I propose an account truthmaking that provides truthmakers for negative truths. The account replaces Truthmaker Necessitarianism with a "Duplication Principle", according to which a suitable entity T is a truthmaker for a proposition P just in case the existence of an appropriate counterpart of T entails the truth of P, where the counterpart relation is cashed out in terms of qualitative duplication. 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.

This article surveys several interrelated issues in the metaphysics of chance. First, what is the relationship between the probabilities associated with types of trials (for instance, the chance that a twenty‐eight‐year old develops diabetes before age thirty) and the probabilities associated with individual token trials (for instance, the chance that I develop diabetes before age thirty)? Second, which features of the the world fix the chances: are there objective chances at all, and if so, are there non‐chancy facts on which (...) they supervene? Third, can chance be reconciled with determinism, and if so, how? (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.

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)

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?

Successful behavior requires actively acquiring and representing information about the environment and people, and manipulating and using those acquired representations flexibly to optimally act in and on the world. The frontal lobes have figured prominently in most accounts of flexible or goal-directed behavior, as evidenced by often-reported behavioral inflexibility in individuals with frontal lobe dysfunction. Here, we propose that the hippocampus also plays a critical role by forming and reconstructing relational memory representations that underlie flexible cognition and social behavior. There (...) is mounting evidence that damage to the hippocampus can produce inflexible and maladaptive behavior when such behavior places high demands on the generation, recombination, and flexible use of information. This is seen in abilities as diverse as memory, navigation, exploration, imagination, creativity, decision-making, character judgments, establishing and maintaining social bonds, empathy, social discourse, and language use. Thus, the hippocampus, together with its extensive interconnections with other neural systems, supports the flexible use of information in general. Further, we suggest that this understanding has important clinical implications. Hippocampal abnormalities can produce profound deficits in real-world situations, which typically place high demands on the flexible use of information, but are not always obvious on diagnostic tools tuned to frontal lobe function. This review documents the role of the hippocampus in supporting flexible representations and aims to expand our understanding of the dynamic networks that operate as we move through and create meaning of our world.

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.

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)

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)

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.

Traditional ideas of mediator neutrality and impartiality have come under increasing attack in recent decades. There is, however, a lack of consensus on what should replace them. Mediation Ethics offers a response to this question, developing a new theory of mediation that emphasises its nature as a relational process.

One of the standard approaches to the metaphysics of personal identity has some counter‐intuitive ethical consequences when combined with maximising consequentialism and a plausible (though not uncontroversial) doctrine about aggregation of consequences. This metaphysical doctrine is the so‐called ‘multiple occupancy’ approach to puzzles about fission and fusion. It gives rise to a new version of the ‘utility monster’ problem, particularly difficult problems about infinite utility, and a new version of a Parfit‐style ‘repugnant conclusion’. While the article focuses on maximising consequentialism (...) for simplicity, the problems demonstrated apply more widely to a range of ethical views, especially flavours of consequentialism. This article demonstrates how these problems arise, and discusses a number of options available in the light of these problems for a consequentialist tempted by a multiple occupancy metaphysics.

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. I argue that a similar problem arises for intrapersonal comparisons in cases of transformative experience. I survey possible solutions to the problem, and point out some subtle disanalogies between the problem involving interpersonal comparisons and the problem involving transformative (...) experience.

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.

Tracking accounts of knowledge formulated in terms of counterfactuals suffer from well known problems. Examples are provided, and it is shown that moving to a dispositional tracking theory of knowledge avoids three of these problems.

Sidney Shoemaker credits Wittgenstein’s Blue Book with identifying a special kind of immunity to error that is characteristic of ‘I’ in its “use as subject”. This immunity to error is thought by Shoemaker, and by many following him, to be central to the meaning of ‘I’ and thus to the topics of self-knowledge, self-consciousness and personal memory. This paper argues that Wittgenstein’s work does not contain the thesis, nor any version of the thesis, that there is a use of ‘I’—‘use (...) as subject’—which is ‘immune to error through misidentification’. It offers an interpretative corrective and shows that the passage in question is part of a deep challenge to IEM and to accounts of first-person thought that begin with the idea that there are two uses of the word ‘I’. With the corrective in place novel perspectives on the relation between self-consciousness and subjectivity become visible. (shrink)

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)

In this article, we consider two independently appealing theories—the Growing-Block view and Humean Supervenience—and argue that at least one is false. The Growing-Block view is a theory about the nature of time. It says that past and present things exist, while future things do not, and the passage of time consists in new things coming into existence. Humean Supervenience is a theory about the nature of entities like laws, nomological possibility, counterfactuals, dispositions, causation, and chance. It says that none of (...) these entities are fundamental, since if they were, this would entail the existence of irreducible necessary connections between matters of fact. Instead, these entities supervene on a fundamental, non-nomological ‘Humean mosaic’ of property instances at spacetime points. We will further explain and motivate the Growing-Block view and Humean Supervenience in Sects. 2 and 3, but first, we turn to our master argument. (shrink)

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.

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.

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)

David Lewis claimed that deterministic chance was impossible. But deterministic chance seems ubiquitous in casinos, in statistical mechanics, and in evolutionary theory. It would be best for Lewis's metaphysics if, in spite of what he says, we could reconcile his core views with deterministic chance. In this chapter, the author briefly rebuts two Lewisian objections to deterministic chance. The first is that our world is indeterministic at the quantum level, and this lower‐level indeterminism translates to indeterminism at higher levels. The (...) chapter explains how deterministic chances are possible on a broadly Lewisian theory. It also explains how there can be deterministic chances that function as nomological magnitudes, guide credence, and arise in objectively chancy situations. It is true that the author's deterministic chances are not time‐indexed. It is also true that they do not exactly satisfy principles, proposed by Lewis and others in a broadly Lewisian tradition, that presuppose time‐indexing. (shrink)

Günter Wagner’s Homology, Genes, and Evolutionary Innovation is a compelling, and empirically well-supported account of the evolution of character identity and character origination which emphasizes the importance of homology and novelty as central explananda for 21st century evolutionary biology. In this essay review, I focus on the similarities and differences between the structuralist picture of evolutionary biology advocated by Wagner, and that presented by standard evolutionary theory. First, I outline the ways in which Wagner’s genetic theory of homology diverges from (...) the account of homology offered by standard evolutionary theory. Then, I consider the motivations for these divergences. Lastly, I discuss a number of concerns with Wagner’s view, and offer some concluding thoughts on the relationship between structuralism and adaptationism. (shrink)

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)

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)

Back in October 2015 I had the opportunity to chair the book launch for all three works discussed in this review essay. At the event, Shirley Anne Tate said, “Black feminist theory is the theory”. The comment referred to how it is not ‘just’ that Black feminist theory is typically marginalised within institutional contexts and academic scholarship, ‘even’ within critical, feminist and poststructural work, but also to highlight the capacity of Black feminist scholarship to unpick and destabilise the known and (...) knowable in ways that are profoundly ontological, and which offer potential routes to meaningful social change through the hard task of working across difference. The three books reviewed here by Shirley Anne Tate, Suryia Nayak and Shona Hunter are theoretically rich and complex in breadth, scope and range, drawing on extensive Black feminist scholarship, as well as critical race, critical feminist, psychosocial, psychoanalytic, postcolonial, decolonial and poststructural approaches. Each book is embedded in everyday practices and social processes, offering multi-layered movement across different spatial-social and affective scales in ways that allow ‘big’ insights to emerge from the locatedness and particularity of human experience. They are reviewed in turn and some concluding comments identify important commonalities across the texts. (shrink)

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)
