I've been reading some encyclopedia articles on utilitarianism. As far as I can see, utilitarians have moved from (the defence of) the pursuit of happiness to the pursuit of preference satisfaction. A preference is satisfied, I suppose, when someone gets what she or he wants.
Now, I think it's reasonable that we ought to try to make people happy, at least in most cases, but I don't think it as reasonable that we ought to try to give people what they want. And anyway, I think that these are two very different ethical theories. Should we call both "utilitarianism"?
