1) "yearn to discover your errors"?
For the second sentence, "If you hate illusion, seek to be disillusioned."
I don't have a rephrasing of the third, but something expressing the idea of "taking joy in the real" might work.
For the second sentence, "If you hate illusion, seek to be disillusioned."
If I were to seek to be disillusioned my approach would be to acquire as many illusions as possible as fast as possible while also exposing myself to an intense yet unstable stream of real world stimulus. (The original version does not provide this kind of 'game me' exhortation.)
I was meditating on the word "disillusionment" the other day, and it stuck me as odd that it has such a negative connotation... doesn't being disillusioned mean that you see a truth that was previously hidden from you by a mirage of falsehood? The human-universal negative emotional response to finding out you were wrong seems counterproductive in the extreme, and I'm still working towards eliminating it from my mind. So I crafted this brief litany, and I think that with some help from the LW community it could become a useful tool for rationalists, much like the Litanies of Tarski and Gendlin. My "first draft" is:
"If you love truth, learn to love finding out you were wrong. If you hate illusion, learn to love disillusionment. If your emotions are not appropriate to your values, do something about it!"
What say you?
