It's more logic than anything else, but
Godel, Escher, Bach is a wonderful book.
That one looks really interesting! I think I am going to try to find it.
Look for Douglas R. Hofstadter. He's basically
the authority on recursion and self-reference. All of his books are good, but I think
GEB is probably the best starting point.
"How to find out about self-reference:
Ask yourself what is self-reference.
If you know, you're done.
If you don't, ask the person that is one step closer to Douglas Hofstadter."
