Psychology has generally had a rather stunted view of the mind. In the behaviorist era it essentially denied the existence of mind altogether, and even the cognitive revolution seemed to promote a rigid view of the mind as tied to specific inputs. This began to change when Endel Tulving proposed episodic memory as the conscious replaying of past events-a conception that was later broadened into the more general concept of mental time travel: the ability to travel mentally backward and forward in time, a basic component of imagination. The two books under review, both informed by evolutionary science, illustrate involvement of the humanities in further expanding our understanding of the imagination- the mental capacity that enables us to transcend time and space, voyage into fantasy, and cultivate the creative arts. The historian Felipe Fernández-Armesto goes so far as to suggest that human imagination expanded at the expense of memory, and was even the basis of language. The volume edited by Carroll, Clasen, and Jonsson, all literary scholars, takes us on a wider tour of the fruits of imagination-religion, music, the arts, literature. These books may help place human creativity and imagination in an evolutionary context, and enlarge our understanding of evolution itself. They may also help overcome poststructuralist attitudes that threaten the integrity of the humanities themselves.
