What Lewis wants to symbolize through Zenith (and Gopher Prairie from his novel Main Street) is the "[l]ife dehumanized by indifference or enmity to all human values." According to Whipple (1962: 72), this is the key for Zenith, as a "city of the dead," or through a Coleridgean lense (which we believe is a crucially relevant way to look at Zenith)--a Xanadu seen as a Fool's Paradise, whereinto also the author-creator himself may fall if he indulges too much or at all in the ghostly evanescent delights of opium, forgetting that there is also a price to be paid for them: the terrors of opium (see infra).

He uses various metaphors to express his desire for a larger structure on which to hang individual pieces of culture: "a bracket for one kind of ideas, I mean that will hold a whole set of ideas and keep them apart from another set" (29), a "card-index" or "set of cubby holes whereinto one can sort one's values and make them into a schema" (305), or "some sort of provisory scaffold, hat-rack or something to work from" (260).
