How and why do myths arise?
It is trite to say that one’s pet subject is interdisciplinary. These days what subject isn’t? The prostate? But myth really is interdisciplinary. For there is no study of myth as myth, the way, by contrast, there is said to be the study of literature as literature or of religion as religion. Myth is studied by other disciplines, above all by sociology, anthropology, psychology, politics, philosophy, literature, and religious studies.
