Abstract

Sally Haslanger (2020a, 2020b) proposes a way for semantic amelioration to avoid the ‘topic continuity problem’ (TCP) in conceptual engineering. TCP maintains that changing a concept’s content replaces the concept. Since this occurs in semantic amelioration, semantic amelioration necessarily seems an instance of conceptual replacement. Haslanger rejects this, however, maintaining that a concept’s function is essential to it, not its content. And since semantic amelioration doesn’t change a concept’s function, semantic amelioration isn’t conceptual replacement, according to Haslanger. In this paper, I argue that Haslanger’s account of semantic amelioration requires a change in a concept’s function. Thus, semantic amelioration is in fact conceptual replacement on Haslanger’s account. To fix this, I propose combining Amie Thomasson’s (2020) work on concepts with Haslanger’s to yield a new functional essentialist view of concepts.
