Abstract: In Wittgenstein on Rules and Private Language, Kripke's Wittgenstein argues that it is possible for individuals in communities to speak a language and otherwise follow rules, but impossible for a single, conceptually isolated individual to do so. I show that the roots of the argument lie in his general account of the legitimacy of practices, and that he actually argues for two distinct conclusions: (a) solitary individuals cannot have useful practices of rule‐following and (b) solitary individuals cannot place substantive restrictions on their own behavior. I show that if it is, in fact, possible for individuals in communities to use language and follow rules, then both of Kripke's Wittgenstein's anti‐solitary language arguments fails; and, furthermore, that his general account not only fails to exclude the possibility of solitary language‐use and rule‐following, it actually guarantees their possibility. 相似文献

There is substantial evidence of detrimental psychological sequelae following disasters, including terrorist attacks. The effect of these events on extreme responses such as suicide, however, is unclear. We tested competing hypotheses about such effects by employing autoregressive integrated moving average techniques to model the impact of September 11 and the Oklahoma City bombing on monthly suicide counts at the local, state, and national level. Unlike prior studies that provided conflicting evidence, rigorous time series techniques revealed no support for an increase or decrease in suicides following these events. We conclude that while terrorist attacks produce subsequent psychological morbidity and may affect self and collective efficacy well beyond their immediate impact, these effects are not strong enough to influence levels of suicide mortality. 相似文献

As the complexity of the challenges presented by our interactions with our planet continues to grow, we must develop new modes
of knowledge production. In these modes, distinctions between multidisciplinary and inter-disciplinary activities and processes
have renewed importance. There are at least two distinct types of interdisciplinary activities distinguished by the disciplinary
breadth they attempt to bridge. In the narrow case, reductionist processes reveal a common underlying principle or process
which can serve as a Rosetta stone. In the broad case, no such common arbiter exists. Investigators must develop integrating
vocabulary in the context of the full breadth of their work.
His primary activities are the fostering of university-wide interdisciplinary research and curriculum programs focused on
global change with the goal of developing Columbia into a world leader in issues related to global stewardship. 相似文献

This essay presents a philosophical and computational theory of the representation of de re, de dicto, nested, and quasi-indexical belief reports expressed in natural language. The propositional Semantic Network Processing System (SNePS) is used for representing and reasoning about these reports. In particular, quasi-indicators (indexical expressions occurring in intentional contexts and representing uses of indicators by another speaker) pose problems far natural-language representation and reasoning systems, because—unlike pure indicators—they cannot be replaced by coreferential NPs without changing the meaning of the embedding sentence. Therefore, the referent of the quasi-indicator must be represented in such a way that no invalid coreferential claims are entailed. The importance of quasi-indicators is discussed, and it is shown that all four of the above categories of belief reports can be handled by a single representational technique using belief spaces containing intensional entities. Inference rules and belief-revision techniques for the system ore also examined. 相似文献
