Actions and Events: Some Semantical Considerations

Since the publication of Davidson's influential article 'The Logical Form of Action Sentences', semantical considerations are widely thought to support the doctrine that actions are events. I shall argue that the semantics of action sentences do not imply that actions are events. This will involve defending a negative claim and a positive claim, as well as a proposal for how to formalize action sentences. The negative claim is that the semantics of action sentences do not require that we think of actions as events, even if these sentences are best formalized in the manner that Davidson himself favours . The positive claim is that the simplest way of formalizing actions sentences which captures all and only licit inferences requires quantification only , over the results of actions. If this is right, then the argument from semantics evaporates, and the claim that actions are events needs to be freshly argued for – or against.     

Idols and Demons: On Discerning the Spirits

This article elaborates on the distinction between two spiritual ailments, which can be properly identified as idolatry and demonry. They represent opposite but complementary age–long phenomena still relevant to the analysis of the contemporary spiritual situation in explaining disorders of the soul as well as cultural derangement. The text suggests that the church as the spiritual community is the locus for the discernment of the spirit and that in its two distinguishing foundational and functional features (the proclamatory function and the communion function) it is molded precisely to confront both idols and demons.     

试论语义悖论的弗完全理论

弗完全理论通过限制排中律的使用,弱化经典逻辑,采用非经典的三值语言来处理语义悖论,最终使得形式语言能够一致地包含自身的真谓词。文中我们讨论了弗完全理论的两种基本形式——基础的弗完全理论和高级的弗完全理论。基础的弗完全理论引入了＂真值空缺＂的思想,认为句子除了真假之外还有＂既不真也不假＂的第三值,像说谎者这样的语义悖论语句就落在真假之空缺中,该理论借助于对不动点的归纳构造过程证明了形式语言中真谓词的存在性。高级弗完全理论在前者的基础上引入一个适当的条件句,定义了一个＂更强的真＂,发展出了既满足真的素朴模式又具有不动点解释的、一致的高级弗完全理论。     

Semantical analysis of predicate logics without the contraction rule

In this paper, a semantics for predicate logics without the contraction rule will be investigated and the completeness theorem will be proved. Moreover, it will be found out that our semantics has a close connection with Beth-type semantics.     

Harnessing Our Inner Angels and Demons: What We Have Learned About Want/Should Conflicts and How That Knowledge Can Help Us Reduce Short-Sighted Decision Making

ABSTRACT— Although observers of human behavior have long been aware that people regularly struggle with internal conflict when deciding whether to behave responsibly or indulge in impulsivity, psychologists and economists did not begin to empirically investigate this type of want/should conflict until recently. In this article, we review and synthesize the latest research on want/should conflict, focusing our attention on the findings from an empirical literature on the topic that has blossomed over the last 15 years. We then turn to a discussion of how individuals and policy makers can use what has been learned about want/should conflict to help decision makers select far-sighted options.     

Altering Beliefs About the Importance of Strategy: An Attributional Intervention1

The study reported in this paper describes an attributional intervention designed to change maladaptive beliefs for failure from uncontrollable causes to a lack of strategy attribution. Rather than an academic setting, the context for this research was the heath field and subjects were 52 physical therapists experiencing role strain (failure) in their professional interactions with physicians. Half of these health professionals were randomly assigned to a 3-week intervention where they were trained to attribute their failures to poor choice of strategy, rather than to uncontrollable factors such as low ability or physician bias. Relative to a control group, subjects who participated in the attribution retraining program were more likely to endorse strategy attributions and expected greater success in their interactions with physicians at the conclusion of the intervention. At a 6-month follow-up, trained subjects also received more actual job promotions. These findings have implications for attribution retraining to strategy in a variety of domains.

Second-Order Quantifier Elimination in Higher-Order Contexts with Applications to the Semantical Analysis of Conditionals

Second-order quantifier elimination in the context of classical logic emerged as a powerful technique in many applications, including the correspondence theory, relational databases, deductive and knowledge databases, knowledge representation, commonsense reasoning and approximate reasoning. In the current paper we first generalize the result of Nonnengart and Szałas [17] by allowing second-order variables to appear within higher-order contexts. Then we focus on a semantical analysis of conditionals, using the introduced technique and Gabbay’s semantics provided in [10] and substantially using a third-order accessibility relation. The analysis is done via finding correspondences between axioms involving conditionals and properties of the underlying third-order relation. Presented by Wojciech Buszkowski
