I think you are correct, provided your own assumptions that politics is about building a good society for the subjects/voters/citizens, ie: that politics is a large-scale extension of ethics.

However, most people don't share the LW notions of ethics, so real-world politics has tended to be more sort of, "What people resort to when fundamental ethical disagreements occur over terminal values or moral epistemology." I think this view is more historical: politics has been an extension of diplomacy, a continuing attempt to prevent Hobbes's "war of all against all" (or rather, a war of Moral Greens versus Moral Blues versus Moral Grays versus Moral Reds, etc for however many different fundamental moral views are current in the population).

What are LW ethics? DIfferent individuals seem to adopt every possible theory except Divine Command, AFAICT.

And how would it help?

I don't think there is even that exception.

ETA: There have been long term participants who had that ethical system (and associated beliefs). Both because they were simply religious and because they went loopy with convoluted meta reasoning and ended up back there.

I suppose people use the term "LW ethics" to refer to Eliezer's moral indexicalism (Is there a name for the position that has actually been adopted into more wide-spread use here?) plus consequentialism, but I agree with the objection to the suggestion of uniformity.

Subjectivism.

Really? In that case, I'm strongly against using that, because the term "subjectivism" seems ill-defined, not very illuminating, and has a bunch of wrong connotations. In particular, as I read him, Eliezer does think that we are all talking about the same thing, that we have a shared referential intention, and that disagreement is therefor substantial and about the truth-value of a definite proposition that has a truth-value. (Which is precisely the reason why I think his theory is wrong.)

The consequentialism is of the utilitarian variety , which isn't particularly compatible with subjectivism/indexicality. So there's two theories.

Of course; one is a metaethical theory, the other is an ethical theory. But I think the two are very compatible, simply because they're orthogonal.

By whom? It seems well-defined by professional philosophes to me.

To whom? It is not a force of nature that makes words have connotations. The individual brings whatever connotations they bring.

In particular, as I read him, Eliezer does think that we are all talking about the same thing, that we have a shared referential intention, and that disagreement is therefor substantial and about the truth-value of a definite proposition that has a truth-value. (Which is precisely the reason why I think his theory is wrong.)

Then what happened to the indexicality you mentioned? (And for which there is independent evidence, such as "Yudkowsky!good")? If the truth values of ethical claims are indexed to individuals, where does the disagreement come from?

Of course; one is a metaethical theory, the other is an ethical theory. But I think the two are very compatible, simply because they're orthogonal.

Subjectivism, by itself is a metaethical theory which yields object-level results when an individuals prefrences are plugged in.

Utilitarianism, by itself is a metaethical theory which yields object-level results when a societies preferences are plugged in.

What I want is not automatically what the greatest Number wants, so they are incompatible.

By whom? It seems well-defined by professional philosophes to me.

Well, the Stanford Encyclopedia doesn't give a unambiguous definition of it; it says that it's about "mind-(in)dependence", but says that there is some disagreement about what precisely that means. Intuitively, I feel Eliezer's view is not illuminatingly called subjectivist because for him, moral statements are simply about the properties of a certain abstract algorithm.

Interstingly, I found this piece, according to which Eliezer's view is clearly relativist.

Then what happened to the indexicality you mentioned?

Imagine two humans standing besides each other and disagreeing about the truth of "it's bright here". (Assume they're both blind and so only have indirect evidence, otherwise disagreement doesn't really make sense or would necessarily be about the standard of brightness, which is a tricky issue in itself.) Since they're in the same place, they are using the indexical "here" with the same reference. For Eliezer, as I understand him, the same thing happens when two humans disagree about "one should do X": the indexical "should" has the same reference when used by either of them.

Not responding to the last section because I'm not following it. I see your point that the whole utilitarianism/CEV/preferences business - in my view, the ethical as opposed to the metaethical part - is somewhat muddled up in Eliezer's writing, though.

That SEP page is curious, because this:

According to such a view, it is possible that when John asserts “Stealing is wrong” he is saying something true, but that when Jenny asserts “Stealing is wrong” she is saying something false.

would seem to be trivially true, if they are in fact talking about sentences there. Just have Jenny be speaking a foreign language that contains the same symbols with a different meaning. By that standard, anything anyone says ever could safely be considered relative.

On the other hand if they're talking about propositions then it would seem to be trivially false, because propositions have truth values.

Comment author: Creutzer 07 February 2014 11:02:25AM * 3 points [-]

They are talking about propositions, and the point is that the sentence "Stealing is wrong" expresses different propositions when uttered by different people, just like "I'm sleepy" does. That's what indexicality is!

Comment author: nshepperd 07 February 2014 05:58:48PM * 0 points [-]

That's what I meant by "talking about sentences". Any sentence can express different propositions when uttered by different people. Just have people speaking different languages. So clearly "means different things when said by different people" isn't half specific enough to have any dire metaethical implications.

It doesn't follow from the fact that propositions have truth values that the SEP quote is trivially false. "Stealing is wrong" as asserted by John and "Stealing is wrong" as asserted by Jenny both have truth values, they just don't have the same truth values. You need another premise.

Comment author: nshepperd 07 February 2014 06:14:45PM * 0 points [-]

By "if they're talking about propositions" I meant assuming that they mean “Stealing is wrong” to refer to a particular proposition (ie. asserting that John and Jenny are stating the same proposition) rather than a sentence (string of words).

It's not trivially false because philosophers take a sentence that appears to be in certain language to have its normal meaning in that language.

It's not trivially true because identical sentences can have different truth values when spoken by different people, eg "my name is John"

I guess the idea is that assertions about morality are not propositions in that sense?

Comment author: TheAncientGeek 07 February 2014 10:59:04AM * 1 point [-]

"Indexed to something mind-dependent " and "indexed to something about an individual" are not both more precise than your "indexical"

I don't find it illuminating to be told that morality is about an abstract algorithm , since that does not tell me whether the algorithm is defined at the individual, group, or universal level; nor whether it is cognactively accessible; nor whether it is mind dependent

You have said that moral claims are indexical, and also that "should" always has the same referent .hat is it so where does the last indexicality come from...what makes it vary?

Let me take another try at the last section: ethics and metaethics aren't orthogonal . Not all combinations work. As object level ethics, utilitarianism is incompatible with metaethics that is indexed to or relative to individuals.

Utilitarianism is an ethical theory, not a metaethical theory.

Comment author: Eugine_Nier 07 February 2014 07:12:36AM -2 points [-]

Utilitarianism with a particular utility function is an ethical theory.

Comment author: blacktrance 07 February 2014 03:36:37PM -1 points [-]

I'm using "utilitarianism" in the standard philosophical sense, not in the LessWrong "uses utility functions" sense. As such, it already has a utility function - the utility functions of everyone that exists.

Isn't there an entire ethics Sequence?

Never mind, I'll bugger off.

Comment author: TheAncientGeek 05 February 2014 03:44:07PM -2 points [-]

Isn't there an entire ethics Sequence?

It seems to consist of someone thinkign aloud and changing their mind.

Comment author: Creutzer 05 February 2014 04:39:34PM 1 point [-]

Wait, did I miss something? Which change of mind are you referring to?

Comment author: TheAncientGeek 05 February 2014 07:53:26PM 0 points [-]

Not in the sense that he announced a change of mind. More an overall drift.

Comment author: Creutzer 05 February 2014 09:53:03PM 3 points [-]

Well, drift from where to where, then?

Comment author: TheAncientGeek 06 February 2014 01:35:15PM 0 points [-]

The situation would be much better if there were some discernable end point or trajectory to the drift.

Comment author: Creutzer 06 February 2014 02:18:25PM * 0 points [-]

You do realise that, being asked twice, you have failed to provide any substantiation of the claim(s) you're making...

Comment author: TheAncientGeek 06 February 2014 03:37:28PM -1 points [-]

I don't think claims about how something seems to me need independent substantiation.

That there is a definite and uniform LW ethics is not a default: such a claim needs support itself.

Huh. Might as well stake my own position then. Humean sentimentalist/emotivist here, what up?

The logical structure of ethical claims.
