Are moral values merely subjective cultural inventions rather than objective universal truths?
Debates whether moral statements (like 'murder is wrong') reflect mind-independent objective moral truths or subjective social contracts and evolutionary biology.
Pick a Side
Choose a position to defend, or let fate assign your stance.
Arguments FOR
1. Vast cross-cultural and historical disagreement over core moral values
Human cultures have celebrated human sacrifice, slavery, cannibalism, and patriarchal conquest as moral virtues, proving morality is culturally constructed.
2. Evolutionary psychology fully explains moral emotions without metaphysical facts
Altruism, kin fairness, and tribal shame evolved naturally as adaptive survival traits in social primates, not because invisible moral particles exist in the cosmos.
3. J.L. Mackie's Argument from Queerness
Objective moral facts would have to be bizarre, metaphysical entities completely unlike anything else in the physical universe that somehow compel action.
4. Fosters humility and prevents violent moral imperialism
Belief in absolute objective moral truth historically justified colonial crusades, inquisitions, and cultural destruction under the belief of possessing divine truth.
Arguments AGAINST
1. Moral relativism makes moral progress and social reform impossible
If morality is merely cultural convention, abolitionists who fought slavery in the 1800s were 'immoral' because they violated their culture's established norms.
2. Cannot condemn monstrous atrocities across borders
A relativist cannot logically condemn genocide, apartheid, or female genital mutilation in another culture, reducing morality to 'anything goes if accepted locally'.
3. Conscious suffering provides an objective biological foundation
Sam Harris and moral realists demonstrate that the difference between the worst possible misery for everyone and flourishing is an objective, measurable fact.
4. Relativism is self-refuting in philosophical logic
If the relativist claims 'it is an objective universal truth that no objective universal moral truths exist,' they contradict their own foundational premise.
Counter Questions
Questions to challenge claims and probe deeper into trade-offs.
- If morality is purely subjective culture, on what basis can we say the abolition of slavery was an objective moral improvement?
- Why did philosopher J.L. Mackie argue that objective moral values would be 'entities of a very strange sort, utterly different from anything else in the universe'?
- Can a moral relativist condemn the Holocaust as objectively evil without contradicting their own philosophical framework?
- Could moral facts be objective in the exact same way that mathematical truths (like 2+2=4) exist independently of human opinion?
- Does the existence of universal biological human needs (food, safety, love) provide a grounding for objective human ethics?
