You put Y in the wrong place in step 2 of your analogy and thats completely broken any relation to mine.
I would say:
1. over the long term monkeys like to be healthy
2. bananas promote health in monkeys
3. therefore monkeys are drawn to banana habitats.
I have no idea if that leads to an actual morality in monkey societies. We seem to presume not we've defined morality as explicit rules. With humans we know we have moral rules that are passed along through explicit conditioning in parenting, culture, religion.
Oh, sorry, I misunderstood. You seem to be running towards Philippa Foot's paper, "Morality as a System of Hypothetical Imperatives."
Two revised arguments, only one of which utilizes the "long term" idea, which seems superfluous:
1. Humans prefer to be mobile.
2. Cars provide for mobility.
3. Therefore, humans will buy cars.
4. Over the long term, humans prefer to maintain a diet which includes sufficient sodium levels.
5. Long term observation teaches us that granulated salt is an ideal way to maintain sufficient sodium levels.
6. Therefore, humans are going to learn to efficiently produce granulated salt.
Again I ask: What in the world does any of this have to do with morality!? My conclusion is unchanged: Okay, cool. We just made a descriptive observation about reality. Of course this has nothing to do with morality. "They will behave in such-and-such a way" is not a moral statement.
We seem to presume not we've defined morality as explicit rules. With humans we know we have moral rules that are passed along through explicit conditioning in parenting, culture, religion.
This is the first time you've mentioned explicit rules. What do they have to do with anything? Did you mean to write 3a instead of 3?
3. therefore we are going to do Y
3a. Therefore, we are going to mandate explicit rules in favor of Y
I still think its wrong. Long term satisfaction often goes directly against our desires (hedonism), which is precisely why we need to charge the culture with normative rules that carry emotional weight.
No, you're not accepting what I said and "still" maintaining that it is wrong. You're denying my correction. At the end of the day you're just redefining hedonism to be something that doesn't care about long term desires/satisfaction. As already noted, you don't understand hedonism, and are substituting a strawman, pseudo-hedonism. Hedonism by no means limits itself to short-term whims or desires.
We could stretch the term "hedonism" to include aiming to satisfy the desire even for the Kingdom of God. OK. Congrats for breaking the word hedonism to make a point.
John Piper has actually written in favor of Christian hedonism. It doesn't break the word. It seems that you have confused a specific school of morality (hedonism) for the whole of morality.
