Theory change is a central concern in contemporary epistemology and philosophy of science. In this paper, we investigate the relationships between two ongoing research programs providing formal treatments of theory change: the (post-Popperian) approach to verisimilitude and the AGM theory of belief change. We show that appropriately construed accounts emerging from those two lines of epistemological research do yield convergences relative to a specified kind of theories, here labeled “conjunctive”. In this domain, a set of plausible conditions are identified which (...) demonstrably capture the verisimilitudinarian effectiveness of AGM belief change, i.e., its effectiveness in tracking truth approximation. We conclude by indicating some further developments and open issues arising from our results. (shrink)

In this paper, we address the problem of truth approximation through theory change, asking whether revising our theories by newly acquired data leads us closer to the truth about a given domain. More particularly, we focus on “nomic conjunctive theories”, i.e., theories expressed as conjunctions of logically independent statements concerning the physical or, more generally, nomic possibilities and impossibilities of the domain under inquiry. We define both a comparative and a quantitative notion of the verisimilitude of such theories, and identify (...) suitable conditions concerning the (partial) correctness of acquired data, under which revising our theories by data leads us closer to “the nomic truth”, construed as the target of scientific inquiry. We conclude by indicating some further developments, generalizations, and open issues arising from our results. (shrink)

Popper’s original definition of truthlikeness relied on a central insight: that truthlikeness combines truth and information, in the sense that a proposition is closer to the truth the more true consequences and the less false consequences it entails. As intuitively compelling as this definition may be, it is untenable, as proved long ago; still, one can arguably rely on Popper’s intuition to provide an adequate account of truthlikeness. To this aim, we mobilize some classical work on partial entailment in defining (...) a new measure of truthlikeness which satisfies a number of desiderata. The resulting account has some interesting and surprising connections with other accounts on the market, thus shedding new light on current attempts of systematizing different approaches to verisimilitude.

We provide a 'verisimilitudinarian' analysis of the well-known Linda paradox or conjunction fallacy, i.e., the fact that most people judge the probability of the conjunctive statement "Linda is a bank teller and is active in the feminist movement" (B & F) as more probable than the isolated statement "Linda is a bank teller" (B), contrary to an uncontroversial principle of probability theory. The basic idea is that experimental participants may judge B & F a better hypothesis about Linda as compared (...) to B because they evaluate B & F as more verisimilar than B. In fact, the hypothesis "feminist bank teller", while less likely to be true than "bank teller", may well be a better approximation to the truth about Linda. (shrink)

We explore the grammar of Bayesian confirmation by focusing on some likelihood principles, including the Weak Law of Likelihood. We show that none of the likelihood principles proposed so far is satisfied by all incremental measures of confirmation, and we argue that some of these measures indeed obey new, prima facie strange, antilikelihood principles. To prove this, we introduce a new measure that violates the Weak Law of Likelihood while satisfying a strong antilikelihood condition. We conclude by hinting at some (...) relevant links between the likelihood principles considered here and other properties of Bayesian confirmation recently explored in the literature. (shrink)

Este artículo es parte de un proyecto mayor el cual busca usar conceptos de teoría de sistemas, complejidad y cibernética para poder crear modelos de comportamiento jurídico que puedan ser sujetos a modelaje y simulaciones computacionales, haciendo con ello que teoría y práctica sean más fáciles de interrelacionar. Debido a problemas de espacio, dos modelos del derecho serán ofrecidos al lector: uno sobre cómo es creado el conocimiento del derecho, la justicia, el Estado del derecho y cómo circula y otro (...) sobre qué son las normas, cómo se implementan y quiénes son sus sujetos. El trabajo que se ofrece en este estudio se correlaciona con el enfoque socio-empírico del Law and Society. Concluyo que teoría y práctica tiene una relación recursiva: la teoría sin referente práctico es ficción y práctica sin teoría es un desarrollo a ciegas; el modelaje a computadora es una forma de mejorar la relación complementaria que ambas deben tener.

Starting with Popper, philosophers and logicians have proposed different accounts of verisimilitude or truthlikeness. One way of classifying such accounts is to distinguish between “conjunctive” and “disjunctive” ones. In this paper, we focus on our own “basic feature” approach to verisimilitude, which naturally belongs to the conjunctive family. We start by surveying the landscape of conjunctive accounts; then, we introduce two new measures of verisimilitude and discuss their properties; finally, we conclude by hinting at some surprising relations between our conjunctive (...) approach and a disjunctive account of verisimilitude widely discussed in the literature.

A survey of some game-theoretic accounts of the emergence and evolution of spontaneuous cooperation in social and public-good dilemmas.

This is the introductory essay to the Italian translation of Matt Ridley's "The origins of virtue", surveying the game-theoretic and evolutionary approaches to the emergence and evolution of cooperation and altruism.

The paper focuses on Anthony de Jasay's "anarcho-liberalism" as based oon his game-theoretic approach to the problem of public goods provision.

The Linda paradox is a key topic in current debates on the rationality of human reasoning and its limitations. We present a novel analysis of this paradox, based on the notion of verisimilitude as studied in the philosophy of science. The comparison with an alternative analysis based on probabilistic confirmation suggests how to overcome some problems of our account by introducing an adequately defined notion of verisimilitudinarian confirmation.

The basic problem of a theory of truth approximation is defining when a theory is “close to the truth” about some relevant domain. Existing accounts of truthlikeness or verisimilitude address this problem, but are usually limited to the problem of approaching a “deterministic” truth by means of deterministic theories. A general theory of truth approximation, however, should arguably cover also cases where either the relevant theories, or “the truth”, or both, are “probabilistic” in nature. As a step forward in this (...) direction, we first present a general characterization of both deterministic and probabilistic truth approximation; then, we introduce a new account of verisimilitude which provides a simple formal framework to deal with such issue in a unified way. The connections of our account with some other proposals in the literature are also briefly discussed. (shrink)

En este artículo nos proponemos analizar la demostración de la existencia de Dios dada por Kant en dos de sus obras precríticas, en las cuales se postula la necesidad funcional del _fundamento_ material como enlace entre la realidad propositiva (determinaciones de realidad) y la _posibilidad_ de los particulares. Este fundamento material aparece como condición necesaria para el contenido del pensamiento, o la determinación de los conceptos. Como foco de análisis tenemos las siguientes dos obras: la _Nueva dilucidación sobre los primeros (...) principios del conocimiento metafísico_ de 1755, y _El único argumento posible para una demostración de la existencia de Dios_, de 1763. Nos proponemos señalar la continuidad conceptual y argumentativa entre estas obras en lo que respecta a las determinaciones de realidad. A su vez, nos interesa detenernos en dos conceptos que refieren a Dios, que son centrales en el argumento ontológico kantiano, y que serán retomados por el propio Kant en la _Crítica de la razón pura_; estos conceptos son _omnitudo realitatis_ (totalidad de la realidad) y _die höchste Realität_ (la suma realidad).

From a hermeneutical position, the article examines why tension is created between «method» on one hand and circularity on the other. The latter, being unity as well, is the foundation of natural hermeneutics of which it has been said that to be human is to interpret. With this purpose in view, the author has sought to restore to essential Greek terms their archaic meaning which centuries of vernacular usage have rendered blurry, finding that, in accordance with the Greek symbolon, man's (...) conscience of «I am Here and Now» is symbolic unity, viz. a strained unity in search of The Superior Unity that makes him Methodos, Circle, His Own Future, and Metaphysics.

We aimed to characterize the age of onset of training, age at menarche, menstrual periodicity, and performance perception during the menstrual cycle and examined the impact of these reproductive variables on body composition, morphology, and body weight satisfaction in Brazilian elite futsal players. The study consisted of 115 female Brazilian elite futsal players from the top national teams. Data were collected during the twentieth Women’s Brazil Futsal Cup. Players were interviewed and self-reported their age of onset of training, age at (...) menarche, menstrual periodicity, and the menstrual period, where they performed best. We also asked for what they considered to be their ideal body weight as well as information related to their training. Subsequently, anthropometric measurements were performed to estimate the body composition and determine morphological characteristics. Fifty-nine players were postmenarche-trained and 52 were premenarche-trained. Eighteen, 65, and 28 were classified as early, normal, and late menarche, respectively. Only 11 and 1 had irregular menstrual cycles and were amenorrheic, respectively. Seventy-three, 23, and 9 reported that their game performance was the best at the follicular phase, menses, and luteal phase of the menstrual cycle, respectively. No associations between the four reproductive-related variables were found. Postmenarche-trained players had significant lower age at menarche and higher percentage body fat. The somatotype profile registered lower ectomorphy rate for the postmenarche-trained participants after controlling for covariates. Early menarche group presented higher sum of six skinfold thickness and endomorphy rate compared to normal and late menarche groups. No differences were found when menstrual periodicity groups and best performance groups were compared, except for higher femur width in the regular menstrual cycle group compared to the irregular one. The association between body weight satisfaction and the four reproductive-related variables were not observed. Premenarche-trained Brazilian elite futsal players had the menarche later than the postmenarche-trained athletes. Most of the participants had menarche age classified as “normal,” presented “regular” menstrual cycles and perceived to perform better during the follicular phase of the menstrual cycle. (shrink)

Review of Olsson, Erik J. and Enqvist, Sebastian , Belief Revision meets Philosophy of Science.

Mark Platts is responsible for the first systematic presentation of truth-conditional semantics and for turning a generation of philosophers on to the Davidsonian program. He is also a pioneer in discussions of moral realism, and has made important contributions to bioethics, the philosophy of human rights and moral responsibility. This book is a tribute to Platts's pioneering work in these areas, featuring contributions from number of leading scholars of his work from the US, UK and Mexico. It features replies to (...) the individual essays from Platts, as well as a concluding chapter reflecting on his philosophical career from Oxford to Mexico City. Mind, Language and Morality will be of interest to philosophers across a wide range of areas, including ethics, moral psychology, philosophy of law, and philosophy of language. (shrink)

RESUMEN Largamente desatendida o malinterpretada, la noción de caos en la filosofía de Nietzsche es una pieza constitutiva de la particular concepción del ser que este autor habría dejado apenas esbozada. El artículo se propone elaborar este concepto en la obra nietzscheana, siguiendo algunas de las metáforas que lo iluminan. Desde allí se busca plantear los rasgos centrales de una ontologia del caos, de sesgo no metafísico, que, al afirmar el carácter acontecimental de la realidad, puede verse como precursora de (...) la ontología hermenéutica contemporánea. ABSTRACT The notion of chaos, which has long been neglected or misinterpreted, is a constitutive element of a peculiar conception of being that the philosopher only had time to outline. The objective of this article is to elaborate on this concept in Nietzschean philosophy, guided by some of the metaphors that shed light on it. This serves as the basis to set forth the main characteristics of a non-metaphysical ontology of chaos that asserts the eventful nature of reality and can thus be seen as a precursor of contemporary hermeneutic ontology.

Emotional intelligence is a psychological skill that aids athletes in the control of emotions and optimization of sports performance. The present study investigated the psychometric properties of the Self-Report Emotional Intelligence Test in 508 Brazilian youth and adult athletes. Data analysis was conducted through Exploratory and Confirmatory Factor Analysis, Cronbach’s alpha, composite reliability and Pearson’s Correlation. EFA revealed the one-factor model with 26 items with the best adjustment. CFA confirmed the one-factor model with 26 items with best greater fit. No (...) evidence of invariance was found, suggesting that the SSEIT must be used with caution when comparing gender and age groups. The external validity was found in the correlation of EI and cognitive anxiety and self-confidence. It is concluded that the Brazilian version of SSEIT for the sports context presented acceptable psychometric properties, however, showed limitations that should be explored in the future. (shrink)

Fundado na obra de José Roberto Dromi, que estabelece as características do “constitucionalismo do futuro”, o presente trabalho busca delinear as características do novo constitucionalismo latino americano e traçar um paralelo entre os dois. Para tanto, através de uma abordagem dedutiva, será realizada uma pesquisa bibliográfica e estudo comparado das constituições latinas. Os pensamentos anticolonialistas são fundamentos desse novo modo de pensar o constitucionalismo, que devolve o poder ao povo, sustentando um Estado plurinacional, promovendo uma verdadeira refundação estatal. Esse (...) modelo, que parte da prática para a teoria, ainda está sendo formatado, mas apresenta avanços inegáveis em relação ao constitucionalismo. (shrink)

The role played by the movement of the ‘novatores’ determined the introduction of philosophical scientific European thought in Spain and was essential for the later development of Enlightment in Spain. Juan de Nájera represented the standard of modern thinker at the begining of the century and he intended to reconcile modern ideas with more traditional positions. He was a very example of a trend shared by most ‘novatores’ in early Eighteenth Century in Spain.

There are communities in which disadvantaged groups experience severe inequality. For instance, poor and indigent families face many difficulties accessing their social rights. Their condition is largely the consequence of the wrong choices of those in power, either historical or more recent choices. The lack of opportunities of these deprived citizens is due to state omissions. In such communities, it is not unusual for homeless members of these particular groups to occupy abandoned lands and build their shelters there. However, almost (...) everywhere, these actions constitute a crime. The typical response to this situation is prosecution and punishment. In this paper, I will defend the occupation of public places as a consequence of the failure of governments to solve the problem of housing, and I will argue that we must distinguish a social claim from a crime and avoid the use of criminal law in these “occupation cases”. I will also argue that our right—as a community—to blame and punish these “squatters” is eroded by the fact that we perpetrated their situation of injustice. (shrink)

This study examines how multinational corporations (MNCs) from the retail sector deal with four challenges they face when adopting Corporate Social Responsibility (CSR) policies: the challenge of developing well-performing CSR projects and programs, building competitive advantages based on CSR, responding to local stakeholder issues in the host countries and learning from different CSR experiences on a worldwide basis. Based on in-depth case studies of two globally leading retail MNCs (with strong operations in Latin America), the concept of Transverse CSR Management (...) emerged. Transverse CSR Management is defined as a distinctive form of organizational configuration that crosses different functional areas, country operations, and the boundaries of the firm. In particular, this article makes three main contributions: (1) we identify four central challenges faced by MNC managers when developing their CSR strategies; (2) we propose the concept of Transverse CSR Management to face these central challenges (together, at the same time) and identify its key elements (top management, external stakeholders, functional areas, and country subsidiaries); and (3) we propose four mechanisms (hierarchical, relational, cultural, and collaborative) through which the concept of Transverse CSR Management can be implemented by practicing managers. This study provides valuable insights for MNC managers in headquarters and subsidiaries on the issues they need to address in order to successfully deal with the four CSRrelated challenges. (shrink)

There is a large gap between the specialized knowledge of scientists and laypeople’s understanding of the sciences. The novice-expert problem arises when non-experts are confronted with (real or apparent) scientific disagreement, and when they don’t know whom to trust. Because they are not able to gauge the content of expert testimony, they rely on imperfect heuristics to evaluate the trustworthiness of scientists. This paper investigates why some bodies of scientific knowledge become polarized along political fault lines. Laypeople navigate conflicting epistemic (...) and social demands in their acceptance of scientific testimony; this might explain their deference to scientific fringe theories, which often goes together with denying established scientific theories. I evaluate three approaches to mitigate denialism: improving the message, improving the messenger, and improving the environment in which the message is conveyed. (shrink)

Dung’s argumentation frameworks have been applied for over twenty years to the analysis of argument justification. This representation focuses on arguments and the attacks among them, abstracting away from other features like the internal structure of arguments, the nature of utterers, the specifics of the attack relation, etc. The model is highly attractive because it reduces most of the complexities involved in argumentation processes. It can be applied to different settings, like the argument evaluation of an individual agent or the (...) case of dialectic disputes between two agents (pro and con), or even in multi-agent collective argumentation. The latter case involves agents with possibly different arguments and/or opinions on how to evaluate them, leading to the possibility of considering multiple sets of arguments and attack relations. Two basic questions can be asked here, namely ‘what to aggregate’ and ‘how to aggregate’. The former concerns what kinds of entities do the agents intend to choose (arguments, attacks, assessments, etc.), while the second one focuses on which aggregation mechanisms yield rational choices (voting on arguments, merging procedures to obtain a common argumentation framework, deliberation processes, etc.). In particular, the question about the rationality of a collective argument choice relates this topic to Social Choice and Judgment Aggregation theories, while its associated strategic issues relate it to Game Theory. The research efforts on the disparate problems elicited by collective argumentation have generated a considerable corpus of literature that deserves an orderly evaluation. This survey is intended as a contribution to that end. (shrink)

A critical survey of the main philosophical theories about events and event talk, organized in three main sections: (i) Events and Other Categories (Events vs. Objects; Events vs. Facts; Events vs. Properties; Events vs. Times); (ii) Types of Events (Activities, Accomplishments, Achievements, and States; Static and Dynamic Events; Actions and Bodily Movements; Mental and Physical Events; Negative Events); (iii) Existence, Identity, and Indeterminacy.

The problems that arise from the presence of self-attacking ar- guments and odd-length cycles of attack within argumentation frameworks are widely recognized in the literature on defeasible argumentation. This paper introduces two simple semantics to capture different intuitions about what kinds of arguments should become justified in such scenarios. These semantics are modeled upon two extensions of argumentation frameworks, which we call sustainable and tolerant. Each one is constructed on the common ground of the powerful concept of admissibility introduced by (...) Dung in [10]. The novelty of this approach consists in viewing the admissibility of a subset of arguments as relative to potentially challenging subsets of arguments. Both sustainable and tolerant semantics are more credulous than preferred semantics (i.e. they justify at least the same arguments, and possibly more). Given certain sufficient conditions they coincide among them as well as with other semantics introduced by Dung. (shrink)

In this paper we provide a compact presentation of the verisimilitudinarian approach to scientific progress (VS, for short) and defend it against the sustained attack recently mounted by Alexander Bird (2007). Advocated by such authors as Ilkka Niiniluoto and Theo Kuipers, VS is the view that progress can be explained in terms of the increasing verisimilitude (or, equivalently, truthlikeness, or approximation to the truth) of scientific theories. According to Bird, VS overlooks the central issue of the appropriate grounding of scientific (...) beliefs in the evidence, and it is therefore unable (a) to reconstruct in a satisfactory way some hypothetical cases of scientific progress, and (b) to provide an explanation of the aversion to falsity that characterizes scientific practice. We rebut both of these criticisms and argue that they reveal a misunderstanding of some key concepts underlying VS. (shrink)
