IB Philosophy 4.2.2 Foundations for Moral Judgements Notes

The Question of Moral Foundations

1. Topic 4.2.1 examined the origins and nature of moral values, asking where they come from and whether they are more than preferences. This topic narrows the focus to a more specific question: what foundations can be offered for moral judgements? When someone claims that an action is right or wrong, what grounds that claim, and can such claims be justified?

1. The answer depends on what kind of foundation we think moral judgements rest upon: reason, emotion, natural law, or the social and physical environment in which moral agents find themselves.
2. The four foundations identified by the syllabus, rationality, emotion, natural law, and environment, represent the major historical answers to this question.
   1. Each proposes a different source of moral authority: rationalists ground morality in reason, sentimentalists in feeling, natural law theorists in the structure of the cosmos, and environmentalists in the material conditions of human life.
3. Alongside these four foundations, the syllabus asks students to understand two key meta-ethical distinctions: cognitivism versus non-cognitivism, and naturalism versus non-naturalism.
   1. These distinctions are about what kind of thing a moral claim is: can it be true or false (cognitivism), or does it express something other than a belief, like a feeling or a command (non-cognitivism)?
   2. And if moral claims can be true or false, are moral properties the same thing as natural properties like pain or pleasure (naturalism), or are they a completely different category of fact that cannot be reduced to anything in the physical world (non-naturalism)?
4. Two specific theories, intuitionism and emotivism, are also required. Intuitionism holds that moral facts are real and grasped through a direct moral perception; emotivism holds that moral statements express feelings rather than facts.
5. Each will be examined in detail in the sections that follow.
6. The relationship between this topic and 4.2.1 should be clear: 4.2.1 asked where moral values come from (their origins), while this topic asks what justifies moral judgements (their foundations).
   1. A moral value may originate in cultural conditioning, but the question remains whether it can be rationally justified once we reflect on it. Origins and foundations are distinct philosophical questions.
7. This topic connects directly to the overarching Unit 4 question: "Are there fundamental moral principles that apply in all situations?"
   1. If moral judgements have rational or natural law foundations, then universal moral principles may exist.
   2. If they are grounded in emotion or environment, their scope may be limited to particular cultures or individuals.
   3. The foundations we accept determine the scope of moral authority.
8. The discussion here also prepares the ground for 4.2.3 (Ethical Language), which will examine the meaning of moral statements in greater detail.

Four Foundations: Rationality, Emotion, Natural Law, and Environment

1. Rationality as a foundation for moral judgements has its strongest advocate in Immanuel Kant (discussed in 4.1.1 and 4.1.3), who argued that moral principles are derivable from pure practical reason alone, independent of desire, culture, or empirical circumstances.
2. The categorical imperative is a test of rational consistency: a maxim is moral if and only if it can be universalized without contradiction, making the rational structure of the maxim itself the ground of its moral authority.
3. The rationalist position supports moral universalism: if moral principles are grounded in reason, and reason is the same for all rational beings, then moral truths are universal and necessary.
   1. This is the strongest possible foundation for moral judgements, but it faces the objection (raised by Hume in 4.2.1) that reason alone cannot motivate action.
4. If morality requires motivation, and reason provides only knowledge, then some role for emotion seems inescapable, which limits the claim that rationality alone can serve as a complete foundation for moral judgements.
5. Hume's famous claim (examined in 4.2.1) that reason is the slave of the passions asserts that all moral motivation ultimately derives from feeling, not rational argument.
6. Environment as a foundation refers to the view that moral systems are shaped by the material, social, and ecological conditions in which human communities develop. Karl Marx argued that moral ideas are part of the ideological superstructure determined by the economic base of society.
7. On this view, moral judgements reflect the interests of the dominant class rather than universal truths.
8. The sentimentalist position faces the objection that emotions are unreliable and variable: different people feel differently about the same situation, and feelings can be distorted by prejudice, self-interest, or cultural conditioning.
   1. If morality rests on emotion, it is difficult to explain how objective moral criticism is possible, since one cannot argue that someone's feelings are "wrong" in the way one can argue that a belief is false.

Natural Law, Environment, and the Plurality of Foundations

1. Natural law theory, associated with Thomas Aquinas and the broader Thomistic and Aristotelian traditions, holds that moral principles are grounded in the rational structure of nature itself. Human beings have a natural end or purpose (telos), and moral goodness consists in fulfilling that purpose.
2. Natural law is discoverable through reason applied to human nature and does not depend on divine revelation alone, which gives it a philosophical standing independent of theological authority.
3. The natural law tradition provides a foundation that is both rational and objective: moral principles are not merely human conventions but reflect the order of reality. However, critics challenge the assumption that nature has a teleological structure (a built-in purpose).
4. If the natural world is value-neutral, as much modern science suggests, then the attempt to derive moral norms from nature commits the naturalistic fallacy (deriving "ought" from "is"), which undermines the entire natural law project.
5. The environmental perspective is compatible with moral relativism: if moral systems are products of material conditions, then different conditions will produce different moralities. This view is historically influential but faces the objection that it undermines the possibility of moral progress.
6. If all morality is merely a reflection of material conditions, then the claim that slavery is wrong (regardless of economic system) loses its philosophical foundation.
7. Most contemporary philosophers recognize that moral judgements likely involve multiple foundations working together:
   1. reason may provide structure and consistency,
   2. emotion may provide motivation and moral sensitivity,
   3. natural law may identify objective human goods, and
   4. environmental factors may explain why moral systems take the particular forms they do.
8. The philosophical challenge is to determine which foundation, if any, provides the ultimate justification for moral judgements rather than merely contributing a partial explanation.

Cognitivism, Non-Cognitivism, and the Great Debate

1. The distinctions between cognitivism and non-cognitivism, and between naturalism and non-naturalism, are the core tools for evaluating the foundations discussed above. These distinctions are not about what is morally right but about what kind of thing a moral judgement is: can it be true or false?
2. Cognitivism holds that moral judgements are truth-apt: they express beliefs that can be true or false. When someone says "Torture is wrong," they are making a claim about the world that is either correct or incorrect.
3. Non-cognitivism denies this, holding that moral judgements express attitudes, emotions, or commands rather than beliefs. On this view, "Torture is wrong" expresses disapproval or issues a prescription rather than stating a fact.
4. Within cognitivism, naturalism holds that moral properties are identical to or reducible to natural properties (properties studied by the natural sciences). For example, a naturalist might identify "good" with "that which promotes well-being."
5. Non-naturalism holds that moral properties are real but impossible to define in natural terms: goodness exists independently of the physical world but cannot be reduced to facts about pleasure, survival, or anything science can measure, making ethics its own distinct domain of knowledge.
6. Intuitionism, developed by G.E. Moore in Principia Ethica (1903) and further refined by W.D. Ross (discussed in 4.1.3), is the clearest example of a theory that says moral facts are real and objective (cognitivism) but cannot be defined in terms of the natural world (non-naturalism).
   1. Moore argued that "good" is a simple, unanalysable property that cannot be defined in terms of any natural property.
   2. Any attempt to define good in naturalistic terms (as pleasure, as evolutionary fitness, as divine command) commits what Moore called the open question argument: it is always meaningful to ask "X is pleasant, but is it good?" because goodness cannot be identified with any natural property.
7. Moore's intuitionism holds that we know moral truths the same way we know that yellow is yellow: not by argument or experiment, but by a direct, immediate moral intuition that simply sees it.
   1. We do not infer that cruelty is wrong; we simply see that it is, through a faculty of moral intuition.
8. Ross extended this by arguing that we intuit a set of prima facie duties (non-maleficence, fidelity, justice, beneficence) whose truth is self-evident to any reflective moral agent.

Intuitionism and Emotivism

1. W.D. Ross refined Moore’s intuitionism by identifying specific prima facie duties: obligations that hold unless overridden by stronger competing duties. These include fidelity (keeping promises), non-maleficence (not harming), beneficence (doing good), justice (fair distribution), and gratitude (repaying kindness).
2. Unlike Moore’s “single unanalysable good”, Ross offered a practical system: when duties conflict, the morally mature agent weighs them using judgement rather than a mechanical formula.
   1. For example, a duty of fidelity (keeping a promise to meet a friend) might be overridden by non-maleficence (stopping to help an injured stranger).
3. This makes Ross’s intuitionism more actionable than Moore’s, though critics argue the lack of a priority ranking among duties leaves the system incomplete.
4. Emotivism, developed by A.J. Ayer and refined by Charles Stevenson, holds that moral judgements express emotional attitudes rather than stating facts.
5. We can see what non-cognitivism looks like in practice: once you deny that moral statements can be true or false, the whole question of what grounds a moral judgement shifts. There is no fact to ground it, only an attitude.
6. Intuitionism preserves the objectivity of moral judgements but struggles to explain how we can verify moral intuitions or resolve disagreements between people whose intuitions differ.
7. Emotivism explains the motivational force of moral judgements (they express attitudes that move us to act) but struggles to account for the fact that moral reasoning seems to involve more than mere emotional expression.
8. The question of whether moral judgements are cognitive or non-cognitive has direct implications for the normative theories examined in 4.1. If cognitivism is correct, then the moral claims of Kant, Mill, and Aristotle are candidates for truth or falsehood.
9. If non-cognitivism is correct, then competing moral theories are not really disagreeing about facts but expressing different attitudes or prescriptions.
