论文摘要
本文讨论了艾伦·吉布巴德（Allan Gibbard）所谓的指示性有条件的所谓微不足道结果的范围和意义，表明，如果条件操作员满足进口出口的范围，则具有超级经典性，并且比材料有条件的有条件更强，那么它必须倒入条件材料的条件下。 Gibbard的结果是为了对指示性有条件的真实功能说明构成困境：放弃进出口或包含两值分析。我们表明，基于Reichenbach和De Finetti的想法，即有错误的先决条件是不确定的，可以避免这种困境的条件逻辑。在这种逻辑中，进出口远处和真相 - 功能性无关。我们在Gibbard的证明中揭示了一些隐含的假设，并讨论了由于Branden Fitelson而对Gibbard结果的最新概括。
This paper discusses the scope and significance of the so-called triviality result stated by Allan Gibbard for indicative conditionals, showing that if a conditional operator satisfies the Law of Import-Export, is supraclassical, and is stronger than the material conditional, then it must collapse to the material conditional. Gibbard's result is taken to pose a dilemma for a truth-functional account of indicative conditionals: give up Import-Export, or embrace the two-valued analysis. We show that this dilemma can be averted in trivalent logics of the conditional based on Reichenbach and de Finetti's idea that a conditional with a false antecedent is undefined. Import-Export and truth-functionality hold without triviality in such logics. We unravel some implicit assumptions in Gibbard's proof, and discuss a recent generalization of Gibbard's result due to Branden Fitelson.
