The plot, thus outlined, is reasonably straightforward. Its time se
quence has been realigned into linear form here, but as written, the novel is told in various kinds of flashbacks. A pattern of confusion about time results that is appropriate to the theme of the novel and even pleasing, though this may not be why Asimov chose to narrate the novel in that fashion. Contemporary literary critics using theories of structuralism and semiotics, who find themselves concerned about time, among other matters, might find interesting the varieties of time that exist within this novel, which deals with time, discusses time, swears by time ("Time!" and "Father Time!"), and was inspired by
Time.
