"Dr. Eiseley describes with zest and admiration the giant steps that have led man, in a scant three hundred years, to grasp the nature of his extraordinary past and to substitute a natural world for a world of divine creation and intervention. . . . An irresistible inducement to partake of the almost forgotten excitements of reflection."—New Yorker
