This paper discuss the relations between the conception of freedom of press and the construction of a professional identity on journalism. As a departure point, we do bibliographical revision of the press freedom definition as it was initially elaborated by Illuminist philosophers. After that, we investigate how such concepts integrate journalists’ self- legitimating discourse and also how it participates on the construction of their identity.

Physiological responses in futsal have not been studied together with temporal information about the players’ stay on the court. The aim of this study was to compare heart rate and blood lactate concentration responses between 1-H and 2-H considering the time of permanency of the players on the court at each substitution in a futsal match. HR was recorded during entire match and [La−] was analyzed after each substitution of seven players. %HRmean and [La−] mean did not differ between 1-H (...) and 2-H. Time in intensity zones of 50–100 %HRmax differed only in 60–70 %HRmax. HR coefficient of variation throughout the match was low and among the four outfield players on the court. Substitutions, time of permanence on the court, ratio between time in- and out-ratio on the court also were similar between 1-H and 2-H. Balancing the number of substitutions, and the In:Outcourt ratio of players in both halves of the match, playing lower time at 1-H, ~8 min for each participation in the match, made it possible to maintain intensity of the match in 2-H similar to the 1H. These results are a good guidance to coaches and for application in future studies. (shrink)

The evangelical movement has shown a significant growth among the Brazilian population in recent decades, which has also manifested itself in political representation and, consequently, draws the attention for the political projects that this group raises. For this reason, studies in this area are extremely relevant to understand how this relationship between religious and seculars should take place in the public space. After analysis based on the hypothetical-deductive methodology, it was found that both religious and people with different worldviews should (...) act in the public space with respect and tolerance. Imposing a way of looking at the world goes against the essence of liberalism and the democratic rule of law, as it violates basic issues such as the right to free consciousness and religion freedom itself.

O presente artigo tem como objetivo realizar uma leitura do modo como a biopolítica, em autores como Foucault e Agamben, reflete sobre a economia em sua constituição contemporânea, desde a sua formação moderna, numa ordem que é liberal e capitalista. Em um primeiro momento, busca-se apresentar uma contextualização, indicando a relação entre Mercado e Estado no mundo moderno, destacando alguns destes aspectos fundamentais. Em seguida, almeja-se refletir e expor a relação entre a biopolítica e economia, privilegiando aquilo que Foucault realizou (...) em Nascimento da Biopolítica e, logo depois, apresentar as percepções de Agamben sobre o capitalismo, destacando o livro O Reino e a Glória. Não se propondo uma reflexão fechada, busca-se apresentar as reflexões dos autores, marcada pela leitura biopolítica, sobre a hegemonia do econômico na contemporaneidade. (shrink)

Este artigo, um recorte de pesquisa de Doutorado, objetiva desvelar as percepções de 208 professores de filosofia do Paraná no sentido de buscar evidenciar quais seriam as especificidades da disciplina de filosofia em relação a outras disciplinas do currículo. Inicialmente, disserta-se sobre a intermitência da disciplina de Filosofia no currículo da Educação Básica, com base em Deleuze e Guattari (2010), os quais demarcam o entendimento da filosofia como criação de conceitos. Em seguida, fundamentado em Rodrigues e Gelamo (2019), entre outros (...) autores, reflete-se sobre o modo de compreender a filosofia, que pode oscilar entre uma compreensão enciclopédica com base na memorização dos sistemas filosóficos e experiência filosófica. Por fim, por meio da análise de conteúdo de Bardin (2016), a seguinte questão de um questionário que envolvia outras dez foi analisada: “Você acredita que a filosofia proporciona espaços ou momentos diferenciados em relação aos das outras disciplinas? Se sim, no que ela se diferencia?”. Das respostas dos 208 docentes, emergiram as seguintes categorias: criar conceitos, espaço para o debate/reflexão de ideias, possibilidade da experiência filosófica e superar o senso comum. Os resultados apontam, assim, em um sentido de que a disciplina de filosofia não deve limitar-se a um conhecimento enciclopédico, mas, sim, trata-se de um conhecimento que se relaciona com o cotidiano de seus interlocutores. Faz-se necessário, porém, um saber valorizar adequadamente a história da filosofia, pois, ao valorizar demais a história da filosofia, pode-se incorrer a um ensino meramente descritivista; contudo, ao não valorizar a história da filosofia, pode-se debruçar em discussões sem conteúdo filosófico.

Neste artigo partimos da hipótese de que a afinidade que atrai evangélicos e conservadorismo está muito mais ligada às condições discursivas que engendram os sujeitos e suas subjetividades, do que as características intrínsecas à teologia cristã ou, especificamente, evangélica pentecostal. Com isso não queremos dizer que conformações teológicas específicas não ensejaram discursos religiosos regressivos, que a maioria de nós classificaria como conservador. Assim, chamamos a atenção, tanto para o caráter relacional, posicional das identidades evangélicas, que engendram o discurso conservador, quanto (...) para a base material deste discurso, ligando, portanto, sujeitos e formas de sujeição e subjetivação. Interessam-nos, as formas políticas em que se precipitarão os antagonismos articulados a partir dos grupos de identidade evangélica, bem como os deslocamentos na base material destes sujeitos, que possibilitam o engendramento de subjetividades atomizadas e refratárias a solidariedades coletivas exógenas a sua comunidade. Defenderemos que, embora evangélicos tenham ganhado relevo no espaço público por pautas reativas à ampliação de direitos de minorias, tais ações não se devem unicamente a aspectos intrínsecos à teologia pentecostal, ou ao seu caráter alienante ou irracional, mas, principalmente a forma como se posicionam no jogo político nacional, ou melhor, como se publicizaram, bem como a forma como o discurso de fundo conservador é acionado como estratégia de sobrevivência nas grandes cidades.

A linguagem para Nietzsche é considerada como uma metáfora das coisas externas produzida pelos estímulos que elas causam em nós. A partir disso, indagamos sobre a possibilidade da linguagem e da história auxiliarem na busca pela verdade. Para tal, o texto reconstrói o pensamento de Nietzsche contido em dois escritos de 1873 3 1874. Por fim, contrapormos a concepção de Nietzsche, ainda que brevemente, com a visão de Habermas para demonstrar que a história, expressa pela linguagem, deve ser crítica e, (...) com isso, conduzir a verdade.

Brazil stands out at the global level for having implemented several policies intending to promote agroecology as a productive paradigm for small-holder farmers. However, the impacts of this process of institutionalization of agroecology still lack research and debates that evaluate the effectiveness of these policies. In this paper, we assess and discuss the impacts of a policy specifically focused on education in agroecology, the support to the establishment of Centers for the Study of Agroecology and Organic Production (NEAs) in more (...) than 150 higher education institutions throughout Brazil. NEAs bring together teachers, researchers, and students who engage in teaching, research, and extension activities in partnerships with peasant farmers, their organizations, and rural extension workers. The hypothesis that guides our analysis is that this support to establish NEAs allowed redistribution of symbolic power in the universities where they were established, supporting agroecology to gain greater legitimacy inside and outside the university field. Based on an in-depth study of four NEAs, performed through participant observation and documentary analysis, the NEAs are evaluated from the perspective of social fields in dispute, first in a university sphere, but also from the perspective of training people in integrative and transdisciplinary thinking that will contest the industrial-corporate food regime. Our findings suggest that the State support to university groups dedicated to the promotion of agroecology has allowed the construction of what we have named agroecological spaces, which symbolically dispute the dominant paradigms in educational institutions, supporting the constitution of material and immaterial agroecological territories.

The discovery of participation of astrocytes as active elements in glutamatergic tripartite synapses (composed by functional units of two neurons and one astrocyte) has led to the construction of models of cognitive functioning in the human brain, focusing on associative learning, sensory integration, conscious processing and memory formation/retrieval. We have modelled human cognitive functions by means of an ensemble of functional units (tripartite synapses) connected by gap junctions that link distributed astrocytes, allowing the formation of intra- and intercellular calcium waves (...) that putatively mediate large-scale cognitive information processing. The model contains a diagram of molecular mechanisms present in tripartite synapses and contributes to explain the physiological bases of cognitive functions. It can be potentially expanded to explain emotional functions and psychiatric phenomena. (shrink)

ResumoO direito brasileiro foi articulado em torno das categorias clássicas do liberalismo europeu. Para além do debate da compatibilidade entre liberalismo e escravidão, esse artigo pretende demonstrar como a necessidade de preservar uma escravidão semilegal constituiu institucionalidades que fizeram com que o direito brasileiro operasse problematicamente sob o registro da tradição liberal, mesmo em relação aos seus cidadãos livres. Isso não foi um “erro” do direito, uma falha, mas foi antes uma ação inteligível dos arquitetos das formas e modos de (...) funcionamento da juridicidade nacional. Nesse sentido, esse artigo pretende apontar para a necessidade de construção de uma teoria brasileira do direito que dê conta de compreender as particularidades de um sistema jurídico profundamente afetado pelo escravismo do século XIX.Palavras-chave: História do Direito. Teoria do Direito Brasileiro. Direito da Escravidão. AbstractBrazilian Law was crafted around the classical categories of European liberalism. Beyond the debate regarding the compatibility between liberalism and slavery, this paper intends to show how the need to preserve a semi-legal slavery system created illegalities that highlighted the contradictions between Brazilian Law and the liberal tradition. The resulting tensions also created consequences for free citizens, which are the focus of this paper. It demonstrates that these consequences were not mere legal defeasibility, but rather an intelligible action shaping the national legal system. The article advocates for the necessity to build a Brazilian theory of Law that takes these aspects into consideration, accounting for the systematic impact of 19th-century slavery on the idea of legality in Brazil.Keywords: Legal History.

O objetivo do artigo é compreender e apresentar a filosofia do direito no âmbito do pensamento de Edith Stein. Sob o prisma fenomenológico, há de se analisar os conceitos axiais empregados pela autora, capazes de elucidar o sentido de direito, tais como Pessoa, Comunidade e Estado, conforme defluem de seus escritos e refletivos à luz de especialistas. Com base nesses elementos, há de se perscrutar a atualidade e aplicação do seu pensamento no contexto sociojurídico contemporâneo e as possíveis consequências desta (...) aferição. Há também de se ponderar e refletir os paradigmas hegemônicos na ciência jurídica mediante às contribuições peculiares da autora. Os resultados da análise permitem entrever a densidade dos textos de Stein, cujos aportes filosóficos podem orientar hermenêutica jurídica consistente, mediante percepção metanormativa. (shrink)

This article presents a two level hierarchical forecasting model developed in a consulting project for a Brazilian magazine publishing company. The first level uses a VARMA model and considers econometric variables. The second level takes into account qualitative aspects of each publication issue, and is based on polynomial networks generated by Genetic Programming (GP).

Statistical tests that detect and measure deviation from the Hardy-Weinberg equilibrium (HWE) have been devised but are limited when testing for deviation at multiallelic DNA loci is attempted. Here we present the full Bayesian significance test (FBST) for the HWE. This test depends neither on asymptotic results nor on the number of possible alleles for the particular locus being evaluated. The FBST is based on the computation of an evidence index in favor of the HWE hypothesis. A great deal of (...) forensic inference based on DNA evidence assumes that the HWE is valid for the genetic loci being used. We applied the FBST to genotypes obtained at several multiallelic short tandem repeat loci during routine parentage testing; the locus Penta E exemplifies those clearly in HWE while others such as D10S1214 and D19S253 do not appear to show this.

Introduction: The importance attached to ethical practice and related informed consent varies among health professionals and is further influenced by working environments, level of knowledge, experience and societal values and beliefs. The objective of this study is to evaluate the ethical conduct of professors, undergraduates and graduate students through questionnaires answered by patients. Methods: One hundred twenty patients at the dental clinics of three different dental schools in São Paulo State were interviewed based on objective and discursive questions about signed (...) informed consent, participation in scientific research, photographs during treatment, requested saliva samples, tooth donation requests, and information about tooth destination after removal. A frequency distribution was used for a statistical analysis of the data. Results: In all, 65.8% of the patients had given signed informed consent for treatment and 12.5% had not done so; 10.8% did not know if they had participated in scientific research; 54.2% were photographed during dental procedures and 47.1% of them had signed an authorization form; 6.6% were requested to provide a saliva sample and 66.6% of them had signed an authorization form to that effect; 16.1% had a tooth donation requested and 64.4% of them had signed an authorization form to that effect; and 61.3% did not know the destination of the tooth after removal, when donation was not requested. Conclusions: The majority of the patients had signed an informed consent form for treatment, photographs, saliva samples and tooth donation. This demonstrated ethical conduct towards patients on the part of professors, undergraduates and graduate students. doi: 10.5294/pebi.2017.21.1.2. (shrink)

Much forensic inference based upon DNA evidence is made assuming Hardy-Weinberg Equilibrium (HWE) for the genetic loci being used. Several statistical tests to detect and measure deviation from HWE have been devised, and their limitations become more obvious when testing for deviation within multiallelic DNA loci. The most popular methods-Chi-square and Likelihood-ratio tests-are based on asymptotic results and cannot guarantee a good performance in the presence of low frequency genotypes. Since the parameter space dimension increases at a quadratic rate on (...) the number of alleles, some authors suggest applying sequential methods, where the multiallelic case is reformulated as a sequence of “biallelic” tests. However, in this approach it is not obvious how to assess the general evidence of the original hypothesis; nor is it clear how to establish the significance level for its acceptance/rejection. In this work, we introduce a straightforward method for the multiallelic HWE test, which overcomes the aforementioned issues of sequential methods. The core theory for the proposed method is given by the Full Bayesian Significance Test (FBST), an intuitive Bayesian approach which does not assign positive probabilities to zero measure sets when testing sharp hypotheses. We compare FBST performance to Chi-square, Likelihood-ratio and Markov chain tests, in three numerical experiments. The results suggest that FBST is a robust and high performance method for the HWE test, even in the presence of several alleles and small sample sizes. (shrink)

Intentional sampling methods are non-probabilistic procedures that select a group of individuals for a sample with the purpose of meeting specific prescribed criteria. Intentional sampling methods are intended for exploratory research or pilot studies where tight budget constraints preclude the use of traditional randomized representative sampling. The possibility of subsequently generalize statistically from such deterministic samples to the general population has been the issue of long standing arguments and debates. Nevertheless, the intentional sampling techniques developed in this paper explore pragmatic (...) strategies for overcoming some of the real or perceived shortcomings and limitations of intentional sampling in practical applications.

Clearing algorithms are at the core of modern payment systems, facilitating the settling of multilateral credit messages with (near) minimum transfers of currency. Traditional clearing procedures use batch processing based on MILP - mixed-integer linear programming algorithms. The MILP approach demands intensive computational resources; moreover, it is also vulnerable to operational risks generated by possible defaults during the inter-batch period. This paper presents TORC3 - the Token-Ring Clearing Algorithm for Currency Circulation. In contrast to the MILP approach, TORC3 is a (...) real time heuristic procedure, demanding modest computational resources, and able to completely shield the clearing operation against the participating agents’ risk of default.

For the epic journey of autumn migration, long-distance migratory birds use innate and learned information and follow strict schedules imposed by genetic and epigenetic mechanisms, the details of which remain largely unknown. In addition, bird migration requires integrated action of different multisensory systems for learning and memory, and the hippocampus appears to be the integration center for this task. In previous studies we found that contrasting long-distance migratory flights differentially affected the morphological complexity of two types of hippocampus astrocytes. Recently, (...) a significant association was found between the latitude of the reproductive site and the size of the ADCYAP1 allele in long distance migratory birds. We tested for correlations between astrocyte morphological complexity, migratory distances, and size of the ADCYAP1 allele in three long-distance migrant species of shorebird and one non-migrant. Significant differences among species were found in the number and morphological complexity of the astrocytes, as well as in the size of the microsatellites of the ADCYAP1 gene. We found significant associations between the size of the ADCYAP1 microsatellites, the migratory distances, and the degree of morphological complexity of the astrocytes. We suggest that associations between astrocyte number and morphological complexity, ADCYAP1 microsatellite size, and migratory behavior may be part of the adaptive response to the migratory process of shorebirds.

Populism is widely thought to be in tension with liberal democracy. This article clarifies what exactly is problematic about populism from a liberal–democratic point of view and goes on to develop normative standards that allow us to distinguish between more and less legitimate forms of populism. The point of this exercise is not to dismiss populism in toto; the article strives for a more subtle result, namely, to show that liberal democracy can accommodate populism provided that the latter conforms to (...) particular discursive norms. What the article calls a ‘liberal ethics of populism’ turns out to be closely bound up with a broader ethics of peoplehood, understood as a way of articulating who ‘the people’ are in a way that is compatible with liberal–democratic principles of political justification. Such an ethics, concludes the article, inevitably has a much wider audience than populist political actors: its addressees are all those who seek legitimately to exercise power in the name of the people.

Populist movements have become key players in European politics. These movements are readily criticized by journalists or political rivals, yet none of the common objections to populism seems to arrest their success. This article turns to normative political theory to cultivate sensitivity to problems arising from some existing arguments against populism, and to explore possible alternatives. It offers a critical reading of prototypical liberal and conservative arguments against populism, and proposes that the principles of solidarity and procedure provide good grounds (...) for a sustainable critique of populism.

Popular sovereignty requires that citizens perceive themselves as being able to act and implement decisions, and that they are de facto causally connected to mechanisms of decision making. I argue that the two most common understandings of the exercise of popular sovereignty—which center on direct decision making by the people as a whole and the indirect exercise of democratic agency by elected representatives, respectively—are inadequate in this respect, and go on to suggest a complementary account that stresses the central role (...) of internally democratic and participatory political parties in actualising popular sovereignty, drawing on the democratic theory of Hans Kelsen.

In recent times, representation theory has become one of the most productive and interesting sub-fields in democratic theory. Arguably, the most important theoretical innovation are the so-called ‘constructivist’ approaches to political representation. These approaches play a central role in Creating Political Presence: The New Politics of Democratic Representation and The Constructivist Turn in Political Representation, two impressive volumes that take stock of the state of the art in representation theory. I discuss the two volumes by focusing on three broader and (...) interconnected themes: the problem that constructivism is meant to respond to, the tendency of representation theorists to expand the possibilities of representation as broadly as possible, and the normative aspects of political representation and how constructivists deal with them.

In their book Commitment in Dialogue, Walton and Krabbe claim that formal dialogue systems for conversational argumentation are “not very realistic and not easy to apply”. This difficulty may make argumentation theory less well adapted to be employed to describe or analyse actual argumentation practice. On the other hand, the empirical study of real-life arguments may miss or ignore insights of more than the two millennia of the development of philosophy of language, rhetoric, and argumentation theory. In this paper, we (...) propose a novel methodology for adapting such theories to serve as applicable tools in the study of argumentation phenomena. Our approach is both theoretically-informed and empirically-grounded in large-scale corpus analysis. The area of interest are appeals to ethos, the character of the speaker, building upon Aristotle’s rhetoric. Ethotic techniques are used to influence the hearers through the communication, where speakers might establish, but also emphasise, weaken or undermine their own or others’ credibility and trustworthiness. Specifically, we apply our method to Aristotelian theory of ethos elements which identifies practical wisdom, moral virtue and goodwill as components of speakers’ character, which can be supported or attacked. The challenges we identified in this case and the solutions we proposed allow us to formulate general guidelines of how to exploit rich theoretical frameworks to the analysis of the practice of language use.

Resumen En este artículo se reflexiona sobre la relación entre literatura y enfermedad, concentrando la atención en la perspectiva de Kierkegaard y de Kafka. Después de analizar la postura kierkegaardiana se pasa a la kafkiana y, finalmente, se comparan los resultados obtenidos. De este modo, se pueden apreciar las diferencias entre los dos planteamientos y, sucesivamente, utilizar los elementos en común para esbozar unas características interesantes sobre la relación entre literatura y enfermedad en los siglos XIX y XX en el (...) contexto de influencia alemana. Esto nos lleva a reflexionar sobre las conexiones causales entre la enfermedad y la literatura, y sobre el contexto social o íntimo en el cual estas se desarrollan.I analyze the topic of sickness in relation to 19th and 20th Century Literature in the Germanophile area. In particular, I examine Kierkegaard's and Kafka's perspectives. In the case of Kierkegaard, he principally wrote about sickness in his diaries, and in two important books: The Concept of Anxiety and The Sickness unto Death. However, Kafka wrote about the same theme in all his diaries. Therefore, in this study, I will compare the different perspectives of these two authors in relation to both sickness and literature. Through this, I will attempt to extract any key aspects that can be used for identifying a more general relation between sickness and literature in the 19th and 20th Centuries. To achieve this aim, I will firstly scrutinize Kierkegaard's posture, and then Kafka's posture. Following this, I will compare the findings to draw general conclusions. (shrink)

The aim of this paper is to give, using the Kripke semantics for intuitionism, a representation of finitely generated free Heyting algebras. By means of the representation we determine in a constructive way some set of "special elements" of such algebras. Furthermore, we show that many algebraic properties which are satisfied by the free algebra on one generator are not satisfied by free algebras on more than one generator.

In recent times, it has become increasingly common that elected parties and leaders systematically undermine democracy and the rule of law. This phenomenon is often framed with the term democratic backsliding or democratic regression. This article deals with the relatively little-studied topic of resistance to democratic regressions. Chief amongst the things it discusses is the rather central ethical issue of whether resisters may themselves, in their attempts to prevent a further erosion of democracy, transgress democratic norms. But the argument advanced (...) in the article is not merely about the ethics of resistance. It begins, perhaps unconventionally, by addressing the affective dimension of resistance to democratic regressions, looking in particular at the powerful feelings of anger and despair that pro-democratic citizens living under a regressive government are likely to experience. As the article argues, these feelings have not only motivational but also epistemic potential, which must be adequately theorized in order to understand how resisters can respond to the ethical challenges facing them.

The contribution of Jesuits to the different fields of knowledge, including philosophy, is historically well known. In fact, since the foundation of the Society of Jesus, in the 16th century, Jesuits from different generations and cultures have taken part in the philosophical debates of their time and their different contexts. Since the foundation of the Society of Jesus, in 1540, the Jesuits, individually and as a body, have engaged in a fruitful dialogue between the Christian tradition and different dimensions of (...) human culture. During almost five centuries, numerous Jesuits taught philosophy in academic institutions all over the world. Some of them have their names recorded in the history of philosophy. Of course, the majority of them is not anymore remembered, despite their valuable contribution to the development of the Jesuit intellectual tradition up to our times. In fact, as an heir of the Roman College, the first academic institution founded by the Society of Jesus, in 1551, the Pontifical Gregorian University, in Rome, is a witness to this tradition, which has been kept alive thanks to the discrete work of both Jesuits and lay intellectuals. Known as the University of the Nations, this institution corroborates not only the capacity of the Jesuit tradition to put faith in dialogue with reason, but also the option to take the concrete reality of each human culture and its historical context as its point of departure. The Jesuits’ willingness to engage in dialogue with different intellectual perspectives is underpinned by one of the most defining traits of the Jesuit charism, namely, the conviction that God can be found and served in all things. Accordingly, Jesuits have adopted, from the beginning, an amenable stance towards the world with its different cultures and intellectual trends. As such, Jesuits have, since the beginning, inhabited the frontiers of human thought. According to the contemporary philosopher Paul Gilbert, SJ, within the institutions under the leadership of the Society of Jesus, it was always possible to maintain an equilibrium between two principles: “intellectual unity” and “openness to the world.” Without detriment to the Jesuit identity, the companions of Ignatius have been willing to dwell in the various dimensions of human reality, in their multiplicity and plurality. Either in the renewal of Aristotle’s and Aquinas’ metaphysics, or in the dialogue with modern philosophers such as Descartes, Kant, or Hegel, and even in the inculturation in non-European contexts, the Jesuits have been able to preserve the Christian tradition through an original development of human culture in all its richness and diversity. With respect to the last century, it has to be acknowledged that a significant number of Jesuits made significant contributions, with recognized competence, to philosophy. Certainly, the 20th century was particularly complex in many respects. It would be enough to recall that this period, which brought with it unprecedented social, scientific, and technological developments, was also the stage for the two World Wars. With the emergence or consolidation of philosophical currents such as Marxism, Phenomenology, Existentialism, Structuralism, and Post-Modernism, the past century was, without any doubt, fascinating from the intellectual point of view. Jesuits such as Karl Rahner, Frederick Copleston, Bernard Lonergan, William Norris Clarke, John F. Kavanaugh, Teilhard de Chardin, Gaston Fessard, Jean Daniélou, Henri de Lubac, Michel de Certeau, Xavier Tilliette, Paul Valadier, Paweł Siwek, Ignacio Ellacuría, Francisco Taborda, Henrique de Lima Vaz and, in the Portuguese context, Diamantino Martins or Júlio Fragata, among many others, were able to engage different philosophical currents, problems and controversies of their times. Faithful to their long tradition of being present in the frontiers of thought, those Jesuits have engaged in a fruitful dialogue with these intellectual trends, offering relevant contributions to different ongoing debates. Within this context, the present volume recalls and discusses the philosophical contribution of some of the most prominent Jesuit protagonists of the intellectual interchange that took place in the 20th century. This volume also intends to celebrate the 75th anniversary of the Revista Portuguesa de Filosofia, which happens just before the inauguration of the Ignatian Year. Decreed by Father Arturo Sosa, the Superior General of the Society of Jesus, this celebratory Year will start on May 20, 2021, precisely 500 years after Ignatius of Loyola, the founder of the Jesuit Order, was wounded at the battle of Pamplona. We are happy that this volume could bring together outstanding specialists in the thought of some of the most prominent Jesuits philosophers of the last century, namely Paul Valadier, Paul Gilbert, Józef Bremer, Jacek Poznański, Alexander Maar, Patrick H. Byrne, M. Ross Romero, Carlos Alvarez, Hélio Pereira Lima, José Gama, Domingos Terra, Gabriel Flynn, Marie-Gabrielle Lemaire, José Sols Lucia, Lorena Zuchel Lovera, Pedro Pablo Achondo Moya, Enzo Solari, Massimo Borghesi, Mendo Castro Henriques, João Barbosa, and Dominique Lambert. In addition, in the celebration of the 100th anniversary of Júlio Fragata’s birth, Maria Teresa Fragata presents a memory of his life and thought. We hope that this volume may be useful to all those interested in the Jesuit philosophical tradition. Hopefully, it will stimulate scholars to pursue a fruitful and creative dialogue with contemporary philosophy, in the footsteps of the Jesuit philosophers featured here. We would like to thank all the authors and all those who, in different ways, made this volume possible. (shrink)
