 Extending Stalnaker’s account to conditional commands, “If it rains, take your umbrella” becomes “In the nearest possible world in which it rains, take your umbrella”. Suppose I have forgotten your command or alternatively am inclined to disregard it. However, it doesn’t rain. In the nearest world in which it rains, I don’t take my umbrella. On Stalnaker’s account, I disobeyed you. Similarly for conditional promises: on this analysis I could break my promise to go to the doctor if the pain gets worse, even if the pain gets better. This is wrong: conditional commands and promises are not requirements on my behaviour in other possible worlds.
