Resumen La argumentación es una forma de discurso en la que un hablante defiende una postura en una discusión. El presente trabajo se enfoca en la complejidad argumentativa y los recursos evaluativos y evidenciales que caracterizan las disputas de niños de diverso nivel socioeconómico. Se analizaron 94 disputas entre niños de 4 años y otros niños (5 a 10 años) en situaciones de juego espontáneo registradas en hogares de sectores socioeconómicos medio y bajo. El análisis identificó diferencias marginales en la (...) complejidad argumentativa entre los grupos. Por su parte se hallaron diferencias significativas en recursos de evaluativos de emocionalidad y en los evidenciales deónticos y exclamativos a favor de los sectores de nivel socioeconómico bajo. Los sectores medios registraron un mayor empleo de expresiones de causalidad y conectores. Los resultados se discuten a la luz de los hallazgos de investigaciones previas. Abstract Argumentation is a type of discourse in which a speaker defends a claim in a discussion. The present work focuses on the argumentative complexity and the evaluative and evidential resources that characterize the disputes of children of different socioeconomic levels. We analyzed 94 disputes between 4-year-old children and other children (5 to 10 years old) in situations of spontaneous play registered in homes of middle and low socioeconomic status (SES). The analysis identified marginal differences in argumentative complexity between the groups. On the other hand, significant differences were found in evaluative expressions of emotion and in deontic and exclamatory evidential markers, more frequently used by the low SES group. The mid SES group tends to use a higher number of expressions of causality and connectors. The results are discussed with reference to the findings of previous research. (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.

The empirical study of belief is emerging at a rapid clip, uniting work from all corners of cognitive science. Reliance on belief in understanding and predicting behavior is widespread. Examples can be found, inter alia, in the placebo, attribution theory, theory of mind, and comparative psychological literatures. Research on belief also provides evidence for robust generalizations, including about how we fix, store, and change our beliefs. Evidence supports the existence of a Spinozan system of belief fixation: one that is automatic (...) and independent of belief rejection. Independent research supports the existence of a system of fragmented belief storage: one that relies on large numbers of causally isolated, context-sensitive stores of belief in memory. Finally, empirical and observational data support at least two systems of belief change. One system adheres, mostly, to epistemological norms of updating; the other, the psychological immune system, functions to guard our most centrally held beliefs from potential inconsistency with newly formed beliefs. Refining our under- standing of these systems can shed light on pressing real-world issues, such as how fake news, propaganda, and brainwashing exploit our psychology of belief, and how best to construct our modern informational world.

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)

This monograph proposes a new way of implementing interaction in logic. It also provides an elementary introduction to Constructive Type Theory. The authors equally emphasize basic ideas and finer technical details. In addition, many worked out exercises and examples will help readers to better understand the concepts under discussion. One of the chief ideas animating this study is that the dialogical understanding of definitional equality and its execution provide both a simple and a direct way of implementing the CTT approach (...) within a game-theoretical conception of meaning. In addition, the importance of the play level over the strategy level is stressed, binding together the matter of execution with that of equality and the finitary perspective on games constituting meaning. According to this perspective the emergence of concepts are not only games of giving and asking for reasons, they are also games that include moves establishing how it is that the reasons brought forward accomplish their explicative task. Thus, immanent reasoning games are dialogical games of Why and How. (shrink)

This article argues for a novel approach to the measurement of freedom of choice, on which the availability of an option is a matter of degree, rather than a bivalent matter of being either available or not. This approach is motivated by case studies involving weakness of will, where deficiencies in willpower seem to impair individual freedom by making certain alternatives much harder to pursue. This approach is perfectly general, however: its graded analysis of option availability can be extended to (...) cases where weakness of will is not involved and can be used to generalize numerous existing measures of freedom.

Many of us, even on our happiest days, struggle to quiet the constant buzz of anxiety in the background of our minds. All kinds of worries--worries about losing people and things, worries about how we seem to others--keep us from peace of mind. Distracted or misled by our preoccupations, misconceptions, and, most of all, our obsession with ourselves, we don't see the world clearly--we don't see the world as it really is. In our search for happiness and the good life, (...) this is the main problem. But luckily there is a solution, and on the path to understanding it, we can make use of the rich and varied teachings that have developed over centuries of Buddhist thought. With clarity and compassion, Nicolas Bommarito explores the central elements of centuries of Buddhist philosophy and practice, explaining how they can improve your life and teach you to live without fear. Mining important texts and lessons for practical guidance, he provides a friendly guide to the very practical goals that underpin Buddhist philosophy. After laying out the basic ideas, Bommarito walks readers through a wide range of techniques and practices we can adopt to mend ingrained habits. Rare for its exploration of both the philosophy that motivates Buddhism and its practical applications, this is a compassionate guide to leading a good life that anyone can follow. (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.

This essay defends the possibility of preemptive forgiving, that is, forgiving before the offending action has taken place. This essay argues that our moral practices and emotions admit such a possibility, and it attempts to offer examples to illustrate this phenomenon. There are two main reasons why someone might doubt the possibility of preemptive forgiving. First, one might think that preemptive forgiving would amount to granting permission. Second, one might think that forgiving requires emotional content that is not available prior (...) to wrongdoing. If, however, preemptively forgiving is genuinely possible—as this essay hopes to illustrate—then this fact has implications for our understanding of both relational normativity and the nature of forgiveness.

Since the Industrial Revolution, human societies have experienced high and sustained rates of economic growth. Recent explanations of this sudden and massive change in economic history have held that modern growth results from an acceleration of innovation. But it is unclear why the rate of innovation drastically accelerated in England in the eighteenth century. An important factor might be the alteration of individual preferences with regard to innovation resulting from the unprecedented living standards of the English during that period, for (...) two reasons. First, recent developments in economic history challenge the standard Malthusian view according to which living standards were stagnant until the Industrial Revolution. Pre-industrial England enjoyed a level of affluence that was unprecedented in history. Second, behavioral sciences have demonstrated that the human brain is designed to respond adaptively to variations in resources in the local environment. In particular, Life History Theory, a branch of evolutionary biology, suggests that a more favorable environment should trigger the expression of future-oriented preferences. In this paper, I argue that some of these psychological traits – a lower level of time discounting, a higher level of optimism, decreased materialistic orientation, and a higher level of trust in others – are likely to increase the rate of innovation. I review the evidence regarding the impact of affluence on preferences in contemporary as well as past populations, and conclude that the impact of affluence on neurocognitive systems may partly explain the modern acceleration of technological innovations and the associated economic growth.

Sometimes physicians lie to third-party payers in order to grant their patients treatment they would otherwise not receive. This strategy, commonly known as gaming the system, is generally condemned for three reasons. First, it may hurt the patient for the sake of whom gaming was intended. Second, it may hurt other patients. Third, it offends contractual and distributive justice. Hence, gaming is considered to be immoral behavior. This article is an attempt to show that, on the contrary, gaming may sometimes (...) be a physician's duty. Under specific circumstances, gaming may be necessary from the viewpoint of the internal morality of medicine. Moreover, the objections against gaming are examples of what we call the idealistic fallacy, that is, the fallacy of passing judgments in a nonideal world according to ideal standards. Hence, the objections are inconclusive. Gaming is sometimes justified, and may even be required in the name of beneficence. (shrink)

This longitudinal study investigated the capability of various positive psychological resources to directly or indirectly protect specific well-being outcomes and moderate the effects on well-being of health and economic threats in a lockdown situation during the 2020 health crisis in France. At the beginning of lockdown, participants completed self-assessment questionnaires to document their initial level of well-being and state of nine different well-established psychological resources, measured as traits: optimism, hope, self-efficacy, gratitude toward the world, self-transcendence, wisdom, gratitude of being, peaceful (...) disengagement, and acceptance. Three weeks later, a weekly follow-up was started to record changes in well-being and reported threats for a duration of 5 weeks. Results show that psychological resources efficiently protected well-being in a variety of ways: they buffered the adverse effects of reported threats to health and wealth, increased the well-being averages, and reduced the decline in well-being over time. More specifically, emotional well-being was positively predicted by hope, gratitude of being, and, to a lesser level, by acceptance; psychological well-being by self-efficacy, personal wisdom, and gratitude of being; social well-being only by gratitude toward the world; and inner well-being by optimism, gratitude of being, and acceptance. The study emphasizes the importance of cultivating psychological resources in ordinary times to protect individuals' well-being when difficult and extraordinary circumstances occur. It also offers clues to the kind of resources one may want to develop. (shrink)

This book features 20 essays that explore how Latin medieval philosophers and theologians from Anselm to Buridan conceived of habitus, as well as detailed studies of the use of the concept by Augustine and of the reception of the medieval doctrines of habitus in Suàrez and Descartes. Habitus are defined as stable dispositions to act or think in a certain way. This definition was passed down to the medieval thinkers from Aristotle and, to a lesser extent, Augustine, and played a (...) key role in many of the philosophical and theological developments of the time. Written by leading experts in medieval and modern philosophy, the book offers a historical overview that examines the topic in light of recent advances in medieval cognitive psychology and medieval moral theory. Coverage includes such topics as the metaphysics of the soul, the definition of virtue and vice, and the epistemology of self-knowledge. The book also contains an introduction that is the first attempt at a comprehensive survey of the nature and function of habitus in medieval thought. The material will appeal to a wide audience of historians of philosophy and contemporary philosophers. It is relevant as much to the historian of ancient philosophy who wants to track the historical reception of Aristotelian ideas as it is to historians of modern philosophy who would like to study the progressive disappearance of the term “habitus” in the early modern period and the concepts that were substituted for it. In addition, the volume will also be of interest to contemporary philosophers open to historical perspectives in order to renew current trends in cognitive psychology, virtue epistemology, and virtue ethics.

Do scientific theories limit human knowledge? In other words, are there physical variables hidden by essence forever? We argue for negative answers and illustrate our point on chaotic classical dynamical systems. We emphasize parallels with quantum theory and conclude that the common real numbers are, de facto, the hidden variables of classical physics. Consequently, real numbers should not be considered as ``physically real" and classical mechanics, like quantum physics, is indeterministic.

Recent models of the conceptual system hold that concepts are grounded in simulations of actual experiences with instances of those concepts in sensory-motor systems (e.g., Barsalou, 1999, 2003; Solomon & Barsalou, 2001). Studies supportive of such a viewhave shown that verifying a property of a concept in one modality, and then switching to verify a property of a different concept in a different modality generates temporal processing costs similar to the cost of switching modalities in perception. In addition to non-emotional (...) concepts, the present experiment investigated switching costs in verifying properties of positive and negative (emotional) concepts. Properties of emotional concepts were taken from vision, audition, and the affective system. Parallel to switching costs in neutral concepts, the study showed that for positive and negative concepts, verifying properties from different modalities produced processing costs such that reaction times were longer and error rates were higher. Importantly, this effect was observed when switching from the affective system to sensory modalities, and vice-versa. These results support the embodied cognition view of emotion in humans. (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.

I defend an account of when and why anger is morally virtuous or vicious. Anger often manifests what we care about; a sports fan gets angry when her favorite team loses because she cares about the team doing well. Anger, I argue, is made morally virtuous or vicious by the underlying care or concern. Anger is virtuous when it manifests moral concern and vicious when it manifests moral indifference or ill will. In defending this view, I reject two common views (...) about anger and moral character. First, I respond to several arguments that attempt to show that all anger is vicious. Then I respond to the view that some anger is required to be a virtuous person. Anger, on my view, can be morally virtuous but is not a necessary condition for being a virtuous person. This best accommodates not only morally irrelevant failures to get angry but also allows for emotional variation among virtuous people. (shrink)

This article offers a justification for accommodating claims of conscience. The standard justification points to the pain that acting against one’s conscience entails. But that defense cannot make sense of the state’s refusal to accommodate individuals where the law interferes with their deeply meaningful but nonmoral projects. An alternative justification, we argue, arises once one recognizes the connection between conscience and moral address: One’s lived moral convictions determine when and with what force one can hold others to account. Acting against (...) one’s convictions can undermine one’s standing to blame others who act in similar ways. When the state compels someone to act against conscience, it renders her complicit in conduct she takes to be wrong and thereby impairs her ability to condemn similar conduct in the future, in a manner akin to the hypocrite. The reason the state should not compel people to act against conscience, then, is that doing so would undercut their moral standing. (shrink)

Artificial intelligence and robots may progressively take a more and more prominent place in our daily environment. Interestingly, in the study of how humans perceive these artificial entities, science has mainly taken an anthropocentric perspective (i.e., how distant from humans are these agents). Considering people’s fears and expectations from robots and artificial intelligence, they tend to be simultaneously afraid and allured to them, much as they would be to the conceptualisations related to the divine entities (e.g., gods). In two experiments, (...) we investigated the proximity of representation between artificial entities (i.e., artificial intelligence and robots), divine entities and natural entities (i.e., humans and other animals) at both an explicit (Study 1) and an implicit level (Study 2). In the first study, participants evaluated these entities explicitly on positive and negative attitudes. Hierarchical clustering analysis showed that participants’ representation of artificial intelligence, robots and divine entities were similar, while the representation of humans tended to be associated with that of animals. In the second study, participants carried out a word/non-word decision task including religious semantic-related words and neutral words after the presentation of a masked prime referring to divine entities, artificial entities and natural entities (or a control prime). Results showed that after divine and artificial entity primes, participants were faster to identify religious words as words compared to neutral words arguing for a semantic activation. We conclude that people make sense of the new entities by relying on already familiar entities and in the case of artificial intelligence and robots, people appear to draw parallels to divine entities.

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. The sad fact is that the conclusion of “No Valid Conclusion” (NVC) is one of the most frequently selected responses in syllogistic reasoning but these “majority data” have been ignored by most researchers. Riesterer and colleagues (...) introduce heuristic rules for predicting NVC and provide directions to modelers on how to up their game. (shrink)

In the literature on medical ethics, it is generally admitted that vulnerable persons or groups deserve special attention, care or protection. One can define vulnerable persons as those having a greater likelihood of being wronged – that is, of being denied adequate satisfaction of certain legitimate claims. The conjunction of these two points entails what we call the Special Protection Thesis. It asserts that persons with a greater likelihood of being denied adequate satisfaction of their legitimate claims deserve special attention, (...) care or protection. Such a thesis remains vague, however, as long as we do not know what legitimate claims are. This article aims at dispelling this vagueness by exploring what claims we have in relation to health care – thus fleshing out a claim-based conception of vulnerability. We argue that the Special Protection Thesis must be enriched as follows: If individual or group X has a greater likelihood of being denied adequate satisfaction of some of their legitimate claims to physical integrity, autonomy, freedom, social provision, impartial quality of government, social bases of self-respect or communal belonging, then X deserves special attention, care or protection. With this improved understanding of vulnerability, vulnerability talk in healthcare ethics can escape vagueness and serve as an adequate basis for practice. (shrink)

Is suffering really bad? The late Derek Parfit argued that we all have reasons to want to avoid future agony and that suffering is in itself bad both for the one who suffers and impersonally. Nietzsche denied that suffering was intrinsically bad and that its value could even be impersonal. This paper has two aims. It argues against what I call ‘Realism about the Value of Suffering’ by drawing from a broadly Nietzschean debunking of our evaluative attitudes, showing that a (...) recently influential response to the debunking challenge (the appeal to phenomenal introspection) fails. It also argues that a Nietzschean approach is well suited to support the challenge and is bolstered by the empirical literature. As strangers to ourselves, we cannot know whether suffering is really intrinsically bad for us. (shrink)

In Study 1, we examined the moderating impact of alexithymia (i.e., a difficulty identifying and describing feelings to other people and an externally oriented cognitive style) on the automatic processing of affective information. The affective priming paradigm was used, and lower priming effects for high alexithymia scorers were observed when congruent (incongruent) pairs involving nonverbal primes (angry face) and verbal target were presented. The results held after controlling for participants' negative affectivity. The same effects were replicated in Studies 2 and (...) 3, with trait anxiety and depression entered as additional covariates. In Study 3, no moderating impact of alexithymia was found for verbal-facial pairs suggesting that the results cannot be merely explained in terms of transcoding limitations for high alexithymia scorers. Overall, the present results suggest that alexithymia could be related to a difficulty in processing and automatically using high arousal emotional information to respond to concomittant behavioural demands.

Human cognition and behavior are dominated by symbol use. This paper examines the social learning strategies that give rise to symbolic communication. Experiment 1 contrasts an individual-level account, based on observational learning and cognitive bias, with an inter-individual account, based on social coordinative learning. Participants played a referential communication game in which they tried to communicate a range of recurring meanings to a partner by drawing, but without using their conventional language. Individual-level learning, via observation and cognitive bias, was sufficient (...) to produce signs that became increasingly effective, efficient, and shared over games. However, breaking a referential precedent eliminated these benefits. The most effective, most efficient, and most shared signs arose when participants could directly interact with their partner, indicating that social coordinative learning is important to the creation of shared symbols. Experiment 2 investigated the contribution of two distinct aspects of social interaction: behavior alignment and concurrent partner feedback. Each played a complementary role in the creation of shared symbols: Behavior alignment primarily drove communication effectiveness, and partner feedback primarily drove the efficiency of the evolved signs. In conclusion, inter-individual social coordinative learning is important to the evolution of effective, efficient, and shared symbols. (shrink)

The contention of this paper is that the current ethical debate over embryonic stem cell research is polarised to an extent that is not warranted by the underlying ethical conflict. It is argued that the ethical debate can be rendered more nuanced, and less polarised, by introducing non-binary notions of moral rightness and wrongness. According to the view proposed, embryonic stem cell research—and possibly other controversial activities too—can be considered ‘a little bit right and a little bit wrong’. If this (...) idea were to become widely accepted, the ethical debate would, for conceptual reasons, become less polarised. (shrink)

To become more broadly applicable, positions on AI ethics require perspectives from non-Western regions and cultures such as China and Japan. In this paper, we propose that the addition of the concept of harmony to the discussion on ethical AI would be highly beneficial due to its centrality in East Asian cultures and its applicability to the challenge of designing AI for social good. We first present a synopsis of different definitions of harmony in multiple contexts, such as music and (...) society, which reveals that the concept is, at its core, about well-balanced relationships and appropriate actions which give rise to order, balance, and aesthetically pleasing phenomena. The mediator for these well-balanced relationships isTaktwhich is an ability to act thoughtfully and sensibly according to the specific situation and to put things into proportion and order. We propose that the central challenge of building harmonizing AI is to make intelligent systems tactful and also to design and use them tactfully. For an AI system to become tactful, it needs to be able to have an advanced sensitivity to the specific contexts which it is in and their social and ethical implications and have the capability of approximately inferring the emotional and cognitive states of people with whom it is interacting.

Animals who live in cities must coexist with us. They are, as a result, entitled to the conditions of their flourishing. This article argues that, as the boundaries of cities and urban areas expand, the boundaries of our conception of captivity should expand too. Urbanization can undermine animals’ freedoms, hence their ability to live good lives. I draw the implications of an account of “pervasive captivity” against the background of the Capabilities Approach. I construe captivity, including that of urban animals, (...) as affecting a range of animal capabilities, understood as freedoms, and I address some tensions within Nussbaum’s treatment of human-animal conflicts. Using the Capabilities Approach as a guide, I will attempt to motivate a convergence between habitat preservation in urbanized environments, urban design guided by justice, and the individual freedoms of animals.

Despite being one of the most dependable methods used by applied mathematicians and engineers in handling complex systems, the finite element method commits variational crimes. This paper contextualizes the concept of variational crime within a broader account of mathematical practice by explaining the tradeoff between complexity and accuracy involved in the construction of numerical methods.

This paper explores the role of iconicity in spoken language and other human communication systems. First, we concentrate on graphical and gestural communication and show how semantically motivated iconic signs play an important role in creating such communication systems from scratch. We then consider how iconic signs tend to become simplified and symbolic as the communication system matures and argue that this process is driven by repeated interactive use of the signs. We then consider evidence for iconicity at the level (...) of the system in graphical communication and finally draw comparisons between iconicity in graphical and gestural communication systems and in spoken language.

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)

This paper articulates an account of imperatives that sensibly supports the idea of a logic of imperative inferences. We rebuke common objections to the very possibility of such a logic, from a perspective based on recent linguistic work on the morphosyntax of imperatives. Specifically, we develop the notion that the content of an imperative sentence includes both a force operator alongside an imperational content to which the force applies. We further argue that this account of the content of imperatives constitutes (...) a plausible and flexible framework to develop a logic of imperative by examining a number of reconstructions of this idea using semantical analogs of widespread modal semantics. After studying the performance of those approaches, we conclude that progress in imperative logic has been hindered by the failure to adopt conflict-tolerant and resource-sensitive semantics, but suggest that such considerations can be incorporated in this flexible framework. Finally, we also propose a simple account of the difference between operators applying to the content of imperatives and imperative operators, in a way that sheds light on some of the issues underlying the usual antinomies.

We introduce a logic specifically designed to support reasoning about social choice functions. The logic includes operators to capture strategic ability, and operators to capture agent preferences. We establish a correspondence between formulae in the logic and properties of social choice functions, and show that the logic is expressively complete with respect to social choice functions, i.e., that every social choice function can be characterised as a formula of the logic. We prove that the logic is decidable, and give a (...) complete axiomatization. To demonstrate the value of the logic, we show in particular how it can be applied to the problem of determining whether a social choice function is strategy-proof. (shrink)
