Experimental philosophy is often presented as a new movement that avoids many of the difficulties that face traditional philosophy. This article distinguishes two views of experimental philosophy: a narrow view in which philosophers conduct empirical investigations of intuitions, and a broad view which says that experimental philosophy is just the colocation in the same body of (i) philosophical naturalism and (ii) the actual practice of cognitive science. These two positions are rarely clearly distinguished in the literature about experimental philosophy, both pro and con. The article argues, first, that the broader view is the only plausible one; discussions of experimental philosophy should recognize that the narrow view is a caricature of experimental philosophy as it is currently done. It then shows both how objections to experimental philosophy are transformed and how positive recommendations can be provided by adopting a broad conception of experimental philosophy.  相似文献

The drastic increase of psychosocial ill health may point to the fact that current lifestyles produce longer lives, but with increased chronic disorders rather than greater health. Focus on current lifestyles, that is, on peoples' daily environments, are thereby warranted to develop models and methods for tracing health promoting factors inherent in people's daily participation and experiences. This study tests the content validity of OVal-9, an instrument based on the new concept; Occupational Value, among a sample of experts, students and clients. The result shows a good ability to assess the value that people experience in their daily occupations. We are convinced that measuring Occupational Value might be of importance in developing future strategies for intervention and prevention needed for the increasing incidence of mental ill-health.  相似文献

Abstract

This study assesses the relationship between friendship networks and academic performance among third graders from one school in Santiago, Chile. Longitudinal social network analysis (RSiena) was used to test whether friendship selection is driven by academic performance and if befriended peers tend to influence each other on their academic performance, including gender as a covariate. Results show a positive relationship between academic performance and number of friendship nominations received, and a higher probability of same-gender friendships. Students with higher academic achievement are more likely to be nominated as friends, especially by peers with lower academic achievement. These results suggest that elementary students value high performance as a desirable characteristic in their friends.  相似文献

By spanning the traditional scientific theories in the search for an epistemological home for information it is found that Physics (together with some inputs from Automata Theory) provides the criteria to identify the universals that characterize information processors. It is well known, however, that Physics and Mathematics alone are insufficient to answer some fundamental questions that arise in further speculations on the subject of information. It seems that Biology, in the realm of Evolution Theory and in terms of Natural Selection, is at present the only place able to offer the objective context required to properly characterize information as an object of scientific inquiry.

In this communication we intend to show, by establishing a working equivalence between the epistemological questions that should characterize a theory of information and those questions that characterize the science of Biology, how a science of information can be more objectively characterized. It is only by referring to selective pressures that we can solve the otherwise unanswerable philosophical question of whether it is possible to know if two players of a game are, in fact, playing the same game (the semantic question). It is also shown that it is possible, by using conventional criteria, to establish a phylogenesis of information processors from where we conclude that every information processor now existing in the universe (even computers and robots) has an ancestor that has once been a living being.

It is here suggested, however, that Biology is only a provisory epistemological ground for laying the foundations of an information science. A more inclusive theory should be founded on a generalization of the Theory of Evolution where mutation and natural selection should be described, not in terms of the characteristic media and mechanisms of biological systems, but of the identified universals of information processors.  相似文献

Based on a comparative study, this paper highlights and analyses commonalities and differences between an Oriental systems approach, WSR, and two Western counterparts, TOP and MMD. It is suggested that cultural differences among systems approaches might probably have been overshadowed by both commonalities between Western and Eastern traditions and differences within the same cultural tradition. It will be further proposed that by being more consciously open to and learning from each other, systems approaches in the East and the West may have more to offer for dealing with the complexity which confronts humankind.  相似文献

The history of science must be introduced onto the curriculum, scientific culture must be developed if the young are to receive a global, healthy understanding of science and technology.

The experiment pioneered by INSERM clubs is, from this point of view, exemplary.  相似文献

In recent decades cognitive-behavioral therapy (CBT) and decision science (DS) have emerged within the field of psychological science. Though these are two vastly different areas of study, they are similar in that they address human information processing, cognition, behavior, and the link between them. In this article, we provide brief summaries of CBT and decision science, discuss their similarities and differences, and discuss how future research can identify ways in which these fields can inform each other. Several CBT techniques that might be of use to the efforts of the decision science field to prevent cognitive biases are suggested. Research that integrates these two fields may lead to the improvement of both.  相似文献

David Hume argued that ought cannot be derived from is. That is, no set of facts, no amount of scientific knowledge, is by itself sufficient to urge us to action. Yet generations of well-meaning scientists (more and more as secular influences grow in the West) seem to have forgotten Hume''s words of wisdom. All motivated action depends ultimately on beliefs that cannot be proved by the methods of science, that is, on faith.  相似文献

L. Ron Hubbard created in Scientology an immense landscape of alternative worlds, realities, and possibilities. Scientology cosmology, mythology, and eschatology are inescapably linked to galactic events and Hubbard's retelling of human history is replete with science-fiction tropes – many of which found popularity in the early science-fiction tradition to which he belonged. In his therapeutic and religious teachings, Hubbard proposed a complex narrative that re-defined the essence of self and society in relation to the cosmos. For Scientologists, the fantastic becomes mundane as they position themselves within a vast and heavy quest to reshape themselves, the rest of humanity, and, for some, the entire universe. Understood within the science-fiction context from which Scientology emerged, one can better understand the grand nature of Hubbard's proposals as belonging to a specific tradition within the genre – namely, space opera. Consequently, this article analyses Hubbard's propositions using space-opera concepts, and argues that Hubbard re-defined a unique tradition in the course of creating a new reality.  相似文献
