Why have so many philosophers agonised over the possibility of valid arguments from factual premises to moral conclusions? I suggest that they have done so, because of worries over a sceptical argument that has as one of its premises, `All moral knowledge must be non-inferential, or, if inferential, based on valid arguments or strong inductive arguments from factual premises'. I argue that this premise is false.
