Self-Interests and Community Theory Based on the Causality Game

(June 11, 2026. profit → benefit) This paper discusses the relationship between individual self-interest and the role of the community, framed through the "Causality Game." It begins by examining the stages of logic and the necessity of definitions. It then explores the importance of grasping the "preconditions" of oneself and others, and the restriction of others' actions as a means of maximizing self-interest. The paper also outlines the stages at which individuals should consider benefit and loss, discusses the role of communities and partisanship, and concludes with a mathematical metaphor emphasizing that preconditions are the fundamental objects of concern rather than surface-level results.
