It was to write a historical novel of the future; to tell the story of the fall of the Galactic Empire. My enthusiasm must have been catching, for Campbell grew as excited as I was. He didn't want me to write a single story. He wanted a series of stories, in which the full history of the thousand years of turmoil between the fall of the First Galactic Empire and the rise of the Second Galactic Empire was to be outlined. It would all be illuminated by the science of “psychohistory” that Campbell and I thrashed out between us.
