Axiomatization of ‘Peircean’ branching-time logic

The branching-time logic called Peircean by Arthur Prior is considered and given an infinite axiomatization. The axiomatization uses only the standard deduction rules for tense logic.     

A very obscure definition: Descartes’s account of love in the Passions of the Soul and its scholastic background

The definition of love given by Descartes in the Passions of the Soul (art. 79–84) has never stopped puzzling commentators. If the first Cartesian textbooks discreetly evoke or even fail to discuss Descartes’s account of love, Spinoza harshly criticizes it, pointing out that it is ‘on all hands admitted to be very obscure’. More recently several scholars have noticed the puzzling (or even paradoxical) character of the articles of the Passions of the Soul on love and hate. In this paper, I would like to propose a reassessment of the definition of love provided by the Passions of the Soul and the Letters to Elisabeth and Chanut. By tracing back Descartes’s scholastic sources (namely Aquinas’s treatises on the passions and charity in the Summa Theologiae), I will demonstrate how Descartes builds up his definition of love by displacing or subverting the meaning of several major elements of the thomistic vulgata on love. Hence, a significant part of the obscurity of the definition given by the Passions of the Soul possibly finds its ultimate rationale in this attempt to recover some traditional questions of the scholastic debate on love, while advancing new answers to them.     

The New Alliance Between Science and Education: Otto Neurath’s Modernity Beyond Descartes’ ‘Adamitic’ Science

Starting from a suggestion of Stephen Toulmin and through an interpretation of the criticism to which Neurath, one of the founders of the Vienna Circle, submits Descartes’ views on science, the paper attempts to outline a pattern of modernity opposed to the Cartesian one, that has been obtaining over the last four centuries. In particular, it is argued that a new alliance has to be established between science and education, overcoming Descartes’ banishment against education. In a Neurathian perspective education is a key-moment of the scientific enterprise without which science itself is in danger of going astray and no scientific outlook is promoted in the society at large. Such an anti-Cartesian attitude is a leitmotiv of the whole Neurath’s production and characterizes his fundamental approach to the sense of modernity. For this reasons, despite all its shortcomings, Neurath’s proposal represents a very promising option for a new agenda of the modernity away from Descartes’ spell. By elaborating on Neurath’s (and Dewey’s) insights, the paper puts forward the idea that philosophy of science (such as it was originated by neopositivism in its Reichenbachian version) should give way to an educational philosophy of science which could allow us “to bring the genuine modern into existence”.     

Brain processing of task-relevant and task-irrelevant emotional words: An ERP study

Although there is evidence for preferential perceptual processing of written emotional information, the effects of attentional manipulations and the time course of affective processing require further clarification. In this study, we attempted to investigate how the emotional content of words modulates cerebral functioning (event-related potentials, ERPs) and behavior (reaction times, RTs) when the content is task-irrelevant (emotional Stroop Task, EST) or task-relevant (emotional categorization task, ECT), in a sample of healthy middle-aged women. In the EST, the RTs were longer for emotional words than for neutral words, and in the ECT, they were longer for neutral and negative words than for positive words. A principal components analysis of the ERPs identified various temporospatial factors that were differentially modified by emotional content. P2 was the first emotion-sensitive component, with enhanced factor scores for negative nouns across tasks. The N2 and late positive complex had enhanced factor scores for emotional relative to neutral information only in the ECT. The results reinforce the idea that written emotional information has a preferential processing route, both when it is task-irrelevant (producing behavioral interference) and when it is task-relevant (facilitating the categorization). After early automatic processing of the emotional content, late ERPs become more emotionally modulated as the level of attention to the valence increases.

Indicadores aislados versus patrón general expresivo en la detección de la mentira

Resumen

Frente a planteamientos teóricos clásicos, en relación con el fenómeno de la detección de la mentira, que postulan que la existencia de indicadores no verbales aislados facilitan el reconocimiento de mensajes falsos, este trabajo plantea la existencia de un patrón general de configuración que varía cualitativamente para mensajes verdaderos y falsos. Las condiciones experimentales ideadas para este trabajo (presentación de mensajes falsos, precedidos o no de mensajes verdaderos) permitieron a los sujetos experimentales contrastar las diferencias entre estos patrones, facilitando el reconocimiento de mensajes fraudulentos, siendo las mujeres las que mejor aprovecharon las condiciones facilitadoras.
