Anyone Who'd Visit a Psychiatrist Ought to Have His Head Examined


Fun with self-reference....

I've long thought that "self-reference" and "recursion" are among the most important topics out there (and I'm in good company, since they've been central to a lot of Douglas Hofstadter's work ;-). They straddle, in crucial ways, the fields of linguistics/cognitive science and math/logic. So I was delighted this week to see Ben Orlin do his humorous take on self-reference (and even Gödel's Incompleteness Theorem) and chop it down to size:

And Alexander Bogomolny also has an entertaining page of examples:

...and then there's always this xkcd classic:


...Lastly, always remember that, "All generalizations are false, including this one" (Mark Twain).
