The culmination of Revolution is the completion of the way of revolution. 'Noble persons' refers to good and worthy people who have already followed the reform and transformed; their manifestation is dense and fine like the patterns of a leopard.
'Petty persons' are the ignorant and foolish who are hard to change; though unable to transform in heart, they also reform their faces to comply with the ruler's teachings and decrees.
The dragon and tiger are images of the great man; hence the great man is called a tiger, and the noble person is called a leopard. Human nature is fundamentally good and can always be transformed; yet there are those of bottommost folly whom even sages cannot shift.
With Yao and Shun as rulers, sage succeeding sage for over a hundred years, the transformation of the world could be called deep and enduring; yet the Youmiao and Xiang, when they came to submit and be governed, merely reformed their faces.
Once petty persons have reformed their exterior, the way of revolution can be deemed accomplished. If one goes further to punish and purge them severely, it becomes excessive, and excess is not the proper way.
Therefore, reaching the culmination of Revolution, advancing further brings misfortune. One should be steadfast and correct to maintain oneself; if revolution reaches its extreme without maintaining correctness, what has been reformed will quickly change again.
In worldly affairs, initially one worries that reform is difficult; once reformed, one worries that it cannot be preserved. Therefore, the culmination of Revolution warns that dwelling in correctness brings good fortune. Does dwelling in correctness warn only the sixth line?
It is said: It is spoken for the culmination of Revolution, and everything is included within it. Human nature is fundamentally good; why are there those who cannot be reformed?
It is said: In terms of their original nature, all are good; in terms of their endowment, there is the unshiftable bottommost folly. Those of bottommost folly are of two kinds: the self-injuring and the self-abandoning.
If a person governs oneself with goodness, there is none who cannot be shifted; even the most ignorant and foolish can advance through gradual polishing.
Only the self-injuring reject it with disbelief, and the self-abandoning sever it by refusing to act; even if a sage lives with them, he cannot transform or reach them. These are what Confucius called the bottommost fools.
Yet those who abandon and injure themselves in the world are not necessarily all foolish; often they are stubborn, aggressive, and possess ability surpassing ordinary men, such as King Zhou of Shang.
The sage, seeing them sever themselves from goodness, called them the bottommost fools; yet examining where they end up, they are truly foolish. Since they are called bottommost fools, how can they reform their faces?
It is said: Though their hearts are severed from the good way, their fear of authority and desire to avoid punishment are the same as other people's. It is precisely because they share this with other people that we know this is not the fault of their original nature.
