For a long time, I wanted to ask something. I was just thinking about it again when I saw that Alicorn has a post on a similar topic. So I decided to go ahead.
The question is: what is the difference between morally neutral stimulus responces and agony? What features must an animal, machine, program, alien, human fetus, molecule, or anime character have before you will say that if their utility meter is low, it needs to be raised. For example, if you wanted to know if lobsters suffer when they're cooked alive, what exactly are you asking?
On reflection, I'm actually asking two questions: what is a morally significant agent (MSA; is there an established term for this?) whose goals you would want to further; and having determined that, under what conditions would you consider it to be suffering, so that you would?
I think that an MSA would not be defined by one feature. So try to list several features, possibly assigning relative weights to each.
IIRC, I read a study that tried to determine if fish suffer by injecting them with toxins and observing whether their reactions are planned or entirely instinctive. (They found that there's a bit of planning among bony fish, but none among the cartilaginous.) I don't know why they had to actually hurt the fish, especially in a way that didn't leave much room for planning, if all they wanted to know was if the fish can plan. But that was their definition. You might also name introspection, remembering the pain after it's over...
This is the ultimate subjective question, so the only wrong answer is one that is never given. Speak, or be wrong. I will downvote any post you don't make.
BTW, I think the most important defining feature of an MSA is ability to kick people's asses. Very humanizing.
1) "pretty large" tends to mean the same thing as "fundamental", "general", "widely binding" -- at least in my experience. E.g., "Godel's Theorem was a pretty large rejection of the Russell program."
And no, I'm not defending MacIntyre. All I'm trying to demonstrate is that his arguments against emotivism are worthy enough for emotivists to learn.
2) No. You've never heard someone say, "I may not like it, but it's still good?" For example, there are people who are personally dislike gay marriage, but support it anyway because they feel it is good.
3) Defining "moral approval" as "when people express approval using moral language" says nothing about what the term "moral" means, and that's something any ethical system really ought to get to eventually.
4) Yes: deontological systems don't give one whit about the syntax of a statement; if your 'intention' was bad, your speech act was still bad. Utilitarianism also is more concerned with the actual weal or woe caused by a sentence, not its syntatic form.
And I'm done. If you want to learn more about MacIntyre, read the damn book. I'm a mathematician, not a philosopher.
You said that emotivists you know go into "absolute denial" at point 2; how do they react to an example like this?
I would expect them to say that the people are lying or feel constrained by social conventions. In Haidt terms, they feel both fairness and disgust or violation of tradition and feel that fairness trumps tradition/purity in this instance. Or they live in a libe... (read more)
