The term All Tomorrows has become a touchstone in modern speculative fiction, representing a deep dive into the possible futures of humanity, often tinged with cosmic horror and evolutionary wonder. Originally popularized by C.M. Kosemen's seminal work, it has spawned a fascinating ecosystem of related books, art, and media that explore similar themes of transformation, dread, and the unknown. This exploration goes beyond a single story, connecting dots across genres from paleontology to cyberpunk.
The Core of the Vision: Speculative Biology and Evolution
At the heart of this concept is the book All Tomorrows: The Myriad Species and Mixed Fortunes of Man. This work is a masterclass in speculative evolution, charting a billion-year future where humanity is remade into bizarre and often terrifying forms by alien overlords. It's a narrative that blends hard science with profound horror, asking unsettling questions about identity, agency, and the fragility of the human form. The success of this vision lies in its detailed, biological plausibility, making the horrors feel eerily possible.
This approach to "what if" is mirrored in its paleontological counterpart, All Yesterdays: Unique and Speculative Views of Dinosaurs and Other Prehistoric Animals. While one looks forward, the other looks back, challenging rigid reconstructions of dinosaurs by imagining them with flesh, fat, and behaviors never captured in fossils. Together, they form twin pillars of speculative biology, encouraging readers to think creatively about life in deep time, past and future. For a deeper comparison, the blog post All Yesterdays vs. All Tomorrows: Speculative Biology's Twin Masterpieces offers excellent analysis.
Branches into Cosmic and Existential Horror
The existential dread inherent in All Tomorrows finds a natural ally in the works of H.P. Lovecraft. The themes of insignificant humanity facing uncaring, universe-spanning forces are powerfully resonant. This connection is made explicit in adaptations like H.P. Lovecraft's The Call of Cthulhu (Manga), which visualizes cosmic horror in a gripping graphic format. The fusion of these ideas is explored in articles such as All Tomorrows & Lovecraftian Horror: Exploring Cosmic Dread in Manga.
This vein of horror continues in novels like All the Fiends of Hell, a work of apocalyptic fiction that delves into visceral, end-of-the-world terror. Meanwhile, the visual language of biomechanical nightmare is defined by the iconic artist HR Giger. The HR Giger. 45th Ed. art book is an essential companion for any fan of the aesthetic that influences much of this cosmic horror and evolutionary horror. The blog All Tomorrows & HR Giger: A Guide to Sci-Fi's Evolutionary & Biomechanical Nightmares beautifully connects these dots.
From Page to Game: Interactive Horror
The concepts of All Tomorrows have even crossed into the realm of tabletop role-playing games. The supplement All Flesh Must be Eaten: All Tomorrows Zombies (EDN8015) for the All Flesh Must Be Eaten RPG system allows players to experience a zombie apocalypse scenario infused with the speculative evolutionary twists of Kosemen's universe. It's a perfect example of how a compelling speculative framework can enrich game narratives, offering Game Masters a toolkit for unprecedented horror RPG scenarios. A detailed review can be found in All Tomorrows Zombies: A Sci-Fi Horror RPG Supplement Review & Guide.
Literary and Cultural Echoes
The phrase "All Tomorrows" echoes in other literary spheres, often with entirely different but thematically linked meanings. William Gibson's cyberpunk classic All Tomorrow's Parties (Bridge Trilogy Book 3) uses it to title a novel about the convergence of technology, media, and human consciousness at the end of an era—a different kind of speculative future. For fans of cyberpunk and Gibson's work, the blog All Tomorrow's Parties: William Gibson's Bridge Trilogy Finale Explained provides crucial context.
In music, All Tomorrow's Parties: The Velvet Underground Story captures the spirit of the 1960s counterculture and avant-garde rock that forever changed music history. Meanwhile, works like All the Tomorrows After and All Yesterday’s Papers (All Tomorrow’s Photos Book 2) apply the contemplative, forward-and-backward gaze to intimate human stories of family, memory, and emotion, showcasing the phrase's versatility in literary fiction.
In conclusion, the world of All Tomorrows is far more than a single book. It is a conceptual nexus connecting speculative biology, cosmic horror, iconic art, interactive gaming, and profound literature. Each related work, from the paleoart book All Yesterdays to the dystopian fiction of Gibson, adds a new layer to our understanding of possible futures and forgotten pasts. Whether you're drawn to the biological nightmares, the existential dread, or the cultural history, this interconnected universe offers a rich and endlessly fascinating journey for any curious mind.
