This paper examines the relationship between Savage's sure thing principle and the value of information. We present two classes of results. First, we show that, under a consequentialist axiom, the sure-thing principle is neither sufficient nor necessary for perfect information to be always desirable: specifically, under consequentialism, the sure thing principle is not implied by the condition that perfect information is always valuable; moreover, the joint imposition of the sure thing principle, consequentialism and either one of two state independence axioms (...) does not imply that perfect information is always desirable. Second, we demonstrate that, under consequentialism, the sure thing principle is necessary for a nonnegative value of possibly imperfect information (though of course the principle is still not sufficient). One implication of these results is that the sure thing principle, under consequentialism, plays a somewhat different role in ensuring dynamic consistency in decision making under uncertainty than does the independence axiom in decision making under risk.

Structural equations have become increasingly popular in recent years as tools for understanding causation. But standard structural equations approaches to causation face deep problems. The most philosophically interesting of these consists in their failure to incorporate a distinction between default states of an object or system, and deviations therefrom. Exploring this problem, and how to fix it, helps to illuminate the central role this distinction plays in our causal thinking.

By applying diverse approaches to study the Aztec gods, light can be shed on different aspects of their personalities. In this article the cognitive theory of conceptual blending, developed by Fauconnier and Turner, is applied. In this perspective the functioning of the human mind is viewed as being grounded on the constant blending of mental spaces, a process that, in turn, makes new mental spaces emerge. After briefly reviewing the attempts to apply this theory to the ritual domain in general, (...) I consider two types of Aztec rituals, one dedicated to the rain god Tlaloc, and the other to Xochiquetzal, the goddess of seduction. I show the importance of the compression of time in the blending process that condenses three moments: mythical time, ritual time and the immediate future. The capability of the gods to subvert the lineal passage of time and to compress past, present and future stands out as a one of the chief characteristics highlighting the advantages found by applying Blending-Theory.

This article argues that phenomenological sociology has great potential to provide a strong theoretical support to the Sociocognitive Approach in Critical Discourse Studies. SCA is interested in the interconnections between knowledge, discourse and society while placing subjectivity in the centre of its framework. It looks into the correlative relationship between personal- and socially shared knowledge, and the significance of these correlations to discourse production and interpretation. Analogously, phenomenological sociology explores the interrelated structures of subjectivity, knowledge and the social world. It (...) systematically analyses the conditions and forms of intersubjective understanding and the mutually constitutive relationship between subjective- and objective knowledge. Given the considerable overlap between the subject matter of phenomenological sociology and that of SCA, the purpose of the article is to draw the attention of critical discourse analysts to a neglected but extremely resourceful field. Following a brief introduction to SCA, the article will address some of SCA’s key concepts in conjunction with the phenomenological-sociological insight. (shrink)
