Most new ideas come to us not through pure logic, but through a fusion of memory and imagination. If new ideas were purely a product of rationality, other people would quickly grasp and embrace novel solutions. People’s lack of imagination prevents them from comprehending the significance of an innovative idea.

There is a tendency even for the most logical and classically educated people steeped in rational scholastic traditions to assume that if any new hypothesis were correct, a scholar would already written it in a book.
