The present study focuses on a grammatical category called evidentiality. The primary meaning of evidentiality is concerned with information source. That is, it expresses whether something has been seen, heard or inferred. The aim here is to conduct a conceptual study of evidentiality in which use is made of formal tools. The fundamental intuition is that the distinction between ‘evidence’as ‘proof’and ‘evidentiality’as ‘to do with proof’is a crucial one. Evidentiality is a dynamic notion to be analysed through the use of (...) knowledge by the agents, a knowledge in action, which involves an in-coming state and an out-coming state that is typical of the transmission of information. We propose our own approach in which the dynamics of knowledge in action is grasped in the context of a dynamic epistemic logic. (shrink)

The aim of this article is to analyse the kind of inference used in the reconstruction of proto-languages. Hypothesis is at the core of this reconstruction process and this, together with the structure of reasoning involved, indicates abductive reasoning. We analyse abductive reasoning, and specify its nuances and particularities. The novelty we introduce is the importance of context as we focus on a form of abduction that goes beyond the context in which the scientific work is being developed by incorporating (...) contexts from other sciences. Therefore, an intercontextual chain of inference can be part of abductive reasoning processes and the resulting hypothesis remains provisional. Several disciplines, such as archaeology, history and linguistics, play a cognitive role in the reconstruction of proto-languages, thus requiring more than one context. We use the case of the reconstruction of proto-Semitic and the unexpected fact of the Ugarit and Ebla discoveries (plus Amorite names). This sample may shed light on the use of abduction to explain certain scientific practices. (shrink)

The negative particles lā/ ’al in Ugaritic change from positive to negative in modal contexts, conditional, questions, disjunctions, etc. They have usually been studied from a Semitic and linguistic points of view. On the basis of their occurrence in Ugaritic texts, we pretend to explain their uncommon behaviour from a philosophical and logico-semantic perspective. Is it possible to translate this linguistic structure in our Modern languages? Starting from a general view of their use in Ugaritic language, we claim that this (...) phenomenon can be more clearly understood in relation to modality. We interpret these negation as a negative evidential paradigm and we explain how they change in different contexts. Methodologically, we make use of formal tools of Dynamic Epistemic Logic in order to provide a more fine-grained understanding of these negations, and their dynamics. (shrink)

Mirativity is a grammatical category or a linguistic strategy that makes explicit the surprising aspect of a piece of information. Different mirativity strategies appear in different languages. Evidentiality is a grammatical category that explicitly expresses the source of information, i.e. if something has been seen, heard or inferred. Whether mirativity forms part of evidentiality is an open question. An agent makes use of a mirativity marker when she or he expresses something about a surprising fact with respect to her or (...) his background knowledge. But there are different kinds of mirativity markers. Some of them are simple and direct and others, more complex, involve inferential processes. Here, we focus on complex mirativity and we compare it with inferred evidentials and deferred realizations. Our proposal goes beyond the purely linguistic analysis, since we try to interpret mirativity, and its role in interaction, as forming part of or involving a particular kind of inference, namely abduction. Mirativity can be used to express the surprising state that triggers an abductive reasoning but it can also encapsulate its result in such a way that it can be understood in relation to evidentiality. Thus, at least in some cases of complex mirativity, mirativity may convey indication about the source of information. Interesting for studies on dialogue is that they also indicate the degree of commitment of the speakers with the content of their own utterances. (shrink)

This book discusses how scientific and other types of cognition make use of models, abduction, and explanatory reasoning in order to produce important and innovative changes in theories and concepts. Gathering revised contributions presented at the international conference on Model-Based Reasoning, held on October 24–26 2018 in Seville, Spain, the book is divided into three main parts. The first focuses on models, reasoning, and representation. It highlights key theoretical concepts from an applied perspective, and addresses issues concerning information visualization, experimental (...) methods, and design. The second part goes a step further, examining abduction, problem solving, and reasoning. The respective papers assess different types of reasoning, and discuss various concepts of inference and creativity and their relationship with experimental data. In turn, the third part reports on a number of epistemological and technological issues. By analyzing possible contradictions in modern research and describing representative case studies, this part is intended to foster new discussions and stimulate new ideas. All in all, the book provides researchers and graduate students in the fields of applied philosophy, epistemology, cognitive science, and artificial intelligence alike with an authoritative snapshot of the latest theories and applications of model-based reasoning.

Jenner (1749–1826) is known as the father of the smallpox vaccine. Through an inferential analysis of Jenner’s report of inquiry, in which medical practice and medical research are intrinsically intertwined, we highlight his use of abductive hypotheses. Our understanding of abduction is based on the Gabbay and Woods (2005, The Reach of Abduction Insight and Trial, 2, 39) model, in which hypotheses can be activated even when they have not been confirmed, as well as Magnani’s Select and Test model (1992, (...) 2017). We discuss the fundamental role of abductive hypotheses in experimental medicine and understood in the sense of Bernard (1865, Introduction à l’étude la médecine expérimentale). We conclude with remarks about mechanistic hypotheses discussed by Jenner, in relation to the thesis advocated by Russo and Williamson (2007, Int. Stud. Philos. Sci., 21, 157–170). (shrink)

Al acercarnos al razonamiento médico debemos tener en cuenta no sólo el razonamiento clínico, sino también el razonamiento del médico en el ámbito de las investigaciones biomédicas. Además, el razonamiento clínico involucra no sólo el diagnostico, sino también la terapia, la monitorización y aspectos más generales de la investigación médica como procesos fundamentales. En todos estos casos tenemos esquemas inferenciales que pasan de la introducción de hipótesis abductivas, a la predicción deductiva de las consecuencias y la comprobación inductiva mediante pruebas (...) empíricas. Sin embargo, no siempre estos esquemas de razonamiento siguen este orden, sino que a veces las abducciones son seguidas de otras abducciones. En este artículo, proponemos un análisis del razonamiento médico basado en el modelo Gabbay y Woods de la abducción y el modelo Select and Test de Magnani para dar cuenta del uso de las hipótesis abductivas. Concluimos con una discusión de la introducción de las hipótesis en relación con el debate sobre las evidencias estadístico-probabilísticas y mecanicista en las ciencias biomédicas, y la tesis abogada por Russo y Williamson sobre su complementariedad. Nos diferenciamos de ellos en que consideramos los mecanismos como hipótesis abductivas que sirven para guiar la experimentación. (shrink)

The ability of the medical profession to sustain life, or more appropriately, to prolong dying, in patients with terminal illness, creates a most complex and controversial situation for all involved: the patient, if mentally alert; the patient's family; and the medical care team including physicians, nurses and attendants. This situation is especially complex in large acute care hospitals where medical and nursing students, residents and house officers receive advanced medical training. A major problem, prolonging the dying of the terminally ill, (...) with its medical, legal, ethical and economic complexities now confronts American society. The problem is particularly acute in teaching hospitals, in which one finds a disproportionate number of terminally ill patients. The ability to work at these questions as a community rather than as adversaries will determine much about the ability of the health care system to respect the dignity and autonomy of those who seek aid and comfort when faced with serious illness and impending death. Better communication between the physicians, health care providers, the lawyers and ethicists must be developed in order to solve these problems. Over the next ten years society and our elected representatives will be making very demanding decisions about the use of the health dollar. One possible way to prevent increasing costs is to reach significant agreement on the proper care of the dying. Proper care for the dying is being considered, discussed, and evaluated by very thoughtful people. It is not governments which should decide who is to live or who is to die. There is the serious problem of the 'slippery slope' to euthanasia by omission if cost containment becomes the major force in formulating policy on the proper care of the dying. (shrink)

A lo largo del siglo XIX mexicano, la definición de las relaciones entre la Iglesia y el Estado estuvo siempre en la mesa de la discusión pública. Desde la independencia y hasta el movimiento de Reforma, se trató de delimitar el papel que la institución eclesiástica debía ocupar en la nueva nación. Así, a mediados de siglo se reconfiguró en respuesta la secularización que se produjo en México y en gran parte del mundo occidental.

Studies have shown that as MRI T2 relaxation time lengthens there is a shift toward more unbound or “free-water” and less partitioning of the protein/lipid molecules per unit volume. A shift toward less water partitioning or lengthened MRI T2 relaxation time is linearly related to reduced high frequency EEG amplitude, reduced short distance EEG coherence, increased long distance EEG coherence, and reduced cognitive functioning (Thatcher et al. 1998a; 1998b).

Argumentation is a form of reasoning where a claim is accepted or rejected according to the analysis of the arguments for and against it; furthermore, it provides a reasoning mechanism able to handle contradictory, incomplete and uncertain information in real-world situations. We combine Bipolar Argumentation Frameworks (an extension of Dung’s work) with an Algebra of Argumentation Labels modeling two independent types of interaction between arguments, representing meta-information associated with arguments, and introducing an acceptability notion that will give more information for (...) arguments acceptability.

At the beginning of 2020, COVID-19 became a global problem. Despite all the efforts to emphasize the relevance of preventive measures, not everyone adhered to them. Thus, learning more about the characteristics determining attitudinal and behavioral responses to the pandemic is crucial to improving future interventions. In this study, we applied machine learning on the multi-national data collected by the International Collaboration on the Social and Moral Psychology of COVID-19 (N = 51,404) to test the predictive efficacy of constructs from (...) social, moral, cognitive, and personality psychology, as well as socio-demographic factors, in the attitudinal and behavioral responses to the pandemic. The results point to several valuable insights. Internalized moral identity provided the most consistent predictive contribution—individuals perceiving moral traits as central to their self-concept reported higher adherence to preventive measures. Similar was found for morality as cooperation, symbolized moral identity, self-control, open-mindedness, collective narcissism, while the inverse relationship was evident for the endorsement of conspiracy theories. However, we also found a non-negligible variability in the explained variance and predictive contributions with respect to macro-level factors such as the pandemic stage or cultural region. Overall, the results underscore the importance of morality-related and contextual factors in understanding adherence to public health recommendations during the pandemic. (shrink)

8 March, now known as International Women’s Day, is a day for feminist claims where demonstrations are organized in over 150 countries, with the participation of millions of women all around the world. These demonstrations can be viewed as collective rituals and thus focus attention on the processes that facilitate different psychosocial effects. This work aims to explore the mechanisms involved in participation in the demonstrations of 8 March 2020, collective and ritualized feminist actions, and their correlates associated with personal (...) well-being and collective well-being, collective efficacy and collective growth, and behavioral intention to support the fight for women’s rights. To this end, a cross-cultural study was conducted with the participation of 2,854 people from countries in Latin America and Europe, with a retrospective correlational cross-sectional design and a convenience sample. Participants were divided between demonstration participants and non-demonstrators or followers who monitored participants through the media and social networks. Compared with non-demonstrators and with males, female and non-binary gender respondents had greater scores in mechanisms and criterion variables. Further random-effects model meta-analyses revealed that the perceived emotional synchrony was consistently associated with more proximal mechanisms, as well as with criterion variables. Finally, sequential moderation analyses showed that proposed mechanisms successfully mediated the effects of participation on every criterion variable. These results indicate that participation in 8M marches and demonstrations can be analyzed through the literature on collective rituals. As such, collective participation implies positive outcomes both individually and collectively, which are further reinforced through key psychological mechanisms, in line with a Durkheimian approach to collective rituals.

BackgroundRespect for autonomy is a key concept in contemporary bioethics and end-of-life ethics in particular. Despite this status, an individualistic interpretation of autonomy is being challenged from the perspective of different theoretical traditions. Many authors claim that the principle of respect for autonomy needs to be reconceptualised starting from a relational viewpoint. Along these lines, the notion of relational autonomy is attracting increasing attention in medical ethics. Yet, others argue that relational autonomy needs further clarification in order to be adequately (...) operationalised for medical practice. To this end, we examined the meaning, foundations, and uses of relational autonomy in the specific literature of end-of-life care ethics.MethodsUsing PRESS and PRISMA procedures, we conducted a systematic review of argument-based ethics publications in 8 major databases of biomedical, philosophy, and theology literature that focused on relational autonomy in end-of-life care. Full articles were screened. All included articles were critically appraised, and a synthesis was produced.ResultsFifty publications met our inclusion criteria. Twenty-eight articles were published in the last 5 years; publications were originating from 18 different countries. Results are organized according to: (a) an individualistic interpretation of autonomy; (b) critiques of this individualistic interpretation of autonomy; (c) relational autonomy as theoretically conceptualised; (d) relational autonomy as applied to clinical practice and moral judgment in end-of-life situations.ConclusionsThree main conclusions were reached. First, literature on relational autonomy tends to be more a ‘reaction against’ an individualistic interpretation of autonomy rather than be a positive concept itself. Dichotomic thinking can be overcome by a deeper development of the philosophical foundations of autonomy. Second, relational autonomy is a rich and complex concept, formulated in complementary ways from different philosophical sources. New dialogue among traditionally divergent standpoints will clarify the meaning. Third, our analysis stresses the need for dialogical developments in decision making in end-of-life situations. Integration of these three elements will likely lead to a clearer conceptualisation of relational autonomy in end-of-life care ethics. This should in turn lead to better decision-making in real-life situations. (shrink)

The INBIOSA project brings together a group of experts across many disciplines who believe that science requires a revolutionary transformative step in order to address many of the vexing challenges presented by the world. It is INBIOSA’s purpose to enable the focused collaboration of an interdisciplinary community of original thinkers. This paper sets out the case for support for this effort. The focus of the transformative research program proposal is biology-centric. We admit that biology to date has been more fact-oriented (...) and less theoretical than physics. However, the key leverageable idea is that careful extension of the science of living systems can be more effectively applied to some of our most vexing modern problems than the prevailing scheme, derived from abstractions in physics. While these have some universal application and demonstrate computational advantages, they are not theoretically mandated for the living. A new set of mathematical abstractions derived from biology can now be similarly extended. This is made possible by leveraging new formal tools to understand abstraction and enable computability. [The latter has a much expanded meaning in our context from the one known and used in computer science and biology today, that is "by rote algorithmic means", since it is not known if a living system is computable in this sense (Mossio et al., 2009).] Two major challenges constitute the effort. The first challenge is to design an original general system of abstractions within the biological domain. The initial issue is descriptive leading to the explanatory. There has not yet been a serious formal examination of the abstractions of the biological domain. What is used today is an amalgam; much is inherited from physics (via the bridging abstractions of chemistry) and there are many new abstractions from advances in mathematics (incentivized by the need for more capable computational analyses). Interspersed are abstractions, concepts and underlying assumptions “native” to biology and distinct from the mechanical language of physics and computation as we know them. A pressing agenda should be to single out the most concrete and at the same time the most fundamental process-units in biology and to recruit them into the descriptive domain. Therefore, the first challenge is to build a coherent formal system of abstractions and operations that is truly native to living systems. Nothing will be thrown away, but many common methods will be philosophically recast, just as in physics relativity subsumed and reinterpreted Newtonian mechanics. -/- This step is required because we need a comprehensible, formal system to apply in many domains. Emphasis should be placed on the distinction between multi-perspective analysis and synthesis and on what could be the basic terms or tools needed. The second challenge is relatively simple: the actual application of this set of biology-centric ways and means to cross-disciplinary problems. In its early stages, this will seem to be a “new science”. This White Paper sets out the case of continuing support of Information and Communication Technology (ICT) for transformative research in biology and information processing centered on paradigm changes in the epistemological, ontological, mathematical and computational bases of the science of living systems. Today, curiously, living systems cannot be said to be anything more than dissipative structures organized internally by genetic information. There is not anything substantially different from abiotic systems other than the empirical nature of their robustness. We believe that there are other new and unique properties and patterns comprehensible at this bio-logical level. The report lays out a fundamental set of approaches to articulate these properties and patterns, and is composed as follows. -/- Sections 1 through 4 (preamble, introduction, motivation and major biomathematical problems) are incipient. Section 5 describes the issues affecting Integral Biomathics and Section 6 -- the aspects of the Grand Challenge we face with this project. Section 7 contemplates the effort to formalize a General Theory of Living Systems (GTLS) from what we have today. The goal is to have a formal system, equivalent to that which exists in the physics community. Here we define how to perceive the role of time in biology. Section 8 describes the initial efforts to apply this general theory of living systems in many domains, with special emphasis on crossdisciplinary problems and multiple domains spanning both “hard” and “soft” sciences. The expected result is a coherent collection of integrated mathematical techniques. Section 9 discusses the first two test cases, project proposals, of our approach. They are designed to demonstrate the ability of our approach to address “wicked problems” which span across physics, chemistry, biology, societies and societal dynamics. The solutions require integrated measurable results at multiple levels known as “grand challenges” to existing methods. Finally, Section 10 adheres to an appeal for action, advocating the necessity for further long-term support of the INBIOSA program. -/- The report is concluded with preliminary non-exclusive list of challenging research themes to address, as well as required administrative actions. The efforts described in the ten sections of this White Paper will proceed concurrently. Collectively, they describe a program that can be managed and measured as it progresses. (shrink)

Reseña del libro de Corine Pelluchon. Pour comprendre Levinas. Un philosophe pour notre temps. Paris: Seuil, 2020.

Epícteto, el filósofo estoico del siglo II de la e.c., nos presenta su visión ética en este discurso Sobre el embellecimiento . Se apoya en los preceptos socráticos del “Conócete a ti mismo” y “Cuídate a ti mismo”, pero los complementa maravillosamente con el “Ordénate a ti mismo”. Es una visión en la que la ética y la estética son embellecidas por la cosmética.
