It has been a while since I have last posted. Today I want to do a bit of a follow up on my previous post. I am going to focus specifically on providing details of why I am a moral realist.
In some sense, the moral realist position is highly intuitive - afterall we very much behave as if moral sentences have genuine force. In other senses the position is highly controversial - it is not exactly how we can access this morality. Before we begin, it is worth first outlining what I take to be the moral realist position and the intended structure of my argument.
Moral realism:= the position that ethical sentences express propositions that refer to objective (mind independant) aspects of reality. The position that ethical sentences can be genuinely true.
It's worth adding a few clarifications.
Ethical sentences are sentences that involve things like 'ethical goodness', 'moral badness' and so on. One way to frame this is to think that there might be 'ethical properties' and that an ethical sentence is one that involves these ethical properties (with no committment yet as to whether these ethical properties refer to genuine parts of reality). I'll also be using ethical and moral as semantically interchangeable.
Sentences are lexical expressions - they are the things people directly say or write. The content of a sentence is the proposition that it expresses. (We actually rely on a subclass of sentences known as declarative sentences) The same sentence can express different propositions at different contexts (e.g. 'I am here' means a different thing depending on where I am). The same proposition can also be expressed by the same sentence (think about saying the same thing in two different languages). Propositions have truth values (true / false - let's assume a binary system) and the truth values are determined by a satisfaction of certain truth conditions.
To say that ethical sentences can be genuinely true means that I think ethical sentences express propositions that have truth conditions that could be true. For it to be true means that the ethical properties or other such things involved in an ethical sentence have truth conditions that can be satisfied by objective reality.
To refine 'can' - I am not saying that all ethical sentences are true. This would be an extreme position (think 'Murder is always ethically right') but also vulnerable to contradictions (Think 'Abortion is right' and 'it is not the case that Abortion is right').
Structure of my argument
My argument is reasonably sophistcated and will be split into two primary parts (this may require multiple posts). The first part will involve an exploration of the alternatives to Moral realism and explaining why I find them unconvincing or undesirable.
The second part will address some of the common reasons why we might be sceptical about moral realism and argue that there are epistemic challenges in many similar and analogous areas that we are less sceptical about. I'm not planning to provide a full defense of moral realism - my goal is to argue that the alternatives are all problematic and that the problems of moral realism are not as bad as people might think.
Part 1:
Moral realism can be considered the conjoinment of the following separate claims:
i) Cognitive - moral sentences express propositions. Propositions can be true or false and have truth conditions. These truth conditions refer to some aspect of reality and are satisfied if they reflect this aspect of reality.
ii) Possibly true - there exist true moral sentences.
It is worth adding an aside that moral subjectivism is actually a branch of moral realism that claims that that the truth values of moral sentences is necessarily dependant on the attitudes of people. I want to express a stronger claim and talk about an objectivist brand of moral realism. I am therefore going to add a third point
iii) Objectivist - moral propositions are not subjective. The truth value of moral propositions is determined mind independantly.
Non cognitivism (deny i))
I'm now going to outline a few views that are variations of this. I'm going to start first with the denial that moral sentences express propositions. This is known as a non cognitivist position. Claims ii) and iii) are both cognitivist positions and thus are inconsistent with non cognitivism. Non cognitivism basically says that we aren't actually expressing propositional content when we talk about morality. Instead we are doing something else - for example we are expressing some kind of attitude towards something.
To a non cognitivist, a sentence like 'Murder is wrong' is simply an expression of disapproval (Boo murder!) towards murder, but is not purporting to express anything more than that. Wrong is not some kind of moral property - there is no propositional content or semantic meaning involved. Instead the focus is on the function of the sentence - what it is doing, as opposed to what it is actually saying.
I think this is the view I have analysed the least but also the view that I have heard defended the least. It is worth noting that most objections against moral realism involve the denial of ii) or iii). Denying i) goes against both of these. I personally find this position unconvincing because of the embedding problem.
Consider a sentence such as 'Adam doesn't realise that murder is wrong'. A non cognitivist would have to assess this along the lines of: 'Adam does not realise 'Boo murder!' which seems like a very strange analysis.
I'm going to move on because as I've mentioned I've never actually heard anyone defend this position, but I would be open to someone who could convince me that this view is plausible.
Moral nihilism (denying ii))
Also known as moral scepticism or error theory. This is usually framed as the claim that there are no true moral sentences, i.e. all moral sentences are false. Technically there are different versions of scepticism that differ in why they think we are not justified in believing any moral sentence. The epistemic sceptic might go down a route of lack of access to ethical properties. I'm going to focus on the error theorist for now and respond to the epistemic sceptic later.
Note it is worth clarifying the specific sense of false. They are false because (it is claimed) moral properties fail to purport to any aspect of reality. It is like if I invented a property and I went around talking about people that satisfy or do not satisfy the property. These sentences can not be true because for them to be true would require that they truth conditions about reality when in practice there are no such truth conditions in the first place.
A standard argument in favour of error theory is that if ethical properties were to exist then they would have to have some sort of mystical properties that are very much distinct from physical properties in our universe.
I think the moral error theorist is wrong, but I think it is a very tall order to directly refute them. Instead I will argue that there are some very uncomfortable conclusions that an error theorist must commit to. I will also later argue that the motivations for the error theorist (i.e. problems they see in realism) can be explained. Therefore, whilst the error theorist position is in theory plausible, it is very much undesirable and is not more explanatory than a realist position.
In term of being undesireable, the moral error theorist is saying that when we express ethical sentences ('Murder is wrong', 'Rape is wrong', 'Kindness is good') we are wrong. We are wrong in the sentence that our language involving ethical properties like 'good' or 'bad' fail to refer to any aspect of reality. We are essentially talking semantic nonsense, discussing properties that don't have real meaning.
The error theorist will usually try and offer an explanation of our behaviour. The error theorist could bite the bullet and offer no explanation but this is a serious charge. There is surely an explanation for why all of humanity would talk and take seriously these imaginary properties despite all talking about nonsense. Thus the error theorist will offer an explanation for this behaviour, which is usually framed in terms of 'usefulness'. It is useful for us humans to talk about morality because it embeds certain principles that are in some sense useful to a functional society. By selling the lie that 'Murder is wrong', society becomes more functional and things can happen. Note we have to use the word functional because we can't say that society is ethically better (as ethical doesn't exist). If people lived in constant fear of death then very little could get done.
I think this is reasonable but has some issues. The first is the rather blunt comment and acceptance that claims like 'Murder is wrong' is not actually true and is fundamentally nonsense. It is just there because it is useful for a society to impose these kinds of rules. So people either believe in these imaginary properties because they are brainwashed by society to genuinely think so (everyone is simultaneously wrong!) or they act as if these properties are real as some kind of social agreement (or a mix). The latter / mix is also problematic - as it suggests that to some extent people are consciously aware that there is some kind of lie going down. There's also the second issue that if believe this due to some kind of social agreement, it is not clear why they would choose to obey these moral principles when they had no chance of getting caught or if there were minimal impact to society. Is it worth you going out of your way to save a kid drowning a river, or to donate to a charity to help the poor in Africa? If no one knows about your actions at all, your thinking would presumably be based on how it is helping you, and here that is really not clear.
There's a sense in which it is hard to demonstrate what these moral properties really look like. However there is also a sense in which it just seems absurd to deny that certain moral claims are true.
Moral subjectivism (denying iii))
In contrast to the error theorist position, i think subjectivism is a terrible position. I think there are two versions of subjectivism that people might be interested.
1) Person dependant subjectivism
2) Culture / Society dependant subjectivism (i.e. cultural relativism)
Refuting Person dependant subjectivism
Person dependant subjectivism would ammount to claiming that the truth conditions of moral claims are somehow dependant on the person, and can shift between persons. Note that moral subjectivism is a realist position - we are very much committing to morality being real but also allowing that it has some very flexible properties.
I think there are two variants of this person dependant subjectivism. The first is the 'self-identification' position, where the truth value of a moral sentence is just dependant on what a person thinks. This position seems genuinely absurd. We're basically saying that morality is real and that the content of our sentences genuinely refers to reality. What's more, that reality is prone to change at the flick of a switch depending on what I'm thinking.
So I can go around saying 'Murder is right' (and be correct) and then change my mind whenever and say 'Murder is wrong' and still be right!
This is incredible unintuive and also fails to explain aspects of reality. Even if in practice we might accept some kind of subjectivism, the subjectivism is not so strong that it works just by flicking a switch. We don't allow people to be able to go from 'Abortion is right' to 'Abortion is wrong' and back by simply thinking it, without changing their argument somehow.
The second variant is that there are the personal subjective truth conditions are not based on self identification, but based on some kind of property about the person. The truth value of moral sentences is still fine to flick from person to person, but that's because of some facts about the person that they might not have full control of. Such facts may for example be the background of a person, e.g. their upbringing. I think this variant is slightly more plausible but also faces basically the same issues.
A murderer may have a messed up context, but does this really mean that 'Murder is right' when expressed by them?
One response is to say that moral sentences depend on the context. Someone might say that 'stealing is justified' in the context of a parent who has to steal to feed their kids, but is not justified in other kinds of contexts.
I think this is actually a fairly good argument, but also not sufficiently convincing. The problem with this is that (I argue) that moral sentences like 'stealing is unjustified' are actual unrefined expressions of a general moral law. The way we talk about 'stealing is unjustified' is similar to the way we talk about 'things fall down to the ground'. They express a general law of how things work but reality is actually slightly more complicated. Think about how a plane doesn't fall to the ground - gravity is still operating but it is able to overcome it. Similar for claims about stealing. In general stealing is wrong, but when we evaluate actual situations we express a different proposition. When I talk about the parent stealing for their child I might express the proposition 'It is justified for THIS parent to steal bread in THIS context', which could be true. The key here is that the proposition I express is fully generated by the sentence I express and fully captures the relevant details. This is still an objectivist position as long as I claim that once the proposition is fixed, the truth value remains static. It would follow that whenever the exact same proposition is expressed it still has the same truth value. The nature of moral justification is sophisticated.
Refuting cultural relativism
Let's move onto cultuarl relativism which can be understood as the view that the moralities are dependant on the culture. This is meant to express some sort of claim that different societies have different moralities. What we think is good in our country might be different to what is good for another country. Murder might be wrong for us, but in some cultures murder could be a positive thing. This helps us explain disagreement (one of the main challenges to realism)
This version of subjectivism is also quite intuitive and explanatory. It seems to explain things like cultural disagreement, whilst also allowing us to engage in a degree of epistemic modesty. We're saying that we somehow have access to our morality, but we don't profess to have understanding of someone elses. I will argue however that this position also encounters some very serious problems.
Remember that this position is a realist position.
We are allowing for claims like:
'In culture X, doing A is wrong'
'In culture Y, doing A is not wrong'
There are many questions to answer. The first, is how might this work in practice for a given individual - where is the culture applied. For example, suppose in the UK it is wrong to steal, and that in some tribe in the amazon, murder is permissible. Is it the location of the action that is relevant? If I go to the Amazon tribe is it now alright for me to muder people? What if the amazon tribe person comes to the UK, should they now follow UK rules?
Perhaps there is a rule along the lines of 'When in Rome, do as Romans do'. This is plausible and interesting, but also flawed. Consider the normative force - why is this claim saying we should do it. There's two possibilities relevant to us, either the normative force is ethical (there is an ethical reason for us to do as Romans do) or it is non ethical (e.g. it is practically beneficial for us to do this). If it is non ethical then we can ignore this statement entirely for the purpose of our argument. So let's assume that it is an ethical sentence. Where does this sentence apply? Well the claim is really a variable sentence - feel free to replace Rome with any location. For this to therefore apply across all these locations, it must be some kind of universal ethical sentence.
Now because there is an example of a universal ethical sentence does not itself undermine cultural relativism, but it does present it with serious issues. If we accept there is a universal ethical sentence, then suddenly we have to accept some kind of metaphysics of morality that applies universally. What happens if someone disagrees with 'When in Rome do as Roman's do'? Are they simply wrong - presumably they are (as we're moral realists).
There's also big issues in terms of how we establish the morality in a given culture. If we are saying morality is cultural relative, then our standards are placed at the society level. Therefore, we are essentially being moral objectivist within our society. Suppose this is true, then there's the question of whether our individuals are able to successfully access or understand the objectivism of their society. Presumably this must be possible to some extent, as we appear to operate as if other cultures at least understand their own moral principles. There is therefore the question about whether one can have moral disagreement in one's own culture. Note I am talking about genuine moral disagreement - cases where both sides express contradictory positions but no side is at fault (for example not doing enough research). If we accept cultural relativism in this way then it is vulnerable to the argument that is no non genuine disagreement. The moral rules of the society is listed and accessible and only disagreement would occur if people are not up to date with the rules (allowing that they can change with time).
Note that this version of the disagreement objection is actually just a smaller version of the objection that is faced by moral realism. Here we apply it on a societal level as opposed to on a universal level, but the argument still applies. I actually don't think this argument is particularly devastating (I think it is fine to simply say that some people are wrong and that genuine disagreement is not possible). The point is that the purported benefit of cultural relativism is that is successfully explains things like disagreement. We have argued here that it faces the same issues as moral realism!
Okay I think that's enough reasons to reject moral subjectivism. I've written so much and I haven't even got to the reasons for supporting moral realism. It is worth noting that I have previously addressed both some of the issues with realism and ways to defend in my previous posts. I've actually also addressed in this post a few of the arguments.
I'll do a brief summary here:
Objections / issues for moral realism:
1) How to access what is morally good?
2) How to deal with moral disagreement? (Response discussed above - people are just wrong)
3) Do moral properties have weird properties?
4) How can we justify our moral claims?
These are good questions to consider. They aren't decisive objections (I think the positions discussed in this post are far worse) but one should probably have some kind of view on them to be able to successfully defend their position.
