Science Fiction Before Science: Cavendish and the Foundations of a Genre

Abstract

This essay shows that Margaret Cavendish was more than a precursor to science fiction (sf); she was a foundational architect of its speculative logic. Challenging origin stories that center Mary Shelley’s Frankenstein (1818), it situates Cavendish within a longer, accretive history of speculative writing and reads her work as an early contribution to the sf megatext. Against the rise of Baconian empiricism and the institutional authority of the Royal Society, Cavendish develops satire and fancy as epistemic strategies that interrogate experimental science, gender hierarchies, and claims to absolute knowledge. Through texts such as The Blazing World (1666) and Poems and Fancies (1653), she models imaginative worldbuilding as a method of inquiry grounded in cognitive estrangement and speculation rather than technological mastery. Yet, she also offers readers a generative blueprint for constructing alternative worlds of their own. By reframing speculation as intellectual critique, Cavendish anticipates modern sf's investment in alternative cosmologies, provisional knowledge, and the transformative power of imagination.
