Utopias (5.18), which were a pretty popular trend in the late 19th century. Two important Utopian works that Wells is probably thinking about are (American) Edward Bellamy's Looking Backward (1888), where a Bostonian wakes up in AD 2000 and finds that every class issue has been resolved; and (British) William Morris's News from Nowhere (1890), where the future is better because work has become fun. At 5.40, the Time Traveller complains that he doesn't have a "cicerone," which is a fancy word for guide, because in these Utopian works, the stranger is usually led around by a native who explains everything very clearly.
