Doing well enough: Toward a logic for common-sense morality

On the traditional deontic framework, what is required (what morality demands) and what is optimal (what morality recommends) can't be distinguished and hence they can't both be represented. Although the morally optional can be represented, the supererogatory (exceeding morality's demands), one of its proper subclasses, cannot be. The morally indifferent, another proper subclass of the optional-one obviously disjoint from the supererogatory-is also not representable. Ditto for the permissibly suboptimal and the morally significant. Finally, the minimum that morality allows finds no place in the traditional scheme. With a focus on the question, “What would constitute a hospitable logical neighborhood for the concept of supererogation?”, I present and motivate an enriched logical and semantic framework for representing all these concepts of common sense morality.     

A Propositional Dynamic Logic with Qualitative Probabilities

This paper presents an -completeness theorem for a new propositional probabilistic logic, namely, the dynamic propositional logic of qualitative probabilities (D Q P), which has been introduced by the author as a dynamic extension of the logic of qualitative probabilities (Q P) introduced by Segerberg.     

Prolegomena of a Logic of Causality and Dynamism

We present in this article a new logical system inspired from linear logic. This system is designed in order to express causality and dynamism. The cut elimination theorem holds for this logic. Examples of applications are given.     

《易经》:人类科学思维和审美思维方式的精典阐释

一本诞生于五千年前的中国古书《易经》,已经包含着深刻的现代科学数理逻辑原理,且与美学的审美逻辑原理互为支持、互为表里,使这两大类本来被认为水火不相容的领域及其独具的思维方式得到了高度完善统一的阐释。从这样的角度来看《易经》,也许会有助于目前心理学界对思维方式及逻辑问题的研究,拓开一条崭新的思路。     

影响说谎行为的情境因素——基于自我概念维持理论的视角

情境因素会影响人们的说谎行为。本文基于自我概念维持理论的视角,从个体内部状态（自我控制资源、宗教表征/道德观念启动）和外部因素（金钱奖励、人际因素）两方面介绍情境因素对说谎行为的影响,并指出未来研究应关注自我觉察水平这一情境因素以及情境因素影响说谎行为的心理机制和神经机制。     

公正世界信念与跨情境动机效应

采用2（公正世界信念状态：公正vs不公正）×2（中奖者的个性品质：正向vs负向）被试间实验设计,以在校大学生为被试,考察公正世界信念是否具有跨情境动机效应。结果发现：预先激活的公正世界信念状态迁移到了回忆不同个性品质中奖者奖金数额这个不同情境中,影响了人们的记忆。表明公正世界信念存在跨情境动机效应。
