Contradiction Medium and the Existence Question

The process of human understanding of the world starts from viewing complex chaos, proceeding to monism followed by the contradiction theory, and finally returning to complexity theory, but without giving up the pursuit of monism. Lao-Tzu and Heraclitus put forward their own theories of unity of opposites at almost the same time. The thought of unity of opposites has long been contained in the theory of yin and yang and the Book of Changes. In the ontology of information evolution, existence and nonexistence (you and wu in Chinese) can also be roughly interpreted as a contradictory relationship. Existence and nonexistence are two opposing worlds. Our understanding of existence needs medium. We can only indirectly grasp the current meaning of existence after the transmission of multilayer mediums and the distortion and loss of information. Aristotle mentioned the notion of medium, but the real world cannot be explained by his ideas. All transformational processes of existence rely on medium. The transformation process of existence and nonexistence is different from the transformation process in the domain of existence. There is no need to rely on medium.
