In the developing world, the dramatic male bias in tobacco use is usually ascribed to pronounced gender disparities in social, political, or economic power. This bias might also reflect under-reporting by woman and/or over-reporting by men. To test the role of gender inequality on gender differences in tobacco use we investigated tobacco use among the Aka, a Congo Basin foraging population noted for its exceptionally high degree of gender equality. We also tested a sexual selection hypothesis—that Aka men’s tobacco use (...) is related to risk taking. Tobacco use, income, tobacco purchases, tobacco sharing, reasons for using tobacco, risk taking, and other variables were measured using structured surveys and peer reports. Tobacco use was verified by testing for salivary cotinine, a nicotine metabolite. Contrary to expectations, we found a very large male bias in tobacco use. Low levels of use among females appeared to be explained by aversions to tobacco, concerns over its negative effects on fetal health, and a desire to attract husbands, who prefer nonsmoking wives. High male use appeared to be related to a desire to enhance hunting abilities and attract and/or retain wives, who prefer husbands that smoke. We conclude that low levels of smoking by Aka women are better explained by the hypothesis that women evolved to avoid plant toxins to protect their fetuses and nursing infants. High male use might be better explained by sexual selection. We also highlight the important role that recreational drugs appear to play in hunter-gatherer sharing relationships. (shrink)

We applaud Müller & Schumann (M&S) for bringing needed attention to the problem of motivation for common non-addictive drug use, as opposed to the usual focus on exotic drugs and addiction. Unfortunately, their target article has many underdeveloped and sometimes contradictory ideas. Here, we will focus on three key issues.

A long-standing theoretical tradition in clinical psychology and psychiatry sees deliberate self-harm , such as wrist-cutting, as “functional”—a means to avoid painful emotions, for example, or to elicit attention from others. There is substantial evidence that DSH serves these functions. Yet the specific links between self-harm and such functions remain obscure. Why don’t self-harmers use less destructive behaviors to blunt painful emotions or elicit attention? Economists and biologists have used game theory to show that, under certain circumstances, self-harmful behaviors by (...) economic agents and animals serve important strategic goals. In particular, “costly signals” can credibly reveal a “private state” in situations where verbal claims and other “cheap” signals might be disbelieved. Here, DSH is scrutinized using signaling theory, and a variant, the theory of bargaining with private information. The social contexts and associated features of DSH suggest that it might be a costly, and therefore credible, signal of need that compels social partners to respond. (shrink)

Museum workers have taken a massive hit during the pandemic when many museums closed their doors, cut staff hours, instituted layoffs and furloughs, and pushed more into precarity. For many workers, the effect of the pandemic has highlighted long-standing issues of racial, economic, gender and political inequality. This article engages with how workers are responding to this insecurity by highlighting worker-led feminist mobilizations for transformation in museums based in the United States and the United Kingdom. By focusing on efforts for (...) engaging with the Black Lives Matter movement, decolonizing the museum, unionizing workers and providing mutual aid, this article examines worker-led practices of transformation of the museum amid crisis. A special emphasis is put on how workers articulate the importance of feminist solidarity and collective action in envisioning a more just museum of the future. (shrink)

Commonsense reasoning about the physical world, as exemplified by "Iron sinks in water" or "If a ball is dropped it gains speed," will be indispensable in future programs. We argue that to make such predictions (namely, envisioning), programs should use abstract entities (such as the gravitational field), principles (such as the principle of superposition), and laws (such as the conservation of energy) of physics for representation and reasoning. These arguments are in accord with a recent study in physics instruction where (...) expert problem solving is related to the construction of physical representations that contain fictitious, imagined entities such as forces and momenta (Larkin 1983). We give several examples showing the power of physical representations. (shrink)

Human-Computer Interaction and games set a new domain in understanding people’s motivations in gaming, behavioral implications of game play, game adaptation to player preferences and needs for increased engaging experiences in the context of HCI serious games. When the latter relate with people’s health status, they can become a part of their daily life as assistive health status monitoring/enhancement systems. Co-designing HCI-SGs can be seen as a combination of art and science that involves a meticulous collaborative process. The design elements (...) in assistive HCI-SGs for Parkinson’s Disease patients, in particular, are explored in the present work. Within this context, the Game-Based Learning design framework is adopted here and its main game-design parameters are explored for the Exergames, Dietarygames, Emotional games, Handwriting games, and Voice games design, drawn from the PD-related i-PROGNOSIS Personalized Game Suite holistic approach. Two main data sources were involved in the study. In particular, the first one includes qualitative data from semi-structured interviews, involving 10 PD patients and four clinicians in the co-creation process of the game design, whereas the second one relates with data from an online questionnaire addressed by 104 participants spanning the whole related spectrum, i.e., PD patients, physicians, software/game developers. Linear regression analysis was employed to identify an adapted GBL framework with the most significant game-design parameters, which efficiently predict the transferability of the PGS beneficial effect to real-life, addressing functional PD symptoms. The findings of this work can assist HCI-SG designers for designing PD-related HCI-SGs, as the most significant game-design factors were identified, in terms of adding value to the role of HCI-SGs in increasing PD patients’ quality of life, optimizing the interaction with personalized HCI-SGs and, hence, fostering a collaborative human-computer symbiosis.

Future robots should have common sense about the world in order to handle the problems they will encounter. A large part of this commonsense knowledge must be naive physics knowledge, since carrying out even the simplest everyday chores requires familiarity with physics laws. But how should one start codifying this knowledge? What kind of skills should be elicited from the experts (each and every one of us)? This paper will attempt to provide some hints by studying the mental models of (...) force and motion. (shrink)

This article presents results from a multidisciplinary research project on the integration and transfer of language knowledge into robots as an empirical paradigm for the study of language development in both humans and humanoid robots. Within the framework of human linguistic and cognitive development, we focus on how three central types of learning interact and co-develop: individual learning about one's own embodiment and the environment, social learning (learning from others), and learning of linguistic capability. Our primary concern is how these (...) capabilities can scaffold each other's development in a continuous feedback cycle as their interactions yield increasingly sophisticated competencies in the agent's capacity to interact with others and manipulate its world. Experimental results are summarized in relation to milestones in human linguistic and cognitive development and show that the mutual scaffolding of social learning, individual learning, and linguistic capabilities creates the context, conditions, and requisites for learning in each domain. Challenges and insights identified as a result of this research program are discussed with regard to possible and actual contributions to cognitive science and language ontogeny. In conclusion, directions for future work are suggested that continue to develop this approach toward an integrated framework for understanding these mutually scaffolding processes as a basis for language development in humans and robots.

As the title Ritual and Religion in the Xunzi accurately suggests, this collection of essays edited by T. C. Kline III and Justin Tiwald addresses Xunzi’s perspective on ritual and religion. Some of the essays are new, others are have been published previously. As a whole, the book strives to portray Xunzi as a religious philosopher, and to elucidate his potential contribution to the understanding of religion and ritual. Although there are a variety of views presented, Xunzi is generally characterized (...) as renovating and reinterpreting religion, rather than denouncing it, as he has sometimes been interpreted.After an introduction, the first chapter is Edward J. Machle’s seminal 1976 essay “Xunzi as a Religious.. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Virtue, Nature, and Moral Agency in the XunziKurtis HagenVirtue, Nature, and Moral Agency in the Xunzi. Edited, with introduction, by T. C. Kline III and Philip J. Ivanhoe. Indianapolis: Hackett Publishing Company, 2000. Pp. xvii + 268.Virtue, Nature, and Moral Agency in the Xunzi, edited by T. C. Kline III and Philip J. Ivanhoe, is an anthology that has much to recommend it. It brings together several seminal (...) papers on Xunzi by established and distinguished scholars of Chinese philosophy, such as Antonio S. Cua, D. C. Lau, David S. Nivison, and Henry Rosemont, Jr. It also includes contributions from relative newcomers, who focused their dissertations on Xunzi's philosophy, namely T. C. Kline III and Eric Hutton. While most of these essays have been previously published, some appear in print for the first time in this volume. There is also a succinct introduction, name and subject indexes, and a targeted bibliography, which may serve as a reading list for those interested in supplementing their study of Xunzi. Another nicety is that references to passages in the Xunzi in older articles have been updated to include John Knoblock's translation1 as well as A Concordance to the Xunzi,2 and romanizations have been standardized to pinyin. [End Page 434]For the most part, the title Virtue, Nature, and Moral Agency in the Xunzi accurately represents the most prominent subject matter of the book. However, by "nature" what is meant is apparently "human nature," if that is an adequate translation for the concept Xunzi designates with the character xing. Xunzi's view of tian (the propensities of nature, the heavens) is not prominently discussed.3 Most of the essays, chapters 4 through 11 (the final chapter), deal extensively if not primarily with understanding Xunzi's conception of human nature. Chapters 5 through 7 are tied even closer together under the theme of moral agency (more on their connection below). Virtue is the topic of chapter 3 and plays a role in chapters 4 and 7.Although the first two chapters seem not to fall neatly within these categories, Henry Rosemont, Jr.'s contribution, "State and Society in the Xunzi: A Philosophical Commentary," seems an appropriate choice for the lead chapter of this collection. A sweeping polemic in defense of Xunzi's political philosophy, this seminal essay demonstrates the philosophical strength and potential relevance of Xunzi's thought. Specifically, Rosemont argues that Xunzi's political system is no less "reasonable" than democracy, and that while Xunzi advocates what Karl Popper would call a "closed society," Xunzi's system is defensible against Popper's critique of such societies.4The second chapter, "Ethical Uses of the Past in Early Confucianism: The Case of Xunzi," is authored by Antonio S. Cua, who has been a consistent contributor to the understanding of Xunzi's philosophy for more than twenty years. A collection of essays on Xunzi would be incomplete without Cua's work being represented. However, given the themes of the book, it is not entirely clear why this particular piece was selected. While Cua has written on both human nature and virtue in the Xunzi, this essay only tangentially addresses the theme of virtue. Nevertheless, it exemplifies the kind of careful scholarship characteristic of Cua's work, and there is something to be said for an anthology like this to exhibit breadth as well as focus. In his contribution, Cua analyzes Xunzi's appeal to history in terms of its "pedagogical function," "rhetorical function," "elucidative function," and "evaluative function."In chapter 3, "Virtues in Xunzi's Thought," Jonathan W. Schofer offers a lucid depiction of Xunzi's moral theory as a kind of virtue theory, despite the lack of any systematic analysis on Xunzi's part of a specific set of virtues. He then suggests that, given Xunzi's theory and goals, the omission of any analysis of specific virtues may have been deliberate.The last eight chapters deal extensively with the issue of human nature. Chapter 4, "Xunzi: Morality as Psychological Constraint," by Joel J. Kupperman, compares Xunzi's and Mencius' conceptions of human nature. Kupperman argues that, unlike Mencius, Xunzi does not really have a "view of human... (shrink)

The concept of noman in Hagen encompasses a local theory of consciousness, agency, and morality. Interview materials are given to illustrate notions of how the noman works. The Hageners recognize a kind of duality between mind and body but no fundamental split between them. Their theory of consciousness is also a theory of morality and ethics, as well as a recognition of creative agency in life. Key words: Mount Hagen, person, gender, body/mind.

How do thought and language manage to be 'about' aspects of the world? J. Robert G. Williams investigates how representation arises out of a fundamentally non-representational world, showing the explanatory relations between the representational properties of language, of thought, and of perception and intention.

A new way to transpose the virtue epistemologist’s ‘knowledge = apt belief’ template to the collective level, as a thesis about group knowledge, is developed. In particular, it is shown how specifically judgmental belief can be realised at the collective level in a way that is structurally analogous, on a telic theory of epistemic normativity (e.g., Sosa 2020), to how it is realised at the individual level—viz., through a (collective) intentional attempt to get it right aptly (whether p) by alethically (...) affirming that p. An advantage of the proposal developed is that it is shown to be compatible with competing views—viz., joint acceptance accounts and social-distributive accounts—of how group members must interact in order to materially realise a group belief. I conclude by showing how the proposed judgment-focused collective (telic) virtue epistemology has important advantages over a rival version of collective virtue epistemology defended in recent work by Jesper Kallestrup (2016).

Strange inversions occur when things work in ways that turn received wisdom upside down. Hume offered a strangely inverted story about causation, and Darwin, about apparent design. Dennett suggests that a strange inversion also occurs when we project our own reactive complexes outward, painting our world with elusive properties like cuteness, sweetness, blueness, sexiness, funniness, and more. Such properties strike us as experiential causes, but they are really effects—a kind of shorthand for whole sets of reactive dispositions rooted in the (...) nuts and bolts of human information processing. Understanding the nature and origins of that strange inversion, Dennett believes, is thus key to understanding the nature and origins of human experience itself. This paper examines this claim, paying special attention to recent formulations that link that strange inversion to the emerging vision of the brain as a Bayesian estimator, constantly seeking to predict the unfolding sensory barrage.

It is argued that trust is a performative kind and that the evaluative normativity of trust is a special case of the evaluative normativity of performances generally. The view is shown to have advantages over competitor views, e.g., according to which good trusting is principally a matter of good believing (e.g., Hieronymi, 2008; McMyler, 2011), or good affect (e.g., Baier, 1986; Jones, 1996), or good conation (e.g., Holton, 1994). Moreover, the view can be easily extended to explain good (and bad) (...) distrust, where the latter is understood as aimed (narrow-scoped) forbearance from trusting. The overarching framework—which assimilates the evaluative norms of trusting (and distrusting) to performance-theoretic norms—supplies us with an entirely new lens to view traditional philosophical problems about what is involved in trusting and distrusting well and badly, and thus, places our capacity to make progress on problems in this area on a new footing.

The meta-problem is 'the problem of explaining why we think that there is a problem of consciousness' (Chalmers, 2018, p. 6). This presupposes that we think there is a problem in the first place. We challenge the breadth of this 'we', arguing that there is already sufficient empirical evidence to cast doubt on the claim. We then add to this body of evidence, presenting the results of a new cross-cultural study extending the work of Sytsma and Machery (2010).

The conservation of energy and momentum have been viewed as undermining Cartesian mental causation since the 1690s. Modern discussions of the topic tend to use mid-nineteenth century physics, neglecting both locality and Noether’s theorem and its converse. The relevance of General Relativity has rarely been considered. But a few authors have proposed that the non-localizability of gravitational energy and consequent lack of physically meaningful local conservation laws answers the conservation objection to mental causation: conservation already fails in GR, so there (...) is nothing for minds to violate. This paper is motivated by two ideas. First, one might take seriously the fact that GR formally has an infinity of rigid symmetries of the action and hence, by Noether’s first theorem, an infinity of conserved energies-momenta. Second, Sean Carroll has asked how one should modify the Dirac–Maxwell–Einstein equations to describe mental causation. This paper uses the generalized Bianchi identities to show that General Relativity tends to exclude, not facilitate, such Cartesian mental causation. In the simplest case, Cartesian mental influence must be spatio-temporally constant, and hence 0. The difficulty may diminish for more complicated models. Its persuasiveness is also affected by larger world-view considerations. The new general relativistic objection provides some support for realism about gravitational energy-momentum in GR. Such realism also might help to answer an objection to theories of causation involving conserved quantities, because energies-momenta would be conserved even in GR. (shrink)

Malthus did not leave us with a systematic treatment of colonization, but from remarks scattered throughout his publications and correspondence it is possible to assemble a fairly coherent account of his views on the advantages and disadvantages of colonies, and on the reasons why some have failed and others succeeded. Included in these scattered remarks are some comparisons between his own views on colonies and those of Adam Smith. The question of the relationship between Malthus and Adam Smith is a (...) rather complex and subtle one, and cannot be given the full consideration it deserves in one short paper. But, as a general summary, it can be said that Malthus had a high regard for Smith and considered himself a follower and disciple of Smith, by contrast with Ricardo, James Mill, and McCulloch etc., whom he considered as exponents of a ‘New System of Political Economy”. His own Principles of Political Economy was conceived as a collection of ‘tracts or essays”, not as a new systematic treatise replacing the Wealth of Nations, Joseph Gamier in his article ‘Malthus” in the Dictionnaire de l'Economie Politique, 1852, saw that the title of the Principles was in fact a misnomer: ‘Malgré son titre, le livre sur les Principes n'est point un traité complet, mais seulement une collection de dissertations.” In what was probably intended as a criticism of Ricardo's Principles of Political Economy and Taxation, 1817, Malthus stated that the ‘present period … seems to be unpropitious to the publication of a new systematic treatise on political economy”, and, referring to Smith's work, stated that ‘the treatise which we already possess is still of the very highest value”. Nevertheless, despite professing his affiliation, Malthus did not hesitate to criticize Smith when he disagreed with him. He recognized that the Wealth of Nations contained ‘controverted points” and that it would require some ‘additions … which the more advanced stage of the science has rendered necessary”. (shrink)

A change in sense of self is an outcome commonly associated with Buddhist meditation. However, the sense of self is construed in multiple ways, and which changes in self-related processing are expected, intended, or possible through meditation is not well understood. In a qualitative study of meditation-related challenges, six discrete changes in sense of self were reported by Buddhist meditators: change in narrative self, loss of sense of ownership, loss of sense of agency, change in sense of embodiment, change in (...) self-other or self-world boundaries, and loss of sense of basic self. Changes in sense of self could be transient or enduring, positive or distressing, enhancing or impairing. These changes were also given varied appraisals, ranging from insights associated with Buddhist doctrines to psychopathologies such as depersonalization. In this study of practitioners reporting meditation-related challenges, more global changes in sense of self were associated with higher levels of impairment. These results have implications for both Buddhist meditation as well as mindfulness-based interventions. (shrink)

A plethora of normative conservation concepts have recently emerged, most of which are ill-defined: biological diversity, biological integrity, ecological restoration, ecological services, ecological rehabilitation, ecological sustainability, sustainable development, ecosystem health, ecosystem management, adaptive management, and keystone species are salient among them. These normative concepts can be organized and interpreted by reference to two new schools of conservation philosophy, compositionalism and functionalism. The former comprehends nature primarily by means of evolutionary ecology and considers Homo sapiens separate from nature. The latter comprehends (...) nature primarily by means of ecosystem ecology and considers Homo sapiens a part of nature. Biological diversity, biological integrity, and ecological restoration belong primarily in the compositionalist glossary; the rest belong primarily in the functionalist glossary. The former set are more appropriate norms for reserves, the latter for areas that are humanly inhabited and exploited. In contrast to the older schools of conservation philosophy, preservationism and resourcism, compositionalism and functionalism are complementary, not competitive and mutually exclusive. As the historically divergent ecological sciences—evolutionary ecology and ecosystem ecology—are increasingly synthesized, a more unified philosophy of conservation can be envisioned. (shrink)

In the paper, the originator of the hiddenness argument, J. L. Schellenberg, responds to papers that challenge his reasoning. In his remarks he puts an emphasis on the concept of divine love and he explains why it is not only connected to the idea of the Christian God. He also clarifies his position on ultimism.

The Limits of Thought is a series of penetrating dialogues between the great spiritual leader, J. Krishnamurti and the renowned physicist, David Bohm. The starting point of their engaging exchange is the question: If truth is something different than reality, then what place has action in daily life in relation to truth and reality? We see Bohm and Krishnamurti explore the nature of consciousness and the condition of humanity. These enlightening dialogues address issues of truth, desire awareness, tradition, and love. (...) Limits of Thought is an important book by two very respected and important thinkers. Anyone interested to see how Krishnamurti and Bohm probe some of the most essential questions of our very existence will be drawn to this great work. (shrink)
