Kurt Vonnegut's Mother Night is a novel and postmodernism is a literary and philosophical theory. Although it is possible to use postmodernist literary theory to analyse Mother Night, and also find notions about ethics congruent with postmodernist theory articulated by the narrator of Mother Night, to treat a novel as a theoretical treatise is to make a category mistake. One can argue, however, that the protagonist, like that of the Victorian sensation novel and of modernist works like "Prufrock" is strongly shaped by external forces. One could argue that if one reads Facebook as a text, it to shows the individual not as agent but as a constructed identity.
