Este artículo se halla dividido en tres partes.En la primera, se define el estado de la ciencia física y del positivismo lógico, concluyendo el tránsito de ambos hacia el constructivismo.En la segunda, se realiza un esbozo del constructivismo de Piaget.Finalmente, en el tercer apartado, con la intención de desarrollar un ejemplo de esta confluencia en las ciencias sociales,se constata que ciertos criterios de validez defendidos para la metodología cualitativa se complementan totalmente con los contenidos en la estadística .This article is (...) divided into three sections. First, we define the state of physical science and logical positivism, concluding the transit of both towards constructivism. Second, we outlined the Piaget constructivism. Third, with the intention of developing an example of this confluence in social sciences, we argue that few criteria of qualitative methodology validity are completely complementary to those contained in the statistics.

This paper is concerned with formal aspects of the logic of theory change, and in particular with the process of shrinking or contracting a theory to eliminate a proposition. It continues work in the area by the authors and Peter Gärdenfors. The paper defines a notion of safe contraction of a set of propositions, shows that it satisfies the Gärdenfors postulates for contraction and thus can be represented as a partial meet contraction, and studies its properties both in general and (...) under various natural constraints.

In some recent papers, the authors and Peter Gärdenfors have defined and studied two different kinds of formal operation, conceived as possible representations of the intuitive process of contracting a theory to eliminate a proposition. These are partial meet contraction (including as limiting cases full meet contraction and maxichoice contraction) and safe contraction. It is known, via the representation theorem for the former, that every safe contraction operation over a theory is a partial meet contraction over that theory. The purpose (...) of the present paper is to study the relationship more finely, by seeking an explicit map between the component orderings involved in each of the two kinds of contraction. It is shown that at least in the finite case a suitable map exists, with the consequence that the relational, transitively relational, and antisymmetrically relational partial meet contraction functions form identifiable subclasses of the safe contraction functions, over any theory finite modulo logical equivalence. In the process of constructing the map, as the composition of four simple transformations, mediating notions of bottom and top contraction are introduced. The study of the infinite case remains open.

William Parry conceived in the early thirties a theory of entail-
ment, the theory of analytic implication, intended to give a formal expression to the idea that the content of the conclusion of a valid argument must be included in the content of its premises. This paper introduces a system of analytic, paraconsistent and quasi-classical propositional logic that does not validate the paradoxes of Parry’s analytic implication. The interpretation of the expressions of this logic will be given in terms of a (...) four-valued semantics,and its proof theory will be provided by a system of signed semantic tableaux that incorporates the techniques developed to improve the efficiency of the tableaux method for many-valued logics.

The purpose of the paper is to present a logical framework that allow to formalize a kind of prima facie duties, defeasible conditional duties, indefeasible conditional duties and actual (indefeasible) duties, as well as to show their logical interconnections.

: "We are invisible": this melancholic assertion alludes to the "non-place" that we occupy as Latin American philosophers or, in general, as philosophers in the Spanish or Portuguese languages. We tend to survive as mere ghosts teaching courses and writing texts, perhaps some memorable ones, which, however, seldom spark anybody's interest, among other reasons, because almost no one takes the time to read them. In saying this, I do not mean to call upon a useless pathos, nor do I mean (...) to complain, or thrust forth a challenge. I am simply confirming a fact, and a widely acknowledged one at that. I wish to inquire a little into this invisibility. Later I will look into how the experience of our much acclaimed essay may help in fighting it. (shrink)

In this paper we show the embedding of Hybrid Probabilistic Logic Programs into the rather general framework of Residuated Logic Programs, where the main results of (definite) logic programming are validly extrapolated, namely the extension of the immediate consequences operator of van Emden and Kowalski. The importance of this result is that for the first time a framework encompassing several quite distinct logic programming semantics is described, namely Generalized Annotated Logic Programs, Fuzzy Logic Programming, Hybrid Probabilistic Logic Programs, and Possibilistic (...) Logic Programming. Moreover, the embedding provides a more general semantical structure paving the way for defining paraconsistent probabilistic reasoning with a logic programming semantics.

Having a “normal” professional job and doing research impose different social and personal connotations. These differences materialize at least in two clear ways. First, it is common that researchers in the making find it very difficult to communicate to their closest social network (e.g., family and old close friends) the content and the importance of their work, as they lose known sources of social comparison. Meanwhile, professional job titles (e.g., brand manager, auditor, lawyer) are self-explanatory, and they provide for the (...) owner an immediate social contextualization and recognition. Second, students normally receive delayed and ambiguous feedback and reinforcement while doing a PhD, contrasting with the continuous flow of assessment that companies give to their employees. In this article, I analyze how young researchers may develop a feeling of social isolation as the communication bridges with family, old friends, and undergraduate colleagues become narrower than before, making it difficult to receive external reinforcement on their social position and comparative achievement. This feeling, combined with the ambiguous feedback during the early stages of a research career, challenges the self-esteem of PhD students, forcing them to develop a self-contained personal security in order to cope with those two social contexts. Some young researchers might even withdraw from PhD programs should they fail to develop such psychological strength. I approach the issue through my own experience, first as a junior consultant in a multinational firm and then as a PhD candidate in economics. Second, I explore the behavioral phenomena that occur beneath those feelings in order to understand how to build such psychological strength. My goal is, through the exploration of my personal experience of becoming a researcher, to offer young researchers a useful narrative to help face the potentially negative feelings that may emerge when learning to balance these conflicting social roles.

Resumen: Varios comentaristas han sostenido que la ontología de la concepción hegeliana de “alma bella” se funda en la determinación conocida como “mal infinito”, desarrollada en la Doctrina del Ser. En correlación con lo antedicho, comentaristas como Paha, Hinchman, Solomon y Harris sostienen que Hegel pensaba en el sistema filosófico fichteano al momento de desarrollar su concepción de “alma bella”. Sin embargo, esta hipótesis de lectura adolece de algunas falencias que serán desarrolladas a continuación. En primer lugar, es necesario realizar (...) una breve exposición de la figura del Espíritu conocida como “alma bella”; en segundo lugar, se describirá la determinación denominada “mal infinito”; en tercer lugar, se desarrollarán los problemas que conlleva la mencionada exégesis; en cuarto lugar, se expondrán las objeciones a la inclusión de la filosofía de Fichte como ejemplo de la concepción hegeliana de “alma bella”. Finalmente, se expondrán las conclusiones.: Many scholars have stated that the ontology of the Hegelian notion of “beautiful soul” is grounded in the category known as “bad infinite”, developed in the Doctrine of Being. Regarding this, scholars like Paha, Hinchman, Solomon and Harris state that Hegel was thinking of the Fichtean philosophical system as He developed his own notion of “beautiful soul”. However, this interpretation has some issues, which will be developed below. First, we give a short explanation about the shape of the Spirit known as “beautiful soul”. Second, we describe the category called “bad infinite”. Third, we show the issues related to the interpretation. Fourth, we present the objections to the inclusion of the Fichtean philosophy as an example of the Hegelian notion of “beautiful soul”. Finally, we present the conclusions. (shrink)

Después de varios años e investigaciones sobre la educación y el nuevo paradigma científico hemos llegado a comprender que los gérmenes caóticos de la educación y la desescolarización están presentes en el día a día escolar, aunque ocultos, si no negados, por la cultura escolar. Debemos sacarlos a la luz y comprender su potencialidad e influencia educativa transformadora. Por muchos años buscábamos que la desescolarización de la escuela no implicara su eliminación, tal como lo propuso Illich ..

En este artículo el autor se propone analizar la posición de Davidson respecto de la verdad como correspondencia a lo largo de su obra. Pueden establecerse dos períodos en su obra, un primero que va desde sus trabajos iniciales hasta sus “Afterthoughts” de 1987 y un segundo que va desde esa fecha hasta sus últimos trabajos. Lo que caracteriza a esos períodos es que durante el primero Davidson se proclama correspondentista, en el segundo se arrepiente de haber adoptado esa denominación, (...) a lo cual caracteriza como un error terminológico. La intención del autor aquí es considerar cuál puede haber sido la razón para dicho error terminológico y cuánto de la aceptación de algo como la correspondencia persiste en los trabajos posteriores de Davidson. Se propone para ello establecer una distinción entre dos modos en que debe entenderse la correspondencia, que se encuentran emparentados con dos modos de entender el análisis filosófico y con lo que Wright llama el debate tradicionalacerca de la verdad, y el nuevo giro que el mismo debería tomar.

Ancient monism matters today because it reveals an alternative answer to a problem faced by ontology “after the death of god,” namely, how to distinguish between good and bad actions after the disappearance of transcendence. The modern answer in Continental philosophy was systematized by Heidegger and consists in positing that the everyday is permeated by instrumentality whereas there is a different kind of action that is noninstrumental, such as art or the thinking of being. By contrast, ancient monism holds that (...) all actions are instrumental and employs on a typology of action that relies on the distinction between techne and phronesis. Recognizing a different answer from the dominant Heideggerian one has the potential to renew the conception of the ethical and the political in Continental philosophy. (shrink)

This paper deals with the relationship between divine knowledge and sense experience and the first three Thomistic ways to prove the existence of God. It reinforces the ways in the light of contributions and critiques coming from the realist-phenomenological and the analytic perspectives. To this end, it examines the insights of an important author of each of these two traditions, Josef Seifert and Richard Swinburne.

Resumo: O artigo apresenta um problema que se apresenta no tempo presente e que nos coloca diante da tarefa de repensar os paradigmas da educação e do pensamento. O texto questiona qual o impacto da globalização em como pensamos a Educação e a Filosofia. A base epistemológica do artigo se ancora no pensamento da desconstrução e nas suas interseções com o debate sobre políticas das diferenças e seu desenrolar em autores como Achille Mbembe, Louis Althusser, Frantz Fanon, Lélia Gonzales, Jean-Luc (...) Nancy, entre outros. No artigo apresentamos o conflito entre o mundo ocidental e seu pensamento único com a reflexão de autores que trazem aquilo que excede a este pensamento e que é marginalizado por ele. Colocamos em debate e relação conceitos como brutalismo, raça, desconstrução, ideologia, antropoceno etc. Palavras-chave: Desconstrução; Pedagogia; Filosofia da Diferença; Decolonialidade; Globalização. Education in the face of the end of the World and the end of Philosophy: Brutalism, deconstruction and some reflections on decoloniality, anti-racism and their intersections Abstract: The article presents a problem that arises in the present time and that puts us before the task of rethinking the paradigms of education and thought. The text questions the impact of globalization on how we think about Education and Philosophy. The epistemological basis of the article is anchored in the thought of deconstruction and its intersections with the debate on the politics of differences and its revelation in authors such as Achille Mbembe, Louis Althusser, Frantz Fanon, Lélia Gonzales, Jean-Luc Nancy, among others. The article presents the conflict between the Western world and its monolithic thought with the reflection of authors who bring what exceeds this thought and is marginalized by it. We put into debate and relationships such as brutalism, race, deconstruction, ideology, anthropocene, etc. Keywords: Deconstruction; Pedagogy; Philosophy of Difference; Decoloniality; Globalization.

Este artigo pretende apresentar a diferença entre a hermenêutica e a desconstrução e mostrar a implicação de cada uma destas formas de entender o fenômeno do sentido na relação da filosofia com as outras “disciplinas” do pensamento. Para isso colocaremos dois pensadores em embate direto, a saber, Jacques Derrida e Paul Ricoeur. Enquanto Paul Ricoeur, com seu projeto hermenêutico, tenta encontrar uma conciliação entre os diversos saberes das ciências humanas com a metafísica, em uma época em que o estruturalismo e (...) a psicanálise emergiam e questionavam conceitos como “consciência” e “sentido”, Jacques Derrida radicaliza esses movimentos de crítica que animavam as ciências humanas e tenta pensar para além dos conceitos tradicionais, propondo seus quaseconceitos e formulando sua gramatologia.

This paper analyzes the problem of rational justification of law in general and legal norms in particular, a problem highlighted by the so-called postmodern trends that deny the possibility and validity of these attempts. While the postmodern trends serve as a background to the discussion, the article provides a summary of rational justification of norms based on Sergio Cotta’s innovative approach, who is arguably one of the authors that has dealt to the topic with more prominence and consistency. Thus, the (...) goal of this article is to point out how the election of a norm can be justified, and to explain the main notions of Cotta’s approach, in order to assess his accuracy and weakness, and his connection to the theory of practical knowledge. The article concludes with some remarks on Cotta’s justification model.Resumen:El presente artículo desarrolla el problema de la justificación racional del derecho en general y de las normas jurídicas en particular, ante las corrientes de pensamiento denominadas posmodernas que niegan la posibilidad y validez de tales intentos. El trabajo ofrece una reseña acerca de la justificación racional de las normas a partir de la novedosa doctrina de Sergio Cotta, quien es uno de los autores que ha abordado el tema con mayor extensión y consistencia. A lo largo del artículo, el autor intenta mostrar de qué manera está fundada la elección de una norma, explica las nociones centrales de la doctrina de Cotta, identifica sus aciertos, sus debilidades, su conexión con la teoría del conocimiento práctico y concluye con algunas observaciones al modelo de justificación propuesto.

Lukács and Twentieth Century Literature Tough he elaborated a robust system of Marxist aesthetics whose categories enabled him to formulate a brilliant analysis of the 19th century realist novel, Lukács proved unable to understand the literature of the 20th century. In fact he either ignored or regarded as “decadent” almost all the major representatives of the avant-garde, such as Proust and Kafka. is was not due to the intrinsic limitations of the aesthetic categories themselves. It was rather an effect of (...) his “optimistic” vision of the historical period following after the 1917 Revolution and the hypothesis of the development of socialism. is led him to regard as anti-realist the alleged “pessimism” of the avant-garde. Towards the end of his life, Lukács did however adopt a more critical position towards “real socialism”. He thus moved towards a more positive understanding of the literature of his time. (shrink)

Even though residuation is at the core of Categorial Grammar (Lambek, 1958), it is not always immediate to realize how standard logical systems like Multi-modal Categorial Type Logics (MCTL) (Moortgat, 1997) actually embody this property. In this paper, we focus on the basic system NL (Lambek, 1961) and its extension with unary modalities NL() (Moortgat, 1996), and we spell things out by means of Display Calculi (DC) (Belnap, 1982; Goré, 1998). The use of structural operators in DC permits a sharp (...) distinction between the core properties we want to impose on the logical system and the way these properties are projected into the logical operators. We will show how we can obtain Lambek residuated triple \, / and of binary operators, and how the operators and introduced by Moortgat (1996) are indeed their unary counterpart.In the second part of the paper we turn to other important algebraic properties which are usually investigated in conjunction with residuation (Birkhoff, 1967): Galois and dual Galois connections. Again, DC let us readily define logical calculi capturing them. We also provide preliminary ideas on how to use these new operators when modeling linguistic phenomena. (shrink)
