 The Hundred Schools have different theories, and each has its own origins. For example, the relationship of Mozi, Yang Zhu, Shen Buhai, and Lord Shang to the Way of Governing is like that of an individual umbrella rib to the whole canopy and like that of an individual spoke to the whole chariot wheel. If you have any one of them, you can complete the number; if you are missing any one of them, it will not affect the utility of the whole. Each one thought that he alone had a monopoly on true governing; he did not understand the genuine disposition of Heaven and Earth. (Huainanzi 2.10, Major, Queen, et al.
