ABSTRACT This paper engages in a discussion about a select few of the crucial questions raised by Jon Elster's paper on Enthusiasm and Anger in History. It focusses on enthusiasm and engages in particular with Elster's questions and arguments about whether enthusiasm is an emotion or not. In doing so, I am led to ask some general questions about current theories of emotions in the discipline of psychology and their relationship to common sense psychological notions of emotional types. I argue (...) that we need common sense psychological notions in historical explanations, as shown by Elster's examples, and suggest ways of handling a possible mismatch between common sense psychology and more theoretical approaches in psychology that develop somewhat different classifications of emotions and emotional types. The problem of whether enthusiasm really is an emotion can in this way be dissolved, and we are free to explain the historical events employing the common-sense notions as Elster indeed does. (shrink)
