The word “non” functions as a versatile negator in literature, used to indicate absence, denial, or a contrast in meaning. In classical works and philosophical texts, authors employ “non” to mark what is lacking or to reject a particular state or quality—as seen in Kant’s remark that “nothing happens by blind chance (in mundo non datur casus)” ([1]) and Cicero’s critical expositions ([2], [3]). In poetic and narrative works, “non” emphasizes exclusion or negation, whether in a literary refrain like Marie Lebert’s “Non pas les débats sur la reproduction…” ([4]) or in characterizing identities as in “my only source of anxiety now was the non-appearance of Holmes” ([5]). Furthermore, “non” appears as a prefix in modern descriptive contexts, transforming adjectives to denote a specific absence such as “non-intoxicating” coffee ([6]) or “non-resident” status ([7]). This widespread use—from ancient Latin maxims to contemporary expressions—demonstrates how “non” consistently contributes a nuanced layer of meaning that both defines and refines the subject by what it specifically excludes.
