"Measure for a Loner" by Jim Harmon is a science fiction novella written during the mid-20th century. The narrative explores the psychological implications of loneliness in the context of space travel, particularly the necessity for a pilot who can withstand isolation in deep space. The story examines how contemporary society influences perceptions of loneliness and how finding a suitable astronaut amidst a well-conditioned populace proves to be a significant challenge. The plot centers around Dr. Thorn, a historical psychologist who is tasked with identifying a suitable candidate for piloting a groundbreaking interstellar spaceship, the "Evening Star." The government seeks a man who embodies true loneliness, one who can handle the solitude of space travel for extended periods. Thorn discovers two candidates: Gordon Meyverik, who has deliberately isolated himself on Seal Island to prepare for the mission, and Stan Johnson, who enjoys solitude for its own sake. As Thorn assesses their suitability, he grapples with the moral complexities of his task, culminating in a harrowing realization that both candidates may be unable to return from their mission due to governmental manipulation. Ultimately, the novella poses profound questions about loneliness and the human condition in an era where emotional suppression may come at a great cost. (This is an automatically generated summary.)
