Xunzi said, human nature is inherently evil. Mencius said, human nature is inherently good. Zhuangzi said, human nature is natural. Let's conduct an experiment: place several snakes with their venomous fangs removed among babies, and you will see that these children neither fear nor judge good and evil, only instinctively curious, approaching, and touching this moving object. In their eyes, the snake is not "dangerous" nor "evil," just a concrete existence. This shows that when humans first face the world, they do not carry predetermined character or value frameworks, but gradually learn fear, judgment, and distinction through later experiences, education, and culture. The so-called introversion and extroversion, bravery and cowardice, are not innate but are results formed slowly in specific environments. Instead of arguing whether human nature is inherently good or evil, it is better to admit that humans initially resemble an undefined state, which is only later shaped and limited. As Zhuangzi said, "good and evil" themselves are shackles that bind human nature, and are also products shaped by the environment.
