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.

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.

Decolonization revolutionized the international order during the twentieth century. Yet standard histories that present the end of colonialism as an inevitable transition from a world of empires to one of nations—a world in which self-determination was synonymous with nation-building—obscure just how radical this change was. Drawing on the political thought of anticolonial intellectuals and statesmen such as Nnamdi Azikiwe, W.E.B Du Bois, George Padmore, Kwame Nkrumah, Eric Williams, Michael Manley, and Julius Nyerere, this important new account of decolonization reveals the (...) full extent of their unprecedented ambition to remake not only nations but the world. Adom Getachew shows that African, African American, and Caribbean anticolonial nationalists were not solely or even primarily nation-builders. Responding to the experience of racialized sovereign inequality, dramatized by interwar Ethiopia and Liberia, Black Atlantic thinkers and politicians challenged international racial hierarchy and articulated alternative visions of worldmaking. Seeking to create an egalitarian postimperial world, they attempted to transcend legal, political, and economic hierarchies by securing a right to self-determination within the newly founded United Nations, constituting regional federations in Africa and the Caribbean, and creating the New International Economic Order. Using archival sources from Barbados, Trinidad, Ghana, Switzerland, and the United Kingdom, Worldmaking after Empire recasts the history of decolonization, reconsiders the failure of anticolonial nationalism, and offers a new perspective on debates about today’s international order.

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)

This essay explores the possibilities and limits of decentering Europe by examining the Haitian Revolution and contemporary invocations of its legacy among political theorists and historians. Recent accounts of the Haitian Revolution have celebrated its universalism as a realization of French revolutionary ideals. As I argue in the essay, this interpretation undermines the Haitian Revolution’s specificity as the first and only successful revolution against colonial slavery. I offer an alternative interpretation that begins from the specificity of colonial slavery and explores (...) how Haitian revolutionaries inaugurated another universalism linked to individual and collective autonomy. Haitian revolutionaries offered a radical account of black citizenship and envisioned a world order in which both slavery and colonial rule would be transcended. This reinterpretation of the Haitian Revolution offers an alternative approach to what it might mean to decenter Europe—one that begins from the specific political problems subaltern actors encountered and illustrates how ideals are remade in diverse contexts.

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)

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.

This essay seeks to consider Anna Stilz's Territorial Sovereignty: A Philosophical Exploration in light of settler and nonsettler colonialism and their contemporary legacies. In particular, it examines the intergenerational claims of Indigenous communities and the extraterritorial claims of colonial and neocolonial subjects. The broad aim of this effort is to consider how centering the imperial roots of our contemporary nation-state system transforms our understanding and justifications of territorial sovereignty.

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.

This review essay surveys the contributions of the new edited volume African American Political Thought: A Collected History. The thinker-based approach to the study of African American political thought advanced in the volume highlights the ways in which thinkers reformulate the central political questions of the intellectual tradition and constitute the canon through the citation and invocation of earlier figures. It also draws attention to the rhetorical, strategic, and tactical dimensions of their political thought. The volume sets a new standard (...) for study of African American political thought and makes a persuasive case for the tradition’s important contributions to political theory broadly. However, by tying its significance too closely to its interventions within American political thought, the volume inadvertently minimizes the global resonances of African American political thought.

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)

The knowledge extraction from data with noise or outliers is a complex problem in the data mining area. Normally, it is not easy to eliminate those problematic instances. To obtain information from this type of data, robust classifiers are the best option to use. One of them is the application of bagging scheme on weak single classifiers. The Credal C4.5 model is a new classification tree procedure based on the classical C4.5 algorithm and imprecise probabilities. It represents a type of (...) the so-calledcredal trees. It has been proven that CC4.5 is more robust to noise than C4.5 method and even than other previous credal tree models. In this paper, the performance of the CC4.5 model in bagging schemes on noisy domains is shown. An experimental study on data sets with added noise is carried out in order to compare results where bagging schemes are applied on credal trees and C4.5 procedure. As a benchmark point, the known Random Forest classification method is also used. It will be shown that the bagging ensemble using pruned credal trees outperforms the successful bagging C4.5 and RF when data sets with medium-to-high noise level are classified. (shrink)
