But the prospect that Billy is mentally ill should not compel us to dismiss the events and stories in the novel as the ramblings of a madman. Insanity extends beyond Billy himself, infiltrating the world in which he lives. For instance, Vonnegut appears intermittently as a character, not only in Billy’s war experiences but also on the night of Billy’s abduction by aliens. Billy’s hallucination of the image of Adam and Eve in the boots of his commander does not spring wholly from his brain; earlier, the commander himself invokes Adam and Eve as he holds up his boots to demonstrate their high polish. It becomes clear, then, that characters’ psychologies and mental states overlap in a realm of dementia. It is impossible to ridicule Billy’s thoughts or words as insane ramblings, since his world contains such illogical and unexplainable events. Furthermore, the anonymous narrator, who at times sounds like Vonnegut himself, may be a participant in this frenzy of insanity, blurring the boundaries between reality and fantasy.
