Conceptual engineering (CE) is the program of deliberately and systematically assessing our concepts, with a view to improving or, where required, replacing them by superior ones (e.g. Cappelen, 2020, p. 132; Eklund, 2021, p. 15). ‘CE’ can refer either to the assessment and amelioration of a conceptual system through philosophical means, or to the meta-philosophical debate on the nature, scope and limits of that philosophical activity. The two sometimes go hand-in-hand, nevertheless it is important to keep them apart. The current debate remains marked by a preponderance of meta-philosophical ruminations over philosophical performance. But for the sake of such ruminations it is convenient to use the label for the philosophical enterprise, unless otherwise specified.
