Las Confesiones de San Agustín son una obra muy peculiar. Lectores e investigadores convienen en ello. No es fácil ‘definir’ ni comprender ese escrito. El presente estudio intenta una aproximación a su contenido mediante un examen de ciertos rasgos característicos de la obra que derivan de su propia singularidad. Y denunciamos también algunos impedimentos de comprensión y lectura. Confiemos en que esta mirada pueda ofrecer una guía inicial, pero orientadora, a la misma. Además, el estudio formal y temático revela una (...) dinámica interna, de su estructura misma, que va del relato autobiográfico a la reflexión (consideratio), de lo narrativo al pensamiento. Este avance tendencial culmina al concluir el libro IX, donde la dimensión narrativa de la obra termina. Razón por la cual los libros X-XI alcanzan el vértice teorético de las Confesiones, con su investigación de la memoria y del tiempo. El presente estudio concluye con una breve exposición del problema agustiniano de la subjetividad o el yo, en la base de esos dos libros. (shrink)

Based on research on the increasingly popular unconscious thought effect (UTE), it has been suggested that physicians might make better diagnostic decisions after a period of distraction than after an equivalent amount of time of conscious deliberation. However, published attempts to demonstrate the UTE in medical decision making have yielded inconsistent results. In the present study, we report the results of a meta-analysis of all the available evidence on the UTE in medical decisions made by expert and novice clinicians. The (...) meta-analysis failed to find a significant contribution of unconscious thought to the accuracy of medical decisions. This result cannot be easily attributed to any of the potential moderators of the UTE that have been discussed in the literature. Furthermore, a Bayes Factor analysis shows that most experimental conditions provide positive support for the null hypothesis, suggesting that these null results do not reflect a simple lack of statistical power. We suggest ways in which new studies could usefully provide further evidence on the UTE. Unless future research shows otherwise, the recommendation of using unconscious thought to improve medical decisions lacks empirical support. (shrink)

This book provides a detailed reconstruction of the process of formation of the modern concept of society as an objective entity from the 1820s onwards, thus helping to better understand the shaping of the modern world and the nature of the current crisis of modernity. The concept has exerted considerable influence over the last two centuries, during which time many people have conceived themselves and behave as members of a society, and social scientists have explained human subjectivities and conducts as (...) social effects. For both groups, society exists as a very real phenomenon. Historical inquiry shows, however, that the modern concept of society is no more than a historically contingent way of imagining and making sense of the human world.. (shrink)

Higher plants must undergo a major developmental switch, the transition to flowering, if they are to successfully complete their life cycle. In many plants, the crucial decision of when to begin to produce flowers is primarily controlled by environmental signals. The process of floral induction involves the integration of the activities of two types of genes: those that control flowering time as a response to the environment as well as an endogenous clock, and those that determine the floral identity of (...) the cells. The first direct link between these two classes of genes has now been demonstrated(1). Forced expression of CONSTANS, a flowering‐time gene, promotes flowering through the transcriptional activation of LEAFY, a flower‐meristem‐identity gene. (shrink)

This book aims to enrich our understanding of the role the environment plays in processes of life and cognition, from the perspective of enactive cognitive science. Miguel A. Sepúlveda-Pedro offers an unprecedented interpretation of the central claims of the enactive approach to cognition, supported by contemporary works of ecological psychology and phenomenology. The enactive approach conceives cognition as sense-making, a phenomenon emerging from the organizational nature of the living body that evolves in human beings through sensorimotor, intercorporeal, and linguistic (...) interactions with the environment. From this standpoint, Sepúlveda-Pedro suggests incorporating three new theses into the theoretical body of the enactive approach: sense-making and cognition fundamentally consist of processes of norm development; the environment, cognitive agents actually interact with, is an active ecological field enacted in their historical past; and sense-making occurs in a domain consisting of multiple normative dimensions that the author names enactive place.

Authoritative and comprehensive interpretation of the Scottish philosopher's writings on religion.

Copernicus’s De revolutionibus and Girolamo Fracastoro’s Homocentrica were both addressed to Pope Paul III. Their dedicatory letters represent a rhetorical exercise in advocating an astronomical reform and an attempt to obtain the papal favour. Following on from studies carried out by Westman and Barker & Goldstein, this paper deals with cultural, intellectual and scientific motives of both texts, and aims at underlining possible relations between them, such as that Copernicus knew of Fracastoro’s Homocentrica, and that at least part of the (...) rhetorical strategy laid out in De revolutionibus’s dedicatory letter can be read as a sophisticated response to Fracastoro’s arguments.Keywords: Copernicus; Fracastoro; Paul III; History of astronomy; Patronage.

This article outlines the theoretical developments experienced in historical studies over the last two decades. As a consequence of the growing critical reconsideration of some of the main theoretical assumptions underlying historical explanation of individuals' meaningful actions, a new theory of society has taken shape among historians during this time. By emphasizing the empirical and analytical distinction between language as a pattern of meanings and language as a means of communication, a significant group of historians has thoroughly recast the conventional (...) notions of society, experience, interests, culture, and identity, and has developed a new concept of social action. Thus, historiographical debate seems to have started to transcend, for the first time, the longstanding and increasingly futile contest or dilemma between objectivism and subjectivism, between materialism and culturalism, between social and intentional explanation, or between social constraints and human agency. The groundwork has now been laid for an alternative to the declining paradigm of social history that does not entail a revisionist return to idealist history but opens a quite different path.

This paper studies the different conceptions of both centrality and the principle or starting point of motion in the Universe held by Aristotle and later on by Copernicanism until Kepler and Bruno. According to Aristotle, the true centre of the Universe is the sphere of the fixed stars. This is also the starting point of motion. From this point of view, the diurnal motion is the fundamental one. Our analysis gives pride of place to De caelo II, 10, a chapter (...) of Aristotle’s text which curiously allows an ‘Alpetragian’ reading of the transmission of motion.In Copernicus and the Copernicans, natural centrality is identified with the geometrical centre and, therefore, the Sun is acknowledged as the body through which the Deity acts on the world and it also plays the role of the principle and starting point of cosmic motion. This motion, however, is no longer diurnal motion, but the annual periodical motion of the planets. Within this context, we pose the question of to what extent it is possible to think that, before Kepler, there is a tacit attribution of a dynamic or motive role to the Sun by Copernicus, Rheticus, and Digges.For Bruno, since the Universe is infinite and homogeneous and the relationship of the Deity with it is one of indifferent presence everywhere, the Universe has no absolute centre, for any point is a centre. By the same token, there is no place that enjoys the prerogative of being—as being the seat of God—the motionless principle and starting point of motion.Author Keywords: Author Keywords: Aristotle; Copernicus; Bruno; Centrality; Principle of movement; Extension of the Universe.

Helisaeus Roeslin’s manuscript Speculum et harmonia mundi, Das ist Wellt Spiegel Erster Theil was conceived as part of a broader project comprising a Speculum ecclesiae as well as a Speculum naturae. This project was connected with a Chronology aiming to establish the precise date of the most important events in history as well as to advance some conjectures about the approaching eschatological future. This article presents some recent discoveries that shed new light on Roeslin’s chronological work after 1579, most importantly (...) the incontrovertible attribution to Roeslin of the anonymous manuscript De potestatibus orbis Christiani, et politicis et ecclesiasticis, Discursus. Here Roeslin presented his discovery of the numerical proportions governing the numbers of spiritual and temporal potestates in the three historical periods, affirming that these numbers were now nearly fullfilled, along with their ensuing eschatological implications. We show how Roeslin published this discovery in his Kurtz Bedencken against the calendar reform and again in 1612 in a short tract on the occasion of the coronation of Emperor Matthias I. The article focuses in particular on the appended broadsheet Tabella des Welt Spiegels, which displayed the completion and culmination of history, according to the astronomical revolutions of the planets as well as the numbers of temporal and spiritual governors.

This article examines the expansion of agrofuels in the Americas and the ecological impacts associated with the technologies used in the production of large-scale monocultures of corn and soybeans. In addition to deforestation and displacement of lands devoted to food crops due to expansion of agrofuels, the massive use of transgenic crops and agrochemical inputs, mainly fertilizers and herbicides used in the production of agrofuels, pose grave environmental problems.
