Educação e sustentabilidade: relações possíveis

Considering the defi nition of Environmental Education as a human development process that seeks the transformation of the relationship between society and environment, this paper – collectively written by the members of the research group – discusses the theoretical framework of our studies, understanding them not as ’straitjackets’ that force us to repeat and reproduce predetermined analysis, but as a pathway, a method to interpret reality, a method to look for the essence of the studied phenomena, the real world. The theoretical framework we present helps us, therefore, to overcome the fragmented feature of the construction of knowledge proposed by methodologies in whose epistemological axis are located empiricism, positivism and idealism, as well as to fi nd out the laws of the phenomena whose study concerns us. It also helps us to capture in detail the details of the problems, to analyze their evolution and track the connections between phenomena that surround them. That is the Historical, Dialectical and Materialistic method formulated by Marx and those who came after him, also known as the philosophy of praxis. Based on this reference, we discuss here the relationship between environmental education and sustainability, bringing the concepts of sustainable development and sustainability into the debate, concluding that for the critical perspective explained here, environmental education for sustainability is a process that joins theory and practice for the transformation of the relationships between societies and the environment. This is the critical dimension of environmental education as we comprehend it.

Characterization of multiple reflections and phase space properties for a periodically corrugated waveguide

Dynamical properties for a beam light inside a sinusoidally corrugated waveguide are discussed in this paper. The beam is confined inside two-mirrors: one is flat and the other one is sinusoidally corrugated. The evolution of the system is described by the use of a two-dimensional and nonlinear mapping. The phase space of the system is of mixed type therefore exhibiting a large chaotic sea, periodic islands and invariant KAM curves. A careful discussion of the numerical method to solve the transcendental equations of the mapping is given. We characterize the probability of observing successive reflections of the light by the corrugated mirror and show that it is scaling invariant with respect to the amplitude of the corrugation. Average properties of the chaotic sea are also described by the use of scaling arguments.

O capital portador de juros em O Capital ou o sistema de Marx

O presente artigo busca estabelecer o local e a função do capital portador de juros em O Capital, visando com isso jogar luz sobre a estrutura eminentemente sistemática desta obra. Deste modo a obra máxima de Marx aparecerá muito próxima do idealismo alemão (particularmente de Fichte e Hegel), onde a questão da sistematicidade (da filosofia) foi sentida de maneira mais premente.

Rafael Moneo: la complessità del vuoto. Dalle matrici formali dell'opera di Oteiza e Chillida

The experience of void, essential to the production of forms and to make use them, can be considered as the base of the activities that attend to the formative processes. If void and matter constitutes the basic substances of architecture. Their role in the definition of form, the symbolic value and the constructive methods of it defines the quality of the space. This job inquires the character of space in the architecture of Moneo interpreting the meaning of the void in the Basque culture through the reading of the form matrices in the work of Jorge Oteiza and Eduardo Chillida. In the tie with the Basque culture a reading key is characterized by concurring to put in relation some of the theoretical principles expressed by Moneo on the relationship between place and time, in an unique and specific vision of the space. In the analysis of the process that determines the genesis of the architecture of Moneo emerges a trajectory whose direction is constructed on two pivos: on the one hand architecture like instrument of appropriation of the place, gushed from an acquaintance process who leans itself to the reading of the relations that define the place and of the resonances through which measuring it, on the other hand the architecture whose character is able to represent and to extend the time in which he is conceived, through the autonomy that is conferred to them from values. Following the trace characterized from this hypothesis, that is supported on the theories elaborated from Moneo, surveying deepens the reading of the principles that construct the sculptural work of Oteiza and Chillida, features from a search around the topic of the void and to its expression through the form. It is instrumental to the definition of a specific area that concurs to interpret the character of the space subtended to a vision of the place and the time, affine to the sensibility of Moneo and in some way not stranger to its cultural formation. The years of the academic formation, during which Moneo enters in contact with the Basque artistic culture, seem to be an important period in the birth of that knowledge that will leads him to the formulation of theories tied to the relationship between time, place and architecture. The values expressed through the experimental work of Oteiza and Chillida during years '50 are valid bases to the understanding of such relationships. In tracing a profile of the figures of Oteiza and Chillida, without the pretension that it is exhaustive for the reading of the complex historical period in which they are placed, but with the needs to put the work in a context, I want to be evidenced the important role carried out from the two artists from the Basque cultural area within which Moneo moves its first steps. The tie that approaches Moneo to the Basque culture following the personal trajectory of the formative experience interlaces to that one of important figures of the art and the Spanish architecture. One of the more meaningful relationships is born just during the years of his academic formation, from 1958 to the 1961, when he works like student in the professional office of the architect Francisco Sáenz de Oiza, who was teaching architectural design at the ETSAM. In these years many figures of Basque artists alternated at the professional office of Oiza that enjoys the important support of the manufacturer and maecenas Juan Huarte Beaumont, introduced to he from Oteiza. The tie between Huarte and Oteiza is solid and continuous in the years and it realizes in a contribution to many of the initiatives that makes of Oteiza a forwarder of the Basque culture. In the four years of collaboration with Oiza, Moneo has the opportunity to keep in contact with an atmosphere permeated by a constant search in the field of the plastic art and with figures directly connected to such atmosphere. It’s of a period of great intensity as in the production like in the promotion of the Basque art. The collective “Blanco y Negro”, than is held in 1959 at the Galería Darro to Madrid, is only one of the many times of an exhibition of the work of Oteiza and Chillida. The end of the Fifties is a period of international acknowledgment for Chillida that for Oteiza. The decade of the Fifties consecrates the hypotheses of a mythical past of the Basque people through the spread of the studies carried out in the antecedent years. The archaeological discoveries that join to a context already rich of signs of the prehistoric era, consolidate the knowledge of a strong cultural identity. Oteiza, like Chillida and other contemporary artists, believe in a cosmogonist conception belonging to the Basques, connected to their matriarchal mythological past. The void in its meaning of absence, in the Basque culture, thus as in various archaic and oriental religions, is equivalent to the spiritual fullness as essential condition to the revealing of essence. Retracing the archaic origins of the Basque culture emerges the deep meaning that the void assumes as key element in the religious interpretation of the passage from the life to the death. The symbology becomes rich of meaningful characters who derive from the fact that it is a chthonic cult. A representation of earth like place in which divine manifest itself but also like connection between divine and human, and this manipulation of the matter of which the earth it is composed is the tangible projection of the continuous search of the man towards God. The search of equilibrium between empty and full, that characterizes also the development of the form in architecture, in the Basque culture assumes therefore a peculiar value that returns like constant in great part of the plastic expressions, than in this context seem to be privileged regarding the other expressive forms. Oteiza and Chillida develop two original points of view in the representation of the void through the form. Both use of rigorous systems of rules sensitive to the physics principles and the characters of the matter. The last aim of the Oteiza’s construction is the void like limit of the knowledge, like border between known and unknown. It doesn’t means to reduce the sculptural object to an only allusive dimension because the void as physical and spiritual power is an active void, that possesses that value able to reveal the being through the trace of un-being. The void in its transcendental manifestation acts at the same time from universal and from particular, like in the atomic structure of the matter, in which on one side it constitutes the inner structure of every atom and on the other one it is necessary condition to the interaction between all the atoms. The void can be seen therefore as the action field that concurs the relations between the forms but is also the necessary condition to the same existence of the form. In the construction of Chillida the void represents that counterpart structuring the matter, inborn in it, the element in absence of which wouldn’t be variations neither distinctive characters to define the phenomenal variety of the world. The physics laws become the subject of the sculptural representation, the void are the instrument that concurs to catch up the equilibrium. Chillida dedicate himself to experience the space through the senses, to perceive of the qualities, to tell the physics laws which forge the matter in the form and the form arranges the places. From the artistic experience of the two sculptors they can be transposed, to the architectonic work of Moneo, those matrices on which they have constructed their original lyric expressions, where the void is absolute protagonist. An ambit is defined thus within which the matrices form them drafts from the work of Oteiza and Chillida can be traced in the definition of the process of birth and construction of the architecture of Moneo, but also in the relation that the architecture establishes with the place and in the time. The void becomes instrument to read the space constructed in its relationships that determine the proportions, rhythms, and relations. In this way the void concurs to interpret the architectonic space and to read the value of it, the quality of the spaces constructing it. This because it’s like an instrument of the composition, whose role is to maintain to the separation between the elements putting in evidence the field of relations. The void is that instrument that serves to characterize the elements that are with in the composition, related between each other, but distinguished. The meaning of the void therefore pushes the interpretation of the architectonic composition on the game of the relations between the elements that, independent and distinguished, strengthen themselves in their identity. On the one hand if void, as measurable reality, concurs all the dimensional changes quantifying the relationships between the parts, on the other hand its dialectic connotation concurs to search the equilibrium that regulated such variations. Equilibrium that therefore does not represent an obtained state applying criteria setting up from arbitrary rules but that depends from the intimate nature of the matter and its embodiment in the form. The production of a form, or a formal system that can be finalized to the construction of a building, is indissolubly tied to the technique that is based on the acquaintance of the formal vocation of the matter, and what it also can representing, meaning, expresses itself in characterizing the site. For Moneo, in fact, the space defined from the architecture is above all a site, because the essence of the site is based on the construction. When Moneo speaks about “birth of the idea of plan” like essential moment in the construction process of the architecture, it refers to a process whose complexity cannot be born other than from a deepened acquaintance of the site that leads to the comprehension of its specificity. Specificity arise from the infinite sum of relations, than for Moneo is the story of the oneness of a site, of its history, of the cultural identity and of the dimensional characters that that they are tied to it beyond that to the physical characteristics of the site. This vision is leaned to a solid made physical structure of perceptions, of distances, guideline and references that then make that the process is first of all acquaintance, appropriation. Appropriation that however does not happen for directed consequence because does not exist a relationship of cause and effect between place and architecture, thus as an univocal and exclusive way does not exist to arrive to a representation of an idea. An approach that, through the construction of the place where the architecture acquires its being, searches an expression of its sense of the truth. The proposal of a distinction for areas like space, matter, spirit and time, answering to the issues that scan the topics of the planning search of Moneo, concurs a more immediate reading of the systems subtended to the composition principles, through which is related the recurrent architectonic elements in its planning dictionary. From the dialectic between the opposites that is expressed in the duality of the form, through the definition of a complex element that can mediate between inside and outside as a real system of exchange, Moneo experiences the form development of the building deepening the relations that the volume establishes in the site. From time to time the invention of a system used to answer to the needs of the program and to resolve the dual character of the construction in an only gesture, involves a deep acquaintance of the professional practice. The technical aspect is the essential support to which the construction of the system is indissolubly tied. What therefore arouses interest is the search of the criteria and the way to construct that can reveal essential aspects of the being of the things. The constructive process demands, in fact, the acquaintance of the formative properties of the matter. Property from which the reflections gush on the relations that can be born around the architecture through the resonance produced from the forms. The void, in fact, through the form is in a position to constructing the site establishing a reciprocity relation. A reciprocity that is determined in the game between empty and full and of the forms between each other, regarding around, but also with regard to the subjective experience. The construction of a background used to amplify what is arranged on it and to clearly show the relations between the parts and at the same time able to tie itself with around opening the space of the vision, is a system that in the architecture of Moneo has one of its more effective applications in the use of the platform used like architectonic element. The spiritual force of this architectonic gesture is in the ability to define a place whose projecting intention is perceived and shared with who experience and has lived like some instrument to contact the cosmic forces, in a delicate process that lead to the equilibrium with them, but in completely physical way. The principles subtended to the construction of the form taken from the study of the void and the relations that it concurs, lead to express human values in the construction of the site. The validity of these principles however is tested from the time. The time is what Moneo considers as filter that every architecture is subordinate to and the survival of architecture, or any of its formal characters, reveals them the validity of the principles that have determined it. It manifests thus, in the tie between the spatial and spiritual dimension, between the material and the worldly dimension, the state of necessity that leads, in the construction of the architecture, to establish a contact with the forces of the universe and the intimate world, through a process that translate that necessity in elaboration of a formal system.

Dielectric relaxation in biological materials

The study of dielectric properties concerns storage and dissipation of electric and magnetic energy in materials. Dielectrics are important in order to explain various phenomena in Solid-State Physics and in Physics of Biological Materials. Indeed, during the last two centuries, many scientists have tried to explain and model the dielectric relaxation. Starting from the Kohlrausch model and passing through the ideal Debye one, they arrived at more com- plex models that try to explain the experimentally observed distributions of relaxation times, including the classical (Cole-Cole, Davidson-Cole and Havriliak-Negami) and the more recent ones (Hilfer, Jonscher, Weron, etc.). The purpose of this thesis is to discuss a variety of models carrying out the analysis both in the frequency and in the time domain. Particular attention is devoted to the three classical models, that are studied using a transcendental function known as Mittag-Leffler function. We highlight that one of the most important properties of this function, its complete monotonicity, is an essential property for the physical acceptability and realizability of the models. Lo studio delle proprietà dielettriche riguarda l’immagazzinamento e la dissipazione di energia elettrica e magnetica nei materiali. I dielettrici sono importanti al fine di spiegare vari fenomeni nell’ambito della Fisica dello Stato Solido e della Fisica dei Materiali Biologici. Infatti, durante i due secoli passati, molti scienziati hanno tentato di spiegare e modellizzare il rilassamento dielettrico. A partire dal modello di Kohlrausch e passando attraverso quello ideale di Debye, sono giunti a modelli più complessi che tentano di spiegare la distribuzione osservata sperimentalmente di tempi di rilassamento, tra i quali modelli abbiamo quelli classici (Cole-Cole, Davidson-Cole e Havriliak-Negami) e quelli più recenti (Hilfer, Jonscher, Weron, etc.). L’obiettivo di questa tesi è discutere vari modelli, conducendo l’analisi sia nel dominio delle frequenze sia in quello dei tempi. Particolare attenzione è rivolta ai tre modelli classici, i quali sono studiati utilizzando una funzione trascendente nota come funzione di Mittag-Leffler. Evidenziamo come una delle più importanti proprietà di questa funzione, la sua completa monotonia, è una proprietà essenziale per l’accettabilità fisica e la realizzabilità dei modelli.

El humor luciánico en las Narrativas Verdaderas : una estética del desencanto

De la lectura de las Narrativas Verdaderas se sale sin conmoción y sin indiferencia, lo que no es una combinación sencilla de sensaciones y de algún modo nos obliga a corrernos de los roles habituales de la recepción para ‘pensar’. En la lectura que proponemos de Narrativas, Luciano se ubica dentro de la tradición filosófica cínica, basada en la acción y exigente de consecuencia entre el decir y el hacer. Desde su materialismo esencial se aparta, pues, del idealismo de su querido Platón y, a partir de ese sentido de la existencia y en consecuencia con él, encontramos una base para entender su sentido del humor. Para Luciano –y esto se hace evidente desde el título hasta la última escena de Narrativas–, la mentira y los mentirosos son cómicos en todas sus formas. Confrontar la mentira con la realidad de la vida es base de la risa luciánica; más allá de Aristóteles y su algo obvia definición de la risa como humana, Luciano especifica el concepto en dirección a lo ‘culturalmente humano’.

El conflicto causalidad natural-libertad en la Crítica de la razón pura

El artículo analiza los argumentos en torno de los cuales se plantea el conflicto entre causalidad natural y causalidad por libertad en la obra Crítica de la Razón Pura /Kritik der reinen Vernunft/ del filósofo alemán Immanuel Kant. Específicamente, interesa desarrollar la solución kantiana a uno de los conflictos que los resultados de la crítica han generado, a partir de la Dialéctica Trascendental y su presentación del problema como antinomia de la razón y de la Doctrina Trascendental del Método, donde la noción de libertad es anunciada como núcleo del pensamiento moral. Se trata de la dificultad que enfrenta la razón al compaginar la necesidad en la naturaleza (sin la cual no es posible la ciencia) con la libertad humana (sin la cual no es posible la moral). La libertad inquirida por el examen crítico de la razón en su uso teórico, es restaurada desde la perspectiva de la razón práctica. Gracias a la restricción crítica del conocimiento humano, Kant abre el camino para la libertad humana, no tanto en los términos negativos de encontrarse “libre de coacción" sino en el sentido positivo de iniciar algo nuevo o no previsto en decurso de la historia fenoménica.

Sobre la eficacia histórica de las ideas : la ética protestante y el espíritu del capitalismo

Max Weber desarrolló gran parte de su obra en diálogo con Marx, como lo han insinuado varios autores y lo hemos estudiado detenidamente en otra parte. El objetivo de este trabajo es determinar cómo se desarrolla ese “diálogo" (explícito o implícito) con la concepción materialista de la historia -que para Weber es sinónimo de “interpretación económica de la historia"-, en una de las obras más célebres del pensador alemán: “La ética protestante y el espíritu del capitalismo". A la vez, mediante un repaso de la literatura secundaria, se intenta observar cómo ha sido interpretada esta obra a lo largo de la historia de la teoría sociológica, desde el punto de vista de la tensión materialismo / idealismo.

Un rasgo medieval de la tolerancia en Buenaventura : la cohibitio

En diversos pasajes de su Comentario a las Sentencias Buenaventura aborda el tema de las faltas veniales incorporando, en un marco teológico, una acepción del concepto de tolerancia heredada de los victorinos, el de ‘cohibitio’, para indicar un aspecto de la permisión que, por oposición al concepto de ‘prohibitio’, señalaría la posibilidad de tolerar una falta venial con el fin de evitar un mal mayor. Este trabajo presenta un seguimiento del concepto de cohibitio en los usos previos a Buenaventura, y señala en este último la vinculación de la tolerancia con el resto de las virtudes mediante la forma común o ‘forma directiva’: la caridad, que otorga a las virtudes un complemento en su ordenación natural al Bien como fin último. En este contexto, se muestra asimismo cómo la estructura conceptual de la teoría de las virtudes en Buenaventura sigue un esquema filosófico que encuentra su fundamentación metafísica en la unidad de los trascendentales.

Elements of the reception of aristotelian thought in 19th century german-language philosophy and economics

La cuestión de la interpretación de Aristóteles por parte de la Academia alemana del siglo XIX es de interés tanto para filósofos como para economistas. Esto se debe a que el pensamiento clásico constituyó una cuestión de discusión e inspiración para el Idealismo, el Hegelianismo, el Historicismo y los economistas históricos alemanes (comenzando por Roscher) y su oponente austríaco, Carl Menger, fundador de la Escuela Austríaca de Economía. De este modo la filosofía antigua permaneció vigente. Al evaluar esta recepción, en este trabajo se muestra que el debate sobre entidades colectivas versus individualidad encuentra allí una base, y el individualismo metodológico, una justificación. Esto resulta útil aún hoy en el siglo veintiuno, en que presenciamos una crisis de la corriente principal de la economía.

Los Discursos a la nación alemana de Fichte : ¿Un “paso atrás" en el proyecto político de la Ilustración?

El presente artículo, de carácter correctivo (νουθεσία), se enfrenta con una serie de juicios condenatorios lanzados sobre la obra de Fichte mencionada en el título, a cuya naturaleza filosófica no se le hace la debida justicia en la medida en que, como suele ocurrir, se la considera desde una perspectiva puramente política.

Robespierre y Sade : Ética, Estética y Política en el ocaso del Siglo de las Luces

La preocupación por definir una pauta de comportamiento éticamente correcto una vez que se cuestiona la trascendencia es central en todo el pensamiento ilustrado francés. El objetivo del presente trabajo es reconstruir algunas de las ideas sobre la moral expuestas en sus discursos por el líder jacobino, Robespierre, y demostrar de qué modo son desarmadas y puestas en ridículo en la literatura del Marqués de Sade mediante una particular concepción de la naturaleza. En ella, como veremos, se condensa una doble crítica: por un lado, al ideal rousseauniano que supone que el hombre es originariamente bueno y depravado por las instituciones y, por el otro, a la posición de Robespierre que sostiene que una República puede erigirse sobre la virtud. La elaboración sadiana del concepto de “naturaleza", expresada fundamentalmente en La philosophie dans le boudoir a través de la voz de Dolmancé, se convierte en la herramienta fundamental para socavar los presupuestos iluministas sobre los que se asienta la moralidad revolucionaria.
