The book contains a brief pre-figuring of Huxley's later novel, Brave New World. Mr. Scogan, one of the characters, describes an "impersonal generation" of the future that will "take the place of Nature's hideous system. In vast state incubators, rows upon rows of gravid bottles will supply the world with the population it requires. The family system will disappear; society, sapped at its very base, will have to find new foundations; and Eros, beautifully and irresponsibly free, will flit like a gay butterfly from flower to flower through a sunlit world."
