Growing-Block theorists hold that past and present things are real, while future things do not yet exist. This generates a puzzle: how can Growing-Block theorists explain the fact that some sentences about the future appear to be true? Briggs and Forbes develop a modal ersatzist framework, on which the concrete actual world is associated with a branching-time structure of ersatz possible worlds. They then show how this branching structure might be used to determine the truth values of future contingents. They (...) point out three different ways of interpreting the logical connectives, which give rise to three different logics of the open future: one supervaluationist, one corresponding to Lukasiewicz's strong Kleene logic, and one intuitionist.

Face perception is a highly conserved process that directs our attention from infancy and is supported by specialized neural circuitry. Oxytocin can increase accuracy and detection of emotional faces, but these effects are mediated by valence, individual differences, and context. We investigated the temporal dynamics of oxytocin’s influence on the neural substrates of face perception using event related potentials (ERP). In a double blind, placebo controlled within-subject design, 21 healthy male adults inhaled oxytocin or placebo and underwent ERP imaging during (...) two face processing tasks. Experiment 1 investigated effects of oxytocin on neural correlates of fearful versus neutral facial expressions, and Experiment 2 manipulated point-of-gaze to neutral faces. In Experiment 1, we found that oxytocin reduced N170 latency to fearful faces. In Experiment 2, N170 latency was decreased when participant gaze was directed to the eyes of neutral faces; however, there were no oxytocin-associated effects in response to different facial features. Findings suggest oxytocin modulates early stages of social perception for socially complex information such as emotional faces relative to neutral. These results are consistent with models suggesting oxytocin impacts the salience of socially informative cues during processing, which leads to downstream effects in behavior. Future work should examine how oxytocin affects neural processes underlying basic components of social behavior (such as, face perception) while varying emotional expression of stimuli or comparing different characteristics of participants (e.g., gender, personality traits).

Diachronic Dutch book arguments seem to support both conditionalization and Bas van Fraassen's Reflection principle. But the Reflection principle is vulnerable to numerous counterexamples. This essay addresses two questions: first, under what circumstances should an agent obey Reflection, and second, should the counterexamples to Reflection make us doubt the Dutch book for conditionalization? In response to the first question, this essay formulates a new "Qualified Reflection" principle, which states that an agent should obey Reflection only if he or she is (...) certain that he or she will conditionalize on veridical evidence in the future. Qualified Reflection follows from the probability calculus together with a few idealizing assumptions. The essay then formulates a "Distorted Reflection" principle that approximates Reflection even in cases where the agent is not quite certain that he or she will conditionalize on veridical evidence. In response to the second question, the essay argues that contrary to a common misconception, not all Dutch books dramatize incoherence—some dramatize a less blameworthy sort of epistemic frailty that the essay calls "self-doubt." The distinction between Dutch books that dramatize incoherence and those that dramatize self-doubt cross-cuts the distinction between synchronic and diachronic Dutch books. The essay explains why the Dutch book for conditionalization reveals true incoherence, whereas the Dutch book for Reflection reveals only self-doubt. (shrink)

We calculate the complexity of Scott sentences of scattered linear orders. Given a countable scattered linear order L of Hausdorff rank $\alpha $ we show that it has a ${d\text {-}\Sigma _{2\alpha +1}}$ Scott sentence. It follows from results of Ash [2] that for every countable $\alpha $ there is a linear order whose optimal Scott sentence has this complexity. Therefore, our bounds are tight. We furthermore show that every Hausdorff rank 1 linear order has an optimal ${\Pi ^{\mathrm {c}}_{3}}$ (...) or ${d\text {-}\Sigma ^{\mathrm {c}}_{3}}$ Scott sentence and give a characterization of those linear orders of rank $1$ with ${\Pi ^{\mathrm {c}}_{3}}$ optimal Scott sentences. At last we show that for all countable $\alpha $ the class of Hausdorff rank $\alpha $ linear orders is $\boldsymbol {\Sigma }_{2\alpha +2}$ complete and obtain analogous results for index sets of computable linear orders.

In recent years, the concept of evolvability has been gaining in prominence both within evolutionary developmental biology (evo-devo) and the broader field of evolutionary biology. Despite this, there remains considerable disagreement about what evolvability is. This article offers a solution to this problem. I argue that, in focusing too closely on the role played by evolvability as an explanandum in evo-devo, existing philosophical attempts to clarify the evolvability concept have been overly narrow. Within evolutionary biology more broadly, evolvability offers a (...) robust explanation for the evolutionary trajectories of populations. Evolvability is an abstract, robust, dispositional property of populations, which captures the joint causal influence of their internal features on the outcomes of evolution (as opposed to the causal influence of selection, which is often characterized as external). When considering the nature of the physical basis of this disposition, it becomes clear that the many existing definitions of evolvability at play within evo-devo should be understood as capturing only aspects of a much broader phenomenon. 1 Introduction2 The Problem of Evolvability3 The Theoretical Role of Evolvability in Evolutionary Biology 3.1 The explanatory targets of evolutionary biology 3.2 Selection-based explanations 3.3 Lineage explanations 3.4 Evolvability-based explanations 3.5 What properties must evolvability have?4 What Evolvability Really Is 4.1 Making sense of ft 4.2 Making sense of x and b5 What of the Limbs?

Risk-weighted expected utility theory permits preferences which violate the Sure-Thing Principle. But preferences that violate the STP can lead to bad decisions in sequential choice problems. In particular, they can lead decision-makers to adopt a strategy that is dominated – i.e. a strategy such that some available alternative leads to a better outcome in every possible state of the world.

It is a platitude among decision theorists that agents should choose their actions so as to maximize expected value. But exactly how to define expected value is contentious. Evidential decision theory (henceforth EDT), causal decision theory (henceforth CDT), and a theory proposed by Ralph Wedgwood that this essay will call benchmark theory (BT) all advise agents to maximize different types of expected value. Consequently, their verdicts sometimes conflict. In certain famous cases of conflict—medical Newcomb problems—CDT and BT seem to get (...) things right, while EDT seems to get things wrong. In other cases of conflict, including some recent examples suggested by Andy Egan, EDT and BT seem to get things right, while CDT seems to get things wrong. In still other cases, EDT and CDT seems to get things right, while BT gets things wrong. It's no accident, this essay claims, that all three decision theories are subject to counterexamples. Decision rules can be reinterpreted as voting rules, where the voters are the agent's possible future selves. The problematic examples have the structure of voting paradoxes. Just as voting paradoxes show that no voting rule can do everything we want, decision-theoretic paradoxes show that no decision rule can do everything we want. Luckily, the so-called “tickle defense” establishes that EDT, CDT, and BT will do everything we want in a wide range of situations. Most decision situations, this essay argues, are analogues of voting situations in which the voters unanimously adopt the same set of preferences. In such situations, all plausible voting rules and all plausible decision rules agree. (shrink)

We define the Scott complexity of a countable structure to be the least complexity of a Scott sentence for that structure. This is a finer notion of complexity than Scott rank: it distinguishes between whether the simplest Scott sentence is $\Sigma _{\alpha }$, $\Pi _{\alpha }$, or $\mathrm {d-}\Sigma _{\alpha }$. We give a complete classification of the possible Scott complexities, including an example of a structure whose simplest Scott sentence is $\Sigma _{\lambda + 1}$ for $\lambda $ a limit (...) ordinal. This answers a question left open by A. Miller.We also construct examples of computable structures of high Scott rank with Scott complexities $\Sigma _{\omega _1^{CK}+1}$ and $\mathrm {d-}\Sigma _{\omega _1^{CK}+1}$. There are three other possible Scott complexities for a computable structure of high Scott rank: $\Pi _{\omega _1^{CK}}$, $\Pi _{\omega _1^{CK}+1}$, $\Sigma _{\omega _1^{CK}+1}$. Examples of these were already known. Our examples are computable structures of Scott rank $\omega _1^{CK}+1$ which, after naming finitely many constants, have Scott rank $\omega _1^{CK}$. The existence of such structures was an open question. (shrink)

A number of recent authors (Galles and Pearl, Found Sci 3 (1):151–182, 1998; Hiddleston, Noûs 39 (4):232–257, 2005; Halpern, J Artif Intell Res 12:317–337, 2000) advocate a causal modeling semantics for counterfactuals. But the precise logical significance of the causal modeling semantics remains murky. Particularly important, yet particularly under-explored, is its relationship to the similarity-based semantics for counterfactuals developed by Lewis (Counterfactuals. Harvard University Press, 1973b). The causal modeling semantics is both an account of the truth conditions of counterfactuals, and (...) an account of which inferences involving counterfactuals are valid. As an account of truth conditions, it is incomplete. While Lewis's similarity semantics lets us evaluate counterfactuals with arbitrarily complex antecedents and consequents, the causal modeling semantics makes it hard to ascertain the truth conditions of all but a highly restricted class of counterfactuals. I explain how to extend the causal modeling language to encompass a wider range of sentences, and provide a sound and complete axiomatization for the extended language. Extending the truth conditions for counterfactuals has serious consequences concerning valid inference. The extended language is unlike any logic of Lewis's: modus ponens is invalid, and classical logical equivalents cannot be freely substituted in the antecedents of conditionals. (shrink)

The fearful ape hypothesis proposes that heightened fearfulness in humans is adaptive. However, despite its attractive anthropocentric narrative, the evidence presented for greater fearfulness in humans versus other apes is not sufficient to support this claim. Conceptualization, context, and comparison are strongly lacking in Grossmann's proposal, but are key to understanding variation in the fear response among individuals and species.

Against the background of “arms race” style competitive explanations for complex human cognition, such as the Social Intelligence Hypothesis Growing points in ethology, Cambridge University Press, pp 303–317, 1976; Jolly in Science, 10.1126/science.153.3735.501, 1966), and theories that tie complex cognition with environmental variability more broadly The evolution of intelligence, Lawrence Earlbaum and Associates, 2001), the idea that culturally inherited mechanisms for social cognition would be more capable of responding to the labile social environment is a compelling one. Whilst it is (...) tempting to think that the evolvability of culturally inherited cognitive mechanisms such as Cecilia Heyes’ cognitive gadgets would be akin to culturally inherited tools like axes or canoes, I draw on established theory in evolutionary developmental biology to show that this is a mistake. Their causal translucency, along with the degree to which they would be integrated within the organism, make cognitive gadgets far more like genetically inherited traits with respect to their evolvability. Consequently, their evolution is unlikely to be particularly fast or nimble. In making clear the constraints on the evolution of culturally inherited cognition and how they must influence our theorising the discussion also highlights the value of thinking about evolvability in this domain.

Deaf or hard-of-hearing children who use auditory-oral communication display considerable variability in spoken language and executive functioning outcomes. Furthermore, language and executive functioning skills are strongly associated with each other in DHH children, which may be relevant for explaining this variability in outcomes. However, longitudinal investigations of language and executive functioning during the important preschool period of development in DHH children are rare. This study examined the predictive, reciprocal associations between executive functioning and spoken language over a 1-year period in (...) samples of 53 DHH and 59 typically hearing children between ages 3–8 years at baseline. Participants were assessed on measures of receptive spoken language and caregiver-completed executive functioning child behavior checklists during two in-person home visits separated by 1 year. In the sample of DHH children, better executive functioning at baseline was associated with better performance on the higher-order language measures 1 year later. In contrast, none of the Time 1 language measures were associated with better executive functioning in Time 2 in the DHH sample. TH children showed no significant language-executive functioning correlations over the 1-year study period. In regression analyses controlling for Time 1 language scores, Time 1 executive functioning predicted Time 2 language outcomes in the combined DHH and TH samples, and for vocabulary, that association was stronger in the DHH than in the TH sample. In contrast, after controlling for Time 1 executive functioning, none of the regression analyses predicting Time 2 executive functioning from Time 1 language were statistically significant. These results are the first findings to demonstrate that everyday parent-rated executive functioning behaviors predict basic and higher-order spoken language development 1 year later in young DHH children, even after accounting for initial baseline language skills.

The historical figure of the cow as a symbol is treasured and ancient, yet simultaneously this animal in many societies exists de facto for people’s plates. The cow, like other animals, exists in parts: as treasured symbol, and as commodity. Looking at collections by contemporary Anglophone poets, Ariana Reines, and Selima Hill, I will consider how each writer’s self-reflexive critique of animal representation reorients the material subjects of their poems, intersecting these innovative poetries with contemporary thinkers on animal studies, to (...) realize the limits of a poetic perspective on animal bodies. Both writers work either against or deliberately within a lyric mode critiqued for its objectifying address in order to interrogate modes of rendering that position the animal’s existence as a resource. From Reines’s scatological slaughterhouse to Hill’s surreal landscapes I will explore how the symbolic and literal exploitation of an animal’s “flesh” in their poems is counteracted. (shrink)

A recent report by Blumenthal et al.1 provides convincing evidence that at least 15% of Caenorhabditis elegans genes are co‐transcribed within over a thousand operons. Polycistronic transcription of gene clusters is very rare in eukaryotes. The widespread occurrence of operons in C. elegans thus raises some interesting questions about the origin and function of these multigenic transcriptional units.

Veissière et al. must sacrifice explanatory realism and precision in order to develop a unified formal model. Drawing on examples from cognitive archeology, we argue that this makes it difficult for them to derive the kinds of testable predictions that would allow them to resolve debates over the nature of human social cognition and cultural acquisition.

Interest in universal basic income has risen recently as an alternative to existing exchequer-sourced social security methods, such as conditional cash transfers. This article presents a survey of multiple experiments investigating the impact of basic income cash transfers on recipients while presenting a meta-analysis of the results across nine categories. Many findings indicate successful outcomes across financial security, health, and educational dimensions. Children were amongst the strongest beneficiaries of the trials and observed a 4.5 % reduction in obesity, a 19.5 (...) % increase in their normal weight-for-age, a 30 % increase in female secondary school attendance, and an increase in the educational attainment of one year in response to the cash transfers.

We improve on and generalize a 1960 result of Maltsev. For a field F, we denote by $H(F)$ the Heisenberg group with entries in F. Maltsev showed that there is a copy of F defined in $H(F)$, using existential formulas with an arbitrary non-commuting pair of elements as parameters. We show that F is interpreted in $H(F)$ using computable $\Sigma _1$ formulas with no parameters. We give two proofs. The first is an existence proof, relying on a result of Harrison-Trainor, (...) Melnikov, R. Miller, and Montalbán. This proof allows the possibility that the elements of F are represented by tuples in $H(F)$ of no fixed arity. The second proof is direct, giving explicit finitary existential formulas that define the interpretation, with elements of F represented by triples in $H(F)$. Looking at what was used to arrive at this parameter-free interpretation of F in $H(F)$, we give general conditions sufficient to eliminate parameters from interpretations. (shrink)

We ask when, for a pair of structures $\mathcal {A}_1,\mathcal {A}_2$, there is a uniform effective procedure that, given copies of the two structures, unlabeled, always produces a copy of $\mathcal {A}_1$. We give some conditions guaranteeing that there is such a procedure. The conditions might suggest that for the pair of orderings $\mathcal {A}_1$ of type $\omega _1^{CK}$ and $\mathcal {A}_2$ of Harrison type, there should not be any such procedure, but, in fact, there is one. We construct an (...) example for which there is no such procedure. The construction involves forcing. On the way to constructing our example, we prove a general result on modifying Cohen generics.

I propose an account truthmaking that provides truthmakers for negative truths.

My account captures an intuitive notion of truthmakers as "things the way they are", validates two appealing principles about (...) entailment and containment proposed by David Armstrong, and invalidates the controversial Disjunction Thesis.

Evidence exists that the UK National Health Service has had, over many years, persistent problems of negative and intimidating behaviour towards staff from other employees. The evidence also suggests the organisational responses to negative behaviour can be inadequate. A conceptual model of organisational dysfunction was proposed to assist in explaining those responses and the overall culture in the NHS. Through research this model has been tested. Based upon the findings, an extended and developed model of organisational dysfunction is presented. A (...) qualitative approach was taken to research the organisational responses to negative behaviour, and the reasons and motivations for those responses. Forty-three interviews and six focus groups were conducted. There seem to be “islands” and “pockets” with a positive culture; however, the generalised evidence suggests the NHS is systemically and institutionally deaf, bullying, defensive and dishonest, exhibiting a resistance to ‘knowing’, denial and “wilful blindness”; a dysfunctional, perverse and troubled organisation. Totalitarian and Kafkaesque characteristics are identified. The NHS could also be described as a coercive bureaucracy and under certain definitions, a corrupt entity. The NHS appears to be an organisation with a heart of darkness; a “self perpetuating dysfunctional system”. There may be widespread “learned helplessness”. It seems to be a “good news factory”, rejecting and hiding any “bad news”; retreating from reality. The NHS appears to have “lost its way” and its focus/purpose as an institution. The dysfunctional organisational behaviours manifest in the NHS need to be addressed urgently as there is a detrimental, sometimes devastating, impact on the wellbeing of both staff and patients. The NHS needs to embrace an identity of being a listening, learning and honest organisation, with a culture of respect. (shrink)

The rules governing recovery for negligently inflicted psychiatric injury are among the most criticized of all of tort law. However, one area which, to date, has escaped with a minimum of judicial or academic scrutiny concerns the very threshold requirement for these actions: proof of a ‘recognized psychiatric illness’. This article critiques that longstanding requirement of English law from two perspectives. First, it is argued that the international classifications of psychiatric disorders (ICD-10 and DSM-IV) are being misapplied and misconstrued in (...) the English medico-legal context and that the role (and limitations) of these classifications are worthy of far greater judicial examination and critical scrutiny than has typically been the case to date. Secondly, it is contended that the insistence upon a recognized psychiatric illness, as a threshold requirement, is giving rise to inconsistencies and distortions in the law and that the requirement is neither legally nor medically supportable in the modern era. Instead, it is argued that the stage has been reached whereby something lesser than a recognized psychiatric illness should be sufficient to trigger a compensable injury in law. The article concludes by suggesting various legal avenues by which to feasibly and robustly ‘ring-fence’ the number of potential claims in negligence, should the reform-oriented approach of this article be adopted.

Non‐human animal evidence is frequently invoked in debates in cognitive science. Here, I critically assess one use of such evidence in the form of the “argument from animals,” a prominent positive argument for nativism, which roughly states that non‐human cognitive development is largely nativist, and thus human cognitive development is most likely largely nativist too. I offer a number of reasons to reject this argument, and in doing so derive some important broader lessons concerning the appropriate role of non‐human animal (...) evidence in a science of the human mind.

Although there is no in-principle impediment to an EvoDevo of behavior, such an endeavor is not as straightforward as one might think; many of the key terms and concepts used in EvoDevo are tailored to suit its traditional focus on morphology, and are consequently difficult to apply to behavior. In this light, the application of the EvoDevo conceptual toolkit to the behavioral domain requires the establishment of a set of tractable concepts that are readily applicable to behavioral characters. Here, I (...) begin the type of theoretical work that needs to be undertaken in order to achieve this, focusing in particular on the key concept of “novelty.” Building on existing criteria used for the identification of behavioral homology from behavioral ecology, I develop a set of operational criteria for identifying novelty in the behavioral domain. These criteria provide a conceptual foundation for the study of novelty in behavioral traits. (shrink)

Bilingualism is a valuable tool that enriches and facilitates cultural, social and lived experiences for autistic and non-autistic people alike. Research consistently finds no negative effects of bilingualism and highlights the potential for positive effects across cognitive and socio-cultural domains for autistic and non-autistic children. Yet parents of autistic children remain concerned that bilingualism will cause delays in both cognitive and language development and are still frequently advised by practitioners to raise their child monolingually. Evidently, findings from research are not (...) reflected in practice or subsequent advice, and it is essential to identify ways to ensure equal access to additional language learning. We briefly summarise the existing literature on bilingualism and autism, considering perspectives from the bilingual autistic community, and experimental research. We identify the most pertinent barriers to participation for autistic bilingual children in terms of familial, clinical and educational perspectives. We propose novel solutions to promote additional language learning and suggest changes to practice that will contribute to an evidence base for families and practitioners. This commentary makes innovative recommendations at both the individual and societal level to ensure that autistic bilingual people have equal rights and opportunities to language learning and are optimally supported in accessing them.

Modern literature has always been obsessed by music. It cannot seem to think about itself without obsessing about music. And music has returned the favour. The Routledge Companion to Music and Modern Literature addresses this relationship as a significant contribution to the burgeoning field of word and music studies.

This Companion therefore offers an essential resource for all who try to decode the musico-literary exchange. (shrink)

I consider an old problem for preference satisfaction theories of wellbeing: that they have trouble answering questions about interpersonal comparisons, such as whether I am better off than you are, or whether a particular policy benefits me more than it benefits you.

Metaphysicians are in the business of making and defending modal claims—claims about how things must, or could or could not be. Wittgenstein’s opposition to necessity claims, along with his various negative remarks about ‘metaphysical’ uses of language, makes it seem almost a truism that Wittgenstein was opposed to metaphysics. In this paper I want to make a case for rejecting that apparent truism. My thesis is that it is illuminating to characterize what Wittgenstein and Anscombe are doing in their philosophical (...) writing as metaphysics without manufactured necessities. Doing so helps to articulate a sharper, more interesting, critique of contemporary metaphysical practices than therapeutic or linguistic framings of Wittgenstein’s method make possible. It also allows us to place Anscombe in the context of a tradition of British metaphysics that emerged in the 1940s in an attempt to reverse the devastating impact on ethics of the new ‘analytical’ philosophy.

There is a deep connection between Anscombe’s argument that ‘I’ is not a referring expression and Intention’s account of practical knowledge and knowledge without observation. The assumption that the so-called “no-reference thesis” can be resisted while the account of action set out in her book INTENTION is embraced is based on a misunderstanding of the argument of “The First Person” and the status of its conclusion; removing that misunderstanding helps to illuminate the concept of practical knowledge and brings into view (...) a novel account of the relation between self-consciousness, agency, and first-person thought.

Third, can chance be reconciled with determinism, and if so, how? (shrink)

Traditional accounts of the role of learning in evolution have concentrated upon its capacity as a source of fitness to individuals. In this paper I use a case study from invasive species biology—the role of conditioned taste aversion in mitigating the impact of cane toads on the native species of Northern Australia—to highlight a role for learning beyond this—as a source of evolvability to populations. This has two benefits. First, it highlights an otherwise under-appreciated role for learning in evolution that (...) does not rely on social learning as an inheritance channel nor “special” evolutionary processes such as genetic accommodation (both of which many are skeptical about). Second, and more significantly, it makes clear important and interesting parallels between learning and exploratory behaviour in development. These parallels motivate the applicability of results from existing research into learning and learning evolution to our understanding of the evolution of evolvability more generally. (shrink)

The 1945 discovery of ancient documents at Nag Hammadi in Egypt would have great significance for New Testament scholars.

The meaning of intelligence has varied across time and place, with these varied constructions holding consequences for people and society at large. There is, however, little consensus around what intelligence actually means and how the construct should be applied. Educational discourses, including textbooks used to train teachers, have commonly been the site for the dissemination of ‘authoritative’ information surrounding intelligence. In this article, we present findings from a discourse analysis informed by discursive psychology of passages related to defining and measuring (...) intelligence taken from 10 educational psychology textbooks designed for university students studying to become teachers. Our research question was: How is the dilemmatic nature of the construct of intelligence managed in introductory educational psychology textbooks at the level of discourse? We discuss the function of sequencing and topic displays and how the textbook authors navigated the ideological dilemmas surrounding the construct of intelligence. We conclude by pointing to the implications for teacher training and the importance of social constructionist projects that place into question presumably ‘real’ psychological constructs. (shrink)
