ABSTRACT Fine examination of our accumulated cultural knowledge is especially helpful in studying the emotions, which are only tangentially accessible to experimental manipulation. Here I use the six properties of emotions that Elster has summarized to suggest how they show a need for changes in the science of motivation. The apparent adaptive purpose of emotions lies in their action tendencies – what they add to the cold calculation of advantage. Subjectively they stand out by their intrusiveness, the duration of which (...) often has a half-life. Emotions each have a valence, which suggests that they are not only motivating but also motivated, an implication that requires re-examination of how negativity works. Emotions are also experienced as ‘triggered’, but are so malleable that triggering cannot mean a simple conditioned reflexiveness. Emotions are not only triggered – or motivated – by beliefs, but motivate beliefs in turn, and can be fed back on themselves in a ‘wildfire’ phenomenon. These feedback effects are further evidence against emotions being reflexive. With regard to the three great revolutions, I argue that enthusiasm differs from romantic love only in its object, and urgency comes from the dysphoria of using response suppression for self-control. I can add nothing further to Elster’s masterful history. (shrink)
