Is there any word to describe a situation in which one is undecided about the relative desirability of two mutually exclusive alternatives in an abstract sense? For example, as regards the relative merits of doing X and not doing X, I have always been in a state of ____. As regards which of the two ideologies is more suited to my temperament, I have been in a state of ______.
"vacillation" is one word I thought about. But "vacillation" seems to be rather concrete in the sense that it seems to be more apt for common alternatives such as "My vacillation in regard to wearing a suit on that occasion led to a delay in my departure". Are there other words or phrases or idioms that describe what I have in mind?
