Straightening the Wood
In one line Xunzi argued that human nature is bad and goodness is made, as a craftsman steams and straightens wood.
Xunzi was a Confucian of the third century BCE who answered Mencius head on. Human nature, he wrote, is bad, and goodness is the result of deliberate effort. People are born with desires for gain and pleasure. Left alone, those desires lead to strife.
His images come from crafts. Warped wood must be steamed and pressed against a frame before it is straight. A metal blade must be put to the whetstone before it is sharp. In the same way, people need teachers, ritual and good models to become good.
He did not think goodness was fake. It is real, but made, as a pot is made from clay. Mencius and Xunzi agreed that people can become good; they disagreed about where the push comes from.
Go deeper
Xunzi also wrote that ritual was created by the ancient sage kings to set limits on desire and share out goods fairly, so that people would not fight over them. Two of his students, Han Fei and Li Si, became leading figures of Legalism, which kept his low view of human nature but dropped his trust in ritual and teachers in favor of law and punishment.
The morning class
Lin wants to exercise but never feels like it after work. Waiting for motivation has failed for a year.
She signs up for a class with a friend at 7 a.m. and lays out her shoes the night before. The structure does the work her mood would not. Months later, the habit holds, and she has started to enjoy it.
Try this today Pick one good habit that does not come naturally to you and set up a small rule or routine that supports it.
