That isn't maximising my utility. That is maximising the utility of some other thing in the future.
All maximizations are going to take place in the future: they already haven't taken place up to the present.
Your complaint is that "that thing", the future you, isn't similar enough to the present you. Fair enough. It's hard to say anything about maximizing your utility as it is now if we assume zero knowledge about your utility function.
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?
