The aim of this study was to examine preliminary evidence of the validity of the Trauma Reflective Functioning Scale and to investigate reflective functioning and attachment in pregnant women with histories of trauma, with a particular focus on the capacity to mentalize regarding trauma and its implications for adaptation to pregnancy and couple functioning. The Adult Attachment Interview was used to assess attachment, unresolved trauma and mentalization (measured as reflective function; RF) regarding relationships with attachment figures (RF-G) and trauma (RF-T) (...) in 100 pregnant women with histories of abuse and neglect. The majority (63%) of women had insecure attachment states of mind and approximately half were unresolved regarding trauma. Furthermore, the majority of women manifested deficits specific to RF-T. Their RF-T was significantly lower than their RF-G; the findings indicate that women with histories of childhood abuse and neglect do not manifest a generic inhibition of reflectiveness, but a collapse of mentalization specific to trauma. Low RF-T, indicative of difficulty in considering traumatic experiences in mental state terms, was associated with difficulty in investment in the pregnancy and lack of positive feelings about the baby and motherhood. In addition, low RF-T was also associated with difficulties in intimate relationships. Results of a regression analysis with RF indicated that RF-T was the best predictor of investment in pregnancy and couple functioning. In sum, the study provides preliminary evidence that RF-T can be reliably measured and is a valid construct that has potential usefulness for research and clinical practice. It highlights the importance of mentalization specifically about trauma and suggests that it is not the experience of trauma per se, but the absence of mentalization regarding trauma that is associated with difficulties in close relationships and in making the transition to parenthood.

This paper presents some impossibility results for certain views about what you should do when you are uncertain about which moral theory is true. I show that under reasonable and extremely minimal ways of defining what a moral theory is, it follows that the concept of expected moral choiceworthiness is undefined, and more generally that any theory of decision-making under moral uncertainty must generate pathological results.

Republican and so-called independence conceptions of freedom stand out from other conceptions by embedding strong modal conditions on what it takes for a person to count as being free to do something. For this reason, the extent of one’s freedom, conceived under republican/independentist lights, cannot be measured by any of the measures of freedom that have been developed so far in the literature on freedom, since these do not register the requisite modal constraints. In this paper I propose a measure (...) of freedom that does capture the requisite modal concerns. I do so by relying on work in the semantics of counterfactuals to define a measure of how modally robustly available an option is to an individual. (shrink)

It is usual to identify initial conditions of classical dynamical systems with mathematical real numbers. However, almost all real numbers contain an infinite amount of information. I argue that a finite volume of space can’t contain more than a finite amount of information, hence that the mathematical real numbers are not physically relevant. Moreover, a better terminology for the so-called real numbers is “random numbers”, as their series of bits are truly random. I propose an alternative classical mechanics, which is (...) empirically equivalent to classical mechanics, but uses only finite-information numbers. This alternative classical mechanics is non-deterministic, despite the use of deterministic equations, in a way similar to quantum theory. Interestingly, both alternative classical mechanics and quantum theories can be supplemented by additional variables in such a way that the supplemented theory is deterministic. Most physicists straightforwardly supplement classical theory with real numbers to which they attribute physical existence, while most physicists reject Bohmian mechanics as supplemented quantum theory, arguing that Bohmian positions have no physical reality.

Most physics theories are deterministic, with the notable exception of quantum mechanics which, however, comes plagued by the so-called measurement problem. This state of affairs might well be due to the inability of standard mathematics to “speak” of indeterminism, its inability to present us a worldview in which new information is created as time passes. In such a case, scientific determinism would only be an illusion due to the timeless mathematical language scientists use. To investigate this possibility it is necessary (...) to develop an alternative mathematical language that is both powerful enough to allow scientists to compute predictions and compatible with indeterminism and the passage of time. We suggest that intuitionistic mathematics provides such a language and we illustrate it in simple terms. (shrink)

Research seeking a scientific foundation for the theory of art appreciation has raised controversies at the intersection of the social and cognitive sciences. Though equally relevant to a scientific inquiry into art appreciation, psychological and historical approaches to art developed independently and lack a common core of theoretical principles. Historicists argue that psychological and brain sciences ignore the fact that artworks are artifacts produced and appreciated in the context of unique historical situations and artistic intentions. After revealing flaws in the (...) psychological approach, we introduce a psycho-historical framework for the science of art appreciation. This framework demonstrates that a science of art appreciation must investigate how appreciators process causal and historical information to classify and explain their psychological responses to art. Expanding on research about the cognition of artifacts, we identify three modes of appreciation: basic exposure to an artwork, the artistic design stance, and artistic understanding. The artistic design stance, a requisite for artistic understanding, is an attitude whereby appreciators develop their sensitivity to art-historical contexts by means of inquiries into the making, authorship, and functions of artworks. We defend and illustrate the psycho-historical framework with an analysis of existing studies on art appreciation in empirical aesthetics. Finally, we argue that the fluency theory of aesthetic pleasure can be amended to meet the requirements of the framework. We conclude that scientists can tackle fundamental questions about the nature and appreciation of art within the psycho-historical framework. (shrink)

The contemporary discussion of modesty has focused on whether or not modest people are accurate about their own good qualities. This essay argues that this way of framing the debate is unhelpful and offers examples to show that neither ignorance nor accuracy about the good qualities related to oneself is necessary for modesty. It then offers an attention-based account, claiming that what is necessary for modesty is to direct one’s attention in certain ways. By analyzing modesty in this way, we (...) can best explain the distinct features of modesty, keep much of what is intuitive in contemporary accounts, and better understand why modesty is a virtue at all.

The growing popularization of stakeholder theory among management scholars has offered a useful framework for understanding the multiple and interdependent roles of government and business in an increasingly challenging political and regulatory environment. Despite this trend, attention to the role and responsibility of government to protect citizen rights has been limited. To the two traditional stakeholder theory views of government where the focal organization remains the firm, we propose to add two views by pivoting the government’s place and making it (...) the focal organization. We thus describe governments as serving four roles in the business–government–society nexus. For each role, we analyze typical governmental activities/behaviors, relationships with firms’ stakeholders, as well as the challenges and limits to these roles. We also focus on the central notion of salience amplification, as a means of checks and balances across stakeholders in order to safeguard citizen rights and reveal the greater good. (shrink)

This paper challenges a widespread, if tacit, assumption of animal ethics, namely, that the only properties of entities that matter to their moral status are intrinsic, cross‐specific properties—typically psychological capacities. According to moral individualism (Rachels 1990; McMahan 2002; 2005), the moral status of an individual, and how to treat him or her, should only be a function of his or her individual properties. I focus on the fundamental assumption of moral individualism, which I call intrinsicalism. On the challenged view, pigs, (...) puppies and babies, insofar as they are intrinsically similar in morally relevant respects are equally deserving of having their interests satisfied (Norcross 2004). Moreover, relationships—merely agent-relative—are assumed to be irrelevant to moral status. I argue that, while some intrinsic properties are indeed fundamentally relevant, the principled exclusion of extrinsic properties (in virtue of extrinsicness) is unwarranted. From uncontroversial assumptions about supervenience, final value, and moral status, I argue for the relevance of extrinsic properties to moral status based on vulnerability and “reasonable partiality”, as illustrated by pet-keeping.

In order to describe the logic of morality, "contractualist" philosophers have studied how individuals behave when they choose to follow their moral intuitions. These individuals, contractualists note, often act as if they have bargained and thus reached an agreement with others about how to distribute the benefits and burdens of mutual cooperation. Using this observation, such philosophers argue that the purpose of morality is to maximize the benefits of human interaction. The resulting "contract" analogy is both insightful and puzzling. On (...) one hand, it captures the pattern of moral intuitions, thus answering questions about human cooperation: why do humans cooperate? Why should the distribution of benefits be proportionate to each person's contribution? Why should the punishment be proportionate to the crime? Why should the rights be proportionate to the duties? On the other hand, the analogy provides a mere as-if explanation for human cooperation, saying that cooperation is "as if" people have passed a contract-but since they didn't, why should it be so? To evolutionary thinkers, the puzzle of the missing contract is immediately reminiscent of the puzzle of the missing "designer" of life-forms, a puzzle that Darwin's theory of natural selection essentially resolved. Evolutionary and contractualist theory originally intersected at the work of philosophers John Rawls and David Gauthier, who argued that moral judgments are based on a sense of fairness that has been naturally selected. In this book, Nicolas Baumard further explores the theory that morality was originally an adaptation to the biological market of cooperation, an arena in which individuals competed to be selected for cooperative interactions. In this environment, Baumard suggests, the best strategy was to treat others with impartiality and to share the costs and benefits of cooperation in a fair way, so that those who offered less than others were left out of cooperation while those who offered more were exploited by their partners. It is with this evolutionary approach that Baumard ultimately accounts for the specific structure of human morality. (shrink)

A growing literature argues that animals can act for moral reasons without being responsible. I argue that the literature often fails to maintain a clear distinction between moral behavior and moral agency, and I formulate a dilemma: either animals are less moral or they are more responsible than the literature suggests. If animals can respond to moral reasons, they are responsible according to an influential view of moral responsibility—Quality of Will. But if they are responsible, as some argue, costly implications (...) must be acknowledged. If, however, they should not be considered responsible, then we may have to reassess the meaning of animal morality. I discuss ways to eschew responsibility or to tailor it to animals and argue that each requires a revised conception of animal morality. (shrink)

How might a human communication system be bootstrapped in the absence of conventional language? We argue that motivated signs play an important role (i.e., signs that are linked to meaning by structural resemblance or by natural association). An experimental study is then reported in which participants try to communicate a range of pre-specified items to a partner using repeated non-linguistic vocalization, repeated gesture, or repeated non-linguistic vocalization plus gesture (but without using their existing language system). Gesture proved more effective (measured (...) by communication success) and more efficient (measured by the time taken to communicate) than non-linguistic vocalization across a range of item categories (emotion, object, and action). Combining gesture and vocalization did not improve performance beyond gesture alone. We experimentally demonstrate that gesture is a more effective means of bootstrapping a human communication system. We argue that gesture outperforms non-linguistic vocalization because it lends itself more naturally to the production of motivated signs. (shrink)

This study investigates the social–psychological mechanisms leading individuals in organizations to engage in environmental citizenship behaviors, which entail keeping abreast of, and participating in, the environmental affairs of a company. Informed by the corporate greening and organizational behavior literature, we suggested that an employee’s level of involvement in the management of a company’s environmental impact was the overt manifestation of his or her discretionary sense of commitment to environmental concerns in the work context, and that such commitment developed through the (...) interplay of individual, organizational, and supervisory factors. Our general findings support the idea that when environmental protection is valued and encouraged by the company and line managers, organization members are more likely to experience a volitional sense of attachment and responsibility to corporate environmental goals and values, which is enacted through citizenship behaviors. We also expected that individual ecological beliefs would strengthen the environmental commitment of employees via identification with, and adherence to, the socially responsible cause embodied by the organization and its managerial staff. But it did not. On the contrary, the data indicated that corporate environmental policy is more likely to influence an employee’s level of environmental commitment when he or she holds weak versus strong personal ecological beliefs. Theoretical and managerial implications of our findings are discussed. (shrink)

Discussions on indeterminism in physics focus on the possibility of an open future, i.e. the possibility of having potential alternative future events, the realisation of one of which is not fully determined by the present state of affairs. Yet, can indeterminism affect also the past, making it open as well? We show that by upholding principles of finiteness of information one can entail such a possibility. We provide a toy model that shows how the past could be fundamentally indeterminate, while (...) also explaining the intuitive (and observed) asymmetry between the past—which can be remembered, at least partially—and the future—which is impossible to fully predict.

What has become generally known as the Berlin School of Logical Empiricism constitutes a philosophical movement that was erected on foundations laid by Albert Einstein. His revolutionary work in physics had a profound impact on philosophers interested in scientific issues, prominent among them Paul Oppenheim and Hans Reichenbach, the founding fathers of the school, who joined in viewing him as their hero among philosopher-scientists. Overall the membership of this school falls into three groups. The founding generation was linked by the (...) circumstance that both Grelling and Reichenbach were collaborators of Oppenheim; the middle generation by the fact that both Hempel and Helmer were students of Reichenbach's in Berlin; and the younger generation by the fact that all of its members were students and disciples either of Reichenbach's or of Hempel's in the USA. Three stages are at issue: an initial phase in Berlin, a transatlantic migration, and a continuation in the U.S.A.--principally in Pittsburgh. (shrink)

Urban animals can benefit from living in cities, but this also makes them vulnerable as they increasingly depend on the advantages of urban life. This article has two aims. First, I provide a detailed analysis of the concept of captivity and explain why it matters to nonhuman animals—because and insofar as many of them have a (non-substitutable) interest in freedom. Second, I defend a surprising implication of the account—pushing the boundaries of the concept while the boundaries of cities and human (...) activities expand. I argue for the existence of the neglected problem of pervasive captivity, of which urban wildlife is an illustration. Many urban animals are confined, controlled and dependent, therefore often captive of expanding urban areas. While I argue that captivity per se is value-neutral, I draw the ethical and policy implications of harmful pervasive captivity. (shrink)

Syllogisms (e.g. “All A are B; All B are C; What is true about A and C?”) are a long‐studied area of human reasoning. Riesterer, Brand, and Ragni compare a variety of models to human performance and show that not only do current models have a lot of room for improvement, but more importantly a large part of this improvement must come from examining individual differences in performance.

Effective altruism (EA) requires that when we donate to charity, we maximize the beneficial impact of our donations. While we are in broad sympathy with EA, we raise a practical problem for EA, which is that there is a crucial empirical presupposition implicit in its charity assessment methods which is false in many contexts. This is the presupposition that the magnitude of the benefits (or harms) generated by some charity vary continuously in the scale of the intervention performed. We characterize (...) a wide class of cases where this assumption fails, and then draw out the normative implications of this fact. (shrink)

This article provides a philosophical response to the need for truth-telling about colonial history, focussing on the Australian context. The response consists in inviting philosophers and the public to engage in social-justice practices specified by a model called Distributed Truth-Telling (DTT), which integrates the historiography of injustices affecting Indigenous peoples with insights from social philosophy and cultural evolution theory. By contrast to official and large-scale truth commissions, distributed truth-telling is a set of non-elitist practices that weave three components: first, multisite, (...) multiformat, and multiscale inquiries into injustices; second, remedial imaginings and reasoning about moral repair and reconciliated futures; and finally, emotions suitable for motivating agents to cooperatively plan and implement moral revolutions. Distributed truth-telling can entrench virtuous feedback loops that contribute to moral revolutions. However, vicious feedback loops associated with collective denial and biases can impair distributed truth- telling and thwart moral revolutions. (shrink)

This book is the first extensive treatment of Husserl's phenomenology of time-consciousness. Nicolas de Warren uses detailed analysis of texts by Husserl, some only recently published in German, to examine Husserl's treatment of time-consciousness and its significance for his conception of subjectivity. He traces the development of Husserl's thinking on the problem of time from Franz Brentano's descriptive psychology, and situates it in the framework of his transcendental project as a whole. Particular discussions include the significance of time-consciousness for (...) other phenomenological themes: perceptual experience, the imagination, remembrance, self-consciousness, embodiment, and the consciousness of others. The result is an illuminating exploration of how and why Husserl considered the question of time-consciousness to be the most difficult, yet also the most central, of all the challenges facing his unique philosophical enterprise"--Provided by publisher.

Commentary on Neuhaus and Parent, 'Gene doping--In Animals?' (2019).

This article discusses conceptions of modesty and humility and their key features. It gives a brief historical overview of debates about whether or not they’re really virtues at all. It also discusses theories of modesty and humility that root them in the presence or absence of particular beliefs, emotions, desires, and attention. it also discusses related phenomena in epistemology: rational limits on self-ascription of error, attitudes to disagreement, and openness to alternative views.

This article aims at understanding how "ethical public issues" are created, and dealt within a public arena. Here, we view ethical public issues as social constructs, which are the results of issue framing contests. Such an approach will enable us to understand how ethical public issues emerge and are shaped by strategizing actors (including firms, NGOs, the media, and governments), in an attempt to impose their own definition and preferred solution to the issue. We also propose key factors which explain (...) the success of a framing attempt, and evidence of such success. The empirical case of the labor conditions in West Africa's cocoa industry is used to illustrate this theoretical framework and methodological approach. (shrink)

The prefrontal cortex is widely believed to play an important role in facilitating people's ability to switch performance between different tasks. We present a biologically‐based computational model of prefrontal cortex (PFC) that explains its role in task switching in terms of the greater flexibility conferred by activation‐based working memory representations in PFC, as compared with more slowly adapting weight‐based memory mechanisms. Specifically we show that PFC representations can be rapidly updated when a task switches via a dynamic gating mechanism based (...) on a temporal‐differences reward‐prediction learning mechanism. Unlike prior models of this type, the present model develops all of its internal representations via learning mechanisms as shaped by the demands of continuous periodic task switching. This advance opens up a new domain of research into the interactions between working memory task demands and the representations that develop to meet them. Results on a version of the Wisconsin card sorting task are presented for the full model and a number of comparison networks that test the importance of various model features. Furthermore, we show that a lesioned model produces perseverative errors like those seen in frontal patients. (shrink)

We present a new proof of soundness/completeness of tableaux with respect to dialogical games in Classical First-Order Logic. As far as we know it is the first thorough result for dialogical games where finiteness of plays is guaranteed by means of what we call repetition ranks.

It is commonly assumed that moral deliberation requires that the alternatives available in a choice situation are evaluatively comparable. This comparability assumption is threatened by claims of incomparability, which is often established by means of the small improvement argument (SIA). In this paper I argue that SIA does not establish incomparability in a stricter sense. The reason is that it fails to distinguish incomparability from a kind of evaluative indeterminacy which may arise due to the vagueness of the evaluative comparatives (...) ‘better than,’ ‘worse than,’ and ‘equally as good as.’.

This paper aims to draw attention to an important but underappreciated aspect of the instrumental value of freedom: its diagnostic value. This is the value freedom has insofar as it makes it possible for us to discover ourselves and improve ourselves in our capacity to make value judgements. Diagnostic value, I argue, has an important role to play in explaining the value we attach to freedom. Accordingly, this paper is aimed at elucidating this concept, examining its relevance to our lives, (...) and defending an account of how to measure the diagnostic value of opportunities and sets of opportunities.

Sex‐determining factors are usually assumed to be either genetic or environmental. The present paper aims at drawing attention to the potential contribution of developmental noise, an important but often‐neglected component of phenotypic variance. Mutual inhibitions between male and female pathways make sex a bistable equilibrium, such that random fluctuations in the expression of genes at the top of the cascade are sufficient to drive individual development toward one or the other stable state. Evolutionary modeling shows that stochastic sex determinants should (...) resist elimination by genetic or environmental sex determinants under ecologically meaningful settings. On the empirical side, many sex‐determination systems traditionally considered as environmental or polygenic actually provide evidence for large components of stochasticity. In reviewing the field, I argue that sex‐determination systems should be considered within a three‐ends continuum, rather than the classical two‐ends continuum. (shrink)

How do humans manage to keep track of a gradually changing object or person as the same persisting individual despite the fact that the extraction of information about this individual must often rely on heterogeneous information sources and heterogeneous tracking methods? The article introduces the Empirical Tracking of Individuals theory to address this problem. This theory proposes an analysis of the concept of integrated tracking, which refers to the capacity to acquire, store, and update information about the identity and location (...) of individuals in our environment. It hypothesizes that certain functions of attention are a key to explaining how the cognitive flexibility of the human mind overcomes the heterogeneity of sources and methods in integrated tracking. At least two premises lend support to this hypothesis. First, heterogeneity of tracking sources is overcome by the combination of information from multiple perceptual modalities and a phenomenon of multisensory 'transparency'. Second, heterogeneity of tracking sources and methods may also be overcome by inferences that combine information across domains to acquire reasons to believe propositions about the target's location and identity.

In a 1993 paper, I argued that empirical treatments of the epistemologyused by scientists in experimental work are too abstract in practice tocounter relativist efforts to explain the outcome of scientificcontroversies by reference to sociological forces. This was because, atthe rarefied level at which the methodology of scientists is treated byphilosophers, multiple mutually inconsistent instantiations of theprinciples described by philosophers are employed by contestingscientists. These multiple construals change within a scientificcommunity over short time frames, and these different versions ofscientific methodology (...) can determine the outcome of a controversy. Iillustrated with a comparatively detailed analysis of the methodologyused by biologists debating the existence of an entity called thebacterial mesosome between the mid-1950s and the mid-1970s. This 1993piece has drawn several critiques in the philosophical literature. Inthis present piece I respond to these critiques and argue that they failto address the core argument of the original paper, and I reflectfurther on the methodologies of philosophers of science pursuingempirical or `naturalistic' epistemology.

After 100+ years of studying syllogistic reasoning, what have we learned? Well, Riesterer and colleagues suggest that we have learned to throw away most of the data! If that seems like a bad idea to you then, be assured, that the authors agree with you.

Riesterer and colleagues (...) introduce heuristic rules for predicting NVC and provide directions to modelers on how to up their game. (shrink)

The so-called “Fragment on Machines” of Marx has become in recent decades one of his most revisited texts. This has undoubtedly occurred under the influence of the reading carried out by the school of thought known as Italian autonomism, for whom this text would anticipate the stage of capitalism that opens after the crisis of the 1970s. The “Fragment” would theoretically articulate this stage in terms of a “crisis of value measurement” that would result from the impossibility of framing the (...) new form acquired by labor in “postfordism” into the social norm of working time. The fundamental task of this article is to discuss this interpretative key of the “Fragment” and conceptually articulate its central elements in order to undertake an alternative reading of it, which would also have the potential to critically analyze current capitalism.

Las transformaciones acaecidas en el sistema productivo aproximadamente desde principios de la década de 1970 vienen generado una serie de discusiones y posicionamientos teóricos respecto del lugar del trabajo en las sociedades contemporáneas. Habermas y Gorz son dos de los pensadores que en este contexto han sostenido que las sociedades desarrolladas transitan un modelo en el cual inevitablemente el tiempo de trabajo necesario disminuye, tornándose estructurales la desocupación y precarización laborales. Sin embargo, esto será visto como una oportunidad, pues estos (...) autores entienden que el trabajo habría dejado de ser hace tiempo el lugar en el que los individuos podrían realizarse personal y vitalmente, incluso superado el capitalismo. El desafío radicaría entonces en pensar alternativas ante la crisis de la llamada “sociedad del trabajo”. No obstante, los discursos contemporáneos de gestión empresarial parecen colocar un signo de interrogación a dichos análisis al pregonar el involucramiento activo —personal y afectivo— de los sujetos en los procesos productivos. Lo cual estaría dando lugar a la siguiente paradoja: lo que aquellos autores entendían que sólo podía florecer allende los espacios productivos es precisamente lo que la gestión contemporánea del trabajo demanda en primer lugar, y ello en miras de mejorar la productividad e incrementar las ganancias de las empresas. El objetivo de este artículo es exponer con detalle y rigor conceptual esta paradoja, desde el horizonte ético-epistemológico de una teoría crítica que pueda estudiar el presente detectando tanto sus fisuras como sus posibilidades inmanentes de transformación social y política.

The theoretical literature on vertical relationships usually assumes that beliefs about secret contracts take specific forms. In a recent paper, Eguia et al. (Games Econ Behav 109:465–483,2018) propose a new selection criterion that does not impose any restriction on beliefs. In this article, we extend their criterion by generalizing it to risk-averse retailers, and we show that risk aversion modifies the size of the belief subsets that support each equilibrium. We conduct an experiment which revisits that of Eguia et al. (...) (Games Econ Behav 109:465–483,2018). We design a new treatment effect on equilibrium selection depending on the retailers’ risk sensitivity. Experimental results confirm the treatment effect: the more sensitivity there is towards risk, the more the equilibrium played is consistent with passive beliefs. In addition, extending Eguia et al.’s (Games Econ Behav 109:465–483,2018) criterion to risk-averse retailers improves its predictive power on the equilibria played, especially for a population of retailers with moderate to extreme risk aversion.
