Counterfactuals and Comparative Possibility

  • David Lewis
Part of the The University of Western Ontario Series in Philosophy of Science book series (WONS, volume 15)


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.
