"Dr. Eiseley has written a work of true science which must surely take its place also as great literature."--London Times Literary Supplement

In an unusual blend of scientific knowledge and imaginative vision, Eiseley, anthropologist and naturalist, tells the story of man. He reveals life's endless mysteries in his own experiences, departing from their immediacy into meditations on the long past, wandering--intimate with nature--along the paths and byways of time, and then returning to the present.
