Recently, theorists have pointed to the role of improvisation in practical reasoning and in gaining new moral knowledge. Laura and François Schroeter have gone even further by suggesting an account of competence with evaluative terms based on holistic improvisation. I argue, however, that they fail in their task. Through a challenge of their key claim against Allan Gibbard’s alternative account, I demonstrate that Schroeter and Schroeter provide only partial constraints on competence, and thus that their account lacks the content to (...) provide an alternative to substantive accounts in metaethics such as minimalism and neo-descriptivism.
