literature on akrasia (although it has been discussed by logicians in different terms). Secondly, §3 and §4 present a dilemma related to logical akrasia. From a case involving the consistency of Peano Arithmetic and Gödel’s Second Incompleteness Theorem (...) it’s shown that either we must be agnostic about the consistency of Peano Arithmetic or akratic in our arithmetical theorizing. If successful, these sections will underscore the pertinence and persistence of akrasia in arithmetic (by appeal to Gödel’s seminal work). Thirdly, §5 concludes by suggesting a way of translating the dilemma of arithmetical akrasia into a case of regular epistemic akrasia; and further how one might try to escape the dilemma when it’s framed this way.

The machine conception of the organism (MCO) is one of the most pervasive notions in modern biology. However, it has not yet received much attention by philosophers of biology. The MCO has its origins in Cartesian natural philosophy, and it is based on the metaphorical redescription of the organism as a machine. In this paper I argue that although organisms and machines resemble each other in some basic respects, they are actually very different kinds of systems. I submit that the (...) most significant difference between organisms and machines is that the former are intrinsically purposive whereas the latter are extrinsically purposive. Using this distinction as a starting point, I discuss a wide range of dissimilarities between organisms and machines that collectively lay bare the inadequacy of the MCO as a general theory of living systems. To account for the MCO’s prevalence in biology, I distinguish between its theoretical, heuristic, and rhetorical functions. I explain why the MCO is valuable when it is employed heuristically but not theoretically, and finally I illustrate the serious problems that arise from the rhetorical appeal to the MCO. (shrink)

The mental health crisis and loneliness epidemic have sparked a growing interest in leveraging artificial intelligence (AI) and chatbots as a potential solution. This report examines the benefits and risks of incorporating chatbots in mental health treatment. AI is used for mental health diagnosis and treatment decision-making and to train therapists on virtual patients. Chatbots are employed as always-available intermediaries with therapists, flagging symptoms for human intervention. But chatbots are also sold as stand-alone virtual therapists or as friends and lovers. (...) There is evidence that these uses of AI and chatbots can provide better quality service, improve accessibility, and lower costs. The systems can reduce the stigma and shame of sharing their problems and leverage a mass of biometric and behavioral data to supplement self-reports. As the systems' intelligence rapidly improves, they will need to be rigorously tested for the accuracy and precision of their diagnoses and the quality of their interactions with patients. As chatbots become indistinguishable from humans and leverage their superhuman capacity to detect affect and draw on knowledge of a patient’s life, patients will be drawn to attribute personality to and relationship with the chatbot. Consequently, it will be essential to study what the “therapeutic alliance” with an actual human counselor provides and the risks of patients attributing such a relationship to a one-sided or “parasocial” relationship.

‘Gender disappointment’ is regularly reported by those whose child’s sex does not match the sex that they, the parent, desired. With symptoms ranging from mere fleeting sadness to documented cases of serious depression, alienation from one’s child, and emotional suffering, it is clear that so-called ‘gender disappointment’ is a serious issue, that has, as yet, seen little philosophical attention (though see Hendl and Browne 2020). In this chapter I explore gender disappointment, not from the perspective of a parent who ended (...) up with the child of the wrong sex at birth, but rather, from the perspective of a different kind of gender disappointment: the transgender person who grew up and only then disappointed their parents by turning out to be the ‘wrong’ gender. This perspective, I argue, reveals a great deal about the shared gender essentialism at the heart of patriarchal and cissexist ideology. Moreover, I will argue that it reveals the underlying propertarian relationship of parents to their children under contemporary capitalism – a troubling relationship that legitimates the treatment of children as objects to be designed and controlled as commodities at the whims of parents. In this way I disagree with Whyman when he writes that “a preference for having a child of one sex over the other should be considered one of those irrational things of which some sense can nevertheless be made – like aesthetic taste” (Whyman 2021, 113-114). I argue, to the contrary, that the desire for a child of one particular gender is not akin to a mere unproblematic aesthetic preference. Instead, and following the rich feminist tradition of thinking about the patriarchal origins of sexual desire, I argue that we must see these desires as troubling reflections of dominant patriarchal and cissexist ideology, underwritten by a particular neoliberal capitalist mode of production. Moreover, we can seek to change those desires. (shrink)

Glucagon-like peptide-1 (GLP-1) receptor agonists, such as semaglutide, and dual GLP-1 and glucose-dependent insulinotropic polypeptide (GIP) receptor agonists, such as tirzepatide, have been found to be effective for treating obesity and diabetes, significantly reducing weight and the risk or predicted risk of adverse cardiovascular events. There is a global shortage of these medications that could last several years and raises questions about how limited supplies should be allocated. We propose a fair-allocation framework that enables evaluation of the ethics of current (...) practices and could guide governments, professional societies, and physicians in allocation decisions.

Objectives Practitioners in contemplative traditions commonly report experiencing an awareness that is distinct from sensory objects, thoughts, and emotions (“awareness itself”). They also report experiences of a void or underlying silence that is closely associated with this awareness. Subjects who carry out the Headless Way exercises frequently report an experience of emptiness or void at the same time as other contents (void-like experiences). The goals of this study were to (1) assess the reliability of these methods in eliciting the recognition (...) of awareness and void-like experiences in participants who had no prior exposure to these techniques, (2) investigate the prevalence of these experiences in these tasks, and (3) to differentiate these experiences from closely related and potential precursor experiences. -/- Method Twenty adults participated in in-depth individual interviews in which they were guided through the Headless Way exercises. A thematic analysis was conducted on the interview transcripts. -/- Results Twelve of the participants reported a void-like experience, and five participants reported an experience of awareness itself. These experiences were respectively categorized as subsets of the more general categories of perceptual absences and the sense of not being person-like. Another novel finding was the real-time reports of awareness and void-like experiences during the exercises. -/- Conclusions Our findings provide preliminary evidence that the Headless Way exercises can effectively induce experiences of emptiness and awareness in participants without prior experience. The findings suggest that such experiences can be elicited outside of a traditional meditation context, including in non-meditators. Furthermore, the experience of not being person-like and of perceptual absences may be precursors and more general forms of recognizing awareness itself and the void-like nature of the mind.

In their Why Machines Will Never Rule the World, Landgrebe and Smith (2023) argue that it is impossible for artificial general intelligence (AGI) to succeed, on the grounds that it is impossible to perfectly model or emulate the “complex” “human neurocognitive system”. However, they do not show that it is logically impossible; they only show that it is practically impossible using current mathematical techniques. Nor do they prove that there could not be any other kinds of theories than those in (...) current use. Even if perfect theories were impossible or unlikely, perfection may not be needed and may even be unhelpful. (shrink)

"Why are there 'transsexuals' but not 'transracials'?" "Why is there an accepted way to change sex, but not to change race?" I have repeatedly heard these questions from theorists puzzled by the phenomenon of transsexuality. Feminist thinkers, in particular, often seem taken aback that in the case of category switching the possibilities appear to be so different. Behind the question is sometimes an implicit concern: Does not the (hypothetical or real) example of individual “transracialism” seem politically troubling? And, if it (...) is, does not the case of transsexuality merit equivalent critique? Or, conversely, if one accepts transsexuals as people with legitimate demands (e.g., on medical resources or single-sex spaces), then would one not also be committed to accepting the putative transracial in analogous ways? Understanding the ontological constraints and possibilities with regard to transforming one’s identity is, I suggest, a project that should accompany ethical evaluation of those transformations. Under what circumstances is it (un)ethical to leave behind a gender or racial group with which one has once been affiliated? This question is, again, especially pressing for radical thinkers who endorse the claims that race and gender taxonomies are internally hierarchical and constituted through relations of oppression, domination, and normalization. Changing one’s identity under these circumstances will surely always be linked, however tenuously, to consideration of the larger political and cultural milieu in which such changes are advantageous or disadvantageous, complicit with oppressive norms and/or resistant to them. To illuminate these larger questions, in this paper, I first provide three examples of the analogy thesis in feminist thinking about race and sex change, each of which draws ethical conclusions about individual motivation, political strategy, or public policy, premised on the assumption that race and sex change are equivalent phenomena. None of these accounts consider the genealogy of each category as significant to contemporary possibilities. I next offer a descriptive analysis that highlights different norms at play in contemporary North American understandings: Sex–gender, I argue, is essentialized as a property of the individual’s body, while race is essentialized with reference to both the body and ancestry. This analysis, I conclude, shows politically significant disanalogies between the categories, and reveals the importance of genealogical accounts of race and sex in thinking ethically about changing ourselves.

Perception involves the processing of content or information about the world. In what form is this content represented? I argue that perception is widely compositional. The perceptual system represents many stimulus features (including shape, orientation, and motion) in terms of combinations of other features (such as shape parts, slant and tilt, common and residual motion vectors). But compositionality can take a variety of forms. The ways in which perceptual representations compose are markedly different from the ways in which sentences or (...) thoughts are thought to be composed. I suggest that the thesis that perception is compositional is not itself a concrete hypothesis with specific predictions; rather it affords a productive framework for developing and evaluating specific empirical hypotheses about the form and content of perceptual representations. The question is not just whether perception is compositional, but how. Answering this latter question can provide fundamental insights into perception. (shrink)

Memes are a prominent example of a kind of digital artifact. It is widely agreed that an integral component of meme-making is the way in which it makes use of other existing material. In this paper, I examine three different ways of understanding this making use of. First, it has been seen in economic terms, as a kind of poaching. Secondly, the cultural concept of (re)appropriation has been deployed. Finally, Lévi-Strauss’s notion of bricolage is often mentioned. I argue that despite (...) some interesting insights deriving from the first two approaches, it is the third that gives the most comprehensive and interesting take on meme-making. (shrink)

Epistemic internalism, by stressing the indispensability of the subject’s perspective, strikes many as plausible at first blush. However, many people have tended to reject the position because certain kinds of beliefs have been thought to pose special problems for epistemic internalism. For example, internalists tend to hold that so long as a justifier is available to the subject either immediately or upon introspection, it can serve to justify beliefs. Many have thought it obvious that no such view can be correct, (...) as it has been alleged that internalism cannot account for the possibility of the justification of beliefs stored in memory. -/- My aim in this paper is to offer a response that explains how memory justification is possible in a way that is consistent with epistemic internalism and an awareness condition on justification. Specifically, I will explore the plausibility of various options open to internalists, including both foundationalist and non-foundationalist approaches to the structure of justification. I intend to show that despite other difficult challenges that epistemic internalism might face, memory belief poses no special problems that the resources of internalism cannot adequately address.

The JTB definition of knowledge has been shown by Gettier to be incomplete: its three conditions are necessary for knowledge, but not sufficient. We argue that the JTB definition can be completed with a very simple fourth condition, namely that the justification for the belief in p must be sufficient to exclude ¬p. It is shown that the resulting JTB+S definition solves the Gettier problem.

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)

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)

Here we focus on two questions: What is the proper semantics for deontic modal expressions in English? And what is the connection between true deontic modal statements and normative reasons? Our contribution towards thinking about the first, which makes up the bulk of our paper, considers a representative sample of recent challenges to a Kratzer-style formal semantics for modal expressions, as well as the rival views—Fabrizio Cariani’s contrastivism, John MacFarlane’s relativism, and Mark Schroeder’s ambiguity theory—those challenges are thought to motivate. (...) These include the Professor Procrastinate challenge to Inheritance (the principle that ‘If ought p and p entails q, then ought q), as well as Parfit’s miners puzzle regarding information-sensitive deontic modals. Here we argue that a Kratzer-style view is able to meet all of the challenges we’ll consider. In addition, we’ll identify challenges for each of those rival views. Our overall conclusion is that a Kratzer-style semantics remains the one to beat. With this assumption in place, we then ask how we should understand the relationship between true deontic modal statements and normative reasons. Should, for example, we hold that the truth of such a statement entails the existence of a normative reason for some agent to comply? Here we argue that, in many cases, acceptance of Kratzer’s semantics for deontic modals leaves open for substantive normative theorizing the question of whether an agent has a normative reason to comply with what she ought to do.

The first aim of the paper is to show that under certain conditions generative syntax can be made suitable for Montague semantics, based on his type logic. One of the conditions is to make branching in the so-called X-bar syntax strictly binary, This makes it possible to provide an adequate semantics for Noun Phrases by taking them as referring to sets of collections of sets of entities ( type <ett,t>) rather than to sets of sets of entities (ett).

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.

Etic theorizing uses the theorist’s social notions to theorize about their subject. This theorist may claim that Genghis Khan was a war criminal even though his actions predate the enactment of the Geneva Conventions. Brian Epstein considers a modal etic theorist who claims that Genghis Khan would have been a war criminal even if the Geneva Conventions were never enacted. Epstein argues that this has metaphysical import: it requires postulating a novel metaphysical notion of “anchoring”. Drawing from some familiar issues (...) in modal actualism, I argue that modal etic theorizing does not support this postulate. But it does suggest a distinctive kind of modality at work in social reality. (shrink)

The paper provides a critical review of the debate on the foundations of Computer Ethics (CE). Starting from a discussion of Moor’s classic interpretation of the need for CE caused by a policy and conceptual vacuum, five positions in the literature are identified and discussed: the “no resolution approach”, according to which CE can have no foundation; the professional approach, according to which CE is solely a professional ethics; the radical approach, according to which CE deals with absolutely unique issues, (...) in need of a unique approach; the conservative approach, according to which CE is only a particular applied ethics, discussing new species of traditional moral issues; and the innovative approach, according to which theoretical CE can expand the metaethical discourse with a substantially new perspective. In the course of the analysis, it is argued that, although CE issues are not uncontroversially unique, they are sufficiently novel to render inadequate the adoption of standard macroethics, such as Utilitarianism and Deontologism, as the foundation of CE and hence to prompt the search for a robust ethical theory. Information Ethics (IE) is proposed for that theory, as the satisfactory foundation for CE. IE is characterised as a biologically unbiased extension of environmental ethics, based on the concepts of information object/infosphere/entropy rather than life/ecosystem/pain. In light of the discussion provided in this paper, it is suggested that CE is worthy of independent study because it requires its own application-specific knowledge and is capable of supporting a methodological foundation, IE.

A Wittgensteinian Way with Paradoxes examines how some of the classic philosophical paradoxes that have so puzzled philosophers over the centuries can be dissolved. Read argues that paradoxes such as the Sorites, Russell’s Paradox and the paradoxes of time travel do not, in fact, need to be solved. Rather, using a resolute Wittgensteinian ‘therapeutic’ method, the book explores how virtually all apparent philosophical paradoxes can be diagnosed and dissolved through examining their conditions of arising; to loosen their grip and therapeutically (...) liberate those philosophers suffering from them (including oneself). The book contrasts such paradoxes with real, ‘lived paradoxes’: paradoxes that are genuinely experienced outside of the philosopher’s study, in everyday life. Thus Read explores instances of lived paradox (such as paradoxes of self-hatred and of denial of other humans’ humanity) and the harm they can cause, psychically, morally or politically. These lived paradoxes, he argues, sometimes cannot be dissolved using a Wittgensteinian treatment. Moreover, in some cases they do not need to be: for some, such as the paradoxical practices of Zen Buddhism (and indeed of Wittgenstein himself), can in fact be beneficial. The book shows how, once philosophers’ paradoxes have been exorcized, real lived paradoxes can be given their due. (shrink)

The Welfare-Funded Sex Doula Programme is a proposed sexual needs service that advances the sexual citizenship of disabled people by providing specially trained ‘sex doulas’ to meet the various, often complex, sexual needs of disabled people. Conceived as providing disabled individuals with practical sexual support services, the role of the sex doula includes advocacy, counselling, therapy, and practical relief from sexual tension. The programme constitutes a robust, comprehensive, and theoretically cohesive welfare service that seeks to provision access to sexual citizenship (...) for disabled people. -/- Grounded in Aristotelian concepts of flourishing, the programme identifies sexual citizenship as a fundamental basic need and seeks to ensure that disabled people have the opportunity to achieve the same level of sexuality as able-bodied people. Work advancing the programme includes both philosophical and theoretical arguments showing how the programme is justified under several moral frameworks, and claims made therein have resulted in velitation in the literature regarding the potential of such a programme to violate individuals’ negative rights.

Globalization is resulting in complex decisions by businesses as to where and what to produce, while free trade is resulting in a greater menu of choices for consumers, often with the blending of products and goods from various cultures, called ‘glocalization.’ This paper reviews the theories and practices behind these current happenings, which are each economic, politicaleconomic, institutional, and sociological, first by looking at the supply side of why certain countries produce the goods that they do, and then at the (...) demand side, why consumers have particular, cultural tastes and preferences for goods. It also proffers theories to explain firm location and that of intra-industry trade. This occus when countries trade similar products rather than differentiating, as economic theory would suggest. After reviewing the literature, through numerous examples of political-economy and culture, it argues somewhat normatively that differences in culture and goods are a strength to the world community, and that globalization in the end will not likely result in a singular global culture with a uniformity of exactly identical economic goods anytime in the near future.

One challenge to the rationality of religious commitment has it that faith is unreasonable because it involves believing on insufficient evidence. However, this challenge and influential attempts to reply depend on assumptions about what it is to have faith that are open to question. I distinguish between three conceptions of faith each of which can claim some plausible grounding in the Judaeo-Christian tradition. Questions about the rationality or justification of religious commitment and the extent of compatibility with doubt look different (...) on accounts of faith in which trust or hope, rather than belief, are the primary basis for the commitments. On such accounts, while the person of faith has a stake in the truth of the content, practical as well as epistemic considerations can legitimately figure in normative appraisals. Trust and hope can be appropriate in situations of recognized risk, need not involve self-deception, and are compatible with the idea that one's purely epistemic opinions should be responsive only to evidence.Send article to KindleTo send this article to your Kindle, first ensure [email protected] is added to your Approved Personal Document E-mail List under your Personal Document Settings on the Manage Your Content and Devices page of your Amazon account.

For decades scholars thought they knew Hume's position on the existence of causes and objects he was a sceptic. However, this received view has been thrown into question by the `new readings of Hume as a sceptical realist. For philosophers, students of philosophy and others interested in theories of causation and their history, The New Hume Debate is the first book to fully document the most influential contemporary readings of Hume's work. Throughout, the volume brings the debate beyond textual issues (...) in Hume to contemporary philosophical issues concerning causation and knowledge of the external world and issues in the history of philosophy, offering the reader a model for scholarly debate. This revised paperback edition includes three new chapters by Janet Broughton, Peter Kail and Peter Millican. Contributors: Kenneth A. Richman, Barry Stroud, Galen Strawson, Kenneth P. Winkler, John P. Wright, Simon Blackburn, Edward Craig, Martin Bell, Daniel Flage, Anne Jaap Jacobson, Rupert Read, Janet Broughton, Peter Millican, Peter Kail. (shrink)

We develop and apply a multi-dimensional account of explanatory depth towards a comparative analysis of inflationary and bouncing paradigms in primordial cosmology. Our analysis builds on earlier work due to Azhar and Loeb (2021) that establishes initial conditions fine-tuning as a dimension of explanatory depth relevant to debates in contemporary cosmology. We propose dynamical fine-tuning and autonomy as two further dimensions of depth in the context of problems with instability and trans-Planckian modes that afflict bouncing and inflationary approaches respectively. In (...) the context of the latter issue, we argue that the recently formulated trans-Planckian censorship conjecture leads to a trade-off for inflationary models between dynamical fine-tuning and autonomy. We conclude with the suggestion that explanatory preference with regard to the different dimensions of depth is best understood in terms of differing attitudes towards heuristics for future model building.

Decision-making under normative uncertainty requires an agent to aggregate the assessments of options given by rival normative theories into a single assessment that tells her what to do in light of her uncertainty. But what if the assessments of rival theories differ not just in their content but in their structure -- e.g., some are merely ordinal while others are cardinal? This paper describes and evaluates three general approaches to this "problem of structural diversity": structural enrichment, structural depletion, and multi-stage (...) aggregation. All three approaches have notable drawbacks, but I tentatively defend multi-stage aggregation as least bad of the three. (shrink)

An analysis of the identity issues involved in facial allograft transplantation is provided in this paper. The identity issues involved in organ transplantation in general, under both theoretical accounts of personal identity and subjective accounts provided by organ recipients, are examined. It is argued that the identity issues involved in facial allograft transplantation are similar to those involved in organ transplantation in general, but much stronger because the face is so closely linked with personal identity. Recipients of facial allograft transplantation (...) have the potential to feel that their identity is a mix between their own and the donor’s, and the donor’s family is potentially likely to feel that their loved one ‘‘lives on’’. It is also argued that facial allograft transplantation allows the recipients to regain an identity, because they can now be seen in the social world. Moreover, they may regain expressivity, allowing for them to be seen even more by others, and to regain an identity to an even greater extent. Informing both recipients and donors about the role that identity plays in facial allograft transplantation could enhance the consent process for facial allograft transplantation and donation.

This was a class handout that I turned into a publication. As its title indicates, it's about the relation (or non-relation) of (ethical) cultural relativism to tolerance.

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)

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)

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)

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)

Precision Medicine is driven by the idea that the rapidly increasing range of relatively cheap and efficient self-tracking devices make it feasible to collect multiple kinds of phenotypic data. Advocates of N = 1 research emphasize the countless opportunities personal data provide for optimizing individual health. At the same time, using biomarker data for lifestyle interventions has shown to entail complex challenges. In this paper, we argue that researchers in the field of precision medicine need to address the performative dimension (...) of collecting data. We propose the fun-house mirror as a metaphor for the use of personal health data; each health data source yields a particular type of image that can be regarded as a ‘data mirror’ that is by definition specific and skewed. This requires competence on the part of individuals to adequately interpret the images thus provided. (shrink)

It is now well-known that Newton–Cartan theory is the correct geometrical setting for modelling the quantum Hall effect. In addition, in recent years edge modes for the Newton–Cartan quantum Hall effect have been derived. However, the existence of these edge modes has, as of yet, been derived using only orthodox methodologies involving the breaking of gauge-invariance; it would be preferable to derive the existence of such edge modes in a gauge-invariant manner. In this article, we employ recent work by Donnelly (...) and Freidel in order to accomplish exactly this task. Our results agree with known physics, but afford greater conceptual insight into the existence of these edge modes: in particular, they connect them to subtle aspects of Newton–Cartan geometry and pave the way for further applications of Newton–Cartan theory in condensed matter physics.

Much problem solving and learning research in math and science has focused on formal representations. Recently researchers have documented the use of unschooled strategies for solving daily problems -- informal strategies which can be as effective, and sometimes as sophisticated, as school-taught formalisms. Our research focuses on how formal and informal strategies interact in the process of doing and learning mathematics. We found that combining informal and formal strategies is more effective than single strategies. We provide a theoretical account of (...) this multiple strategy effect and have begun to formulate this theory in an ACT-R computer model. We show why students may reach common impasses in the use of written algebra, and how subsequent or concurrent use of informal strategies leads to better problem-solving performance. Formal strategies facilitate computation because of their abstract and syntactic nature; however, abstraction can lead to nonsensical interpretations and conceptual errors. Reapplying the formal strategy will not repair such errors; switching to an informal one may. We explain the multiple strategy effect as a complementary relationship between the computational efficiency of formal strategies and the sense-making function of informal strategies. (shrink)

The origin and development of consciousness is poorly understood. Although it is clearly a naturalistic phenomenon evolved through Darwinian evolution, explaining it in terms of physicochemical, neural, or symbolic mechanisms remains elusive. Here I propose that two steps had to be taken in its evolution. First, living systems evolved an intrinsic goal-directedness by internalizing Darwinian fitness as a self-estimated fitness. The self-estimated fitness participates in a feedback loop that effectively produces intrinsic meaning in the organism. Second, animals with advanced nervous (...) systems evolved a special form of communication that modifies the way each partner estimates fitness. The resulting change in intrinsic meaning is experienced subjectively as a primary form of consciousness. This primary form is subsequently used to generate, partly through internalized dialogue, more complex forms of consciousness, such as consciousness of the natural and social worlds, consciousness of the self, and language-dependent forms of consciousness. An updated version of the theory in this paper can be found as Chapter 12 ('Consciousness') in my book 'The estimator theory of life and mind: how agency and consciousness can emerge', see VANTET-8 at philpapers .

Although there is no consensus about the exact span of time that corresponds to the American Enlightenment, it is safe to say that it occurred during the eighteenth century among thinkers in British North America and the early United States and was inspired by the ideas of the British and French Enlightenments. Based on the metaphor of bringing light to the Dark Age, the Age of the Enlightenment (Siècle des lumières in French and Aufklärung in German) shifted allegiances away from (...) absolute authority, whether religious or political, to more skeptical and optimistic attitudes about human nature, religion and politics. In the American context, thinkers such as Thomas Paine, James Madison, Thomas Jefferson, John Adams and Benjamin Franklin invented and adopted revolutionary ideas about scientific rationality, religious toleration and experimental political organization—ideas that would have far-reaching effects on the development of the fledgling nation. Some coupled science and religion in the notion of deism; others asserted the natural rights of man in the anti-authoritarian doctrine of liberalism; and still others touted the importance of cultivating virtue, enlightened leadership and community in early forms of republican thinking. At least six ideas came to punctuate American Enlightenment thinking: deism, liberalism, republicanism, conservatism, toleration and scientific progress. Many of these were shared with European Enlightenment thinkers, but in some instances took a uniquely American form. (shrink)

Is the overall value of a world just the sum of values contributed by each value-bearing entity in that world? Additively separable axiologies (like total utilitarianism, prioritarianism, and critical level views) say 'yes', but non-additive axiologies (like average utilitarianism, rank-discounted utilitarianism, and variable value views) say 'no'. This distinction is practically important: additive axiologies support 'arguments from astronomical scale' which suggest (among other things) that it is overwhelmingly important for humanity to avoid premature extinction and ensure the existence of a (...) large future population, while non-additive axiologies need not. We show, however, that when there is a large enough 'background population' unaffected by our choices, a wide range of non-additive axiologies converge in their implications with some additive axiology -- for instance, average utilitarianism converges to critical-level utilitarianism and various egalitarian theories converge to prioritiarianism. We further argue that real-world background populations may be large enough to make these limit results practically significant. This means that arguments from astronomical scale, and other arguments in practical ethics that seem to presuppose additive separability, may be truth-preserving in practice whether or not we accept additive separability as a basic axiological principle.

Time as the key to a theory of everything became recently a renewed topic in scientific literature. Social constructivism applied to physics abandons the inevitable essentials of nature. It adopts uncertainty in the scope of the existential activity of scientific research. We have enlightened the deep role of social constructivism of the predetermined Newtonian time and space notions in natural sciences. Despite its incompatibility with determinism governing the Newtonian mechanics, randomness and entropy are inevitable when negative localized energy is transformed (...) into spatially dissipative heat. In sharp contrast to the Newtonian notion, social constructivism makes room for the temporal twin of cyclic conservation and pseudo-linearly structural evolution both reconciling mechanical order and thermodynamic chaos in Leibnizian space-time. In the broad scope of natural sciences this triad nature of time produces a multiple reality and gives appropriate answers on virtual physical paradoxes. (shrink)

Niettegenstaande de tendens van het failliet van het multiculturalisme is multiculturele dialoog niet weg te denken in een zich globaliserende wereld. Taylor, Gadamer, Honneth en Kymlicka hebben een bijdrage geleverd op het vlak van de erkenning van identiteit, respect en waardering van verschil. Wij voeren het argument aan dat bovenstaande auteurs niet ontsnappen aan het postmodernistisch dilemma van zelfautonomie en slachtofferschap. Dit komt doordat zij in hun rationale vertrekken van het afzonderlijke subject en deze situeren in een ruimte-tijd waarin de (...) tijd slechts een historische rol heeft en de ruimte geen actieve rol speelt. Tegenover deze uitvloeisels van het postmodern denken stellen wij het eco-communau-tarisme. Vanuit de vaststelling dat het individu denkt, spreek en handelt in de context van zijn taal en cultuur en dus vanuit zijn gemeenschap, situeren wij dit subject en de gemeenschap tevens in een particulier territorium of het ecotoop. Door middel van Hacking’s sociaal constructivisme, het Leibniziaanse meerwereldenbeeld en het biologische paradigma als nieuw denkkader, structureren wij de gemeenschap volgens een cyclisch en een lineair tijdverloop. Het cyclische waarborgt de traditie van een gemeenschap, het lineaire doet de gemeenschap evolueren naar een moreel betere toekomst en heeft een transcendent statuut. Het eco-communautarisme biedt het kader voor een kwalitatieve evolutie van individuen en gemeenschappen. Het normerend aspect hiervan is de pluriforme en multiculturele dialoog. (shrink)

The problem considered in this chapter emerges from the tension we find when looking at the design and architecture of chatbots on the one hand and their conversational aptitude on the other. In the way that LLM chatbots are designed and built, we have good reason to suppose they don't possess second-order capacities such as intention, belief or knowledge. Yet theories of conversation make great use of second-order capacities of speakers and their audiences to explain how aspects of interaction succeed. (...) As we can all bear witness to now though, at the point of use chatbots appear capable of performing language tasks at a level close to that of humans. This creates a tension when we consider something like, for example, the classic Gricean theory of implicature. On a broad summary of this type of account, to utter p and implicate q requires the reflexive occurrence of an audience supposing a speaker believes that q, and the speaker believing that their audience can determine they believe it when they utter p. So taken at face value, if a chatbot doesn’t have the capacity for belief, then either in their role as speaker or audience, they would not seem capable of either generating or comprehending implicatures. Yet on the surface it does seem that chatbots are capable of dealing with (some) implicatures, and as such it raises questions about how we should then correlate this with what we think occurs in cases of implicature with chatbots.

This paper argues that the current discourse on epistemic injustice in social epistemology itself perpetuates epistemic injustice, namely hermeneutic injustice with regards to class and classism. The main reason is that debates on epistemic injustice have foremost focussed on issues related to gender, race, and disability while mostly ignoring class issues. I suggest that this is due to (largely unwarranted) fears about looming class reductionism. More importantly, this is omission is not innocuous, but problematic insofar as it has an unlikely (...) ally in neoliberal propaganda which features as one main goal stifling class consciousness. While this “allyship” is unwitting, this presents grounds for the discourse of epistemic injustice to consider re-centring class issues and classism. (shrink)
