Are there really any dual‐character concepts?

Abstract

There has been growing excitement in recent years about “dual‐character” concepts. Philosophers have argued that such concepts can help us make progress on a range of philosophical issues, from aesthetics to law to metaphysics. Dual‐character concepts are thought to have a distinctive internal structure, which relates a set of descriptive features to an abstract value, and which allows people to use either the descriptive features or the abstract value for determining the extension of the concept. Here, we skeptically investigate the central argument in favor of their existence. Across three new empirical studies, we systematically demonstrate that the linguistic patterns that dual‐character concepts were originally posited to explain are likely better explained by much more general features of language use.
