Getting back to the original question, if I could give three or four people a very fun weekend, I'd punch someone. If I could give one person an extremely fun weekend, I'd punch someone. I'd punch them pretty hard. I'd leave a bruise, and make them sore the next day.
Thanks, this counts as an answer for my purposes.
Most of the usual thought experiments that justify expected utilitarialism trade off fun for fun, or suffering for suffering. Here's a situation which mixes the two. You are offered to press a button that will select a random person (not you) and torture them for a month. In return the machine will make N people who are not suffering right now have X fun each. The fun will be of the positive variety, not saving any creatures from pain.
1) How large would X and N have to be for you to accept the offer?
2) If you say X or N must be very large, does this prove that you measure torture and fun using in effect different scales, and therefore are a deontologist rather than a utilitarian?
