BackgroundSleep, physical activity, and diet have been associated with mental health and well-being individually in young adults. However, which of these “big three” health behaviors most strongly predicts mental health and well-being, and their higher-order relationships in predictive models, is less known. This study investigated the differential and higher-order associations between sleep, physical activity, and dietary factors as predictors of mental health and well-being in young adults.MethodIn a cross-sectional survey design, 1,111 young adults ages 18–25 from New Zealand and the (...) United States answered an online survey measuring typical sleep quantity and quality; physical activity; and consumption of raw and processed fruit and vegetables, fast food, sweets, and soda, along with extensive covariates and the outcome measures of depressive symptoms [measured by the Center for Epidemiological Depression Scale ] and well-being.ResultsControlling for covariates, sleep quality was the strongest predictor of depressive symptoms and well-being, followed by sleep quantity and physical activity. Only one dietary factor—raw fruit and vegetable consumption—predicted greater well-being but not depressive symptoms when controlling for covariates. There were some higher-order interactions among health behaviors in predicting the outcomes, but these did not survive cross-validation.ConclusionSleep quality is an important predictor of mental health and well-being in young adults, whereas physical activity and diet are secondary but still significant factors. Although strictly correlational, these patterns suggest that future interventions could prioritize sleep quality to maximize mental health and well-being in young adults. (shrink)

In addition to being uncertain about what the world is like, one can also be uncertain about one’s own spatial or temporal location in the world. My aim is to pose a problem arising from the interaction between these two sorts of uncertainty, solve the problem, and draw two lessons from the solution.

In this paper I defend anti-realism about race and a new theory of racialization. I argue that there are no races, only racialized groups. Many social constructionists about race have adopted racial formation theory to explain how ‘races’ are formed. However, anti-realists about race cannot adopt racial formation theory, because it assumes the reality of race. I introduce interactive constructionism about racialized groups as a theory of racialization for anti-realists about race. Interactive constructionism moves the discussion away from the dichotomous (...) (social vs. biological) metaphysics that has marred this debate, and posits that racialized groups are the joint products of a broad range of non-racial factors, which interact. (shrink)

There is a huge chasm between the notion of lawful determination that figures in fundamental physics, and the notion of causal determination that figures in the "folk physics" of everyday objects. In everyday life, we think of the behavior of an ordinary object as being determined by a small set of simple conditions. But in fundamental physics, no such conditions suffice to determine an ordinary object's behavior. What bridges the chasm is that fundamental physical laws make the folk picture of (...) the world approximately true in certain domains. How? In part, by entailing that many objects are approximately isolated from most of their environments. Dynamical laws yield this result only in conjunction with appropriate statistical assumptions about initial conditions. (shrink)

In "Counterfactual Dependence and Time's Arrow", David Lewis defends an analysis of counterfactuals intended to yield the asymmetry of counterfactual dependence: that later affairs depend counterfactually on earlier ones, and not the other way around. I argue that careful attention to the dynamical properties of thermodynamically irreversible processes shows that in many ordinary cases, Lewis's analysis fails to yield this asymmetry. Furthermore, the analysis fails in an instructive way: it teaches us something about the connection between the asymmetry of overdetermination (...) and the asymmetry of entropy. (shrink)

Experimental research suggests that people draw a moral distinction between bad outcomes brought about as a means versus a side effect (or byproduct). Such findings have informed multiple psychological and philosophical debates about moral cognition, including its computational structure, its sensitivity to the famous Doctrine of Double Effect, its reliability, and its status as a universal and innate mental module akin to universal grammar. But some studies have failed to replicate the means/byproduct effect especially in the absence of other factors, (...) such as personal contact. So we aimed to determine how robust the means/byproduct effect is by conducting a meta-analysis of both published and unpublished studies (k = 101; 24,058 participants). We found that while there is an overall small difference between moral judgments of means and byproducts (standardized mean difference = 0.87, 95% CI 0.67 – 1.06; standardized mean change = 0.57, 95% CI 0.44 – 0.69; log odds ratio = 1.59, 95% CI 1.15 – 2.02), the mean effect size is primarily moderated by whether the outcome is brought about by personal contact, which typically involves the use of personal force.

This article investigates the potential role of the commons in the future transformation of digital capitalism by comparing it to the role of the commons in the transition to capitalism. In medieval and early modern Europe the commons supported gradual social and technological innovation as well as a new civil society organized around the combination of commons-based petty production and new ideals of freedom and equality. Today the new commons generated by the global real subsumption of ordinary life processes are (...) supporting similar forms of commons-based petty production. After positioning the new petty producers within the framework of the crisis of digital capitalism, the article concludes by extrapolating a number of hypothetical scenarios for their role in its future transformation.

What is life and what does it mean to be in the living political universe of entitiness without rhyme or reason? Flappy exudate, a bag in a bag, corpuscles of corporeality, worms (or flesh tubes) with appendages, even the cult of first involution – these are our body pods and the hunger and thirst of being-in. How can the situation of anatomical form be analysed without the illusion of instrumentalized reflection? Perhaps by amalgamating the categories and their issues. The issuance (...) of taxonomy is the actual fine muck of excrement, which every brick of ordered life leaks as exudence and decay. Deep thoughts leave a mucal snail trail of what was tabular-seeming about our bodily situation, our environs, our friends, our experiments and our nourishment. Especially in this current age of 露 露 and 娜娜 (Lulu and Nana), our first officially public transgenic kindred, the question becomes, ‘who are these free-living divergences and what does it mean to be the uber-ding beyond geoengineering’s capabilities?’.

Intellectual autonomy has long been identified as an epistemic virtue, one that has been championed influentially by Kant, Hume and Emerson. Manifesting intellectual autonomy, at least, in a virtuous way, does not require that we form our beliefs in cognitive isolation. Rather, as Roberts and Wood note, intellectually virtuous autonomy involves reliance and outsourcing to an appropriate extent, while at the same time maintaining intellectual self-direction. In this essay, I want to investigate the ramifications for intellectual autonomy of a particular (...) kind of epistemic dependence: cognitive enhancement. Cognitive enhancements involve the use of technology and medicine to improve cognitive capacities in healthy individuals, through mechanisms ranging from smart drugs to brain-computer interfaces. With reference to case studies in bioethics, as well as the philosophy of mind and cognitive science, it is shown that epistemic dependence, in this extreme form, poses a prima facie threat to the retention of intellectual autonomy, specifically, by threatening to undermine our intellectual self-direction. My aim will be to show why certain kinds of cognitive enhancements are subject to this objection from self-direction, while others are not. Once this is established, we’ll see that even some extreme kinds of cognitive enhancement might be not merely compatible with, but constitutive of, virtuous intellectual autonomy. (shrink)

This article develops an analogy proposed by Stachel between general relativity (GR) and quantum mechanics (QM) as regards permutation invariance. Our main idea is to overcome Pooley's criticism of the analogy by appeal to paraparticles. In GR, the equations are (the solution space is) invariant under diffeomorphisms permuting spacetime points. Similarly, in QM the equations are invariant under particle permutations. Stachel argued that this feature—a theory's ‘not caring which point, or particle, is which’—supported a structuralist ontology. Pooley criticizes this analogy: (...) in QM the (anti-)symmetrization of fermions and bosons implies that each individual state (solution) is fixed by each permutation, while in GR a diffeomorphism yields in general a distinct, albeit isomorphic, solution. We define various versions of structuralism, and go on to formulate Stachel's and Pooley's positions, admittedly in our own terms. We then reply to Pooley. Though he is right about fermions and bosons, QM equally allows more general types of particle symmetry, in which states (vectors, rays, or density operators) are not fixed by all permutations (called ‘paraparticle states’). Thus Stachel's analogy is revived. (shrink)

In this article, I suggest that an open mind wholly unburdened by preconceptions and prejudgments is a mistaken ideal. Not only is it unrealistic; it deprives us of context and background knowledge relevant to judging well. I begin with two cases that show how the ideal of the “prejudice-free” mind, though appealing, may end up thwarting good judgment: blind assessment and “blank-slate” jury selection. I then trace the prejudice-free ideal to the Enlightenment, exposing its roots in the subject-object worldview. Drawing (...) on Heidegger, I suggest that the subject-object worldview is misguided and that all judgment involves a prior understanding of the matter we judge. To have an open mind, paradoxically, is to have a stake in defending a prior understanding, to be possessed of an understanding of the good that one wishes to promote. I then draw out the implications of this view for how we might make sense of cultural differences,... (shrink)

Argumentation Frameworks provide a fruitful basis for exploring issues of defeasible reasoning. Their power largely derives from the abstract nature of the arguments within the framework, where arguments are atomic nodes in an undifferentiated relation of attack. This abstraction conceals different senses of argument, namely a single-step reason to a claim, a series of reasoning steps to a single claim, and reasoning steps for and against a claim. Concrete instantiations encounter difficulties and complexities as a result of conflating these senses. (...) To distinguish them, we provide an approach to instantiating AFs in which the nodes are restricted to literals and rules, encoding the underlying theory directly. Arguments in these senses emerge from this framework as distinctive structures of nodes and paths. As a consequence of the approach, we reduce the effort of computing argumentation extensions, which is in contrast to other approaches. Our framework retains the theoretical and computational bene..

I consider Glimcher's claim to have given an account of mental functioning that is at once neurological and decision-theoretical. I am skeptical, but remark on some good ideas of Glimcher's.

On grounds of autonomy, is comprehensive education — an approach to education that attempts to facilitate the acceptance of certain beliefs and ways of life as being correct, and refuses to sympathetically expose students to contrary beliefs and ways of life — ethically suspect? Recently, Bryan R. Warnick has argued that it is. In this essay, Adam D. Bailey critically evaluates Warnick's argument, and contends that it is unsuccessful. In particular, he argues that Warnick's argument from necessity does not (...) succeed. Bailey then addresses a potential response to his critique of Warnick's argument — that of developing an argument from facilitation rather than necessity — and argues that, contrary to the argument from necessity, the argument from facilitation does provide support for the claim that comprehensive education is ethically suspect. However, Bailey attempts to show that even granting the facilitation argument, it is plausible to hold that, on grounds of autonomy, comprehensive education need not be seen as ethically suspect.

Most of what we know about teaching comes from research among people living in large, politically and economically stratified societies with formal education systems and highly specialized roles with a global market economy. In this paper, we review and synthesize research on teaching among contemporary hunter-gatherer societies. The hunter-gatherer lifeway is the oldest humanity has known and is more representative of the circumstances under which teaching evolved and was utilized most often throughout human history. Research among contemporary hunter-gatherers also illustrates (...) a complex pattern of teaching that is both consistent with and distinct from teaching in other small- and large-scale societies with different subsistence practices and cultural forms. In particular, we find that the cultural emphasis on individual autonomy and socio-political egalitarianism among hunter-gatherers differently shapes how teaching occurs. For example, teaching clearly exists among hunter-gatherers and appears in many forms, including institutionalized instruction in valued cultural and technical skills. However, teaching tends to be less common in hunter-gatherer societies because people live in small, intimate egalitarian, groups that support each other’s learning in a variety of ways without teaching. Furthermore, foundational cultural schemas of autonomy and egalitarianism impact the nature of teaching. For example, adults and older children limit their interventions, permitting autonomous learning, and, when they occur, teaching episodes are generally brief, subtle, indirect, and situated in a present activity. We discuss the implications of this research in terms of discussions of the evolution of human cognition and the co-evolution of teaching and culture through the process of cultural niche construction.

I develop a new argument against Russellian Monism about consciousness.

The World Bank is committed to “work[ing] with countries to improve the health, nutrition and population outcomes of the world's poor, and to protect[ing] the population from the impoverishing effects of illness, malnutrition and high fertility”.1 Ethical issues arise in the interpretation of these objectives and in helping countries formulate strategies and policies. It is these ethical issues—which are often not acknowledged by commentators—that are the subject of this paper. It asks why there should be a focus on the poor, (...) and explores the link between improving the health of the poor, and reducing health inequalities between the poor and better-off. It discusses difficult ethical issues at both the global level and the country level. (shrink)

Noise in behavior is often viewed as a nuisance: while the mind aims to take the best possible action, it is let down by unreliability in the sensory and response systems. How researchers study cognition reflects this viewpoint – averaging over trials and participants to discover the deterministic relationships between experimental manipulations and their behavioral consequences, with noise represented as additive, often Gaussian, and independent. Yet a careful look at behavioral noise reveals rich structure that defies easy explanation. First, both (...) perceptual and preferential judgments show that sensory and response noise may potentially only play minor roles, with most noise arising in the cognitive computations. Second, the functional form of the noise is both non-Gaussian and non-independent, with the distribution of noise being better characterized as heavy-tailed and as having substantial long-range autocorrelations. It is possible that this structure results from brains that are, for some reason, bedeviled by a fundamental design flaw, albeit one with intriguingly distinctive characteristics. Alternatively, noise might not be a bug but a feature: indeed, we suggest that noise is fundamental to how cognition works. Specifically, we propose that the brain approximates probabilistic inference with a local sampling algorithm, one that uses randomness to drive its exploration of alternative hypotheses. Reframing cognition in this way explains the rich structure of noise and leads to a surprising conclusion: that noise is not a symptom of cognitive malfunction but plays a central role in underpinning human intelligence.

Philosophers view themselves as critical thinkers par excellence. But they have overlooked the institutional arrangements that govern their lives. The early twentieth-century research university disciplined philosophers, placing them in departments, where they wrote for and were judged by their disciplinary peers. Oddly, this change has been unremarked upon, or has been treated as simply part of the necessary professionalization of an academic field of research. The department has been tacitly assumed to be a neutral space from which thought germinates; it (...) is not itself an object of reflection. We find no explorations of the effects that departmentalization might have on philosophical theorizing, or speculations about where else philosophers could be housed, or how, by being located elsewhere, they might develop alternative accounts of the world or have come up with new ways of philosophizing.

From folk tales to movies, stories possess features which naturally suit them to contribute to the growth of virtue. In this article I show that the fictional exemplars help the learner to grasp the moral importance of internal states and resolves a tension between existing kinds of exemplars discussed by virtue ethicists. Stories also increase the information conveyed by virtue terms and aid the growth of prudence. Stories can provide virtuous exemplars, inform learners as to the nature of the virtues (...) and offer practice in developing situational judgement. As such they are a significant resource for virtue ethics and moral education. (shrink)

This article considers the relevance of time theory for Beck's theory of reflexive modernization and vice versa. It focuses in particular on discontinuity in the context of continuity, on decontextualization, naturalization and responsibility as key concerns of both perspectives on the industrial way of life. It makes explicit the temporal underpinnings of that cultural form with respect to five Cs: the creation of time to human design (C1), the commodification of time (C2), the compression of time (C3), the control of (...) time (C4) and the colonization of time (C5). It concludes that explicit concern with temporal relations shows reflexive modernization in action and facilitates improved knowledge for deliberative change. (shrink)

In forms of physical recreation associated with ‘wilderness experiences’, such as backcountry hiking or mountain climbing, technology is omnipresent. As a result, some may wonder whether genuine wilderness experiences are possible. In this essay, I argue that wilderness experiences are possible and that they can be enhanced through games. That is, I contend there are often physically challenging aspects to wilderness experiences that certain games can help to promote. This analysis will stress the fact that Bernard Suits delineated two comparable (...) but distinct ways to engage in games. Following Suits’s logic, I explain how ‘literal skills’ like walking or climbing can function as the ‘constitutive skills’ of games. I then consider how games predicated on ‘literal skills’ can help promote the meanings available in wilderness experiences. (shrink)

This paper offers an analysis of work on human development in evolutionary anthropology from a Thomist perspective. I show that both fields view care for others as fundamental to human nature and interpret cooperative breeding as expression of the virtue of charity. I begin with an analysis of different approaches to the relationship between evolutionary anthropology and moral theory. I argue that ethical naturalism is the approach best suited to interdisciplinary dialogue, since it holds that natural facts are useful for (...) moral theory but do not encompass it. This forms the basis for a Thomist analysis of some key features of human evolution including bipedalism, higher encephalisation and extended childhood. In each case I explain how these parts of our nature contributed to the evolution of modern humans, and how each is reliant upon communal care. Finally, I offer three observations on these facts from a Thomist perspective. Firstly, that a good human life necessarily involves caring for others and being cared for ourselves. Secondly, that this is exemplified in the virtue of charity, which is the ground of all virtue. Finally, that the need for such care shows that human flourishing cannot be attained without divine aid. (shrink)

Working from Adorno’s notion of negative dialectics, this essay charts a dialectical course of resistance toward a horizon of universal freedom. Rather than propose relations between ideal types of resistance, it emphasizes the ineliminable historical dimensions of not only real-world resistance movements but also the philosophical and political theorizing that attempts to make sense of them. In doing so it brings out certain conceptual relations that emerge or recede as the context of resistance shifts. The first moment considers the dichotomy (...) between reform and revolution, the second moment delves into modes of reform, and the third looks to modes of revolution. Along the way the essay discusses the work of such varied figures and organizations as Rosa Luxemburg, John Rawls, Martin Luther King, Jr., Candice Delmas, Robin Celikates, Kimberlee Brownlee, Emma Goldman, Students for a Democratic Society and the Weather Underground, and the Black Panther Party and the Black Liberation Army. In the end, the essay is written in the service of understanding the stakes and presuppositions of resistance, in theory and practice. (shrink)

We develop a Gentzen-style proof theory for super-Belnap logics, expanding on an approach initiated by Pynko. We show that just like substructural logics may be understood proof-theoretically as logics which relax the structural rules of classical logic but keep its logical rules as well as the rules of Identity and Cut, super-Belnap logics may be seen as logics which relax Identity and Cut but keep the logical rules as well as the structural rules of classical logic. A generalization of the (...) cut elimination theorem for classical propositional logic is then proved and used to establish interpolation for various super-Belnap logics. In particular, we obtain an alternative syntactic proof of a refinement of the Craig interpolation theorem for classical propositional logic discovered recently by Milne. (shrink)

In this paper I aim to defend one version at least of Hume’s dictum: roughly, the idea that possibility is determined by ontology through something like independent variation. My defence is broadly pragmatic, in the sense that adherence to something like Hume’s dictum delivers at least three benefits. The first benefit is that, through Hume’s dictum, a physical theory’s ontology delimits a range of possibilities, that I call kinematical possibilities, which serves as a sufficiently permissive notion of possibility to sustain (...) something like an intensional semantics for its claims, and a sufficiently demanding notion of supervenience to sustain plausible claims of inter-theoretic reduction and theoretical equivalence. The second benefit is that Hume’s dictum allows us to work backwards from a range of kinematical possibilities to an ontology. This is especially useful when aiming to glean an interpretation of a physical theory, since often we are more confident that we have arrived at the right space of possibilities than that we have arrived at the right ontology. The third benefit is that Hume’s dictum —- at least the version I aim to defend here —- may be applied to physical theories more or less as we find them, and therefore we can practice something resembling ontology without having to force our theories into some Procrustean bed, such as a first-order language.

A familiar point in the literature on the epistemology of disagreement is that in the face of disagreement with a recognised epistemic peer the epistemically virtuous agent should adopt a stance of intellectual humility. That is, the virtuous agent should take a conciliatory stance and reduce her commitment to the proposition under dispute. In this paper, we ask the question of how such intellectual humility would manifest itself in a corresponding peer disagreement regarding knowledge-how. We argue that while it is (...) relatively straightforward to recast this debate in terms of a reductive intellectualist account of knowledge-how, whereby knowledge-how just is a matter of having a particular propositional attitude, the issue becomes more complex once we turn to anti-intellectualist positions. On these views, after all, such a disagreement won’t be just a matter of disagreeing about the truth of a proposition. Accordingly, to the extent that some kind of conciliation is plausibly required of the virtuous agent in the face of a recognised peer disagreement, this conciliation will not consist simply in belief revision. We propose a novel way to address this problem. We claim that what is required of the epistemically virtuous agent when confronted with peer disagreement regarding knowing how to φ is that thereafter she should be disposed to employ her way of φ-ing across a narrower range of practical circumstances than beforehand. Moreover, just as an agent needs to call on her intellectual virtues in order to determine the extent of conciliation required in an ordinary case of epistemic peer disagreement, so the intellectual virtues will play an important role in determining this shift in dispositions to φ that occurs as regards epistemic peer disagreement about knowledge-how.

Recent interest in non-well-founded set theories has been concentrated on Aczel's anti-foundation axiom AFA. I compare this axiom with some others considered by Aczel, and argue that another axiom, FAFA, is superior in that it gives the richest possible universe of sets consistent with respecting the spirit of extensionality. I illustrate how using FAFA instead of AFA might result in an improvement to Barwise and Etchemendy's treatment of the liar paradox.
