现代社会生活的生产实践表明,分工是交换的前提,交换是分工的实现,这就是现代社会活动的全部内容和过程。在此事实基础上构建的市场经济体制,其管理理念内含着丰富的伦理意蕴[1]。本文首先分析阐述了市场经济信用体系的建立是市场经济体制内在规律的必然要求,揭示了“信用”是承诺者之间能量均衡与博弈的结果,既具有丰富的道德理性又具有明显的功利要求。文章进而通过对信用体系维护的动力因素及其与市场主体行为的相关性进行比较研究后指出:政府在参与市场经济活动中要坚持“有所为,有所不为”,应把政府置于经济利益之外,使之具有超脱于市场各成员的地位;同时,信用体系的创立和维护并不必然由政府主导,而是市场经济环境中公共合意选择的必然结果。 相似文献

René Descartes and William James had “body first” theories of the passions or emotions, according to which sensory stimulation causes a bodily response that then causes an emotion. Both held that this bodily response also causes an initial behavioral response (such as flight from a bear) without any cognitive intervention such as an “appraisal” of the object or situation. From here they differ. Descartes proposed that the initial processes that produce fear and running are entirely mechanical. Even human beings initially run from the bear as a result of physiological processes alone, without mental contribution. These physiological processes also cause a mental passion, which is a cognitive representation of the situation (as regards novelty, benefit, or harm), and which motivates the will to continue the behavior already in progress. According to James, emotions are caused by instinctive bodily responses that are triggered by noncognitive but nonetheless conscious perceptual states. Emotions are bare feelings of internal physiological stirrings that accompany an instinctual response that has evolved through Darwinian natural selection. Jamesian emotions initially have no motivational or cognitive content, which they subsequently acquire through learning. The methodological legitimacy of comparing these positions across the centuries is defended, and the two theories are compared to recent theories. 相似文献

Computational modeling of the brain holds great promise as a bridge from brain to behavior. To fulfill this promise, however, it is not enough for models to be ‘biologically plausible’: models must be structurally accurate. Here, we analyze what this entails for so-called psychobiological models, models that address behavior as well as brain function in some detail. Structural accuracy may be supported by (1) a model's a priori plausibility, which comes from a reliance on evidence-based assumptions, (2) fitting existing data, and (3) the derivation of new predictions. All three sources of support require modelers to be explicit about the ontology of the model, and require the existence of data constraining the modeling. For situations in which such data are only sparsely available, we suggest a new approach. If several models are constructed that together form a hierarchy of models, higher-level models can be constrained by lower-level models, and low-level models can be constrained by behavioral features of the higher-level models. Modeling the same substrate at different levels of representation, as proposed here, thus has benefits that exceed the merits of each model in the hierarchy on its own. 相似文献

This paper presents and defends the view that reinforcement and natural selection are selection processes, that selection processes are neither mechanistic nor teleological, and that mentalistic and vitalistic processes are teleological but not mechanistic. The differences between these types of processes are described and used in discussing the conceptual and methodological significance of “selection type theories” and B. F. Skinner's radical behaviorist view that “operant behavior is the field of intention, purpose, and expectation. It deals with that field precisely as the theory of evolution has dealt with another kind of purpose” (1986, p. 716). The antimentalism of radical behaviorism emerges as a post-Darwinian extension of Francis Bacon's (and Galileo's) influential view that “[the introduction of final causes] rather corrupts than advances the sciences” (Bacon, 1905, p. 302). 相似文献

This article responds to Stanley J. Grenz's Templeton Lecture, “Why Do Theologians Need to Be Scientists?” published in the June 2000 issue of Zygon (Grenz 2000). In the first part I outline my reasons for finding the kind of theological reflections in which Grenz engages worthy of attention by noting my disagreement with the view that a sufficient response to theological issues can be formulated on the basis of an examination of our biological nature. I assert, in that connection, the autonomy of reason as a way of investigating and understanding the world. In the second part I respond directly to Grenz by explaining my disagreement with the postmodern critique of science upon which he relies and his adherence to Christian eschatology as an answer to the conundrums into which, he posits, we are drawn as a result of that critique. I note that I agree with Grenz, however, that the activity of valuing is necessarily a forward‐looking Godlike endeavor that is not derivable from science. In the third part I suggest that we must be open to the investigation of the possible existence of an objective realm of value and that, in any case, rejection of the postmodern critique of science in many cases pro‐vides a sound basis for the disciplined resolution of factual questions that frequently lie at the base of disagreements about values. 相似文献

This study examines the developmental influences of occupational environments on personality traits from childhood to adulthood. We test aspects of a theory of vocational and personality development, proposing that traits develop in response to work experience following corresponsive and noncorresponsive mechanisms. We describe these pathways in the context of situations of vocational gravitation and inhabitation. In a sample from the Hawaii personality and health cohort (N = 596), we examined associations of childhood and adulthood personality traits, with occupational environments profiled on the RIASEC model. Mediations tests confirmed that work influenced personality development from childhood to adulthood for Openness/Intellect. We observed multiple reactivity effects of occupation environments on adulthood traits that were not associated with corresponding selection effects. 相似文献
