Microbes in the gastrointestinal tract are under selective pressure to manipulate host eating behavior to increase their fitness, sometimes at the expense of host fitness. Microbes may do this through two potential strategies: (i) generating cravings for foods that they specialize on or foods that suppress their competitors, or (ii) inducing dysphoria until we eat foods that enhance their fitness. We review several potential mechanisms for microbial control over eating behavior including microbial influence on reward and satiety pathways, production of (...) toxins that alter mood, changes to receptors including taste receptors, and hijacking of the vagus nerve, the neural axis between the gut and the brain. We also review the evidence for alternative explanations for cravings and unhealthy eating behavior. Because microbiota are easily manipulatable by prebiotics, probiotics, antibiotics, fecal transplants, and dietary changes, altering our microbiota offers a tractable approach to otherwise intractable problems of obesity and unhealthy eating.

Wayfinding is generally understood as the process of purposefully navigating to distant and non-visible destinations. Within this broad framework, uninformed searching entails finding one’s way to a target destination, in an unfamiliar environment, with no knowledge of its location. Although a variety of search strategies have been previously reported, this research was largely conducted in the laboratory or virtual environments using simplistic and often non-realistic situations, raising questions about its ecological validity. In this study, we explored how extant findings on (...) searching translate to a real-world environment, using a phenomenologically informed experiment. Our findings demonstrate a previously undescribed complex and dynamic interplay of different search strategies. Importantly, our results reveal that: (i) the presence of other people is importantly entangled with the process of searching; and (ii) people frequently probe and switch between search strategies based on local environmental characteristics. Together, our results reveal that search behaviour is critically dependent on environmental features and that searching in complex real-world settings should not be conceptualised as depending on a simple singular strategy. This raises questions about the dominance of laboratory-based experiments and their narrow cognitivist framework, highlighting the value of studying wayfinding in the real world. (shrink)

Our ability to survive in a world beset by looming global perils depends ultimately on our collective will to harness our intellects and change our behaviors. In order to respond appropriately, people must first believe that serious problems exist, that there are potential solutions, and that they have a role to play in finding and implementing them. Without such beliefs, individual change is unlikely. In order to promote belief change, it is important to understand how beliefs are learned, what their (...) functions are, and why they are so often resistant to change. These issues are discussed in this article, along with the role that social dilemmas play in inhibiting individually prosocial behavior. (shrink)

Lifelines mounts a vigorous attack on sociobiology on the utterly mistaken grounds that sociobiologists believe that genes single-handedly determine social behavior. The many previously published rebuttals to this pernicious criticism are conveniently ignored by the author.

Policymakers who seek to make scientifically informed decisions are constantly confronted by scientific uncertainty and expert disagreement. This thesis asks: how can policymakers rationally respond to expert disagreement and scientific uncertainty? This is a work of non-ideal theory, which applies formal philosophical tools developed by ideal theorists to more realistic cases of policymaking under scientific uncertainty. I start with Bayesian approaches to expert testimony and the problem of expert disagreement, arguing that two popular approaches— supra-Bayesianism and the standard model of (...) expert deference—are insufficient. I develop a novel model of expert deference and show how it can deal with many of these problems raised for them. I then turn to opinion pooling, a popular method for dealing with disagreement. I show that various theoretical motivations for pooling functions are irrelevant to realistic policymaking cases. This leads to a cautious recommendation of linear pooling. However, I then show that any pooling method relies on value judgements, that are hidden in the selection of the scoring rule. My focus then narrows to a more specific case of scientific uncertainty: multiple models of the same system. I introduce a particular case study involving hurricane models developed to support insurance decision-making. I recapitulate my analysis of opinion pooling in the context of model ensembles, confirming that my hesitations apply. This motivates a shift of perspective, to viewing the problem as a decision theoretic one. I rework a recently developed ambiguity theory, called the confidence approach, to take input from model ensembles. I show how it facilitates the resolution of the policymaker’s problem in a way that avoids the issues encountered in previous chapters. This concludes my main study of the problem of expert disagreement. In the final chapter, I turn to methodological reflection. I argue that philosophers who employ the mathematical methods of the prior chapters are modelling. Employing results from the philosophy of scientific models, I develop the theory of normative modelling. I argue that it has important methodological conclusions for the practice of formal epistemology, ruling out popular moves such as searching for counterexamples. (shrink)

abstract: Moral autonomy might seem to harbor inconsistency. Whereas nomos suggests that moral laws are grounded in our essence or nature (and thus are not up to us), autos suggests that they are grounded in some free act of self-legislation or prescription (and thus are up to us). Latter-day Kantians often respond by compromising on autonomy, deflating either nomos or autos. This investigation reconstructs how Christian Wolff, Kant’s great rationalist predecessor, already forged a path for embracing autonomy without compromise. His (...) reconciliation, I argue, rests on distinguishing different respects in which moral laws stand in need of grounding. I further unravel why no parallel reconciliation is found in Kant. This, I conclude, still leaves open that Kant may similarly seek to embrace autonomy without compromise. (shrink)

My first plea has to do with the adequacy of this approach for the diverse purposes that philosophers set out for conceptual analysis. It is unclear what to make of concepts that do not lend themselves to obvious analysis in terms of the sorts of benefits that motivate Fisher’s intuitive cases. Some of the central concepts of philosophy — just the ones that where conceptual analysis ought to be most at home — like Knowledge or Person or Just State are (...) not ones where the benefit of determining whether something falls under that concept is as direct as Fisher’s intuitive case suggests. Indeed, in the case of Knowledge, for instance, it is not clear that there is much benefit at all in determining whether something falls under the concept. My sense is that the benefit of philosophical concepts is in their role in a much larger framework of understanding our humanity. That 1 framework has some currency to philosophers, and perhaps there can be some abstract assignment of benefit to the conceptual joints of that framework, but it seems more like the benefit is in the holistic aspects of the framework. If this is right, then the benefit afforded by the individual concepts is going to be massively indirect. The problem appears to be that, for some concepts, PCA’s premier virtue begins to look like a vice. Fisher says, Our explication of concept-meaning will determine which meanings we attribute to various first-order concepts, and that, in turn, will guide our application of those concepts. …[W]e need an explication that will attribute to each concept a meaning that, if employed as application conditions for that concept, would do well to sustain the regular ways in which that concept has been beneficially used (p. 9).

Ascent: Philosophy and Paradise Lost, by ZamirTzachi. Oxford: Oxford University Press, 2018. Pp. 216.

THIS ESSAY CONSIDERS THE ROLE OF THE PROPHET IN CONTEMPORARY public policy debate. After identifying some problems that contemporary appeals to the prophets often encounter, the essay moves into an analysis of the Babylonian and Egyptian contexts out of which the Israelites and the Hebrew prophets emerged. A consideration of all three contexts shows that the central prophetic concern is a disruption of the divinely established social order that is most clearly indicated by the rich getting richer at the expense (...) of the poor. The essay then explores how this prophetic context can be understood in light of ethical appeals to the common good. Finally, the essay applies the notion of disruption in the social order to two issues of public policy: affordable housing and the stock market. (shrink)

The indispensability argument is a method for showing that abstract mathematical objects exist. Various versions of this argument have been proposed. Lately, commentators seem to have agreed that a holistic indispensability argument will not work, and that an explanatory indispensability argument is the best candidate. In this paper I argue that the dominant reasons for rejecting the holistic indispensability argument are mistaken. This is largely due to an overestimation of the consequences that follow from evidential holism. Nevertheless, the holistic indispensability (...) argument should be rejected, but for a different reason —in order that an indispensability argument relying on holism can work, it must invoke an unmotivated version of evidential holism. Such an argument will be unsound. Correcting the argument with a proper construal of evidential holism means that it can no longer deliver mathematical Platonism as a conclusion: such an argument for Platonism will be invalid. I then show how the reasons for rejecting the holistic indispensability argument importantly constrain what kind of account of explanation will be permissible in explanatory versions. (shrink)

The Quest for Learning: How to Maximize Student Engagement affirms that traditional classroom learning experiences, in which you plan lessons and voice instruction at the front of the room, do not meet 21st century students learning needs. Questing is a customizable pedagogy that readers and their students together tailor to a students abilities, needs, and interests. Side by side, and aligned with learning targets, readers learn how teachers and students determine what a student will learn about and at what pace. (...) Authors Marie Alcock, Michael Fisher, and Allison Zmuda propose three tenets of engagement (1) the learner engages with relevant, worthy inquiries and experiences that are interesting or emotionally gripping, (2) the learner engages in an active, intentional cycle with clear goals and right-sized, actionable steps, and (3) the learner engages in social, collaborative opportunities that grow expertise that allow students to take ownership of their learning. To further that ownership, students decide which design type they want to use to explore their quest topic (1) question, (2) game, or (3) network. Students then pursue lines of inquiry, design or play games, or communicate with peers and experts in online and physical spaces. Each is a method for becoming an expert on chosen topics. (shrink)

The global pandemic and resultant lockdowns are challenging our traditional assumptions about the times and spaces of labour and leisure - but how were these norms established and why have they had such an enduring appeal? In this paper, we take a long view to investigate the philosophical and historical roots of the binary distinction between work and play and outline ways in which these long-held ideas are being increasingly challenged. As lockdown measures are relaxed, we urgently need to develop (...) more nuanced conceptions of the spatial and temporal conditions of work and leisure to ensure a more equitable and compassionate post-lockdown world.

Kant views every human action as either entirely determined by natural necessity or entirely free. In viewing human action this way, it is unclear how he can account for degrees of responsibility. In this article, I consider three recent attempts to accommodate degrees of responsibility within Kant's framework, but argue that none of them are satisfying. In the end, I claim that transcendental idealism constrains Kant such that he cannot provide an adequate account of degrees of responsibility.

Although widely accepted to be the capacity to exercise control in one’s learning, there remains confusion about what exactly this means. Failure to reconcile contradictions has left the field resigned to pluralism, describing ‘versions’ of learner autonomy according to divergent theoretical orientations. However, each version is incomplete, rendering it unreliable as a basis for practice: educational initiatives that seek to foster learner autonomy from one perspective, run the risk of inadvertently undermining it from another. In an attempt to rectify this, (...) I turn to philosophies of personal autonomy, which I analyse in relation to learner autonomy to identify criteria for its achievement, regardless of version. If we acknowledge that learners are ever embodied, emplaced and sociohistorically situated, as we must, learning is a process of identity construction in relation to context. To be in control of this process is to define ourselves in terms of authentic values, the expression of which may require resolve to stay one’s path or resistance to pressure to act otherwise, all of which is contingent on affordances and constraints that are inherent to our embodied, emplaced and sociohistorical constitution. I examine the implications of this theory for practice within educational institutions. (shrink)

What norm governs how an agent should change their beliefs when they encounter a completely new possibility? Orthodox Bayesianism has no answer, as it takes all learning to involve updating prior beliefs. A partial proposal is Reverse Bayesianism, which mandates the preservation of ratios of prior probabilities, but it faces counterexamples introduced by Mahtani (2021). I propose to separate awareness growth into two stages: awareness revision and belief extension. I argue that Mahtani’s cases highlight that we need to theorize awareness (...) revision before we can define a proposal for belief extension, such as Reverse Bayesianism. I provide a formal model of awareness revision which makes explicit how propositions are distinguished within awareness states and identified across them. Reformulating Reverse Bayesianism to take input from my model allows it to navigate Mahtani-style cases. My model leaves open how agents choose to identify propositions across awareness states, and I propose that they ought to do so conservatively: preserving undisturbed prior reasoning about the structure of their awareness. I then spell out this proposal in a special case. This is a partial proposal, and I close with a discussion of how to elaborate on it and how to advance research into awareness revision. (shrink)

The subject of this book is young children's emotional-social learning and development within early childhood care and education settings in Aotearoa-New Zealand. The focus on emotional complexity fills a gap in early childhood care and education research where young children are frequently framed narrowly as 'learners,' ignoring the importance of emotional functioning and the feelings with which children make sense of themselves and the world. This book draws on original data in the form of narrative-like framed events to creatively illustrate (...) the complexities in children's diverse ways of feeling, thinking, playing, being, and becoming. Events illuminate the feelings and meanings of observed experiences in holistic and contextualised gestalts. Awareness of unconscious processes, the feeling of feelings, and cultural dimensions of development and meaning-making are addressed. The book emphasises the emergent and psychodynamic nature of children's development and learning with strong links to the role of play and playfulness in the events, drawing on two ethnographically inspired research projects that present theory, experience and practice in real-life events.

Lacan, qui a prôné le "retour à Freud", qui s'est donc voulu le défenseur strict de la cause freudienne, ne s'est jamais réclamé que de la psychanalyse. Il a cependant beaucoup fréquenté les philosophes : non seulement Hegel à travers la lecture de Kojève, mais aussi et surtout Bataille et Heidegger, deux auteurs dont il a été, on le sait aujourd'hui, intellectuellement très proche. Cette profonde influence sur son oeuvre pose alors la question de savoir s'il serait possible de proposer (...) une interprétation philosophique de celle-ci. Pourrait-t-on développer une philosophie lacanienne? Ce livre s'efforce de montrer qu'une telle lecture de la pensée lacanienne est non seulement concevable, mais que la possibilité en a été indiquée par Lacan lui-même, en particulier dans le Séminaire VII, bien qu'il ne s'y soit jamais engagé pleinement. Il apparaîtra alors qu'une telle interprétation de Lacan, qui va au-delà de la lettre de sa pensée mais ne la trahit pas et qui est même autorisée par la richesse et la complexité de l'oeuvre, ouvre non seulement des perspectives nouvelles sur celle-ci, mais subvertit totalement les présupposés qui portent la philosophie traditionnelle depuis ses origines. Que pourrait être, finalement, le lacanisme en philosophie? Telle est donc la question à laquelle cet essai tente de répondre. (shrink)

The United States is on a path of increasing social conflict, accentuated class, and racial inequalities. Based on a belief that change can be brought about by citizen action, this volume argues that such action can be assisted by what the authors call "liberation sociology"--A tool for the increase of democratic participation in the production and implementation of knowledge.

Since the publication of David Lewis’ Counterfactuals, the standard line on subjunctive conditionals with impossible antecedents (or counterpossibles) has been that they are vacuously true. That is, a conditional of the form ‘If p were the case, q would be the case’ is trivially true whenever the antecedent, p, is impossible. The primary justification is that Lewis’ semantics best approximates the English subjunctive conditional, and that a vacuous treatment of counterpossibles is a consequence of that very elegant theory. Another justification (...) derives from the classical lore than if an impossibility were true, then anything goes. In this paper we defend non-vacuism, the view that counterpossibles are sometimes non-vacuously true and sometimes non-vacuously false. We do so while retaining a Lewisian semantics, which is to say, the approach we favor does not require us to abandon classical logic or a similarity semantics. It does however require us to countenance impossible worlds. An impossible worlds treatment of counterpossibles is suggested (but not defended) by Lewis (Counterfactuals. Blackwell, Oxford, 1973), and developed by Nolan (Notre Dame J Formal Logic 38:325–527, 1997), Kment (Mind 115:261–310, 2006a: Philos Perspect 20:237–302, 2006b), and Vander Laan (In: Jackson F, Priest G (eds) Lewisian themes. Oxford University Press, Oxford, 2004). We follow this tradition, and develop an account of comparative similarity for impossible worlds. (shrink)

Recently, a few attempts have been made to rehabilitate satisficing consequentialism. One strategy, initially shunned by Tim Mulgan, is to suggest that agents must produce an outcome at least as good as they could at a particular level of effort. The effort-satisficer is able to avoid some of the problem cases usually deemed fatal to the view. Richard Yetter Chappell has proposed a version of effort-satisficing that not only avoids those problem cases, but has some independent plausibility. In this paper, (...) I argue that we should be concerned by verdicts the effort-satisficer delivers that are too permissive. Revising a problem for the traditional outcome-satisficer, I argue that Chappell’s willpower satisficing, and more generally, any effort-satisficer, must implausibly condone murder in many cases. This seems like a serious issue for any attempts at rehabilitating satisficing consequentialism in this way. After presenting my objection, I consider some ways an effort-satisficer might attempt to revise the account to avoid these problems, but argue that none of these can succeed. (shrink)

There has recently been an explosion of interest in rational and moral choice under evaluative uncertainty—uncertainty about values or reasons. However, the dominant views on such choice have at least three major problems: they are overly demanding, they are incompatible with supererogation, and they cannot be applied to agents with credence in indeterminate evaluative theories. The authors propose a unified view that solves all these problems. According to this view, permissible options maximize expected utility relative to permissible preferences, and different (...) kinds of permissibility for options correspond to different kinds of permissibility for preferences. Thus, rationally permissible options maximize expected utility relative to rationally permissible preferences, and morally permissible options maximize expected utility relative to morally permissible preferences. The authors argue that this view has more plausible implications than its rivals not only under evaluative uncertainty but also under ordinary uncertainty. (shrink)

Is there any number of people you should save from paralysis rather than saving one person from death? Is there any number of people you should save from a headache rather than saving one person from death? Many people answer ‘yes’ and ‘no’, respectively. They therefore accept a partially aggregative moral view. Patrick Tomlin has recently argued that the most promising partially aggregative views in the literature have implausible implications in certain cases in which there are additions or subtractions to (...) the groups of people that we can save. Several philosophers have begun responding to this argument by developing partially aggregative views that avoid the relevant implications. In this paper, I extend Tomlin’s argument to create a dilemma that no partially aggregative view can avoid. I conclude that we should accept a fully aggregative moral view. (shrink)

This chapter examines modal modelling in climate science. It considers two related topics. The first is the use of climate models to attribute extreme weather events to climate change. The second is the interpretation and use of collections of climate models. Each topic is the subject of a current debate within climate science and philosophy of science, and each has an important modal component. The debates are similar in that each involves a contrast between probabilistic and non-probabilistic methods. In each (...) case, the chapter examines the kind of modal claims scientists make and how they are justified. As climate change is an important practical problem, each debate has a link to policy decisions, and so the chapter ends with a discussion of how modal modelling, and the possibilities it identifies, can support decision-making.

Ralph Ellison’s _Invisible Man_ is a violent text. It is unflinching in its confrontation with the violence at the heart of the (African-)American experience. In exploring the central role of violence here – narratively, within the novel; politically, within the culture that the novel explores – the recent work of Slavo Zizek is useful. Zizek posits a critical language which makes an important distinction between systemic violence (of the order of economic and political systems), objective violence (of the order of (...) discriminatory patterns of behaviour), and subjective violence (of the order of individual, often spontaneous, sometimes self-directed acts – which have the effect of misdirecting and obscuring our awareness of these other two more insidious forms of violence). And, in a dialectical spirit of which both Zizek and Ellison might approve, _Invisible Man_ will here reciprocally suggest an interrogation of Zizek’s theories of revolutionary violence. (shrink)

Let me begin by signaling my enthusiasm both for the specific case offered by Cummins et al. against teleosemantics and for the overall framework from which this work derives. If the first approximation of the idea is that there will be material implicit in a representation that can be exploited by a cognitive agent that later acquires the right abilities to extract this material, and if this material looks a great deal like content, then the teleosemanticist will find accommodating it (...) challenging. Moreover, the distinction between representation and indication is intriguing and important, and the discussion of structural transformation and isomorphism is illuminating. While Cummins has been urging these themes for some time now, it seems to me that they have not been sufficiently appreciated in the literature. (shrink)
