From the limes to the limen. Space-theoretical Remarks on the Concept of Boundary

Abstract

Drawing on the metaphor of the train compartment, this paper explores the space-theoretical, philosophical, and phenomenological logic of the boundary as a limes and its further development into a limen. Central to this discussion are the figures of boundary and threshold and their complex and intertwined relationship in the history of thought. Through relevant, tradition-informed philosophical reflections on boundaries, as well as concrete interdisciplinary examples and terminological distinctions, it is demonstrated that the phenomenon of boundary/threshold exhibits historical-semantic depth in the mutual differentiation and dynamic interplay of the two concepts. In this framework, the boundary emerges as a true limen, which, beyond its space-theoretical dimension, operates as a cipher for broader cultural domains and ultimately carries ethical significance regarding community paradigms.
