The word “includes” in literature often functions as a tool to specify the boundaries of a set or category, clarifying what is incorporated into a broader concept. For instance, Plato uses it to distinguish between different realms by stating that “Music includes literature” [1], while also highlighting exclusionary nuance when a character remarks that the word “every one” hardly includes him [2]. Authors extend its use to enumerate concrete components, such as when Scott describes time as comprising “Six Days” divided into cantos [3] or when literal jurisdictions are detailed, like a government that exists as part of a larger body politic [4]. At the same time, “includes” can emphasize abstract wholes, from Darwin’s explanation of natural variation encompassing both monsters and varieties [5] to Dewey’s reflection on experience, which includes liberating introspection [6]. In each case, the term serves to both delineate and unify elements within a complex system or idea.
