Trollope's novella is as timely as ever in light of our current partisan politics and confrontation with fanatical ideas.
As it is readily apparent to any Trollope reader that his one foray into the science fiction genre is surprisingly uncharacteristic, the dynamic needn't be over emphasized, as it is probably more interesting to note how the novella is very much in line with his writing in general.
The choice of first person is actually as much of a departure as anything. Failing to recall encountering Trollope doing so anywhere else, a Google search on the topic only brought up his autobiography and this novella "The Fixed Period".
Now, Trollope's third person is a god-like, omniscient chronicler, one who knows the inner lives of every single character better than they do themselves which generally creates the peculiarly Trollopian dynamic of characters meeting each other in context, with the reader knowing everything about them with the effect often being comic in proportion to what they misunderstand about each other.
The first person narrator of "The Fixed Period" is the President. Neverbend of the fictional colony Britannula and in terms of his personal empathy and reading of other characters, he does pick up the slack for Trollope's take you along by the hand guide, as he does seem trustworthy, empathetic and accurate in his observations regarding the other characters but there a muting, if not a total loss, of that comedy of errors whereby people misconstrue each other.
This is a very late work for Trollope and the question of what he gains by dropping his all seeing third person with all of its comic and dramatic potential should be asked. For one thing, it should be noted that in his usual mode, he often grants the reader the benefit of his personal opinion and wisdom regarding his characters and his style when doing so is often pre-Brechtian in that he will insert his thoughts with references and reminders of the story being a story written by an author and intended for an audience.
With "The Fixed Period" Trollope is dealing with a passionate fanatic, President. Neverbend, who believes in the notion of creating prosperity for all mankind by depositing people past the age of 67 1/2 into a kind of sanctuary where they will live for a year before being put to death via opened wrists in a bath while taking opium. He is a founder of his nation which included no old people so that they were able to agree to this idea before its terrors were near enough to sufficiently impress. As the tale starts, his friend, Gabriel Crasweller, a man of unusual good health and activity, who had long ago agreed to be the first such deposited, is coming upon his time, he has a lovely daughter much attached to him, and the president's own son is in love with her. With other citizens concerned in that they would be next in line, and as we learn, the President's own wife against him, he spends much of the book in opposition against seemingly everyone in his colony and, then later, sailors sent from Great Britain to stop the idea from being carried out.
So one benefit of Trollope dropping the third person is that Trollope's own interloping, or judgments, on his characters or work would have been redundant given that the practical, pragmatic, and altogether human reaction of the stories world to its first person narrator and his idea for mankind likely matches Trollope's own reaction precisely.
President. Neverbend's tale is in the form of his own book, telling his own story as something he will leave for future generations so the first person works naturally within this framework and I believe the comedy and social commentary normally derived from Trollope's third person, is transferred to the reader's own reaction to this first person single object, and that they are meant to be guided in their reaction both by plain common sense and the reactions of the book's other characters. His frequent comparisons of himself with Columbus and Galileo are ironic in that those men believed in something that turned out to be true whereas Neverbend believes in something no one agrees with.
One possible sibling in Trollope's work for Neverbend can be found in his novel, "He Knew He Was Right", one his more popular works that he nevertheless considered a failure. He felt his book had been undermined by the main character being unsympathetic and by the main plot evincing less interest than the subplots and secondary characters. The main characters of each book are similar in that they are passionately married to an idea or notion with whom no one else can agree, including the reader. The choice of first person is perhaps used to turn a scheme Trollope thought he had failed with into a success.
With, "The Fixed Period" Trollope's President Neverbend gets to thoroughly explain himself and is convinced of the rectitude of his ideas and the benefits that would accrue to all of his mankind if they were to come to fruition. His ideas though, that of depositing and then ending the lives of elder people, while proving to be unsympathetic to his own colony and the world at large, and the readers of the book too, unlike the main character of "He Knew He Was Right", do not lead to a corresponding lack of feeling for the man himself.
Trollope's great achievement with "The Fixed Period" therefore, beyond the originality of its science fiction which would influence many later works in various mediums like, "Logan's Run", largely can be found in how he successfully presents a fanatical character, whose ideas the reader and no one else can agree with, who is nevertheless so good, genial and benevolent that he is wholly forgiven, again by both the world of the book and the reader, and remains sympathetic. One wonders if this could be achieved via a first person narrative of any fanatical member of any dogmatic party with wrongheaded ideas.
Finally, the book rhymes with the majority of Trollope in that the plot does not fail to concern itself with the settling of young people's romance and their property. It is unusual though in that the usual happy ending, union through marriage of the young people, is not the book's final point and is merely implied prior to the final section as President Neverbend sails for England and can't be present.
Instead, "The Fixed Period" ends with him aboard the ship complaining piteously of his life and future prospects to a lieutenant who he has recently met, befriended and communicated his ideas. Though it be his life's mission to promote his grand idea, he asks the lieutenant whether anyone will even believe that he believes in his own idea and the lieutenant, though in disagreement as to the idea, acknowledges his belief that Neverbend is in earnest. Curiously, this is seemingly no comfort to Neverbend as he qualifies the lieutenant's statement, restates his pity of himself and the book ends but the exchange should be a comfort to the reader. The ending is emblematic of a book that is a master class in showing how people can remain civilized and sympathetic with each other in the face of extreme disagreement. Neverbend might not realize it but the book has subsumed and incorporated his unique existence and ideas into the world at large which has found acceptance and a place for him. This is all regenerative for the reader, validating of civilization itself, and stamps the novella as high comedy.
