I agree with this criticism, but also think that context is required in order to determine the presupposition included in a complex sentence. To show the context role in fixing the utterance truth-conditions in those cases, this paper introduces the Kripkean anaphoric account on presuppositions (section 2), and then criticizes this approach because it is very restrictive (section 3). The paper concludes that to solve those difficulties, one should appeal to a two-dimensional framework, including a new parameter that focuses on the sentence according to the concrete features of the context: the speaker's point of view (section 4).展开更多

The partial Kripke structures were used for partial state spaces model checking, which is a new technique to solve problems of state explosion. This paper extended the partial Kripke structure with fairness conditions by defining a partial fair Kripke structure, and a 3 valued fair CTL(Computation Tree Logic) semantics correspondingly. It defines a fair preorder between partial Kripke structures that preserves fairness and is akin to fair bisimulation. In addition, a pertinent theorem is also given, which indicates the relationship between the partial state spaces and the more complete one by illustrating the characterizations of states in the partial fair structure in terms of CTL formulae.展开更多

Through an analysis of Kripke's critique of Searle's views, I reach the conclusion that Kripke;s criticism is based upon a misinterpretation of Searle's ideas. Searle tried to answer the question "what is the object named as such?" That is different from the question that Kripke attributed to the descriptivists, i.e. "what are the necessary criteria to identify the referent of a name in every possible world?" I think Searle's question is also a question that Kripke's Causal Theory of Names has to answer, i.e. how a name transmits through a linguistic community.展开更多

I regard the case of the "hexagram" names as being quite representative of the "double-reference" semantic-syntactic structure of referring names. I thus explore how the general morals drawn from this account of "hexagram" names can engage two representative approaches, the Fregean and Kripkean ones, and contribute to our understanding and treatment of the issue of reference.展开更多
