3.1.2 - Naturalism and Utilitarianism
Can "right" be translated into the production of pleasure and "wrong" into the production of pain? Ethical naturalism says moral claims refer to natural features of the world, and utilitarianism supplies a concrete test case. Through Bentham's utility and Mill's account of happiness, we will explain this reduction and evaluate it using moral disagreement, measurement and Moore's naturalistic-fallacy challenge.
The Meta-Ethical Claim
Meta-ethics asks a step-back question about morality. It is not first asking, "Should this person tell the truth?" or "Should this law be changed?" It is asking what moral language itself means when people use words such as right, wrong, good, bad, ought, and duty.
Meta-ethics
Meta-ethics is the study of the meaning, truth-status, source and justification of moral claims.
In this AQA point, naturalism gives one answer. It says moral claims can be understood by reference to natural features of the world: features that can, in principle, be experienced, observed, investigated, compared or discussed without appealing to a mysterious non-natural moral property.
Ethical naturalism
Ethical naturalism is the meta-ethical view that moral properties or moral meanings can be explained in terms of natural properties or facts.
AQA's chosen example is utilitarianism. Here the natural property is the production of pleasure or pain. On this view, to call an action right is to say that it causes, tends to cause, or is justified by pleasure, happiness or utility. To call an action wrong is to say that it causes, tends to cause, or is judged by pain, unhappiness or disutility.
The key move is a translation of moral language into natural language:
| Moral word | Naturalist utilitarian meaning in this AQA point |
|---|---|
Right | What causes pleasure, happiness or utility |
Wrong | What causes pain, suffering or unhappiness |
| Moral evidence | Consequences for sentient beings, rather than an invisible moral quality |
This is why the lesson belongs in meta-ethics. Utilitarianism is usually a normative theory about how to act, but AQA also uses it here as a naturalist account of what right and wrong mean.
Utilitarian Naturalism
Utilitarianism is a teleological theory: it judges actions by their ends or consequences. In its classical form, the morally relevant consequence is utility, usually understood through pleasure, happiness, pain and unhappiness.
For this lesson, Bentham and Mill are useful source anchors, but the AQA row names Utilitarianism, not a full Bentham-and-Mill comparison. Use them to understand the naturalist meaning of right and wrong.
| Scholar/source card | Content |
|---|---|
| Jeremy Bentham, An Introduction to the Principles of Morals and Legislation | Bentham makes pleasure and pain foundational for moral and legal reasoning. The principle of utility approves or disapproves actions according to their tendency to increase or decrease happiness. |
| John Stuart Mill, Utilitarianism | Mill explains the Greatest Happiness Principle: actions are judged by whether they promote happiness, with happiness understood as pleasure and absence of pain. |
| AQA vocabulary link | AQA describes utilitarianism as a teleological, normative ethical theory and as an example of ethical naturalism. |
| Why it matters here | Utilitarianism turns right and wrong into claims about consequences in human and sentient experience. |
| Possible challenge | Even if pleasure and pain are real experiences, it remains debatable whether they fully define moral rightness and wrongness. |
The naturalist force of utilitarianism is that it gives moral language a public test. Instead of saying, "This is right because I intuit that it is right," the utilitarian naturalist asks about the effect on happiness and suffering. That makes moral discussion more evidence-based: people can argue about likely consequences, the scale of benefit, the seriousness of harm, and who is affected.
But this also narrows morality. If right means pleasure-causing and wrong means pain-causing, then other possible moral concerns have to be fitted into that framework. Justice, promise-keeping, rights, intentions and character matter only if they affect pleasure, pain or happiness. That gives the theory clarity, but also creates pressure.
The Decision Rule
As a decision rule, utilitarian naturalism can be put like this:
- Identify the possible actions.
- Identify who will be affected.
- Consider the likely pleasure, happiness, pain or suffering each action will cause.
- Give each person's welfare impartial consideration.
- Judge the action right if it produces the best balance of pleasure over pain.
This is not the same as saying, "Whatever pleases me is right." Classical utilitarianism is impartial. One person's pleasure is not automatically worth more because it is mine, yours, religious, secular, powerful or familiar. The relevant natural facts are the consequences for everyone affected.
That impartiality is why utilitarianism can be attractive as a moral theory. It gives a shared question:
Which action produces the best consequences in terms of pleasure and pain for those affected?
For a meta-ethical lesson, however, notice the deeper claim underneath the rule:
| Level | What utilitarianism says |
|---|---|
| Normative level | Choose the action that produces the best consequences in pleasure/pain terms. |
| Meta-ethical level | The meaning or truth of right and wrong is tied to those natural consequences. |
If a student only writes that utilitarianism "chooses happiness", the answer stays too thin. The AQA meta-ethics point is sharper: utilitarianism is naturalist because it treats moral rightness and wrongness as analysable through pleasure and pain.
For this lesson, the crucial move is from "utilitarianism seeks happiness" to "utilitarianism treats right and wrong as natural facts about pleasure and pain."
Why This Counts As Naturalism
Naturalism is easiest to understand by seeing what it refuses to do. It refuses to treat moral words as pointing to a special non-natural property that cannot be investigated through ordinary experience. It also refuses to make moral truth depend only on command, intuition or personal feeling.
Utilitarian naturalism says moral claims can be made meaningful by connecting them to facts such as:
- what people and other sentient beings experience
- whether an outcome increases pleasure or reduces pain
- whether an action promotes happiness or causes suffering
- whether the overall balance of consequences is beneficial or harmful
This gives naturalism a clear argument chain:
| Step | Naturalist utilitarian move |
|---|---|
| Claim | Moral words can be understood through natural facts. |
| Reason | Pleasure, pain, happiness and suffering are features of experience. |
| Application | An action is right if it causes pleasure or happiness; wrong if it causes pain or unhappiness. |
| Implication | Moral disagreement can be discussed by looking at consequences, not only by appealing to private intuition or authority. |
There is a useful distinction here. The utilitarian naturalist is not merely saying, "Pleasure is often morally relevant." Many non-utilitarians could agree with that. The stronger naturalist claim is that pleasure and pain explain what right and wrong are.
That is why this lesson sits between two neighbouring AQA ideas. Divine Command Theory grounds right and wrong in what God commands or forbids. Intuitionism treats moral values as self-evident and non-natural. Utilitarian naturalism gives a different answer: rightness and wrongness are anchored in natural consequences.
Strengths And Pressure Points
Utilitarian naturalism has real strengths.
| Strength | Why it can be persuasive |
|---|---|
| Clarity | It gives moral terms a clear meaning: pleasure-causing or pain-causing. |
| Public reasoning | It asks for evidence about consequences, not only private feeling. |
| Practical relevance | Pleasure, pain, happiness and suffering are central to ordinary moral concern. |
| Impartiality | It can challenge selfishness because everyone's welfare counts in the calculation. |
The same clarity creates pressure points.
| Pressure point | Why it matters |
|---|---|
| Measurement | Pleasures and pains can be hard to predict, compare or quantify. |
| Reduction | Morality may include more than pleasure and pain, such as justice, dignity, rights or promise-keeping. |
| Minority harm | Maximising overall pleasure could seem to justify serious harm to a few people. |
Meaning of good | A critic may argue that even if an action causes pleasure, it is still meaningful to ask whether it is truly good. |
G. E. Moore's criticism is especially important for meta-ethics. Moore argued that naturalist theories wrongly define good in terms of some natural property. Applied to utilitarianism, the worry is this: if good simply meant pleasure, then asking "Is pleasure good?" would be empty. But it still seems like an open and meaningful question. That suggests, for Moore, that good is not identical with pleasure.
This does not automatically defeat utilitarian naturalism. A utilitarian can reply that pleasure, happiness and suffering are not random natural facts; they are exactly the kinds of experiences morality should care about. But Moore's challenge shows the central AO2 issue: naturalism is strong when it gives moral language a shared empirical anchor, and weak if that anchor looks like a reduction of morality to only one kind of fact.
AO1 To AO2 Bridge
The strongest answers on this point do not treat AO1 and AO2 as separate boxes. They use accurate content to generate a judgement about naturalism.
| Accurate AO1 point | AO2 judgement it can support | Objection to test it |
|---|---|---|
| Naturalism explains moral terms through natural facts. | This makes moral language clearer and more open to evidence. | It may reduce moral value to something too narrow. |
| Utilitarianism identifies right with pleasure or happiness and wrong with pain or unhappiness. | This gives a practical and humane criterion for moral judgement. | Pleasure and pain may be difficult to measure or may not capture justice. |
| Classical utilitarianism is impartial. | It can challenge selfish or biased moral reasoning. | Impartial maximisation may still permit harm to individuals. |
| Moore challenges the definition of good by natural properties. | This gives a serious meta-ethical criticism of naturalism. | A naturalist may reply that moral facts can still be natural without being simplistically defined. |
A basic paragraph might say:
Utilitarianism is naturalist because it says right actions cause pleasure and wrong actions cause pain. This is good because pleasure is important, but it is weak because pain is bad.
That is accurate but thin. It repeats the wording without showing the meta-ethical issue.
A stronger paragraph would say:
Utilitarianism is an example of ethical naturalism because it explains moral rightness and wrongness through natural consequences: pleasure, pain, happiness and suffering. This is persuasive because it gives moral claims a public basis; people can discuss likely consequences rather than relying only on private intuition. However, the theory is vulnerable to Moore's open-question style criticism. Even if an action causes pleasure, it still seems meaningful to ask whether it is good, which suggests that goodness may not be identical with any natural property. Therefore utilitarian naturalism is strong as a clear and practical account of moral language, but weaker if morality includes values that cannot be reduced to pleasure and pain.
Useful synoptic links later:
- Divine Command Theory: compare a naturalist account of right/wrong with a command-based account.
- Intuitionism: compare naturalism with the claim that moral values are self-evident and non-natural.
- Bentham and Kant: later comparison work can use this lesson, but this lesson itself is about meta-ethical naturalism, not the full Bentham/Kant topic.
