简论徐敬德的认识论

韩国哲学家徐敬德,在韩国的性理学发展中起了巨大的推动作用.徐敬德的气哲学是对张载、邵庸和朱熹思想的继承和改造.格物致知,重思考,但不能正确处理感性认识与理性认识的关系,重视对"终极真理"的追求,但以自己无疑惑为最高境界,显然脱离了实践检验真理的标准.     

A circular-cone test for testing homogeneity against a simple tree order

Several methods exist for the problem of testing the equality of several treatments against the one-sided alternative that the treatments are better than the control. These methods include Dunnett's test, Bartholomew's likelihood-ratio test, the Abelson-Tukey-Schaafsma-Smid optimal-contrast test, and the multiple-contrast test of Mukerjee, Robertson, and Wright. A new test is proposed based on an approximation of the likelihood-ratio test of Bartholomew. This test involves using a circular cone in place of the alternative-hypothesis cone. The circular-cone test has excellent power characteristics similar to those of Bartholomew's test. Moreover, it has the advantages of being simpler to compute and may be used with unequal sample sizes.     

发展循环经济提升自然资源承载力

自然资源是社会经济发展不可缺少的支撑基础,没有资源的支撑,任何国家和地区的经济和社会都不可能有相应的发展。而资源可承载的社会经济发展能力是有限的,无论发达国家还是发展中国家,必须考虑到资源承载力的限制。随着我国经济持续快速增长,资源消耗增加,自然资源对我国经济增长的约束日趋明显,针对资源效率低下、承载力减弱的现状,我国将发展循环经济纳入"十一五规划纲要"。发展循环经济要求以环境友好的方式利用自然资源,实现经济活动向生态化转变,这无异于增加了资源的总量,提升了资源的承载能力。

Fuzzy epistemology: Decolonizing the social sciences

This article first argues that the social sciences need to be decolonized, as the current epistemologies and research methodologies are too narrowly based on the European and North American experiences and hence unable to adequately capture non-European experiences and realities. I then argue that decolonizing dominant social science epistemology means freeing it from its Aristotelian foundation. The next step undertaken is to discuss five non-Western epistemologies from West Africa, China, Melanesia, India, and South America. Building on the work of Jimi Adesina (2002), I find that all five share a fuzzy perception of reality, allowing for statements that are non-exclusive, non-discrete, and hence fuzzy. I propose an operationalization of these fuzzy epistemologies by applying Charles Ragin's Fuzzy Set Qualitative Comparative Analysis (fscqa).     

解蔽与成圣:荀子认识论新探

荀子明确将自然对象排斥于人的认识领域之外 ,而把认识对象规定为三位一体的“五经”、礼义和道。荀子的认识方法 ,一是通过具有理性思维能力的心灵 ,以静观的方式来认识对象 ;二是认识主体以“行”即践履的方式来把握对象。荀子的认识目标有两个层面 :其一是知性层面的“解蔽” ;其二是德性层面的“成圣”。从上述认识对象、认识方法、认识目标的具体规定来看 ,荀子的认识论是一种“社会道德认识论” ,而不是所谓的朴素唯物主义反映论

Another economy: towards a cultural dialectics between energy and society

The looming oil crisis, pollution, and climate change have pushed governments, corporations, and individuals to think of new policies, new objects/products and new manners to market them – usually under the label of “green economy” (or the shifting towards a sustainable economy).

The changes that are on the way as a result of the envisaged “green revolution” need a broad vision that couples the economy of energetic techniques with the related socio-cultural economy that is induced by, and at the same time reciprocally influences, the mere technical transformations.

Based on previous analysis of theories of socio-technological change and putting at its center the concept of subjectivation in social sciences, this article proposes a theoretical understanding of cultural shifts and their relationship with changes in the practices of production, transfer and use of energy.

First part presents a schema of subjectivation in triangulation, that links the biological level with the material culture and with the representational realm of normativities in our society. It will be developed through the example of electric vehicle as metaphor of the energetic transition. Through this understanding, second part deals with the modeling of the three items as a processual energetic system by using the concepts of surplus and expenditure. Within this frame, we show how disruptions in one of the poles of this model influences the others and bring about changes in the entire Anthropo-Social level. Third part proposes possible types of emerging subjectivities and advances the idea of extending the realm of consciousness to the energetic transfers and their potentiality.
