The concept of “one” and “two” refers to the relationship of opposition and unification in the development of phenomena and is equivalent to the “antithesis” of dialectics. “One” refers to the resolution of opposition into unification, whereas “two” is the oppositional relationship itself. “One” contains “two” but “one” is also only manifested through “two.” With regard to the concept of “one and two,” different philosophers from different epochs have stressed different aspects of the dyad. Some put emphasis on the oppositional relationship and others put emphasis on the resolution into “one,” and others discuss the two aspects simultaneously. Although there are differences in their specific discussions, in the main, they can all be categorized under the concept of “one and two.”
