This document presents The Philosophy of Integration, a standalone structural framework for observing cause, relation, and coherence within human relational systems. Rather than interpreting experience through psychological, moral, or spiritual lenses, the framework adopts a non-interpretive stance that maps how relational systems move through cause and effect. The document defines a coherent set of structural terms and principles, including relational loops, interference, mediation, fragmentation, and coherence, and demonstrates how these operate without reference to intention, meaning, or value. Integration is described not as an achieved outcome, but as the natural resolution of causal sequences when interference diminishes.
