The Boundary-Freedom Law: Unifying the Existential Logic of Human and Technical Systems

Existence is not a singular property but consists of two intrinsic attributes: boundary, which grants stability and recognizability, and freedom, which grants openness and generativity. The Boundary-Freedom Law states that any existent has a decidable boundary and an open interior. This structure applies equally to human systems and technical systems, revealing their ontological commonality and functional complementarity. Starting from these two intrinsic attributes, this paper develops a cross-domain universality analysis, proceeds through the convergence from differences to sameness, and ultimately establishes the law as a formula of Dao - a universal structural logic from stability to creativity.
