Abstract
This paper comparatively examines the meanings of Niels Bohr’s and Innocent Asouzu’s complementarity theories and how they differ from or relate with my compatibility theory, C={||||}. While Niels Bohr’s principle of complementarity falls under the domain of physics, Innocent Asouzu’s theory falls under African philosophy. I shall, in this paper, locate Bohr’s theory within the context of the new physics of quantum theory, especially within the wave-corpuscular problematic of the nature of electromagnetic phenomena, such as light. I shall present a firsthand meaning of Innocent Asouzu’s complementary theory. Thereafter, I shall connect Bohr’s and Asouzu’s theories with the compatibility theory. Innocent Asouzu’s complementary theory avers that anything that exists serves a missing link of reality. In other words, no entity is self-sufficient and exclusive in itself in relation. Innocent Asouzu says that there are traces of exclusive dualism in Bohr’s reasoning. Asouzu argues that incompatible opposites and contraries can co-exist.
