In many vertebrates, the enzymatic oxidation of dietary yellow carotenoids generates red keto‐carotenoids giving color to ornaments. The oxidase CYP2J19 is here a key effector. Its purported intracellular location suggests a shared biochemical pathway between trait expression and cell functioning. This might guarantee the reliability of red colorations as individual quality signals independent of production costs. We hypothesize that the ornament type (feathers vs. bare parts) and production costs (probably CYP2J19 activity compromising vital functions) could have promoted tissue‐specific gene relocation. (...) We review current avian tissue‐specific CYP2J19 expression data. Among the ten red‐billed species showing CYP2J19 bill expression, only one showed strong hepatic expression. Moreover, a phylogenetically‐controlled analysis of 25 red‐colored species shows that those producing red bare parts are less likely to have strong hepatic CYP2J19 expression than species with only red plumages. Thus, both production costs and shared pathways might have contributed to the evolution of red signals. (shrink)

August Weismann proposed that genetic changes in somatic cells cannot pass to germ cells and hence to next generations. Nevertheless, evidence is accumulating that some environmental effects can promote heritable changes in the DNA of germ cells, which implies that some somatic influence on germ line is possible. This influence is mostly detrimental and related to the presence of oxidative stress, which induces mutations and epigenetic changes. This effect should be stronger in males due to the particular characteristics of sperm. (...) Here, we propose the hypothesis that females are able to avoid males with oxidatively damaged DNA in the germ line by using oxidative‐dependent (pre‐ and post‐mating) signals. This new hypothesis may shed light on unsolved questions in evolutionary biology, such as the benefits of polyandry, the lek paradox, or the role of sexual selection on the evolution of aging.

La presente contribución indaga una dimensión de la intensa y compleja relación intelectual entre Henri de Lubac y Michel de Certeau, graficada en el paso del Corpus Mysticum a La fábula mística. En particular nos detenemos en una arista del proyecto intelectual de Lubac que busca desempolvar las potencialidades de la simbólica medieval para contrarrestar las nefastas derivas de la racionalidad moderna. Dicho proyecto se inspira en una ontología sacramental y en la centralidad de la allegoria in factis, heredada del (...) pensamiento de los Padres de la Iglesia. La reflexión que realiza Certeau en La fábula mística muestra ser no solo la continuación del Corpus Mysticum de Lubac, sino que de manera tangencial evidencia los límites del proyecto de su maestro, a través de su atención lúcida a la ruptura nominalista. Certeau muestra así que la emergencia de la mística moderna de los siglos xvi-xvii nace como respuesta al desaplazamiento de la allegoria in factis a la allegoria in verbis, que estaría a la raíz de la desontologización del lenguaje y del cisma entre la experiencia espiritual y la teología.

El artículo, con base en un argumento de Michel Foucault: la vigencia –desde el siglo XVIII hasta hoy- de las estrategias liberales del poder para el gobierno de la población, hace una reflexión sobre la escuela actual. Argumenta que la democracia, en cuanto concreción visible de esas estrategias de poder, comporta procesos específicos en la escuela que son nombrados aquí, provisionalmente, como el tránsito desde una escuela disciplinada hasta otra conflictiva, violenta, terapéutica y falta de autoridad, es decir, indisciplinada. Pero, (...) y es el argumento fundamental, en la actualidad, más que invocar mayores cotas de libertad y de democracia para la escuela, se requiere reconocer las formas de sujeción de ese liberalismo democrático, y con ello, tal vez, proponer otras formas de estar en la escuela y en la sociedad.

Después de la publicación de su tesis doctoral titulada La acción (1893), el filósofo francés Maurice Blondel escribió algunas obras en las que trató asuntos de enorme importancia, tanto en el campo filosófico como teológico, que desarrollaron las temáticas centrales de La acción, obra que a finales del siglo XIX generó tanto revuelo en el ambiente filosófico francés. Con la conciencia de su actualidad y su inmenso valor para una perspectiva novedosa de la metafísica y el diálogo fe-razón, se pretende (...) aquí una aproximación a cuatro obras que los estudiosos del pensamiento blondeliano han llamado “menores”. El presente artículo desarrolla los principales aportes de dichas obras a la reflexión filosófica contemporánea, indagando al mismo tiempo por la filosofía de la acción en cada una de ellas. Después de una corta biografía del pensador en cuestión, se abordará el significado de la filosofía de la acción con vistas a su elucidación para el lector. Posteriormente se presentará el contexto histórico de cada obra y se mostrarán sus vínculos con La acción, para terminar con algunas reflexiones que su lectura suscita en nuestro tiempo, cuyos desafíos son similares a los que Blondel tuvo que enfrentar en su momento.

The literature addressing bias and fairness in AI models (fair-AI) is growing at a fast pace, making it difficult for novel researchers and practitioners to have a bird’s-eye view picture of the field. In particular, many policy initiatives, standards, and best practices in fair-AI have been proposed for setting principles, procedures, and knowledge bases to guide and operationalize the management of bias and fairness. The first objective of this paper is to concisely survey the state-of-the-art of fair-AI methods and resources, (...) and the main policies on bias in AI, with the aim of providing such a bird’s-eye guidance for both researchers and practitioners. The second objective of the paper is to contribute to the policy advice and best practices state-of-the-art by leveraging from the results of the NoBIAS research project. We present and discuss a few relevant topics organized around the NoBIAS architecture, which is made up of a Legal Layer, focusing on the European Union context, and a Bias Management Layer, focusing on understanding, mitigating, and accounting for bias.

La propuesta del artículo es pensar determinadas fuerzas políticas condensadas en la figura del archivo, tanto en su instrumentalización por la Policía Nacional de Guatemala, como en su trabajo de rescate histórico y en su representación en el material humano de Rodrigo Rey Rosa. Desde una crítica derridiana, entendemos al archivo como el lugar que designa el encuentro de una pulsión de conservación y una pulsión de destrucción; esto es, el encuentro entre fuerzas que tratan de olvidar y las que (...) tratan de construir una memoria. El archivo entonces se muestra como una figura subversiva por su capacidad para desestabilizar cualquier mandato. Además, su desplazamiento a espacios del arte y la literatura significa también una producción de sentido específica, donde el archivo es a veces crítico, a veces pacificador. Desde dicha posición, se tratará de analizar tanto el uso represor del archivo como la representación hecha por Rey Rosa, pensando su escritura como una práctica social y como un trabajo arqueológico preocupado por el rescate de una verdad forense y en relación con una justicia espectral. El propósito final es hacer una revisión crítica de los usos de la figura del archivo y sus formas en las políticas de olvido, memoria y justicia. (shrink)

Se analizan los resultados de una reciente encuesta levantada principalmente en la zona metropolitana de Guadalajara, México, y se destaca que, aunque la mayoría de los informantes realizaron modificaciones materiales a su entorno doméstico para adecuarlo a las nuevas condiciones exigibles, se necesita flexibilidad en los espacios arquitectónicos donde se desarrollan actividades cotidianas, por lo que es necesario que profesionales del hábitat, investigadores académicos, funcionarios gubernamentales y líderes sociales propongan formas de resiliencia ante esta nueva normalidad.

El Problema de la Adopción afirma que ciertas leyes lógicas no pueden ser adoptadas. El argumento constituye un desafío al antiexcepcionalismo lógico, en la medida en que este último debe poder justificar su afirmación de que la teoría lógica en ejercicio puede revisarse. El propósito de este artículo es responder al desafío, utilizando como unidad de análisis el concepto de Taxonomía Lexical propuesto por Kuhn. Como mostraremos, una visión sociológicamente enriquecida de las teorías científicas y la naturaleza de sus cambios (...) permite dar cuenta de un antiexcepcionalismo lógico que evita el Problema de la Adopción.

The sexual double standard refers to the acceptance of different criteria to assess the same sexual behavior in men and women. To date, the few studies that have addressed the relationship between SDS and sexual satisfaction have obtained inconclusive results. In addition, no study has analyzed sexual satisfaction in people who maintain different forms of adherence to the SDS. This study establishes three SDS typologies of adherence in two areas of sexual behavior to examine the predictive capacity of personal variables, (...) interpersonal variables and social variables in sexual satisfaction. A sample of 1194 heterosexual adults aged between 18 and 87 years, who had been in a relationship for more than 6 months, was evaluated. In men, the highest sexual satisfaction levels were obtained in the egalitarian typology in the sexual freedom area. In women, no significant differences were found between the typologies of adherence to the SDS. Regression models showed that relationship satisfaction was the main predictor of sexual satisfaction in all the typologies in both men and women. In addition, the predictive relationship of personal variables with sexual satisfaction varied according to gender and the SDS adherence type. The results show the importance of studying sexual satisfaction by taking into account not only the differences between men and women. Furthermore, it is essential to consider other differences between people; for example, the difference that derives from the way of psychologically internalizing attitude toward the SDS. (shrink)

This article seeks to identify the theoretical tools that supported Michel de Certeau's political discernment during the crisis of May 1968 in France. De Certeau's ability to elucidate the novelty and complexity of this event is linked to the intertwining of his experiences as a historian, traveller (voyageur), and Christian (specifically a Jesuit). De Certeau's articulation of a 'theology of difference' allowed him to construct the intellectual and spiritual tools that enabled a lucid discernment of May 1968. Through this theology, (...) derived from negative theology, de Certeau made the experience of faith operative at a moment of cultural crisis. The article also analyses possibilities involved in the ‘rupture’, that is, the fracture that is implied in modernity; in the notion of an event that highlights the deficiency of language, its incapacity to establish ‘a truthful communication’ in society; and the recognition of the poetic dimension of speech, which is capable of interweaving speech and action. The May 1968 event invites these elements mutually to redefine themselves. (shrink)

According to a growing body of studies, people’s ability to forecast future emotional experiences is generally biased. Nonetheless, the existing literature has mainly explored affective forecasting in relation to specific events, whereas little is still known about the ability to make general estimations of future emotional states. Based on existing evidence suggesting future-oriented disposition as a key factor for mental health, the aims of the current study were (1) to investigate the relationship between negative (NA) and positive (PA) affective forecasting (...) biases and perceived psychological well-being, and (2) to explore whether positively biased predictions are associated with resilience and foster one’s skills to cope with stressful events. To do so, we asked 85 undergraduate students to forecast PA and NA over two weeks, as well as to report their daily affect through a web-based Ecological Momentary Assessment. According to the results, positively biased PA forecasting (i.e., overestimating positive emotional states) was associated with greater perceived psychological well-being and higher resilience. When high levels of stress were experienced, participants holding an optimistic, yet biased, estimation of future PA were more likely to successfully manage stressors, thus maintaining lower levels of NA and higher levels of positive emotions. We suggest that positively biased PA forecasting is an adaptive cognitive distortion that boosts people’s resilience and mental health, thus opening new avenues for the promotion of psychological well-being.

IntroductionThe assessments of the motor symptoms in Parkinson’s disease are usually limited to clinical rating scales, and it depends on the clinician’s experience. This study aims to propose a machine learning technique algorithm using the variables from upper and lower limbs, to classify people with PD from healthy people, using data from a portable low-cost device. And can be used to support the diagnosis and follow-up of patients in developing countries and remote areas.MethodsWe used Kinect®eMotion system to capture the spatiotemporal (...) gait data from 30 patients with PD and 30 healthy age-matched controls in three walking trials. First, a correlation matrix was made using the variables of upper and lower limbs. After this, we applied a backward feature selection model using R and Python to determine the most relevant variables. Three further analyses were done using variables selected from backward feature selection model, movement disorders specialist, and all the variables from the dataset. We ran seven machine learning models for each model. Dataset was divided 80% for algorithm training and 20% for evaluation. Finally, a causal inference model using the DoWhy library was performed on Dataset B due to its accuracy and simplicity.ResultsThe Random Forest model is the most accurate for all three variable Datasets followed by the support vector machine. The CIM shows a relation between leg variables and the arms swing asymmetry and a proportional relationship between ASA and the diagnosis of PD with a robust estimator.ConclusionsMachine learning techniques based on objective measures using portable low-cost devices are useful and accurate to classify patients with Parkinson’s disease. This method can be used to evaluate patients remotely and help clinicians make decisions regarding follow-up and treatment. (shrink)

Formalised knowledge systems, including universities and research institutes, are important for contemporary societies. They are, however, also arguably failing humanity when their impact is measured against the level of progress being made in stimulating the societal changes needed to address challenges like climate change. In this research we used a novel futures-oriented and participatory approach that asked what future envisioned knowledge systems might need to look like and how we might get there. Findings suggest that envisioned future systems will need (...) to be much more collaborative, open, diverse, egalitarian, and able to work with values and systemic issues. They will also need to go beyond producing knowledge about our world to generating wisdom about how to act within it. To get to envisioned systems we will need to rapidly scale methodological innovations, connect innovators, and creatively accelerate learning about working with intractable challenges. We will also need to create new funding schemes, a global knowledge commons, and challenge deeply held assumptions. To genuinely be a creative force in supporting longevity of human and non-human life on our planet, the shift in knowledge systems will probably need to be at the scale of the enlightenment and speed of the scientific and technological revolution accompanying the second World War. This will require bold and strategic action from governments, scientists, civic society and sustained transformational intent. (shrink)

The research is developed with the use of deductive and descriptive analytical methods used to obtain information on doctrine and jurisprudence and to establish and describe specific situations in the field of Ecuadorian Medical Law respectively. The main objective is to provide scientific and doctrinal tools to understand guilt in cases of omissive conduct in Ecuadorian medical practice, as well as its comparison with other countries such as Colombia, Mexico, Cuba and Argentina, the results of the research show that the (...) doctrine in the relationship to the categories of Omission, Guilt, Guarantor Position and Permitted Risk is broad and is based on scientific-doctrinal advances of the Normative Conception of Guilt comprised between 1995 and 2022. To establish useful criteria and conclusions, the discussion focuses on defining what is considered “guilty” in the context of Medical Law, highlighting the importance of elements such as the objective duty, the harmful result and the analysis of the concomitant circumstances, emphasizing the importance of considering the context and development of the facts in cases of omissive conduct in medicine and not only the result. In relation to omissions in criminal law, a distinction is made between proper and improper and finally, it concludes by suggesting the modification of article 146 of the Organic Integral Criminal Code to guarantee due process and a effective judicial protection in matters related to health in Ecuador, specifically with regard to causality in cases of omissive conduct.

Background: COVID-19 has taken many lives worldwide and due to this, millions of persons are in grief. When the grief process lasts longer than 6 months, the person is in risk of developing Complicated Grief Disorder. The CGD is related to serious health consequences. To reduce the probability of developing CGD a preventive intervention could be applied. In developing countries like Mexico, the psychological services are scarce, self-applied interventions could provide support to solve this problem and reduce the health impact (...) even after the pandemic has already finished.Aims: To design and implement a self-applied intervention composed of 12 modules focused on the decrease of the risk of developing CGD, and increasing the life quality, and as a secondary objective to reduce the symptomatology of anxiety, depression, and increase of sleep quality. The Intervention Duelo COVID follows the principles of User Experience and is designed according to the needs and desires of a sample of the objective participants, to increase the adherence to the self-applied intervention, considered one of the main weaknesses of online interventions.Methods: A Randomized Controlled Trial will be conducted from the 22nd of December of 2020 to the first of June 2021. The participants will be assigned to an intervention with elements of Cognitive Behavioral Therapy, Acceptance and Commitment Therapy, Mindfulness and Positive Psychology. The control group will be a wait-list condition, that will receive the intervention 1.5–2 months after the pre-measurement were taken. The Power Size Calculation conducted through G*Power indicated the need for a total of 42 participants, which will be divided by 21 participants in each group. The platform will be delivered through responsive design assuring with this that the intervention will adapt to the screen size of cellphones, tablets, and computers.Ethics and Dissemination: The study counts with the approval of the Research Ethics Committee of the Autonomous University of Ciudad Juárez, México, and it is registered in Clinical Trials. The article is sent and registered in clinical trials before the recruitment started. The results will be reported in future conferences, scientific publications, and media. (shrink)

Durante la última década se ha producido un importante desarrollo de prácticas que formulan propuestas alternativas a los modos de producción, consumo e intercambio dominantes. Este artículo analiza el tejido de prácticas económicas alternativas en la ciudad de Valladolid, una ciudad media alejada de los contextos urbanos sobre los que se ha construido el cuerpo teórico que indaga en el potencial transformador de redes de consumo, mercados de trueque, bancos de tiempo, monedas sociales o huertos comunitarios. El trabajo, consciente del (...) valor del contexto y de la escala, propone para ciudades como la estudiada una relectura que sitúa dicho potencial no en el ámbito económico, sino en el de la práctica y la experiencia social y en el de la cultura política.The last decade has witnessed an important development of practices that involve alternative proposals to the dominant production, consumption and exchange patterns. In the present article, we present an analysis of the interwoven patterns of alternative economic practices in Valladolid, a mid-sized city in Spain. This urban profile differs from the cities that have typically been used to design the body of research on the transformation power that consumer networks, bartering, time banking, social coin and community orchards have. Taking into account the value of both the context and the scale under investigation, this study proposes a reanalysis for these types of cities: under this view, the potential is not placed in the economic sphere but rather in the social practice and experience as well as in the political culture.

This paper presents philosophical perspectives related to the concept of boredom from the point of view of its forms and structural modes as developed by Martin Heidegger in his lectures at the University of Freiburg during the winter semesters of 1929 and 1930. We highlight a philosophical stance often overlooked in comparison to more traditional positions in Western philosophical thought—through the proposed hermeneutic-phenomenological processes, this will allow us to interweave their philosophical images with cinematographic narratives that enrich the factual understanding (...) of modernity. For this reason, we assume boredom and its essence, “tediousness”, as the fundamental mood of our era, thus permitting other mobilities of thought that warrant a study of phenomena relating to cultural entertainment as a symptom of the modern disease that distances Dasein from meeting, questioning, and self-care.

Se emplean diferentes métodos investigativos: los teóricos, así como la técnica de discusión grupal, permitió diseñar el programa del curso para la preparación (...) de metodólogos en condiciones de universalización y los empíricos, la obtención de algunos datos de interés acerca de los metodólogos que reciben el curso y sus valoraciones en relación con el mismo. Se constata que la preparación pedagógica y experiencia en el desempeño es insuficiente para asumir el rol de metodólogo y valoran de muy importantes los contenidos desarrollados, los métodos y formas organizativas concebidas, por lo que se concluye que el programa del curso cumple con las expectativas del metodólogo al estar diseñado teniendo en cuenta las funciones que estos desempeñan y sus necesidades sentidas A study was carried out about the intervention in education developed to increase teacher's methodological preparation under their new functions due to the fresh conditions of learning within the community applied to medicine training and education in Camagüey. It was carried out in the period of September 2005 to June 2007. Different research methods were used: the theoretical ones and the technique for group discussion help to design the course syllabus and the assessment for those teachers that received the course. It was verified that the methodological preparation and performance experience are insufficient to play their role; but they value as very important the contents, the methods and the organization of the course. The authors conclude that the course meets the expectations of training, because it was designed keeping in mind the teachers' functions and their necessities. (shrink)

Background:The first wave of the COVID-19 pandemic caused a shortage of qualified nurses in Spain. As a result, the government authorized the hiring of senior students.Objectives:To explore the ethical dilemmas and ethical conflicts experienced by final-year nursing students who worked during the first outbreak of the COVID-19 pandemic in Spain.Research design:A qualitative exploratory study was conducted using purposive sampling. Semi-structured interviews were carried out using a question guide. Interviews took place via a private video chat room platform. A thematic, inductive (...) analysis was performed of the information gathered.Participants and research context:Eighteen nursing students were recruited from two universities of Madrid, aged between 18 and 65 years old, enrolled in the fourth year of nursing studies and who were hired under a relief contract for health professionals during the pandemic.Ethical considerations:The present study was carried out in accordance with the Declaration of Helsinki, and the study was approved by the Local Ethics Committee of Universidad Rey Juan Carlos.Results:Three specific themes emerged: (a) coping with patient triage, (b) difficulties in providing end-of-life care, and (c) coping with patient death. Nursing students participated in the process of patient selection for resource allocation and ICU bed occupancy. They were shown how to care for patients who were not admitted to the ICU, in their last moments and were faced with the difficulties of applying end-of-life care. Finally, the nursing students were confronted with the death of their patients, in overwhelming numbers and under adverse conditions.Conclusions:These findings can help shed light on the ethical dilemmas and ethical conflicts faced by novice nursing students, incorporated into the workforce during the COVID-19 pandemic. Moreover, it was described that students may normalize the death due to the exhaustion and overwhelmed routine. (shrink)

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)
