Zizhang asked, “Can we know what things will be like ten generations from now?”

Confucius said, “The Yin Dynasty followed the ritual of the Xia Dynasty, and what they added and subtracted from that can be known. The Zhou Dynasty followed the ritual of the Yin Dynasty, and what they added and subtracted from that can be known.

“In just this Way, what follows after the Zhou Dynasty—even to a hundred generations from now—can also be known.”

Confucius said, “I can speak of the rituals of the Xia Dynasty, but there’s little left in the state of Qii to document them. I can speak of the rituals of the Shang Dynasty, too, but there’s little left in the state of Song to document them.

“There’s not much in the way of documentation or worthy scholars in those states. If there were, I could back up my words with evidence.”

Duke Ai asked Zai Wo about the altar to the soil.

Zai Wo answered, “The Xia used pine and the Shang used cypress. But the Zhou, they say, used chestnut in order to instill the people with fear.”

After hearing about this, Confucius said, “Don’t try to explain what is already over and done with. Don’t try to criticize what’s already past. Don’t try to assign blame after something is past.”

15.11

Yan Hui asked about how to govern a state.

Confucius replied, “Follow the calendar of the Xia. Ride in the state carriage of the Yin. Wear the ceremonial cap of the Zhou. As for music, play the Shao and Wu. Abolish the tunes of the Zheng and keep slick talkers at a distance. The Zheng music is lewd and slick talkers are dangerous.”
