La fenomenología de la razón escudriña todos los procesos racionales que intervienen en la aprehensión del objeto real y de su constitución, y las consiguientes relaciones noético-noemáticas. Sólo la razón pura colegida, primero como fuerza que depura los procesos de la evidencia y las posiciones del sujeto, y sólo la razón entendida también como proceso que ratifica la verificabilidad del darse el objeto y de todos los demás procesos y relaciones, se revela como la única instancia posible capaz de asegurar (...) la validez del conocimiento y del objeto del conocimiento. Por otro lado, la razón juega un papel decisivo en lo que respecta al sujeto de razón. Ésta es la nota constitutiva y respectiva del ser humano, el poder que lo separa del entramado de facticidades y contingencias de las que se compone la realidad, de suerte que éste no es un factum más entre todas las objetividades, tal como postulan la psicología y las ciencias naturales. El hombre es un ser mundano, está efectivamente en el mundo. Ahora bien, “su ser en” y “su estar en” son modificados por el poder de la razón. Su modo de ser mundano es serlo racionalmente. Únicamente de este modo el Umwelt deviene Lebenswelt.The phenomenology of reason inspects all rational processes involved in the apprehension of real object and its constitution, and the respective noetic-noematic relationships. Only the pure reason comprehended, first of all, as a strength which purifies the mentioned processes, the evidence and the subject positions. Secondly the reason, also comprehended as a process which confirms the object verificability which gives itself and the other processes and relationships, appears as the only possible power, which is able to guarantee the validity of the knowledge, and so the object of knowledge. On the other hand, the reason plays a very important role in the subject of the reason. This is the constitutive and respective note of the human being, the power that separates it from the labyrinth of facts and contingencies which makes up reality, so that this isn’t a fact among all objectivities, as postulated by psychology and natural sciences. The human being is a worldly being; he is really in the world. Now then, “his being-in” and “his staying-in” are modified by the strength of the reason. His way of being worldly is being rationaly. Only in this way the “Umwelt” becomes “Lebenswelt”. (shrink)

A new Arrovian impossibility is obtained without invoking independence of irrelevant alternatives type assumptions. The new conditions leading to the impossibility are based on the concept of power of enforcement, and specify how this power can (see A3) or cannot be expanded (see A1, A2 and A4).

The relationship between extensive and normal form analyses in non-cooperative game theory seems to be dominated, at least traditionally, by the so-called ‘sufficiency of the normal form principle’, according to which all that is necessary to analyse and ‘solve’ an extensive game is already in its normal form representation. The traditional defence of the sufficiency principle, that Myerson (1991, p. 50) attributes to von Neumann and Morgenstern, holds that, with respect to extensive games, it can be assumed without loss of (...) generality, that players formulate simultaneously and independently their strategic plans at the beginning of the game – a situation which, it is claimed, is exactly described by the normal representation of an extensive game.

It is shown that the axioms Cubitt and Sugden (1994; Economic J. 104: 798) impose on a theory of rationally justifiable play (TRJP) do not prevent the possibility that two players necessarily disagree concerning the probability they ascribe to the choice of a third player. This appears to indicate that those axioms are not sufficient for defining a `reasonable' TRJP. In addition, for the case in which a player's beliefs are statistically independent, conditions for a TRJP are suggested under which (...) the existence of a quasi-strict equilibrium is sufficient, but the existence of a consistent n-pair is not, for defining a TRJP meeting those requirements.

When preferences are defined over two alternatives and societies are variable, the group formed by the relative majority rule, the unanimity rule, the dictatorial rules, and the strongly dictatorial rules is characterized in terms of five axioms: unanimity, reducibility, substitutability, exchangeability, and parity. This result is used to provide characterizations of each of these rules by postulating separating axioms, that is, an axiom and its negation. Such axioms identify traits specifically differentiating a type of rule from the other types. For (...) instance, majority differs from strong dictatorship in the existence of a society for which collective indifference should be a less likely outcome than the strict preference of one alternative over the other. As a second example, the difference between majority and strong dictatorship can be traced back to the requirement that the likelihood of collective indifference diminishes with the size of society.

Two justifications of backward induction (BI) in generic perfect information games are formulated using Bonanno's (1992; Theory and Decision 33, 153) belief systems. The first justification concerns the BI strategy profile and is based on selecting a set of rational belief systems from which players have to choose their belief functions. The second justification concerns the BI path of play and is based on a sequential deletion of nodes that are inconsistent with the choice of rational belief functions.

Antonio Quesada (Public Choice 130:395–400, 2007) argues that a dictator has no more than two to three times the ‘average power’ of a non-dictatorial voter. If Quesada is correct, then his argument has major consequences for social choice theory; for instance, it warrants reconsidering the significance of Arrow’s Theorem. If Quesada is incorrect, however, then his position is dangerously misleading. This paper argues that Quesada is wrong. His argument depends on his own formal account of (...) power, an account that is implausible because it disregards a basic insight common to the standard characterisations of voting power: the idea that one has power over an outcome to the extent that one is able to change that outcome. Claims about power have a counterfactual component; to assert that an individual actually has determined an outcome is also to make an assertion about what would have been the case had that individual acted differently. We can employ David Lewis’s influential account of counterfactuals to show, contra Quesada, that in a dictatorship, nondictatorial individuals and groups cannot possibly determine a social preference. In short, Quesada is fundamentally mistaken about power, and thus also about the distribution of power in a dictatorship. (shrink)

Classical epistemic logic describes implicit knowledge of agents about facts and knowledge of other agents based on semantic information. The latter is produced by acts of observation or communication that are described well by dynamic epistemic logics. What these logics do not describe, however, is how significant information is also produced by acts of inference— and key axioms of the system merely postulate "deductive closure". In this paper, we take the view that all information is produced by acts, and hence (...) we also need a dynamic logic of inference steps showing what effort on the part of the agent makes a conclusion explicit knowledge. Strong omniscience properties of agents should be seen not as static idealizations, but as the result of dynamic processes that agents engage in. This raises two questions: (a) how to define suitable information states of agents and matching notions of explicit knowledge, (b) how to define natural processes over these states that generate new explicit knowledge. To this end, we use a static base from the existing awareness literature, extending it into a dynamic system that includes traditional acts of observation, but also adding and dropping formulas from the current ' awareness' set. We give a completeness theorem, and we show how this dynamics updates explicit knowledge. Then we extend our approach to multi-agent scenarios where awareness changes may happen privately. Finally, we mention further directions and related approaches. Our contribution can be seen as a ' dynamification' of existing awareness logics. (shrink)

Epistemic logic with its possible worlds semantic model is a powerful framework that allows us to represent an agent’s information not only about propositional facts, but also about her own information. Nevertheless, agents represented in this framework are logically omniscient: their information is closed under logical consequence. This property, useful in some applications, is an unrealistic idealisation in some others. Many proposals to solve this problem focus on weakening the properties of the agent’s information, but some authors have argued that (...) solutions of this kind are not completely adequate because they do not look at the heart of the matter: the actions that allow the agent to reach such omniscient state. Recent works have explored how acts of observation, inference, consideration and forgetting affect an agent’s implicit and explicit knowledge; the present work focuses on acts that affect an agent’s implicit and explicit beliefs. It starts by proposing a framework in which these two notions can be represented, and then it looks into their dynamics, first by reviewing the existing notion of belief revision, and then by introducing a rich framework for representing diverse forms of inference that involve both knowledge and beliefs.

Fazer a genealogia do poder nunca foi o propósito claro de Foucault. No entanto, a questão do poder foi tema recorrente em suas investigações a ponto de estudiosos do trabalho do filósofo sugerirem uma divisão e organização de seu trabalho a partir de três eixos teóricos. Dentro dessa perspectiva, a analítica do poder marcaria a trajetória filosófica de Foucault na década de 1970. De fato, até 1994, ano de publicação do conjunto de textos, entrevistas e conferências de Foucault no Dits (...) et écrits, a questão da analítica do poder era majoritariamente conhecida a partir de livros como Surveiller et punir e Histoire de la sexualité I: la volonté de savoir. Com o início da publicação dos cursos no Collège de France a partir de 1997 as interpretações a respeito da analítica do poder sofrem um alargamento. Mas é somente em 2015 que a totalidade dos cursos de Foucault no Collège de France foram publicados, abrindo um importante caminho para a investigação a respeito das primeiras reflexões a respeito do poder. No presente artigo procuramos mostrar como os primeiros passos da analítica do poder de Michel Foucault se dá a partir de um contexto gauchiste ainda configurado em termos de dinástica do saber. Nesse sentido, procuramos mostrar como o período da dinástica corresponde a um esboço teórico, tentativas primeiras de conceituação do poder, marcadamente desenvolvido em contraposição com o marxismo. Essa contraposição se dá sobretudo na recusa tanto do esquema marxista de infra-superestrutura, quanto do modelo contratualista de sociedade estatal. (shrink)

We look at two fundamental logical processes, often intertwined in planning and problem solving: inference and update. Inference is an internal process with which we uncover what is implicit in the information we already have. Update, on the other hand, is produced by external communication, usually in the form of announcements and in general in the form of observations, giving us information that might not have been available (even implicitly) before. Both processes have received attention from the logic community, usually (...) separately. In this work, we develop a logical language that allows us to describe them together. We present syntax, semantics and a complete axiom system; we discuss similarities and differences with other approaches and mention how the work can be extended. (shrink)

This article intends to analyze the implications of a hypothesis that extends Foucault's analysis of neoliberalism from its effects on modern democracy. For this purpose, Wendy Brown's recent work examines how neoliberal rationality affects democracy, transforms its imaginary and even its main subject, namely the demos. Brown points to two problems of the "neoliberalism's stealth revolution," namely that the neoliberal rationality transforms and undoes democracy by directly affecting its fundamental principle of popular sovereignty. Such transformation is made from the change (...) produced in the democratic imaginary and, mainly, from the transformation of the economic subject from a subject of interest to human capital, as well as the political subject, relegated to the background. From this first problem, we examine how they happen and what are the consequences of changing the democratic imaginary and its central political subject. The second problem pointed out by Brown deals with the interference of neoliberal reason in sovereign autonomy. The second part of this article seeks, therefore, to analyze the relationship between the sovereignty of the nation-state and the notion of popular sovereignty from the problem of the expansion of capital and the vulnerability of the frontiers and territory where citizenship is exercised.

François Mauriac desarrolló fundamentalmente su producción literaria en la primera mitad del siglo pasado, un periodo marcado por las dos Guerras Mundiales en una Francia en creciente proceso de secularización. Así las cosas, con motivo del cincuenta aniversario de su fallecimiento la pretensión de este trabajo es hacer emerger la figura de Mauriac como apologeta que, desde el ámbito literario, defendió algunos de los principales postulados católicos cuestionados por el alma moderna. En efecto, el premio Nobel de literatura pertenece a (...) esa constelación de autores católicos que, profundizando en las raíces del Cristianismo, intentan dar una salida a la crisis de la Modernidad, cimentada fundamentalmente en el positivismo y el materialismo. De hecho, veremos cómo plantea el problema del mal en el mundo y la solución al mismo desde el ámbito de la caridad por medio de mártires inmolados. Asimismo, asistiremos a la crítica sistemática del novelista francés contra el antitestimonio cristiano o contra el fariseísmo religioso como elementos clave de su pedagogía apologética. (shrink)

INCONTINENCE, HONOURING SUNK COSTS AND RATIONALITY According to a basic principle of rationality, the decision to engage in a course of action should be determined solely by the analysis of its consequences. Thus, considerations associated with previous use of resources should have no bearing on an agent’s decision-making process. Frequently, however, agents persist carrying on an activity they themselves judge to be nonoptimal under the circumstances because they have already allocated resources to that activity. When this is the case, agents (...) are said to be honouring sunk costs. Honouring sunk costs is thus typically viewed as irrational economic behaviour. Two striking findings of the psychological literature on the sunk cost effect are that it is, in general, not lessened by having taken previously courses in economics, and that agents who did take such courses and that do honour sunk costs seem to be frequently aware of a cognitive dissonance in their behaviour. Davidson’s account of the possibility conditions of incontinent action renders continent action materially unfeasible. The very idea of incontinent action becomes thus a hollow one. I’ll present an alternative description of these possibility conditions that renders continent action materially feasible, and both, continent and incontinent action, cognitively plausible. In a nutshell, my proposal rests upon the drawing of an essential cognitive contrast between explicit processes of deliberative reasoning and lower level heuristic procedures. I conclude the paper arguing that my redescription of incontinent action accounts for the above mentioned cognitive dissonance effect better than the alternatives and that viewing at least an important subset of behaviours of honouring sunk costs as incontinent actions will enable us to consider them as peculiar manifestations of a more general and meaningful pattern in human behaviour.

Philosophy affected the birth of Latin America in two ways. First it inspired the famous men who started the independence movements, which led to the definitive liberation from the Spanish yoke. Once the revolution was over, philosophy influenced the development of the legal and political systems that were created to organize the life of the new states.

This work proposes an understanding of deductive, default and abductive reasoning as different instances of the same phenomenon: epistemic dynamics. It discusses the main intuitions behind each one of these reasoning processes, and suggest how they can be understood as different epistemic actions that modify an agent’s knowledge and/or beliefs in a different way, making formal the discussion with the use of the dynamic epistemic logic framework. The ideas in this paper put the studied processes under the same umbrella, thus (...) highlighting their relationship and allowing a better understanding of how they interact together. (shrink)

Antonio Negri wrote the two essays that comprise Time for Revolution while serving a prison sentence for alleged involvement with radical left-wing groups. Although the essays were written two decades apart, their concerns are the same: is there a place for resistance in a society utterly subsumed by capitalism? In the wake of the global crisis of capitalism heralded by the 2008 crash, the question has never been more relevant and Negri remains an insightful and passionate guide to any (...) attempt to answer it.

In the valley of the Trujala, Hornos and Guadalimar rivers in the Sierra de Segura, northeast of the province of Jaén, is an articulated system of preserved Andalusi structures that configure a landscape. To orient in a landscape, one needs a map that accurately represents the elements involved in its formation. The objective of this work is to reveal these points and to draw a chart that serves to understand and read into the palimpsest of the landscape. To achieve this, (...) an intensive prospecting of the territory is carried out to document the existing remains and an evaluation model based on Geographic Information Systems is elaborated. This process allowed for quantifying variables, obtaining statistically relevant data and classifying the information obtained in places where there is some Andalusi preexistence. The results supply useful parameters in the analytical reading of the landscape, provide quantitative knowledge about factors that connect the sites, and allow for the determination of settlement patterns. The results also reveal the mode of occupation in a territory -the ancientʿamal Šaqūra- as a reflection of the Andalusi organization in the rural world and the anthropic role that these settlements, which are associated with structures built of rammed-earth during the 12th century, have had in the landscape’s configuration.

As a new type of epistemic logics, the logics of knowing how capture the high-level epistemic reasoning about the knowledge of various plans to achieve certain goals. Existing work on these logics focuses on axiomatizations; this paper makes the first study of their model theoretical properties. It does so by introducing suitable notions of bisimulation for a family of five knowing how logics based on different notions of plans. As an application, we study and compare the expressive power of these (...) logics. (shrink)

Marr’s celebrated contribution to cognitive science (Marr 1982, chap. 1) was the introduction of (at least) three levels of description/explanation. However, most contemporary research has relegated the distinction between levels to a rather dispensable remark. Ignoring such an important contribution comes at a price, or so we shall argue. In the present paper, first we review Marr’s main points and motivations regarding levels of explanation. Second, we examine two cases in which the distinction between levels has been neglected when considering (...) the structure of mental representations: Cummins et al.’s distinction between structural representation and encodings (Cummins in Journal of Philosophy, 93(12):591–614, 1996; Cummins et al. in Journal of Philosophical Research, 30:405–408, 2001) and Fodor’s account of iconic representation (Fodor 2008). These two cases illustrate the kind of problems in which researchers can find themselves if they overlook distinctions between levels and how easily these problems can be solved when levels are carefully examined. The analysis of these cases allows us to conclude that researchers in the cognitive sciences are well advised to avoid risks of confusion by respecting Marr’s old lesson. (shrink)

Internal misconduct is a universal problem in prisons and affects the maintenance of social order. Consequently, correctional institutions often develop rehabilitation programs to reduce the likelihood of inmates committing internal offenses and criminal recidivism after release. Therefore, it is necessary to identify the profile of each offender, both for the appropriate indication of a rehabilitation program and the level of internal security to which he must be submitted. In this context, this work aims to discover the most significant characteristics in (...) predicting inmate misconduct from ML methods and the SHAP approach. A database produced in 2004 through the Survey of Inmates in State and Federal Correctional Facilities in the United States of America was used, which provides nationally representative data on prisoners from state and federal facilities. The predictive model based on Random Forest performed the best, thus, we applied the SHAP to it. Overall, the results showed that features related to victimization, type of crime committed, age and age at first arrest, history of association with criminal groups, education, and drug and alcohol use are most relevant in predicting internal misconduct. Thus, it is expected to contribute to the prior classification of an inmate on time, to use programs and practices that aim to improve the lives of offenders, their reintegration into society, and consequently, the reduction of criminal recidivism.
