Abstract We examine the construction of electromagnetism in its current form, and in an alternative form, from a point of view that combines a minimal realism with strict rational demands. We begin by discussing the requests of reason when constructing a theory and next, we follow the historical development as presented in the record of original publications, the underlying epistemology (often explained by the authors) and the mathematical constructions. The historical construction develops along socio-political disputes (mainly, the reunification of Germany (...) and the second industrial revolution), epistemic disputes (at least two demarcations of science in conflict) and several theories of electromagnetism. Such disputes resulted in the militant adoption of the ether by some, a position that expanded in parallel with the expansion of Prussia. This way of thinking was facilitated by the earlier adoption of a standpoint that required, as a condition for understanding, the use of physical hypothesis in the form of analogies; an attitude that is antithetic to Newton's “hypotheses non fingo”. While the material ether was finally abandoned, the epistemology survived in the form of “substantialism” and a metaphysical ether: the space. The militants of the ether attributed certainties regarding the ether to Faraday and Maxwell, when they only expressed doubts and curiosity. Thus, the official story is not the real history. This was achieved by the operation of detaching Maxwell's electromagnetism from its construction and introducing a new game of formulae and interpretations. Large and important parts of Maxwell work are today not known, as for example, the rules for the transformation of the electromagnetic potentials between moving systems. When experiments showed that all the theories based in the material ether were incorrect, a new interpretation was offered: Special Relativity (SR). At the end of the transformation period a pragmatic view of science, well adapted to the industrial society, had emerged, as well as a new protagonist: the theoretical physicist. The rival theory of delayed action at distance initiated under the influence of Gauss was forgotten in the midst of the intellectual warfare. The theory is indistinguishable in formulae from Maxwell's and its earlier versions are the departing point of Maxwell for the construction of his equations. We show in a mathematical appendix that such (relational) theory can incorporate Lorentz' contributions as well as Maxwell's transformations and C. Neumann's action, without resource to the ether. Demarcation criteria was further changed at the end of the period making room for habits and intuitions. When these intuited criteria are examined by critical reason (seeking for the fundaments) they can be sharpened with the use of the Non Arbitrariness Principle, which throws light over the arbitrariness in the construction of SR. Under a fully rational view SR is not acceptable, it requires to adopt a less demanding epistemology that detaches the concept from the conception, such as Einstein's own view in this respect, inherited from Hertz. In conclusion: we have shown in this relevant exercise how the reality we accept depends on earlier, irrational, decisions that are not offered for examination but rather are inherited from the culture.

La literatura de Kafka no es ciertamente complaciente, obliga al lector a releer una y otra vez. El sentido no está dado allí en el texto sino desplazado, porque la única manera que tiene de acontecer es en lo ausente, en lo inacabado. En diálogo con V. Karam, el presente artículo pretende recorrer parte de esa huella, intentando repensar allí la inasibilidad del tiempo, de la ley y de la interpretación.

A theory of knowledge is the explanation of things in terms of the possibilities and capabilities of the human way of knowing. The human knowledge is the representation of the things apprehended sensitively either through the senses or intuition. A theory of knowledge concludes about the reality of the things studied. As such it is a priori speculation, based on synthetic a priori statements. Its conclusions constitute interpretation, that is, hermeneutics. Linguistics as the science studying real language, that is, the (...) language spoken, reverts to human subjects in as much as they speak, say and know. Language thus must be studied as a theory of knowledge. (shrink)

The state of computing science and, particularly, software engineering and knowledge engineering is generally considered immature. The best starting point for achieving a mature engineering discipline is a solid scientific theory, and the primary reason behind the immaturity in these fields is precisely that computing science still has no such agreed upon underlying theory. As theories in other fields of science do, this paper formally establishes the fundamental elements and postulates making up a first attempt at a theory in this (...) field, considering the features and peculiarities of computing science. The fundamental elements of this approach are informons and holons, and it is a general and comprehensive theory of software engineering and knowledge engineering that related disciplines (e.g., information systems) can particularise and/or extend to take benefit from it (Lakatos’ concepts of core theory and protective belt theories).

Human beings make themselves with language in history. Language defines human beings making them subjects of their being and mode of being. In this sense language is essential and exclusive of humans. The problem with language consists in explaining the reality of language, something internal to speakers but manifesting itself as external to them.

Three Chilean Thinkers, a companion piece to Three Argentine Thinkers, attempts to examine some of the outstanding characters of Chile's intellectual development by way of analyzing the contribution of three of her distinguished representatives. Each thinker or philosopher, whichever the case may be, is symbolic of a definite sociopolitical movement which left its unmistakable imprint upon the cultural scene. Moreover, each thinker, no doubt, was strongly influenced by European philosophical trends, but should in now way be considered a mere imitator. (...) It would be more accurate to say that they adapted these currents to their particular situation, utilizing the various component elements in order to explain or reform the Spanish American scene. Since each of the three represents a separate epoch, it was thought best to present them in chronological fashion in order to insure a measure of historical continuity. Thus, the first author treated is Francisco Bilbao, representative par excellence of the Romantic period. He is followed by Valentín Letelier, who can be said to have been one of the foremost exponents of what may well be considered as a reaction to Romanticism, namely, the Positivist era. Finally, Positivism, in turn, also produced a reaction in the form of the various idealistic tendencies which blossomed forth at the turn of the century--reaction to the dominant position exercised by evolutionism and scientism--represented in Chile by Enrique Molina.

Resumen: El principal objetivo de este trabajo es pensar el concepto de meditación en la filosofía de Ortega y Gasset. La meditación es la esencia de la filosofía para Ortega. Meditar y filosofar son sinónimos. La filosofía no es mera teoría, sino que implica también práctica. El elemento teórico sólo tiene sentido cuando surge de la vida, pero ante todo la teoría sólo vale si vale para vivir. El ser humano para Ortega piensa porque vive, pero lo fundamental es que (...) piensa para vivir. Sólo los pensamientos que se alcanzan viviendo tienen valor para vivir. La meditación filosófica está siempre supeditada a la vida.The principal aim of this work is to think the concept of meditation in the Ortega y Gasset’s philosophy. For Ortega, meditation is the essence of philosophy. To meditate and to philosophize are synonymous. Philosophy isn’t simply theory, but it also implies practice. The theoretical element only makes sense when it arises from life, but above all theory only have value if it have value for life. For Ortega, human being thinks because he lives, but is fundamental that he thinks for life. Only thoughts reached by living have value for life. Philosophical meditation is always subordinated to life. (shrink)

ABSTRACT This paper compares the concept of the heart in the works of Max Scheler and María Zambrano. Both authors use the heart as a metaphor for distinct human affective phenomena that have a central anthropological, epistemological, and ontological significance. The comparison between authors’ use of the metaphor is organised around three main topics: the order of the heart; the idea of a primordial feeling and its place in the affective life; and the primacy of love in relation to negative (...) affective attitudes. Our aim is twofold: to investigate the influence of Scheler on Zambrano’s thought and to demonstrate how Scheler’s phenomenology of affectivity transformed in Spanish philosophy and, in particular, in Zambrano’s work. After introducing the topic, the paper focuses on Scheler’s model of affectivity, presents an overview of Scheler’s reception in Spain focusing on Zambrano’s knowledge of his works, and examines Zambrano’s notion of the heart tracing parallelisms in Scheler’s works. The paper concludes with a discussion on Zambrano’s extension and transformation of the metaphor of the heart in the context of Spanish philosophy. (shrink)
