La conciencia fenoménica es la propiedad que los estados, sucesos y procesos mentales poseen cuando, y sólo cuando, hay algo que es como algo para el sujeto que los posee; para experimentarlos o estar en tales estados. Hay algo que es como oler café recién preparado. Tener la experiencia de oler café recién preparado es un estado fenoménicamente conciente. Comúnmente, qué es algo como tener una experiencia conciente refiere al carácter fenoménico de las experiencias. Las teorías de la conciencia intentan (...) explicar éste carácter fenoménico.

En el presente artículo se muestra que en la cosmología cartesiana no resulta claro cómo se puede hablar o referir a cuerpos individuales en el marco de un universo absolutamente compacto. Se defiende que el concepto de cuerpo individual en el interior de dicha cosmología se puede construir como una ficción del espíritu. Un cuerpo individual se puede construir como la extensión que se encuentra encerrada en una superficie maximal cuyas subdivisiones carecen de movimiento relativo entre sí. Se muestra, también, (...) que la cosmología cartesiana puede presentarse como un modelo trivial de la Teoría M. (shrink)

The aim of this study was to carry out a psychosocial analysis of child-to-parent violence (CPV) in a sample of school adolescents, considering a set of individual variables (psychological distress, problematic use of social networking sites, and perceived non-conformist social reputation) and family variables (open and problematic communication with parents) according to sex. The sample consisted of 3,731 adolescents (54% boys), aged between 14 and 16 years (M = 14.6 years, SD = 0.567), from the state of Nuevo León, Mexico. (...) The scores of the boys and girls were analyzed to check for differences. Also, correlations between all the study variables were calculated. Finally, a multiple stepwise regression analysis was carried out for the total sample and also for boys and girls separately. Results confirmed the important role of individual variables as predictors of CPV in boys and girls. The main difference between boys and girls was observed in the predictive weight of problematic use of social networking sites, which was higher in girls than in boys. Open communication with the father was a significant factor for predicting the decrease of CPV levels in the case of boys, while open communication with the mother predicted the decrease of CPV in girls. Problematic communication with the mother showed similar values in boys and girls when predicting CPV, however, the predictive weight of problematic communication with the father was higher in girls than in boys. These results are interesting and have important implications for the prevention of CPV. (shrink)

Johannes Kepler dedicated much of his work to discover a law for the refraction of light. Unfortunately, he formulated an incorrect law. Nevertheless, it was useful for anticipating the behavior of light in some specific conditions. Some believe that Kepler did not have the elements to formulate the law that was later accepted by the scientific community, that is, the Snell–Descartes law. However, in this paper, we propose a model that agrees with Kepler’s heuristics and that is also successful in (...) anticipating the behavior of light when it passes through a surface that separates two media with different optical densities. This model adopts strategies that were recommended by Kepler in two types of analogies. The obstacles that led to the failure of the two types of analogies are presented in the article, and we argue that the model proposed here could overcome these specific obstacles. Finally, we show how the proposed model could be articulated with Kepler’s metaphysics of light. (shrink)

In the frame of the celebration of the century of the publication that gave way to the special theory of relativity, a semblance of the discussions generated from the philosophical implications that derive from the possibility of accepting non-euclidian frames for our space of representation. Poncaré’s argument is exposed in defense of geometrys principle of relativity and the criticism formulated by Hans Reichenbach is discussed.

Every area of knowledge is based on a variety of products of conceptual engineering. This article is programmatic in essence: it aims at introducing a model of how conceptual engineering works and, particularly, how conceptual innovation is achieved in the context of theoretical inquiry. First, it describes the context in which the explicit study of the relevance, scope, mechanisms, and aims of conceptual engineering was born. Secondly, it introduces a distinction between evaluative and instrumental conceptual engineering based on the difference (...) between committed and instrumental conceptual use. According to this, it argues that both evaluative and instrumental conceptual engineering might be formally seen as the result of one function, which, provided a conceptual problem, maps to possible conceptual solutions generating success or failure values. Lastly, it introduces a third kind of conceptual engineering, namely, constructive conceptual engineering. Its core is a function that maps solutions to a representational space of non-considered alternatives, thus generating new conceptual content. In general, the proposed model offers a productive and novel field of inquiry on the conditions and factors that grounds theoretical innovation through conceptual engineering. (shrink)

Wittgenstein defiende que los problemas filosóficos son ilegítimos. Sin embargo, no resulta del todo claro qué se entiende en general por problema filosófico, cuál es, pues, su naturaleza. El presente artículo intenta elucidar la observación de Wittgenstein que sostiene que la forma de un problema filosófico se puede presentar con la expresión “Yo no sé salir del atolladero” (IF § 123). En el artículo se elige, a manera de ejemplo, el escándalo kantiano, que demanda que demostremos con el uso de (...) la razón que la proposición “hay objetos físicos” es verdadera. Sin renunciar al ejemplo, se explora en qué sentido la expresión de Wittgenstein caracteriza en buena medida la naturaleza misma de la dificultad filosófica. En el ejercicio se atienden recomendaciones formales del Tractatus, terapias desplegadas en Sobre la Certeza y el recurso de distinguir entre sentido primario y sentido secundario de una expresión insinuado en las Investigaciones Filosóficas.

En el artículo se examina la controversia entre extramisionismo e intramisionismo a propósito de la percepción visual. Se defiende que la evaluación del cierre de la controversia depende del explanandum que rastrea el filósofo/historiador en la reconstrucción que persigue. Si enfatizamos en los mecanismos causales, la controversia se cerró en favor del intramisionismo. Si enfatizamos en aspectos asociados con la intencionalidad o con la forma como ciertas afecciones mentales refieren a objetos externos, la controversia conduce a una conciliación entre intramisionismo (...) causal y extramisionismo mental. Finalmente, si ponemos en duda la necesidad de una distinción entre interno/externo, la controversia se disuelve por carecer de sentido. (shrink)

Euclid proposed to trace pyramids as artifacts to facilitate the study of visual perception. The artifact assumes that the object seen delimits the base of a pyramid at the apex of which is the perceived eye. The artifact faces a serious difficulty when we notice that visual perception is carried out with two cooperating eyes. The article discusses two attempts to modify the Euclidean artifact to make it work without giving up the central assumptions. These attempts correspond to the classical (...) studies of Ptolemy’s binocular vision and Ewald Hering’s contributions in the 19th century. (shrink)

El artículo examina tres propuestas de explicación del fenómeno de refracción de la luz formuladas por los pensadores medievales Roger Bacon, John Pecham y Erazmus Ciolek Witelo. Se muestra, en el caso de Bacon, que la explicación estaba soportada en una metafísica de la propagación de los poderes causales y anidaba un conflicto insalvable. En el caso de Pecham se muestra un mayor compromiso con la necesidad de una ley cuantitativa que, desafortunadamente, conduce a una explicación frustrada. Finalmente, se valora (...) el deseo de Witelo por introducir elementos cosmológicos en su explicación. (shrink)

Since Seligman's 1971 statement that the vast majority of phobias are about objects essential to the survival of a species, a multitude of laboratory studies followed, supporting the finding that humans learn to fear and detect snakes (and other animals) faster than other stimuli. Most of these studies used schematic drawings, images, or pictures of snakes, and only a small amount of fieldwork in naturalistic environments was done. We address fear preparedness theories, and automatic fast detection data from mainstream laboratory (...) data and compares it with ethobehavioural information relative to snakes, predator-prey interaction, and snakes’ defensive kinematics strikes in order to analyse their potential matching. From this analysis four main findings arose, namely that: 1) Snakebites occur when people are very close to the snake and are unaware or unable to escape the bite; 2) Human visual detection and escape response is slow compared to the speed of snake strikes; 3) In natural environments, snake experts are often unable to see snakes existing nearby; 4) animate objects in general capture more attention over other stimuli and dangerous but recent objects in evolutionary terms are also able to be detected fast. The issues mentioned above pose several challenges to evolutionary psychology-based theories expecting to find special-purpose neural modules. The older selective habituation hypothesis (Schleidt, 1961), that prey animals start with a rather general predator image from which specific harmless cues are removed by habituation might deserve reconsideration.

This article analyzes the bioethical implications of using a control/placebo group when conducting clinical trials (CTs) investigating the treatment of periodontitis. For this, the deductive method was used, proposing the interrelation of values, and a scoping systematic review was carried out. A total of 53% of the CTs reviewed were performed in low- and middle-income (LMI) countries, and 92% used a control/placebo group as a comparison group. Although there is a gold standard for the adjunctive treatment of periodontitis, the research (...) ethics committees of most of the analyzed studies approved the use of control/placebo groups for the performance of CTs that did not explore new therapeutic alternatives. In some cases, the CT protocols were not approved by ethics committees, nor was informed consent used. In the LMI countries, a shorter period of recruitment was observed for patients who attended universities and public hospitals. Likewise, most of the CTs reviewed had public funding, a significant amount of which came from the pharmaceutical industry. Only one CT reported the low economic and educational level of its participants. Furthermore, none of the authors of the reviewed CTs declared conflicts of interest. Although the axiology of techno-science always takes into account at least the epistemic, technical and economic value systems, the hegemony of the economic values imposed by the pharmaceutical industry is evident in the performance of CTs investigating the treatment of periodontitis in LMI countries.

The existence of sovereign rights over genetic resources is today well recognized in international law. However, the legal status of such resources in terms of property rights is still unclear. The consideration of this issue requires a clear distinction between physical and intangible property. Legislation in developed countries has extended patent protection to genetic resources, in addition to the protection of plant varieties via breeders' rights. The extension of protection and the implementation of the TRIPs Agreement may have important implications (...) for breeding programs and trade in seeds. While intellectual property protection of genetic resources is rapidly advancing, considerable work is still to be done to ensure the compensation for the informal innovations made by local and indigenous communities.

The aim of this note is to undermine structural realism by testing the soundness of its main claim. If scientific theories represent the structure of the world, structural realism needs a general account of representation. Representation is the crux of structural realism, because structure/ontology distinction collapses. Mathematical structures are ontologyladen. DOI:10.5007/1808-1711.2010v14n2p201.

This book argues for a new reading of the political and ethical through the literatures of Argentina, Chile, and Paraguay from 1970-2000. Carlos Amador reads a series of examples from the last dictatorship and the current post-dictatorship period in the Southern Cone, including works by Augusto Roa Bastos, Roberto Bolaño, Ceferino Reato, Horacio Verbitsky, Nelly Richard, Diamela Eltit, and Willy Thayer, with the goal of uncovering the logic behind their conceptions of belonging and rejection. Focusing on theoretical concepts that (...) make possible the formation of any and all communities, this study works towards a vision of literature as essential to the structure of ethics. (shrink)

The following section defends that if scientific theories represent the structure of the world, structural realism needs a general account of representation. Representation is the crux of structural realism. Section 3 argues that structure/ontology distinction collapses. Mathematical structures are ontologyladen. Lastly, section 4 is devoted to analyse whether there is (...) a retention of mathematical structure across theory change. (shrink)

In the so-called knowledge society, communication plays a key role in organizations. In traditional societies, the exchange of personal communication was conducted _face to face_. The development of new technologies has expanded the possibilities of transmitting more information within organizations and faster. Technology has brought greater opportunities for collective communication, as well as greater information management. The impact of these factors has led to some very significant changes in the business world. In these processes of change, within organizations, the role (...) of communication is increasingly playing a critical role. This article defends the relevance of ethical communication in 21st Century leadership. It is argued that leaders will find in ethical communication the means of gaining credibility and the confidence of their most immediate collaborators, their teams, the organizations they lead and the society in which the company operates. Taking the fundamental structure between internal and external communication as a starting point, the article describes the necessary conditions for leadership to develop ethical communication. It establishes the general and common characteristics of people-centered ethical communication, both as individuals and teams. Furthermore, it identifies the conditions that must generate ethical external communication through which leaders can convey messages to their target audience. For this purpose, the article is structured into the following sections: 1. The importance of communication within organizations. 2. Two levels of communication. 3. What is required of a leader-communicator in order to communicate well? 4. The basic Q&A of communication. (shrink)

The manuscript tradition of Proba’s "Cento" was investigated by K. SCHENKL, whose edition (CSEL 1888) remains the basis of every further inquiry. He knew some 25 manuscripts, only eleven of which are reported in his apparatus. Going through catalogues I have discovered about 40 new manuscripts, most of which belong to the humanistic age. After listing all the manuscripts, I try to establish their relationships. Although I consider restricted evidence (I have collated systematically about 100 verses), some facts seem to (...) be plain. The humanistic tradition originates from three old manuscripts (Cantabrig. Sanctae Trinitatis O.7.7; Parisinus Lat. 13048; Vaticanus Pal. Lat. 1753), while another very important old manuscript (Parisinus Lat. 7701) has no progeny. I try to place all the manuscripts in a stemma. (shrink)

Understanding evolution beyond a gene-centered vision is a fertile ground for new questions and approaches. However, in this systemic perspective, we take issue with the necessity of the concept of information. Through the example of brain and language evolution, we propose the autonomous systems theory as a more biologically relevant framework for the evolutionary perspective offered by Jablonka & Lamb (J&L).

The aim of this paper is to demonstrate that the tragic poets of the fifth century BC used an engine called ekkyklema in order to reveal the scenes supposed to take place inside. I think I can indicate a passage, that clearly demonstrates the use of such an engine (Eur. Her. 1028 ff.), since the chorus’ words are otherwise unintellegibile. Comic poets used this engine only for paratragic purpose, because the distinction inside/outside was not relevant for comedy.
