Faultless disagreement
A faultless disagreement is a disagreement when Party A states that P is true, while Party P states that non-P is true, and both parties are not at fault. Disagreements of this kind may arise in areas of evaluative discourse, such as aesthetics, justification of beliefs or moral values, etc. A representative example is John says Mary prettier that Anne, while Bob claims vice versa. Furthermore, in the case of a faultless disagreement, it is possible that if any party gives up their claim, there will be no improvement in the position of any of them.[1]
Within the framework of formal logic it is impossible that both P and not-P are true, and it was attempted to justify faultless disagreements within the framework of relativism of the Truth,[2] Max Kölbel and Sven Rosenkranz present arguments to the point that genuine faultless disagreements are impossible[1][2]
