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.

This paper identifies and elucidates the underappreciated phenomenon of epistemic domination. Epistemic domination is the nonmutual capacity of one party to control the evidence available to another. Where this capacity is exercised, especially by parties that are ill-intentioned or ill-informed, the dominated party may have difficulty attaining epistemically valuable states. I begin with a discussion of epistemic domination and how it is possible. I then highlight three negative consequences that may result from epistemic domination.

What determines whether an object is an artwork? In this paper I consider what I will call ‘social’ theories of art, according to which the arthood of objects depends in some way on the art-related social practices that we have. Though such a dependence claim is plausible in principle, social theories of art tend to unpack the determining link between artworks and social practices in terms of intentional relations between the objects in question and the people involved in the relevant practices. This intentionalism has unappealing upshots. Drawing on two-dimensional approaches in social ontology, I show how social theories of art can be done differently, improving their prospects.

The paper replies to Matthew Rellihan’s recent criticism of Thomas Kroedel’s simple argument for downward causation. Rellihan argues that the simple argument equivocates between two notions of realizers of mental properties, namely total realizers and core realizers. According to Rellihan, one premise of the argument is false on each disambiguation. In response, this paper argues that the version of the argument in terms of total realizers is sound after all if we evaluate counterfactual conditionals about the non-occurrence of total realizers correctly.

If there are true contradictions, where are they? In language or in the world? According to one important view, best represented by Jc Beall (2009), only the former. In this paper, we raise a problem for this view. In order to defend a “merely semantic” version of dialetheism (aka ‘glut theory’), Beall adopts transparent accounts of truth and falsity, which gives rise to “dialethic ascent” on which true contradictions are also, contradictorily, untrue contradictions. This is a consequence of trying to restrict contradictions to language and keep them out of the world. However, in this paper, we show that this ascent carries over intensional contexts, so that, on this version of dialetheism, even if there are true contradictions, no one knows a true contradiction. This shows that contradictions have not been kept out of the world. We end by connecting this issue with the infamous ‘just true’ problem.

According to the principle of conditional power aggregation (CPA), conditional powers conjoin when the properties that bestow them conjoin. Sophie Gibb has argued that CPA is false given Shoemaker’s account of conditional powers and that this leads to a problem for his account of subset realization. In short: If CPA is rejected, subset realization fails to be an entailment relation, in which case it cannot provide a basis for non-reductive physicalism. I defend the subset account against this argument by denying that CPA fails. I argue that (i) Shoemaker’s account of conditional powers does not warrant a rejection of CPA, (ii) his account is incomplete and should be supplemented with a further sufficient condition for when a property bestows a conditional power, and (iii) this further sufficient condition supports CPA.

Gonzalo Rodriguez-Pereyra has presented an objection to the co-intension problem. According to this objection, the examples of properties often cited to motivate the co-intension problem are actually relational properties, and so turn out not to be co-intensional. In this essay, I want to revisit Rodriguez-Pereyra’s objection and explain why I find it defective.

Timothy Williamson contends that our primary cognitive heuristic for prospectively assessing conditionals, i.e., the suppositional procedure, is provably inconsistent. Our diagnosis is that stipulations about the nature of suppositional rejection are the likely source of these results. We show that on at least one alternative, and quite natural, understanding of the suppositional attitudes, the inconsistency results are blocked. The upshot is an increase in the reliability of our suppositional heuristics across a wider range of contexts. One interesting consequence of the increased reliability is a proportional decrease in the plausibility of an error-theory that Williamson employs against widespread intuitions about the truth values of counterpossible conditionals.
