 Sigmund Freud and other early psychologists aimed to explain religion as the result of cognitive dispositions. For example, Freud (1927) saw religious belief as an illusion, a childlike yearning for a fatherly figure. He also considered “oceanic feeling” (a feeling of limitlessness and of being connected with the world, a concept he derived from the French author Romain Rolland) as one of the origins of religious belief. He thought this feeling was a remnant of an infant’s experience of the self, prior to being weaned off the breast. William James (1902) was interested in the psychological roots and the phenomenology of religious experiences, which he believed were the ultimate source of all institutional religions.
