Merlin Donald
Canadian cognitive neuroscientist (b. 1939) whose three-stage theory of cognitive evolution — <em>mimetic</em>, <em>mythic</em>, <em>theoretic</em> — provides the architectural framework for understanding AI as a fourth transition.
Merlin Donald is a Canadian cognitive neuroscientist and evolutionary psychologist whose groundbreaking work has fundamentally reshaped our understanding of human cognitive evolution. Born in Nova Scotia and educated at McGill University and Yale, Donald spent much of his career at Queen's University in Ontario, where he developed his influential three-stage theory of cognitive evolution. His seminal work Origins of the Modern Mind (1991) proposed that human cognition evolved through three major transitions: from episodic memory (shared with other primates) to mimetic culture (bodily imitation and gesture), to mythic culture (oral narrative and language), and finally to theoretic culture (external symbolic storage through writing, mathematics, and formal systems). Donald's theory differs from purely biological accounts of human evolution by emphasizing the role of cultural and technological innovations in shaping cognition itself.
