Ce texte a paru pour le première fois dans L'année psychologique, vol. 52, n° 1, 1952, p. 39-46. La nature de la perception de la durée est un des problèmes sur lequel les psychologues et les philosophes ont multiplié les interprétations. S'il ne nous est donné, comme le pensaient les premiers psychologues allemands du XIXe siècle, que des sensations successives, le problème de la perception de la durée d'un intervalle vide de sensations extéroceptives ne pouvait se résoudre qu'en essayant de (...) meubler (...) - Psychologie.

A história da psicologia, tal como aparece em algumas obras (E.G. Boring 1950; M. Reuchlin 1957; P. Fraisse e J. Piaget 1963) ou em capítulos introdutórios de alguns manuais (M. Reuchlin 1977), reflete uma adesão — raramente discutida — a uma concepção internalista. Segundo essa concepção, a psicologia seria animada por uma dinâmica própria, um processo evolutivo totalmente endógeno, e seria independente de fatores externos tais como os domínios religiosos, sociopolíticos e econômicos. Além do mais, os partidários dessa história (...) aceitam ver a psicologia influenciada por disciplinas situadas em suas fronteiras, como a biologia, a fisiologia e, em menor medida, a física. Esses domínios fronteiriços geralmente dizem respeito a objetos psicológicos habitualmente qualificados de inferiores, como reflexos, sensações e percepções, em oposição à linguagem e ao pensamento, qualificados como processos superiores. Esses mesmos domínios fronteiriços engendraram por sua vez subdomínios relativamente autônomos, tais como a psicofísica ou a psicofisiologia. Correlativamente a essa concepção internalista, o desenvolvimento científico é apresentado como um caminho ao estado de psicologia positiva, tal como A. Comte a definiu em 1837 na 45a lição do Curso de Filosofia Positiva. A caminhada até a positividade foi indicada pelo próprio A. Comte: estudo da anátomo-fisiologia do sistema nervoso (a frenologia de Gall lhe parece a esse respeito uma contribuição decisiva), estudos comparados, análise de casos patológicos, estudo dos comportamentos animais e do desenvolvimento individual. Considerando a evolução da psicologia nos últimos cem anos, seríamos tentados a sustentar que ela realizou o projeto positivista. Psicologia diferencial, psicopatologia, etologia animal e psicologia da criança são vários domínios que concorrem para essa realização. Entretanto, esses domínios estão longe de parecerem homogêneos quanto aos métodos empregados e os modelos epistemológicos aos quais se referem. Um exame atento dessas dimensões metodológicas e epistemológicas mostra que se avança, sobretudo, em ordem dispersa. (shrink)

The general theory developed by Ben Yaacov for metric structures provides Fraïssé limits which are approximately ultrahomogeneous. We show here that this result can be strengthened in the case of relational metric structures. We give an extra condition that guarantees exact ultrahomogenous limits. The condition is quite general. We apply it to stochastic processes, the class of diversities, and its subclass of $L_1$ diversities.

The notion of a μέσον, formally defined as the «middle term« in a syllogism, plays a pivotal role in Aristotle's theory of scientific demonstrations in his Analytica Posteriora. It is via the μέσον that the distinctive traits of a demonstration – the employment of causal notions and of statements concerning the essence of things – enter into demonstrative syllogisms. This, however, raises problems with respect to the provability of statements concerning the essence of things that Aristotle seems to accept in (...) certain passages of the Analytica Posteriora, as opposed to well-known passages in the Metaphysics. It is shown in which sense essences are in fact demonstrated by their being employed – via the μέσον – in a demonstration, without, however, being mentioned in the conclusion of such a demonstration. The importance Aristotle ascribes to the μέσον in Analytica Posteriora suggests a more flexible, less formalistic understanding of Aristotle's view of science, while still being based on an analysis of the formal structure of the syllogism.

Schelling und Hegel benutzen in ihren philosophischen Texten mathematische und naturwissenschaftliche Modelle wie Unendlichkeit oder Gleichgewicht. Die Strukturen dieser Begriffe liefern einen Massstab fur den Vergleich der Positionen Schellings und Hegels, der fur Schellings Identitatsphilosophie und Hegels erste Jenaer Schriften durchgefuhrt wird. Als wichtigstes Resultat kann eine grundlegende Differenz zwischen beiden Positionen bereits um 1801 nachgewiesen und gezeigt werden, dass diese auf einer unterschiedlichen Auffassung der Rolle des Absoluten beruht.

A philosophical account of risk, such as this book provides, states what risk is, which attitudes to it are rational, and which acts affecting risks are rational. Attention to the nature of risk reveals two types of risk, first, a chance of a bad event, and, second, an act’s risk in the sense of the volatility of its possible outcomes. The distinction is normatively significant because different general principles of rationality govern attitudes to these two types of risk. Rationality strictly (...) regulates attitudes to the chance of a bad event and is more permissive about attitudes to an act’s risk. Principles of rationality governing attitudes to risk also justify evaluating an act according to its expected utility given that the act’s risk, if any, belongs to every possible outcome of the act. For a rational ideal agent, the expected utilities of the acts available in a decision problem explain the agent’s preferences among the acts. Maximizing expected utility is just following preferences among the acts. This view takes an act’s expected utility, not just as a feature of a representation of preferences among acts, but also as a factor in the explanation of preferences among acts. The view extends to evaluations of combination of acts, either simultaneous or in a sequence. It takes account of an agent’s attitudes to an act’s risk without weakening the standard of expected-utility maximization. The book’s theory of risk also grounds a justification of the risk-return evaluation of investments that finance advances, and a generalized version of this type of evaluation that a professional may use to advise clients about risks and that a government regulatory agency may use to make decisions about risks on behalf of the public.

The aim of appraisal theory in the psychology of emotion is to identify the features of the emotion-eliciting situation that lead to the production of one emotion rather than another². A model of emotional appraisal takes the form of a set of dimensions against which potentially emotion-eliciting situations are assessed. The dimensions of the emotion hyperspace might include, for example, whether the eliciting situation fulfills or frustrates the subject’s goals or whether an actor in the eliciting situation has violated a (...) norm. Richard Lazarus’s well-known model of emotional appraisal has six dimensions, and the regions of the resulting hyperspace that correspond to particular emotions are summarized by Lazarus as the ‘core relational themes’ of those emotions. Anger, for examples, is elicited by the core relational theme ‘a demeaning offence against me and mine’, sadness by ‘having experienced an irrevocable loss’ and guilt by ‘having transgressed a moral imperative’ (Lazarus, 1991).

New genetic technologies and their applications in biomedicine have important implications for social identities in contemporary societies. In medicine, new genetics is increasingly important for the identification of health and disease, the imputation of personal and familial risk, and the moral status of those identified as having genetic susceptibility for inherited conditions. There are also consequent transformations in national and ethnic collective identity, and the body and its investigation is potentially transformed by the possibilities of genetic investigations and modifications (including (...) the highly controversial terrains of reproductive technologies and the use of human embryos in biomedical research). The papers in this volume, drawn from an international array of authors, address these issues from a variety of national, disciplinary and empirical standpoints. An informative read for postgraduates and professionals in the fields of sociology, social anthropology, science and technology studies, and environmental studies, the chapters comprise empirically based and theoretically informed discussions of key sociological, anthropological, political and ethical issues. Using the resources of a wide range of social science disciplines to provide a comparative approach to complex issues, this superb collection explores the local and global consequences of the new genetics, and analyzes the social implications of these advances for identity formation in a period of rapid social change.

This article interprets emotional change as a transition in a complex dynamical sys- tem. We argue that the appropriate kind of dynamical system is one that extends recent work on how neural networks can perform parallel constraint satisfaction. Parallel processes that integrate both cognitive and affective constraints can give rise to states that we call emotional gestalts, and transitions can be understood as emotional ges- talt shifts. We describe computational models that simulate such phenomena in ways that show how dynamical (...) and gestalt metaphors can be given a concrete realization. (shrink)

In Decision Space: Multidimensional Utility Analysis, first published in 2001, Paul Weirich increases the power and versatility of utility analysis and in the process advances decision theory. Combining traditional and novel methods of option evaluation into one systematic method of analysis, multidimensional utility analysis is a valuable tool. It provides formulations of important decision principles, such as the principle to maximize expected utility; enriches decision theory in solving recalcitrant decision problems; and provides in particular for the cases in which (...) an expert must make a decision for a group of people. The multiple dimensions of this analysis create a decision space broad enough to accommodate all factors affecting an option's utility. The book will be of interest to advanced students and professionals working in the subject of decision theory, as well as to economists and other social scientists. (shrink)

One dimension of the controversy over whether evaluative properties are presented in perceptual content has general roots in the debate over whether perceptual content, in general, is rich or austere. I argue that we need to recognise a level of rich non-sensory perceptual content, drawing on experiences of chicken sexing and speech perception, to capture what our experience is like and our epistemic entitlements. In both cases (and many others), we are not conscious of the precise perceptual cues that are (...) the basis for discriminations and, thus, the characterisation of the phenomenal content of such experiences must go beyond sensory properties. Nevertheless, this point is arguably insufficient to establish the perception of evaluative properties. Their representation requires the subject to respond in certain ways. I discuss how this should go for the case of pain and then, in outline, for moral properties. (shrink)

It is commonly assumed that low-mass primordial black holes cannot constitute a significant fraction of the dark matter in our universe due to their predicted short lifetimes from the conventional Hawking radiation and evaporation process. Assuming physical black holes are nonsingular--likely due to quantum gravity or other high-energy physics--we demonstrate that a large class of nonsingular black holes have finite evaporation temperatures. This can lead to slowly evaporating low-mass black holes or to remnant mass states that circumvent traditional evaporation constraints. (...) As a proof of concept, we explore the limiting curvature hypothesis and the evaporation process of a nonsingular black hole solution in two-dimensional dilaton gravity. We identify generic features of the radiation profile and compare them with known regular black holes, such as the Bardeen solution in four dimensions. Remnant masses are proportional to the fundamental length scale, and we argue that slowly evaporating low-mass nonsingular black holes, or remnants, are viable dark matter candidates. (shrink)
