This essay calls attention to a set of linguistic interactions between counterfactual conditionals, on one hand, and possibility modals like could have and might have, on the other. These data present a challenge to the popular variably strict semantics for counterfactual conditionals. Instead, they support a version of the strict conditional semantics in which counterfactuals and possibility modals share a unified quantificational domain. I’ll argue that pragmatic explanations of this evidence are not available to the variable analysis. And putative counterexamples to the unified strict analysis, on careful inspection, in fact support it. Ultimately, the semantics of conditionals and modals must be linked together more closely than has sometimes been recognized, and a unified strict semantics for conditionals and modals is the only way to fully achieve this.

本文提请注意一组反事实条件之间的语言互动，一方面，和可能性情态动词一样可以拥有和可能有， 在另一。这些数据对反事实条件的流行可变严格语义提出了挑战。相反，它们支持严格条件语义的一种版本，其中反事实和可能性模态共享一个统一的量化域。我将争辩说，对这一证据的实用解释不适用于变量分析。并提出对统一严格分析的反例，经过仔细检查，实际上是支持的。最终，条件和模态的语义必须比有时人们所认识到的更紧密地链接在一起，并且条件和模态的统一严格语义是完全实现此目的的唯一方法。
