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.
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 to create a literal formula which gives optimized preferences such that it maximized happiness for the individual. This is the foundation for all utilitarian ethics as each seeks to essentially itemize all preferences.
Virtue ethics for those who do not know is the Aristotelian philosophy that posits: each sufficiently differentiated organism or object is naturally optimized for at least one specific purpose above all other purposes. Optimized decision making for a virtue theorist would be doing the things which best express or develop that specific purpose - similar to how specialty tools are best used for their specialty. Happiness is said to spring forth from this as a consequence, not as it's goal.
I just want to know, if it is the case that he came to follow the former (Bentham) philosophy, how he came to that decision (theoretically it is possible to combine the two).
So in this case, while the term may give an approximation of the optimal decision, if used in that manner is not explicitly clear in how it determines the basis for the decision is in the first place; that is unless, as some have done, it is specified that maximizing happiness is the goal (which I had just assumed people were asserting implicitly anyhow).
Okay, I was talking about utility maximization in the decision theory sense. ie, computations of expected utility, etc etc...
As far as happiness being The One True Virtue, well, that's been explicitly addressed
Anyways, "maximize happiness above all else" is explicitly not it. And utility, as discussed on this site is a reference to the decision theoretic concept. It is not a specific moral theory at all.
Now, the stuff that we consider morality would include happiness as a term, but certainly not as the only thing.
Virtue ethics, as you describe it... (read more)
