The bodysnatchers are ultimately defeated through the efforts of indomitable spirits like the protagonist Miles Bennell. The pod-creatures flee when they realize that human beings will fight, even against hopeless odds, rather than surrender their individuality and that distinct quality of human life: the ability to feel passion and care intensely. The novel's most explicit theme is its praise of American self-reliance and hardiness. The same spirit that enabled Americans to survive the Depression and to defeat the Axis powers in World War II overcomes an alien invasion.
