 The Laozi asserts that “Dao gives birth to one,” which produces “two,” and in turn the myriad beings (Chapter 42). Whereas commentators from the Han period onward generally identified the “one” with the original qi that generated the yin and yang vital forces—the “two”—at the beginning of time, Wang Bi may be said to have effected a paradigm shift in redirecting attention to the logical ground of the multiplicity and diversity of beings.
