Parfit on Moral Disagreement: Part 2
Notes and Thoughts on Moral Disagreement as Discussed in Parfit's "On What Matters" Ch. 34
Parfit Vs Basic Argument from Disagreement
Suppose you and your counterpart are in ideal epistemic conditions. You are aware of and agree on all the non-normative facts yet your opinions differ on what the true moral belief is. In a way, we can see this in the abortion debate and in the vegetarianism debate, to name a few. Since both parties in these debates often agree on the non-normative facts, we should not rationally suppose that our intuitions about the issue are true. The basic idea is that, given epistemic parity, there is no compelling reason, beyond ego, to suppose that our normative belief is the correct one or that our opponent wrong.
Parfit says that the Intuitionist response must be that in such situations where everyone knows all the relevant non-normative facts there wouldn't be disagreement over moral assessment. In such ideal conditions, everyone would agree on the normative belief. For example, if everyone on all sides of the abortion debate agreed on and knew all the relevant non-normative facts, the Intuitionist has to say that they'd all agree on what is the correct normative belief regarding abortion.
Hmmm...I'm not too sure what to think of that claim. Anyhow, the bottom line here is that Parfit is making an empirical claim. He's saying that, given all the relevant epistemic information, we'd make the same moral judgments.
The cool thing about empirical claims is that they can be tested. Remember way back in the Intro of Part 1 I axed you to answer the trolly questions? video of trolley problem Well, here's the thing. There's a branch of philosophy called xphi (as in "experimental philosophy") where one of the things they do is psychology-like experiments to test testable philosophical claims. (check out this link to see some cool xphi experiments)
There are some xphi experiments that test people's intuitions on moral questions. It's been a while since I read it but I remember reading something on an xphi experiment testing people's intuitions on the trolly thought experiments. I don't remember the details but I do remember that there wasn't unanimity in moral judgments for what to do in the trolly problems. I'll have to look it up later for my paper but I think something like 3/4 said they'd pull the lever and 3/4 said they wouldn't push the fat man. The odd thing about the thought experiment is despite the outcome being the same (1 person dies to save 5), most people aren't consistent with their answer.
So how does this apply to Parfit's claim about er'body having the same intuitions given perfect information? It seems to falsify it because, in the thought experiment, everyone has the same relevant non-normative facts, yet a statistically significant portion of respondents disagree with the majority.
There's a possible reply for Parfit here. In his senario he says that not only would agents have all the same non-normative facts but they'd also be using the same normative concepts (and understand the relevant arguments and not be affected by distorting influences). So, his way out is that he can say, despite the fact that er'body agrees about the non-normative facts in the trolley experiment, they aren't all starting with the same normative concepts. That explains the different outcomes.
Lets pause for a second and look at what Parit (might) mean here by "shared normative concepts". Given what he has said in previous chapters we can assume that included in this category of concepts is the notion of external reasons in favour of/against an action.
A quick review of Parfit's notion of "reasons": For Parfit, a reason is a fact, awareness of which counts in favour of/against a particular action. This is in contrast to Williams' notion of a reason which is a psychological account of motivation: I.e., a reason for action is when an agent had a psychological desire to be satisfied. If an agent has no psychological desire to be satisfied, then they have no reason for an action. As I have discussed in several other posts, Williams' notion of reason is purely internal to the agent whereas, Partit's is external to the agent and objectively true to all rational creatures.
Another thing we might include in Parit's cluster of normative concepts in the idea of intrinsic goods; I.e., things that are good in themselves, not because they lead to further things. I'm going to hypothesize that he's including this too.
"I Am a Computer" (*in a robot voice)
Now here's where things get a little tricky. I could be totally wrong with this but I'm going to present an analogy to Parfit's hypothesis. Imagine a moral decision making computer in the future that has a cool robot voice. It says, "I am a computer" a lot. Not only does it talk in a cool robot voice but it solves moral dilemas for us. How might it do this? One thing it needs is the data. On Parfit's model that will be the non-normative facts. The next thing it needs is algorithms to interpret and weigh the data. These will be the normative concepts. The program will provide the logical structure, which for Parfit will be the arguments (maybe?). So, Parfit is saying that if two properly functioning computers with cool robot voices had all these elements in common, they give the same output.
Problem 1: Which normative concepts?
Hmmm...he's probably right but I'm not sure this is a very meaningful claim. It seems tautologous to say that provided we shared the same normative concepts we'd come up with the same normative conclusions. Duh! In a way it seems like he's side-stepping the whole problem.
One of the main reasons for which we have moral disagreement is because we don't share the same normative concepts. Furthermore, there doesn't seem to be any objective way to arbitrate between competing normative concepts without already presupposing some prior meta-normative concepts.
Parfit might reply that reasons allow us to arbitrate between competing normative. But I think this assumes everyone is going to be equally responsive to the same reasons. I'm not sure that will be the case.
Problem 2: Non-testability
I don't think this claim is testable. Lets grant that in making a moral decision, two or more people meet all the right epistemic conditions and are using the same normative concepts. There's still another problem. It is highly unlikely that 2 or more people will ever share every normative concept. Maybe Bob has normative concepts {A, B, C, D, E} and Mary has normative concepts {A, B, C, D}. In some cases, concept E won't play any determining role in the outcome; in others it might.
Of course, Parfit can reply that just because it's not actually a testable claim doesn't make it false. He'd be right, but it doesn't make it true either. It makes it untestable, and so difficult to know how things would actually play out.
Parfit can also reply that in the case where E is a relevant factor, the disputants don't share a relevant concepts, and so his hypothesis is right. After all, his claim is that if disputants shared relevant normative concepts, they'd get roughly the same moral answer. He has a strong response here, but how significant is the claim that if people share relevant normative concepts, they will get a similar answer?
Problem 3: Problem of relevant concepts and weight.
Suppose we run the trolley experiment on some people. We also check to see if they use the same normative concepts. One possible problem is that while they agree on which concepts are relevant, they might not agree on how the concepts should be applied or weighed. For example we ask: "are you applying external reasons to your analysis" and they answer in the affirmative. It's possible that 2 people might agree on using the normative concept of external reasons, but they might disagree on what those reasons are and how they should be weighed in a particular situation.
Parfit might respond that people can make mistakes in their application and weighing of normative concepts. Mathematicians can disagree on things but they are still able to recognize mathematical truths. That there are occasional mistakes doesn't mean there is no objective truth, it only means that someone has made a mistake. The method needn't be infallible to support an Intuitionist account of moral realism--we're human, we're bound to err. We could be deficient is our appraisal of which non-normative facts are relevant, how and which normative concepts should be applied, and there may be distorting influences (like culture/upbringing). These facts only show that we can get it wrong, not that there are no objective normative truths.
A problem with this reply is that it is non-falsifiable. Anytime there's a moral disagreement, Parfit can say either that someone has just made a mistake or that the two parties have slightly different normative concepts and one of them has the wrong one. There's always some sort of ex post facto explanation open to him.
Distorting Influences
Parfit partly acknowledges this problem by saying we can't simply claim that someone has been subject to a distorting influence anytime they end up with a belief that differs from our own. He needs to give a more careful description of what constitute distorting influences. He gives self-interest as a legitimate distorting factor of which we should be wary in our moral reasoning. True dat...unless you're an egoist, in which case it is an elucidating factor...different normative concepts...oh! snap!
Parfit concludes this section by setting the bar for what is required for the Intuitionist account of moral realism to be true. "Intuitionists need not claim that, in ideal conditions these disagreements would all be completely resolved. But they must defend the claim that, in ideal conditions, there would not be deep and widespread moral disagreement."
I can dig that. However, a problem I foresee is how Parfit will show that convergence over values is a product of there being objective moral truths instead it being a product of cultural convergence or evolutionary forces. Both stories could account for moral agreement. What would really be compelling for the moral realist's case is to give examples of widely divergent cultures that share significant moral values. That, in my estimation, would carry some weight.
Note: I wrote this before reading the entire chapter. Later in the chapter Parfit makes stronger defenses of his claims and addresses some of my worries. Why does he have to be so reasonable? How am I supposed to write a critical paper about someone I'm starting to agree with? Curse you Parfit!

The Arguments from Queerness and Relativity (Mackie Part 2)
Other Mackie Articles
Mackie on Subjectivity vs Objectivity
Mackie Intro and Second vs First Order Ethics
Overview
Do objective moral values or principles exist? Or are we dancer? When someone says, "it's wrong to do x" or "you ought not to do x" it seems as though they are referring to something objective about or in the act. That is, we are referring to some real quality or property in the act. Mackie says this is a quirk of language and that moral properties and values don't exist in any real sense (i.e., the way we use language makes it seem like we are referring to something but actually we aren't). He gives two arguments for his position: the argument from relativity and the argument from queerness.
Argument from Relativity
This argument is fairly straight forward:
P1. It's an empirical fact (that's science!) that many cultures around the world both historically--and now--have very different moral concepts, many of them in genuine opposition to each other.
[P1* However, disagreement alone isn't enough to prove there are no objective moral values, so I'll offer a further argument.]
P2. (Argument from Arrow of causation and constructivist account of morality) One way to explain the difference in moral judgments is that a culture's moral values arise out of how they live their lives. The ways of living comes first, the moral judgments come after, not the other way around. For example, if a culture finds polygamy morally acceptable, it's because that's how they live. A community doesn't first decide what types of marriage are appropriate, then modify its behavior. If we accept this interpretation, then moral values aren't objective; instead they are a consequence of social structures.
P3. The moral realist has another way to explain moral differences which is to assume that there are objective moral facts. The difference between moral values in cultures/moments in history arises because some cultures are (somehow) more aware of the true moral values than others. Some cultures just have better perception of moral qualities than do others.
P4. (Abductive Argument) However, if moral values are objective, giving an account of how entire cultures can fail to perceive them is not going to be easy (or plausible). Instead we should adopt the constructivist explanation: i.e., we construct our values based on the normal behaviours and arrangements in our particular culture--rather than there being objective moral values that people somehow (mis)perceive.
Conclusion: Because the constructivist account is a more plausible explanation for the wide variety of often conflicting moral positions we observe, we should say that there are no objective moral values.
Possible Objection 1: Moral Reformers Exist
Moral judgments aren't merely a matter of conforming to a social standard. There are cases of moral change and reform throughout history. For example, the abolition of slavery, the civil rights act, advance of women's and, recently, gay etc...
Reply 1: Move Toward Consistency
There's aren't changes in the moral code, rather, they are moves toward consistency in the moral code. For example, the moral argument for the abolition of slavery was that slavery was inconsistent with the pre-existing ideals of all people being born free and equal before the law.
Possible Objection 2: Instances of Universal Principles
The specific rules vary across cultures however they are instances of a more general universal rules. E.g., do whatever will bring about the greatest amount of good. So, of course what brings about the greatest amount of good will vary across different living circumstances. But this doesn't undermine the fact that the general rule is universally true. And so, morality does have objectively true principles.
Mackie's Reply: It's Only a Partial Counter
Accepting the above line of argument means that the specific laws are only derivatively and contingently objectively true. That is, their objectivity relies on their being instances of universal laws. Since the specific laws are dependent on local circumstances that means that if the local circumstances change, the objective truth of the specific laws will change. But this doesn't reflect what people think about their local moral rules. They think that their specific rules are objectively true and not merely derivative of universal rules or contingent on circumstance.
For example, in some cultures they believe it's wrong to eat pork. They don't think this is wrong because it's an instance or derivation of a more general universal rule. They just think it's wrong to eat pork "period". Also, they don't think that if circumstances changed, it would be OK to eat pork. In other words, the specific rather than a general rule is considered to be objectively true. And it's objective truth isn't derivative of a more general rule, nor is it contingent on circumstance.
Argument from Queerness
This argument has two parts, one metaphysical (to do with the nature of something's existence) and one epistemological (how we come to know something).
Metaphysical Argument: Suppose there were objective moral values: real qualities that were part of the world--in short, they exist. What would they be made of? Do they inhere in matter? Can I taste them? Touch them? What colour are they? How is it that we can sense them but not explain their properties? It seems they would be queer entities or properties indeed! (Not that there's anything wrong with that--some of my best friends have queer properties).
Epistemological Argument: Setting the metaphysical issue aside and continuing with our supposition, by what faculty might we come to know these queer qualities? If I can't see, touch, taste, smell, or hear them, by what sense faculty do I come to know them?
It seems any theory that says moral values are objective must give us some sort of account of how it is we come to know them. And to reply that ethical thinking occurs simply by sitting down and having an 'intuition' turns ethical thought into a travesty of a mockery of a sham. What about application of reason? conceptual analysis? deliberation?
The only possible good defense to this argument a realist can offer is to somehow show that these supposed moral qualities/properties can be known empirically.
So, what might these real moral properties be like? According to Mackie, they'd have to be something like Plato's Forms. A quick and dirty explanation of Plato's forms is that they are the perfect abstract notion of all qualities and things. Well, not only are they abstract notions but they actually exist somewhere, in some sense. Consider the Form of the Good. This is the ideal goodness to which we all ought to strive; and although it is an ideal, it also somehow exists. In what way do ideals objectively exist?
The Problem of Motivating Force (Another metaphysical argument)
Anyhow, Mackie's argument isn't specific to Plato's forms. He argues that any moral realist position would be susceptible to the following argument: According to Mackie, for a moral realist the properties of the "goodness" or "badness" of an act must not only be sensible but must also motivate action.
For example, recognizing an act as "good" is not simply a matter of perceiving that property in something and thinking, "huh, that thing has 'goodness' in it--cool," it also necessarily provides the knower with a direction and motive for action. So, when we recognize something as good, it should also incite us to action. That is, knowing something is good should also motive us to pursue it. And the same will apply for all moral values (if we perceive the property of 'badness' in something, it must also motivate us to avoid it).This meta-ethical position is called "existence internalism" (not to be confused with and not related to internalism in epistemology).
But why should the realist accept this condition imposed by Mackie? Why can't the realist say that it is possible to recognize 'goodness' in something and not have it motivate action? I suppose the realist could do that, but then the realist has to give up the claim that moral values/properties of an situation or act do motivate action toward the good, which is a move they probably don't want to make. It relegates moral properties to the same status as 'red' and 'heavy'.
More Queerness...
In a particular action/situation, what would be the relationship between an objective moral quality and the act's/situation's natural features?
Take the example of an act of cruelty. Why do cruel acts also have the property of 'wrongness'? The typical answer is that the act's wrongness is a consequence of its cruelness: it is wrong because it's cruel. But the realist can't use this explanation because their argument is that moral values are in the act as natural properties, so appealing to a causal relation (x is wrong because it's cruel) is off limits. Cruelness and wrongness have to exist independently of one another.
Furthermore, how do we rule out that judging a particular cruel act as wrong isn't simply a consequence of our culture? There is a wide range of cultural opinions on what constitutes, for example, 'wrongness' in regards to treatment of animals. Isn't an account of differing cultural values a better explanation for the diversity of views (rather than some groups' moral faculty being more accurate than others')?
The realist might reply the wrongness supervenes on the cruelty of an action; that is, the property of wrongness is a property that comes about wherever there is the property of cruelty. But how do we explain the notion of properties having properties? It seems a little...mmmm...queer! Is it not a more likely account that our application of the term 'wrong' to cruel acts is a consequence of our subjective response to cruel acts--not that we are perceiving some additional natural property in the act.
The realist's position in regards to supervenience of properties is actually quite defensible. In contemporary philosophy (especially of mind) the notion of supervening properties is almost unanimously accepted. For example, the property of consciousness supervenes on the physical properties of the brain. This notion can plausibly be extended to acts.
So, there you have it, the arguments from relativity and from queerness, both against moral realism. Whaduyuthink? Are you ready to give up the chimera of objective moral qualities? I should add that giving up objective moral values doesn't mean giving up morality, just objective morality.
