Literary notes about Useful (AI summary)
In literature, "useful" serves as a versatile descriptor that underscores both practical utility and moral or intellectual value. It is employed to highlight the beneficial qualities of subjects ranging from scientific disciplines—such as geography being both “useful and interesting” [1] or hygiene being “the only useful part of medicine” [2]—to human relationships and character, with individuals noted for their contributions to society [3] or personal growth [4]. Philosophical texts even scrutinize its inherent value, pondering whether things are good because they are useful or vice versa [5]. Thus, across genres and eras, "useful" conveys a sense of necessary practicality while also inviting reflection on what qualities justify its designation.
