Edition details
Book Summary
H. G. Wells envisions a future where the discovery of atomic energy transforms human civilization, leading first to a catastrophic world war and then to a unified World Republic. The novel explores humanity's moral evolution, the obsolescence of nationalism, and the promise of a peaceful, scientifically guided global society.
The book opens with a prelude describing humanity's slow progress from primitive origins to the brink of a new atomic age. Scientist Holsten discovers how to release atomic energy, leading to the development of powerful engines. This technology fuels a devastating global war that destroys old nations and social structures. In the aftermath, a World Republic is established, ushering in an era of peace, economic redistribution, and scientific advancement. The second half of the novel follows Marcus Karenin, a key figure in the new order, as he undergoes a risky operation at a Himalayan clinic. Through conversations with visitors, Karenin reflects on the necessity of destruction for renewal, the evolution of gender roles, and the future of humanity—including control over heredity and space exploration. He dies after a successful surgery, but his vision of a liberated, unified human race endures.
