This paper proposes a meta-theoretical framework entitled "The Theory of Recursive Causality." Its core proposition is: **Any existence can be understood as the simultaneous condensation of conditions across multiple levels, presenting itself as a result at the present section, with the result automatically serving as new conditions for the next section, thereby forming a recursive causal ring.** The framework consists of five core components: condition, level, causal ring, section, and perception. Among them, perception is positioned as the "inner illumination" emerging from a qualitative change in complexity, functioning as an effective node within the causal ring rather than a mere bystander. This version (2.0) has been restructured based on a series of dialogues with the author, incorporating the following core additions: the mechanism of "automatic" section progression (the inherent instability of difference); a complete definition of superposition (horizontal superposition, complexity superposition, and vertical superposition); the positioning of level as a meta-theory in its own right; memory and history as necessary byproducts of the three-dimensional progression of sections; perception as a phase transition point of complexity; and the structural lag between the cosmic "rolling" and the human section. The Theory of Recursive Causality does not claim to be the "essence" of the universe. It claims to be a general process model for describing how complex systems — from physical processes to biological evolution, from social change to individual cognition — persist and change.
