The ancients disputed the use of affect in argumentation in similar terms to the anomalies it presents in psychological case studies. In this chapter, Jung’s ‘A Study in the Process of Individuation’, in which he examines the case of Miss X, comes under scrutiny. Using rhetorical analysis of the strategies of narratio from forensic rhetoric’s canon, that case study focuses in one instance on the mark Jung supposes indicates that a progression is made in the individuation process: spontaneous emotion. This is revealed as a cultural phenomenon, relative to place and time. Further expressions of affect are also subject to interpretation and the contextual perspectives tainting those interpretations are explored.
