Defining Structural Quotient (SQ): The Meaning-Editing Core of the Thought Operating System — Kakushin Structural Theory | First of the Six Foundational Pillars

This paper formally defines the structure and function of Structural Quotient (SQ), one of the six foundational pillars of the philosophical framework known as Kakushin Structural Theory.SQ is not merely the ability to “see structure.” Rather, within the theory’s core cognitive model—the Thought Operating System—SQ functions as the central module of meaning editing. It enables the retention, reconstruction, and stabilization of pre-linguistic meanings that emerge after cognitive leaps (Flight Cognition).First, we present SQ as a system of structural intelligence composed of four operational layers—Sensing, Reconfiguration, Gravitational Focus, and Mastery—supported by seven core abilities. This configuration allows SQ to be a reproducible, designable, and transferable cognitive framework.Second, we analyze how SQ interacts with other core modules of the Thought OS—namely, Flight Cognition and Structural Pressure—to form the essential cyclical circuit:Structural Pressure → Flight Cognition → SQ.Finally, this paper proposes that, in the era of AI, the essence of human intelligence must shift from that of an “information processor” to that of a “structure designer” capable of presenting meaning through form.SQ is introduced here as the operating language of future intelligence—an open and universally accessible system of meaning structuration for all humanity.
