Xun Zi

Human nature is what Heaven supplies.

Human nature is such that people are born with a love of profit If they follow these inclinations, they will struggle and snatch from each other, and inclinations to defer or yield will die.

Thus, anybody who follows this nature and gives way its states will be led into quarrels and conflicts, and go against the conventions and rules of society, and will end up a criminal.

Mencius said that human nature is good. I disagree with that.

Now it is human nature to want to eat to ones fill when hungry, to want to warm up when cold, to want to rest when tired. These all are a part of people’s emotional nature.

In antiquity the sage kings recognized that men’s nature is bad and that their tendencies were not being corrected and their lawlessness controlled.

Human nature is evil, and goodness is caused by intentional activity.
