How can tolerate not be considered a propositional attitude? That is the question that has plagued me the last few days. This follows a graduate workshop in which another student put forth the argument. The reason provided was that "to tolerate" is not directed at the proposition like "to believe" since sometimes one is not tolerating the proposition but another object (e.g., oneself). So, it is a semi-propositional attitude. I am not satisfied with this idea. For, fear could be viewed the same way. Has anyone else heard this argument expressed? If so, can you clarify the grounds on which it is made? Or, can we just dismiss it?
