En este artículo discutimos la tesis de Jc Beall según la cual no hay negación lógica. Evaluamos la solidez del argumento con el que defiende su tesis y presentamos dos razones para rechazar una de sus premisas: que la negación tiene que ser excluyente o exhaustiva. La primera razón involucra una presentación alternativa de las reglas de la negación en sistemas de secuentes diferentes al que Beall presupone. La segunda razón establece que la negación no tiene que ser excluyente o (...) exhaustiva. (shrink)

Seen from the point of view of evaluation conditions, a usual way to obtain a connexive logic is to take a well-known negation, for example, Boolean negation or de Morgan negation, and then assign special properties to the conditional to validate Aristotle’s and Boethius’ Theses. Nonetheless, another theoretical possibility is to have the extensional or the material conditional and then assign special properties to the negation to validate the theses. In this paper we examine that possibility, not sufficiently explored in (...) the connexive literature yet.We offer a characterization of connexive negation disentangled from the cancellation account of negation, a previous attempt to define connexivity on top of a distinctive negation. We also discuss an ancient view on connexive logics, according to which a valid implication is one where the negation of the consequent is incompatible with the antecedent, and discuss the role of our idea of connexive negation for this kind of view.

In this paper we present a characterization of hyper-connexivity by means of a relating semantics for Boolean connexive logics. We also show that the minimal Boolean connexive logic is Abelardian, strongly consistent, Kapsner strong and antiparadox. We give an example showing that the minimal Boolean connexive logic is not simplificative. This shows that the minimal Boolean connexive logic is not totally connexive.

In this paper I explore whether three different approaches to connexivity – namely, Lewis and Langford’s, Wansing’s and Egré and Politzer’s – can be non-trivially related. Lewis and Langford’s approach consists of the definition of the conditional in terms of consistency via the definition of possibility in terms of consistency and Lewis’ definition of the (strict) conditional in terms of possibility; Wansing’s approach is based on his definition of the falsity condition for the conditional as “if A is true then (...) B is false”; Egré and Politzer’s approach relies on the modalization of the falsity condition for the conditional in its conditional form (A→◇~B). With this background in mind, I build upon Estrada-González’s work relating connexivism and possibilism, the thesis according to which everything is possible. Estrada-González’s work relates Lewis and Langford’s connexive approach with Nelson’s idea that every proposition is self-consistent. He does so using a fragment of LP augmented with a special conditional. This relation has resulted in the study and postulation of several truth-functional modalities, some of which have already been discussed elsewhere. I employ several truth-functional modalities to evaluate Egré and Politzer’s falsity conditions for the conditional. I show that in using Béziau’s truth-functional modality ◇B, definable in Estrada-González’s framework, one can retain in a single framework the three different approaches. More specifically, distinguishing the notion of logical equivalence from the notion of interderivability and these two from the notion of coimplication, it is possible to relate ~(A→B) and (A→◇~B) as interderivable schemas and in a valid biconditional. I also show some consequences of this for Béziau’s negative appraisal of three-valued truthfunctional modalities. (shrink)

O artigo trata das reformas educacionais apresentadas pelos organismos internacionais às nações periféricas, na perspectiva de um diálogo histórico-filosófico sobre as crises da educação nesse período de globalização. Privilegia o estudo teórico-bibliográfico de caráter analítico-exploratório, orientando-se pelo horizonte metodológico do materialismo histórico-dialético. Tem por objetivo compreender as implicações das crises do capital nas reformas educacionais dos países periféricos. No campo da educação, conclui-se que essas reformas estão em sintonia com as medidas neoliberais que visam fomentar uma mão-de-obra flexível e precarizada (...) para o mercado de trabalho, ao mesmo tempo em que buscam manter o controle socioeconômico e ideológico da classe trabalhadora.

The aim of this work is to present the thesis “On the Ontogenetic Evolution of the Human Embryo in its Relations with Phylogenesis,” by Affonso Regulo de Oliveira Fausto, published in Brazil in 1890. To our knowledge, it was one of the first Brazilian academic works focused specifically on evolution. It was also the first doctoral thesis that addressed the topic of recapitulation in order to analyze what was then called the progressive evolution of the human species in tandem with (...) the embryological development of the individuals that would constitute the Brazilian “type.” In the present work, we analyze the author’s thesis in relation to its sources, concepts, as well as the country’s political context at the time of its publication. Fausto’s text, in which he explicitly recognized the influence of Ernst Haeckel’s recapitulation theory, represents a window to understand better a concept of nation based on science and on the idea of inexorable progress that was accepted in Brazil at the end of the nineteenth century.

A predominância dos temas literários e fenomenológicos nos textos sartrianos dos anos 1930 já chamou atenção de vários especialistas e comentadores da obra do autor. É notável, entretanto, como os exames dos textos dessa época contentam-se, no mais das vezes, em apontar o paralelismo ou a contemporaneidade entre fenomenologia e literatura ali presente, sem realçar a fundamentação que uma parece conferir à outra e que constitui uma das questões mais interessantes que a filosofia sartriana levanta. Há que se incluir, na (...) verdade, a estética literária de Sartre na compreensão de suas teses fenomenológicas; teses estas que, por outro lado, fornecem o solo filosófico da literatura sartriana, em termos tanto de autoria quanto de crítica. O propósito deste artigo é demonstrar, assim, uma dependência ou, se quisermos, implicação mútua entre literatura e fenomenologia não apenas central em relação àquele período da produção de Sartre como, também, determinante para seus projetos teóricos e ficcionais ulteriores.

Drawing on the self-determination framework, the study examined the effect of coaches’ autonomy support on the leisure experience of young male football players. Specifically, a model was tested analyzing the long-term predictive power of the players’ perception of coach-autonomy support at the beginning of the season on the subjective vitality of young football players at the end of the season through needs satisfaction and intrinsic motivation. Moreover, we tested whether the effects of coach-autonomy support on the aforementioned variables (needs satisfaction, (...) intrinsic motivation, and subjective vitality) at the end of the season remained at the beginning of the following season. Because the coach in the second season was not the same one as in the first season, the perception of coach-autonomy support at the beginning of the second season was used as a control variable. Three hundred and sixty football players (M age = 12.60 years; SD = 0.52) completed a questionnaire on the variables of interest at the beginning of the first season (T1), at the end of the first season (T2), and at the beginning of the second season (T3). The results of the path analyses showed that player’ perceptions of coach autonomy support at the beginning of the season (T1) positively predicted needs satisfaction at the end of the first season (T2), which in turn predicted intrinsic motivation at the end of the first season (T2). Additionally, intrinsic motivation significantly and positively predicted subjective vitality at the end of the first season (T2). Finally, needs satisfaction, intrinsic motivation, and subjective vitality at the end of the second season (T2) positively predicted these same variables at the beginning of the second season (T3). Results emphasized the importance of the autonomy support offered by the coach in promoting the quality of young people’s leisure experience playing football and its benefits for their well-being.

Traditionally, research focused on determining the causes of employee pay satisfaction has investigated the influence of job-related inputs, both extrinsic and intrinsic to the job itself. Together with these inputs, pay-related fairness issues have played an important role in explaining the phenomenon. However, few studies consider the factors linked to fairness issues, such as ethical leadership. Because ethical leadership necessarily entails the concept of fairness, it seemingly should have a positive effect. Furthermore, because the presence of supervisor ethical leadership (SEL) (...) offers strong chances for employees to achieve moral accomplishments and excel in the practice of their jobs, SEL should enhance the effects of intrinsic job inputs. Whereas high job motivating potential (JMP) makes it easier for employees be self-actualized, moral fulfillment is necessary for them to obtain authentic self-actualization at work and minimize the impact of pay deficiencies. Along with SEL, JMP should be shaped to increase positive experiences of job meaningfulness, responsibility for job outcomes, and knowledge of results at work, which can lead to enjoyment in doing the job in itself, not just for compensation-related motives. Hierarchical regression analysis with a sample of 151 employees in a diverse set of Spanish organizations supports the direct effects of JMP and SEL and shows that higher levels of SEL increase the positive effects of JMP on pay satisfaction. The practical implications of these findings and further research directions conclude this article. (shrink)

Este trabajo estudia el pensamiento teológico y filosófico de Francisco Suárez sobre la libertad. El problema de la Concordia entre gracia y libertad, suprime el concepto de naturaleza como quicio del pensamiento filosófico cristiano. La libertad se sitúa como causa metafísica formal en Suárez, no como fundamento a la manera moderna de un Yo afincado en sus solas fuerzas, sino como principio heurístico y creador de un ser lleno de posibilidades cuya afirmación: “soy libre”, sintetiza la filosofía suareciana, y (...) hace inteligibles las realidades dadas por la experiencia concreta para obtener una comprensión superior.Palabras llave: Francisco Suárez; teología neoescolástica; filosofía neoescolástica.This work studies Francisco Suárez’s theological and philosophical thought about freedom. The problem of agreement between grace and freedom suppresses the concept of nature as physis and its ethiology, as a referential shelf for Christian philosophical thought. In Suárez, freedom is placed as a formal metaphysical cause, not as a foundation in the modern manner of an “I” based on its sole forces, but as heuristic principle that creates a being full of possibilities, whose statement: “I am free”, synthesizes Suárez’s philosophy and makes intelligible the realities given by concrete experience in order to obtain a superior understanding.Palabras llave: Francisco Suárez; theology; liberty.

As stated by previous researchers, in an increasingly competitive environment, organizations need to develop successful innovations to compete and survive in the long term. Furthermore, sustainability and social issues are gaining increasing importance, to the extent that they are now a matter of high concern for firms and for society. Therefore, organizations cannot improve their results at any price and must be responsible for the consequences of their activities, including innovation. In these conditions, a growing demand for new leadership styles (...) and behaviors arises to face this complex context. Stewardship is a leadership behavior that shows great concern for the impact of the organization’s activity on society. A quantitative study has been conducted with the purpose of providing empirical evidence of the relationship between leaders’ stewardship behavior and innovation success, using radical innovation as an explanatory variable. To confirm the hypotheses, structural equations were used on a dataset from a sample of 300 questionnaires from Spanish companies. The study empirically validates the proposed conceptual model. Results show how radical innovation fully mediates the relationship between leaders’ stewardship behavior and innovation success. (shrink)

BackgroundFor a long time, in sports, researchers have tried to understand an expert by comparing them with novices, raising the doubts if the visual search characteristics distinguish experts from novices. Therefore, the aim of the present study was to review and conduct a meta-analysis to evaluate the differences in visual search behavior between experts and novices in team sports athletes.MethodsThis systematic review with meta-analysis followed the PRISMA 2020 and Cochrane's guidelines. Healthy team athletes were included, which engaged in regular practice, (...) from any sex or competitive level, specifically classified a priori as expert or novice in the original research. We considered only research published in peer-reviewed journals, with no limitations regarding date or language. It was considered healthy team sport athletes engaged in regular practice. The scenarios could be in situ or film-based. The databases of EBSCO, PubMed, Scopus, SPORTDiscus, and Web of Science were used to perform the searches. The risk of bias was calculated through the RoBANS tool.ResultsFrom a total of 6,257 records, of which 985 were duplicates, titles and abstracts of 5,272 were screened, and 45 required full-text analysis. Of those, 23 were excluded due to not fulfilling the eligibility criteria regarding participants. In the end, 22 studies were selected, however, as two studies were part of the same trial and were analyzed conjointly.DiscussionExperts showed to be older and with more years of practice. The ability to distinguish experts from novices was not so clear regarding the variables analyzed. This could be due to the strategies chosen in each study, which were specific to each scenario, and when grouping all together, it was lost information within non-representative averages. The distinction between experts and novices was not clear, showing a lot of heterogeneity in the included studies. The expert classification itself may have been the conditioning aspect for these results, retaining the doubt and the need for more studies in the field.Systematic review registrationThe protocol was pre-registered in OSF.

O artigo apresenta uma pesquisa qualitativa que relata a organização espacial das fazendas aquícolas no litoral central de Santa Catarina, nas comunidades da Praia de Fora e Enseada de Brito, as quais se encontram no município de Palhoça, pertencentes ao Aglomerado Urbano de Florianópolis. As características de ocupação urbana nas localidades supracitadas remontam ao século XVIII, mantendo as atividades econômicas extrativistas e rurais até a segunda metade do século XX. A partir da década de 1960/1970 verificou-se acelerado processo de construção (...) de casas de veraneio, sobrepujado por uma intensa urbanização com moradores fixos por causa do calçamento da via principal em 2010. A legalização das fazendas marinhas ocorreu nesta mesma época, como parte do “Plano Nacional de Desenvolvimento da Maricultura”, nos estados litorâneos brasileiros com aptidão ao cultivo nas comunidades envolvidas, apesar dos conflitos socioambientais. O município de Palhoça detém a maior produção de mexilhões em Santa Catarina. O marisco é um alimento popular no litoral catarinense e também uma iguaria na gastronomia internacional. A maior ameaça ao setor são os efluentes urbanos e os seus impactos ambientais. A falta de uma associação de produtores, bem como de um planejamento voltado à ocupação territorial de modo controlado e racional, tomando como fim a preservação do ecossistema de interesse, afeta a continuidade e o desenvolvimento econômico da atividade.

El objetivo del presente estudio es analizar algunos aspectos vinculados a la interpretación de la ley humana y su causa final en el pensamiento del teólogo, f ilósofo y jurista Español Francisco Suárez (1548-1617). En algunos autores resulta indudable su pertenencia a un modo de pensar determinado. Ello se observa, por mencionar algunos ejemplos, en los casos de Alberto Magno y Tomás de Aquino —identiicados con la edad media—. Por el contrario otros autores, aún medievales, desarrollaron doctrinas que se (...) constituyeron en preludio de elaboraciones posteriores modernas. Por este motivo tales figuras resultan fuertemente vinculadas a al- gunas corrientes de pensamiento modernas. Aquí puede mencionarse a Escoto, Ockham y Marsilio de Padua. Esta claridad recientemente señalada no se observa en relación a Francisco Suárez quien aparece como un autor controvertido y considerado de transición, por lo menos temporalmente, entre edad media y moderna. Las discusiones actuales en torno a Suárez se deben a la inexistencia de un cierto consenso respecto al lugar que le corresponde a su doctrina, especialmente filosófico-política, entre las concepciones que caracterizan a los períodos antiguo-medieval y moderno. Por estos motivos esta investigación persigue def inir la ubicación del pensamiento suareciano, en relación al tema propuesto, y de acuerdo a lo que nuestro autor expone en su Tratado de la Ley.

El autor realiza una lectura en clave perspectivista de la neurofenomenología, enfoque transdisciplinar y metodológico iniciado a mediados de los 90 por el neurobiólogo Francisco J. Varela desde el ámbito experimental de las ciencias de la mente. La originalidad del artículo reside en que estudia comparativamente el problemático entrecruce de la neurofenomenología de Varela con el perspectivismo científico de Ronald N. Giere, mostrándonos que la neurofenomenología no sólo lo antecedió cronológicamente, sino que fue mucho más radical al tener en (...) cuenta la la dimensión fenomenológica y trascendental de la experiencia vivida humana y al aplicarla en los protocolos de las neurociencias cognitivas. // The author makes a perspectivist reading of neurophenomenology, a transdisciplinary and methodological approach pioneered in the 90’s by the neurobiologist Francisco J.

Giere. In this way, the autor shows how neurophenomenology notonly came before Giere’s proposal but also how it was more radical in considering the phenomenological and transcendental human dimension and in trying an implementation in cognitive neuroscience protocols.

Francisco de Miranda (1750-1816), militar, viajero ilustrado, y, sobre todo, precursor de la independencia latinoamericana, ha sido objeto de numerosos estudios biográficos centrados fundamentalmente en su vida azarosa y aventurera. Sin embargo, su periplo intelectual ha sido investigado en un grado mucho menor, sobre todo en lo que se refiere a su meditación constitucional. El presente artículo tiene como fin, precisamente el de estudiar la relación de su pensamiento con la actuación política que le condujofinalmente a convertirse en Generalísimo (...) de la república de Venezuela en el año 1812, llegando a concentrar poderes excepcionales para hacer frente a la metrópoli española. De resultas de tal investigación puede concluirse que Miranda hizo una lectura de diversos autores ilustrados conocidos en Europa y el Nuevo Mundo, pero que también extrajo distintas reflexiones de su propia experiencia política por haber tomado parte en las dos grandes revoluciones del siglo XVIII.

Los Estados Unidos de América no emergieron como una auténtica nación con sólidas instituciones estatales hasta bien entrado el siglo XIX, pese a compartir una cultura común. La estructura conf igurada inicialmente para sostener su vínculo político fue el foedus o alianza entre Estados del Derecho de gentes, y el objetivo de este trabajo es precisar en qué medida influiría en la articulación constitucional de la joven república, desde su proclamación de la independencia hasta la Convención de Filadelf ia de (...) 1787. Para ello se examina la influencia de pensadores como Vattel, Montesquieu o Pufendorf en los colonos americanos y se expone el conflicto entre unos y otros Estados de la Unión. El resultado del estudio apunta a que la fórmula federativa que le permitió a la república ser reconocida por las naciones europeas le sirvió también para aplazar sus conflictos internos, y de modo muy especial el referente a la esclavitud, merced a una dinámica territorial de carácter expansivo.

Algebraic quantum field theory (AQFT) puts forward three ``causal axioms'' that aim to characterize the theory as one that implements relativistic causation: the spectrum condition, microcausality, and primitive causality. In this paper, I aim to show, in a minimally technical way, that none of them fully explains the notion of causation appropriate for AQFT because they only capture some of the desiderata for relativistic causation I state or because it is often unclear how each axiom implements its respective desideratum. After (...) this diagnostic, I will show that a fourth condition, local primitive causality (LPC), fully characterizes relativistic causation in the sense of fulfilling all the relevant desiderata. However, it only encompasses the virtues of the other axioms because it is implied by them, as I will show from a construction by Haag and Schroer (1962). Since the conjunction of the three causal axioms implies LPC and other important results in QFT that LPC does not imply, and since LPC helps clarify some of the shortcomings of the three axioms, I advocate for a holistic interpretation of how the axioms characterize the causal structure of AQFT against the strategy in the literature to rivalize the axioms and privilege one among them.

A questão sobre Deus em Aristóteles aparece na teoria sobre o primeiro motor imóvel, demonstrada no livro XII da Metafísica. Tudo o que se move é movido por outro. Entende Aristóteles que no universo há uma série indeterminada de motores e movidos. Todos os movimentos têm uma causa anterior. Mas, não é possível regredir ao infinito, pois todos e cada um sempre dependeriam de outro. Por esta razão, conclui o Estagirita que é necessário que exista um primeiro motor imóvel que (...) não seja movido por nenhum outro. Ora, se não existisse um primeiro motor absoluto, seria impossível o movimento gerado nos outros motores que compõem o universo. Neste estudo sobre a teoria aristotélica, que se tornou tradicional na teodiceia, apresentamos determinados passos da Metafísica com o auxílio de alguns comentadores sem, contudo, entrar em aporias importantes que o texto aristotélico vem suscitando entre os pesquisadores.

O objetivo é analisar algumas interpretações conexas que giram em torno da tensão entre duas concepções da díke em Édipo Rei. Como as tragédias ocupavam um papel privilegiado na pólis ateniense, pode-se dizer que as exibições e festividades trágicas eram uma verdadeira instituição política.

Tal tensão pode ser evidenciada na investigação promovida por Édipo que se manifesta em (...) duas formas de justiça, uma de origem divina e outra, humana. Para tanto, este texto, em um primeiro momento, descreve a relação entre tragédia e pólis; após essa introdução, assinala o conflito que se desenhava na democracia e que se reflete nas tragédias; por fim, examina a possível articulação racional entre a díke tradicional e sua contrapartida humana.

Como veremos, (...) sin embargo, sólo este segundo modelo es el que Aristóteles realmente le atribuye a Anaximandro.

Sexting has been defined as sending, receiving, or forwarding sexually explicit messages, images, or photos to others through digital platforms, and can assume more consensual or more abusive and violent forms. This study aims to explore the prevalence of abusive sexting in Portuguese adolescents and the psychological characteristics of sexting abusers in terms of emotional and behavioral problems, potential markers of psychopathy, childhood trauma and maltreatment, and different forms of aggression. A cross-sectional study was conducted with 4,281 participants, aged 12–20 (...) years, of whom 204 engaged in abusive sexting behaviors and 182 self-identified as being a non-consensual sexting victim. Abusive sexting was more common among boys and middle adolescents, and abusive sexting victims were more likely to be children of single-parent families. Engaging in abusive sexting and being a victim of abusive sexting were also related to behavioral and emotional problems, callousness, experiences of neglect and abuse in childhood, and various forms of aggression. Implications for future research and intervention are discussed. (shrink)

Durante el siglo IV a. C. los intelectuales griegos discutieron sobre los alcances y características de la labor filosófica, en un intento por delimitar esta práctica distinguiéndola de otras. En este artículo me centraré en el retrato del sofista como contracara del filósofo. Analizaré específicamente la respuesta platónica al ataque que Isócrates dirige contra todos los discípulos de Sócrates en Contra los sofistas y Encomio de Helena. Defenderé que la estrategia de Platón para eludir dicha crítica consistió en construir en (...) el Eutidemo y la quinta definición del Sofista un personaje que reúne los rasgos más censurados por Isócrates: el sofista erístico. Argumentaré que esta figura no remite a los sofistas del siglo V a. C., sino que tras ella se encuentran ocultos los representantes del grupo megárico, a quienes Platón habría colocado como los principales merecedores de la embestida isocrática. During the fourth century BC, Greek thinkers discussed about the limits and characteristics of philosophy in order to distinguish it from other practices. In this paper, I will focus on the portrait of sophists as diametrically opposed to philosophers. Specifically, I will discuss the platonic answer to the charge that Isocrates directed against all Socrates’ disciples in the treatises Against the Sophists and Encomium of Helen. I will defend that Plato’s strategy to avoid his critics was to develop, in the Euthydemus and the fifth definition of the Sophist, a character that combines the most significant attributes censured by Isocrates: the eristic sophist. I will argue that this figure does not refer to the Sophists of the fifth century BC., but to the Megaric group. They would have been those who, according to Plato, really deserved the Isocratic attack. (shrink)

Parmenides believed that he had found the most reliable way of theorizing about ultimate reality. While natural philosophers conceptualized phenomenal differences to explain cosmic change, Parmenides used the least meaningful but most versatile verb in Ancient Greek to engage in a purely intellectual exploration of reality – one that transcended synchronous and asynchronous differences. In this article I explain how the verb εἰμί was useful to Parmenides in his attempt to overcome natural philosophy. First, I argue that the Eleatic philosopher (...) regarded νοεῖν and εἶναι as equivalent because εἰμί-clauses enabled him to express arguably any conceivable content without providing significant additional meaning. I then show that Parmenides’ concept of being implies the present tense and the imperfective aspect but is grounded in the lexical content of the verb εἰμί, which entails no inherent temporal limits. This explains why ἔστι, ἐόν, and εἶναι could be used to indicate unbounded actuality, regardless of whether these forms represented lexical predicates or auxiliaries for predication. Finally, I maintain that the suitability of εἰμί for talking about all kinds of things without introducing temporal limits allowed Parmenides to avoid what he saw as two mistakes made by natural philosophers: identifying ultimate reality with something that cannot cover the full extent of thought and confusing actuality with present occurrence.

Truth is one of the main concepts of Philosophy, some even consider it the most important of all (W. Künne). This concept is also a foundation for other philosophical concepts. Some of them even depend intrinsically on it, such as the concepts of belief (to believe in something is to believe this something is true), knowledge (if you know something then that something is true), fact (facts are what make our statements true), existence (true reality is the external world that (...) exists) and modality (there are propositions that can be true in all possible worlds), among many others. Truth is also a crucial concept for other domains. Science is said to be the search for the truth of the Natural World and the good life is said to be the pursuit of the good (Aristotle). If one considers that the good and the just are objects of knowledge (R. Campbell), then, there could be no good or justice without truth, insofar as knowledge needs truth. Also, our confidence in the robustness of western political and social institutions has always rested on truth. Unfortunately, this basis, which is the foundation of trust and, therefore, of the robustness of our institutions, is being eroded by external forces, deniers and nihilists, by undermining the concept of Truth, endangering in that way the democratic model (H. Frankfurt). The troubled events we have recently experienced – the raise of populisms, conspiracy theories, pandemic skepticism, the conflict in Ukraine not only in the battleground but also in the info space – could, to some extent, make us question whether, in fact, there is still any theoretical interest in “truth”. As several authors have noted, it seems that today we live in a society of “post-truth” (A. Szakolczai) or “veritophobia” (A. Goldman), where lies are tolerated and facts ignored. Also, for this reason, understanding what truth is by reflecting on its nature and function, from the most sophisticated conceptual schemes to its most everyday uses, seems to be a philosophical task of the utmost importance. This is why the Revista Portuguesa de Filosofia has decided to dedicate this special issue to the subject of truth. (shrink)
