 However, Mohism did advocate a first order normative dao and followed Confucianism in the assumption that an orderly society needs to follow a single constant dao. Though they developed an account of how to justify a dao and first formulated the standard of dao adequacy (constancy). What they did not notice was that those standards constituted a meta-dao—a dao for selecting and interpreting a first-order dao. This reflects their failure to reflect on the nature of dao, and then to address whether and how such a dao was knowable. They disagreed with Confucianism mainly on the content of the daoguide to be imposed on society by authority while addressing only from their own perspective how that disagreement should be resolved. Theoretical Daoism focused on the insolubility of this ru-moConfucian-Mohist debate.
