Antero de Quental: a última palavra da natureza é 'ética'

Antero de Quental (1842-1891) is best known for his poetic work. Nevertheless, alongside this literary work, and in close correlation with it, he produced a corpus of philosophical texts of great depth and relevance. Nature composes a unifying thematic core for his work, and is implicit throughout the author’s entire work. In this paper, we seek to establish the main tendencies of his Evolutionism, both from the positive and metaphysical points of view. On his last work (Tendências gerais da filosofia na segunda metade do século XIX), the author talks about "good" as the fundamental principle of all human actions and of nature itself: the last word of nature is written by the human consciousness whenever a good action is performed. This opens the door to a spiritual Evolutionism and explains the moral world view that we can find in Antero de Quental's thought.

A Novel Short-Step Synthesis of New Xanthenedione Derivatives from the Cyclization of 3-Cinnamoyl-2-styrylchromones

Novel (E)-3-aryl-4-benzylidene-8-hydroxy-3,4-dihydro-1 H-xanthene-1,9(2H)-diones are prepared by the cyclization of (E,E)-3-cinnamoyl-5-hydroxy-2-styrylchromones efficiently catalyzed with boron tribromide. The (E,E)-3-cinnamoyl-5-hydroxy-2-styrylchromones are obtained from the Baker–Venkataraman rearrangement of (E,E)-2-acetyl-1,3-phenylene bis(3-phenylacrylate), which is greatly improved under microwave irradiation.

Building the «true evolutionism»: Darwin's impact on Henri Bergson's thought

The paper focuses on the importance of Darwin’s work for the shaping of Henri Bergson’s philosophy, bearing on mind that the two authors first intercepted symbolically in 1859, when On the Origin of Species was published and Bergson was born. Bergson studied the biological sciences of his time, whose results were integrated in a metaphysical thought. He belonged to spiritualistic positivism, a philosophy that goes from the positive data of sciences and finds the ultimate explanation of reality in a spiritual principle. He was interested in the positive evolution of the natural world and in the works of naturalists such as Lamarck, De Vries or Eimer. Darwin was among these authors, being responsible for a vision of evolution that went from the scientific level to other domains. Bergson defends the “insufficiency of pure Darwinism” by pointing out the necessity to compensate scientific evolution with an internal metaphysical reading of the real, which he considered to be “true evolutionism”. This criticism is the most visible aspect of the relations between both works. However, an attentive look verifies that Darwin’s influence overcomes the divergence of positions concerning the extent of “evolution”. The French philosopher knew not only the 1859’s bestseller, but also studies by Darwin about ethology, entomology and botany, which contributed to the fact that the naturalist’s impact gained fundamental importance in Bergson’s philosophical perspective.

La traduction de renvois intertextuels dans le roman contemporain : Histoire du Siège de Lisbonne de Saramago et Vou-me embora d'Echenoz

Une des caractéristiques du roman contemporain qui constitue un défi pour le traducteur est l'usage constant que les auteurs y font de l'intertextualité. Ce recours à des renvois intertextuels crée, dans le roman, un rapport ludique selon lequel l'auteur introduit dans son texte des passages au statut différent, que le lecteur devrait trouver et interpréter. Traduire ces romans et ces procédés intertextuels exige du traducteur qu'il assume un rôle différent de celui que la tradition lui accorde: non plus celui du traducteur-reproducteur, mais celui du traducteur-créateur.

The Bergsonian intuition of duration : the time of science is space

According to Bergson, the philosophical tradition had been unanimous in declaring the question of time essential. However, it had neglected its correct framing which, for the author, lies in the metaphysical approach of an immediate and inner experience of concrete duration. In the current paper, we shall present Henri Bergson's concept of time, particularly the author's critique to the scope scientific discourse has of this concept. Simultaneously, we shall explore the central role of time in the Bergsonian thought, metaphorically understood as the very stuff of reality. We shall not, therefore, explore Bergson's ideas on Physics, but some of the metaphysical consequences that he withdraws from certain physics' concepts or theories.

Mapping stability : real rational maps of degree zero

In memory of our beloved Professor José Rodrigues Santos de Sousa Ramos (1948-2007), who João Cabral, one of the authors of this paper, had the honor of being his student between 2000 and 2006, we wrote this paper following the research by experimentation, using the new technologies to capture a new insight about a problem, as him so much love to do it. His passion was to create new relations between different fields of mathematics. He was a builder of bridges of knowledge, encouraging the birth of new ways to understand this science. One of the areas that Sousa Ramos researched was the iteration of maps and the description of its behavior, using the symbolic dynamics. So, in this issue of this journal, honoring his memory, we use experimental results to find some stable regions of a specific family of real rational maps, the ones that he worked with João Cabral. In this paper we describe a parameter space (a,b) to the real rational maps fa,b(x) = (x2 −a)/(x2 −b), using some tools of dynamical systems, as the study of the critical point orbit and Lyapunov exponents. We give some results regarding the stability of these family of maps when we iterate it, specially the ones connected to the order 3 of iteration. We hope that our results would help to understand better the behavior of these maps, preparing the ground to a more efficient use of the Kneading Theory on these family of maps, using symbolic dynamics.
