Prompt 1: It seems that many moral realists simply assume morality or define morality circularly in their defenses of their moral systems. Please provide a list of quote among moral philosophers that highlight this problem, along with commentary.
Allan Gibbard is best read as a map of alignments, tensions, and priority.
The section turns on Allan Gibbard. Each piece is doing different work, and the page becomes thinner if the reader cannot say what is being identified, what is being tested, and what would change if one piece were removed.
The central claim is this: (It may be that the philosophers cited have adequate rebuttals to these accusations of circularity.).
The orienting landmarks here are It seems that many moral realists simply assume morality or define morality, Allan Gibbard, and It seems that many moral realists simply assume morality or define. Read them comparatively: what each part contributes, what depends on what, and where the tensions begin. If the reader cannot say what confusion would result from merging those anchors, the section still needs more work.
This first move lays down the vocabulary and stakes for Circularity in Moral Realism. It gives the reader something firm enough about it seems that many moral realists simply assume morality or define morality that the next prompt can press circularity without making the discussion restart.
At this stage, the gain is not memorizing the conclusion but learning to think with It seems that many moral realists simply, It seems that many moral realists simply, and Quotes and Commentary on Circular Definitions. A map is successful only when it shows dependence, priority, and tension rather than a decorative list of parts. The important caution is to keep moral feeling, moral language, and moral authority distinct even when they travel together in ordinary speech.
This reconstruction preserves the anti-realist pressure rather than translating it back into conventional moral realism. The curator's point is not merely that cultures disagree; it is that moral vocabulary may be doing emotional, social, and practical work without successfully referring to stance-independent moral facts. That view should not be softened into casual relativism; it is a sharper claim about what moral language is doing when it sounds as if it has discovered a property of the world.
The section is strongest when it keeps three pressures in the same field of view: semantic discipline, psychological motivation, and public practice. A moral sentence may express condemnation, coordinate behavior, protect vulnerable people, or dramatize a preference; the hard question is whether any of that adds up to an objective moral fact. The anti-realist line should therefore remain live and demanding, not tidied away because conventional ethics prefers a sturdier-looking floor.
“If I am asked, ‘What is good?’ my answer is that good is good, and that is the end of the matter.” Source: Principia Ethica (1903)
Moore’s definition of good as simply “good” is an example of circular reasoning. It doesn’t provide an external reference or criteria to understand what “good” is beyond its own definition, which is a common critique of moral realism.
“Moral goodness is best understood as the property which satisfies the role of ‘goodness’ in the folk-theoretical commitments of a society.” Source: How to Be a Moral Realist (1988)
Boyd’s definition implies that moral goodness is defined by societal standards, which can lead to circularity. This perspective suggests that what is morally good is what a society believes to be good, which can be self-referential and lacks an independent standard.
“The objective standpoint is, roughly, the standpoint of any rational being.” Source: The View from Nowhere (1986)
Nagel’s approach to moral objectivity ties it closely to rationality. This can be seen as circular if rationality is defined in moral terms, i.e., if rational beings are those who act morally, and moral actions are those performed by rational beings.
“We have reasons to do what is rational, and reasons to do what is moral. These two kinds of reasons are often the same.” Source: On What Matters (2011)
Parfit’s assertion that rational and moral reasons are often the same can be seen as circular if it doesn’t provide an independent criterion for morality outside of rationality, especially if rationality itself is morally defined.
“Moral facts are those which we would agree upon under conditions of ideal rational deliberation.” Source: The Moral Problem (1994)
Smith’s definition ties moral facts to ideal rational deliberation. This can lead to circularity if ideal rational deliberation presupposes moral understanding, thus not providing an independent grounding for moral facts.
“Moral properties are not objectively prescriptive, but rather reflect subjective attitudes and conventions.” Source: Ethics: Inventing Right and Wrong (1977)
While Mackie is an error theorist and not a realist, his critique points out that many moral realists’ definitions of moral properties rely on subjective attitudes, which can create a circular definition by conflating moral properties with widely held beliefs or conventions.
“To call something rational is to endorse it in the sense of normative endorsement.” Source: Wise Choices, Apt Feelings (1990)
Gibbard’s use of “normative endorsement” to define rationality can lead to circularity if normative endorsement is itself seen as a moral concept. Thus, rational actions are morally endorsed, and morally endorsed actions are rational, creating a circular relationship.
- Allan Gibbard: Many prominent moral philosophers, when defining moral concepts, often fall into circular reasoning by not providing independent criteria for these concepts.
- Semantic discipline: The page should ask whether it seems that many moral realists simply assume morality or define morality names a fact, an attitude, a recommendation, a prohibition, or a social warning.
- Anti-realist burden: Denying stance-independent moral facts does not by itself erase reasons, empathy, law, criticism, or the need to live with other humans.
- Realist objection: If moral language is reconstructed as emotional or social practice, the page should explain why some condemnations feel non-negotiable.
- Practical residue: The question becomes how to criticize cruelty, coercion, or hypocrisy without pretending the criticism has floated down from an objective moral realm.
Prompt 2: For each of those 7 quotes, provide a reductio syllogism highlighting their circularity.
G.E. Moore is best read as a map of alignments, tensions, and priority.
The section turns on G.E. Moore, Richard Boyd, and Thomas Nagel. Each piece is doing different work, and the page becomes thinner if the reader cannot say what is being identified, what is being tested, and what would change if one piece were removed.
The central claim is this: Therefore, “good” is defined without any independent standard (R).
The important discipline is to keep G.E. Moore distinct from Richard Boyd. They are not interchangeable bits of vocabulary; they direct the reader toward different judgments, objections, or next steps.
This middle step carries forward it seems that many moral realists simply assume morality or define morality. It shows what that earlier distinction changes before the page asks the reader to carry it any farther.
At this stage, the gain is not memorizing the conclusion but learning to think with Circularity, It seems that many moral realists simply, and Quotes and Commentary on Circular Definitions. A map is successful only when it shows dependence, priority, and tension rather than a decorative list of parts. The important caution is to keep moral feeling, moral language, and moral authority distinct even when they travel together in ordinary speech.
The added philosophical insight is that Circularity in Moral Realism often becomes confused when motivational force is mistaken for justificatory force. A claim can feel urgent, humane, or socially necessary while still needing an account of what makes it binding.
This reconstruction preserves the anti-realist pressure rather than translating it back into conventional moral realism. The curator's point is not merely that cultures disagree; it is that moral vocabulary may be doing emotional, social, and practical work without successfully referring to stance-independent moral facts.

“If I am asked, ‘What is good?’ my answer is that good is good, and that is the end of the matter.” Source: Principia Ethica (1903)
Defining “good” as “good” provides no external criteria (Q).
But defining a term should provide an independent standard (S).
Therefore, defining “good” as “good” is circular (T).
“Moral goodness is best understood as the property which satisfies the role of ‘goodness’ in the folk-theoretical commitments of a society.” Source: How to Be a Moral Realist (1988)
If moral goodness is what society believes to be good (P).
Society’s beliefs about goodness are based on their concept of moral goodness (Q).
But this provides no external criteria for moral goodness (S).
Therefore, Boyd’s definition is circular (T).
“The objective standpoint is, roughly, the standpoint of any rational being.” Source: The View from Nowhere (1986)
If the objective standpoint is the standpoint of any rational being (P).
A rational being is one who adopts the objective standpoint (Q).
But this provides no independent criteria for rationality (S).
Therefore, Nagel’s definition is circular (T).
“We have reasons to do what is rational, and reasons to do what is moral. These two kinds of reasons are often the same.” Source: On What Matters (2011)
If we have reasons to do what is rational and what is moral (P).
Rational actions are those we have moral reasons to perform (Q).
But this provides no independent criteria for rationality or morality (S).
- G.E. Moore: Therefore, “good” is defined without any independent standard (R).
- Richard Boyd: Therefore, moral goodness is what is believed to be moral goodness (R).
- Thomas Nagel: Therefore, the objective standpoint is the standpoint of one who adopts the objective standpoint (R).
- Derek Parfit: Therefore, rational actions are moral actions (R). The argument has to keep moral feeling, social practice, and justificatory force distinct so the conclusion is not smuggled into the vocabulary.
- Michael Smith: Therefore, moral facts are those agreed upon under an understanding of moral facts (R).
- John Mackie: Therefore, moral properties are those defined by subjective attitudes and conventions (R).
Prompt 3: Write a short essay for each of those quotes that highlights the logical flaws in the quote.
Essay 1: G.E. Moore is best read as a map of alignments, tensions, and priority.
The section turns on Essay 1: G.E. Moore, Essay 2: Richard Boyd, and Essay 3: Thomas Nagel. Each piece is doing different work, and the page becomes thinner if the reader cannot say what is being identified, what is being tested, and what would change if one piece were removed.
The central claim is this: The logical flaw here is that such a definition offers no explanatory power or clarity.
The important discipline is to keep Essay 1: G.E. Moore distinct from Essay 2: Richard Boyd. They are not interchangeable bits of vocabulary; they direct the reader toward different judgments, objections, or next steps.
By this point in the page, the earlier responses have already put circularity in motion. This final prompt gathers that pressure into a closing judgment rather than a disconnected last answer.
At this stage, the gain is not memorizing the conclusion but learning to think with It seems that many moral realists simply, Quotes and Commentary on Circular Definitions, and G.E. Moore. A map is successful only when it shows dependence, priority, and tension rather than a decorative list of parts.

“If I am asked, ‘What is good?’ my answer is that good is good, and that is the end of the matter.” Source: Principia Ethica (1903)
G.E. Moore’s statement, “If I am asked, ‘What is good?’ my answer is that good is good, and that is the end of the matter,” epitomizes the circular reasoning often critiqued in moral realism. This definition of “good” is inherently circular because it fails to provide any external or independent criteria for what constitutes “good.” By defining “good” solely in terms of itself, Moore does not elucidate what properties or characteristics make something good.
“Moral goodness is best understood as the property which satisfies the role of ‘goodness’ in the folk-theoretical commitments of a society.” Source: How to Be a Moral Realist (1988)
Richard Boyd’s definition of moral goodness as “the property which satisfies the role of ‘goodness’ in the folk-theoretical commitments of a society” introduces a form of circular reasoning that entangles moral concepts with societal beliefs. By tying moral goodness to societal commitments, Boyd’s definition implies that what a society deems good is, by definition, morally good. This approach does not offer an independent criterion for moral goodness, leading to logical circularity.
“The objective standpoint is, roughly, the standpoint of any rational being.” Source: The View from Nowhere (1986)
Thomas Nagel’s assertion that “the objective standpoint is, roughly, the standpoint of any rational being” introduces a circular definition that conflates rationality with objectivity in moral reasoning. According to Nagel, the objective standpoint is inherently tied to what a rational being would adopt, but this definition presupposes an understanding of both rationality and objectivity that lacks independent criteria.
“We have reasons to do what is rational, and reasons to do what is moral. These two kinds of reasons are often the same.” Source: On What Matters (2011)
Derek Parfit’s claim that “we have reasons to do what is rational, and reasons to do what is moral. These two kinds of reasons are often the same” introduces a potential circularity by conflating rational and moral reasons. This assertion implies that what is rationally justified is also morally justified, but it does not provide an independent criterion for either rationality or morality.
“Moral facts are those which we would agree upon under conditions of ideal rational deliberation.” Source: The Moral Problem (1994)
Michael Smith’s definition that “moral facts are those which we would agree upon under conditions of ideal rational deliberation” introduces a form of circular reasoning by tying moral facts to the process of rational deliberation. This definition presupposes an understanding of both moral facts and ideal rational deliberation without providing independent criteria for either.
“Moral properties are not objectively prescriptive, but rather reflect subjective attitudes and conventions.” Source: Ethics: Inventing Right and Wrong (1977)
John Mackie’s assertion that “moral properties are not objectively prescriptive, but rather reflect subjective attitudes and conventions” critiques moral realism by highlighting the subjectivity inherent in moral properties. While Mackie himself is an error theorist, his critique points out the circularity in many moral realists’ definitions.
“To call something rational is to endorse it in the sense of normative endorsement.” Source: Wise Choices, Apt Feelings (1990)
Allan Gibbard’s statement that “to call something rational is to endorse it in the sense of normative endorsement” introduces a form of circular reasoning by conflating rationality with normative endorsement. This definition presupposes that rational actions are those normatively endorsed, but it does not provide independent criteria for either rationality or normative endorsement.
What is the main critique of G.E. Moore’s definition of “good”?
What issue arises from Derek Parfit’s assertion about rational and moral reasons?
What is the main point of the critique of ethical realism on 1000-Word Philosophy?
How does the analysis of Shafer-Landau’s moral realism highlight circularity?
- Essay 1: G.E. Moore: The logical flaw here is that such a definition offers no explanatory power or clarity.
- Essay 2: Richard Boyd: The primary flaw in Boyd’s definition is that it relativizes moral goodness to societal norms without providing an external standard.
- Essay 3: Thomas Nagel: The logical flaw in Nagel’s definition is that it does not clarify what makes a standpoint rational or objective without referencing each other.
- Essay 4: Derek Parfit: The logical flaw in Parfit’s argument lies in the lack of a clear, independent definition for rationality and morality.
- Essay 5: Michael Smith: The logical flaw in Smith’s argument is that it does not explain what constitutes ideal rational deliberation without referencing moral facts.
- Essay 6: John Mackie: The logical flaw in Mackie’s argument, from a moral realist perspective, is that it relativizes moral properties to subjective attitudes and conventions.
The through-line is It seems that many moral realists simply assume morality or define, Quotes and Commentary on Circular Definitions in Moral Realism, G.E. Moore, and Richard Boyd.
The best route is to keep three questions apart: what people value, what a moral sentence means, and what could justify a demand on another person.
The live pressure includes moral realism, moral non-realism, divine command theory, human rights language, and the risk of smuggling an ought into premises that only describe what is.
The anchors here are It seems that many moral realists simply assume morality or define, Quotes and Commentary on Circular Definitions in Moral Realism, and G.E. Moore. Together they tell the reader what is being claimed, where it is tested, and what would change if the distinction holds.
