The scholarly attention lavished on William James' case study in the "Sick Soul" lecture in The Varieties of Religious Experience of a man disturbed by the vision of an epileptic patient has generally not approached this case as a religious experience. To deepen our understanding of religious experience, I show that this case study can be understood as religious using elements of the theory of religion expounded throughout James' text. I argue that it can be understood as a stage in the process of conversion James lays out. The omission of a subsequent stage highlights James' reasons for rejecting healthy-mindedness as a philosophically adequate perspective and illustrates his claim that the strivings of the conscious mind can stunt the conversion process. Drawing on other philosophical, psychological, and literary texts, I argue that the content of the vision James describes points to solitude as a source of religious disquiet.
