Much research in the last two decades has demonstrated that human responses deviate from the performance deemed normative according to various models of decision making and rational judgment (e.g., the basic axioms of utility theory). This gap between the normative and the descriptive can be interpreted as indicating systematic irrationalities in human cognition. However, four alternative interpretations preserve the assumption that human behavior and cognition is largely rational. These posit that the gap is due to (1) performance errors, (2) computational (...) limitations, (3) the wrong norm being applied by the experimenter, and (4) a different construal of the task by the subject. In the debates about the viability of these alternative explanations, attention has been focused too narrowly on the modal response. In a series of experiments involving most of the classic tasks in the heuristics and biases literature, we have examined the implications of individual differences in performance for each of the four explanations of the normative/descriptive gap. Performance errors are a minor factor in the gap; computational limitations underlie non-normative responding on several tasks, particularly those that involve some type of cognitive decontextualization. Unexpected patterns of covariance can suggest when the wrong norm is being applied to a task or when an alternative construal of the task should be considered appropriate. Key Words: biases; descriptive models; heuristics; individual differences; normative models; rationality; reasoning. (shrink)

ABSTRACT In this paper we compare philosophical and contemporary psychological approaches to mental handicap. Careful comparison between the disciplines reveals major differences and indicates that much further work is needed which would be fruitful for both sides. The two disciplines concentrate on different questions: philosophy tends to look chiefly at mental handicap in relation to issues of personhood and is not very clear about what mental handicap is; psychology on the other hand is much more specific about mental handicap, but (...) shows little concern with critically examining value issues. Our main intention is to explore the different ways in which mental handicap is defined and seen as a class. We conclude that class definition embodies a significant normative component and a large element of social construction. To ignore this and attempt to make normative judgements on the basis of class membership is thus highly problematic. Since within philosophy, these normative issues are often discussed in terms of personhood, this category is also critically examined and the conclusion is reached that it too has normative and social components which can lead to ethically dubious judgements being made about ‘the mentally handicapped’.

I want to argue for the importance of the notion human being in ethics. Part I of the paper presents two different sorts of argument against treating that notion as important in ethics. A. Here is an example of the first sort of argument. What makes us human beings is that we have certain properties, but these properties, making us members of a certain biological species, have no moral relevance. If, on the other hand, we define being human in terms (...) which are not tied to biological classification, if we treat as the properties which make us human the capacities for reasoning or for self-consciousness, then indeed those capacities may be morally relevant, but if they are morally significant at all, they are significant whether they are the properties of a being who is a member of our species or not. And so it would be better to use a word like ‘person’ to mean a being that has these properties , to bring out the fact that not all human beings have them and that non-human beings conceivably might have them.

La mort, le temps : deux notions fondamentales qui parcourent toute l'œuvre d'Emmanuel Lévinas et qui, pour la première fois, sont ici précisément thématisées. À partir d'un dialogue serré avec deux contemporains d'envergure, Heidegger et Bloch, et quelques-uns des grands penseurs de la tradition, Aristote, Hegel et Kant notamment, le philosophe développe une formidable méditation qui propose d'éclairer les rapports noués dans la réflexion occidentale entre la mort et le temps. Ainsi, à la démarche heideggerienne qui entend penser le temps (...) à partir de la mort, il oppose l'idée que l'on peut inscrire la mort dans le tissu du temps. (shrink)

Drawing on the work of Scheler, Heidegger, Merleau-Ponty, Husserl and Sartre, this article presents an overview of some of the diverse approaches to intersubjectivity that can be found in the phenomenological tradition. Starting with a brief description of Scheler's criticism of the argument from analogy, the article continues by showing that the phenomenological analyses of intersubjectivity involve much more than a 'solution' to the 'traditional' problem of other minds. Intersubjectivity doesn't merely concern concrete face-to-face encounters between individuals. It is also (...) something that is at play in simple perception, in tool-use, in emotions, drives and different types of self-awareness. Ultimately, the phenomenologists would argue that a treatment of intersubjectivity requires a simultaneous analysis of the relationship between subjectivity and world. It is not possible simply to insert intersubjectivity somewhere within an already established ontology; rather, the three regions 'self', 'others', and 'world' belong together; they reciprocally illuminate one another, and can only be understood in their interconnection.
