Indicative and Subjunctive Conditionals in Commitment Space

Abstract

The paper argues for a treatment of conditional sentences as conditional speech acts. It provides a formal implementation in the framework of commitment spaces, arguing that this approach has advantages over the conditional proposition account, as it motivates the known restrictions for embedded conditionals. It also introduces an extended model of commitment spaces for subjunctive conditionals, it shows how they affect revisionary updates, and it indicates ways to deal with the problem for the propositional account pointed out by Alonso-Ovalle and Tichý.
