Verne was a universal teacher, both of youth and age. From him the whole world garnered knowledge without effort; for all listened with pleasure while he spun his tales. He was a supreme master of imagination, and without imagination man is nothing; for all greatness is but a phase of imagination. It is the creative force of the world. Under Verne's guidance his readers travel in every land, examine every mode of life and labor, view all the strangest wonders of the universe.
