This paper synthesizes two complementary strands—the Postulate of Negativity and the Logos of Chaos—into a unified proto-ontology. Chaos is interpreted as pure negativity; the first distinction emerges when this negativity applies to itself. In philosophy this appears as “negation of negation”, in mathematics as the algebraic law (−1) × (−1) = +1 and double negation ¬¬A ≡ A, and in ontology as the birth of Logos, the filter that extracts the possible from indeterminate potentiality. The result is an operational foundation for Metamonism: oppositions (A vs. A¯) are generated by self-applied negativity and then elaborated by conflict. We motivate this framework historically, articulate its consequences for logic, algebra, and the unity of mathematics and physics, develop testable hypotheses, and show how it renders Metamonism self-justifying while incorporating internal conflict as a source of vitality.
