Boncompagni proposes an alternative to the current concern with conceptual engineering and focuses not on the deliberate alteration of concepts but instead on how concepts evolve in response to and along with social changes. Beginning with an examination of the ways that Charles Peirce, William James, and John Dewey understood conceptual change, she derives an understanding of concepts as “evolving inferential tools.” This understanding enables conceptual engineers to avoid the “Strawsonian challenge,” according to which altering the extension and intension of a concept does not change the concept so much as it changes the subject altogether. But the project of conceptual engineering still faces “Lenin’s problem”: the danger that in attempting to alter a concept, even well-intentioned engineers are ultimately trying to change the “consciousness of the marginalized.” Inspired by Jane Addams’s idea of sympathetic knowledge, Boncompagni presents an alternative to conceptual engineering that she calls conceptual care: the development of tools to assist the growth of new and emerging concepts in marginalized communities.
