A student argues: 'People across cultures and throughout history have disagreed deeply about moral questions — slavery, punishment, gender roles. This persistent disagreement proves there are no objective moral facts.' What is the strongest objection to this argument?
AMoral disagreement is actually quite rare — most cultures converge on the same basic moral principles
BPeople also disagree persistently about scientific and historical questions, yet we don't conclude those domains lack facts — disagreement could reflect epistemic failure rather than the absence of facts
CThe argument proves too much: by the same logic, disagreements in mathematics would show there are no mathematical truths
DMoral intuitions are universally reliable, so the apparent disagreement must stem from cultural misunderstanding
The parallel to scientific disagreement is the strongest objection: deep, persistent disagreement exists in science and history, yet we don't take it to show those domains lack facts. The disagreement could reflect bias, limited perspective, or self-interest — epistemic failures — rather than the absence of a fact of the matter. The explainer notes that the troubling feature of moral disagreement is the *pattern* (views tracking social position rather than evidence), but this is a difference of degree, not a proof that no moral facts exist. Option C is also in the vicinity but overstates the case — mathematical disagreements are rare and resolvable, unlike persistent moral or scientific ones.
Question 2 Multiple Choice
Which position in moral epistemology holds that we access basic moral truths through a faculty analogous to perception — directly and without constructing arguments?
AMoral rationalism, which derives moral truths from the first principles of reason alone
BExpressivism, which holds that moral claims express attitudes rather than reporting facts
CMoral intuitionism, which holds that we perceive basic moral truths non-inferentially
DConstructivism, which holds that moral truths emerge from idealized deliberation among rational agents
Moral intuitionism (associated with G.E. Moore and W.D. Ross) holds that basic moral truths — that suffering is bad, that promises create obligations — are grasped directly, without inference, through something like a perceptual faculty. The analogy to perception is compelling because we do seem to recognize some moral truths without argument. But the analogy has limits: perceptual faculties can be cross-checked against each other and against independent evidence, while moral intuitions sometimes conflict irreducibly with no equivalent of physical measurement to adjudicate.
Question 3 True / False
An antirealist about morality must provide an account of moral justification that does not appeal to the existence of mind-independent moral facts.
TTrue
FFalse
Answer: True
This is precisely the antirealist's epistemological task. If there are no moral facts to be known, then moral discourse must be doing something other than reporting those facts. Emotivists say it expresses attitudes; prescriptivists say it prescribes behavior; constructivists say it coordinates social norms through idealized deliberation. On each of these views, 'justifying' a moral belief means showing it coheres with reflective commitments or survives scrutiny from multiple perspectives — not demonstrating that it tracks a mind-independent reality. The antirealist preserves moral argument while denying it terminates in moral knowledge.
Question 4 True / False
Persistent cross-cultural moral disagreement is stronger evidence against the existence of moral facts than persistent cross-cultural scientific disagreement is against the existence of scientific facts.
TTrue
FFalse
Answer: False
By parallel reasoning, disagreement in both domains could reflect epistemic failure — bias, limited evidence, self-interest — rather than the absence of facts. The mere existence of disagreement does not distinguish the two cases. What the explainer does note is that the *pattern* of moral disagreement (where views tend to track social position and self-interest rather than evidence) is more troubling than the pattern of scientific disagreement. But this is a difference of degree, not a difference in kind sufficient to prove that morality lacks facts while science has them.
Question 5 Short Answer
Why does a moral realist face a distinctive epistemological challenge that does not arise in the same way for a scientific realist about the physical world?
Think about your answer, then reveal below.
Model answer: A moral realist must explain how human minds make contact with moral facts — facts that, unlike physical objects, cannot be directly observed, measured with instruments, or checked against independent physical evidence. Perceptual faculties can be cross-checked against each other and calibrated against the world; moral intuitions sometimes conflict irreducibly without any equivalent procedure to adjudicate. The pattern of moral disagreement — views tracking cultural position and self-interest more than evidence — suggests that even if moral facts exist, our epistemic access to them is far more distorted than our access to physical facts.
The moral rationalist tries to solve this by grounding moral knowledge in reason (as Kant does) rather than perception, giving it an a priori foundation that doesn't require contact with external facts. The moral intuitionist accepts the perceptual analogy but must then explain why moral intuitions conflict as persistently as they do. Neither solution is fully satisfying, which is why moral epistemology remains one of the most contested areas in philosophy.
