The terror of the infinite can paralyze even those who have mastered the mechanics of the universe. When history becomes a cold, detached spectacle, the only bridge back to humanity is the quiet persistence of love.
In Short
This story follows Moonson, a man from the year 3689, who travels through history within a protective Time Observatory. Despite his technological mastery, he suffers from "Time Fear"—a paralyzing, existential dread triggered by the vastness of the ages he observes. He abandons his crew to seek solace in the past, only to find that even in a primitive, pre-telepathic era, humans are plagued by their own cycles of fear and longing. Ultimately, he discovers that the internal voids caused by time and space require human connection to heal.
The Story
Moonson is a high-achieving scholar in 3689 who, along with his wife Rutella and other companions, uses a sophisticated machine to witness human history. While the machine provides a safe, glass-shielded vantage point for viewing the past, Moonson suddenly finds himself gripped by a suffocating, irrational terror. The dates and events he once studied with clinical detachment—the Black Plague, the Spanish Armada—now seem like encroaching nightmares. Overwhelmed, he decides to defect. He secretly manipulates the machine’s controls to isolate himself, eventually leaping from the vessel into a verdant field in a past era, leaving his life and his wife behind to escape his internal torment.
He lands in a rustic, pre-technological setting where he is an outsider, unable to speak the local language but capable of reading the telepathic resonance of the people around him. He encounters a young, terrified couple entangled in a dangerous conflict with a local strongman named Mike Galante. Observing their raw, human courage in the face of mortal fear, Moonson begins to find his own strength. He later wanders into a cabin and encounters a struggling, alcoholic writer. Through a silent, empathetic connection, Moonson offers the man a sense of peace that allows the writer to reclaim his creative spark. The writer identifies his visitor as an inspiration, inscribing a copy of This Side of Paradise for him before Moonson departs.
Just as Moonson resigns himself to a lonely, permanent exile in the past, the Time Observatory returns. Rutella emerges, having used the Bureau of Emotional Adjustment to track his psychological signature across the ages. She explains that his "Time Fear" is a natural response to the isolation of the unknown—much like the "Space Fear" experienced by the first explorers of the cosmos. She validates his sensitivity, arguing that his capacity for terror is the flip side of his capacity for imagination. By accepting that he cannot conquer his fear in isolation, Moonson reconciles with his wife. The story concludes with him boarding the ship, finally armed with the self-knowledge that love and trust are the only tools capable of rendering the vastness of eternity endurable.
How It Unfolds
The onset of paralysis Moonson begins his journey as a confident scholar, but the detachment afforded by his machine suddenly gives way to an overwhelming, visceral dread. He becomes unable to process time as a series of events, seeing it instead as a source of inescapable, phantom-like terror.
The decision to flee Driven by an urgent need to escape his internal nightmare, Moonson meticulously plots his departure from the observatory. He successfully severs his connection to his companions and leaps into the unknown, choosing the risks of the past over the suffocating safety of his current life.
The test of empathy In the unfamiliar past, Moonson observes a couple trapped in a cycle of fear caused by a local tyrant. By witnessing their willingness to defy death for the sake of love, he begins to see that human bravery exists independently of technological advancement.
The healing encounter Moonson meets a desperate writer whose spirit has been broken by the fear of losing his relevance and his loved ones. Through a profound, silent exchange, Moonson restores the man's confidence, providing the emotional anchor he previously lacked himself.
The final reconciliation Rutella arrives to retrieve her husband, revealing that his departure was analyzed and understood by his peers. She offers him the insight that his fear is a byproduct of his humanity, leading him to choose connection over the cold isolation of his flight.
The People
Moonson is a man of the future, a scholar whose intellectual brilliance is matched by a fragile, imaginative interior life. He starts the story as a man fleeing his own consciousness, but he ends it as one who acknowledges that vulnerability is a bridge to others rather than a defect.
Rutella is Moonson’s wife, whose groundedness and scientific training provide the means to recover him. She is the catalyst for his return, serving as the voice of reason that reframes his suffering not as a failure of character, but as an inevitable response to the magnitude of the human experience.
The Writer is a historical figure—clearly modeled after F. Scott Fitzgerald—who represents the intersection of artistic genius and paralyzing despair. He is a mirror for Moonson; his encounter with the traveler allows him to overcome his creative block through the simple, steady presence of someone who understands the weight of being alive.
In Its Own Voice
"I am like a child shut up alone in the dark, hearing rats scurrying in a closet thick with cobwebs and the tapping of a blind man's cane on a deserted street at midnight."
Moonson describes the onset of his paralyzing dread as he watches history unfold from his protective time machine.
"There were a few people like that in the world but you sometimes went a lifetime without meeting one."
The writer reflects on the profound impact of Moonson’s silent, reassuring presence during a moment of deep, personal crisis.
"When guided by the sure hand of love and complete trust, self-knowledge could be a shining weapon."
Moonson arrives at this final realization after his wife rescues him, proving that his fear can be managed through connection.
What It's Really About
The story explores the intersection of human sensitivity and cosmic scale. It argues that progress—whether in time travel or technology—cannot solve the fundamental, internal conditions of the human heart. The core tension is between the desire to stand apart from the world as a detached observer and the necessity of being fully "human" within it. By framing "Time Fear" as a successor to "Space Fear," the narrative suggests that as humans expand their horizons, their capacity for dread grows in equal measure. Ultimately, it posits that emotional vulnerability is not a weakness to be purged, but the very quality that makes life meaningful and, eventually, reconcilable.
Why Read It Today
Readers who enjoy mid-century science fiction will find this a fascinating, if occasionally idiosyncratic, piece of work. Its strength lies in its atmospheric prose and its surprisingly tender psychological focus, which elevates it above typical "gadget-heavy" time travel tales. The story feels like a bridge between the hard science fiction of the era and a more introspective, character-driven style.
You may find the period language—specifically the 1950s slang and the somewhat romanticized view of "primitive" life—to be a bit dated. The dialogue can occasionally feel forced, as it aims to contrast the "advanced" future with the "vibrant" past. However, the emotional core remains resonant. The depiction of a person struggling with existential anxiety—a state many modern readers will find relatable—is handled with a surprising amount of warmth. If you are interested in how a writer from the mid-20th century conceptualized the loneliness of the future, you will likely find the journey worth taking. It lingers in the mind not for its mechanics, but for its gentle insistence that even when we are lost in the vast, cold sweep of eternity, we are never truly beyond the reach of human empathy.
