Throughout these works, the word “types” appears in a variety of contexts to denote categories, classifications, and exemplars. It can refer to distinct products—like Jamaica’s “two distinct types of coffee” [1]—or symbolic forms, such as “spiritual types” in discussions of good and evil [2]. In other cases, authors apply it to human traits—for instance, contrasting Puritan figures as “two extreme types” [3] or distinguishing among “two types of Methodist” [4]. Still elsewhere, “types” helps structure scientific or psychological inquiry—whether classifying “types of reproduction” in witness testimony [5] or delineating “different types of delusions” [6]. Across all these diverse sources, “types” underpins a recurring literary and scholarly practice of grouping ideas or objects into meaningful sets.
