 Mozi’s challenge to Confucianism focused on his crucial insight that the fact that traditional norms are our own, do not warrant taking them as correct. Mozi thus launched the meta-search for a way impartially to select a first-order dao. He formulates the initial version of the goal of unbiased, constant universality in morality. Both of these results, further, involved important theoretical insights into the concept of dao. The Mohists developed much of the terminology of analysis that other Chinese thinkers, including Mencius and Zhuangzi, adopted. (See  Concepts.)  Zhuangzi deployed this language with considerable skill in his skeptical undermining of all claims to special moral authority.
