Suppositional theories of conditionals take apparent similarities between supposition and conditionals as a starting point, appealing to features of the former to provide an account of the latter. This paper develops a novel form of suppositional theory, one which characterizes the relationship at the level of semantics rather than at the level of speech acts. In the course of doing so, it considers a range of novel data which shed additional light on how conditionals and supposition interact.

条件句的假设理论

条件句的假设理论以假设和条件之间的明显相似性为出发点，利用前者的特点来解释后者。本文发展了一种新形式的假设理论，它在语义层面而不是在言语行为层面刻画了这种关系。在这样做的过程中，它考虑了一系列新数据，这些数据进一步阐明了条件和假设如何相互作用。
