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)

I exploit parallel considerations in the philosophy of mind and metaethics to argue that the reasoning employed in an important argument for panpsychism overgeneralizes to support an analogous position in metaethics: panmoralism. Next, I raise a number of problems for panmoralism and thereby build a case for taking the metaethical parallel to be a reductio ad absurdum of the argument for panpsychism. Finally, I contrast panmoralism with a position recently defended by Einar Duenger Bohn and argue that the two suffer (...) from similar problems. I conclude by drawing some general lessons for panpsychism. (shrink)

In both the early modern period and in contemporary debates, philosophers have argued that there are analogies between mathematics and morality that imply that the ontology and epistemology of morality are crucially similar to the ontology and epistemology of mathematics. I describe arguments for the math‐moral analogy in four early modern philosophers (Locke, Cudworth, Clarke, and Balguy) and in three contemporary philosophers (Clarke‐Doane, Peacocke, and Roberts). I argue that these arguments fail to establish important ontological and epistemological similarities between morality (...) and mathematics. There are analogies between the two areas, but the disanalogies are more significant, undermining the attempt to confer on morality the same ontological and epistemological status that mathematics possesses.
