# Sirius (novel)

Sirius is a 1944 science fiction novel by the British philosopher and author Olaf Stapledon, whose title character is a dog named Sirius with humanlike intelligence. A sense of existential questioning suffuses the book, as the author delves into aspects of Sirius's psyche. The novel deals with many human issues through Sirius and his experiences, his unusual nature, his ideas and his relationships with humans. The characters go to great lengths to prevent Sirius from becoming a circus-type wonderdog, and instead, they seek to develop Sirius's character much like a family would create and foster that of a human child.

## Plot summary

In early 20th century North Wales, scientist Thomas Trelone embarks to hormonally enhance the cognition and lifespan of sheep-dogs, eventually succeeding in creating a viable puppy, Sirius, just as his daughter Plaxy is born. Sirius soon exceeds Thomas's expectations by achieving human intelligence and learning to talk, albeit with not easily recognizable speech. As such, Thomas and his wife Elizabeth raise Plaxy and Sirius as if they were siblings. Despite their love for each other, Plaxy and Sirius begin to grow apart when she joins a boarding school while he becomes the sheep-dog of Mr. Pugh, an acknowledgement of Thomas. Invested in Sirius's well-being, Thomas keeps his intelligence hidden from Mr. Pugh as well as the public. After a year, Sirius eagerly returns home to meet Plaxy again and discuss with Thomas about finding his place in the world by pursuing personal growth.
Partly to comply with his desires, Thomas decides to take Sirius to the University of Cambridge and reveal him for the first time to his most trusted colleagues, who react with amazement. Sirius's time at Cambridge partly satisfies his mental pursuits, but his well-being, self-control, and fitness decline due to homesickness, pampering, and inactivity. He manages to arrange a meeting with Plaxy, now a university student, but she fails to console him.
Embittered by the encounter, Sirius begins to assess humanity and nature more harshly, flipping between love and hate towards Plaxy and sporadically rejecting his human side by going savage. Yearning for something more wholesome than science, Sirius experiences a spiritual epiphany and becomes interested in religion. However, when Elizabeth arranges a meeting with Reverend Geoffrey Adams, he is disappointed to learn that human religion centers more on doctrine and mythology than love or spiritual truth. Nevertheless, after great persuasion to express himself, Geoffrey, with caution, allows Sirius to sing in his church in front of an astounded audience, becoming a local phenomenon.
Sirius returns home and resumes his occupation as a sheep-dog, just as World War II hits Britain. Geoffrey is killed and Sirius witnesses Thomas being crushed to death during a bombing, with Elizabeth succumbing shortly after to shock from believing to have lost his son in battle. With his masters and parental figures dead, Sirius begins working with Plaxy at a farm, aided by the Pughs. Though the Pughs are now aware of Sirius's true nature and welcome it, the townspeople largely see him as an abomination and fabricate rumors of bestiality with Plaxy. The story's narrator, who is also Plaxy's lover, visits them. He confirms that Plaxy and Sirius are indeed very close, and although she accepts him as a lover, her main priority is Sirius. The rumors compel authorities to conscript Plaxy to public service, leaving Sirius alone managing the farm.
Depressed and enraged by the townspeople's hostility, Sirius leaves the farm to live in the wild. After he attacks livestock and kills a couple of farmers in self-defense, the authorities set out to hunt him down. News of the incidents compel Plaxy to return to the farm, planning to rescue Sirius and escape to Scotland. She eventually finds him and manages to reawaken his human mind by consoling him. Despite her efforts, Sirius laments his existence as an irreconcilable fight between his human and canine sides after all. Sirius is shot by a farmer and dies professing his love for Plaxy, stating their time together, despite all the hardship, was worthwhile.
