IMAGINATION'S GRIP ON SCIENCE

Abstract: In part because “imagination” is a slippery notion, its exact role in the production of scientific knowledge remains unclear. There is, however, one often explicit and deliberate use of imagination by scientists that can be (and has been) studied intensively by epistemologists and historians of science: thought experiments. The main goal of this article is to document the varieties of thought experimentation, not so much in terms of the different sciences in which they occur but rather in terms of the different functions they fulfil. I argue that thought experimentation (and hence imagination) plays a role not only in theory choice but in singular causal analysis and scientific discovery as well. I pinpoint, moreover, some of the rules governing the use of thought experiments in theory choice and in singular causal analysis, that is, some of the criteria they should meet in order to fulfil those functions successfully.     

EMPLOYEES' CHALLENGING JOB EXPERIENCES AND SUPERVISORS' EVALUATIONS OF PROMOTABILITY

Promotability evaluations are important for individuals' career development and organizations' human resource management practices. Nevertheless, little empirical research has addressed predictors of promotability evaluations, and the studies that have, have often focused on current job performance and fixed, nonbehavioral predictors. This study takes a more behavioral approach, and investigates whether besides how one performs (i.e., job performance) what one performs also serves as an indicator of promotability. Specifically, we examine the relationship between employees' challenging job experiences and supervisors' evaluations of employees' promotability over and above employees' current job performance. Results from 3 field studies, sampling different types of employees via different measures, consistently showed that challenging job experiences explained incremental variance in supervisory and organizational evaluations of promotability over and above current job performance and job tenure.     

PATTERNS OF INTERDEPENDENCE IN WORK TEAMS: A TWO-LEVEL INVESTIGATION OF THE RELATIONS WITH JOB AND TEAM SATISFACTION

A questionnaire study in 17 school and 24 engineering teams examined affective reactions to task and goal interdependence at the group and individual level of analysis. Group-level task interdependence was positively related to group members' job and team satisfaction. Within-group differences in the degree of task interdependence were unrelated to affective responses. Interactions revealed that within-group task interdependence is positively related to both job and team satisfaction only if the degree of goal interdependence in the work team is high.     

What Moore's Paradox Is About

On the basis of arguments showing that none of the most influential analyses of Moore's paradox yields a successful resolution of the problem, a new analysis of it is offered. It is argued that, in attempting to render verdicts of either inconsistency or self-contradiction or self-refutation, those analyses have all failed to satisfactorily explain why a Moore-paradoxical proposition is such that it cannot be rationally believed. According to the proposed solution put forward here, a Moore-paradoxical proposition is one for which the believer can have no non-overridden evidence. the arguments for this claim make use of some of Peter Klein's views on epistemic defeasibility. It is further suggested that this proposal may have important meta-epistemological implications.     

THE MYTH OF CARTESIAN QUALIA

Abstract:  The standard view of Cartesian sensations (SV) is that they present themselves as purely qualitative features of experience (or qualia). Accordingly, Descartes' view would be that in perceiving the color red, for example, we are merely experiencing the subjective feel of redness rather than seeming to perceive a property of bodies. In this paper, I establish that the argument and textual evidence offered in support of SV fail to prove that Descartes held this view. Indeed, I will argue that there are textual and theoretical reasons for believing that Descartes held the negation of SV. Qualia aren't Descartes' legacy.     

Brief Therapy: Focused Solution Development

This article describes the form of brief therapy developed at the Brief Family Therapy Center. We have chosen a title similar to Weakland, Fisch, Watzlawick, and Bodin's classic paper, "Brief Therapy: Focused Problem Resolution" (20) to emphasize our view that there is a conceptual relationship and a developmental connection between the points of view expressed in the two papers.
