The red pill and its opposite, the blue pill, are popular cultural symbols representing the choice between:
The terms, popularized in science fiction culture, are derived from the 1999 film The Matrix. In the film, the main character Neo is offered the choice between a red pill and a blue pill by rebel leader Morpheus. The red pill would free him from the enslaving control of the machine-generated dream world and allow him to escape into the real world, but living the "truth of reality" is harsher and more difficult; on the other hand, the blue pill would lead him back to stay in the comfortable simulated reality of the Matrix. In politics and culture, the red pill analogy is sometimes used by , reactionary or counterculture communities, including the androsphere, neoreactionary movement, GamerGate and conspiracy theorists.
The 1999 film The Matrix, created and directed by The Wachowskis, makes references to historical myths and philosophy, including gnosticism, existentialism, and nihilism. The film's premise resembles Plato's Allegory of the cave,René Descartes's skepticism and evil demon, Kant's reflections on the Phenomenon versus the Ding an sich, Zhuangzi's "Zhuangzi dreamed he was a butterfly", the concept of a simulated reality and the brain in a vat thought experiment.
