Flight Through Tomorrow
Stanton A. (Stanton Arthur) Coblentz (1896–1982)
The chemist narrator discovers a drug that shatters the boundaries of time, projecting his consciousness forward to witness the horrific twilight of human civilization and the strange, luminous salvation that follows.
In Short
This science fiction narrative chronicles a daring psychological experiment gone awry. After ingesting a compound that separates his mind from his body, the narrator observes a harrowing future where humanity has decimated itself through mechanized warfare. As he drifts across a broken, depopulated Earth, he witnesses the tragic decline of survivors unable to sustain a high-tech society without their lost infrastructure. Ultimately, the story transcends its bleak premise, offering a meditative conclusion on the potential for human preservation through the arrival of mysterious, transcendent beings from the stars.
The Story
The narrator, a chemist, succeeds in synthesizing "Relin," a drug intended to release the psychic entity from the physical body. Upon taking a dose, he experiences a sudden, vivid displacement from his modest room into a future landscape defined by devastation. High in the sky, he sees comet-like projectiles raining destruction upon a city, leaving behind only vast craters and mountains of scorched rubble. His consciousness floats over this "shattered" world, confirming that the catastrophe was a product of total, super-scientific war.
Searching for signs of life, he descends into subterranean caverns where he finds huddled groups of survivors. These people, though modern in appearance, are trapped in a state of hopeless despair, having lost the technicians and power sources necessary to maintain their mechanical civilization. As time passes within his vision, the narrator witnesses the decline of these survivors. Some become feral, roaming the ruins like starved animals, while others perish from famine or internal conflict. He realizes with profound sadness that mankind, having evolved to depend entirely on complex machines, lacks the capacity to return to a primitive, self-sufficient state.
Eventually, the narrative shifts to a remote island, a final refuge for the last dozen humans on Earth. Unlike the haggard refugees of the caves, these individuals possess a noble, serene quality. Their survival is not a struggle for existence, but a waiting period. A radiant, god-like being descends from the stars in an illuminated sphere, offering these few remnants of humanity a chance to be transplanted to another planet. This visitor explains that while human evil necessitated the destruction of the old world, the inherent goodness of the race has earned them a new beginning among the stars. The survivors board the vessel, and as it departs, the Earth is left entirely empty of human life. The narrator is suddenly jolted back to his own time, finding that only a single minute has passed in the physical world, leaving him with an unshakable conviction in the reality of his vision.
How It Unfolds
The experiment begins The narrator explains his obsession with the "Release Drug" and the potential for the mind to traverse space and time. He initiates the process in his apartment, fully aware of the risk of death or madness, and experiences a physical snapping sensation that triggers his journey.
The desolation of the future Arriving in a post-cataclysmic world, the narrator observes the final moments of a civilization destroyed by automated, long-range aerial bombardment. He wanders over ruined cities and poisoned fields, realizing that the infrastructure of human existence has been irrevocably pulverized.
The decline of the survivors The narrator finds a desperate remnant of humanity living in caves, unable to feed themselves or repair their machines. He documents their slow, agonizing transition from modern citizens to starving, savage bands, concluding that modern man cannot survive the loss of his technological crutch.
The final deliverance Moving further ahead in time, the narrator witnesses the very last humans on Earth, who possess a peaceful, enlightened nature. A celestial being arrives to transport these survivors to a new world, effectively ending the human experiment on Earth while preserving the best of the species.
The People
The narrator serves as the primary lens for the story. As a scientist, he is driven by a cold, intellectual desire for knowledge, which he prioritizes over his own safety. Throughout his journey, he moves from the detached observer of a tragedy to a witness who feels a deep, empathetic connection to the suffering he observes. By the end, he is transformed from a skeptic of the soul into a man who possesses a profound, existential sense of peace.
The survivors of the future are defined by their environment. Initially, they are "caved-dwellers"—haggard, broken people who have lost their identity along with their machines. They are trapped by their own history, unable to adapt to a world that no longer requires their complex, mechanical skills. Their descent into feral behavior represents the tragic failure of a race that has outpaced its own ability to survive.
In contrast, the final few survivors on the island are the "perfect specimens." They possess broad, noble brows and a calm, musical quality in their smiles. They are the antithesis of the scavengers, representing the successful distillation of human potential. They do not resist their fate but embrace the arrival of the "radiant one," a superior, star-faring entity who serves as a judge and guardian. This figure acts as a bridge between the ruined past and a speculative future, embodying the "good" that the narrator insists can never be entirely expunged from the human spirit.
In Its Own Voice
"I shudder and gasp and marvel even as I tell of it--is that I did obtain a minute quantity of a drug which, by putting the body virtually in a state of suspended animation, could release the mind to travel almost at will across time and space."
The narrator describes the terrifying moment he realized he had invented a mechanism for temporal travel.
"I knew that their fight was not merely a bitter one--it was hopeless."
The narrator observes the pitiful condition of the first group of survivors to emerge from the subterranean caves into the wasteland.
"Through the immense evil within the breasts of your kind, you have been purged and all but annihilated; but the good within your race has also been mighty, and can never be expunged."
A star-faring visitor explains the purpose of the final rescue to the last humans on Earth.
What It's Really About
The book is a dark contemplation on the fragility of civilization and the dangers of technological over-dependence. It argues that modern humanity has fundamentally altered its nature by offloading survival to machines; when those machines fail, the human capacity for basic existence is lost. Beneath the plot, there is a recurring question about the "psychic entity"—the idea that the spirit is a distinct, durable force that can survive the death of the body and the collapse of the material world. The narrative suggests a cyclical view of history, where total destruction is not an end, but a violent purge. It posits that while humanity may fail through its own "immense evil," there is an enduring, inherent "good" that justifies its eventual restoration.
Why Read It Today
Readers who appreciate mid-century speculative fiction will find this a fascinating, if brief, meditation on the anxieties of the nuclear age. The writing is marked by a certain Victorian-era earnestness and a grand, sweeping tone that prioritizes philosophical stakes over gritty realism. It is a quick read, but one that feels heavy with the weight of the author’s concerns regarding war and the loss of human agency.
You should be prepared for the period's dramatic, slightly formal prose, which reflects the science fiction conventions of its time. The narrator’s voice is that of an educated, detached observer, which adds a sense of clinical distance to the horrific scenes he describes. Some readers may find the sudden, deus-ex-machina ending to be a departure from the bleak, realistic tone of the first half, but it serves as an essential thematic resolution to the author’s argument about the persistence of the human spirit. It is a story that feels like a classic cautionary tale, lingering in the mind as a reminder of the precariousness of our progress. It is best suited for those who enjoy stories that use the framework of a journey to explore the "big picture" of humanity’s survival, rather than those looking for a character-driven or action-heavy plot.
