@Cmdr:
You did a very good job of describing Hedonism. You need to go back and read up more on Utilitarianism however.
If you can avoid causing harm/pain, then that trumps any level of pleasure you give by your action.
Allowing two people to die by not killing a third is the more ethical argument under Utilitarianism. Under Hedonism, however, you should murder to save 11 lives. (The average corpse has enough material to save 11 lives, at least that’s what I’ve been told.)
Remember, this is the GREATEST GOOD. Not how much good can be done if we just allow ourselves to do harm. The only time it is ethical to do harm is if, and only if, all choices result in harm and then it is ethical only to do those actions that cause the least amount of harm.
Hedonism and utiliarianism are very closely related because they both place “pleasure” as the end goal. Heodnism, though, is very self-centered. Under hedonism, I should kill Bill Gates and steal all his money, to bring about the most pleasure for myselkf.
Utilitairnism is doing the act that brings about the MOST pleasure. under utilitrianism, I should kill Bill Gates and distribute his money to as many people I can to bring about the most pleasure. A utilitarian would reprimand a hedonist who simply stole the money for their own benefit- thats not bringing about the most pleasure!
Also, a hedonist would kill someone and harvest their organs for their own beneift. A utilitarian would do so with no benefit at all to themselves, as long as the number of lives saved outnumbers the people killed.
Since we usually have qualms abot killing people for theior organs (even if more lives can be saved), utilitarisnism has some problems, which is why you see “rule” and “act” utilitarinsim.
