The men of old, wanting to clarify and diffuse throughout the empire that light which comes from looking into the heart and then acting, first set up good governments in their own states; wanting good governments in their states, they first established order in their own families, wanting order in their homes, they first disciplined themselves; desiring self-discipline they rectified their hearts; wanting to rectify their hearts, they rectified their tongues, and in desiring to rectify their tongues, they set out to extend their knowledge to the utmost.
