Expressivism has been dominating much of the metaethical debate of the past three decades. The aim of this book is to address a number of questions that have been neglected in the previous discussion.These primarily concern the psychological commitments and the methodological status of expressivism as well as important differences and similarities between the approaches of the 'classic' expressivists Ayer, Stevenson, Hare, Blackburn und Gibbard.
