I’m pretty sure you are wrong about this. Read Bentham. Pleasure is the goal of hedonism, sure, but utilitarianism was originally a hedonistic moral theory.
i’m sure it has always been lambasted as amounting to hedonism by its opponents since it was invented. but utilitarians have generally sought to refute that equivalence.
en.wikipedia.org/wiki/Utilitarianism
"Utilitarianism (also: utilism) is the idea that the moral worth of an action is determined solely by its usefulness in maximizing utility/minimizing negative utility (utility can be defined as pleasure, preference satisfaction, knowledge or other things) as summed among all sentient beings. It is thus a form of consequentialism, meaning that the moral worth of an action is determined by its outcome. The most influential contributors to this theory are considered to be Jeremy Bentham and John Stuart Mill.
Utilitarianism was described by Bentham as “the greatest happiness or greatest felicity principle.”[1] Utility, the good to be maximized, has been defined by various thinkers as happiness or pleasure (versus suffering or pain), although preference utilitarians define it as the satisfaction of preferences. It may be described as a life stance, with happiness or pleasure being of ultimate importance."
it appears that Bentham (as well as Mill following him) conceived of utilitarianism in terms of happiness while “various other thinkers” have defined utility as pleasure, but i have no interest in defending any particular utilitarian philosopher and what they may have said.
because it can mean so many different things, i think it is best to reserve “utilitarianism” as a term that refers to the specific philosophical writings of the millses and bentham. i have mostly been using the term “consequentialism” as a more general term for one the sorts of ethical theories to be contrasted with natural law ethics.
i don’t think there is anything we ought to ever be concerned about in the name of morals other than the actual or potential consequences as changes in states of consciousness for beings capable of experiencing happiness and suffering. that makes me some sort of a consequentialist, but i don’t want to subscribe to any historical school of thought since i don’t know exactly what has been said in the past. i agree with the arguments laid out by sam harris in the moral landscape.
This is like saying, “Given that species are constantly changing, don’t bother trying to hunt moose, you’ll never pin one down”;
no, it’s not. it’s like saying “
Given that species are constantly changing, why should we think that they have a moral duty not to change but rather to be true to their natures?”
or, “Given that nation-states are constantly evolving, don’t bother trying to determine what the laws of the state are”;
no, it’s asking,
why should we think that the way the laws are now should decide what the laws ought to be in the future?
or, “Because of plate tectonics what is now dry land will probably someday be ocean, so it’s nonsense to claim that there are parts of the Earth that are land and parts that are ocean.”
no, it is to point out the non sequitur of saying that
a part of earth is now land means that the part of earth ought to always remain land and not be used as a reservoir. or that if a part of the earth that is now ocean we ought not pump in sand to extend a beach or build an oil platform on it.
You’ve completely missed the point of natural law theory when you suggest it implies a “moral obligation to act in certain ways so as to maintain our species as it happens to be in a particular moment in time in this evolutionary picture” - you might as well say a cartographer’s goal is to put an end to the activity of plate tectonics.
i certainly haven’t been convinced that natural law theory has a point to miss. if certain posters in this thread are to be taken as any guide, its purpose seems to be nothing more than to find some way to argue that anal sex is immoral.
i hope you can give natural law ethics a better defense (and i’m pretty confident that you can.)
