It's "convenient" in the sense of giving us a general way of talking about how to make decisions. It's "convenient" in that it is set up in such a way to encode not just what you prefer more than other stuff, but how much more, etc...
Lets us then also take advantage of whatever decision theory theorems have been proven, and so on...
As far as "virtue of achieving a desirable goal", "desirable", "virtue", and "achieving" would be doing all the heavy lifting there. :)
But really, my point was simply the original comment was stated in such a way as to imply "maximizing utility" was itself a moral philosophy, ie, the sort of thing that you could say "I consider that immoral, and instead care about personal virtue". I was simply saying "huh? utility stuff is just a way of talking about whatever values you happen to have. It's not, on its own, a specific set of values. It's like, I guess, saying 'what if I don't believe in math and instead believe in electromagnetism?'"
You'll have to forgive me because I am economist by training and mentions of utility have very specific references to Jeremy Bentham.
Your definition of what the term "maximizing utility" means and the Bentham definition (who was the originator) are significantly different; If you don't know what it is then I will describe it (if you do, sorry for the redundancy).
Jeremy Bentham devised Felicific calculus which is a hedonistic philosophy and seeks as its defining purpose to maximize happiness. He was of the opinion that it was possible in theory t...
As promised, here is the "Q" part of the Less Wrong Video Q&A with Eliezer Yudkowsky.
The Rules
1) One question per comment (to allow voting to carry more information about people's preferences).
2) Try to be as clear and concise as possible. If your question can't be condensed to a few paragraphs, you should probably ask in a separate post. Make sure you have an actual question somewhere in there (you can bold it to make it easier to scan).
3) Eliezer hasn't been subpoenaed. He will simply ignore the questions he doesn't want to answer, even if they somehow received 3^^^3 votes.
4) If you reference certain things that are online in your question, provide a link.
5) This thread will be open to questions and votes for at least 7 days. After that, it is up to Eliezer to decide when the best time to film his answers will be. [Update: Today, November 18, marks the 7th day since this thread was posted. If you haven't already done so, now would be a good time to review the questions and vote for your favorites.]
Suggestions
Don't limit yourself to things that have been mentioned on OB/LW. I expect that this will be the majority of questions, but you shouldn't feel limited to these topics. I've always found that a wide variety of topics makes a Q&A more interesting. If you're uncertain, ask anyway and let the voting sort out the wheat from the chaff.
It's okay to attempt humor (but good luck, it's a tough crowd).
If a discussion breaks out about a question (f.ex. to ask for clarifications) and the original poster decides to modify the question, the top level comment should be updated with the modified question (make it easy to find your question, don't have the latest version buried in a long thread).
Update: Eliezer's video answers to 30 questions from this thread can be found here.
