An analysis of a predicate normally takes the form of a condition that is both necessary and sufficient for the predicate's application. Here I consider the idea, due originally to Friedrich Waismann, that semantic analyses might include conditions that are defeasible, and so allow for exceptions. Analyses of this sort can be expressed in nonmonotonic logic, a post-Waismann development. I'll argue that defeasibility makes analysis tractable, without making it trivial. I'll also show that a defeasible account of vague predicates can predict our intuitions about particular cases (for instance, that a seven-foot person counts as tall) without drawing artificial boundaries.

语义原因

谓词的分析通常采用对于谓词的应用来说既必要又充分的条件的形式。在这里,我考虑了最初由 Friedrich Waismann 提出的想法,即语义分析可能包括可废止的条件,因此允许例外。此类分析可以用非单调逻辑来表达,这是后魏斯曼的发展。我认为可废止性使分析变得容易处理,但又不会使其变得微不足道。我还将证明,对模糊谓词的可废止的描述可以预测我们对特定情况的直觉(例如,七英尺高的人算作高),而无需划定人为界限。
