What is conceptual engineering good for? The argument from nameability

Abstract It is often assumed that how we talk about the world matters a great deal. This is one reason why conceptual engineers seek to improve our linguistic practices by advocating novel uses of our words, or by inventing new ones altogether. A core idea shared by conceptual engineers is that by changing our language in this way, we can reap all sorts of cognitive and practical benefits, such as improving our theorizing, combating hermeneutical injustice, or promoting social emancipation. But how do changes at the linguistic level translate into any of these worthwhile benefits? In this paper, we propose the nameability account as a novel answer to this question. More specifically, we argue that what linguistic resources are readily available to us directly affects our cognitive performance on various categorization‐related tasks. Consequently, our performance on such tasks can be improved by making controlled changes to our linguistic resources. We argue that this account supports and extends recent motivations for conceptual engineering, as categorization plays an important role in both theoretical and practical contexts.
