 As noted in  section 7.1,  emotions are often recalcitrant to reason: many people do not believe that flying is dangerous, and yet continue to fear it. But emotions manifest rationality as coherence in a great many cases. This is due in part to the fact that emotions have cognitive bases, which consist of cognitions whose function is to provide emotions with their particular objects—I must believe, perceive or imagine being on an airplane prior to fearing it.
