We present a fully relational definition of inertial systems based in the No Arbitrariness Principle, that eliminates the need for absolute inertial frames of reference or distinguished reference systems as the ``fixed stars'' in order to formulate Newtonian mechanics. The historical roots of this approach to mechanics are discussed as well. The work is based in part in the constructivist perspective of space advanced by Piaget. We argue that inertial systems admit approximations and that what is of practical use are (...) precisely such approximations. We finally discuss a slightly larger class of systems that we call ``relatively inertial'' which are the fundamental systems in a relational view of mechanics. (shrink)

In the current secularization of religion nowadays, particularly of Christianity, we see that in the celebrations of the sacraments, specially Baptism and Eucharist, people are looking for something to give their lives sense, that they even don’t know for sure what is, but through the liturgical rites, expressed by the body language, try to make life in accordance with faith, even though still in a superficial way. Through the theology of the sacraments, theology of revelation and anthropology we realize that (...) the relationship between the human being and God is still very present and currently up-to-date, and not something "unknown" or even "lost". Thus, the human being is still seeking a close relationship with the Being who created him at His image and likeness that can be realized and manifested in liturgical celebrations, not forgetting the communal character of each liturgical act and its expressions.

Several countries have implemented COVID-19 health passes or certificates to promote a safer return to in-person social activities. These passes have been proposed as a way to prove that someone has been vaccinated, has recovered from the disease, or has negative results on a diagnostic test. However, many people have questioned their ethical justification. This article presents some practical and ethical problems to consider in the event of wishing to implement these passes. Among the former, it is questioned how accurate (...) diagnostic tests are as a means of ensuring that a person is not contagious, whether vaccination guarantees immunity, the fact that health passes can be forged, whether they encourage vaccination, and the problem that there is no universally recognized health pass. Among the ethical issues, it is discussed whether health passes promote discrimination and inequality and whether they violate rights to privacy and freedom. It is concluded that health passes have enough ethical justification to be implemented. (shrink)

In _Sociocybernetics and Political Theory in a Complex World_, Roberto Mancilla offers new takes on known ideas of political and constitutional theory; the advent of information technology and globalization puts them in crisis, as many stem from centuries past.

Proponemos una lectura de la obra de Hobbes como revolución, como ruptura radical con el pensamiento de la tradición dominante: ruptura, que lo es en casi todos los ámbitos, pero sobre todo en el del pensamiento político, moral y jurídico. Sugerimos, además, que esa radical ruptura sigue manteniendo elementos vivos y útiles para pensar la política hoy.

Resumen En el § 7 de la Crítica de la razón práctica Kant expone su primera definición de la ley moral universal. Ahí afirma que la conciencia de ella es un “Faktum de la razón”. La ambigüedad de esta expresión ha hecho que algunos autores argumenten que Kant no deduce la ley moral satisfactoriamente ni aclara cómo llegamos a ser conscientes de ella. Sin embargo estos críticos olvidan en sus análisis un aspecto relevante de la filosofía moral kantiana y que (...) es de gran relevancia en los estudios contemporáneos de la filosofía de la acción: el carácter autoconstitutivo del yo o del sujeto racional y su papel en la fundamentación de la moralidad. Sostengo que el Faktum de la razón debe entenderse fundamentalmente como un acto autoconstitutivo.In § 7 of the Critique of Practical Reason Kant presents his first definition of the universal law of morality - called the Categorical Imperative. In the same place, he affirms that being conscious of the law of morality is a Faktum of reason. The ambiguity of this statement has prompted some authors to argue that Kant does not deduce the moral law satisfactorily nor does he clarify how we become conscious of it. Nevertheless, they all forget in their analysis a relevant aspect of Kantian moral philosophy that turns out to be of great importance in contemporary studies of the philosophy of action - the self-constituting character of the rational subject and the role it plays within the foundation of morality. I claim that the Faktum of reason must be understood fundamentally as a self-constituting act. (shrink)

La presencia del orden se nos impone con singular insistencia. La reflexión sobre el orden, las posibilidades de su emergencia y las condiciones de su articulación y de su crítica, al igual que de su transgresión o transformación, ha constituido un eje central en el pensamiento filosófico y social continental a lo largo del siglo XX. Los trabajos que aparecen en este libro proceden de pensadores provenientes de Alemania, Francia y México y se proponen contribuir a una reflexión amplia, sistemática (...) y a la vez interdisciplinaria sobre este problema a la vez inquietante e inescapable.

En este artículo analizo los principales argumentos del libro Tauroética de Fernando Savater. Él afirma que existen argumentos morales a favor de las corridas de toros, por lo que ser taurino es una opción ética legítima. Aquí sostengo que está en un error y que los argumentos morales no tienen la fuerza que él les adjudica; puede haber razones económicas, políticas o de otro tipo a favor de las corridas, pero no hay razones morales. Afirmo, en cambio, que sí hay (...) razones morales fuertes en contra de las corridas que se basan en que los toros son objeto de consideración moral, es decir, tienen un estatus moral independiente de nuestros intereses. A partir de esta premisa examino y objeto, bajo una perspectiva ética, otros argumentos de Savater. (shrink)

This submission explores the concept of aesthetic justice pedagogy, and advocates on behalf of it. In contrast to aesthetic injustice, which denotes any harm done to a person’s aesthetic capacities, aesthetic justice pedagogy aims at facilitating the development of students’ imagination, perception, and feelings, wherein narrative and story-making are prime locations to contest coloniality and oppression. We emphasize the practice of this philosophy, refusing to see it as only as metaphor or theory. In our attempt to build a praxis of (...) philosophy, education, and art, we lean upon diverse thinkers such as Augusto Boal, John Dewey, Paulo Freire, and Ursula K. Le Guin. We maintain that aesthetic justice pedagogy requires spaces of liberation whereby initiates can practice, rehearse, and perform new realities and create counter-narratives through various modalities of story-writing. Boal’s Aesthetics of the Oppressed, Dewey’s understanding of dramatic rehearsal, Freire’s work in Culture Circles, and Le Guin’s critique of the father tongue combine art, re-storying, and imagination in ways that are unique to the traditional practices of arts education. We conclude by reemphasizing the liberatory ways in which practice (aesthetic work that is done alone), rehearsal (art work with others), and performance (imagination’s accomplishment) come to identify unique qualities and practices of an aesthetic justice pedagogy.

En este ensayo discuto si deberíamos entender la objetividad que predicamos de juicios evaluativos en los mismos términos en que lo hacemos de juicios epistémicos. Argumento a favor de un entendimiento de dominio específico de la objetividad, según el cual deberíamos ver a la verdad como central para la objetividad epistémica, pero no para la objetividad evaluativa. Sin embargo, esta posición tradicionalmente ha conducido a ver los juicios evaluativos como subjetivos. Aquí argumento que la carencia de valores de verdad no (...) necesariamente conduce al subjetivismo; no, si no se conciben los juicios evaluativos como expresiones de sentimientos o deseos sin ninguna restricción racional. Más que en el concepto de verdad, en el caso de la objetividad de juicios evaluativos, el énfasis debe ponerse en el de justificación. Sin embargo, este concepto por sí solo no es garante de objetividad (del mismo modo en que tampoco lo es el de verdad). Trato de ahondar en algunas de las condiciones para predicar objetividad de juicios evaluativos y para ello también distingo entre tipos de objetividad. (shrink)

The global emergency caused by the spread of COVID-19 raises critical challenges for individuals and communities on many different levels. In particular, politicians, scientists, physicians, and other professionals may face new ethical dilemmas and cognitive constraints as they make critical decisions in extraordinary circumstances. Philosophers and cognitive scientists have long analyzed and discussed such issues. An example is the debate on moral decision making in imaginary scenarios, such as the famous “Trolley Problem”. Similarly, dramatic and consequential decisions are realized daily (...) in the current crisis. Focusing on Italy, we discuss the clinical ethical guidelines proposed by the Italian Society of Anesthesiology, Analgesia, Resuscitation and Intensive Care, highlighting some crucial ethical and cognitive concerns surrounding emergency decision making in the current situation.

Un vínculo necesario entre estética y socialización explica la profundidad sensible que debe construir todo cambio de paradigma y toda re-socialización. La democracia no funciona sin una apropiación individual y colectiva del sentir y de la producción de sentir. Es a partir entonces del trabajo artístico y de la instrospección y exteriorización de la dimensión sensible, que toda transformación puede ser aplicada. Se recorren parcialmente los pensamientos de Alain Badiou y Bernard Stiegler. A required link between aesthetic and socialization explains (...) the sensitive depth that all paradigm and re-socialization must build. Democracy does not work without an individual and collective ownership of feeling and feeling's production. It is from the artwork and the introspection and externalization of the sensitive dimension, that any transformation can be applied. The article covers partially the thoughts of Alain Badiou and Bernard Stiegler. (shrink)

In this paper I argue that the way in which we revise and change our beliefs is different from that in which we revise and change our judgments of value; this is due to the fact that judgments of value, unlike beliefs, have no truth-values. Changes of judgments of value do not answer in the same way to the restrictions that apply to changes of beliefs and that are determined by the norms that govern beliefs. I argue that, first when (...) we revise and change our beliefs, we should be in a position to suspend judgments, and when trying to remove doubts, we should try to avoid falsehood and, second when changing beliefs, we should be in a position to assign probabilities to those conjectures we are in suspense about. These two conditions apply to the case of changes of attitudes with truth-values, such as beliefs; I argue that these two characteristics do not apply to cases of changes of judgments of value.Neste artigo eu argumento que o modo pelo qual nós revisamos e mudamos nossas crenças é diferente daquele pelo qual revisamos e mudamos nossos juízos de valor; isto se dá porque juízos de valor, ao contrário de crenças, não possuem nenhum valor de verdade. Mudanças de juízos de valor não estão sujeitas às mesmas restrições que se aplicam às mudanças de crenças e que são determinadas pelas normas que governam estas. Eu argumento que, primeiro, quando revisamos e mudamos nossas crenças, nós deveríamos ser capazes de suspender juízos e, ao tentarmos suprimir dúvidas, deveríamos tentar evitar a falsidade e, segundo, ao mudarmos as crenças, nós deveríamos ser capazes de atribuir probabilidades àquelas conjecturas sobre as quais nós estamos em dúvida. Estas duas condições se aplicam aos casos de mudanças de atitudes com valores de verdade, tais como crenças; eu argumento que estas duas características não se aplicam aos casos de mudanças de juízos de valor.

ABSTRACT In the 1960s, when Dr. Belding Scribner discovered how to accomplish the process of dialysis in a repeated way, he could not imagine that in solving such a problem others as or more difficult would appear. Given the technological progress and the impossibility of assisting all patients through the most modern methods, the medical doctor often finds himself faced with the moral dilemma of choosing which patient in the waiting list will receive the treatment. This same dilemma is amplified (...) in the case of organ transplants. Professionals, students, professors of the juridical and health fields, and the population in general, were interviewed as a means of documenting the moral concepts and opinions surrounding this problem. In the reality in which we find ourselves, it seems to us that deciding who lives, and the responsibility for all the events that culminate in such decisions, is still a subject left open to discussion.

Some initial considerations on film in documentary form are discussed, along with its relationships with reality and fiction in cinema language. Found footage genre is explained, pointing its most important technical and aesthetical characteristics. The text points the importance of the movie camera in documentary and found footage, not only as a technical device that objectivizes the information in a static manner, but also as an axis that configures dynamism and subjectivity on films. Redacted (2007) by Brian De Palma is (...) analyzed as an example of hybrid forms of fiction and reality in cinema. Beyond a traditional analysis of narrative of films, this text emphasizes the forms in which they are developed, which affect and determine the substance of films. (shrink)

We present a theory VF of partial truth over Peano arithmetic and we prove that VF and ID 1 have the same arithmetical content. The semantics of VF is inspired by van Fraassen's notion of supervaluation.

We investigate a contractionless naive set theory, due to Grisin [11]. We prove that the theory is undecidable.

This textbook presents the basics of philosophy that are necessary for the student and researcher in science in order to better understand scientific work. The approach is not historical but formative: tools for semantical analysis, ontology of science, epistemology, and scientific ethics are presented in a formal and direct way. The book has two parts: one with the general theory and a second part with application to some problems such as the interpretation of quantum mechanics, the nature of mathematics, and (...) the ontology of spacetime. The book addresses questions such as "What is meaning?", "What is truth?", "What are truth criteria in science?", "What is a theory?", "What is a model?" "What is a datum?", "What is information?", "What does it mean to understand something?", "What is space?", "What is time?", "How are these concepts articulated in science?" "What are values?" "What are the limits of science?", and many more. The philosophical views presented are "scientific" in the sense that they are informed by current science, they are relevant for scientific research, and the method adopted uses the hypothetical-deductive approach that is characteristic of science. The results and conclusions, as any scientific conclusion, are open to revision in the light of future advances. Hence, this philosophical approach opposes to dogmatic philosophy. Supported by end-of-chapter summaries and a list of special symbols used, the material will be of interest for students and researchers in both science and philosophy. The second part will appeal to physicists and mathematicians. (shrink)

We give a new elementary proof of the comparison theorem relating $\sum^1_{n + 1}-\mathrm{AC}\uparrow$ and $\Pi^1_n -\mathrm{CA}\uparrow$ ; the proof does not use Skolem theories. By the same method we prove: a) $\sum^1_{n + 1}-\mathrm{DC} \uparrow \equiv (\Pi^1_n -CA)_{ , for suitable classes of sentences; b) $\sum^1_{n+1}-DC \uparrow$ proves the consistency of (Π 1 n -CA) ω k, for finite k, and hence is stronger than $\sum^1_{n+1}-AC \uparrow$ . a) and b) answer a question of Feferman and Sieg.

We introduce a notion of semantical closure for theories by formalizing Nepeivoda notion of truth. [10]. Tarski theorem on truth definitions is discussed in the light of Kleene's three valued logic (here treated with a formal reinterpretation of logical constants). Connections with Definability Theory are also established.

We introduce an operational set theory in the style of [5] and [16]. The theory we develop here is a theory of constructive sets and operations. One motivation behind constructive operational set theory is to merge a constructive notion of set ([1], [2]) with some aspects which are typical of explicit mathematics [14]. In particular, one has non-extensional operations (or rules) alongside extensional constructive sets. Operations are in general partial and a limited form of self{application is permitted. The system we (...) introduce here is a fully explicit, nitely axiomatised system of constructive sets and operations, which is shown to be as strong as HA. (shrink)
