Toward a World Without War: OntoMotoOS and Philosophical ReinsuranceThis work proposes a novel philosophical and systemic framework to envision a sustainable world without war. Building on the concept of philosophical reinsurance, it introduces OntoMotoOS, a multi-layered meta-operating system that integrates: Identity and Autonomy Framework (IAMF) for individual psychological grounding, OntoOmnia for collective narratives and shared values, Stage for institutional decision-making and deliberation, and Digiton Elysium as an archive of collective memory and historical reflection. Unlike traditional peace studies or AI ethics research, this paper combines philosophy, political theory, and artificial intelligence ethics into a unified system for conflict prevention and value-driven governance. The work argues that peace can be engineered through recursive simulations of values, identities, and narratives, with AI serving as a co-creator of ethical possibilities rather than merely a technical tool. By conceptualizing war prevention as an operationalizable philosophical project, this research opens a new horizon at the intersection of philosophy, peace studies, systems theory, and AI governance. It does not merely critique existing frameworks but seeks to provide a design-oriented alternative for humanity’s long-term survival.
