As I understand it, relativism doesn't mean "refers explicitly to particular agents". Suppose there's a morality-determining function that takes an agent's terminal values and their psychology/physiology and spits out what that agent should do. It would spit different things out for different agents, and even more different things for different kinds of agents (humans vs babyeaters). Nevertheless, this would not quite be moral relativism because it would still be the case that there's an objective morality-determining function that is to be applied to determine what one should do. Moral relativism would not merely say that there's no one right way one should act, it would also say that there's no one right way to determine how one should act.
It's not objective, because it's results differ with differing terminal values. An objective morality machine would tell you what you should do, not tell you how to satisfy your values. Iow, morality isn't decision theory.
Why must the two be mutually exclusive? Why can't morality be about satisfying your values? One could say that morality properly understood is nothing more than the output of decision theory, or that outputs of decision theory that fall in a certain area labeled "moral questions" are morality.
Because that isn't how the term "morality" is typically used by humans. The "morality police" found in certain Islamic countries aren't life coaches. The Ten Commandments aren't conditional statements. When people complain about the decaying moral fabric of society, they're not talking about a decline in introspective ability.
Inherent to the concept of morality is the external imposition of values. (Not just decisions, because they also want you to obey the rules when they're not looking, you see?) Sociologically speaking, morality is a system for getting people to do unfun things by threatening ostracization.
Decision theory (and meta-decision-theory etc.) does not exist to analyze this concept (which is not designed for agents); it exists to replace it.
Morality is about all of these things. and more besides. Although "outer" morality as embodied in moral codes and moral exemplars is definitely important, if there were no inner values for humans to care about in the first place, no one would be going around and imposing them on others, or even debating them in any way.
And it is a fact about the world that most basic moral values are shared among human societies. Morality may or may not be objective, but it is definitely intersubjective in a way that looks 'objective' to the casual observer.
"Morality" is used by humans in unclear ways and I don't know how much can be gained from looking at common usage. It's more sensible to look at philosophical ethical theories rather than folk morality - and there you'll find that moral internalism and ethical egoism are within the realm of possible moralities.
Morality done right is about the voluntary and mutual adjustment of values ( or rather actions expressing them).
Morally done wrong can go two ways, one failure mode is hedonism, where the individual takes no notice of the preferences of others:; the other is authoritarianism, where "society" (rather, its representatives) imposes values that no-one likes or has a say in.
Note the word objective.
An objective morality machine would tell you the One True Objective Thing TheAncientGeek Should Do, given your values, but this thing need not be the same as The One True Objective Thing Blacktrance Should Do. The calculations it performs are the same in both cases (which is what makes it objective), but the outputs are different.
You are misusing "objective". How does your usage differ from telling me what i should do subjectively? How can.true-for-me-but-not-for-you clauses fail to indicate subjectivity? How cam it be coherent to say there is one truth, only it is different for everybody?
A person's height is objectively measurable; that does not mean all people have the same height.
"True about person P" is objective.
"True for person P about X" is subjective.
Subjectivity is multiple truths about one thing, ie multiple claims about one thing, which are indexed to individuals, and which would be contradictory without the indexing.
In this discussion, I understand there to be three positions:
The 'objective' and 'subjective' distinction is not particularly useful for this discussion, because it confuses the separation between 'measurable' and 'unmeasurable' (1+2 vs. 3) and 'universal' and 'particular' (1 vs. 2+3).
But even 'universal' and 'particular' are not quite the right words- Clippy's particular preference for paperclips is one that Clippy would like to enforce on the entire universe.
No one holds 3. 1 is ambiguous; it depends on whether we're speaking "in character" or not. If we are, then it follows from 2 ("there is one objectively measurable value system, namely mine").
The trouble with Eliezer's "metaethics" sequence is that it's written in character (as a human), and something called "metaethics" shouldn't be.
Agreed. What I should do is a separate thing from what you should do, even though they're the same type of thing and may be similar in many ways.
What you morally should do to me has to take me into account, and vice versa. Otherwise you are using morality to mean hedonism.
Saying it's true-for-me-but-not-for-you conflates two very different things: truth being agent-relative and descriptive statements about agents being true or false depending on the agent they're referring to. "X is 6 feet tall" is true when X is someone who's 6 feet tall and false when X is someone who's 4 feet tall, and in neither case is it subjective, even though the truth-value depends on who X is. Morality is similar - "X is the right thing for TheAncientGeek to do" is an objectively true (or false) statement, regardless of who's evaluating you. Encountering "X is the right thing to do if you're Person A and the wrong thing to do if you're Person B" and thinking moralitry subjective is the same sort of mistake as if you encountered the statement "Person A is 6 feet tall and Person B is not 6 feet tall" and concluded that height is subjective.
See my other reply.
Indexing statements about individuals to individuals is harmless. Subjectivity comes in when you index statements about something else to individuals.
Morally relevant actions are actions which potentially affect others
Your morality machine is subjective because I don't need to feed in anyone else's preferences, even though my actions will affect them.
Other people's preferences are part of states of the world, and states of the world are fed into the machine.
Not part of the original spec!!!
Not so! Rather, "X is the right thing for TheAncientGeek to do given TheAncientGeek's values" is an objectively true (or false) statement. But "X is the right thing for TheAncientGeek to do" tout court is not; it depends on a specific value system being implicitly understood.
"X is the right thing for TheAncientGeek to do" is synonymous with "X is the right thing for TheAncientGeek to do according to his (reflectively consistent) values". You may not want him to act in accordance with his values, but that doesn't change the fact that he should - much like in the standard analysis of the prisoner's dilemma, each prisoner wants the other to cooperate, but has to admit that each of them should defect.
Same mistake, Only actions that affect others are morally relevant, from which it follows that rightness cannot be evaluated from one person's values alone.
Maximizing ones values solipsitically is hedonism, not morality.
Notice I didn't use the term "morality" in the grandparent. Cf. my other comment.
