This Element adopts a naturalistic, cognitive perspective to understand divination.Following an overview of divination and the historical background of its scholarly study, Section 2 examines various definitions and proposes a working definition that balances common usage with theoretical coherence.Section 3 surveys existing theories of divination, including symbolic and functional perspectives, while critiquing their limitations.Section 4 argues for the primacy of cognition in divinatory practices, emphasizing the role of universal cognitive mechanisms and culturally specific worldviews in shaping their plausibility and persistence.Expanding on these ideas, Section 5 investigates the interplay between individual cognition and societal processes, highlighting socio-cultural factors such as the preferential reporting of successful outcomes that bolster divination's perceived efficacy.Finally, Section 6 concludes by summarizing the Element's key arguments and identifying open questions for future research on the cognitive dimension of divination.This title is also available as open access on Cambridge Core.
