The "Matrix" films makes numerous references to films and literature, and to historical myths and philosophy including Buddhism, Vedanta, Advaita Hinduism, Christianity, Messianism, Judaism, Gnosticism, existentialism, obscurantism, and nihilism. The films' premise resembles Plato's Allegory of the cave, René Descartes's evil demon, Kant's reflections on the Phenomenon versus the Ding an sich, Zhuangzi's "Zhuangzi dreamed he was a butterfly", Marxist social theory and the brain in a vat thought experiment. Many references to Jean Baudrillard's "Simulacra and Simulation" appear in the first film. Baudrillard himself considered this a misrepresentation, although Lana Wachowski claims the point the reference was making was misunderstood. There are similarities to cyberpunk works such as "Neuromancer" by William Gibson, who has described "The Matrix" as "arguably the ultimate 'cyberpunk' artifact."
