The concept of "exterior" refers to the outer aspect of a three-dimensional object, acting as a boundary between the internal and the external. Authors have long examined this theme through various perspectives: Hegel equated exterior with interior, claiming their shared essence, while Shelley evoked the eerie beauty of distant landscapes as a channel for transcendent thought.
Geikie emphasized nature’s ability to unveil concealed meanings, and Owen observed how the natural world evokes deep emotions, elevating everyday existence. These viewpoints collectively highlight the exterior not merely as a surface, but as a reflection of inner truths and existential connections.
