A novice asked the master: “I have a program that sometimes runs and sometimes aborts. I have followed the rules of programming, yet I am totally baffled. What is the reason for this?”
The master replied: “You are confused because you do not understand the Tao. Only a fool expects rational behavior from his fellow humans. Why do you expect it from a machine that humans have constructed? Computers simulate determinism; only the Tao is perfect.
The rules of programming are transitory; only the Tao is eternal. Therefore you must contemplate the Tao before you receive enlightenment.”
“But how will I know when I have received enlightenment?” asked the novice.
“Your program will then run correctly,” replied the master.
