Self-Evident Morality?

The concept of self-evidence in moral philosophy suggests that certain moral propositions are so inherently true that they require no further justification.
Moral propositions lack the definitive proof mechanisms that characterize mathematical truths.
The existence of contradictory self-evident claims undermines the notion of self-evidence because two opposing propositions cannot both be true.
Relying on self-evidence can lead to dogmatism, where one refuses to consider alternative viewpoints.
Moral truths cannot be proven through the same definitive methods, as they are influenced by subjective factors and lack universal acceptance.

Many moralists invoke the “self-evident” nature of morality to substantiate their diverse notions of morality. Rigorously critique the intrinsic weaknesses in this argument.

Example: And so I came to the conclusion that there is a reasonable case for saying that there are objective moral truths and this is not just a matter of our attitudes or of our preferences universalized, but there’s something stronger going on and it’s, in some ways, more like the objectivity of mathematical truths or perhaps of logical truths. It’s not an empirical thing. This is not something you can describe that comes in the world, the natural world of our sense that you can find or prove empirically. It’s rather something that is rationally self-evident, I guess, to people who reflect on it properly and think about it carefully. So that’s how I gradually made the move towards objectivist metaethic. — Peter Singer

The appeal to the “self-evident” nature of morality is a common strategy among moralists to validate their moral propositions. However, relying on self-evidence as a foundation for moral truths has intrinsic weaknesses that undermine its effectiveness as a robust argument. This critique will explore these weaknesses through rigorous analysis, syllogisms, and symbolic logic.

Subjectivity of Self-Evidence

What is deemed self-evident is often subject to personal intuition, cultural background, or societal norms. This subjectivity raises the question of whether self-evidence can serve as an objective foundation for morality.

Syllogism:

Premise 1: If a proposition is self-evident, then it is universally recognized as true.
Premise 2: Moral propositions are not universally recognized as true.
Conclusion: Therefore, moral propositions are not self-evident.

Symbolic Logic:

Let:

$S(p)$ = “Proposition $p$ is self-evident”
$U(p)$ = “Proposition $p$ is universally recognized as true”

We have:

$\forall p \ (S(p) \rightarrow U(p))$
$\exists p \ (M(p) \land \neg U(p))$
Therefore, $\exists p \ (M(p) \land \neg S(p))$

Where $M(p)$ denotes that $p$ is a moral proposition.

Circular Reasoning

Asserting that a moral proposition is true because it is self-evident often leads to circular reasoning. The argument assumes the truth of the proposition within its premise without external validation.

Syllogism:

Premise: Moral proposition $p$ is true because it is self-evident.
But why is $p$ self-evident? Because it is true.
Conclusion: Therefore, $p$ is true because it is true.

Symbolic Logic:

Let:

$T(p)$ = “Proposition $p$ is true”
$S(p)$ = “Proposition $p$ is self-evident”

We observe:

$T(p) \leftrightarrow S(p)$
$S(p) \leftrightarrow T(p)$
This forms a tautology without independent support.

Disagreement in Moral Intuitions

The existence of diverse and conflicting moral intuitions across different cultures and individuals suggests that moral truths are not self-evident.

Syllogism:

Premise 1: If moral truths are self-evident, then all rational agents should recognize them.
Premise 2: Rational agents often disagree on moral issues.
Conclusion: Therefore, moral truths are not self-evident.

Symbolic Logic:

Let:

$R(a)$ = “Agent $a$ is rational”
$S(p)$ = “Proposition $p$ is self-evident”
$K(a, p)$ = “Agent $a$ knows proposition $p$ “

We have:

$\forall a \ (R(a) \rightarrow (S(p) \rightarrow K(a, p)))$
$\exists a, b \ (R(a) \land R(b) \land \neg (K(a, p) \leftrightarrow K(b, p)))$
Therefore, $\neg \forall a \ (R(a) \rightarrow K(a, p))$
Hence, $\neg S(p)$

Inapplicability of Mathematical Objectivity

Comparing moral truths to mathematical truths is flawed because mathematical propositions can be proven through logical deduction, whereas moral propositions lack such definitive proof mechanisms.

Syllogism:

Premise 1: Mathematical truths are self-evident because they can be logically proven.
Premise 2: Moral propositions cannot be logically proven in the same way.
Conclusion: Therefore, moral propositions are not self-evident like mathematical truths.

Symbolic Logic:

Let:

$P(p)$ = “Proposition $p$ can be logically proven”
$S(p)$ = “Proposition $p$ is self-evident”
$M(p)$ = “Proposition $p$ is a moral proposition”
$T(p)$ = “Proposition $p$ is a mathematical truth”

We have:

$\forall p \ (T(p) \rightarrow (P(p) \land S(p)))$
$\forall p \ (M(p) \rightarrow \neg P(p))$
Therefore, $\forall p \ (M(p) \rightarrow \neg S(p))$

Contradictory Self-Evident Claims

Different moral systems often present contradictory propositions as self-evident, leading to logical inconsistencies.

Syllogism:

Premise 1: Proposition $p$ is self-evident and states that action $A$ is morally obligatory.
Premise 2: Proposition $q$ is self-evident and states that action $A$ is not morally obligatory.
Conclusion: Contradiction arises, so both propositions cannot be self-evident truths.

Symbolic Logic:

Let:

$S(p)$ = “Proposition $p$ is self-evident”
$S(q)$ = “Proposition $q$ is self-evident”
$p: O(A)$ = “Action $A$ is obligatory”
$q: \neg O(A)$ = “Action $A$ is not obligatory”

We have:

$S(p) \land p$
$S(q) \land q$
Since $p$ and $q$ are contradictory: $p \leftrightarrow \neg q$
Therefore, the simultaneous truth of $S(p)$ and $S(q)$ leads to a contradiction.

Conclusion

The invocation of self-evidence in moral arguments is fraught with intrinsic weaknesses such as subjectivity, circular reasoning, disagreement among rational agents, and logical inconsistencies. These issues highlight that self-evidence is an insufficient foundation for establishing objective moral truths. A more robust approach would require independent validation of moral propositions beyond mere appeals to self-evidence.

The Subjectivity of Self-Evidence in Moral Arguments

Introduction

The concept of self-evidence has long been invoked by moralists as a foundational pillar to substantiate diverse moral propositions. The assertion is that certain moral truths are so apparent that they require no further justification beyond their self-evident nature. However, this reliance on self-evidence is fraught with intrinsic weaknesses, primarily due to its inherent subjectivity. This essay critically examines the subjectivity of self-evidence in moral arguments, highlighting how personal intuitions, cultural backgrounds, and societal norms influence what individuals perceive as self-evident. Through rigorous analysis, syllogisms, and symbolic logic, we will demonstrate that self-evidence cannot serve as an objective foundation for morality.

The Nature of Self-Evidence

Self-evidence refers to the quality of a proposition that is known to be true by understanding its meaning without the need for external proof. In mathematics and logic, certain axioms are accepted as self-evident truths because they are universally recognized and form the basis for further reasoning. However, when applied to morality, the concept becomes problematic due to the lack of universal agreement on moral propositions.

The Problem of Subjectivity

What one individual or culture deems self-evident may not be perceived the same way by another. Moral intuitions are deeply influenced by various factors, including upbringing, religious beliefs, and societal values. This subjectivity leads to a divergence in moral judgments, making it untenable to claim that any moral proposition is self-evident in an objective sense.

Analysis through Syllogisms and Symbolic Logic

To rigorously critique the subjectivity of self-evidence in moral arguments, we will employ syllogistic reasoning and symbolic logic.

Syllogism

Premise 1: If a proposition is self-evident, then it is universally recognized as true.
Premise 2: Moral propositions are not universally recognized as true.
Conclusion: Therefore, moral propositions are not self-evident.

This syllogism highlights the essential criterion for self-evidence—universal recognition—which moral propositions fail to meet due to their subjective nature.

Symbolic Logic

Let us define the following:

$S(p)$ : “Proposition $p$ is self-evident.”
$U(p)$ : “Proposition $p$ is universally recognized as true.”
$M(p)$ : “Proposition $p$ is a moral proposition.”

We can formalize the argument as:

- For all propositions $p$ , if $p$ is self-evident, then $p$ is universally recognized as true.
- There exists a proposition $p$ such that $p$ is a moral proposition and $p$ is not universally recognized as true.
Therefore,
- Therefore, there exists a moral proposition $p$ that is not self-evident.

This logical formulation demonstrates that since moral propositions lack universal recognition, they cannot be considered self-evident.

Cultural and Individual Variability

Influence of Culture

Cultural diversity leads to different moral codes and values. For instance, practices considered morally acceptable in one culture may be deemed reprehensible in another. This cultural variability undermines the claim of self-evidence in moral propositions.

Example: Consider the moral acceptability of arranged marriages. In some cultures, arranged marriages are viewed as a self-evident good that promotes familial harmony and social stability. In contrast, other cultures perceive them as self-evidently oppressive and a violation of individual autonomy.

Influence of Personal Intuition

Individual experiences and psychological factors shape personal moral intuitions. Two rational individuals may arrive at opposing moral conclusions based on their unique perspectives, further illustrating the subjectivity involved.

Example: A person who has experienced the adverse effects of capital punishment might find it self-evident that it is immoral, while another might find it self-evident that it serves as a just deterrent for heinous crimes.

The Illusion of Objectivity

Proponents of self-evident moral truths often assert that certain moral principles are as objective as mathematical axioms. However, mathematical axioms are abstract constructs that do not vary between cultures or individuals, whereas moral principles do not share this universality.

Comparing Mathematical and Moral Self-Evidence

In mathematics:

Axioms are accepted universally because they are definitions or evident truths that underpin the logical structure of the system.
The acceptance of axioms is not influenced by cultural or personal factors.

In morality:

Moral propositions lack such universal acceptance.
Their supposed self-evidence is often a reflection of predominant cultural or personal beliefs rather than objective truths.

The Challenge of Moral Disagreements

Persistent moral disagreements among rational agents indicate that moral propositions are not self-evident. If they were, such disagreements would either not occur or would be resolvable through rational discourse alone.

Symbolic Logic of Disagreement

Let:

$R(a)$ : “Agent $a$ is rational.”
$K(a, p)$ : “Agent $a$ knows proposition $p$ .”

We can express the issue as:

- If $p$ is self-evident, then all rational agents $a$ know $p$ .
- There exist rational agents $a$ and $b$ such that one knows $p$ and the other does not.
Therefore,
- Not all rational agents know $p$ .
Hence,
- Therefore, $p$ is not self-evident.

This logic underscores that the existence of rational disagreement over moral propositions negates their self-evidence.

Implications for Moral Philosophy

The Need for External Justification

Given the subjectivity of self-evidence in moral propositions, moral philosophers must seek external justifications for moral claims. This involves:

Providing empirical evidence where possible.
Employing coherent ethical theories that can be critically examined.
Engaging in cross-cultural dialogues to understand diverse moral perspectives.

Avoiding Dogmatism

Relying on self-evidence can lead to dogmatism, where individuals or groups refuse to consider alternative viewpoints due to the belief that their moral stance is unquestionably true. Recognizing the subjectivity involved encourages openness and critical examination of one’s moral beliefs.

Conclusion

The invocation of self-evidence in moral arguments is undermined by its inherent subjectivity. Moral propositions lack the universal recognition necessary for self-evidence due to the significant influence of cultural, societal, and personal factors on moral intuitions. Logical analysis through syllogisms and symbolic logic reveals that self-evidence cannot serve as an objective foundation for morality. Moral philosophy must, therefore, rely on external justifications and rational discourse to establish moral truths, fostering a more inclusive and critically engaged ethical landscape.

The Circular Reasoning in Appeals to Self-Evident Morality

Introduction

The notion of self-evidence is frequently employed by moralists to assert the truth of certain moral propositions without requiring further justification. This appeal suggests that some moral truths are so inherently obvious that they stand beyond doubt or debate. However, relying on self-evidence in moral arguments often leads to circular reasoning, wherein the conclusion is implicitly or explicitly assumed in the premises. This essay critically examines the intrinsic weakness of circular reasoning in appeals to self-evident morality. Through detailed analysis, syllogisms, and symbolic logic, we will demonstrate how such arguments lack independent support and fail to provide a robust foundation for moral claims.

Understanding Circular Reasoning

Circular reasoning, or begging the question (petitio principii), occurs when an argument’s conclusion is assumed within its premises, offering no substantive proof outside of the assertion itself. This logical fallacy undermines the validity of an argument because it does not provide external evidence or reasoning to support the conclusion.

Example of Circular Reasoning in Everyday Context

A classic example of circular reasoning is:

“I am trustworthy because I say I am trustworthy.”

Here, the speaker’s trustworthiness is assumed based on their own assertion, offering no independent verification.

Circular Reasoning in Moral Arguments

When moralists claim that a proposition is true because it is self-evident, they often engage in circular reasoning. The argument typically unfolds as follows:

Premise: Moral proposition $p$ is true because it is self-evident.
Question: Why is $p$ self-evident?
Response: Because it is true.
Conclusion: Therefore, $p$ is true because it is true.

This circularity fails to provide an independent justification for the moral proposition, rendering the argument logically flawed.

Formalizing the Circular Reasoning

To critically analyze this circularity, we can employ syllogisms and symbolic logic.

Syllogism

Premise 1: Moral proposition $p$ is self-evident.
Premise 2: If a proposition is self-evident, then it is true.
Conclusion: Therefore, moral proposition $p$ is true because it is self-evident.

However, when we inquire why $p$ is considered self-evident, the justification often circles back to its supposed truth, completing the circular loop.

Symbolic Logic

Let us define:

$T(p)$ : “Proposition $p$ is true.”
$S(p)$ : “Proposition $p$ is self-evident.”

We can express the argument as:

- If $p$ is self-evident, then $p$ is true.
- If $p$ is true (in the context of self-evident propositions), then $p$ is self-evident.

This forms a biconditional relationship:

$T(p) \leftrightarrow S(p)$

The proposition’s truth and its self-evidence are defined in terms of each other, with no external grounding, thus constituting circular reasoning.

The Logical Flaws of Circular Reasoning

Lack of Independent Support

An argument that relies on circular reasoning provides no independent evidence or rationale to substantiate its conclusion. In moral discourse, this means that asserting a moral proposition as self-evident does not advance understanding or persuade skeptics, as it merely restates the proposition in different terms.

Example

Assertion: “Honesty is morally obligatory because it is self-evident.”
Challenge: “Why is it self-evident?”
Response: “Because honesty is morally obligatory.”

This exchange highlights the lack of independent justification for why honesty should be considered morally obligatory.

Failure to Persuade Skeptics

Circular arguments are ineffective in persuading those who do not already accept the proposition. Since the argument assumes agreement on the very point in question, it cannot bridge differences in moral perspectives.

Illustration

A person skeptical about the moral obligation of honesty will not be convinced by an argument that presupposes the obligation’s truth.
Without external reasons or evidence, the skeptic remains unconvinced.

The Necessity of External Justification

For a moral argument to be compelling, it must provide reasons that are independent of the conclusion. This involves:

Empirical Evidence: Demonstrating the consequences of moral actions in the real world.
Logical Reasoning: Building arguments based on widely accepted premises.
Ethical Theories: Grounding propositions in established moral philosophies.

Avoiding Circularity

To avoid circular reasoning, moralists should:

Define Terms Clearly: Ensure that the premises do not contain implicit assumptions of the conclusion.
Provide Independent Premises: Use evidence or reasoning not contingent on the truth of the conclusion.
Address Counterarguments: Engage with opposing views to strengthen the argument’s validity.

Analysis through Symbolic Logic

To further elucidate the circularity issue, let’s construct a formal logical representation.

Definitions

Let:

$M(p)$ : “Proposition $p$ is a moral proposition.”
$E(p)$ : “Proposition $p$ is established by evidence or reasoning.”
$S(p)$ : “Proposition $p$ is self-evident.”
$T(p)$ : “Proposition $p$ is true.”

Argument Structure

Assumption:
- If $p$ is self-evident, then $p$ is true.
Question: Why is $p$ self-evident?
Response:
- If $p$ is true, then $p$ is self-evident.

This forms a circular dependency:

$S(p) \leftrightarrow T(p)$

There is no introduction of $E(p)$ , meaning that no independent evidence or reasoning is provided.

Implications

The truth of $p$ depends on its self-evidence, which in turn depends on its truth.
This circularity fails to satisfy the requirement for a valid logical argument, which must have premises that are independent of the conclusion.

The Difference Between Analytic and Synthetic Propositions

Understanding the distinction between analytic and synthetic propositions can further clarify the issue.

Analytic Propositions

Definition: Statements that are true by virtue of their meaning, such as “All bachelors are unmarried men.”
Characteristic: Their truth is self-contained and does not rely on external facts.

Synthetic Propositions

Definition: Statements whose truth depends on how the world is, such as “The cat is on the mat.”
Characteristic: They require empirical verification.

Application to Moral Propositions

Moral propositions are synthetic; their truth is not self-evident in the analytic sense.
Claiming a moral proposition is self-evident attempts to treat it as analytic, which it is not.
Therefore, asserting self-evidence in moral propositions leads to circular reasoning because it conflates analytic certainty with synthetic inquiry.

The Role of Assumptions in Logical Arguments

All logical arguments begin with assumptions or premises. However, for an argument to be sound, these premises must be acceptable to all parties involved or supported by independent evidence.

Acceptable Premises

Common Ground: Premises should be based on shared understandings or facts.
Independent Verification: Premises should be verifiable without assuming the conclusion.

Circular Premises

Premises that assume the conclusion do not provide a path to new knowledge or understanding.
In moral arguments, assuming the self-evidence of a proposition is equivalent to assuming its truth without proof.

Addressing Potential Counterarguments

Claim: Self-Evidence Is a Valid Foundation

Some may argue that self-evidence is a valid foundation for certain truths, including moral ones.

Response

While self-evidence may be acceptable for certain axiomatic truths in mathematics or logic, moral propositions lack the universal agreement necessary for self-evidence.
The subjective nature of morality means that what is self-evident to one person may not be to another.

Claim: Moral Intuitions Provide Self-Evidence

Another argument is that moral intuitions are innate and provide self-evident truths.

Response

Moral intuitions vary widely among individuals and cultures.
Relying on intuition without external justification leads back to circular reasoning.

The Importance of Non-Circular Justification in Ethics

Enhancing Persuasion

Providing independent reasons for moral propositions makes arguments more persuasive to a broader audience.
It allows for meaningful dialogue and potential consensus.

Strengthening Moral Theories

Avoiding circular reasoning contributes to the development of robust moral theories that can withstand critical scrutiny.
It encourages the use of interdisciplinary approaches, incorporating insights from psychology, sociology, and other fields.

Conclusion

The reliance on self-evidence in moral arguments often results in circular reasoning, where the truth of a proposition is assumed within its premises without independent support. This logical flaw undermines the validity of moral claims and fails to provide persuasive arguments to those who do not already accept the proposition. By recognizing and avoiding circular reasoning, moralists and philosophers can develop more compelling and robust ethical arguments that stand up to critical examination. Ultimately, grounding moral propositions in independent evidence and reasoning is essential for advancing moral discourse and fostering mutual understanding.

Disagreement in Moral Intuitions and the Question of Self-Evidence in Morality

Introduction

The claim that certain moral truths are self-evident has been a cornerstone in various moral philosophies. Proponents argue that some moral propositions are so fundamental that they require no further justification beyond their immediate recognition by rational agents. However, the persistent and widespread disagreement in moral intuitions among individuals and cultures challenges this assertion. This essay critically examines the argument that moral truths are not self-evident due to the observable disagreements in moral intuitions. Through detailed analysis, syllogisms, and symbolic logic, we will explore how these disagreements undermine the notion of self-evident morality.

The Nature of Moral Intuitions

Moral intuitions refer to the immediate, instinctive judgments that individuals make about the rightness or wrongness of actions without conscious deliberation. These intuitions are influenced by a myriad of factors, including cultural norms, personal experiences, upbringing, and innate psychological tendencies. While some moral intuitions may seem universally shared, closer examination reveals significant variations across different contexts.

Cultural and Individual Diversity in Moral Judgments

Cultural Variations

Different cultures have diverse moral codes that reflect their unique histories, religions, and social structures. Practices deemed morally acceptable in one culture may be considered immoral in another.

Example: The practice of polygamy is morally accepted in some societies but considered unethical in others.
Example: Attitudes toward euthanasia vary significantly between cultures, with some viewing it as compassionate and others as morally impermissible.

Individual Differences

Even within the same culture, individuals may hold divergent moral intuitions based on personal experiences or psychological factors.

Example: Two individuals exposed to the same cultural environment may disagree on the morality of capital punishment due to personal beliefs or emotional responses.

Logical Analysis of Disagreement in Moral Intuitions

The existence of disagreements among rational agents about moral propositions suggests that these propositions are not self-evident. If moral truths were self-evident, all rational agents would recognize them without dispute.

Syllogistic Analysis

Premise 1: If moral truths are self-evident, then all rational agents should recognize them as true.
Premise 2: Rational agents often disagree on moral issues.
Conclusion: Therefore, moral truths are not self-evident.

This syllogism demonstrates that the lack of universal agreement among rational individuals contradicts the notion of self-evident moral truths.

Symbolic Logic

Let us define the following symbols:

$R(a)$ : “Agent $a$ is rational.”
$S(p)$ : “Proposition $p$ is self-evident.”
$K(a, p)$ : “Agent $a$ knows proposition $p$ .”
$M(p)$ : “Proposition $p$ is a moral proposition.”

We can formalize the argument as follows:

Definition of Self-Evident Moral Truths:

$\forall a \ [R(a) \rightarrow (S(p) \rightarrow K(a, p))]$

For all agents $a$ , if $a$ is rational, then if $p$ is self-evident, $a$ knows $p$ .

Existence of Disagreement:

$\exists a, b \ [R(a) \land R(b) \land K(a, p) \land \neg K(b, p)]$

There exist rational agents $a$ and $b$ such that $a$ knows $p$ , and $b$ does not know $p$ .

Contradiction of Universal Recognition:

From (1) and (2), we derive:

$\neg \forall a \ [R(a) \rightarrow K(a, p)]$

Not all rational agents know $p$ .

Conclusion:

Therefore, $S(p)$ cannot be true:

$\neg S(p)$

Proposition $p$ is not self-evident.

This logical structure shows that the disagreement among rational agents over moral propositions negates their supposed self-evidence.

Implications for the Concept of Self-Evidence in Morality

The Requirement of Universal Recognition

For a proposition to be self-evident, it must be universally recognized by all rational agents upon understanding its meaning. The observable disagreements in moral intuitions indicate that moral propositions do not meet this criterion.

Argument: If a moral truth were self-evident, then no rational agent would deny it upon proper reflection.
Observation: Rational agents do, in fact, disagree on moral propositions even after careful consideration.

Challenges to Objectivity

The variability in moral intuitions suggests that moral judgments are influenced by subjective factors, undermining claims of objective, self-evident moral truths.

Subjectivity: Moral intuitions are shaped by individual experiences and cultural contexts.
Relativism: This leads to moral relativism, where moral truths are not absolute but relative to societies or individuals.

The Challenge of Moral Relativism

Moral relativism posits that there are no objective moral truths applicable to all people at all times. The disagreement in moral intuitions supports this view, challenging the existence of self-evident moral propositions.

Ethical Implications

Tolerance: Encourages tolerance of differing moral perspectives.
Conflict: May lead to difficulties in resolving moral disputes due to the lack of common ground.

Philosophical Responses

Moral Universalism: Attempts to establish universal moral principles that transcend cultural and individual differences.
Constructivism: Suggests that moral truths are constructed through social agreements rather than discovered as self-evident truths.

The Need for Objective Justification in Moral Philosophy

Given the disagreements in moral intuitions, moral philosophers must seek objective justifications for moral propositions beyond appeals to self-evidence.

Rational Discourse

Engaging in rational discourse allows for the examination of moral propositions through logical arguments and evidence.

Example: Debating the morality of an action based on its consequences, rights involved, or adherence to universal principles.

Ethical Theories

Utilizing established ethical theories provides frameworks for evaluating moral propositions.

Utilitarianism: Assesses morality based on the greatest good for the greatest number.
Deontology: Focuses on duties and adherence to moral rules.
Virtue Ethics: Emphasizes the character of the moral agent.

Conclusion

The persistent disagreement in moral intuitions among rational agents undermines the claim that moral truths are self-evident. The lack of universal recognition of moral propositions indicates that they are not immediately known to all upon understanding their meaning. This challenges the validity of appeals to self-evidence in moral arguments and highlights the need for objective justification through rational discourse and ethical theories. Recognizing the subjectivity inherent in moral intuitions encourages a more critical and open-minded approach to moral philosophy, fostering constructive dialogue and deeper understanding.

Inapplicability of Mathematical Objectivity in Moral Propositions

Introduction

The quest for objective moral truths has led some moralists to draw parallels between morality and mathematics, suggesting that moral propositions are as self-evident and objectively true as mathematical axioms. Peter Singer, for instance, posits that moral truths are “more like the objectivity of mathematical truths or perhaps of logical truths.” This comparison aims to elevate moral propositions to the realm of undeniable certainty. However, this essay argues that the analogy between mathematical objectivity and moral propositions is fundamentally flawed. By examining the nature of mathematical truths and contrasting them with moral assertions, we will demonstrate that moral propositions lack the definitive proof mechanisms and universal acceptance inherent in mathematics. Through syllogisms and symbolic logic, we will elucidate why the inapplicability of mathematical objectivity undermines the argument for self-evident moral truths.

The Nature of Mathematical Objectivity

Mathematical objectivity is characterized by the universality and necessity of mathematical truths. These truths are derived from axioms and proven through logical deduction within a formal system.

Characteristics of Mathematical Truths

Axiomatic Foundations: Mathematics is built upon axioms—self-evident truths accepted without proof—that serve as the starting point for further reasoning.
Logical Deduction: Theorems are proven through rigorous logical processes, ensuring that conclusions follow necessarily from premises.
Universal Acceptance: Mathematical propositions, once proven, are universally recognized as true regardless of cultural or subjective differences.
Abstract Nature: Mathematics deals with abstract concepts that are not contingent upon empirical observations of the physical world.

Example

Pythagorean Theorem: Given in a right-angled triangle, the relationship $a^2 + b^2 = c^2$ holds universally and can be proven through various logical methods.

Differences Between Mathematics and Morality

While mathematics operates within a closed logical system with clear definitions and rules, morality is a complex human construct influenced by a multitude of factors.

Characteristics of Moral Propositions

Cultural Influence: Moral values vary significantly across different societies and historical periods.
Subjectivity: Moral judgments are often based on personal beliefs, emotions, and experiences.
Lack of Formal Proof: Moral propositions cannot be proven in the same way mathematical theorems are; they lack universally accepted axioms and deduction methods.
Empirical Contingency: Morality is connected to human experiences and social contexts, making it contingent rather than necessary.

Contrasting Examples

Mathematical Proposition: “The sum of the interior angles of a triangle equals 180 degrees in Euclidean geometry” is universally accepted and proven.
Moral Proposition: “Stealing is wrong” may be accepted in many societies but is subject to exceptions, interpretations, and cultural variations.

The Lack of Logical Proofs in Morality

Moral propositions lack the definitive proof mechanisms that characterize mathematical truths. There are several reasons for this discrepancy.

Absence of Universal Axioms

No Common Starting Point: Unlike mathematics, morality does not have universally accepted axioms from which all moral truths can be derived.
Diverse Ethical Theories: Different ethical frameworks (e.g., utilitarianism, deontology, virtue ethics) propose varying foundational principles.

Inability to Use Deductive Reasoning Exclusively

Dependence on Empirical Facts: Moral reasoning often involves empirical information about human well-being, consequences, and societal norms.
Open-Ended Debates: Moral discussions frequently lead to ongoing debates rather than conclusive proofs.

Syllogistic and Symbolic Logic Analysis

To formalize the argument, we can construct a syllogism and represent it using symbolic logic.

Syllogism

Premise 1: Mathematical truths are self-evident because they can be logically proven from universally accepted axioms.
Premise 2: Moral propositions cannot be logically proven from universally accepted axioms.
Conclusion: Therefore, moral propositions are not self-evident like mathematical truths.

Symbolic Logic

Let us define the following symbols:

$P(p)$ : “Proposition $p$ can be logically proven.”
$S(p)$ : “Proposition $p$ is self-evident.”
$M(p)$ : “Proposition $p$ is a moral proposition.”
$T(p)$ : “Proposition $p$ is a mathematical truth.”

We can express the argument as:

For Mathematical Truths:

$\forall p \ [T(p) \rightarrow (P(p) \land S(p))]$

For all propositions $p$ , if $p$ is a mathematical truth, then $p$ can be logically proven and is self-evident.

For Moral Propositions:

$\forall p \ [M(p) \rightarrow \neg P(p)]$

For all propositions $p$ , if $p$ is a moral proposition, then $p$ cannot be logically proven.

Conclusion for Moral Propositions:

From (2):

$\forall p \ [M(p) \rightarrow \neg S(p)]$

Therefore, if $p$ is a moral proposition, then $p$ is not self-evident.

This logical structure demonstrates that moral propositions lack the qualities that make mathematical truths self-evident, thereby making the analogy inapplicable.

Implications for Moral Objectivity

The inability to apply mathematical objectivity to moral propositions has significant implications for claims of self-evident moral truths.

Challenges to Objective Morality

Subjectivity of Moral Judgments: Without universal axioms and proof methods, moral judgments remain subjective and open to interpretation.
Cultural Relativism: The diversity of moral codes across cultures suggests that morality is not objective in the same way mathematics is.

Need for Alternative Foundations

Empirical Ethics: Some philosophers advocate for grounding morality in empirical observations about human flourishing and societal well-being.
Constructivist Approaches: Others propose that moral principles are constructed through social contracts and collective agreements.

Some may argue that basic moral intuitions serve as axioms similar to those in mathematics.

Rebuttal: Unlike mathematical axioms, moral intuitions are not universally shared or accepted. They vary widely between individuals and cultures, undermining their suitability as foundational axioms.

Counterargument: Moral Laws as Universal Truths

Others might claim that certain moral laws are universally recognized, supporting their objectivity.

Rebuttal: While there may be broad agreements on some moral principles, exceptions and disagreements persist, indicating that these laws are not universally binding in the same way mathematical truths are.

Conclusion

The analogy between mathematical objectivity and moral propositions fails upon close examination. Mathematical truths are self-evident due to their derivation from universally accepted axioms and logical proofs, characteristics that moral propositions lack. Moral truths cannot be established through the same definitive methods, as they are influenced by subjective factors and lack universal acceptance. Therefore, appealing to mathematical objectivity to substantiate self-evident moral truths is intrinsically weak and inapplicable. A more robust approach to morality requires acknowledging its unique nature and seeking foundations appropriate to ethical inquiry.

Contradictory Self-Evident Claims and the Problem of Logical Inconsistency in Morality

Introduction

The notion of self-evidence in moral philosophy suggests that certain moral propositions are so inherently true that they require no further justification. Moralists often appeal to self-evidence to assert the indisputable nature of their moral claims. However, a critical issue arises when different moral systems or individuals present contradictory propositions, each purportedly self-evident. This leads to logical inconsistencies that undermine the reliability of self-evidence as a foundation for moral truths. This essay explores the intrinsic weakness of appealing to self-evidence in morality due to the existence of contradictory self-evident claims. Through syllogisms and symbolic logic, we will demonstrate how such contradictions challenge the validity of self-evidence in moral arguments.

The Concept of Self-Evidence in Morality

Self-evidence in moral philosophy refers to propositions that are immediately known to be true upon understanding their meaning, without the need for further proof. These propositions are considered foundational and are thought to provide a secure basis for moral reasoning.

Characteristics of Self-Evident Moral Propositions

Immediate Recognition: They are known to be true intuitively.
Universal Acceptance: Supposedly acknowledged by all rational agents.
Indisputable Truth: Considered beyond doubt or debate.

However, these characteristics are problematic when self-evident claims conflict with one another.

The Phenomenon of Contradictory Self-Evident Claims

Contradictory self-evident claims occur when two or more propositions, each asserted as self-evident, directly oppose each other. This situation leads to logical inconsistencies, as contradictory propositions cannot both be true simultaneously.

Examples in Moral Philosophy

Capital Punishment:
- Claim A: “It is self-evident that capital punishment is morally permissible as a form of justice.”
- Claim B: “It is self-evident that capital punishment is morally impermissible due to the sanctity of life.”
Euthanasia:
- Claim A: “It is self-evident that individuals have the right to choose death to alleviate suffering.”
- Claim B: “It is self-evident that taking a life, even one’s own, is morally wrong.”

These conflicting claims illustrate how self-evidence can lead to contradictory moral assertions.

Logical Analysis of Contradictory Claims

To examine the issue systematically, we can employ syllogistic reasoning and symbolic logic.

Syllogistic Analysis

Premise 1: Proposition $p$ is self-evident and states that action $A$ is morally obligatory.
Premise 2: Proposition $q$ is self-evident and states that action $A$ is not morally obligatory.
Conclusion: Both propositions cannot be self-evident truths simultaneously, leading to a contradiction.

Symbolic Logic

Let us define:

$S(p)$ : “Proposition $p$ is self-evident.”
$S(q)$ : “Proposition $q$ is self-evident.”
$p: O(A)$ : “Action $A$ is morally obligatory.”
$q: \neg O(A)$ : “Action $A$ is not morally obligatory.”

We have:

$S(p) \land O(A)$
$S(q) \land \neg O(A)$
Since $O(A)$ and $\neg O(A)$ are contradictory, the simultaneous acceptance of $S(p)$ and $S(q)$ leads to a logical inconsistency.
Therefore, at least one of the propositions cannot be self-evident.

This logical framework shows that contradictory self-evident claims cannot both hold true, challenging the reliability of self-evidence in moral reasoning.

Implications of Contradictory Self-Evident Claims

Questioning the Universality of Self-Evidence

The existence of contradictory self-evident claims suggests that self-evidence is not universal. If self-evident truths were truly universal, such contradictions would not occur.

Subjectivity: Self-evidence appears to be subjective, varying between individuals and cultures.
Cultural Relativism: Different societies may hold opposing moral propositions as self-evident.

Undermining the Foundation of Moral Arguments

Relying on self-evidence as a foundation for moral arguments becomes problematic when contradictory claims exist.

Lack of Resolution Mechanism: There is no clear method to resolve which self-evident claim is correct.
Erosion of Authority: The authority of self-evidence is diminished when it leads to contradictions.

Case Studies of Contradictory Self-Evident Claims

Case Study 1: Freedom of Speech vs. Protection from Harm

Proposition $p$ : “It is self-evident that freedom of speech is a fundamental right that must not be restricted.”
Proposition $q$ : “It is self-evident that speech causing harm should be restricted to protect individuals.”

These propositions conflict when considering hate speech or harmful rhetoric.

Case Study 2: Individual Rights vs. Collective Good

Proposition $p$ : “It is self-evident that individuals have the right to personal autonomy.”
Proposition $q$ : “It is self-evident that the needs of the many outweigh the needs of the few.”

Conflicts arise in scenarios like mandatory vaccinations or conscription.

The Inadequacy of Self-Evidence in Resolving Moral Disputes

Absence of Objective Criteria

Without objective criteria to determine which self-evident claim is valid, moral disputes remain unresolved.

Arbitrariness: Choosing between contradictory self-evident claims can appear arbitrary.
Bias and Prejudice: Personal biases may influence which claim individuals accept.

Necessity for External Justification

To resolve contradictions, moral propositions require justification beyond self-evidence.

Empirical Evidence: Examining the consequences of actions can inform moral judgments.
Rational Discourse: Engaging in logical reasoning and ethical debate helps evaluate conflicting claims.
Ethical Theories: Applying ethical frameworks provides structured approaches to moral issues.

Philosophical Perspectives on Contradictory Claims

Ethical Relativism

Ethical relativism acknowledges that moral truths are relative to cultural or individual perspectives, explaining the existence of contradictory self-evident claims.

Implication: There are no absolute moral truths; morality is context-dependent.

Moral Objectivism

Moral objectivism asserts that there are objective moral truths, despite apparent contradictions.

Resolution Attempt: Objectivists seek underlying principles that reconcile conflicting claims.

Constructivism

Constructivism proposes that moral truths are constructed through social processes and agreements.

Collaborative Resolution: Contradictory claims can be negotiated and harmonized through collective reasoning.

Addressing Contradictory Self-Evident Claims

Critical Examination of Self-Evident Propositions

Questioning Assumptions: Scrutinize the basis of purportedly self-evident claims.
Seeking Common Ground: Identify shared values that can bridge conflicting propositions.

Development of Ethical Frameworks

Utilitarianism: Evaluates actions based on the greatest good for the greatest number.
Deontological Ethics: Focuses on duties and adherence to moral rules.
Virtue Ethics: Emphasizes moral character and virtues.

These frameworks offer alternative means of assessing moral propositions without relying solely on self-evidence.

Conclusion

The presence of contradictory self-evident claims in moral philosophy exposes significant weaknesses in relying on self-evidence as a foundation for moral truths. Logical inconsistencies arise when different individuals or cultures assert opposing propositions as self-evident, undermining the universality and reliability of self-evidence. To address moral disputes effectively, it is necessary to move beyond appeals to self-evidence and engage in critical examination, rational discourse, and the application of ethical theories. By doing so, we can develop more robust and coherent moral arguments that are better equipped to handle the complexities of ethical dilemmas.

Produce a hypothetical dialogue between a moralist who invokes the “self-evident” nature of their own moral system and a moral non-realist.

Hypothetical Dialogue Between a Moralist and a Moral Non-Realist

Moralist (M): I firmly believe that certain moral truths are self-evident. For example, it is self-evident that causing unnecessary harm to others is wrong. This moral truth doesn’t require further justification; it’s immediately apparent to any rational person.

Moral Non-Realist (NR): I appreciate your conviction, but I question whether any moral truth can genuinely be self-evident. The concept of self-evidence in morality seems inherently subjective, influenced by personal intuitions, cultural backgrounds, or societal norms.

M: But isn’t there a universal moral intuition that tells us harming others is wrong? This seems to transcend cultural and individual differences.

NR: If moral truths were truly self-evident and universally recognized, we wouldn’t observe significant moral disagreements across different cultures and individuals. History and anthropology show us that practices considered morally acceptable in one society are condemned in another. This subjectivity suggests that moral propositions are not universally recognized as true, challenging their supposed self-evidence.

M: Perhaps those disagreements arise because some people haven’t properly reflected on these moral truths. With proper reasoning and reflection, they would recognize their self-evident nature.

NR: That leads us into circular reasoning. You’re suggesting that a moral proposition ppp is true because it’s self-evident, and it’s self-evident because it’s true. This doesn’t provide independent support for the proposition; it merely assumes its truth within its premise.

M: I don’t see it as circular. The self-evidence of a moral truth is its own justification. Just like in mathematics, certain axioms are accepted as self-evident and form the basis for further reasoning.

NR: Comparing moral truths to mathematical axioms is problematic. Mathematical propositions can be logically proven within a formal system based on universally accepted axioms. Moral propositions lack such definitive proof mechanisms and universal acceptance. They can’t be proven through logical deduction in the same way mathematical truths can.

M: Are you saying that moral truths can’t be objective like mathematical truths?

NR: Exactly. The inapplicability of mathematical objectivity to moral propositions underscores this point. While mathematical truths are derived from agreed-upon axioms and are universally recognized, moral truths are subject to personal and cultural interpretation. This means they lack the universality required for self-evidence.

M: But surely, some moral principles are universally accepted. Take the principle of honesty. Isn’t it self-evident that honesty is a virtue?

NR: Even honesty isn’t universally valued in all contexts. For instance, in some cultures or situations, deception is considered acceptable or even necessary. Moreover, different moral systems often present contradictory propositions as self-evident, leading to logical inconsistencies.

M: Can you provide an example of such contradictions?

NR: Certainly. Consider the moral proposition ppp stating that “Action AAA is morally obligatory,” and another proposition qqq stating that “Action AAA is not morally obligatory.” If both ppp and qqq are claimed to be self-evident, we have a contradiction. For example, some people consider it self-evident that euthanasia is morally permissible to alleviate suffering, while others find it self-evident that taking a life is morally wrong, regardless of circumstances.

M: Perhaps one of those groups is mistaken about the self-evident nature of their belief.

NR: But without independent criteria to determine which proposition is truly self-evident, we can’t resolve the contradiction. This highlights the insufficiency of self-evidence as a foundation for moral truths.

M: Maybe the issue is that moral truths are self-evident to those who reflect properly and think rationally about them.

NR: If that were the case, we wouldn’t see persistent disagreements among rational agents. The existence of diverse and conflicting moral intuitions suggests that moral truths are not self-evident. Rational and reflective individuals often reach different moral conclusions due to varying perspectives, experiences, and cultural influences.

M: But couldn’t these disagreements be the result of biases or lack of proper understanding?

NR: While biases can affect moral judgments, the fact that even well-informed, rational people disagree on fundamental moral issues indicates that self-evidence isn’t sufficient to establish moral truths. Additionally, relying on self-evidence can lead to dogmatism, where one refuses to consider alternative viewpoints because they believe their moral stance is unquestionably true.

M: So, if moral truths aren’t self-evident, how do we establish them?

NR: We need to move beyond appeals to self-evidence and seek independent justification for moral propositions. This involves engaging in rational discourse, providing logical arguments, and considering empirical evidence where applicable. Ethical theories like utilitarianism, deontology, and virtue ethics offer frameworks for evaluating moral claims based on reasoned analysis rather than self-evidence.

M: But those ethical theories also have their critics and aren’t universally accepted.

NR: True, but they provide structured methods for debating and analyzing moral issues, allowing for critical examination and dialogue. Unlike appeals to self-evidence, which are inherently subjective and resistant to scrutiny, these theories encourage open discussion and the possibility of reaching a consensus.

M: I see your point, but I still feel that some moral truths are so fundamental that they must be self-evident.

NR: It’s natural to have strong convictions about certain moral beliefs. However, acknowledging the subjectivity involved in perceiving something as self-evident can help us remain open to alternative perspectives and strengthen our moral reasoning through critical evaluation.

M: Perhaps we can agree that while some moral intuitions feel self-evident to us, we should be cautious about treating them as universally self-evident truths without further justification.

NR: Exactly. By recognizing the limitations of self-evidence in moral arguments, we can foster more productive discussions and work towards developing a more robust and inclusive moral framework.

M: So, moving forward, we should focus on providing reasons and evidence for our moral beliefs rather than relying solely on their apparent self-evidence.

NR: Yes, that approach allows us to engage constructively with others, address disagreements, and refine our moral understanding.

M: Thank you for this enlightening conversation. You’ve given me much to consider regarding the foundations of my moral beliefs.

NR: Likewise, I appreciate your openness to dialogue. These discussions are essential for deepening our understanding of complex moral issues.

It demonstrates the importance of seeking independent justification for moral propositions through rational discourse and ethical reasoning. By moving beyond appeals to self-evidence, individuals can engage more effectively with diverse perspectives and contribute to the development of a more coherent and inclusive moral philosophy.

Quiz

#1: What is the main weakness in invoking the self-evident nature of morality?

Answer:

The main weakness is that self-evidence is subjective, influenced by personal intuitions, cultural backgrounds, and societal norms, which leads to moral disagreements and contradictions.

#2: How does the moral non-realist argue against the idea that moral truths are self-evident?

Answer:

The moral non-realist argues that moral truths cannot be self-evident because of the persistent disagreement among rational agents, which suggests that moral intuitions are not universally shared or recognized.

#3: What is circular reasoning, and how does it relate to moral self-evidence?

Answer:

Circular reasoning occurs when the conclusion of an argument is assumed within the premises. In the case of moral self-evidence, it assumes that a moral proposition is true because it is self-evident and self-evident because it is true.

#4: What example of circular reasoning is given in the dialogue?

Answer:

The example of circular reasoning is the moral proposition that “causing unnecessary harm is wrong,” where the justification for its truth is its self-evidence, which is assumed because of the belief in its truth.

#5: Why is comparing moral truths to mathematical truths problematic according to the moral non-realist?

Answer:

Comparing moral truths to mathematical truths is problematic because mathematical truths are based on universally accepted axioms and logical deductions, while moral propositions lack such definitive proof mechanisms and universal acceptance.

#6: What are the main characteristics of mathematical objectivity that moral propositions lack?

Answer:

Mathematical objectivity involves universal acceptance, logical deduction from axioms, and the abstract nature of the truths, all of which moral propositions lack because they are subjective and influenced by cultural and individual perspectives.

#7: How does the existence of contradictory self-evident moral claims undermine the notion of self-evidence in morality?

Answer:

Contradictory self-evident claims undermine the notion of self-evidence because two opposing propositions cannot both be true, leading to logical inconsistency, which challenges the reliability of self-evidence in moral reasoning.

#8: Provide an example of contradictory self-evident moral claims discussed in the thread.

Answer:

One example is the moral claim that “capital punishment is morally permissible” versus the opposing claim that “capital punishment is morally impermissible due to the sanctity of life.” Both are argued to be self-evident, yet they contradict each other.

#9: What does the moral non-realist suggest is necessary to resolve contradictions in moral propositions?

Answer:

The moral non-realist suggests that moral propositions require external justification, such as empirical evidence, rational discourse, and the application of ethical frameworks like utilitarianism or deontology, to resolve contradictions.

#10: How does the dialogue distinguish between self-evidence in moral truths and mathematical truths in terms of proof and acceptance?

Answer:

The dialogue distinguishes them by explaining that mathematical truths can be logically proven within a formal system based on universally accepted axioms, while moral truths lack such proof mechanisms and are not universally accepted.

#11: How does the moral non-realist address the issue of moral intuitions being treated as axioms?

Answer:

The moral non-realist argues that moral intuitions cannot serve as axioms because they are not universally shared or accepted. Moral intuitions vary across individuals and cultures, unlike mathematical axioms which are universally recognized.

#12: What solution does the moral non-realist propose to improve moral reasoning and argumentation?

Answer:

The moral non-realist proposes engaging in rational discourse, providing logical arguments, and utilizing ethical frameworks to evaluate moral claims, rather than relying on subjective notions of self-evidence.

Rebut the assumptions in Quiz Item #12 from the perspective of a moral non-realist.

From the perspective of a moral non-realist, the assumptions in Quiz Item #12—that moral reasoning can be improved by engaging in rational discourse, providing logical arguments, and utilizing ethical frameworks—are based on the flawed premise that moral propositions are subject to the same kind of objective analysis as scientific or mathematical truths. Here’s a detailed rebuttal of these assumptions:

Assumption 1: Rational Discourse Can Lead to Objective Moral Truths

While rational discourse is valuable for exchanging ideas, a moral non-realist would argue that it cannot lead to objective moral truths because moral propositions are ultimately grounded in subjective emotional responses or cultural norms, not in any universal rational foundation. Morality is contingent upon human preferences, social contexts, and evolutionary processes, meaning that different individuals or societies might rationalize the same situation differently based on their unique experiences, interests, or desires. Rational discourse might help clarify why people hold particular moral views, but it cannot produce objective moral facts, because no such facts exist in the first place.

Assumption 2: Logical Arguments Can Establish Moral Truths

The belief that logical arguments can establish moral truths assumes that moral propositions are analogous to logical or mathematical propositions, which can be proven true or false. However, from a moral non-realist standpoint, moral claims do not possess truth values in the same way. They express emotions, preferences, or prescriptive norms, rather than factual states of affairs that can be logically deduced. Consequently, while logic can help clarify consistency within a moral framework, it cannot validate any particular moral claim as “true” in an objective sense.

Assumption 3: Ethical Frameworks Provide an Objective Basis for Moral Evaluation

A moral non-realist would challenge the idea that ethical frameworks such as utilitarianism, deontology, or virtue ethics provide an objective basis for evaluating moral claims. These frameworks are themselves built on normative assumptions that cannot be universally justified. For instance:

Utilitarianism assumes that maximizing happiness or minimizing harm is the ultimate good, but this is just one possible value system among many.
Deontology presupposes that certain duties or rights are intrinsically valuable, yet there is no objective reason to prefer this framework over others.
Virtue ethics focuses on character and virtues, but the conception of virtue varies widely across cultures and eras.

Because these frameworks rest on differing, subjective premises, they cannot be used to objectively determine the “correct” moral position. Instead, they serve as tools for articulating personal or collective values within particular contexts, not for discovering objective moral truths.

Conclusion

From the moral non-realist perspective, the assumptions in Quiz Item #12 are flawed because they presuppose the existence of objective moral truths that can be discovered through rational analysis. Moral discourse and ethical frameworks are tools for negotiation and understanding, but they cannot establish universally valid moral claims. Morality is fundamentally a matter of human sentiment, cultural conditioning, and pragmatic considerations, and as such, it does not lend itself to the kinds of objective analysis proposed in the question.
