I used to go around saying, "I am the only person I know of who does not believe he is unique."

(Always loved deliberate irony like that.)

It's true, though. I do not believe it likely, or even statistically possible, that I have thought any thoughts not thought by someone else, and this seems to be an uncommon (but not unique) thought.

I've also been obsessed with meta, and I thought this was uncommon as well until I started reading Hofstadter.

Does any of that count?
