Contiguity, the condition of being closely adjacent or interconnected, has been examined across various disciplines as a foundational idea that links spatial, mental, and social phenomena. Geographers such as Augustus J. Thébaud explored its influence on the formation of national identities through shared boundaries, while Henri-Louis Bergson investigated its psychological significance, contending that perception frequently favors overall impressions rather than isolated components.
Alfred Binet, in turn, considered contiguity's role in cognition, differentiating it from simple similarity in how it organizes human comprehension of relationships. These diverse viewpoints highlight contiguity's dual nature as both a physical and abstract link, connecting geography, philosophy, and the processes of thought.
