 Error theorists treat this projection as much the same as the attribution of agency to planets in some cultures: a predictable false belief. Contemporary expressivists, in contrast, believe that attribution of moral facts and properties serves a purpose. It enables us to express our commitments in a way that provides a focal point for disagreement and debate. As discussed above, on deflationary views of truth and facts, it is a first-order question whether some attribution is in error or not (Blackburn 1998).
