The Tetralemma Trias: A Summary of the Charta Research Program's Metalogical Investigation into Nāgārjuna's Catuṣkoṭi.

This overview paper synthesizes three interconnected studies (Meister 2025a,b,c) that constitute a comprehensive metalogical investigation into Nāgārjuna's tetralemma (catuṣkoṭi). The trias demonstrates: (1) the tetralemma necessarily presupposes identity principles (A = A, A ≠ B) in its metalanguage; (2) this presupposition is geometrically visualizable and formally veriable; (3) identity traces to a primordial source (the Ur-Matrix) prior to any operation. Together, these papers establish that radical negation depends on and cannot negate the identity it appears to oppose.
