No século XVII, vemos a emergência de uma nova abordagem geométrica às seções cônicas. Desenvolvida inicialmente por Girard Desargues e por Blaise Pascal, tal geometria é herdeira do método de representação pela perspectiva linear a aponta na direção da geometria projetiva do século XIX. Estudos recentes de J. Echeverría e de V. Debuiche iniciaram a discussão da recepção de tais trabalhos por Leibniz, assim como a relação deles com os trabalhos do próprio Leibniz em perspectiva e com a Geometria situs. (...) Este artigo percorre algumas questões associadas a estes domínios, assim como a importância do paradigma da perspectiva para a filosofia de Leibniz. (shrink)

Mitochondrial dysfunction has long been considered a key mechanism in the ageing process but surprisingly little attention has been paid to the impact of mitochondrial number or density within cells. Recent reports suggest a positive association between mitochondrial density, energy homeostasis and longevity. However, mitochondrial number also determines the number of sites generating reactive oxygen species (ROS) and we suggest that the links between mitochondrial density and ageing are more complex, potentially acting in both directions. The idea that increased density, (...) especially when combined with mitochondrial dysfunction, might accelerate ageing is supported by a negative correlation between mitochondrial density and maximum longevity in an interspecies comparison in mammals, and by evidence for an intimate interconnection between cellular ROS levels, mitochondrial density and cellular ageing. Recent data suggest that retrograde response, which activates mitochondrial biogenesis, accompanies cellular ageing processes. We hypothesise that increased mitochondrial biogenesis, and possibly also impaired degradation and segregation of mitochondria, if occurring as adaptation to pre‐existing mitochondrial dysfunction, might aggravate ROS production and thus actively contribute to ageing.

The article examines the concept of “cultural trauma”, which appeared at the beginning of the 21st century as part of the process of searching for identity. The concept is defined as an evaluative metaphor. There are periods in the history of Russia that can be considered from the point of view of using this concept. It is shown how the historical and ideological disputes of the late twentieth century acquired the character of religious contradictions. A hypothesis is put forward as (...) a result of what events the concepts of normal political science vocabulary lost their original meaning and turned into ideological templates. (shrink)

The present paper explores the role of motivation to observe a certain outcome in people’s predictions, causal attributions, and beliefs about a streak of binary outcomes. In two studies we found that positive streaks lead participants to predict the streak’s continuation, but negative streaks lead to predictions of its end. More importantly, these wishful predictions are supported by strategic attributions and beliefs about how and why a streak might unfold. Results suggest that the effect of motivation on predictions is mediated (...) by a serial path via causal attributions to the teams at play and belief in the hot hand. (shrink)

Attitudes toward robots influence the tendency to accept or reject robotic devices. Thus it is important to investigate whether and how attitudes toward robots can change. In this pilot study we investigate attitudinal changes in elderly citizens toward a tele-operated robot in relation to three parameters: (i) the information provided about robot functionality, (ii) the number of encounters, (iii) personality type. Fourteen elderly residents at a rehabilitation center participated. Pre-encounter attitudes toward robots, anthropomorphic thinking, and personality were assessed. Thereafter the (...) participants interacted with a tele-operated robot (Telenoid) during their lunch (c. 30 min.) for up to 3 days. Half of the participants were informed that the robot was tele-operated (IC) whilst the other half were naïve to its functioning (UC). Post-encounter assessments of attitudes toward robots and anthropomorphic thinking were undertaken to assess change. Attitudes toward robots were assessed with a new generic 35-items questionnaire (attitudes toward social robots scale: ASOR-5), offering a differentiated conceptualization of the conditions for social interaction. There was no significant difference between the IC and UC groups in attitude change toward robots though trends were observed. Personality was correlated with some tendencies for attitude changes; Extraversion correlated with positive attitude changes to intimate-personal relatedness with the robot (r = 0.619) and to psychological relatedness (r = 0.581) whilst Neuroticism correlated negatively (r = -0.582) with mental relatedness with the robot. The results tentatively suggest that neither information about functionality nor direct repeated encounters are pivotal in changing attitudes toward robots in elderly citizens. This may reflect a cognitive congruence bias where the robot is experienced in congruence with initial attitudes, or it may support action-based explanations of cognitive dissonance reductions, given that robots, unlike computers, are not yet perceived as action targets. Specific personality traits may be indicators of attitude change relating to specific domains of social interaction. Implications and future directions are discussed. (shrink)

From the editors of Voprosy filosofii: In implementing the historical program for peace adopted by the Twenty-sixth Congress of the CPSU, the Soviet Union is pursuing a principled line in its foreign policy that is aimed at achieving a concrete solution to the problem of disarmament, the consolidation of universal peace, and the security of nations. All these questions have an important sociophilosophical meaning. The world is currently going through a very complicated period. The savage attacks on socialism and national (...) liberation movements being mounted by the reactionary circles of the contemporary bourgeoisie have complicated the international situation. Under these conditions the problems attendant on the struggle for peace, and against the threat of nuclear war, have acquired an extremely timely importance. Our journal regularly publishes materials on this topic. In the present issue the readers have been given a selection of articles on the various sociophilosophical aspects of the struggle for peace and social progress. (shrink)

I Would like to draw attention to the basic defect in the argument used by Mr J. R. Lucas.Mr Lucas there states that Gödel's theorem shows that any consistent formal system strong enough to produce arithmetic fails to prove, within its own structure, theorems that we, as humans, can nevertheless see to be true. From this he argues that ‘minds’ can do more than machines, since machines are essentially formal systems of this same type, and subject to the limitation implied (...) by Godel's theorem. (shrink)

Robert de Sorbon’s De consciencia, edited here, is a pastoral work which concentrates on the examination of conscience as a preliminary to confession. Robert uses the structural motif of the university examination and explores the parallels and contrasts between the relatively severe Chancellor of the university of Paris and the uncompromisingly severe Judge of the Last Judgement. Apart from its pastoral contents the work presents illuminating glimpses of university life in 13th-century Paris. Though known to students in Chambon’s edition of (...) 1902, the De consciencia has hitherto never been printed in full. The reason for this is that Chambon and his 16th and 17th-century predecessors based themselves on a truncated manuscript version which presents only the first part, which constitues no more than half the treatise. An examination of all twenty hitherto identified manuscript versions of the work reveals, however, the existence of as many as four mutually independendent redactions of the work, three of which represent complete versions, whereas the fourth, represented by the Chambon version, is deficient. The present article contains a critical, annotated edition of what is probably the most interesting of the three full redactions, namely the one preserved in Paris, Bibliothèque Nationale, MS Latin 3218. The introduction to the edition contains sections discussing the contents of the work, its redactions and paraphrases, its structure and sources, as well as the relationship to Robert de Sorbon’s other works, including his sermons.

Robert de Sorbon’s Cum repetes — or De modo audiendi confessiones et interrogandi as it is called in the Bruges manuscript — is for the clergy what Robert’s Qui vult vere confiteriis for laymen. It is a guide for confessors, specifically addressed to those charged with the cura animarum to provide practical instruction on how to interrogate the penitent and assist him in examining his conscience. It is this subject that determines and delimits its scope. In terms of the tripartite (...) nature of the sacrament of penance, i.e. contrition, confession and satisfaction, Cum repetes concentrates almost exclusively on the central part, confession, and on the proper method of interrogation by the confessor. A characteristic feature of Robert’s treatise is the introduction of a number of model dialogues between the confessor and the penitent, comparable to the interchanges in Robert of Flamborough’s Liber Poenitentialis, but much more incisive and inspired by great sollicitude as well as personal involvement.

This study presents examples, not previously available in print, of the frequent use of the imagery of commerce in Robert de Sorbon’s sermons and discusses the imagery’s relation to scriptural and patristic sources, in particular the apostle Paul and Augustine of Hippo. It is argued that Robert’s use of the language of the marketplace in discussions of theological and moral matters functions as a rhetorical tool which emphasizes the boundlessness of God’s mercy through the redemption.

In an interesting work ‘The Ethical Animal’ Professor C. H. Waddington valiantly attempts to bridge the gap between ‘ought’ and ‘is’ without, it seems, succeeding in doing so. Notwithstanding his erudition, honesty of purpose and charm in exposition, the gulf remains unbridged. Indeed there are passages where it is difficult to be certain whether the author considers that he has bridged it or even what standpoint he finally adopts.
