三法之立
Establishing the Three Standards
子墨子言曰:凡出言談、由文學之為道也,則不可而不先立義法。若言而無義,譬猶立朝夕於員鈞之上也,則雖有巧工,必不能得正焉。然今天下之情偽,未可得而識也。故使言有三法。三法者何也?有本之者,有原之者,有用之者。於其本之也?考天鬼之志,聖王之事;於其原之也?徵以先王之書;用之奈何?發而為刑。此言之三法也。
Master Mozi said: In all speech and discourse, in all matters of learning and the Way, one must first establish standards of rightness. To speak without standards is like setting up a gnomon on a round potter's wheel -- even the most skilled craftsman cannot determine anything correctly from it. Yet today the truth and falsehood of the world cannot yet be discerned. Therefore we must ensure that speech has the Three Standards. What are the Three Standards? There is the basis, the source of evidence, and the practical application. For the basis: examine the will of Heaven and the spirits, and the deeds of the sage-kings. For the source of evidence: verify against the books of the former kings. For the practical application: promulgate it as punishments and governance. These are the Three Standards of argument.
Notes
This chapter restates and elaborates the Three Standards (三法/三表) introduced in chapter 35, presenting a slightly different formulation. Here Mozi emphasizes the will of Heaven and the spirits as the primary basis, rather than the deeds of the sage-kings alone.
