The veneration of Eris, a.k.a. Discordia; widely popular among hackers. Discordianism was popularized by Robert Shea and Robert Anton Wilson's novel Illuminatus! as a sort of self-subverting Dada-Zen for Westerners — it should on no account be taken seriously but is far more serious than most jokes. Consider, for example, the Fifth Commandment of the Pentabarf, from Principia Discordia: “A Discordian is Prohibited of Believing What he Reads.” Discordianism is usually connected with an elaborate conspiracy theory/joke involving millennia-long warfare between the anarcho-surrealist partisans of Eris and a malevolent, authoritarian secret society called the Illuminati. See Religion in Appendix B, Church of the SubGenius, and ha ha only serious.
