The 23 enigma

The "23 Enigma" refers to the belief that all incidents and events are directly connected to the number 23, some permutation of the number 23, or a number related to the number 23, given enough ingenuity on the part of the interpreter.

Discordianism
The "23 Enigma" in Discordianism is the belief that all events are connected to the number 23, given enough ingenuity on the part of the interpreter. It can be seen in Robert Anton Wilson and Robert Shea's Illuminatus! trilogy (there called the "23/17 phenomenon"), Wilson's Cosmic Trigger I: The Final Secret of the Illuminati (there called "The Law of 23s" and "The 23 Enigma"), Arthur Koestler's Challenge of Chance, as well as the Principia Discordia. In these works, 23 is considered either lucky, unlucky, sacred to the goddess Eris, sinister, sacred to the unholy gods of the Cthulhu Mythos, or strange. Discordians regard this as a corollary of the Law of Fives.

As with most numerological claims, the 23 enigma can be viewed as an example of apophenia, selection bias, and confirmation bias. In interviews, Wilson has acknowledged the self-fulfilling nature of the 23 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."

Origins
William S. Burroughs was cited by Wilson as being the first person to notice the 23 enigma: Wilson, in an article in Fortean Times, related the following story: "I first heard of the 23 enigma from William S Burroughs, author of Naked Lunch, Nova Express, etc. According to Burroughs, he had known a certain Captain Clark, around 1960 in Tangier, who once bragged that he had been sailing 23 years without an accident. That very day, Clark’s ship had an accident that killed him and everybody else aboard. Furthermore, while Burroughs was thinking about this crude example of the irony of the gods that evening, a bulletin on the radio announced the crash of an airliner in Florida, USA. The pilot was another captain Clark and the flight was Flight 23."
