Abstract

In the last dozen years or so, our understanding of modality has been much improved by means of possible-world semantics: the project of analyzing modal language by systematically specifying the conditions under which a modal sentence is true at a possible world. I hope to do the same for counterfactual conditionals. I write A□→C for the counterfactual conditional with antecedent A and consequent C. It may be read as ‘If it were the case that A, then it would be the case that C’or some more idiomatic paraphrase thereof.
