The Structural Gap Between Reality and Perception

This paper defines Δt not as temporal delay but as a structural gap between reality and perception. It proposes a generative chain: Open → Unstable → Selection → Difference → Being (condition) → Reality (state) → Δt → Experience → Time/Space. Being is defined as an open condition rather than a closed substance, and therefore inherently unstable. Instability necessitates selection; selection generates difference; difference establishes being as a condition. Reality emerges as a state from this condition, but perception cannot coincide with reality. This structural non-coincidence constitutes Δt. Experience is only possible through Δt. Time is defined as the accumulation of Δt experiences, and space as their distribution. Boundary conditions are specified: Δt cannot be continuously zero; Δt approaching infinity collapses perception; reality is continuous while perception is discrete. This framework integrates ontology, epistemology, and spatiotemporal formation into a single structural model.
