儒家道德哲学及其审美境界

中国审美文化从本质意义上说是一种与天地亲和的生命文化,儒家传统最基本的特征就是肯定天人之间所具有本体论的一致性,因此儒家不从信仰出发来解释生命的伟大德行,而是从生生不息的生命本身来观照道德的本源。儒家作为生命的实践者,凭借其内在的生命力量,通过澄心静虑、心游目想,通过直观感悟、直觉体悟,以达到人生境界与审美境界的合一。这一过程既是道德主体的一种心理体验,更是道德主体通过一种外在践履工夫的求证。     

证明与印证

<论确定性>是维特根斯坦生前留下的最后手稿,被研究者推为自<纯粹理性批判>以来知识论领域最重要的贡献.本文在厘清"证明"与"印证"之概念区分的基础上,考察了<论确定性>的论证结构,把维氏的洞见理解为:信念的确定性在于普遍印证,而非完备证明.     

客体和空间工作记忆中三维图形的特征加工时程

采用单探测变化觉察范式，对三维图形的特征在客体和空间工作记忆中的加工时程进行了探讨。实验一的材料是由不同颜色和形状组成的规则立体图形。实验二的材料是由不同颜色和图案组成的六棱柱。实验结果显示：（1）客体和空间工作记忆绩效均随识记项目数的增加而显著下降；（2）随着刺激呈现时间的延长，客体工作记忆绩效显著提高，空间工作记忆绩效无明显增加；且在三种呈现时间条件下，空间工作记忆绩效均高于客体工作记忆；（3）三维图形中颜色特征的检测绩效优于形状、图案和特征捆绑。这些结果表明，视觉工作记忆中三维图形的特征加工存在显著的时程效应，空间位置加工最早完成，其次是颜色加工，然后是形状与颜色-形状的捆绑，最后是图案与颜色-图案的捆绑。     

Three Dogmas of Normativity

In this article, I identify and critically examine 3 dogmas of normativity that support a commonly accepted ‘Passivist View' of rational agency. I raise some questions about these dogmas, suggest what we should believe in their place, and moot an alternative ‘Activist View' of what it is to be a rational agent that grows out of rejection of the 3 dogmas. Underwriting the dogmas and the Passivist View, I suggest, is a deeply held but mistaken assumption that the normative domain is fundamentally akin to the nonnormative domain. Once we allow that the normative may be fundamentally unlike the nonnormative in certain key ways, a shift in our thinking about what it is to be rational becomes possible. I end by considering some implications of this paradigm shift in rationality from the passive to the active for various applied matters.     

Positron brain imaging--normal patterns and asymmetries

Regional brain physiology was investigated in 11 normal resting right-handed subjects using positron emission tomography. Cerebral blood flow was studied in all subjects. Cerebral oxygen metabolism was studied in six subjects, and cerebral glucose metabolism was also studied in one subject. In five subjects, physiological activity was higher in left frontotemporal regions than right. These findings may be related to structural cerebral asymmetries or to activation of brain language centers.
