In literature the term "proof" is employed in a rich variety of ways, serving as both a formal demonstration of an idea and a tangible token of evidence. Philosophical works, for instance, use “proof” to denote rigorous reasoning or logical necessity, as when Kant and Spinoza articulate modes of inference and demonstration [1, 2]. In other contexts it becomes a device to establish personal or historical veracity, whether via wagers intended to settle disputes [3] or through tokens that affirm fidelity or character [4, 5]. Authors also extend the metaphor to physical realms—for example, describing something as “fire-proof” to suggest invulnerability [6]—or to illustrate moral and social arguments where the occurrence or non-occurrence of an event stands as witness to truth [7, 8]. Across genres and eras, “proof” thus remains a versatile tool in literature, bridging the abstract demands of logic with the concrete necessities of human experience [9].
