Faultless Disagreement as Evidence for Moral Relativism

Open access
Denning, Patrick, Philosophy Documentation Center·2022·Thought: A Journal of Philosophy

Abstract

Arguments from faultless disagreement appeal to the possibility of mistake-free disagreement as evidence for semantic relativism. Typically, these arguments focus on paradigmatically subjective topics such as taste, aesthetics, and comedy. Many philosophers hold that ethics is also a subjective topic. But so far, there has been little discussion of faultless disagreement in ethics. In this paper, I advance an argument from faultless moral disagreement, in favour of a relativist semantics for ethics.

TL;DR

The paper argues that a modified, experimental version of the faultless-disagreement argument can support a relativist semantics for ethics, even though the standard intuition-based version cannot be dialectically extended to ethics. It claims that ordinary speakers’ responses to cross-cultural moral disagreement are best explained by a relativist-friendly hypothesis, which entails semantic relativism over contextualism and invariantism.

Key findings

  • The standard argument from faultless disagreement cannot be effectively extended to ethics because metaethicists disagree about whether moral cases like Eccentria and Ford seem faultless; there is no consensus analogous to taste or aesthetics.
  • Experimental data from Sarkissian et al. (2011) and Khoo and Knobe (2016) show a relation between cultural distance and faultlessness: same-culture condition tended to reject faultless disagreement, other-culture condition tended to suspend judgement, and extraterrestrial condition tended to endorse faultless disagreement.
  • Khoo and Knobe also found that all three groups regarded the differences of opinion as genuine disagreements, and that participants tended to reject faultless disagreement in a non-moral extraterrestrial case while tending to endorse it in the moral case.
  • The data support group/cultural relativism but undermine individualistic relativism, because individual relativism entails that intracultural disagreement can be faultless, while ordinary speakers deny this.

Methods

  • The paper is a philosophical argument with two premises: the Ordinary Practice Claim (ordinary speakers endorse the possibility of faultless moral disagreement) and the Explanation Claim (relativism better explains this than rival descriptivist views).
  • It draws on existing experimental studies: Sarkissian et al. (2011), which exclusively recruited undergraduates, and Khoo and Knobe (2016), which recruited participants with average ages of 28, 29, and 36 across three experiments via Amazon Mechanical Turk.
  • Participants were divided into same-culture, other-culture, and extraterrestrial conditions and asked whether at least one party must be mistaken or whether both could be correct; Khoo and Knobe additionally tested rejection and perceptions of disagreement. The paper compares relativism, contextualism, and invariantism as explanations of these results.

Limitations

  • The paper states that it leaves expressivist and hybrid-expressivist semantics for another occasion and remains neutral on whether nondescriptivist theories may provide a better account.
  • It states that the experimental data are insufficiently fine-grained to adjudicate the contextualist points, so subsection 3.3 appeals to readers’ intuitions rather than the data.
  • It states that the data provide at most qualified support for relativism, that the extraterrestrial condition is far-fetched and shows only weak endorsement, and that cultural relativism is assumed in what follows. Evident from the text: the paper presents no new empirical study and relies on prior experiments and philosophical intuition.

      Experiment 3’s Methods (§2.4.1) show that Khoo and Knobe tested a non-moral disagreement involving an extraterrestrial speaker. Its Results (§2.4.2) found no significant difference between rejection and incorrectness ratings for that vignette. But they did not vary cultural distance in the non-moral conditions, so this was not a failed test of cultural distance’s effect on non-moral disagreement. (LLM, conf=0.87)

      Study 2 and its Discussion report that a Singaporean student sample showed the same pattern as the American undergraduates, giving reason to doubt that the results reflect an idiosyncrasy of contemporary American culture. The paper does not establish that the pattern extends beyond students, so it does not fully address undergraduate-specific relativism. (LLM, conf=0.82)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
