This paper recommends that we treat these questions as addressing the stability of doxastic commitment in the two dimensions. If we think of belief as paradigmatically the product of doxastic deliberation, as some philosophers now do,1 then we can view forming a belief as bringing doxastic deliberation to a proper conclusion, thereby generating a properly stable commitment. And we can make our questions more specific: Does a doxastic stance that fails to do justice to expected future opinion manifest a properly stable orientation as it moves forward into that future? Does a doxastic stance that fails to do justice to interpersonal disagreement manifest a properly stable orientation as it moves outward into the social give-andtake of reasons?2 How far, if at all, do these species of doxastic stability run in parallel?
