A Short Poem
Two experts, to explicate Meaning,
Penned a text called "The Meaning of Meaning",
But the world was perplexed,
So three experts penned next
"The Meaning of Meaning of Meaning".
— Douglas R. Hofstadter
I really must re-read Gödel, Escher, Bach: an Eternal Golden Braid. Michael Wilson's notes on G:E:B are interesting.
