Discordianism is a modern, chaos-centered religion founded circa 1958–1959 by Malaclypse the Younger with the publication of its principal text, the Principia Discordia. It is widely regarded as a parody religion, and has been called "Zen for roundeyes", based on similarities with absurdist interpretations of the Rinzai school. Discordianism recognizes chaos, discord, and dissent as valid and desirable qualities, in contrast with most religions, which idealize harmony and order. Eris, the Greek mythological goddess of discord, has also become the matron deity of the religion Discordianism.It is difficult to estimate the number of followers and correctly identify Discordian groups. The anarchist ethic that pervades Discordianism is reflected in an encouragement to form schisms and cabals. Additionally, few adherents hold Discordianism as their only or primary faith. Instead, Erisians tend to adopt Discordianism as a complement to other faiths.
