We respond to criticism of our paper “Paradox in Wave-Particle Duality for Non-Perturbative Measurements”. We disagree with Steuernagel’s derivation of the visibility of the Afshar experiment. To calculate the fringe visibility, Steuernagel utilizes two different experimental situations, i.e. the wire grid in the pattern minima and in the pattern maxima. In our assessment, this procedure cannot lead to the correct result for the complementarity properties of a wave-particle in one particular experimental set-up.

The expressivist account of knowledge attributions, while claiming that these attributions are nonfactual, also typically holds that they retain a factual component. This factual component involves the attribution of a belief. The aim of this work is to show that considerations analogous to those motivating an expressivist account of knowledge attributions can be applied to belief attributions. As a consequence, we claim that expressivists should not treat the so-called factual component as such. The phenomenon we focus on to claim that (...) belief attributions are non-factual is that of normative doxastic disagreement. We show through several examples that this kind of disagreement is analogous to that of the epistemic kind. The result will be a doxastic expressivism. Finally, we answer some objections that our doxastic expressivism could seem to face. (shrink)

Unfounded—conspiracy and health—beliefs about COVID-19 have accompanied the pandemic worldwide. Here, we examined cross-nationally the structure and correlates of these beliefs with an 8-item scale, using a multigroup confirmatory factor analysis. We obtained a two-factor model of unfounded (conspiracy and health) beliefs with good internal structure (average CFI = 0.98, RMSEA = 0.05, SRMR = 0.04), but a high correlation between the two factors (average latent factor correlation = 0.57). This model was replicable across 50 countries (total N = 13,579), (...) as evidenced by metric invariance between countries (CFI = 0.96, RMSEA = 0.06, SRMS = 0.07) as well as scalar invariance across genders (CFI = 0.98, RMSEA = 0.04, SRMS = 0.03) and educational levels (CFI = 0.98, RMSEA = 0.04, SRMS = 0.03). Also, lower levels of education, more fear of COVID-19, and more cynicism were weakly associated with stronger conspiracy and health beliefs. The study contributes to knowledge about the structure of unfounded beliefs, and reveals the potential relevance of affective (i.e., fear of COVID-19) and cognitive (i.e., cynicism) factors along with demographics, in endorsing such beliefs. In summary, we obtained cross-cultural evidence for the distinctiveness of unfounded conspiracy and health beliefs about COVID-19 in terms of their structure and correlates. (shrink)

Rejecting the Cut rule has been proposed as a strategy to avoid both the usual semantic paradoxes and the so-called v-Curry paradox. In this paper we consider if a Cut-free theory is capable of accurately representing its own notion of validity. We claim that the standard rules governing the validity predicate are too weak for this purpose and we show that although it is possible to strengthen these rules, the most obvious way of doing so brings with it a serious (...) problem: an internalized version of Cut can be proved for a Curry-like sentence. We also evaluate a number of possible ways of escaping this difficulty. (shrink)

The relationship between individuals and communities — all manner of communities, but especially the state — is a central preoccupation of property theory. Even though the relationship between individuals and community stands at the conceptual center of property theory, the theories of community underlying discussions of property are frequently left implicit. The dominant approaches to property in Anglophone scholarship, utilitarian and classical liberal theories, treat communities as agglomerations of individuals. Moreover, they eschew substantive accounts of justice, favoring what Charles Taylor (...) has called "procedural" conceptions. In this Article, we offer an ontological conception of community that views the individual and community as mutually dependent. In contrast with the two competing theories we describe, we favor a substantive conception of justice built around the notion of human flourishing. Although we are reluctant to embrace any particular label for our view, it is broadly Aristotelian in its framework. Once we have sketched the outlines of our theory, we will describe how our ontological theory might operate, using State v. Shack and a prominent South African property case as our central examples.

O intento deste ensaio é mostrar que o diálogo Sofista nos apresenta a concepção madura das Formas na filosofia de Platão. Essa concepção difere em vários aspectos importantes da concepção inicial das Formas presente nos chamados diálogos médios, em especial nos Livros V-VII da República. Para tanto, minha estratégia retórica e argumentativa consiste em contrastar a imagem da linha segmentada explicitamente proposta por Platão na República como símbolo dessa concepção inicial com a imagem da árvore das Formas enquanto imagem simbólica (...) da concepção madura. Embora não diretamente proposta por Platão, essa imagem clássica, derivada da Isagoge de Porfírio, remonta diretamente ao método de divisão operado no Sofista. Através do contraste entre essas duas imagens simbólicas, apresento inicialmente as diferenças entre as concepções das Formas inscritas na imagem da linha segmentada e a imagem da árvore das Formas. Em seguida, apresento duas diferenças fundamentais entre essas concepções. A primeira diz respeito a duas distintas imagens da dialética presentes na República e no Sofista. A segunda delas consiste no apagamento da diferença entre dianoia e nous fundamental na República, dando lugar à supremacia da dianoia no Sofista. (shrink)

This thesis consists in six articles and a comprehensive summary. • The pourpose of the summary is to introduce the AGM theory of belief change and to exemplify the diversity and significance of the research that has been inspired by the AGM article in the last 25 years. The research areas associated with AGM was divided in three parts: criticisms, where we discussed some of the more common criticisms of AGM. Extensions where the most common extensions and variations of AGM (...) are presented and applications where we provided an overview of applications and connections with other areas of research. • Article I elaborates on the connection between partial meet contractions [AGM85] and kernel contractions [Han94a] in belief change theory. Also both functions are equivalent in belief sets, there are notequivalent in belief bases. A way to define incision functions from selection functions and vice versa is presented. It is explained under which conditions there are exact correspondences between selection and incision functions so that the same contraction operations can be obtained by using either of them. • Article II proposes an axiomatic characterization for ensconcement-based contraction functions, belief base functions proposed byWilliams and relates this function with other kinds of base contraction functions. • Article III adapts the Fermé and Hansson model of Shielded Contraction [FH01] as well as Hansson et all Credibility-Limited Revision [HFCF01] for belief bases, to join two of the many variations of the AGM model [AGM85], i.e. those in which knowledge is represented through belief bases instead of logic theories, and those in which the object of the epistemic change does not get the priority over the existing information as it is the case in the AGM model. • Article IV introduces revision by comparison a refined method for changing beliefs by specifying constraints on the relative plausibility of propositions. Like the earlier belief revision models, the method proposed is a qualitative one, in the sense that no numbers are needed in order to specify the posterior plausibility of the new information. The method uses reference beliefs in order to determine the degree of entrenchment of the newly accepted piece of information. Two kinds of semantics for this idea are proposed and a logical characterization of the new model is given. • Article V focuses on the extension of AGM that allows change for a belief base by a set of sentences instead of a single sentence. In [FH94], Fuhrmann and Hansson presented an axiomatic for Multiple Contraction and a construction based on the AGM Partial Meet Contraction. This essay proposes for their model another way to construct functions: Multiple Kernel Contraction, that is a modification of Kernel Contraction,proposed by Hansson [Han94a] to construct classical AGM contractions and belief base contractions. • Article VI relates AGM model with the DFT model proposed by Carlos Alchourrón [Alc93]. Alchourrón devoted his last years to the analysis of the notion of defeasible conditionalization. His definition of the defeasible conditional is given in terms of strict implication operator and a modal operator f which is interpreted as a revision function at the language level. This essay points out that this underlying revision function is more general than AGM revision. In addition, a complete characterization of that more general kind of revision that permits to unify models of revision given by other authors is given. (shrink)

Achieving energy sovereignty is increasingly gaining prominence as a goal in energy politics. The aim of this paper is to provide a conceptual analysis of this principle from an ethics and social justice perspective. We rely on the literature on food sovereignty to identify through a comparative analysis the elements energy sovereignty will most likely demand and thereafter distinguish the unique constituencies of the energy sector. The idea of energy sovereignty embraces a series of values, among which we identified: (i) (...) accessibility, to allow access to everyone, (ii) empowerment and recognition, to develop and sustain capabilities to collaboratively produce solution-oriented energy system knowledge and effectively participate in governance, (iii) stewardship and sustainability, to be able to design and manage decentralised renewable systems in view of protecting the environment, (iv) self-sufficiency, to reduce the negative shocks of exploitative business practises, (v) resilience, to maintain production capacities while withstanding socioeconomic, political, environmental and climatic shocks, (vi) peace, to establish production systems that do not involve hostile relations, (vii) transparency and self-determination, to establish democratic decision-making mechanisms that give a voice to previously underrepresented groups and limit corporate takeover (viii) gender-justice, by acknowledging the contributions of women and eliminate barriers to their empowerment. With a conceptual framework of energy sovereignty, we present a rationale that draws on the key values to be considered when formulating policy solutions for the energy sector. (shrink)

Las Comunidades de Castilla, como movimiento social y político, pueden caracterizarse como una tentativa de renovación de la monarquía carolina como forma de gobierno. El creciente conocimiento sobre la circulación de ideas políticas que informaron el corpus doctrinal comunero permite precisar conceptual y terminológicamente un debate revisitado con frecuencia sobre la naturaleza revolucionaria o no de tal proceso. Acudir a los textos de los principales sustentadores teóricos de las Comunidades, tanto como a los documentos de sus reivindicaciones, y no solo (...) a una interpretación de síntesis ex post, contribuye a perfilar el alcance sobre sus pretensiones de reforma respecto a la forma del Estado o a la forma del gobierno, sobre la base de la participación y la igualdad. Apoyarse en las nociones de régimen político y sistema político a la luz de tales textos permite una mejor comprensión del movimiento como reformista más que como revolucionario. (shrink)

Las «metáforas», «analogías» o «alegorías» tienen un lugar bien ganado en la tradición filosófica. Han sido atacadas por dar lugar a una interpretación poco rigurosa de las nociones que describen, pues permite asociarles propiedades que originalmente no se había pensado (ni resulta deseable) que formen parte de su concepto. Sin embargo, a pesar del reclamo en favor de procedimientos estrictos de definición, el uso de una imagen apropiada suele ser el mejor modo de explicar esas cuestiones que cada siglo escapan (...) a la disección que el filo de las mejores definiciones pretendía darle. Tal es el caso de las ilustraciones usadas por Charles S. Peirce en sus artículos "Algunas consecuencias de cuatro incapacidades" y "Cómo esclarecer nuestras ideas" para dar cuenta del pensamiento. Primero veremos el papel que juegan estas imágenes en la argumentación conque Peirce establece dos principios importantes de su filosofía: el de que toda cognición se encuentra determinada por otras cogniciones previas, y el de que no tenemos ningún poder de introspección. Luego hallaremos que dos de las imágenes presentan cierta incompatibilidad en un aspecto especialmente relevante desde el punto de vista de lo que tratan de ilustrar. Para finalizar, consideraremos una explicación que sea consistente con los textos y que permita resolver la discrepancia, brindando una mejor comprensión conjunta de ambas ilustraciones . (shrink)

A Fenomenologia tem sido repensada nas últimas décadas a partir do trabalho de autoras feministas que têm promovido uma renovação das perspectivas fenomenológicas a partir de diferentes situacionalidades, atravessamentos e de um forte criticismo. O texto, como um ensaio, vislumbra tais possibilidades a partir de uma leitura do livro “50 Concepts for a Critical Phenomenology”, editado por Gail Weiss, Ann V. Murphy e Gayle Salamon. O objetivo é problematizar as potencialidades abertas para a Fenomenologia a partir de uma perspectiva Crítica (...) e Feminista. (shrink)

L'histoire de la réception littéraire de l'Utopie de Thomas More au Portugal a été une histoire d'omissions, de censures et de traductions différées qui met en évidence un défaut dans le système culturel portugais. En effet, il est quelque peu ironique qu'une œuvre aussi représentative de la littérature et de la pensée occidentale, historiquement associée à l'ouverture des horizons géographiques du monde, et qui attribue au personnage d'un marin lusitanien, Raphaël Hythlodée, la découverte d'un lieu idéal, n'a été traduite en (...) portugais que dans la seconde moitié du vingtième siècle. Cependant, la première décennie du vingt-et-unième siècle semble annoncer une fortune littéraire plus favorable à l'Utopie de More dans la langue portugaise: non seulement une édition du chef d'œuvre de More a finalement été traduite du latin, mais aussi deux romans ont été publiés en 2004, A lenda de Martim Regos, de Pedro Canais, et Rafael, de Manuel Alegre. Dans le cadre de leurs propres déroulements narratifs, les deux œuvres réaccentuent les traits complexes du personnage du marin portugais et découvreur de l'île idéale. La même réinvention du personnage de Raphaël avait déjà été tentée, en 1998, par José V. de Pina Martins dans son long récit dialogique Utopia III. Dans cet essai, je me concentrerai à la fois sur les sources documentaires liées à la culture portugaise qui sont à la base de l'Utopie de More et sur certains aspects pertinents de la réception du personnage de Raphaël Hythlodée dans les romans susmentionnés.

We introduce and consider the inner-model reflection principle, which asserts that whenever a statement \varphi(a) in the first-order language of set theory is true in the set-theoretic universe V, then it is also true in a proper inner model W \subset A. A stronger principle, the ground-model reflection principle, asserts that any such \varphi(a) true in V is also true in some non-trivial ground model of the universe with respect to set forcing. These principles each express a form of width (...) reflection in contrast to the usual height reflection of the Lévy–Montague reflection theorem. They are each equiconsistent with ZFC and indeed \Pi_2-conservative over ZFC, being forceable by class forcing while preserving any desired rank-initial segment of the universe. Furthermore, the inner-model reflection principle is a consequence of the existence of sufficient large cardinals, and lightface formulations of the reflection principles follow from the maximality principle MP and from the inner-model hypothesis IMH. We also consider some questions concerning the expressibility of the principles. (shrink)

El objeto de este trabajo es realizar un estudio iusfilosófico sobre la aparición de las Leyes (nómoi) personificadas de Atenas en el Critón de Platón. La prosopopeya de las Leyes resulta ser un aspecto central para poder comprender la obra, ya que éstas entablan un diálogo imaginario con Sócrates en el cual instalan diversos argumentos filosóficos para fundamentar la autoridad de la pólis. A los fines de identificar el valor argumentativo de este recurso en la obra, analizaré el significado del (...) nómos en la Atenas del siglo V a. C. y la naturaleza de las Leyes en el contexto general del diálogo. Se busca demostrar la importancia que tienen aquéllas para explicar la decisión de Sócrates de beber la cicuta. (shrink)

Apresento neste ensaio alguns argumentos em defesa de uma proposta de metafilosofia que fornece uma resposta abrangente, formal e metodológica à questão ‘como se faz filosofia?’, tomada como anterior e mais fundamental do que a questão tradicional ‘o que é filosofia?’. Essa proposta se materializa metodologicamente através das ideias de uma poética e uma dramaturgia do fazer filosófico. A poética do fazer filosófico tem a ver com uma reapropriação do trivium clássico na forma de um trivium filosófico, composto por uma (...) gramática, uma dialética e uma retórica filosóficas. A dramaturgia do fazer filosófico se associa à polissemia da noção de diálogo, entendido como encenação argumentativa. Em seguida, apresento uma breve genealogia da noção de theatrum philosophicum em sua relação com as configurações assumidas pela tópica do theatrum mundi no final do medievo e início da modernidade. Por fim, apresento como esta relação nos fornece uma via de acesso para explicitar a poética e a dramaturgia do fazer filosófico elaborada por Platão nos Livros V-VII da República, mostrando assim que minha proposta de metafilosofia é contemporânea, mas tem sua gênese neste texto clássico.

This paper presents and discusses an authentic landmark in the history of science, namely H. v. Foerster’s Cybernetics of Cybernetics, 1974. This is a book rarely known even by many specialists. This paper argues that von Foerster’s book constitutes a unique achievement in the history of science. A thorough presentation is introduced that brings a complete panorama of concepts, problems and approaches.

Animal data suggest that jet fuels such as JP-8 are associated with hearing deficits when combined with noise and that the effect is more pronounced than with noise exposure alone. Some studies suggest peripheral dysfunction while others suggest central auditory dysfunction. Human data are limited in this regard. The aim of this study was to investigate the possible chronic adverse effects of JP-8 combined with noise exposure on the peripheral and central auditory systems in humans. Fifty-seven participants who were current (...) personnel from the Royal Australian Air Force were selected. Based on their levels of exposure to jet fuels, participants were divided into three exposure groups. Groups were also categorised based on their noise exposure levels. All participants were evaluated by tympanometry, pure-tone audiometry, distortion product otoacoustic emissions, auditory brainstem response, words-in-noise, compressed speech, dichotic digit test, pitch pattern sequence test, duration pattern sequence test and adaptive test of temporal resolution. All auditory tests were carried out after the participants were away from the Air Force base for a minimum of two weeks, thus two weeks without jet fuel and noise exposure. Jet fuel exposure was significantly associated with hearing thresholds at 4 and 8 kHz; average hearing thresholds across frequencies in the better ear; DPOAEs at 2.8, 4 and 6 kHz; ABR wave V latency in the right ear; compressed speech and words-in-noise. Further analyses revealed that participants with low exposure level to jet fuels showed significantly better results for the aforementioned procedures than participants with moderate and high exposure levels. All results were controlled for the covariates of age and noise exposure levels. The results suggest that jet fuel exposure, when combined with noise exposure, has an adverse effect on audibility in humans. Taking all the test results into consideration, jet fuel exposure combined with noise exposure specifically seems to affect the peripheral hearing system in humans. (shrink)

In this article, we will present a number of technical results concerning Classical Logic, ST and related systems. Our main contribution consists in offering a novel identity criterion for logics in general and, therefore, for Classical Logic. In particular, we will firstly generalize the ST phenomenon, thereby obtaining a recursively defined hierarchy of strict-tolerant systems. Secondly, we will prove that the logics in this hierarchy are progressively more classical, although not entirely classical. We will claim that a logic is to (...) be identified with an infinite sequence of consequence relations holding between increasingly complex relata: formulae, inferences, metainferences, and so on. As a result, the present proposal allows not only to differentiate Classical Logic from ST, but also from other systems sharing with it their valid metainferences. Finally, we show how these results have interesting consequences for some topics in the philosophical logic literature, among them for the debate around Logical Pluralism. The reason being that the discussion concerning this topic is usually carried out employing a rivalry criterion for logics that will need to be modified in light of the present investigation, according to which two logics can be non-identical even if they share the same valid inferences.

The concept of _substructural logic_ was originally introduced in relation to limitations of Gentzen’s structural rules of Contraction, Weakening and Exchange. Recent years have witnessed the development of substructural logics also challenging the Tarskian properties of Reflexivity and Transitivity of logical consequence. In this introduction we explain this recent development and two aspects in which it leads to a reassessment of the bounds of classical logic. On the one hand, standard ways of defining the notion of logical consequence in classical (...) logic naturally induce substructural logics when admitting more than two truth values; on the other hand, these substructural logics give rise to hierarchies of _metainferences_ that can be used to approximate classical logic at different levels.
