In ancient times, those who wished to illuminate the world with virtue first brought order to their nations. Wishing to order well their nations, they first harmonized their families. Wishing to harmonize their families, they first cultivated themselves. Wishing to cultivate themselves, they first rectified their minds. Those who wished to rectify their minds first made their intentions sincere.

For the innovator has for enemies all those who derived advantages from the old order of things, whilst those who expect to be benefited by the new institutions will be but lukewarm defenders.
