 If Kolodny is right that there are no pure formal coherence requirements like  (NC),  how are we to explain our intuitions? Kolodny’s strategy is to devise an error theory, thereby seeking to show how coherence (or near enough coherence) in the relevant sense emerges as a by-product of our compliance with other norms, norms that are not themselves pure formal coherence requirements, thus obviating the need for postulating pure formal coherence requirements.
