The term "contiguity" has been employed in literature as a multifaceted concept, spanning from physical proximity to the underlying principles of association in human thought. In classical texts, authors like David Hume and George Santayana use it not only to describe spatial and temporal nearness—see for instance Hume’s discussions on space and time [1, 2, 3] and Santayana’s references to practical, empirical connections [4, 5, 6]—but also to ground theories of causation and mental association [7, 8, 9, 10, 11]. Outside philosophy, the word takes on tangible spatial meaning: Suetonius [12] illustrates it by referring to land distribution, while Thomas Hardy [13] and Bret Harte [14] allude to its convenience in terms of location. Even in the realm of magical and psychological discourse, as seen in Frazer [15] and Freud [16, 17], contiguity is posited as a fundamental relation—often juxtaposed with similarity—that organizes both physical and abstract connections. This varied usage underscores how the concept of contiguity has served as a bridge linking practical, empirical realities with the more elusive dynamics of thought and association.
