This paper outlines an account of concessive conditionals that rests on two main ideas. One is that the logical form of a sentence as used in a given context is determined by the content expressed by the sentence in that context. The other is that a coherent distinction can be drawn between a reading of ‘if’ according to which a conditional is true when its consequent holds on the supposition that its antecedent holds, and a stronger reading according to which a conditional is true when its antecedent supports its consequent. As we will suggest, the logical form of concessive conditionals can be elucidated by relying on this distinction.

关于让步条件句的逻辑形式

本文概述了基于两个主要思想的让步条件句。一是在给定上下文中使用的句子的逻辑形式由该句子在该上下文中表达的内容决定。另一个是可以在“如果”的解读之间做出连贯的区分，根据这种解读，当其后件成立时，条件为真，前提是其前提成立支持其结果。正如我们将建议的，让步条件句的逻辑形式可以依靠这种区别来阐明。
