Full Cycle

Story, first published: Science Fiction Stories, Nov. 1955

The people have deserted the cities, returned to a nomadic form of life, and civilization has gone "full cycle," tribe to city and city back to tribe. Psi powers, repressed and ignored in the triumph of machines, are developed as a substitute. An old man, a historian whose occupation is now obsolete, finds a new mission in teaching the tribes about their emerging abilities.
