Mencius 4B.19: why say difference between humans
Mencius does not exaggerate the distance between humans and animals. He insists that the difference is slight.
孟子曰：「人之所以異於禽獸者幾希，庶民去之，君子存之。舜明於庶物，察於人倫；由仁義行，非行仁義也。」
Mencius said, 'That whereby man differs from the lower animals is but small. The mass of people cast it away, while superior men preserve it. Shun clearly understood the multitude of things, and closely observed the relations of humanity. He walked along the path of benevolence and righteousness; he did not need to pursue benevolence and righteousness.'

Central question
Why does Mencius say the difference between humans and animals is slight, yet treat it as decisive?
Direct answer
Because what makes a human life truly human is not a massive outer gap but a fragile moral margin that can be lost or preserved: benevolence, righteousness, and ordered human relations.
First principle
Human nobility is not automatically guaranteed. It begins from a small margin that can either be kept or thrown away.
Why it matters
This passage fits high-intent searches around what distinguishes human beings in Mencius and deepens the site's authority on human goodness and moral psychology.
