La investigación sobre el trazado intelectual de las rutas latinas europeas hacia la península ibérica con anterioridad al s. XIII está aportando algunos hallazgos particularmente interesantes. En este artículo se aborda un estudio de caso vinculado a la transmisión e intercambio del saber que, muy lejos de haber sido desentrañado, continúa apareciendo como un problema complejo que requiere de nuevas aproximaciones epistemológicas ‒si lo que se pretende es alcanzar un encuadre congruente del problema. El estudio de las rutas de intercambio (...) intelectual en la península ibérica en los siglos IX-XII ‒fundamentalmente, textos doctrinales latinos en circulación dentro del territorio de al-Andalus y entre comunidades de cristianos arabizados‒ nos lleva a pensar que algunas de las conclusiones que se habían propuesto sobre las influencias doctrinales presentes en el Tathlīth al-waḥdāniyyah no pueden constatarse: poner en relación la Theologia Summi boni de Pedro Abelardo con la tríada “poder” (qudrah), “conocimiento” (ʿilm) y “voluntad” (irādah) que el anónimo autor emplea para caracterizar los atributos de las tres personas de la Trinidad. Se han propuesto nuevas hipótesis sobre una vía de influencia que llegaría a través de la tríada empleada por Hugo de san Víctor en el De tribus diebus, cuya línea de influencia habría que situarla en la tríada empleada por Ambrosio de Milán, tal y como ha sido planteado por Dominique Poirel. No obstante, investigaciones más recientes proponen nuevas vías de penetración doctrinal en la Península que, en cierto modo, comparten la tríada de Ambrosio pero que habrían llegado a la Península (al-Andalus en particular) por vías de intercambio textual y doctrinal procedentes de Oriente Próximo y de origen griego. A lo largo de este trabajo se presentan hipótesis y resultados llevados a cabo en investigaciones previas, así como una recapitulación e hipótesis de investigaciones en curso. Se trata de una nota de investigación que no posee un carácter conclusivo, antes bien, pretende aportar nuevas vías de aproximación al problema. (shrink)

El análisis sobre la conocida posición de Mariano Menéndez Pelayo en torno a los mozárabes del siglo IX, podría ser tratado como un estudio de caso donde se pone de manifiesto una de las muchas instancias de persistente tradicionalismo ideológico que podemos encontrar en la historiografía española del siglo XIX ‒el artículo analiza algunas de sus raíces e implicaciones.

Quelle est la légitimité de l'expression "philosophie présocratique"? Des philosophes, des historiens de la philosophie, des philologues, mais aussi des historiens et des anthropologues se sont intéressés à ce pan de la pensée grecque lors d'un congrès tenu en octobre 2000 à la Maison de la recherche de l'université Charles-de-Gaulle-Lille. Ce volume en reprend les contributions.

Brian Cutter objected to the consequence argument due to its dependence on the principle that miracle workers are metaphysically impossible. A miracle worker is someone who has the ability to act in a way such that the laws of nature would be violated. While there is something to the thought that agents like us do not have this ability, Cutter claims that there is no compelling reason to regard miracle workers as metaphysically impossible. However, the paper contends that miracle workers (...) are indeed impossible according to well-known theories concerning the laws of nature. This result highlights the reliance of the consequence argument on a plausible premise, which is widely accepted by proponents of non-Humean views of laws. The paper also provides a way to explain away the intuition that miracle workers are possible, but this has the upshot that a recent, two-dimensional formulation of the consequence argument is unsound.

How should we make decisions when we do not know the relevant physical probabilities? In these ambiguous situations, we cannot use our knowledge to determine expected utilities or payoffs. The traditional Bayesian answer is that we should create a probability distribution using some mix of subjective intuition and objective constraints. Imprecise Bayesians argue that this approach is inadequate for modelling ambiguity. Instead, they represent doxastic states using credal sets. Generally, insofar as we are more uncertain about the physical probability of (...) an event, there is more divergence in the credal set. Hence, their approach can represent these ambiguities via the extent of the divergence. Imprecise Bayesianism has mostly been advocated for its epistemological features. In this article, we examine its properties for decision-making. We develop a model for comparing standard and Imprecise Bayesianism by testing their performances in a classic decision problem. We find that the representational tools of Imprecise Bayesianism also cause it to underperform in our tests. This issue has been overlooked, because previous research on Imprecise Bayesianism has not utilised agent-based modelling to provide information about its performance in the short-run. Overall, we reveal the Ambiguity Dilemma for Imprecise Bayesianism: To what extent should one value representational power or decision-making performance? (shrink)

The article sets out to reinterpret Heraclitus' views on religion and, by implication, his position in the context of the Presocratic philosophers' relationship to the Greek cultural tradition. It does so by examining the fragments in which Heraclitus' attitude to the popular religion of his time is reflected. The analysis of the fragments 69, 68, 15, 14, 5, 96, 93 and 92 DK reveals that the target of Heraclitus' criticism is not the religious practices themselves, but their popular interpretation. Heraclitus' (...) fragments are simultaneously shown to identify the underlying structure of the 'unity of opposites,' inherent in various religious practices. Heraclitus appears to reinterpret religious practices in terms of the conceptual structures of his own philosophy. On the other hand, religion provides him with the categories for the construction of his philosophical theology. Thus Heraclitus' treatment of religion is shown to be analogous to his treatment of ethics and politics, which he also tries to incorporate into his highly integrated vision of reality. In contrast to Xenophanes' radical critique of the traditional religion, Heraclitus emerges not as a reformer or an Aufklärer , but as an interpreter, who tries to discern the structures of meaning inherent in the existing practices, and to assume them into his own philosophical project.

The debates between Bayesian, frequentist, and other methodologies of statistics have tended to focus on conceptual justifications, sociological arguments, or mathematical proofs of their long run properties. Both Bayesian statistics and frequentist (“classical”) statistics have strong cases on these grounds. In this article, we instead approach the debates in the “Statistics Wars” from a largely unexplored angle: simulations of different methodologies’ performance in the short to medium run. We conducted a large number of simulations using a straightforward decision problem based (...) around tossing a coin with unknown bias and then placing bets. In this simulation, we programmed four players, inspired by Bayesian statistics, frequentist statistics, Jon Williamson’s version of Objective Bayesianism, and a player who simply extrapolates from observed frequencies to general frequencies. The last player functions as a benchmark: a statistical methodology should at least outperform a crude form of induction. We focused on the performance of these methodologies in guiding the players towards good decisions. Unlike an earlier simulation study of this type, we found no systematic difference in performance between the Bayesian and frequentist players, provided the Bayesian used a flat prior and the frequentist used a low confidence level. Unlike that study, we were able to use Big Data methods to mitigate problems of random error in the simulation results. The Williamsonian player, who is a novel element of our study, also had no systematic differences in their performance, provided that they use a low confidence level. These players performed similarly even in the very short run, when players were making different decisions. Our study indicates that all three methodologies should be taken seriously by philosophers and practitioners of statistics. However, the frequentist and Williamsonian performed poorly when their confidence levels were high, and the Bayesian was surprisingly harmed by biased priors, providing some unexpected lessons for these methodologies when facing this type of decision problem.

The game theoretic notion of best-response reasoning is sometimes criticized when its application produces multiple solutions of games, some of which seem less compelling than others. The recent development of the theory of team reasoning addresses this by suggesting that interacting players in games may sometimes reason as members of a team – a group of individuals who act together in the attainment of some common goal. A number of properties have been suggested for team-reasoning decision-makers’ goals to satisfy, but (...) a few formal representations have been discussed. In this paper we suggest a possible representation of these goals based on the notion of mutual advantage. We propose a method for measuring extents of individual and mutual advantage to the interacting decision-makers, and define team interests as the attainment of outcomes associated with maximum mutual advantage in the games they play.

Calibration inductive logics are based on accepting estimates of relative frequencies, which are used to generate imprecise probabilities. In turn, these imprecise probabilities are intended to guide beliefs and decisions — a process called “calibration”. Two prominent examples are Henry E. Kyburg's system of Evidential Probability and Jon Williamson's version of Objective Bayesianism. There are many unexplored questions about these logics. How well do they perform in the short-run? Under what circumstances do they do better or worse? What is their (...) performance relative to traditional Bayesianism? -/- In this article, we develop an agent-based model of a classic binomial decision problem, including players based on variations of Evidential Probability and Objective Bayesianism. We compare the performances of these players, including against a benchmark player who uses standard Bayesian inductive logic. We find that the calibrated players can match the performance of the Bayesian player, but only with particular acceptance thresholds and decision rules. Among other points, our discussion raises some challenges for characterising “cautious” reasoning using imprecise probabilities. Thus, we demonstrate a new way of systematically comparing imprecise probability systems, and we conclude that calibration inductive logics are surprisingly promising for making decisions. (shrink)

Contemporary debates about scientific institutions and practice feature many proposed reforms. Most of these require increased efforts from scientists. But how do scientists’ incentives for effort interact? How can scientific institutions encourage scientists to invest effort in research? We explore these questions using a game-theoretic model of publication markets. We employ a base game between authors and reviewers, before assessing some of its tendencies by means of analysis and simulations. We compare how the effort expenditures of these groups interact in (...) our model under a variety of settings, such as double-blind and open review systems. We make a number of findings, including that open review can increase the effort of authors in a range of circumstances and that these effects can manifest in a policy-relevant period of time. However, we find that open review’s impact on authors’ efforts is sensitive to the strength of several other influences. (shrink)

Information Retrieval systems benefit from the use of long queries containing a large volume of search-relevant information. This situation is not common, as users of such systems tend to use very short and precise queries with few keywords. In this work we propose a modification of the Latent Dirichlet Allocation (LDA) technique using data from the document collection and its vocabulary for a better representation of short queries. Additionally, a study is carried out on how the modification of the proposed (...) LDA weighted vectors increase the performance using relevant documents as feedback. The work shown in this paper is tested using three biomedical corpora (TREC Genomics 2004, TREC Genomics 2005 and OHSUMED) and one legal corpus (FIRE 2017). Results prove that the application of the proposed representation technique, as well as the feedback adjustment, clearly outperforms the baseline methods (BM25 and non-modified LDA). (shrink)

O artigo analisa, a partir sobretudo do pensamento de Hannah Arendt, o desafio que representa para a política “viver junto”. Embora a expressão origine-se com o ensaísta francês Roland Barthes, o objetivo do artigo é quadruplo: (1) apresentar seu fundamento ontológico na condição humana ou existencial de “ser-com”, ou seja, de ser junto aos outros, pensada desde Martin Heidegger; (2) descrever seu sentido político pela conjugação entre isonomia e diferença na forma da pluralidade pela qual cada pessoa pode aparecer singularmente (...) em atos e palavras, de acordo com uma liberdade frente a quaisquer predeterminações; (3) demonstrar como a recente situação da pandemia de Covid-19 radicalizou o impasse de viver junto – e separado – em sociedade, particularmente no caso do Brasil, colocando em relevo uma dimensão coletiva da liberdade pela interdependência entre os seres humanos; e (4) apontar a importância da forma de governo da república, mas também os perigos da sua fragilização nas democracias contemporâneas no que se refere à dificuldade de responder – como viver junto?

We offer a review of some of the most influential views on the status of Reichenbach’s Principle of the Common Cause (PCC) for genuinely indeterministic systems. We first argue that the PCC is properly a conjunction of two distinct claims, one metaphysical and another methodological. Both claims can and have been contested in the literature, but here we simply assume that the metaphysical claim is correct, in order to focus our analysis on the status of the methodological claim. We briefly (...) review the most entrenched or classical positions, including Salmon’s ‘interactive forks’, van Fraassen’s scepticism, and Cartwright’s generalisation of the fork criterion. We then go on to review the results of the ‘Budapest school’ on the existence of formally defined screening-off events for any correlation —by means of the ideas of probability space extensibility and (Reichenbachian common cause) completability. We distinguish the Budapest doctrine clearly from any of the classical conceptions, and thus present an overall framework for discussions of causal inference in quantum mechanics. The framework, however preliminary, is essential work for a thorough assessment of the conditions under which PCC may be a reliable tool for causal inference in a genuinely probabilistic (indeterministic) context.

Virtual bargaining theory suggests that social agents aim to resolve non-cooperative games by identifying the strategy profile which they would agree to play if they could openly bargain. The theory thus offers an explanation of how social agents resolve games with multiple Nash equilibria. One of the main questions pertaining to this theory is how the principles of the bargaining theory could be applied in the analysis of hypothetical bargaining in non-cooperative games. I propose a bargaining model based on the (...) benefit-equilibrating bargaining solution concept for non-cooperative games, broadly in line with the principles underlying Conley and Wilkie's ordinal egalitarian solution for Pareto optimal point selection problems with finite choice sets. I provide formal characterizations of the ordinal and the cardinal versions of BES, discuss their application to n-player games, and compare model's theoretical predictions with the data available from several experiments involving `pie games'.

In 1986 David Gauthier proposed an arbitration scheme for two player cardinal bargaining games based on interpersonal comparisons of players’ relative concessions. In Gauthier’s original arbitration scheme, players’ relative concessions are defined in terms of Raiffa-normalized cardinal utility gains, and so it cannot be directly applied to ordinal bargaining problems. In this paper I propose a relative benefit equilibrating bargaining solution for two and n-player ordinal and quasiconvex ordinal bargaining problems with finite sets of feasible basic agreements based on the (...) measure of players’ ordinal relative individual advantage gains. I provide an axiomatic characterization of this bargaining solution and discuss the conceptual relationship between RBEBS and ordinal egalitarian bargaining solution proposed by Conley and Wilkie. I show the relationship between the measurement procedure for ordinal relative individual advantage gains and the measurement procedure for players’ ordinal relative concessions, and argue that the proposed arbitration scheme for ordinal games can be interpreted as an ordinal version of Gauthier’s arbitration scheme.

This paper is dedicated to the analysis of the maximin principle, which is one of the key theoretical concepts of John Rawls’s theory of justice, and the problem that this principle creates for any attempt to provide a naturalistic interpretation of Rawls’s concept of fairness . Analysis shows that maximin principle is, in fact, incompatible with the Bayesian decision theory. This paper is intended to show that recent breakthroughs in evolutionary game theory could help to reconcile the maximin principle with (...) a certain naturally emerging and evolutionary stable pattern of human social behaviour.Keywords: Maximin principle, Nash bargaining game, Evolutionary Game Theory, Evolutionary Stable Strategy, learning rules.

One of the conceptual limitations of the orthodox game theory is its inability to offer definitive theoretical predictions concerning the outcomes of noncooperative games with multiple rationalizable outcomes. This prompted the emergence of goal-directed theories of reasoning – the team reasoning theory and the theory of hypothetical bargaining. Both theories suggest that people resolve non-cooperative games by using a reasoning algorithm which allows them to identify mutually advantageous solutions of non-cooperative games. The primary aim of this thesis is to enrich (...) the current debate on goaldirected reasoning theories by studying the extent to which the principles of the bargaining theory can be used to formally characterize the concept of mutual advantage in a way which is compatible with some of the conceptually compelling principles of orthodox game theory, such as individual rationality, incentive compatibility, and non-comparability of decision-makers’ personal payoffs. I discuss two formal characterizations of the concept of mutual advantage derived from the aforementioned goal-directed reasoning theories: A measure of mutual advantage developed in collaboration with Jurgis Karpus, which is broadly in line with the notion of mutual advantage suggested by Sugden, and the benefit-equilibrating bargaining solution function, which is broadly in line with the principles underlying Conley and Wilkie’s solution for Pareto optimal point selection problems with finite choice sets. I discuss the formal properties of each solution, as well as its theoretical predictions in a number of games. I also explore each solution concept’s compatibility with orthodox game theory. I also discuss the limitations of the aforementioned goal-directed reasoning theories. I argue that each theory offers a compelling explanation of how a certain type of decision-maker identifies the mutually advantageous solutions of non-cooperative games, but neither of them offers a definitive answer to the question of how people coordinate their actions in non-cooperative social interactions.

In the context of business, interactions between individuals generate social systems that emerge anywhere within a corporation or in its relations with external agents. These systems influence the behaviors of individuals and, as a result, the collective actions we usually attribute to corporations. Social systems thus make a difference in processes of action that are often morally evaluated by internal and external agents to the firm. Despite this relevance, social systems have not yet been the object of specific attention in (...) the literature on moral agency in business. To fill this gap, I construct a theoretical framework based on Luhmann’s ideas on social systems and morality. In particular, I argue that morality is a phenomenon that occurs in communication, and an agent can engage in morality in three different ways (as a _moral factor_, an _expressive moral agent_, or a _reflective moral agent_) depending on the functions it plays in communicative interactions. Based on this framework, I argue that social systems in business can be considered moral agents of those types. (shrink)

Este artigo tem como objetivo principal analisar o pensamento desenvolvido por Georges Canguilhem e Gilbert Simondon sobre dois conceitos principais: o conceito de organismo e de máquina. A intenção é de reconstruir, a partir das continuidades e descontinuidades entre os dois conceitos, o raciocínio desenvolvido pelos dois autores sobre esses temas na história da filosofia francesa do século passado. Assim, tomamos como escopo as obras La connaissance de la vie, publicada por Canguilhem em 1952 e a tese complementar de doutoramento (...) de Simondon, orientada por Canguilhem, Du mode d’existence des objets techniques, de 1958. A partir disso, o texto se divide em seis partes: uma introdução, onde damos as especificações de escopo e de análise, seguida pela primeira parte, onde analisamos os conceitos de pensamento, conhecimento, sujeito e objeto. Em seguida, na parte dois, analisamos os conceitos de máquina, mecanismo e motor, como utilizadas em Canguilhem, e os conceitos de indivíduo, elemento e conjunto técnico desenvolvidas por Simondon. A terceira parte se dedica a analisar a questão do autômato, bem como os conceitos de mecanismo e finalismo. A quarta parte desenvolve o conceito de organismo-máquina e os conceitos de potencialidade e de teleologia desenvolvidos principalmente em Canguilhem. Por fim, na conclusão, analisamos as aproximações e distâncias entre os dois autores, bem como a imagem do monstro e do robô. (shrink)

La discusión sobre las consecuencias políticas del pensamiento de L. Wittgenstein ha girado sobre la posibilidad de construir miradas críticas sobre lo social, su legitimidad, amplitud, fuerza, etc. Sin embargo, aproximar a Wittgenstein a una posición materialista, como la entendía L. Althusser, conduce a una comprensión diferente de la crítica, vinculada a la tarea de deconstruir el discurso filosófico que intenta unificar y organizar jerárquicamente las evidencias (certezas) constitutivas de los diferentes juegos de lenguaje en los que se despliega lo (...) social. Se intenta extraer de esta aproximación una distinción entre la filosofía como práctica teórica ideológica y como práctica teórica crítica. The discussion regarding the political consequences of Wittgenstein's thought has focused on the possibility of building critical approaches to the legitimacy, amplitude, strength, etc. of the social sphere. However, bringing Wittgenstein close to a materialist position as understood by L. Althusser leads to a different understanding of critique, linked to the deconstruction of the philosophical discourse that attempts to unify and hierarchically organize the certainties that are constitutive of the different language games in which the social is deployed. On the basis of this approach, the article attempts to draw a distinction between philosophy as ideological theoretical practice and as critical theoretical practice. (shrink)

David Hume’s historical thought was shaped before he even began writing the History of Great Britain in 1752. This article shows how Hume developed his historical thought in an attempt to combine two historical structures: the natural-jurisprudential conjectural history of the Treatise of Human Nature and the early eighteenth-century historical narratives of modern Europe that featured in his Essays. The Treatise’s conjectural history used the developmental categories “rude” and “civilised” to explain the origins of justice, government and the moral sentiment. (...) The narratives of modern Europe, in contrast, revolved around the historical categories “ancient” and “modern.” Hume’s historical thought was shaped by the attempt to merge those two structures into a single, coherent structure. The critical question concerned the relation between the ancient and the modern: was modern Europe merely a “revival” of classical antiquity? Or did it have new, “post-ancient” dimensions? The article shows how Hume gradually distanced classical antiquity from modern Europe, thereby creating space for exclusively modern concepts such as “civilised monarchies” and the narrative of modern civilisation that structured his History of England (1754–1762). The paper concludes by suggesting that this structure defined Enlightenment philosophical history, not just Hume’s version of it. (shrink)

Este artigo discute como os conceitos de mediação e representação se articulam na reflexão de Carl Schmitt em alguns de seus primeiros escritos e preparam o terreno para a formulação da ideia de representação política em um de seus trabalhos mais conhecidos: Teoria da Constituição. O procedimento mediante o qual se traduz uma realidade amorfa ou um coletivo em forma de representação política se atém à noção de presentificar algo ausente ou tornar visível algo invisível. Toda ideia entra no mundo (...) empírico como hóspede forasteiro e para ganhar existência ou visibilidade necessita de uma decisão soberana pela sua representação. A finalidade deste estudo é explicar o modo pelo qual ocorre este procedimento. (shrink)

v. 1. Olhar sociológico pós-moderno -- v. 2. Insolúvel busca de solução -- v. 3. Felicidade possível.

En este artículo se ensaya un análisis de los presupuestos, de las consecuencias, que entraña la concepción cartesiana del saber. Y se llega a la conclusión de que toda la reflexión de Descartes se puede leer también como una filosofía de la historia en la que está la raíz de la idea moderna (y contemporánea) de progreso.
