Abstract:	The horizontal fragmentation of human knowledge—its organization by disciplinary convention rather than by the structure of reality—is not merely an inconvenience for librarians but an active contributor to civilizational crisis. The idea that reality is structured into integrative levels has a long history in knowledge organization, from Comte's hierarchy of sciences through Hartmann's stratified ontology to Gnoli's Integrative Levels Classification. Yet no existing system fully develops the practical consequences of this ontological structure for delineating human agency, generating predictive capacity, or reconciling ideological conflict. This paper proposes a four-realm taxonomy—Cosmological, Planetary, Ecological, and Civilizational—that extends the integrative levels tradition by introducing three contributions: a Constraint-Agency Matrix formalizing the gradient of human agency across ontological levels, a thermodynamically bounded principle of downward causation, and a diagnostic-overlay that complements rather than replaces existing operational classification systems. Adopting a structural realist position, the taxonomy treats the constraint hierarchy as a mind-independent feature of reality while acknowledging that representations of it are fallible. It is designed to accommodate all materialist cosmologies and civilizational structures within a single architecture. The framework is governed by three meta-principles—Upward Constraint, Upward Emergence, and Downward Causation—and yields two distinctive capabilities that the existing literature has not fully developed: a differentiating power that organizes knowledge by ontological dependency rather than disciplinary convention, and a predictive power that, in the manner of Mendeleev's table, identifies gaps in knowledge that horizontal classification conceals. The taxonomy is testable, falsifiable, and applicable to curriculum design, knowledge-quality assurance, civilizational risk analysis, and the reconciliation of polarized ideological positions.

Description
Abstract:	The horizontal fragmentation of human knowledge—its organization by disciplinary convention rather than by the structure of reality—is not merely an inconvenience for librarians but an active contributor to civilizational crisis. The idea that reality is structured into integrative levels has a long history in knowledge organization, from Comte's hierarchy of sciences through Hartmann's stratified ontology to Gnoli's Integrative Levels Classification. Yet no existing system fully develops the practical consequences of this ontological structure for delineating human agency, generating predictive capacity, or reconciling ideological conflict. This paper proposes a four-realm taxonomy—Cosmological, Planetary, Ecological, and Civilizational—that extends the integrative levels tradition by introducing three contributions: a Constraint-Agency Matrix formalizing the gradient of human agency across ontological levels, a thermodynamically bounded principle of downward causation, and a diagnostic-overlay that complements rather than replaces existing operational classification systems. Adopting a structural realist position, the taxonomy treats the constraint hierarchy as a mind-independent feature of reality while acknowledging that representations of it are fallible. It is designed to accommodate all materialist cosmologies and civilizational structures within a single architecture. The framework is governed by three meta-principles—Upward Constraint, Upward Emergence, and Downward Causation—and yields two distinctive capabilities that the existing literature has not fully developed: a differentiating power that organizes knowledge by ontological dependency rather than disciplinary convention, and a predictive power that, in the manner of Mendeleev's table, identifies gaps in knowledge that horizontal classification conceals.
