Moral Realism Vs Anti RealismQuestion 1 of 20

Imagine a possible world that has never contained any sentient beings or minds. There are only rocks, rivers, and stars. In this world, a meteor strikes a planet, causing a massive rockslide.

A moral realist who is not a divine command theorist would most likely hold that in this world, the statement 'The rockslide was morally bad' is:

true, because moral properties like 'badness' can exist independently of any minds.
false, because moral properties like 'badness' depend on the suffering or well-being of sentient creatures.
meaningless, because moral language requires a community of speakers to have content.
neither true nor false, because the concept of 'badness' is a human invention.

Question 1

Imagine a possible world that has never contained any sentient beings or minds. There are only rocks, rivers, and stars. In this world, a meteor strikes a planet, causing a massive rockslide.

A moral realist who is not a divine command theorist would most likely hold that in this world, the statement 'The rockslide was morally bad' is:

  1. true, because moral properties like 'badness' can exist independently of any minds.
  2. false, because moral properties like 'badness' depend on the suffering or well-being of sentient creatures. (correct answer)
  3. meaningless, because moral language requires a community of speakers to have content.
  4. neither true nor false, because the concept of 'badness' is a human invention.
Explanation: The correct answer is B. This is a subtle question. While moral realism posits mind-independent moral facts, most forms of realism (especially naturalistic realism) tie moral properties like 'good' and 'bad' to states of the world affecting sentient beings (e.g., well-being, suffering, flourishing). The rockslide is a purely physical event with no impact on any sentient creature, so it has no moral status. Therefore, the statement is false. A represents an extreme Platonism that few realists would hold. C and D represent anti-realist positions. The question tests whether students understand that 'mind-independent' for a realist doesn't necessarily mean 'independent of any possible conscious experience.'

Question 2

Philosopher Z states: "Moral properties, such as 'goodness,' are real and objective. However, they are not part of the natural world that can be studied by science. They are non-natural, sui generis properties that we apprehend through a faculty of rational intuition."

Philosopher Z's view is a form of moral realism, but it is vulnerable to the anti-realist objection that it:

  1. reduces moral truths to subjective preferences, making rational debate impossible.
  2. fails to explain the strong connection between making a moral judgment and being motivated to act on it.
  3. posits a mysterious faculty for knowing facts that are not empirically verifiable, which is metaphysically extravagant. (correct answer)
  4. makes moral progress impossible because it identifies truth with the conventions of a given society.
Explanation: The correct answer is C. The view described is moral non-naturalism. A primary objection to this view, often raised by anti-realists and naturalist realists, is that it is metaphysically and epistemologically problematic. It posits a realm of non-natural facts and a special, non-empirical faculty ('rational intuition') to access them, which many find unparsimonious and mysterious (this is a key part of Mackie's 'argument from queerness'). A is an objection to subjectivism, not this view. B is an objection often leveled against forms of realism (the motivation problem), but C is more specific to the non-naturalist version. D is an objection to relativism.

Question 3

J.L. Mackie's 'argument from queerness' claims that if objective values existed, they would be entities of a very strange sort, utterly different from anything else in the universe, and requiring a special faculty of moral perception to detect them. This argument is intended to undermine which of the following positions?

  1. Moral Relativism, by showing that culturally determined values are not strange at all.
  2. Moral Realism, by arguing that the metaphysical and epistemological commitments of the view are implausible. (correct answer)
  3. Emotivism, by highlighting that expressions of emotion are common and not 'queer'.
  4. Subjectivism, by suggesting that individual feelings are a straightforward part of our psychology.
Explanation: The correct answer is B. Mackie's argument from queerness is a direct attack on moral realism. It targets both the metaphysical (what kind of things would objective values be?) and epistemological (how would we know them?) aspects of realism, claiming they are too strange ('queer') to be believable. The argument does not target anti-realist views like relativism, emotivism, or subjectivism (A, C, D), as these views avoid positing the existence of such 'queer' entities and faculties in the first place.

Question 4

A philosopher proposes that the statement 'Stealing is wrong' is equivalent in meaning to the command 'Don't steal!' This view, known as prescriptivism, is a form of anti-realism. What is the most significant consequence for moral discourse if this view is correct?

  1. Moral statements can no longer be seen as a product of one's cultural upbringing.
  2. It becomes impossible to explain why people feel strongly about their moral convictions.
  3. The logical rules that apply to factual statements, such as rules of inference, cannot be directly applied to moral arguments. (correct answer)
  4. People would be less motivated to act in accordance with their moral judgments.
Explanation: The correct answer is C. If moral statements are commands (imperatives) rather than descriptions of fact (indicatives), then they are not truth-apt. Standard rules of logic operate on propositions that have truth values. For example, from 'If P then Q' and 'P', we can infer 'Q'. It's not clear how such inferences would work with commands. While philosophers have developed logics for imperatives, the direct application of standard logic is lost, which is a major challenge for understanding the structure of moral reasoning. A is a sociological observation compatible with most theories. B is false; prescriptivism can account for strong feelings. D is also likely false, as commands are inherently action-guiding, arguably strengthening the link to motivation.

Question 5

A moral fictionalist argues that morality is a useful 'fiction'—we should talk and act as if moral realism were true because it helps regulate society, even though all moral claims are, strictly speaking, false. This position shares its metaphysical view of moral claims with which theory, while differing in its recommendation for practice?

  1. Moral Non-Naturalism
  2. Cultural Relativism
  3. Emotivism
  4. Error Theory (correct answer)
Explanation: The correct answer is D. This question tests knowledge of a more nuanced anti-realist position. Moral fictionalism starts from the same metaphysical place as error theory: moral claims are propositional but systematically false because there are no objective moral facts. Where they differ is in their practical conclusion. The error theorist might suggest abandoning moral talk, while the fictionalist recommends we continue to use it as a beneficial fiction. A is a form of realism. B and C are other forms of anti-realism, but they do not hold that moral claims are false propositions; B holds they are relatively true, and C holds they are not propositions at all.

Question 6

A society transitions from a system where slavery is morally accepted to one where it is condemned as a grave injustice. What is at stake in the debate between a moral realist and a cultural relativist in interpreting this change?

  1. Whether the abolition of slavery was economically beneficial for the society in the long term.
  2. Whether the society's new moral code is more internally consistent than its old one.
  3. Whether the change can be described as genuine moral progress toward a more correct moral view. (correct answer)
  4. Whether the majority of individuals in the society now personally believe that slavery is wrong.
Explanation: The correct answer is C. The concept of 'moral progress' is a key point of contention. A moral realist can say the society has progressed by better aligning its practices with objective moral truth (i.e., the truth that slavery is unjust). A cultural relativist, however, cannot ground this claim to progress. For the relativist, the old code was 'right' for that society then, and the new code is 'right' for this society now; there is no objective standard by which to judge one as better than the other, only as different. The other options describe considerations that are either empirical (A, D) or formal (B) and do not capture the core metaphysical disagreement about the status of the moral change itself.

Question 7

Two philosophers are debating the morality of a new gene-editing technology. Philosopher A argues it is intrinsically wrong, while Philosopher B argues it is morally permissible. They appeal to principles, consequences, and intuitions, but fail to persuade one another. A moral realist would most likely interpret this persistent disagreement as:

  1. evidence that moral statements are merely expressions of emotion that lack objective truth value.
  2. an indication that the moral truth about the technology is relative to each philosopher's subjective framework.
  3. a complex epistemic challenge in discovering an objective moral fact that exists independently of their beliefs. (correct answer)
  4. proof that objective moral truths must not exist, as their existence would preclude such intractable disputes.
Explanation: The correct answer is C. Moral realism holds that objective moral facts exist, but it does not entail that these facts are easy to know or self-evident. A realist would view deep disagreement as a sign of the difficulty of moral inquiry (an epistemic problem), not as proof that there are no facts to be discovered (a metaphysical claim). A is the position of emotivism, a form of anti-realism. B describes subjectivism or relativism, another form of anti-realism. D draws a conclusion that a realist would reject; for a realist, the difficulty of discovery does not negate the existence of a fact, much like disagreements in physics don't negate the existence of physical laws.

Question 8

J.L. Mackie's 'argument from queerness' claims that if objective values existed, they would be entities of a very strange sort, utterly different from anything else in the universe, and requiring a special faculty of moral perception to detect them. This argument is intended to undermine which of the following positions?

  1. Moral Relativism, by showing that culturally determined values are not strange at all.
  2. Moral Realism, by arguing that the metaphysical and epistemological commitments of the view are implausible. (correct answer)
  3. Emotivism, by highlighting that expressions of emotion are common and not 'queer'.
  4. Subjectivism, by suggesting that individual feelings are a straightforward part of our psychology.
Explanation: The correct answer is B. Mackie's argument from queerness is a direct attack on moral realism. It targets both the metaphysical (what kind of things would objective values be?) and epistemological (how would we know them?) aspects of realism, claiming they are too strange ('queer') to be believable. The argument does not target anti-realist views like relativism, emotivism, or subjectivism (A, C, D), as these views avoid positing the existence of such 'queer' entities and faculties in the first place.

Question 9

A political debate involves two speakers arguing about the justice of a wealth tax. Speaker A calls it 'a just policy for a fairer society.' Speaker B calls it 'unjust theft.' A non-cognitivist is most likely to interpret this exchange as:

  1. a factual disagreement about the economic consequences of the tax, which can be resolved by empirical data.
  2. a clash of non-rational attitudes and attempts to influence emotion, rather than a debate over objective truths. (correct answer)
  3. a genuine moral disagreement where one speaker is correct and the other is incorrect about the objective nature of justice.
  4. evidence that the concept of 'justice' is incoherent and all claims about it are systematically false.
Explanation: The correct answer is B. Non-cognitivism (which includes emotivism and prescriptivism) holds that moral statements do not express propositions but rather attitudes, emotions, or commands. From this perspective, the speakers are not debating a factual matter of what is 'just' or 'unjust' in an objective sense. Instead, they are expressing their conflicting feelings or attitudes about the policy and trying to persuade others to adopt their stance. A treats the disagreement as purely empirical, which the non-cognitivist would deny is the whole story for moral terms. C is the moral realist interpretation. D is the error theorist interpretation, which is cognitivist, unlike the non-cognitivist view.

Question 10

A philosopher argues: "Moral claims, like 'Lying is wrong,' are genuine propositions capable of being true or false. However, they are all false, because the world simply does not contain the sort of objective prescriptive properties that would be needed to make them true." This philosopher's view is correctly classified as:

  1. realist, because it holds that moral claims have truth values.
  2. anti-realist, because it denies that any positive moral claims are true. (correct answer)
  3. non-cognitivist, because it ultimately rejects the existence of moral properties.
  4. relativist, because it makes moral truth dependent on the existence of properties.
Explanation: The correct answer is B. The view described is J.L. Mackie's error theory. It is a form of anti-realism because it denies the existence of the moral reality that would be required for moral claims to be true. A is a classic error; while the view is cognitivist (moral claims have truth values), it is not realist because it claims all such propositions are false. Realism requires that at least some positive moral claims are true. C is incorrect because the view is explicitly cognitivist, which is the opposite of non-cognitivism. D misinterprets the position; it is absolutist in its denial of moral truth, not relativist.

Question 11

Philosopher X argues: "When I call an action 'right,' I am not describing some property of the action itself. I am reporting my own feeling of approval toward it. If I approve of it, it is 'right' for me, and if you disapprove of it, it is 'wrong' for you. There is no further standard of rightness beyond these individual feelings."

The view expressed by Philosopher X is a form of anti-realism because it denies that moral properties are:

  1. connected to human emotions and attitudes.
  2. knowable through introspection or observation.
  3. capable of motivating individuals to act.
  4. objective and independent of any individual's mental states. (correct answer)
Explanation: The correct answer is D. The core of moral realism is the claim that moral facts and properties are objective and mind-independent. Philosopher X's view, a form of individualist subjectivism, makes moral properties entirely dependent on an individual's mental states (feelings of approval). Therefore, it is anti-realist precisely because it denies the objectivity and mind-independence of moral properties. A is incorrect because this view explicitly connects morality to emotions. B is incorrect because this view suggests moral properties are knowable through introspection. C is incorrect because on this view, the feeling of approval is directly tied to motivation.

Question 12

An anthropologist notes that Culture A practices infanticide as a morally acceptable way to manage resources, while Culture B considers it a heinous crime. The anthropologist concludes, "Therefore, the morality of infanticide is not a matter of objective fact, but is determined by cultural norms."

A moral realist would criticize the anthropologist's conclusion by arguing that it improperly:

  1. assumes that moral beliefs can influence a person's behavior.
  2. infers a metaphysical conclusion about the nature of morality from an observation about cultural disagreement. (correct answer)
  3. fails to recognize that some actions may be morally neutral.
  4. denies that different cultures can have different, yet equally valid, moral perspectives.
Explanation: The correct answer is B. This question targets the common argument from disagreement used to support relativism. A moral realist would argue that the anthropologist is making a logical leap. The observation that cultures disagree about morality (an empirical, anthropological claim) does not, by itself, prove the metaphysical conclusion that there are no objective moral facts. The realist would say that, just as disagreement about the shape of the earth doesn't mean it has no objective shape, disagreement about morality doesn't mean it has no objective truth. The other options are not the central realist objection. A is not a point of contention. C is irrelevant to the core argument. D is what the realist denies; they would argue that if the cultures hold contradictory views, at least one of them must be mistaken.

Question 13

A philosopher argues: "Moral claims, like 'Lying is wrong,' are genuine propositions capable of being true or false. However, they are all false, because the world simply does not contain the sort of objective prescriptive properties that would be needed to make them true." This philosopher's view is correctly classified as:

  1. realist, because it holds that moral claims have truth values.
  2. anti-realist, because it denies that any positive moral claims are true. (correct answer)
  3. non-cognitivist, because it ultimately rejects the existence of moral properties.
  4. relativist, because it makes moral truth dependent on the existence of properties.
Explanation: The correct answer is B. The view described is J.L. Mackie's error theory. It is a form of anti-realism because it denies the existence of the moral reality that would be required for moral claims to be true. A is a classic error; while the view is cognitivist (moral claims have truth values), it is not realist because it claims all such propositions are false. Realism requires that at least some positive moral claims are true. C is incorrect because the view is explicitly cognitivist, which is the opposite of non-cognitivism. D misinterprets the position; it is absolutist in its denial of moral truth, not relativist.

Question 14

G. E. Moore's 'open-question argument' holds that for any proposed natural property N (e.g., 'pleasure'), the question 'Is N really good?' is always a meaningful, open question. This argument was primarily intended to challenge:

  1. all forms of moral anti-realism by proving that goodness is a real property.
  2. moral non-naturalism, which claims moral properties are sui generis.
  3. naturalistic moral realism, which seeks to identify moral properties with natural properties. (correct answer)
  4. error theory, by showing that claims about goodness can be meaningfully analyzed.
Explanation: The correct answer is C. The open-question argument is a classic argument against ethical naturalism, a form of moral realism that tries to define or identify 'goodness' with some natural property (like pleasure, survival value, social approval, etc.). Moore argued that since one can always sensibly ask if that natural property is itself good, 'good' must refer to a different, non-natural property. A is incorrect; Moore was a realist, but this argument doesn't prove realism, it just attacks one version of it. B is incorrect; Moore himself was a non-naturalist. D is incorrect as the argument's primary target is within the realist camp, not anti-realist error theory.

Question 15

Two philosophers are debating the morality of a new gene-editing technology. Philosopher A argues it is intrinsically wrong, while Philosopher B argues it is morally permissible. They appeal to principles, consequences, and intuitions, but fail to persuade one another. A moral realist would most likely interpret this persistent disagreement as:

  1. evidence that moral statements are merely expressions of emotion that lack objective truth value.
  2. an indication that the moral truth about the technology is relative to each philosopher's subjective framework.
  3. a complex epistemic challenge in discovering an objective moral fact that exists independently of their beliefs. (correct answer)
  4. proof that objective moral truths must not exist, as their existence would preclude such intractable disputes.
Explanation: The correct answer is C. Moral realism holds that objective moral facts exist, but it does not entail that these facts are easy to know or self-evident. A realist would view deep disagreement as a sign of the difficulty of moral inquiry (an epistemic problem), not as proof that there are no facts to be discovered (a metaphysical claim). A is the position of emotivism, a form of anti-realism. B describes subjectivism or relativism, another form of anti-realism. D draws a conclusion that a realist would reject; for a realist, the difficulty of discovery does not negate the existence of a fact, much like disagreements in physics don't negate the existence of physical laws.

Question 16

Consider the claim: "Genocide is morally evil." An error theorist, such as J.L. Mackie, would argue that this statement is:

  1. a true proposition, corresponding to a non-natural moral fact about the badness of genocide.
  2. a false proposition, because it purports to refer to an objective property of 'evil' which does not exist. (correct answer)
  3. neither true nor false, as it is merely an expression of strong disapproval toward genocide.
  4. a true proposition, provided that the speaker's culture universally condemns genocide.
Explanation: The correct answer is B. Error theory is a cognitivist but anti-realist view. It holds that moral statements are propositions (capable of being true or false) but that they are all systematically false. This is because they make a claim about the existence of objective values or properties (like 'evil') that, according to the error theorist, do not exist in the world. A describes moral non-naturalism, a form of realism. C describes non-cognitivism (like emotivism), which denies that moral statements are truth-apt. D describes cultural relativism.

Question 17

A society transitions from a system where slavery is morally accepted to one where it is condemned as a grave injustice. What is at stake in the debate between a moral realist and a cultural relativist in interpreting this change?

  1. Whether the abolition of slavery was economically beneficial for the society in the long term.
  2. Whether the society's new moral code is more internally consistent than its old one.
  3. Whether the change can be described as genuine moral progress toward a more correct moral view. (correct answer)
  4. Whether the majority of individuals in the society now personally believe that slavery is wrong.
Explanation: The correct answer is C. The concept of 'moral progress' is a key point of contention. A moral realist can say the society has progressed by better aligning its practices with objective moral truth (i.e., the truth that slavery is unjust). A cultural relativist, however, cannot ground this claim to progress. For the relativist, the old code was 'right' for that society then, and the new code is 'right' for this society now; there is no objective standard by which to judge one as better than the other, only as different. The other options describe considerations that are either empirical (A, D) or formal (B) and do not capture the core metaphysical disagreement about the status of the moral change itself.

Question 18

A political debate involves two speakers arguing about the justice of a wealth tax. Speaker A calls it 'a just policy for a fairer society.' Speaker B calls it 'unjust theft.' A non-cognitivist is most likely to interpret this exchange as:

  1. a factual disagreement about the economic consequences of the tax, which can be resolved by empirical data.
  2. a clash of non-rational attitudes and attempts to influence emotion, rather than a debate over objective truths. (correct answer)
  3. a genuine moral disagreement where one speaker is correct and the other is incorrect about the objective nature of justice.
  4. evidence that the concept of 'justice' is incoherent and all claims about it are systematically false.
Explanation: The correct answer is B. Non-cognitivism (which includes emotivism and prescriptivism) holds that moral statements do not express propositions but rather attitudes, emotions, or commands. From this perspective, the speakers are not debating a factual matter of what is 'just' or 'unjust' in an objective sense. Instead, they are expressing their conflicting feelings or attitudes about the policy and trying to persuade others to adopt their stance. A treats the disagreement as purely empirical, which the non-cognitivist would deny is the whole story for moral terms. C is the moral realist interpretation. D is the error theorist interpretation, which is cognitivist, unlike the non-cognitivist view.

Question 19

Imagine a possible world that has never contained any sentient beings or minds. There are only rocks, rivers, and stars. In this world, a meteor strikes a planet, causing a massive rockslide.

A moral realist who is not a divine command theorist would most likely hold that in this world, the statement 'The rockslide was morally bad' is:

  1. true, because moral properties like 'badness' can exist independently of any minds.
  2. false, because moral properties like 'badness' depend on the suffering or well-being of sentient creatures. (correct answer)
  3. meaningless, because moral language requires a community of speakers to have content.
  4. neither true nor false, because the concept of 'badness' is a human invention.
Explanation: The correct answer is B. This is a subtle question. While moral realism posits mind-independent moral facts, most forms of realism (especially naturalistic realism) tie moral properties like 'good' and 'bad' to states of the world affecting sentient beings (e.g., well-being, suffering, flourishing). The rockslide is a purely physical event with no impact on any sentient creature, so it has no moral status. Therefore, the statement is false. A represents an extreme Platonism that few realists would hold. C and D represent anti-realist positions. The question tests whether students understand that 'mind-independent' for a realist doesn't necessarily mean 'independent of any possible conscious experience.'

Question 20

An emotivist and an error theorist are observing a heated argument about abortion rights. Which of the following best captures a point of agreement between their meta-ethical views?

  1. There are no objective moral facts about abortion. (correct answer)
  2. The debaters' moral claims are not truth-apt.
  3. The debaters are making propositions that are systematically false.
  4. The debaters' moral language is fundamentally about commanding others.
Explanation: When you encounter meta-ethics questions comparing different theories, focus on what each theory says about the nature and status of moral claims themselves, not just their content. Both emotivism and error theory are anti-realist positions that deny objective moral facts exist in the world. Emotivists like A.J. Ayer argue that moral statements express emotions or attitudes rather than describing objective features of reality. Error theorists like J.L. Mackie argue that while moral statements attempt to describe objective facts, they systematically fail because no such facts exist. Despite their different explanations, both theories agree that there simply are no objective moral truths about abortion or any other moral issue. This makes A correct. B is wrong because error theorists believe moral claims are truth-apt (capable of being true or false) - they just think they're all false. Only emotivists deny truth-aptness entirely. C captures only the error theorist position. While error theorists do believe moral propositions are systematically false, emotivists don't view moral language as making propositions at all, so they can't be false. D mischaracterizes both theories. This describes prescriptivism (R.M. Hare's view), which treats moral language as fundamentally imperative. Emotivists focus on expressing attitudes, not commanding, while error theorists see moral language as attempting to describe (non-existent) facts. Remember: when comparing meta-ethical theories, look for their shared commitments about moral ontology (what exists) before getting caught up in their different explanations of moral language and psychology.
