This paper challenges a dualistic picture popularised by Nigel Pleasants at the centre of influential investigations into the possibility of Wittgensteinian forms of moral certainty. The dualistic picture takes it for granted that moral certainty concerns both a series of hinge propositions that are beyond doubt, make no sense to justify and cannot be expressed in ordinary discourse and a phenomenon that is only ever instantiated in our ways of acting. I consider tensions in this account as they relate to (...) ‘Murder is wrong’ as a moral hinge proposition by drawing on the life and lyrics of US hip‐hop artist Kendrick Lamar. My claim is that the Lamar example highlights important tensions in our relation to the wrongness of murder that many would understand to occur within the moral realm, but which are conceptually ruled out from dualistic accounts of moral certainty. The plausibility of the dualistic picture must therefore be reassessed. (shrink)
