Prompted by what is seen as a missing analysis in the discussions about passion and affect in education, this essay attempts to clarify and provide a context for understanding the contribution of Foucault in the discourse of passion. In particular, the author traces the politics of passion in Foucault's work. A "politics of passion" is the analysis that challenges the cultural and historical emotional rules with respect to what passion is, how it is expressed, who gets to express it and under what circumstances. It is argued that a discussion of Foucault's ideas on passion provides a way of sharpening and clarifying his politics on affect, particularly what is relevant to individual and collective emotional control in education.
