论罗尔斯的政治义务理论

政治义务是政治哲学的核心问题。哈特首先用“相互限制原则”来解释政治义务,这一原则为罗尔斯所继承并加以修正。鉴于该原则存在的诸多问题,罗尔斯在《正义论》中削减了它在政治义务的道德证明中的作用,而诉诸正义的自然责任原则。这个原则仍然受到来自多方面的批评,许多罗尔斯的追随者对这些批评作了回应。罗尔斯从公平游戏原则到自然责任原则的转变反映了他对契约论不同的态度。     

The Repeatability Argument and the Non-Extensional Bundle Theory

I present a new objection to Bundle Theory. The objection rests on the repeatability of universals, and targets every version of Bundle Theory that assumes that concrete particulars constituted by the same universals are numerically identical. The only way that bundle theorists can elude this objection is to admit the possibility of distinct bundles constituted by the same universals. If even this view is untenable, then Bundle Theory as such is hopeless. Finally, I show how the present inquiry reshapes the dialectical relationship between Bundle Theory and the principle of Identity of Indiscernibles.     

Sound Body,Sound Mind? The Interrelation Between Health Change and Personality Change in Old Age

Personality development is characterized by increasing maturation, that is, people become more conscientious, agreeable and emotionally stable as they age. In late life, however, these trends seem to be reversed. Because many changes and transitions in older age are related to health, we investigated correlated changes in health problems and personality traits, the sources of health changes in later life and the directionality of effects. Our sample consisted of older adult twins, aged 64–85 years at time 1 (n = 410; 135 male/275 female; 134 monozygotic/63 dizygotic twin pairs), assessed at two different time points about five years apart, and we ran bivariate latent change and latent change twin model analyses. Increasing health problems were associated with decreases in agreeableness, extraversion, emotional stability and conscientiousness. Changes in health problems were only due to environmental influences, implying that the association between health and personality changes was exclusively environmental. Directional effects were largely absent, but health and personality were significantly related at the second measurement occasion (age 69–89 years). Our results support the link between health change and personality change in late life and spark the assumption of normative personality adaptations to deterioration of health status as a means of developmental regulation.

儿童在指物交流中对量的交流准则的掌握

采用指物交流实验方法,同时从听和说两方面考察了儿童在指物交流中对量的准则的掌握情况。被试是幼儿园大班至小学三年级共４个年级组的８０名儿童。结果显示：听、说两种能力的发展不同步,说滞后于听．在听的方面,小学一年级组已能基本按量的准则完成任务,而在说的方面,直到三年级才能较好完成任务．在说的操作中普遍出现信息缺漏和信息冗余两类错误,各组内两类错误在总错误数中的比率随年级上升而变化。低年级组信息缺漏高于信息冗余,三年级组则信息冗余高于信息缺漏。
