| Abstract |
|---|
We propose a straightforward analysis of counterfactual donkey sentences, by combining the Lewis/Stalnaker analysis of counterfactuals with standard dynamic semantics. The main idea is to define a similarity relation between world-assignment pairs such that two such pairs are unconnected if their assignments differ. We show that with the help of this ordering relation we can also account for a number of related problems involving disjunctions and the use of any in counterfactuals and permission sentences.
