The now vast list of references includes works on more general or conceptual issues, such as describing the nature of conceptual engineering, how we may respond to the different objections to it, how it is related to philosophical analysis or empirical philosophy, or toward which target conceptual engineering should be directed, among others. But research on the topic also includes applications of conceptual engineering to many different areas. This Introduction opens with a short overview of the state of the art on conceptual engineering, aiming to clarify the most important features associated with it. The Introduction moves on to introduce and discuss the eight articles collected here, whose topics range from the nature and the functionality of conceptual engineering to reconstructing the entire conceptual engineering practice. Taken as a whole, this special issue is meant to provide enlightening, informative, and thought-provoking views on the topic, its functions, targets, and challenges.eng© 2025 The Author(s).
