This case study in the history of “passion” and “emotion” is based on the writings of William James. James is famous for his (1884) theory of emotion. However, like his illustrious colleague, Théodule Ribot, he also recognized the importance of “passion” in psychology. That aspect of James’s work is underappreciated. Ribot explicitly defends the necessity of including “passion” in psychology. James does not go that far. But he does utilize a very similar concept in connection with the term “passion” and (...) there can be little doubt he considered it scientifically legitimate. Consequently, like Ribot, James must be considered an exception to historical accounts of this period which describe a transition from “passion” to “emotion” in which “passion” plays no part. (shrink)
