This paper explores the metaethical ramifications of a coarse-grained criterion of property identity, sometimes referred to as Hume's dictum. According to Hume's dictum, properties are identical if and only if they are necessarily co-extensive. Assuming the supervenience of the normative on the natural, this criterion threatens the non-naturalist view that there are instantiable normative properties which are distinct from natural properties. In response, non-naturalists typically point to various counterintuitive implications of Hume's dictum. The paper clarifies this strategy and defends it (...) against objections by Bart Streumer and Ralf Bader. In addition, it is argued that proponents of naturalist and supernaturalist views, along with proponents of a certain kind of nihilism, should also reject Hume's dictum. This shows that non-naturalists can also attack the criterion indirectly, by pointing to partners in guilt. Also, it shows that not just any opponent of non-naturalism can appeal to Hume's dictum. Only certain nihilists can. (shrink)

Most error theorists want to accept hypothetical reasons but not moral reasons. They do so by arguing that there is no queerness in hypothetical reasons. They can be reduced to purely descriptive claims, about either standards or ordinary standard-independent facts: when I say “I have a reason to take this flight, ” all I say is that “according to certain standards of reasoning, I have a reason to take this flight” or that “I have a desire such that taking this (...) flight is the only way of doing so.” Error theorists who want to accept hypothetical reasons but not moral reasons think that one of these approaches works for hypothetical reasons but neither work for moral reasons. I shall argue that whatever arguments are given for rejecting these approaches in the case of moral reasons are also arguments for rejecting them in the case of hypothetical reasons. (shrink)

Debunking arguments in metaethics are often presented as particularly challenging for non‐naturalistic versions of moral realism. The first aim of this paper is to explore and defend a response on behalf of non‐naturalism. The second aim of the paper is to argue that although non‐naturalism’s response is satisfactory, this does not mean that debunking arguments are metaethically uninteresting. They have a limited and indirect role to play in the exchange between non‐naturalists and moral error theorists. In the end, debunking arguments (...) can do less for sceptics and nihilists than what is commonly thought, but not nothing. (shrink)

Normativni teoretičari pogreške nastoje braniti teoriju pogreške koja kaže da normativni sudovi pripisuju normativna svojstva, a takva svojstva, uključujući razloge za vjerovanje, nikada nisu instancirana. Mnogi filozofi su iznijeli prigovore obrani teorije koja podrazumijeva da ne možemo imati razloga vjerovati u nju. Spencer Case prigovara da teoretičari pogreške jednostavno ne mogu izbjeći samopobijanje. S druge strane, Bart Streumer tvrdi da ne možemo vjerovati u normativnu teoriju pogreške, ali da to, pomalo iznenađujuće, pomaže njenim zagovornicima da je obrane od ovih prigovora. (...) Smatram da, ako je Streumerov argument uspješan, on omogućuje teoretičarima pogreške izbjegavanje Caseovog prigovora o samopobijanju. Međutim, nadograđujem i poboljšavam Caseov argument kako bih pokazao da nikada ne bismo mogli uspješno obraniti normativnu teoriju pogreške, bez obzira na to možemo li vjerovati u nju ili ne. Dakle, samopobijanje ostaje. Rad zaključujem nudeći neke razloge za mišljenje da naša nesposobnost da obranimo normativnu teoriju pogreške znači da bismo je trebali odbaciti, što bi posljedično značilo da je ona neistinita.

We have no reason to believe that reasons do not exist. Contra Bart Streumer’s recent proposal, this has nothing to do with our incapacity to believe this error theory. Rather, it is because if we know that if a proposition is true, we have no reason to believe it, then we have no reason to believe this proposition. From a different angle: if we know that we have at best misleading reasons to believe a proposition, then we have no reason (...) to believe it. This has two consequences. Firstly, coming close to believing the error theory is idle or pointless. Secondly, philosophers who argue that believing sweeping theories like determinism or physicalism is self-defeating because they are either false or believed for no reason pursue a worthwhile argumentative strategy.
