Edition details
Book Summary
A philosophical and scientific exploration of how the world might end, examining fire, flood, drought, cold, and cosmic collisions alongside human fears and prophecies. Geoffrey Dennis weaves together mythology, religion, and astronomy to question whether humanity's end is imminent or distant, certain or unknowable.
The book surveys potential apocalyptic scenarios—comet impacts, global fire, floods, drought, ice ages, and cosmic crashes—each rooted in both ancient myth and modern science. It contrasts the certainty of individual death with the uncertainty of Earth's demise, exploring how cultures have imagined the end through numerology, prophecy, and religious doctrine. Dennis examines the tension between scientific predictions and supernatural beliefs, arguing that both are attempts to grapple with the same unknowable future. He distinguishes between the end of mankind and the end of the planet, considering scenarios where humanity perishes first or outlasts its world. The narrative also delves into philosophical questions: Is the universe eternal? Will entropy lead to heat death? Are we alone in the cosmos? Throughout, the book balances optimism and pessimism, noting that while some see progress and adaptation, others foresee degeneration and collapse. Ultimately, Dennis concludes that the end is inevitable but its timing and manner remain beyond human certainty, leaving readers with a humbling perspective on our place in the universe.

This is the story's dramatic climax because it shifts from the external, physical question of *how* the world…
Jesus Christ
Jesus stands at the center of the book's argument about how prophecy works: whether his foretellings in Matthew were meant as literal catastrophe or as a vision in which a trillion years shrivel to a pinpoint. Dennis traces how the four gospels rarefy the terror from Matthew's physical fear to John's philosophical calm, and how the early Church, reading the time-phrases literally, saw Nero and the fall of Jerusalem as the end already arriving. He matters because every later date-setter, from millennial monks to William Miller, is arguing with him.
William Miller
Miller belongs to the long procession of date-setters Dennis chronicles, the Protestant heirs of a numerological game that passed from the Rabbis and the Sibylline Leaves into eager new hands. His failed prediction is one more entry in the ledger of avoided disasters that shook the Church and then, oddly, left it standing. He matters because his earnest miscalculation shows how the machinery of apocalypse keeps running even after the appointed hour passes without incident.
Doctor Auriol
Cleric who debated the 1524 deluge prophecy with astrologer Stoffler.
Crazy Amos
Local eccentric who spreads doom-laden predictions about the end.
Tsar Alexander
Russian emperor whose reign is tied to apocalyptic speculation.
Henry Howard
English nobleman and poet, referenced in end-times contexts.
Uncertainty of Knowledge
The book repeatedly emphasizes that humanity's understanding of the world's origin, destiny, and fundamental nature is based on guesses, not certain knowledge, contrasting scientific theories with religious and mystical explanations.
Humanity and Mortality
The text draws parallels between individual human death and the eventual death of the Earth, exploring how both are subject to accident, disease, and inevitable decline, with humanity's physical and moral progress debated.
Eschatology and Prophecy
A central theme is the history of predictions about the end of the world, including millennial fears, numerical prophecies, and the contrast between near-term and far-term expectations across different cultures and eras.
Science vs. Religion
The book contrasts scientific explanations for the world's end (cold, drought, comet, fire) with religious and magical beliefs, while also questioning whether science itself is merely a symbolic system with no direct access to reality.
