Over the course of Kurt Vonnegut's career, unorthodox management of time became one of the many hallmarks of his works of fiction (Allen 37). Although The Sirens of Titan (1959) is only his second novel, this mark is still prevalent. When looking at science fiction, it's often helpful to incorporate ideas from other works in the genre. This concept is exemplified by the "megatext," an aspect of science fiction that involves the application of the reader's own knowledge of the genre to a new encounter (Evans xiii). Working within the megatext, Ursula K. Le Guin's The Dispossessed (1974) offers an interesting avenue for exploring time management and its consequences in Vonnegut's The Sirens of Titan. This argument will be constructed, first, with an overview of the plot of Sirens. , which is particularly necessary given its sprawling nature. Following this overview, the connection between The Dispossessed and The Sirens will be exposed regarding time management in each novel. This primarily involves a discussion of the sequential and simultaneous time perspectives detailed in The Dispossessed and their application to mermaids. Where the two works diverge is in the reconciliation between these two perspectives. In The Dispossessed, reconciliation is more a matter of mathematics and theory. In Sirens, the character of Winston Niles Rumfoord constitutes a more tangible manifestation of the relationship between sequence and simultaneity. How Rumfoord reconciles these two perspectives will be explored through his founding of the Church of God the All-Indifferent, his existential attitudes, and the parallels that can be drawn with other mythologies and traditions. There's a lot going on in The Sire..... . middle of paper......early. When he entered the chrono-synclastic infundibulum, he and his dog Kazak were converted into wave phenomena, resulting in an existence that spanned both space and time. Essentially, he was forced to adopt a simultaneous perspective. What makes Rumfoord's case particularly compelling is that he is capable of materializing and interacting with other beings. These beings do not share his simultaneous vision. In order to communicate coherently with them, he must adapt his knowledge and experience to a sequential mindset or a “one-off way of speaking” as Rumfoord calls it (20). Interestingly, Rumfoord's description of time bears a striking resemblance to the comparison in Shevek's books. It connects the experience of time to roller coasters. He can see the shape, "every dip and every bend", but the cyclist must still, ultimately, go up and around. (54).
