Making a person and unmaking a person seem like utilitarian inverses
Doesn't seem that way at all to me. A person who already exists has friends, family, social commitments, etc. Killing that person would usually effect all of these things negatively, often to a pretty huge extent. Using contraception maybe creates some amount of disutility in certain cases (for staunch Catholics, for instance) but not nearly to the degree that killing someone does. If you're only focusing on the utility for the person made or unmade, then maybe (although see blacktrance's comment on that), but as a utilitarian you have no license for doing that.
A hermit, long forgotten by the rest of the world, lives a middling life all alone on a desert island. Eve kills the hermit secretly and painlessly, sell his organs, and uses the money to change the mind of a couple who had decided against having additional children. The couple's child leads a life far longer and happier than the forgotten Hermit's ever would have been.
Eve has increased QALYs, average happiness, and total happiness. Has Eve done a good thing? If not, why not?
Haven't had one of these for awhile. This thread is for questions or comments that you've felt silly about not knowing/understanding. Let's try to exchange info that seems obvious, knowing that due to the illusion of transparency it really isn't so obvious!
