The Earliest Sci-Fi Novel is also a Work of Philosophy

Margaret Cavendish’s 1666 novel *The Blazing World* is presented as far more than early science fiction: it functions as a vehicle for her metaphysical philosophy, her critique of contemporary knowledge, and a bid for authorship and intellectual authority in a world that largely excluded women. The central payoff is that Cavendish’s fictional universe—populated by animal-people, built around a “paradise” social order, and structured as a series of philosophical investigations—mirrors her core claim that reality is fundamentally material, including minds and cognition. That matters because it reframes a canonical “first sci-fi” label into a sustained philosophical program, showing how speculative storytelling can carry rigorous ideas rather than merely entertain.

The discussion begins with Cavendish’s historical position and the obstacles that shaped her reception. Born Margaret Lucas, she became a maid of honor to Queen Henrietta Marie, later followed the queen into exile in France, and married William Cavendish, who supported her writing and helped publish her works. Despite producing full-length books under her own name—rare for women at the time—her readership remained limited, and some critics even tried to credit William as the “mind” behind her thinking. The conversation treats that neglect as both a personal injustice and a structural one: philosophy depends on dialogue and recognition, and Cavendish’s exclusion meant she couldn’t fully participate in the intellectual community she engaged.

Riley’s philosophical overview centers on Cavendish’s metaphysics. She argues that everything, including human minds, is material, using everyday observations—like hunger (“hangry” states) and cognitive decline in old age—as evidence that mental life depends on bodily processes. She also pushes against the era’s tendency to privilege soul over body, insisting that understanding the self requires studying the material body and its interactions. Her account of causality and motion is equally distinctive: bodies do not merely push each other; they communicate, with one body “prompting” another to move. Even her stance on the divine is framed through material interaction—if God is immaterial, humans cannot meaningfully know or interact with God.

Those commitments reappear inside *The Blazing World*. A kidnapping attempt near the poles strands the heroine in a new realm, where she encounters a utopian society with one language, one religion, one leader, and minimal division. She studies the world through conversation, interrogating assumptions about creation, knowledge, and scientific instruments. The narrative repeatedly turns philosophical questions into plot: microscopes and experimental tools are treated as limited, and the story resists discarding ideas that can’t be confirmed by those tools alone. Cavendish also embeds her worldview in the setting itself, populating the world with animal-figures as if matter is intelligent and conscious.

The story’s later arc escalates into world-making as a response to dissatisfaction. The empress—linked to Cavendish’s own “spirit”—tries to model a new political and philosophical order by testing the ideas of major philosophers (from Thales and Pythagoras through Plato, Epicurus, Aristotle, Descartes, and Hobbes), only to reject them as unworkable. Her own materialist philosophy becomes the foundation for a functioning world. The ending returns to Cavendish’s personal life and promises further writing, including plays that her original world would not publish but the Blazing World would welcome—an implicit argument that speculative fiction can secure the readership and dialogue Cavendish was denied.
