This study aims to establish a rigorous theoretical framework for the rational description of fate, addressing the conceptual ambiguity and logical discontinuities in existing discussions. First, we uniformly define core concepts: Fate refers to the deterministic accumulation of an individual over time, resulting from the long-term coupling of internal and external factors such as genes, environment, and social rules; Fate Tendency denotes the inherent default formation trend of Fate before intervention by Subjective Initiative; Fate Path is the specific trajectory derived from Fate that guides an individual’s life experiences; Fortune represents random events independent of Fate Tendency in the development of Fate, with the potential for chain reactions; Struggle refers to proactive efforts made by individuals to optimize their trajectories within the scope of Fate, serving as the practical carrier of Subjective Initiative; and Subjective Initiative is the inherent capacity of individuals to initiate decisions, take actions, and integrate resources based on self-awareness. We refute the contradictory philosophical view that "Fate is fixed but its formation process is random" by integrating the theory of causal continuity in time philosophy and the method of logical positivism. Furthermore, based on quantum mechanics, complex systems theory, and sociological statistical laws, we propose the dual nature of Fate—"microscopically variable and macroscopically deterministic": its flexibility originates from microscopic physical uncertainty, while its overall deterministic trend stems from macroscopic predictability. Microscopic randomness cannot directly trigger macro butterfly effects, but can gradually adjust Fate Path through accumulation (e.g., the continuous exertion of Subjective Initiative). A graphical description method is introduced to visualize the theory, and its effectiveness has been initially verified in scenarios such as life planning and psychological therapy. This framework integrates interdisciplinary perspectives, enriches the academic discourse on fate studies, and provides an operable tool for rational decision-making.
