This article defines a possible pragmatist approach to the sociology of emotions by discussing and delimiting the concept of “affective rupture.” According to this approach, emotions emerge from the breaking of habits in the face of the transformation of situations, producing reflexivity and relational adjustments. The pragmatist approach problematizes the “rhythm” of emotions, made up of ruptures, moments of quiet, adjustments, harmonizations, restorations, and relational revolutions. Rhythm is what emotions pragmatically “do,” ordering and transforming every social situation. This article employs (...) this idea to reinterpret some sociological approaches to emotions and, in parallel, to show how the interdependence between affectivity and irruption of events that involve and upset is constitutive of everyone's social behaviors.
