Discordianism
The Principia Discordia states that "All things happen in fives, or are divisible by or are multiples of five, or are somehow directly or indirectly appropriate to 5"—this is referred to as the Law of Fives. The 23 Enigma is regarded as a corollary of this law, since 2+3=5. It can be seen in Robert Anton Wilson and Robert Shea's The Illuminatus! Trilogy (therein called the "23/17 phenomenon"), Wilson's Cosmic Trigger I: The Final Secret of the Illuminati (therein called "The Law of fives" and "The 23 Enigma"), Arthur Koestler's Challenge of Chance, as well as the Principia Discordia. In these works, 23 is considered lucky, unlucky, sinister, strange, or sacred to the goddess Eris or to the unholy gods of the Cthulhu Mythos.
As with most numerological claims, the enigma can be viewed as an example of apophenia, selection bias, and confirmation bias. In interviews, Wilson acknowledged the self-fulfilling nature of the enigma, implying that the real value of the Laws of Fives and Twenty-threes lies in their demonstration of the mind's power to perceive "truth" in nearly anything.
When you start looking for something you tend to find it. This wouldn't be like Simon Newcomb, the great astronomer, who wrote a mathematical proof that heavier than air flight was impossible and published it a day before the Wright brothers took off. I'm talking about people who found a pattern in nature and wrote several scientific articles and got it accepted by a large part of the scientific community before it was generally agreed that there was no such pattern, it was all just selective perception."In the Illuminatus! Trilogy, he expresses the same view: that one can find a numerological significance to anything, provided "sufficient cleverness."
