the tourist who forgets to finish his drink
Schacht ingests the occasional chemical that way grownups who sometimes forget to finish their cocktails drink liquor: to make a tense but fundamentally OK interior life interestingly different but no more, no element of relief; a kind of tourism
Context
The book's control-case for the whole theme, drawn in one man: Schacht uses "to make a tense but fundamentally OK interior life interestingly different" — no relief sought because none is needed, "a kind of tourism" that can forget to finish itself. Set beside Pemulis's precautions and Hal's Pump Room, the tourist who doesn't need much is exactly the negative space that defines the cage the others are in.
