The aim of this paper is to propose a self-representational theory of phenomenal consciousness from Sartre. For it I will clarify and show the closeness of two ideas. The first of these is the so-called self-representational theory of consciousness, which holds that a mental state is conscious if and only if it represents itself in the right way. The second of these are the descriptions of consciousness from Sartre, which say that all consciousness is self-consciousness of itself, or more precisely: (...) every positional consciousness of an object is at the same time a non-positional consciousness of itself. With the above, the phenomenal consciousness would be self-consciousness of itself and the self-consciousness of itself would be self-representation. (shrink)

Business Ethics: A European Review, EarlyView.

Analiza la forma en que el pensamiento baconiano -alianza entre ciencia, matemática y filosofía- se instituye en ideología de la modernidad y en referente universal de todo tipo de conocimiento. La epistemología positiva pretende la depuración del conocimiento científico, la demarcación entre la ciencia y pseudociencia, así como la apoteosis de la razón instrumental. El libro analiza algunas de las alternativas al positivismo: Lakatos, Kuhn, Habermas, además de la sociología cognitiva de la ciencia. Se propone un programa basado en la (...) recuperación del control social de la ciencia y la tecnología. (shrink)

El principal problema del panpsiquismo es el problema de la combinación. Como solución se distinguen dos tipos de panpsiquismo: el panpsiquismo constitutivo y el panpsiquismo emergentista. Pero esta distinción opera sobre la distinción entre fundación y causalidad. Sin embargo, se verán razones para considerar que causalidad y fundación no son distintos. De modo que la distinción entre los anteriores panpsiquismos colapsa. Posibilitando la postulación de un nuevo tipo de panpsiquismo, el panpsiquismo de construcción. También, se trazará un primer esbozo de (...) solución para el problema de la combinación desde el punto de vista del panpsiquismo de construcción. (shrink)

Background Biomedical and ethnographic studies among indigenous people are common practice in health and geographical research. Prior health research misconduct has been documented, particularly when obtaining genetic material. The objective of this study was to crossmatch previously published data with the perceptions of the Waorani peoples about the trading of their genetic material and other biological samples. Methods We conducted a mixed methods study design using a tailored 15-item questionnaire in 72 participants and in-depth interviews in 55 participants belonging to (...) 20 Waorani communities about their experiences and perceptions of participating in biomedical research projects. Additionally, we conducted a systematic review of the literature in order to crossmatch the published results of studies stating the approval of an ethics committee and individual consent within their work. Results A total of 40 men and 32 women, with a mean age of 57 ± 15 years agreed to be interviewed for inclusion. Five main categories around the violation of good clinical practices were identified, concerning the obtention of blood samples from a recently contacted Waorani native community within the Amazonian region of Ecuador. These themes are related to the lack of adequate communication between community members and researchers as well as the voluntariness to participate in health research. Additionally, over 40 years, a total of 38 manuscripts related to the use of biological samples in Waorani indigenous people were published. The majority of the studies did not state within their article obtaining research ethics board approval, and 71% did not report obtaining the informed consent of the participants prior to the execution of the project. Conclusion Clinical Research on the Waorani community in the Ecuadorian Amazon basin has been performed on several occasions. Unfortunately, the majority of these projects did not follow the appropriate ethical and professional standards in either reporting the results or fulfilling them. The results of our investigation suggest that biological material, including genetic material, has been used by researchers globally, with some omitting the minimum information required to guarantee transparency and good clinical practices. We highlight the importance of stating ethics within research to avoid breaches in research transparency. (shrink)

El presente trabajo se construye alrededor de dos ejes centrales: el aprendizaje rizomático y la era posdigital. El aprendizaje rizomático asienta sus principios en la construcción del conocimiento a partir de las aportaciones del alumnado en tiempo real, con la finalidad de entender la comunidad como currículo. Por su parte, la era posdigital se entiende como la coyuntura en que la tecnología digital es una necesidad social impuesta. Partiendo de que la educación, pese a ser pública, no es gratuita, la (...) digitalización aumenta la brecha socioeconómica entre elalumnado con acceso a herramientas digitales y el que no. Así, se propone la posibilidad de contradigitalización:usar la tecnología digital como una herramienta emancipadora más. Esto es, cuando sea posible, utilizarla de manera competente y equitativa. Ahora bien, cuando esta situación no pueda darse debemos contar con una práctica posdigital que comprenda el sistema-mundo con las mismas o similares posibilidades. Para ello,aprendizaje rizomático y era posdigital serán presentados como núcleos inherentes a la producción de la propuesta pedagógica viniente: la posibilidad de establecimiento de una pedagogía posdigital. Como sustento filosófico se presenta una revisión de literatura de los dos ejes mencionados desde la obra de Deleuze y Guattari,exponiéndose un acercamiento rupturista con las posiciones digitalistas de la educación tecnocapitalista actual.

Background: The high level of satisfaction of users of a health service is largely due to the fact that they receive excellent care from healthcare professionals. Compassionate care is an essential component of excellent care. But what do nurses understand compassion to be? Research objectives: To analyse the concept of compassion from the perspective of nurses in the Andalusian Public Health System, Spain. Research design: This is a qualitative study following the grounded theory model. Four focus groups and 25 in-depth (...) interviews were conducted. Participants and research context: A total of 68 nursing professionals working in the Andalusian Public Health System (Spain) participated. Theoretical sampling was used, with participants being recruited using the snowball technique. Ethical considerations: This research was approved by the Research Ethics Committee of the Centro-Almería Health District (CEICA 27/9/17). Findings: From the analysis of the data, four themes emerged that helped to understand the concept of compassion according to nurses: ‘Negative perception of the term compassion’, ‘Compassion and empathy as synonyms’, ‘Beyond empathy’, and ‘Effects of having a compassionate attitude’. Discussion: Nurses perceive the concept of compassion differently to each other and even contradictorily. This concept is imbued with cultural elements, which adds confusion to understanding it, and is even perceived as something negative similar to pity. Conclusion: Nurses confuse the concepts of empathy and compassion as if they were synonymous. Before considering training in compassion for healthcare professionals, it is essential to clarify the concept of compassion through educational interventions. (shrink)

El presente artículo pone en diálogo dos teorías sobre la justicia frente al fenómeno migratorio, específicamente, aquel que corresponde a la movilización masiva de ciudadanos venezolanos a Colombia desde el caso particular de la ciudad de Bucaramanga. Lo anterior tiene por objetivo proponer alternativas frente a los principales conflictos que han surgido con el choque cultural, político y económico que conlleva una movilización de esta envergadura en un país poco capacitado. Para conseguir esta meta, se proponen tres momentos; primero, se (...) exponen en conjunto tanto la teoría de Jürgen Habermas como la de Jacques Derrida, el primero de estos al respecto de la relación justicia-tolerancia, mientras que el segundo lo hace desde la dupla justicia-hospitalidad. Seguidamente, se exponen algunos puntos principales para ser analizados sobre la ola migratoria en Colombia, de modo que, finalmente, se pueda hacer una lectura desde el aparato conceptual de ambos autores a la problemática migratoria en la ciudad de Bucaramanga.

Relationships between degree/area of academic formation and religious and Darwinian views are controversial. This study aimed to compare the religious beliefs and acceptance of Darwinian evolution between two contrasting South American scientific communities (Chile and Colombia), accounting for different degrees and areas of academic formation. In 2018, 115 last year bachelor students (surveyed as freshmen in 2014 for a previous study) from Chile, and 283 first/last year bachelor students, graduate students, and professors from Colombia, all belonging to biology, chemistry, or (...) physics, were surveyed. Chilean students/faculty were significantly more agnostic/atheist, more accepting of Darwinian evolution, and less creationist than their Colombian counterparts. Academic degree and area differently affected these views in both countries, as only in Chile there was a clear tendency among biologists and physicists with higher degrees to hold less religious and creationist views. Marked differences between the history, socioeconomic contexts, and especially in high school and university curricula of both countries might explain these results. (shrink)

The concept of vital force – the immanent energy that promotes the processes of life in the body and in nature – has proved a source of endless fascination and controversy. Indeed, the question of what vitalizes the body has haunted humanity since antiquity, and became even more pressing during the Scientific Revolution and beyond. Examining the complexities and theories about vital force in Spanish modernity, Nicolás Fernández-Medina's Life Embodied offers a novel and provocative assessment of the question of (...) bodily life in Spain. Starting with Juan de Cabriada's landmark Carta filosófica, médico-chymica of 1687 and ending with Ramón Gómez de la Serna's avant-gardism of the 1910s, Fernández-Medina incorporates discussions of anatomy, philosophy, science, critical theory, history of medicine, and literary studies to argue that concepts of vital force served as powerful vehicles to interrogate the possibilities and limits of corporeality. Paying close attention to how the body's capabilities were conceived and strategically woven into critiques of modernity, Fernández-Medina engages the work of Miguel Boix y Moliner, Martín Martínez, Diego de Torres Villarroel, Sebastián Guerrero Herreros, Ignacio María Ruiz de Luzuriaga, Gaspar Melchor de Jovellanos, Pedro Mata y Fontanet, Ángela Grassi, Julián Sanz del Río, Miguel de Unamuno, and Pío Baroja, among others. Drawing on extensive research and analysis, Life Embodied breaks new ground as the first book to address the question of vital force in Spanish modernity. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:THE DOMINICAN SCHOOL OF SALAMANCA AND THE SPANISH CONQUEST OF AMERICA: SOME BIBLIOGRAPHICAL NOTES THOMAS F. O'MEARA. O.P. University of Notre Dame Notre Dame, Indiana SALAMANCA, northwest of Madrid and Avila and not far from Spain's border with Portugal, preserves the atmosphere of a medieval, Renaissance, and Baroque university even as it develops the schools and clinics of a contemporary center of studies. There are associations with Teresa of (...) Avila, who spent the night there just after her reform was approved by Rome, with the young Cervantes, with Luis de Leon and Ignatius Loyola, and with John of the Cross, who was a student there. A bridge from the time of Trajan spans the river Tormes, and the Romanesque cathedral still reserves a chapel for the Mozarabic rite. The University of Salamanca The city brings to mind sixteenth century Dominicans like Francisco de Vitoria, often called the founder of international law, and Domingo Bafiez, confessor to Teresa of Avila. The Order of Friars Preachers, however, came to Salamanca in 1222 at the same time that Dominic's missions were taking root in·Paris and Bologna; the friars founded a priory and soon a school under the patronage of St. Stephen (San Esteban). The " Dominican School of Salamanca " means formally the line of great theologians reaching from Diego de Deza at the end of the fifteenth century to Tomas de Lemos, a main protagonist in Rome in 1607 in the controversy over grace entitled De Auxiliis. Today, after seven and a half centuries of existence, the Salamancan SSS 556 THOMAS F. o'MEARA, O.P. Dominicans remain a vital community, active m teaching, research and publishing. My attention was directed to the Dominicans at Salamanca by two volumes of essays reporting on congresses concerning the "Dominicans and the Discovery of the New World." My interest was not church history but the history of theologies of how grace might exist outside of explicit faith and sacramental baptism. The following report is a bibliographical survey of recent research on a theological era and school. Focusing on the thought of the theologians stimulated by the experiences of the missionaries in the Indies, it treats the Dominicans during the first decades after the voyages of Columbus. In the 1480s, as it entered its golden age, the University of Salamanca had a hundred professors and almost 7000 students. University records begin late, but they show that in 1546/47, one hundred thirty-four Dominicans were studying at the university, and in 1598/99, eighty. J. L. Espinel has written. a historical guide to the Dominican buildings and institutions.1 The great period of the Dominican school at the University began with Diego de Deza ( 1480-1486), professor and archbishop of Seville, and Matias de Paz (1518-1519), a professor of Scripture. Francisco de Vitoria (1526-1546) and Domingo de Soto (15321549 ) were its most gifted thinkers, but the school's achievements continued with Melchior Cano (1546-1552), Juan de la Pefia (1561-1565) and Domingo Banez (1581-1604).

A Salamancan Dominican of the 1930s, Vicente Beltran de Heredia, pioneered research in the history of the university and in the writings of the Dominican speculative masters.

I argue that Diego Alvarez and Thomas de Lemos through their participation in the De auxiliis controversy developed and defended Cajetan’s view of the causation of sin in such a way that they were able to defend the predetermination of the material aspect of sin while at the same time assimilating important aspects from his critics. It is important to recognize that Lemos and his associates hold both that the premotion of sin’s material aspect is not necessarily connected with (...) the Catholic faith and that it is knowable by natural reason. Even though they argued that other Molinist theses should be condemned as heretical, they held that this rejection of the Dominican thesis concerning sin is simply wrong but not heretical. First, I consider Cajetan’s position. Second, I consider the reception of this position by Medina, Zumel, and Báñez. Third, I show that Alvarez and Lemos make distinctions that allow them to incorporate the insights of both Cajetan and his critics. (shrink)

This paper uses the conceptual apparatus of Wittgenstein’s later philosophy to tackle a foundational issue in the philosophical literature on group identity, namely, the problem of difference. This problem suggests that any appeal to a collective identity is oppressive because it imposes a shared identity on the members of a group and suppresses the internal differences of the group. I develop a Wittgensteinian view of identity that dissolves this problem by showing the conceptual confusions on which it rests. My Wittgensteinian (...) view of identity tries to establish two main theses: first, that identity is bound up with difference and presupposes heterogeneity; and second, that the solidarity of identity groups, far from being obstructed by differences, actually requires diversity. Drawing from gender and sexuality studies, I use the mechanism of disidentification to show how there can be shared identities and identity-based solidarity without the erasure of differences. Key Words: community • difference • ethnicity • familial view • gender • identity • race • sexuality • solidarity • Wittgenstein. (shrink)

This article explores how racist propaganda works in visual communication and how such propaganda can be resisted. The article analyzes how photography has created new possibilities for the insidious dissemination of racist messages and discusses ways of resisting these visually transmitted propagandistic messages. The two sections of the article focus on examples of racist propaganda in visual culture: in section 1, the focus is on the propagandistic use of photography in the early twentieth century by the pro‐lynching movement; and in (...) section 2, the focus is on racist subtexts in communication that is both visual and verbal in mass media in recent decades. In both sections, the paper discusses how to neutralize and counter propaganda in visual culture by means of what the author terms “epistemic activism,” which consists in practices of interrogation and resistance that unmask, disrupt, and uproot biases and insensitivity. The article discusses different instances of epistemic activism that make explicit and effectively criticize racist subtexts in visual communication. The instances of epistemic activism discussed include the pamphlets of the anti‐lynching movement, critiques of visual artists and scholars, and the critical responses of online activists. The article argues that epistemic activism can produce critical viewership by disrupting the passive reception of visual messages and triggering more active and critical modes of viewing images. The author concludes by emphasizing the urgent need for epistemic activism that promotes critical awareness of the subtexts embedded in visual communication and a sense of critical responsibility in the production, consumption, and recirculation of images.

This article addresses the question raised by the Anthropocene of rethinking the concept of autonomy which, in the conditions of the new geological epoch, is subject to a crisis of legitimation. It explores the ‘strong hypothesis’ according to which nature is a necessary condition of our qualitative experience of the world and a constitutive relation of autonomy defined as the self-realisation of individual identity. With this aim in mind, the article attempts to rethink the concept of recognition in order to (...) conceive a recognising attitude of nature in the form of love of nature as a form of adequate recognition. Rethinking recognition can serve as foundation of an ‘objective’ theory of autonomy, that is, a theory that explains how nature can be defined as a condition and constitutive relation of autonomy. The article, therefore, proposes to reformulate the concept of autonomy as the self-realisation of an ecological or environmental identity in the form of the self-realisation of an ecological ethos, that is, an attitude of respect and care for nature. This enquiry, ultimately, is a contribution to the task of rethinking the basis of our conceptions of autonomy and freedom in the Anthropocene, so that the idea of autonomy can legitimately constitute the central value of the social transformation that is needed to face the ecological crisis.

Bioethics should pay more attention to globalization and some of its consequences than it has done so far. The COVID-19 pandemic would not have been possible without globalization, which has also increased some of its negative consequences. Globalization has intensified wildlife trade in the world. One of the main hypotheses about the origin of this pandemic is that it originated in illegal forms of wildlife trade in China. In the last 30 or 40 years, there have been zoonotic outbreaks at (...) a much frequent pace than before, many of those have been related to wildlife trade. Legal and illegal wildlife trade has grown in the shadow of globalization. Second, globalization has had a huge impact on the redistribution of wealth in the world. Since 1990 income inequality has increased in most high- and in many middle- and low-income countries. A country’s level of pre-COVID income inequality is the best predictor of the COVID death rate. These two issues are not unrelated. People living in poverty in LMIC tend to suffer more from infectious diseases and tend to be marginalized from the health sector. Additionally, poverty tends to reproduce the conditions under which zoonotic diseases can more easily spread. (shrink)

The quasispecies theory is a helpful concept in the explanation of RNA virus evolution and behaviour, with a relevant impact on methods used to fight viral diseases. It has undergone some adaptations to integrate new empirical data, especially the non-deterministic nature of mutagenesis, and the variety of behavioural motifs in cooperation, competition, communication, innovation, integration, and exaptation. Also, the consortial structure of quasispecies with complementary roles of memory genomes of minority populations better fits the empirical data than did the original (...) concept of a master sequence and its mutant spectra. The high productivity of quasispecies variants generates unique sequences that never existed before and will never exist again. In the present essay, we underline that such sequences represent really new ontological entities, not just error copies of previous ones. Their primary unique property, the incredible variant production, is suggested here as quasispecies productivity, which replaces the error-replication narrative to better fit into a new relationship between mankind and living nature in the twenty-first century.

ABSTRACTSince 2007, when Mexico City decriminalized abortion during the first trimester, a debate has been taking place regarding abortion and the right to conscientious objection. Many people argue that, since the provision of abortions is now a statutory duty of healthcare personnel there can be no place for “conscientious objection.” Others claim that, even if such an objection were to be allowed, it should not be seen as a right, since talk about a right to CO may lead to a (...) slippery slope where we may end up recognizing a right to disobey the law. In this paper, I argue that there is a right to CO and that this may be justified through the notions of autonomy and integrity, which a liberal democracy should respect. However, it cannot be an absolute right, and in the case of abortion, it conflicts with women’s reproductive rights. Therefore, CO should be carefully regulated so that it does not obstruct the exercise o... (shrink)

For different reasons, Husserl's original, thought-provoking ideas on the philosophy of logic and mathematics have been ignored, misunderstood, even despised, by analytic philosophers and phenomenologists alike, who have been content to barricade themselves behind walls of ideological prejudices. Yet, for several decades, Husserl was almost continuously in close professional and personal contact with those who created, reshaped and revolutionized 20th century philosophy of mathematics, logic, science and language in both the analytic and phenomenological schools, people whom those other makers of (...) 20th century philosophy, Russell, Frege, Wittgenstein and their followers, rarely, if ever, met. Independently of them, Husserl offered alternatives to the well-trodden paths of logicism, nominalism, formalism and intuitionism. He presented a well-articulated, thoroughly argued case for logic as an objective science, but was not philosophically naive to the point of not seeing the role of subjectivity in shaping the sense of the reality facing objective science. Given the preeminent role that philosophy of logic and philosophy of mathematics have played in transforming the way philosophy has been done since Husserl's time, and given the depth of his insights and his obvious expertise in those fields, his ideas need to be integrated into present-day, mainstream philosophy. Here, philosopher Claire Ortiz Hill and mathematician-philosopher Jairo da Silva offer a wealth of interesting insights intended to subvert the many mistaken idees recues about the development of Husserl's thought and reestablish broken ties between it and philosophy now.

In recent years, after various scandals, the role of auditors has been called into question, even casting doubt on whether their reports reliably reflect the true financial situation of the auditee, especially when this situation is not good. Normative changes in the way auditors have to rate certain questions provide a good opportunity to study this problem. These changes have acquired great relevance among the factors involved in studying audit quality. Thus, the present study analyzed the effect of the normative (...) change that took place in Spain in December 2010, related to opinions modified for going-concern uncertainties. Until that date, the auditor’s uncertainty about the company’s going-concern status led to a qualified opinion. However, under the new regulation, it became an opinion that included an explanatory paragraph stating the reasons for concern, which was considered less serious. In all, 152 small- and medium-sized enterprises that had begun bankruptcy proceedings were studied. Expert systems were used for their analysis, based on classification trees assembled through boosting and bagging. In addition, the logistic regression was used as baseline to compare previous methods. The main result obtained was that a change in the norm that catalogs the going-concern issue as less serious made auditors more likely to report this situation, thus questioning the audit quality.

In this paper, an argument by Fisher (2004) is formalized and evaluated by means of some tools of classical logic. The argument presented by Fisher is a version of a piece of reasoning of great historical importance known as Pascal’s Wager. According to Fisher, “this is a fascinating piece of reasoning. It is complex and important and hard to handle”. Here is shown that, although formal logical analysis has limitations to evaluate everyday deductive arguments, it is perfectly capable to formalize (...) and evaluate Fisher’s argument. This should show that its usefulness is undeniable. (shrink)
