Izumezu
The Logic of Complementarity (often referenced as Izumezu logic)
Book •
Jonathan Chimakonam's work on Izumezu logic introduces a trivalent logical framework to capture complementarity and contextual truth-values in African thought traditions.
The system adds a third value—often translated as 'complemented'—that can embody both truth and falsity, accommodating relational and context-dependent reasoning.
Chimakonam supplements classical laws of thought with additional principles and proposes inferential modes that allow reasoning both from general to particular and vice versa.
His logic aims to correct the misapplication of Aristotelian bivalence to African ontologies and has influenced subsequent revisions and applications in African metaphysics and comparative logic.
