“Two prime ministers are sitting in a room discussing affairs of state. Suddenly a man bursts in, apoplectic with fury, shouting and stamping and banging his fist on the desk. The resident prime minister admonishes him: ‘Peter,’ he says, ‘kindly remember Rule Number 6,’ whereupon Peter is instantly restored to complete calm, apologizes, and withdraws.”
After a number of similar scenes occur, “the visiting prime minister addresses his colleague: ‘My dear friend, I’ve seen many things in my life, but never anything as remarkable as this. Would you be willing to share with me the secret of Rule Number 6?’ ‘Very simple,’ replies the resident prime minister. ‘Rule Number 6 is ‘Don’t take yourself so damn seriously.’ ‘Ah,’ says his visitor, ‘that is a fine rule.’ After a moment of pondering, he inquires, ‘And what, may I ask, are the other rules?'”
“‘There aren’t any.'”
-Rosamund and Benjamin Zander,
The Art of Possibility (2000, p.79)
Is it number 6 to emphasize that as one rule among many, it doesn’t take itself so seriously? (Meta-Rule Number 6.)
