The Practical Implementation Challenge: A Pragmatist Response to Deutsch’s Dilemma for Conceptual Engineers

According to Max Deutsch, conceptual engineers face a dilemma: either they target semantic meanings, in which case they are engaged in an infeasible activity (the “implementation challenge”), or they target speaker meanings, in which case they are engaged in a trivial enterprise (the “trivialization challenge”). Focusing on the first horn of the dilemma, I argue that the “transubstantiation version” of the implementation challenge only holds for representationalist approaches to conceptual engineering, according to which concepts are individuated by their representational relation to phenomena or sets of objects in the world. From a non-representationalist (e.g. pragmatist) perspective, the dilemma is therefore dissolved. Nevertheless, Deutsch’s article still deserves a response from the pragmatist, since it raises a more general challenge to conceptual engineering that I dub the “practical implementation challenge”. I offer a pragmatist solution to that challenge, drawing on John Dewey’s theory of inquiry and Robert Brandom’s inferentialism. This solution includes recommendations distributed across all stages of the engineering process, in privileging projects that are (1) problem-driven, (2) bottom-up; ensuring that the proposal is (3) clearly justified, (4) maintains continuity with the existing inferential role; and finally, in (5) enforcing the novel concept in practices of deontic scorekeeping, (6) backed up by institutional or intellectual authority.
