The fact is that there is not one revolution in the study of emotions going on right now, but three, proceeding almost independently of each other. Psychologists have found ways of applying laboratory techniques devised for the study of cognition to questions involving emotion, sparking one revolution. Ethnographers have developed new field techniques and a new theoretical apparatus for understanding the cultural dimension of emotions, sparking a second. Finally, historians and literary critics have discovered that emotions have a kind of history (but what kind is not entirely clear).
