I hereby declare that "gugglefweeps" mean people like Richard Feynman, Albert Einstein, me, Carl Friedrich Gauss, and Johann Sebastian Bach. It's great being a gugglefweep.

Less obliquely: Where does this term "post-rationalist" come from, who applies it to all these people, and is there meant to be any sort of suggestion that there's much in common between the thinking of the people allegedly described by it? (From what you've said so far, there's little reason to think there is.)
