According to the argument from moral disagreement, the existence of widespread or persistent moral disagreement is best explained by, and thus supports, the view that there are no objective moral truths. One of the most common charges against this argument is that it “overgeneralises”: it implausibly forces its proponents to also deny the existence of objective truths about certain matters of physics, history, philosophy, etc. (“companions in guilt” objections) or even about the argument’s own conclusion or its own soundness (“self-defeat” (...) objections). My aim in this article is to provide a detailed clarification and assessment of this overgeneralisation charge. Various (mostly empirical) issues relevant to assessing the above objections have so far not been sufficiently investigated. Nevertheless, there are good reasons to believe that realists have exaggerated the significance of their overgeneralisation charge. Both its companions in guilt and its self-defeat versions likely fail. (shrink)

Presenting the first comprehensive, in-depth study of hyperintensionality, this book equips readers with the basic tools needed to appreciate some of current and future debates in the philosophy of language, semantics, and metaphysics. After introducing and explaining the major approaches to hyperintensionality found in the literature, the book tackles its systematic connections to normativity and offers some contributions to the current debates. The book offers undergraduate and graduate students an essential introduction to the topic, while also helping professionals in related (...) fields get up to speed on open research-level problems.

Background conditions are thought to explain how objects can have value in virtue of certain features and how reasons can consist in certain facts. The following paper provides an account of what background conditions are and what effect they have on normative features. It defends the idea that if values depend on reasons, then there is nothing really surprising or mysterious about the presence of background conditions in normative explanations. Background conditions turn out to be a natural and predictable result (...) of normative hierarchies that treat reasons as metaphysically fundamental relative to other normative features. The account is also shown to have advantages over competing accounts in that it is able to capture the functional criteria that characterize background conditions while remaining theoretically parsimonious.

Externalists argue that motivation is external to moral judgments on the grounds that people can be unmoved by their moral judgments. I reply that people sometimes act indifferently to their moral considerations not because their moral judgments lack motivation but because their moral judgments are obstructed by rival desires. It appears that the moral motivation wanes while the moral judgments linger. In reality, however, the moral motivation is only made inconspicuous by the motivation of the opposing desires. A moral judgment (...) is subject to obstruction just like an emotive judgment and a gustatory judgment. (shrink)

Almost all participants in the debate about the ethics of accidents with self-driving cars have so far assumed moral universalism. However, universalism may be philosophically more controversial than is commonly thought, and may lead to undesirable results in terms of non-moral consequences and feasibility. There thus seems to be a need to also start considering what I refer to as the “relativistic car” — a car that is programmed under the assumption that what is morally right, wrong, good, bad, etc. (...) is determined by the moral beliefs of one’s society or culture. My investigation of this idea involves six steps. First, I explain why and how the moral universalism/relativism debate is relevant to the issue of self-driving cars. Second, I argue that there are good reasons to consider accident algorithms that assume relativism. Third, I outline how a relativistic car would be programmed to behave. Fourth, I address what advantages such a car would have, both in terms of its non-moral consequences and feasibility. Fifth, I address the relativistic car’s disadvantages. Finally, I qualify and conclude my considerations. (shrink)
