“Utopia retains throughout its long history the basic form of the narrative of a journey. The traveler in space or time is an explorer who happens upon utopia. He (or, more recently, she) meets its people, usually at first its ordinary people, observes them at work and play, sees their dwellings and their cities... The traveler is, as are we, the more prepared to accept the validity and desirability of the general principles for having seen with his own eyes its effects in the daily life of its inhabitants.”
