Speakers of many languages prefer allocentric frames of reference (FoRs) when talking about small‐scale space, using words like “east” or “downhill.” Ethnographic work has suggested that this preference is also reflected in how such speakers gesture. Here, we investigate this possibility with a field experiment in Juchitán, Mexico. In Juchitán, a preferentially allocentric language (Isthmus Zapotec) coexists with a preferentially egocentric one (Spanish). Using a novel task, we elicited spontaneous co‐speech gestures about small‐scale motion events (e.g., toppling blocks) in Zapotec‐dominant (...) speakers and in balanced Zapotec‐Spanish bilinguals. Consistent with prior claims, speakers’ spontaneous gestures reliably reflected either an egocentric or allocentric FoR. The use of the egocentric FoR was predicted—not by speakers’ dominant language or the language they used in the task—but by mastery of words for “right” and “left,” as well as by properties of the event they were describing. Additionally, use of the egocentric FoR in gesture predicted its use in a separate nonlinguistic memory task, suggesting a cohesive cognitive style. Our results show that the use of spatial FoRs in gesture is pervasive, systematic, and shaped by several factors. Spatial gestures, like other forms of spatial conceptualization, are thus best understood within broader ecologies of communication and cognition. (shrink)

What enables individually simple insects like ants to act with such precision and purpose as a group? How do trillions of individual neurons produce something as extraordinarily complex as consciousness? What is it that guides self-organizing structures like the immune system, the World Wide Web, the global economy, and the human genome? These are just a few of the fascinating and elusive questions that the science of complexity seeks to answer. In this remarkably accessible and companionable book, leading complex systems (...) scientist Melanie Mitchell provides an intimate, detailed tour of the sciences of complexity, a broad set of efforts that seek to explain how large-scale complex, organized, and adaptive behavior can emerge from simple interactions among myriad individuals. Comprehending such systems requires a wholly new approach, one that goes beyond traditional scientific reductionism and that re-maps long-standing disciplinary boundaries. Based on her work at the Santa Fe Institute and drawing on its interdisciplinary strategies, Mitchell brings clarity to the workings of complexity across a broad range of biological, technological, and social phenomena, seeking out the general principles or laws that apply to all of them. She explores as well the relationship between complexity and evolution, artificial intelligence, computation, genetics, information processing, and many other fields. Richly illustrated and vividly written, Complexity : A Guided Tour offers a comprehensive and eminently comprehensible overview of the ideas underlying complex systems science, the current research at the forefront of this field, and the prospects for the field's contribution to solving some of the most important scientific questions of our time.

Neither art criticism nor a scholar’s monograph on an artist, Jean-François Lyotard’s Sam Francis: Lesson of Darkness: ‘like the paintings of a blind man’ is a reflection that engages both the painter and 43 of his works into a conversation alternating painting and aphoristic writing. Their order follows neither the chronology of the works nor a linear argument in the prose. And yet, the work generates the strongest feeling of there being a continuity in this peculiar dialogue of pictures and (...) poeticism, a continuity not clearly presented by logic, but one concerning what remains unpresented in presentation. The conversation is revelatory of their shared concerns with the energetic force of absence and is fascinating. (shrink)

This article offers an argument of genocide denial as an injustice perpetrated not only against direct victims and survivors of genocide, but also against future members of the victim group. In particular, I argue that in cases of persistent and systematic denial, i.e. denialism, it perpetrates an epistemic injustice against them: testimonial oppression. First, I offer an account of testimonial oppression and introduce Kristie Dotson’s notion of testimonial smothering as one form of testimonial oppression, a mechanism of coerced silencing particularly (...) pertinent to genocide denialism. Secondly, I turn to the epistemology of genocide denialism and, using the example of Turkey’s denialism of the Armenian genocide, show how it presents what Linda Martín Alcoff calls a substantive practice of ignorance. Thirdly, I apply these considerations to individual practices of genocide denial and analyse the particular characteristics of testimony on genocide, the speaker vulnerabilities involved and the conditions under which hearers will reliably fail to meet the dependencies of a speaker testifying to genocide. Finally, I explore the harms that testimonial oppression perpetrates on members of the victim group, insofar as it systematically deprives them of epistemic recognition. (shrink)

Genocide remembrance is a complex epistemological/ethical achievement, whereby survivors and descendants give meaning to the past in the quest for both personal-historical and social-historical truth. This paper offers an argument of epistemic injustice specifically as it occurs in relation to practices of (individual and collective) genocide remembrance. In particular, I argue that under conditions of genocide denialism, understood as collective genocide misremembrance and memory distortion, genocide survivors and descendants are confronted with hermeneutical oppression. Drawing on Sue Campbell’s relational, reconstructive account (...) of remembering, I argue that genocide denialism involves disrespectful challenges to memory, which systematically misrecognize rememberers. Adopting the case of Turkey’s denialism of the Armenian genocide, I discuss two interrelated mechanisms through which this can happen: i) through the systematic portrayal of survivors and descendants as vicious rememberers, and ii) through distortions of the very concept of ‘genocide’. Based on this, I show how hermeneutical and testimonial injustice are crucially interrelated when it comes to “contested” memories of historical injustice and the biographical testimony it gives rise to.

When we dream, we feel emotions in response to objects and events that exist only in the dream. One key question is whether these emotions can be said to be “essentially unfitting”, that is, always inappropriate to the evoking scenario. However, how we evaluate dream emotions for fittingness may depend on the model of dreams we adopt: the imagination or the hallucination model. If fittingness requires a match between emotion and evaluative properties of objects or events, it is prima facie (...) plausible that dream emotions could fail to fit under the imagination model because it is unfitting to have an emotion toward an object we do not believe to be real. Under the hallucination model, dream emotions could be unfitting because their objects do not exist but we believe them to be real. More nuance, however, is required. By comparing dream emotions with the emotions we experience while imagining, engaging with fiction, and hallucinating, we conclude that although there are compelling arguments in support of the claim that dream emotions are essentially unfitting, these arguments are not entirely convincing, and it is more plausible that particular dream emotions can be assessed for fittingness under either model of dreaming.

In light of our knowledge about neurodiversity, I argue that the cognitive science framework Miščević uses in Thought Experiments must be broaden to create a pluralistic account of thought experimentation, one able to account for the many ways thought experiments are replicated using not only visual models, but also arguments, conceptual analyses, and images as some of the many instruments used in the laboratory of our mind.

Integrative and naturalistic philosophy of mind can both learn from and contribute to the contemporary cognitive sciences of dreaming. Two related phenomena concerning self-representation in dreams demonstrate the need to bring disparate fields together. In most dreams, the protagonist or dream self who experiences and actively participates in dream events is or represents the dreamer: but in an intriguing minority of cases, self-representation in dreams is displaced, disrupted, or even absent. Working from dream reports in established databanks, we examine two (...) key forms of polymorphism of self-representation: dreams in which I take an external visuospatial perspective on myself, and those in which I take someone else's perspective on events. In remembering my past experiences or imagining future or possible experiences when awake, I sometimes see myself from an external or 'observer' perspective. By relating the issue of perspective in dreams to established research traditions in the study of memory and imagery, and noting the flexibility of perspective in dreams, we identify new lines of enquiry. In other dreams, the dreamer does not appear to figure at all, and the first person perspective on dream events is occupied by someone else, some other person or character. We call these puzzling cases 'vicarious dreams' and assess some potential ways to make sense of them. Questions about self-representation and perspectives in dreams are intriguing in their own right and pose empirical and conceptual problems about the nature of self-representation with implications beyond the case of dreaming.

As we become more aware of the potential causes and consequences of climate change we are left wondering: who is responsible? Climate change has the potential to harm large portions of the global population and, arguably, is already doing so. Further, climate change is argued to be human-caused. If this is true, then it seems to be the case that we can analyze climate change in terms of responsibility. I argue that we can approach environmental harms, such as climate change, (...) through a theory of collective responsibility. I propose an account of reductive collective responsibility that can apply to the unstructured collective causing climate change and determine what we are each individually morally responsible for. To avoid the critiques of reductive collective responsibility for large unstructured harms, I propose we separate the determination of membership and eligibility for responsibility from the attribution of responsibility. Through this method, I can speak to the individual responsibility of each member who contributes to climate change without holding them responsible for that which is outside their control. (shrink)

Val Plumwood's critical ecological feminism proposes a theorisation of the conceptual and logical foundations underlying the oppressions of women and nature within dominant western philosophical traditions, and a challenge to the dominant rationalist framework of mastery to which these oppressions are attributed. The present paper proposes, firstly, to expound the trajectory and development of CEF through Plumwood's body of work. Secondly, it will defend CEF from objections proposed by John Andrews, including that the critique of dualism fails to prove the (...) moral equality of human and non-human entities which it presupposes, and that its mutuality requirement implies the very hierarchy and exclusion it seeks to overcome. Finally, the paper will address the impact and significance of Plumwood's CEF in light of its foundational challenge to dominant frameworks of reason and logic, and to the methodologies and concerns of mainstream analytic philosophy itself. It will suggest that Plumwood's central thesis is essentially sound and that it is therefore of great significance to the task of reconceptualising human-nature relationships in a more rational, just and prudentially sound manner.

Online platforms like Instagram cover potentially distressing imagery with a sensitive-content screen (blurred imagery plus a content warning). Previous research suggests people typically choose to “uncover” and view screened content. In three studies, we investigated whether the presence of screens mitigates the negative emotional impact of viewing content. In Study 1, participants viewed positive and neutral images, and screens (with an option to view the negative images beneath) for a 5-minute period. In Study 2, half the participants saw a grey (...) mask in place of the typical sensitive-content screen. In addition, each image appeared for a fixed period (5 s) and participants had no option to uncover it. Study 3 was like Study 2 except half the participants saw negative images preceded by a sensitive-content screen and half saw negative images without screens. Overall, participants reported a significant increase in state anxiety and negative affect from pre-to post task when they were exposed to sensitive-content screens, whether or not they were also exposed to the negative imagery beneath. Our data suggest sensitive-content screens cause negative responses – state anxiety and negative affect – that do not translate to an emotional benefit when people view negative content. (shrink)

Two intertwined stories evince the influence of colonialism on Western universities. The first story centers on a conflict about wild rice research between the Anishinaabe people and the University of Minnesota. Underlying this conflict is a genetic notion of biological identity that facilitates the commodification of wild rice. This notion of identity is inextricably linked to agricultural control and expansion. The second story addresses the foundation of Western universities on the goals of civilization and capitalist productivity. These norms persist even (...) in diversity efforts through a focus on individualized notions of difference rather than socially contextualized and politically significant identities. The tendency to produce both knowledge and knowers as commodities results in the alienation, individuation, and abstraction of objects of research and researchers themselves. Decolonial change demands that we learn the specific histories of our universities and disciplines, break disciplinary boundaries, and contest commodification in knowledge production. (shrink)

This paper examines six cross-sector partnerships in South Africa and Zambia. These partnerships were part of a research study undertaken between 2003 and 2005 and were selected because of their potential to contribute to poverty reduction in their respective countries. This paper examines the context in which the partnerships were established, their governance and accountability mechanisms and the engagement and participation of the partners and the intended beneficiaries in the partnerships. We argue that a partnership approach which has proven successful (...) in one context can be used as a valuable learning resource. However, a partnership's work, which includes all aspects of the partnership and its activities, cannot necessarily be transferred directly to another partnership without a thorough and locally informed analysis of the context in which it is implemented. In addition, we suggest that it is difficult to assess whether the good intentions behind partnerships were translated into real benefits for target groups as effective monitoring and evaluation procedures were not in place in the partnerships studied. Similarly, the absence of regularised governance and accountability systems in partnerships made it difficult to support partner and beneficiary participation and engagement. We conclude that there is a need to move beyond a 'one-size-fits-all' approach to partnerships and that partnership replication should focus more strongly on the transfer of learning about partnership processes instead of simply copying partnership activities. Moreover, the development of stronger mechanisms for assessing and ensuring accountability towards both partners and intended beneficiaries is required if partnerships are to meet their intended objectives.

The intuitive view that memories are characterized by a feeling of pastness, perceptions by a feeling of presence, while imagination lacks either faces challenges from two sides. Some researchers complain that the “feeling of pastness” is either unclear, irrelevant or isn’t a real feature. Others point out that there are cases of memory without the feeling of pastness, perception without presence, and other cross-cutting cases. Here we argue that the feeling of pastness is indeed a real, useful feature, and although (...) this feeling does not define memory ontologically, it is a characteristic marker which helps us easily categorise a mental state first-personally. We outline several cognitive features that underlie this experience, including the feeling of past accessibility, ergonomic significance, immersion, objectivity and mental strength. Our account is distinctly phenomenal, rather than doxastic, although our web of beliefs may contribute to this experience. (shrink)

At the intersection of religion and sexuality, this article explores how lesbian, gay, bisexual, transgender, intersex and queer (LGBTIQ) people navigate dynamics of inclusion and exclusion within faith-based settings. Situated in a postcolonial setting, and with a specific focus on South Africa, the article delineates the oppressive dynamics at work at this intersection, along with how these are resisted through contemporary forms of activism. Grounded in a feminist analysis of relevant literature and of the field of activism in question, and (...) supplemented by interviews with key informants, the research offers a conceptual framework to advance transformative inclusion for LGBTIQ people within, and against, the dominant institutions, discourses and practices of faith.Contribution: This article contributes to the field of scholarship that concerns activism on sexual and gender rights in faith-based settings. It straddles theory and practice, offering an epistemological grounding for political action that advances the rights of LGBTIQ people. In bringing practitioner insights into academic discourse, the article adds to the burgeoning academic enquiry in this area, and offers a conceptual approach for supporting existing and new initiatives against marginalisation, exclusion and violence at the hands of faith.

Matrix models are widely used in biology to predict the temporal evolution of stage-structured populations. One issue related to matrix models that is often disregarded is the sampling variability. As the sample used to estimate the vital rates of the models are of finite size, a sampling error is attached to parameter estimation, which has in turn repercussions on all the predictions of the model. In this study, we address the question of building confidence bounds around the predictions of matrix (...) models due to sampling variability. We focus on a density-dependent Usher model, the maximum likelihood estimator of parameters, and the predicted stationary stage vector. The asymptotic distribution of the stationary stage vector is specified, assuming that the parameters of the model remain in a set of the parameter space where the model admits one unique equilibrium point. Tests for density-dependence are also incidentally provided. The model is applied to a tropical rain forest in French Guiana. (shrink)

A single mother is a person who is accountable for raising their children alone because they do not have a husband or live-in partner. Single mothers claim to have no co-parenting relationships at all, comparing single parents to those who are married, cohabiting, or without children, single parents experience the worst work-life balance. A single parent may feel overwhelmed by the demands of juggling child care, a career, paying bills, and maintaining household responsibilities. Single-parent households frequently deal with several extra (...) obligations and possible complications that other families would not. The study also emphasizes the difficulties and coping mechanisms faced by contractual single parents as well as their lived experiences. The study's findings, which were based on an Interpretative Phenomenological Analysis, were as follows: (1) Work-life balance can be difficult for single parents. They struggle to keep their jobs while taking care of their family because they are the only ones in charge of the children. (2) Single contractual mothers face particular difficulties due to a lack of resources for basic expenses. (3) Contractual single women lean on their kids, the good people in their lives, and their faith in God to get through problems. (shrink)

Hegel qualifiait la pièce Antigone de Sophocle de tragédie la plus parfaite. Peut-on, encore aujourd’hui, malgré les critiques ultérieures, soutenir cette idée et la fonder? Si la perfection de cette tragédie tient dans le tissage de conflits que Sophocle construit, nous devrons d’abord effiler chaque conflit, pour ensuite affilier chaque position à ce qui la fonde, et suivre enfin le déroulé tragique du fil d’Antigone.

Together with Max Weber, Georg Simmel is one of the founders of modern sociology. He is less well known as a philosopher. Here he emerges as a modern author who tries to uphold the claim of philosophy under the conditions of relativism, scientific positivism and historicism. His very own understanding of a this-worldly metaphysics as well as his affinity for mysticism play a prominent role in this"--Summary on t.p. verso.

In this paper, key concepts from the philosophy of critical realism and meta-Reality are used to develop an art education research project that can enhance the freedom of art students in their art work and, potentially, contribute to the promotion of emancipation beyond the world of art work. In the process of developing this project, the author engages in a two-way interrogation of both concepts and empirical research. The stratified model of reality, the ontological status of absence and the concepts (...) of transcendental identification, transcendental agency and the ground-state have informed decisions about data collection and contributed to the analysis of data in this study. The research results offer some empirical support for the philosophy of critical realism and meta-Reality, whilst also identifying potential inconsistencies. A further original feature of the paper is that it draws on the flow theory of Mihaly Csikszentmihalyi to complement Roy Bhaskar's account of the ground-state and of the nature of free-flowing activity; also using neuroscience to provide some neurological evidence for the differences between mindful and spontaneous activity. It is anticipated that the cross-analysis between cases resulting from the two-way interchange between theory and empirical evidence could help to generate a model for ‘unblocking the creative block’, experienced not only by students practising art-making, but also by the wider community.

Our eyes, bodies, and perspectives are constantly shifting as we observe the world. Despite this, we are very good at distinguishing between self-caused visual changes and changes in the environment: the world appears mostly stable despite our visual field moving around. This, it seems, also occurs when we are dreaming. As we visually investigate the dream environment, we track moving objects with our dream eyes, examine objects, and shift focus. These movements, research suggests, are reflected in the rapid movements or (...) saccades of our sleeping eyes. Do we really see the dream world in the same way that we see the real world? If we do, how could dreaming, usually assumed to be mind-generated hallucinations, replicate such an experience? This problem would be deflated if dreams are not hallucinations at all, but rather imagination, illusion or simply unrealistic. I argue that imagination and illusion views do not satisfactorily explain away the problem of vision and action in sleep. The imagination model is not a complete description of dreaming that is consistent with empirical research, and it is unlikely that the visual dream world is an illusion. Given that the dreaming visual experience is most likely active, hallucinatory, and at times a realistic world simulation, there are important implications for our understanding of visual perception and its relationship to movement. Evidence suggests that our dream eyes investigate the dream world as our waking eyes investigate the waking world. If changes to the unconsciously generated dream environment are perceived as external and unintentional while dream body movements are perceived as self-generated and intentional, current theory of visual perception may have to be expanded to account for how the dreaming mind generates a stable world in which we track and visually explore mind-generated objects.

Given the profound influence of social media and emerging evidence of its effects on human behavior and health, bioethicists have an important role to play in the development of professional standards of conduct for health professionals using social media and in the design of online systems themselves. In short, social media is a bioethics issue that has serious implications for medical practice, research, and public health. Here, we inventory several ethical issues across four areas at the intersection of social media (...) and health: the impact of social networking sites on the doctor‐patient relationship, the development of e‐health platforms to deliver care, the use of online data and algorithms to inform health research, and the broader public health consequences of widespread social media use. In doing so, we review discussions of these topics and emphasize the need for bioethics to focus more deeply on the ways online technology platforms are designed and implemented. We argue that bioethicists should turn their attention to the ways in which consumer engagement, bias, and profit maximization shape online content and, consequently, human behavior and health. We also offer a set of recommendations and suggest future directions for addressing ethical challenges in these domains. (shrink)

In this essay we argue that there is a contradiction lurking at the heart of Bernard Suits's seminal book on the philosophy of games, The Grasshopper, which has oddly gone unnoticed for 43 years. Suits argues that games need inefficiency and defines inefficiency such that it wouldn't exist in Utopia. This trivially entails that there could be no games in Utopia, yet the whole normative point of The Grasshopper is that games would be the only worthwhileactivity in Utopia. We then (...) diagnose Suits's error and suggest some ways forward. (shrink)

Many researchers have documented how AI and data driven technologies have the potential to have profound effects on our lives—in ways that make these technologies stand out from those that went before. Around the world, we are seeing a significant growth in interest and investment in AI in healthcare. This has been coupled with rising concerns about the ethical implications of these technologies and an array of ethical guidelines for the use of AI and data in healthcare has arisen. Nevertheless, (...) the question of if and how AI and data technologies can be ethical remains open to debate. This paper aims to contribute to this debate by considering the wide range of implications that have been attributed to these technologies and asking whether current ethical guidelines take these factors into account. In particular, the paper argues that while current ethics guidelines for AI in healthcare effectively account for the four key issues identified in the ethics literature (transparency; fairness; responsibility and privacy), they have largely neglected wider issues relating to the way in which these technologies shape institutional and social arrangements. This, I argue, has given current ethics guidelines a strong focus on evaluating the impact of these technologies on the individual, while not accounting for the powerful social shaping effects of these technologies. To address this, the paper proposes a Multiscale Ethics Framework, which aims to help technology developers and ethical evaluations to consider the wider implications of these technologies. (shrink)

Melanie Sarzano | : In this paper, I compare cases of self-deception and cases of pragmatic encroachment and argue that confronting these cases generates a dilemma about rationality. This dilemma turns on the idea that subjects are motivated to avoid costly false beliefs, and that both cases of self-deception and cases of pragmatic encroachment are caused by an interest to avoid forming costly false beliefs. Even though both types of cases can be explained by the same belief-formation mechanism, only (...) self-deceptive beliefs are irrational: the subjects depicted in high-stakes cases typically used in debates on pragmatic encroachment are, on the contrary, rational. If we find ourselves drawn to this dilemma, we are forced either to accept—against most views presented in the literature—that self-deception is rational or to accept that pragmatic encroachment is irrational. Assuming that both conclusions are undesirable, I argue that this dilemma can be solved. In order to solve this dilemma, I suggest and review several hypotheses aimed at explaining the difference in rationality between the two types of cases, the result of which being that the irrationality of self-deceptive beliefs does not entirely depend on their being formed via a motivationally biased process. | : Dans cet article, je compare les cas classiques de duperie de soi aux cas que l’on trouve dans les débats sur la question de l’empiètement pragmatique et défends l’idée selon laquelle ces deux types de cas peuvent être compris comme étant produits par un même mécanisme visant à éviter la formation de croyances fausses coûteuses. Cette comparaison nous mène naturellement à former un dilemme à propos de la rationalité des croyances. Le dilemme repose sur l’idée que bien que ce mécanisme mène à la formation de croyances irrationnelles dans les cas de duperie de soi, il ne semble pas affecter la rationa-lité du sujet dans les cas d’empiètement pragmatique : alors que les sujets autodupés sont irrationnels, les sujets décrits dans les cas d’empiètement pragmatique ne le sont pas. Pour résoudre ce dilemme sans rejeter les présupposés selon lesquels les croyances issues de la duperie de soi sont irrationnelles et que les cas sur lesquels repose l’empiètement pragmatique sont rationnels, je propose plusieurs hypothèses visant à expliquer cette différence, prouvant ainsi que ce dilemme n’est qu’apparent et que l’irrationalité de la duperie de soi ne peut uniquement dépendre de ce mécanisme sous l’influence de considérations pratiques.
