But I don’t think the notion that all ends are subjective is compatible with any system of ethics, including (as I’ve said) preference utilitarianism.
Lots of people interpret “subjective” differently. In fact, I’m discussing this matter with Charlemagne III in another thread. When I say morality is subjective, I mean that all moral codes assume at least one moral/value as axiomatic. In other words, you cannot derive an “ought” from an “is”, but you can derive it from another “ought”. And since any choice of axioms cannot be justified, by definition, it follows that neither of us can prove the other wrong on some “absolute” basis if we choose different axioms. (A good example of this sort of thing is the various types of geometry. It would be nonsensical to try to argue that Euclidean geometry is right and elliptic geometry is wrong, since they differ due to the choice of axioms.)
For example, I could use utilitarianism to prove that the greatest happiness principle is right and your axioms are wrong, but that would be a circular argument, because the very use of utilitarianism entails assuming that principle over others.
Ah, yes, rule utilitarianism. May I ask you two questions:
(1) Is “stealing is wrong” one of the rules you recommend?
Given your second question, I know where you’re going with this. But to consider the question in its own right, I would say that we need to specify what “stealing” is. Is it stealing to take my friend’s car keys from him so that he can’t drive drunk? Can a person own something if they lack the competence to use it responsibly? If not, then that would suggest an answer to your next question about terrorist threats.
(2) Is it permissible to steal in order to stop a terrorist threat?
If we overlooked the possible event of a terrorist threat in our initial consideration of the rule, we would surely revise it in the face of this new information. If you don’t like complicating a rule, then maybe we could arrange a provisional hierarchy where rules can be bypassed when other rules take precedence (not unlike our legal system). Nothing changes fundamentally, though. All rules are still accountable to the standard set by the greatest happiness principle.
I agree that humans aren’t naturally monogamous. What does that have to do with morality, though?
By itself, being natural proves nothing, and we seem to agree on that much. It is suggestive of something, though. Pleasure is the body’s way of reinforcing biologically desirable behaviors. Since our brains–especially men’s brains–are wired to have a powerful sex drive that encourages promiscuity, that will be a source of pleasure for us, at least on average. Pleasure doesn’t immediately translate to happiness, and we certainly don’t allow ourselves to act on every impulse anyway, but still…it is suggestive that monogamy may not be the best formula for happiness.
Of course, social conditioning has by now complicated the issue of what causes pleasure/happiness greatly, so the point may be moot.
But I’m interested to see how much this behavior declines as the stigma is lifting.
Another possibility is that being born gay diminishes someone’s prospects for happiness right off the bat. If that is indeed the case, then the question becomes whether gay sex exacerbates the problem. But I don’t remember if you agree with the premise that people may be born gay.
Get me that study, and have it prove your point, and I will shut up. You will convince me.
Happiness is notoriously hard to study directly. The obvious method would be to just conduct a survey and ask people to gauge their happiness, but the very act of monitoring one’s own happiness seems to affect it. And even if it didn’t, emotions do not lend themselves well to measurement. Suppose we were both asked to gauge our happiness with 10 being happiest and 1 being most miserable. Maybe we have different ideas of how much 10 should be. To me, 10 might be winning the lottery and to someone else it may be graduating high school or getting married. Those aren’t comparable. Even if 10 were defined beforehand it would still cause problems, because we may not value whatever 10 represents equally.
Why should other people satisfy my preferences, in such a case?
If I get my way and I still suffer from it, usually one of two things happened: 1) I miscalculated. I did not foresee the consequences of what I wanted. 2) I had multiple preferences that conflicted with each other.
(1) really doesn’t have a solution, and crops up in every moral code. Sometimes we have to make judgment calls and, in the face of incomplete information, we goof. It happens. My proposed adjustment to utilitarianism where we fall back on rules when uncertainty is great would mitigate this, however. (2) is a result of human nature; our preferences are bound to collide given their number and breadth. The solution would be to try to understand yourself as well as possible, something many moral codes advocate. We could make someone else the arbiter of whether or not a given outcome will increase one’s happiness, but usually you are the best judge of what you want.
