Conceptual engineering is the method of critically assessing, improving, and replacing the concepts we use in thought and talk. Based on lectures by leading philosophers at the Conceptual Engineering Online Seminar 2020–2022, this second of three volumes develops novel connections between conceptual engineering and a variety of fields and methods in analytic philosophy. It applies conceptual engineering to various philosophical questions and explores its relation to established philosophical practices. It is of interest to professional philosophers with expertise in metaphilosophy or those who seek to apply the methods of conceptual engineering to issues in their own areas of specialization, as well as philosophy students who want to get acquainted with the exciting and dynamic methodological developments of their discipline. This volume includes chapters by Kwame Anthony Appiah, Sanford Goldberg, Frank Jackson, Tristam McPherson & David Plunkett, Teresa Marques, Mari Mikkola, Jennifer Nado, and Mona Simion.
