Abstract

Conceptual engineers have recently turned to the notion of conceptual functions to do a variety of explanatory work. Functions are supposed to explain what speakers are debating about in metalinguistic negotiations, to capture when two concepts are about the same thing, and to help guide our normative inquiries into which concepts we should use. In this paper, I argue that this recent “functional turn” should be deflated. Contra most interpreters, we should not try to use a substantive notion of conceptual functions to handle various problems for conceptual engineering. The primary accounts of function appealed to by conceptual engineers, namely etiological and system functions, are not suited to handle many of the problems functions are supposed to handle, and it’s dubious whether any other account of function would do better. Instead of trying to use substantive functions to solve theoretical problems, we should deflate those problems themselves by focusing only on what matters to us, as speakers or theorists, in a given inquiry.
