This paper develops a systematic reconstruction of psychological theory grounded in the Philosophy of Belonging. It introduces a stratified ontology (SDBO–SDBEO–SDBEIO), dual temporality (synchronic structure and diachronic unfolding), and imperfect belonging as a constitutive condition of reality. The central thesis is that the self is a diachronic trajectory of belonging rather than a pre-existing entity. Psychological phenomena are reinterpreted as relational processes, and pathology as the collapse or rigidification of belonging. The paper proposes a six-step clinical architecture explaining the limitations of cognition-first therapies and formulates the belonging mediation hypothesis. This manuscript is circulated as a scholarly preprint and may differ from any future published version.
