Tony Tanner considered the novel an exploration of the plots individuals ascribe onto the ambivalent universe they have no choice but to confront, during a 20th-century period in which genuine communication between individuals has been eroded and in which ambiguous societal forces are at work (intentionally or inadvertently) towards a state of entropy; "SHROUD asks, 'Has it occurred to you there may be no more standards for crazy or sane, now that it's started?' And Benny answers, 'What, for Christ's sake?' What the 'it' is that has started (if there is an 'it'), what common process links remote imperialist incidents with contemporary automation, tourism, Hitler, and the Whole Sick Crew (if there is any linking common process)—this is what the whole book is about."
